• How can I back up my ubuntu system?

  - by Eloff

  I'm sure there's a lot of questions on here similar to this, and I've been reading them, but I still feel this warrants a new question. I want nightly, incremental backups (full disk images would waste a lot of space - unless compressed somehow.) Preferably rotating or deleting old backups when running out of space or after a fixed number of backups. I want to be able to quickly and painlessly restore my system from these backups. This is my first time running ubuntu as my main development machine and I know from my experience with it as a server and in virtual machines that I regularly manage to make it unbootable or damage it to the point of being unable to rescue it. So how would you recommend I do this? There are so many options out there I really don't know where to start. There seems to be a vocal school of thought that it's sufficient to backup your home directory and the list of installed packages from the package manager. I've already installed lots of things from source, or outside of the package manager (development tools, ides, compilers, graphics drivers, etc.) So at the very least, if I do not back up the operating system itself I need to grab all config files, all program binaries, all created but required files, etc. I'd rather backup too much than too little - an ubuntu install is tiny anyway. Also this drastically reduces the restore time, which would cost me more in my time than the extra storage space. I tried using Deja Dup to backup the root partition, excluding some things like /mnt /media /dev /proc etc. Although many websites assured me you can backup a running linux system this way - that seems to be false as it complained that it could not backup the following files: /boot/System.map-3.0.0-17-generic /boot/System.map-3.2.0-22-generic /boot/vmcoreinfo-3.0.0-17-generic /boot/vmlinuz-3.0.0-17-generic /boot/vmlinuz-3.2.0-22-generic /etc/.pwd.lock /etc/NetworkManager/system-connections/LAN Connection /etc/apparmor.d/cache/lightdm-guest-session /etc/apparmor.d/cache/sbin.dhclient /etc/apparmor.d/cache/usr.bin.evince /etc/apparmor.d/cache/usr.lib.telepathy /etc/apparmor.d/cache/usr.sbin.cupsd /etc/apparmor.d/cache/usr.sbin.tcpdump /etc/apt/trustdb.gpg /etc/at.deny /etc/ati/inst_path_default /etc/ati/inst_path_override /etc/chatscripts /etc/cups/ssl /etc/cups/subscriptions.conf /etc/cups/subscriptions.conf.O /etc/default/cacerts /etc/fuse.conf /etc/group- /etc/gshadow /etc/gshadow- /etc/mtab.fuselock /etc/passwd- /etc/ppp/chap-secrets /etc/ppp/pap-secrets /etc/ppp/peers /etc/security/opasswd /etc/shadow /etc/shadow- /etc/ssl/private /etc/sudoers /etc/sudoers.d/README /etc/ufw/after.rules /etc/ufw/after6.rules /etc/ufw/before.rules /etc/ufw/before6.rules /lib/ufw/user.rules /lib/ufw/user6.rules /lost+found /root /run/crond.reboot /run/cups/certs /run/lightdm /run/lock/whoopsie/lock /run/udisks /var/backups/group.bak /var/backups/gshadow.bak /var/backups/passwd.bak /var/backups/shadow.bak /var/cache/apt/archives/lock /var/cache/cups/job.cache /var/cache/cups/job.cache.O /var/cache/cups/ppds.dat /var/cache/debconf/passwords.dat /var/cache/ldconfig /var/cache/lightdm/dmrc /var/crash/_usr_lib_x86_64-linux-gnu_colord_colord.102.crash /var/lib/apt/lists/lock /var/lib/dpkg/lock /var/lib/dpkg/triggers/Lock /var/lib/lightdm /var/lib/mlocate/mlocate.db /var/lib/polkit-1 /var/lib/sudo /var/lib/urandom/random-seed /var/lib/ureadahead/pack /var/lib/ureadahead/run.pack /var/log/btmp /var/log/installer/casper.log /var/log/installer/debug /var/log/installer/partman /var/log/installer/syslog /var/log/installer/version /var/log/lightdm/lightdm.log /var/log/lightdm/x-0-greeter.log /var/log/lightdm/x-0.log /var/log/speech-dispatcher /var/log/upstart/alsa-restore.log /var/log/upstart/alsa-restore.log.1.gz /var/log/upstart/console-setup.log /var/log/upstart/console-setup.log.1.gz /var/log/upstart/container-detect.log /var/log/upstart/container-detect.log.1.gz /var/log/upstart/hybrid-gfx.log /var/log/upstart/hybrid-gfx.log.1.gz /var/log/upstart/modemmanager.log /var/log/upstart/modemmanager.log.1.gz /var/log/upstart/module-init-tools.log /var/log/upstart/module-init-tools.log.1.gz /var/log/upstart/procps-static-network-up.log /var/log/upstart/procps-static-network-up.log.1.gz /var/log/upstart/procps-virtual-filesystems.log /var/log/upstart/procps-virtual-filesystems.log.1.gz /var/log/upstart/rsyslog.log /var/log/upstart/rsyslog.log.1.gz /var/log/upstart/ureadahead.log /var/log/upstart/ureadahead.log.1.gz /var/spool/anacron/cron.daily /var/spool/anacron/cron.monthly /var/spool/anacron/cron.weekly /var/spool/cron/atjobs /var/spool/cron/atspool /var/spool/cron/crontabs /var/spool/cups

• Deploying a SharePoint 2007 theme using Features

  - by Kelly Jones

  I recently had a requirement to update the branding on an existing Windows SharePoint Services (WSS version 3.0) site.  I needed to update the theme, along with the master page.  An additional requirement is that my client likes to have all changes bundled up in SharePoint solutions.  This makes it much easier to move code from dev to test to prod and more importantly, makes it easier to undo code migrations if any issues would arise (I agree with this approach). Updating the theme was easy enough.  I created a new theme, along with a two new features.  The first feature, scoped at the farm level, deploys the theme, adding it to the spthemes.xml file (in the 12 hive –> \Template\layouts\1033 folder).  Here’s the method that I call from the feature activated event: private static void AddThemeToSpThemes(string id, string name, string description, string thumbnail, string preview, SPFeatureReceiverProperties properties) { XmlDocument spThemes = new XmlDocument(); //use GetGenericSetupPath to find the 12 hive folder string spThemesPath = SPUtility.GetGenericSetupPath(@"TEMPLATE\LAYOUTS\1033\spThemes.xml"); //load the spthemes file into our xmldocument, since it is just xml spThemes.Load(spThemesPath); XmlNode root = spThemes.DocumentElement; //search the themes file to see if our theme is already added bool found = false; foreach (XmlNode node in root.ChildNodes) { foreach (XmlNode prop in node.ChildNodes) { if (prop.Name.Equals("TemplateID")) { if (prop.InnerText.Equals(id)) { found = true; break; } } } if (found) { break; } } if (!found) //theme not found, so add it { //This is what we need to add: // <Templates> // <TemplateID>ThemeName</TemplateID> // <DisplayName>Theme Display Name</DisplayName> // <Description>My theme description</Description> // <Thumbnail>images/mythemethumb.gif</Thumbnail> // <Preview>images/mythemepreview.gif</Preview> // </Templates> StringBuilder sb = new StringBuilder(); sb.Append("<Templates><TemplateID>"); sb.Append(id); sb.Append("</TemplateID><DisplayName>"); sb.Append(name); sb.Append("</DisplayName><Description>"); sb.Append(description); sb.Append("</Description><Thumbnail>"); sb.Append(thumbnail); sb.Append("</Thumbnail><Preview>"); sb.Append(preview); sb.Append("</Preview></Templates>"); root.CreateNavigator().AppendChild(sb.ToString()); spThemes.Save(spThemesPath); } } Just as important, is the code that removes the theme when the feature is deactivated: private static void RemoveThemeFromSpThemes(string id) { XmlDocument spThemes = new XmlDocument(); string spThemesPath = HostingEnvironment.MapPath("/_layouts/") + @"1033\spThemes.xml"; spThemes.Load(spThemesPath); XmlNode root = spThemes.DocumentElement; foreach (XmlNode node in root.ChildNodes) { foreach (XmlNode prop in node.ChildNodes) { if (prop.Name.Equals("TemplateID")) { if (prop.InnerText.Equals(id)) { root.RemoveChild(node); spThemes.Save(spThemesPath); break; } } } } } So, that takes care of deploying the theme.  In order to apply the theme to the web, my activate feature method looks like this: public override void FeatureDeactivating(SPFeatureReceiverProperties properties) { using (SPWeb curweb = (SPWeb)properties.Feature.Parent) { curweb.ApplyTheme("myThemeName"); curweb.Update(); } } Deactivating is just as simple: public override void FeatureDeactivating(SPFeatureReceiverProperties properties) { using (SPWeb curweb = (SPWeb)properties.Feature.Parent) { curweb.ApplyTheme("none"); curweb.Update(); } } Ok, that’s the code necessary to deploy, apply, un-apply, and retract the theme.  Also, the solution (WSP file) contains the actual theme files. SO, next is the master page, which I’ll cover in my next blog post.

• GCC 4.2.1 Compiling on Cygwin(Win7 64bit) for iPhone [closed]

  - by Kenneth Noland

  Hey This is going to take a long while to explain, but the short version is that I am currently attempting to compile the LLVM GCC frontend for ARMv7 to compile apps for the Cortex-A8(iPhone 3GS). I'm running into an error from LD when compiling libgcc(part of the gcc compilation process) that has been driving me mad! The command is this: /usr/llvm-gcc-4.2-2.8.source/build/./gcc/xgcc \ -B/usr/llvm-gcc-4.2_2.8.source/build/./gcc \ -B/usr/local/arm-apple-darwin/bin \ -B/usr/local/arm-apple-darwin/lib \ -isystem /usr/local/arm-apple-darwin/include \ -isystem /usr/local/arm-apple-darwin/sys-include \ -O2 -g -W -Wall -Wwrite-strings -wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -fno-inline -dynamiclib -nodefaultlibs -W1,-dead_strip \ -marm \ -install_name /usr/local/arm-apple-darwin/lib/libgcc_s.1.dylib \ -single_module -o ./libgcc_s.1.dylib.tmp \ -W1,-exported_symbols_list,libgcc/./libgcc.map -compatibility_version 1 -current_version 1.0 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc \ ... long list of .o files ... \ -lc And the result is typically a lot of undefined references to malloc, free, exit, etc. which typically indicate that libc is not getting compiled in. After going through the list of errors that ld is throwing, I see at the top that it is attempting to pull in /usr/lib/libc.a and complains that it is not the correct platform. Okay, that makes sense, so I spent 5 minutes on google and found an answer. Turns out that if I copy the libSystem.dylib and rename it to libc.dylib, that should solve the problem, but it doesn't. I couldn't find a copy of that file on my phone, so I pulled it directly from the SDK. I then get this strange error: ld64: in /usr/local/arm-apple-darwin/lib/libc.dylib, can't re-map file, errno=22 At this point, I did everything I could think of. I grabbed a fresh copy of my /usr/lib folder from my iphone and confirmed that libSystem.dylib(and libSystem.B.dylib) wasn't there. I unpacked the raw .ipsw package for iOS 4.2.1 and once again, I could not find a copy of libSystem.dylib there either. I unpacked the iPhoneSDK and MacOS SDK and I managed to find a copy of it in both, but that error just kept persisting. I copied libSystem.dylib, libSystem.B.dylib, tried all sorts of combinations of renaming to libc.dylib and still nothing but errors. I can't find a way to get it to recognize the file and link against it. I also tried linking against the libc.a located in the iphone SDK and that didn't work either. I checked what ./xgcc was firing off, and it was my freshly built copy of arm-apple-darwin-ld64 which should be fine. A little bit of background here. I built LLVM+Clang 2.8 with no errors, and I rebuilt the ODCCTools with some light modifications to get it to compile on Cygwin(I'll post my changes in a patch along with a tutorial if I can get this to work). I also grabbed the iphone-dev "includes" and "csu" project and those completed successfully, although there really is no point to them since I can't get it to link against crt0.a. I'm running out of ideas here. Can anyone help me out on this?

• Non-standard installation (installing Linux from Linux)

  - by Evan Plaice

  So, here's my setup. I have one partition with the newest version installed, a second partition with an older version installed (as a backup just in case), a swap partition that both share, and a boot partition so the bootloader doesn't need to be setup after each upgrade. Partitions: sda1 ext3 /boot sda2 ext4 / (current version) sda3 ext4 / (old version) sda4 swap /swap sda5 ntfs (contains folders symbolically linked to /home on /) So far it has been a very good setup. I can create new boot loaders without screwing it up and adding my personal files into a new install is as simple as creating some symbolic links (the partition is NTFS in case I need to load windows on the system again). Here's the issue. I'd like to be able to drop the install into /distro on the current version and install a new version on / on the old version effectively replacing/upgrading it. The goal is to be able to just swap out new versions as they are released while maintaining redundancy in case I don't like th update. So far I have: downloaded the install.iso created a folder in /distro copied the install.iso into /distro extracted vmlinuz and initrd.lz into /distro Then I modified /boot/grub/menu.lst with the following entry: title Install Linux root (hd0,1) kernel /distro/vmlinuz initrd /distro/initrd.lz vmlinuz loads perfectly but it says it can't find initrd.lz on boot. I have also tried to uncompress the image with: unlzma < initrd.lz > initrd.img And, updating the menu.lst file to match; but that doesn't work either. I'm assuming that vmlinuz (linux kernel) loads, fires up the virtual filesystem by creating a ramdisk (initrd), mounts the iso, and launches the installer. Am I missing something here? Update: First, I wanted to say that the accepted answer would have been the best option if I was doing a normal Ubuntu install. Unfortunately, I was installing Linux Mint (which lacks the script needed to make debootstrap work. So the problem I with the above approach was, I was missing the command that vmlinuz (linux kernel) needed to execute to start boot into LiveCD mode. By looking in the /boot/grub/grub.cfg file I found what I was missing. Although this method will work, it requires that the installation files reside on their own partition. I took the easy route and used unetbootin to drop the LiveCD on a usb drive and booted from that. Like I said before. Debootstrap would have been the ideal solution here. Even though I couldn't use it I wrote down the steps it would've taken to use it. Step One: Format sda3 (the partition with the old copy of linux that's being overwritten) I used gparted to format it as ext4 from within the current linux install. How this is done varies based on what tools you prefer to use. Step Two: Mount the newly formatted partition (we'll call the mount ubuntu for simplicity) sudo mkdir /mnt/ubuntu sudo mount -o -loop /dev/sda3 /mnt/ubuntu Step Three: Get debootstrap sudo apt-get install debootstrap Step Four: Mount the install disk (replace ubuntu.iso with the name if your install disk) sudo mkdir /media/cdrom sudo mount -o loop ~/ubuntu.iso /media/cdrom Step Five: Install the OS using debootstrap (replace fiesty with the version you're installing and amd64 with your processor's architecture) sudo debootstrap --arch amd64 fiesty /mnt/ubuntu file:/media/cdrom The settings here varies. While I loaded debootstrap using an install iso, you can also have debootstrap automatically download and install if with a repository link (While most of these repositories contain debian versions I'm still not clear as to whether Ubuntu has similar repositories). Here a list of the debian package repositories and their mirrors. This is how you'd deploy debootstrap if you were doing it directly from a repository: sudo debootstrap --arch amd64 squeeze /mnt/debian http://ftp.us.debian.org/debian Here's the link that I primarily used to figure this out.

• MP3 player mpman TS300 not recognized

  - by Nick Lemaire

  I just received a mpman ts300 mp3 player for Christmas. But when I try to connect it to ubuntu (10.10) through usb it doesn't seem to be recognized. I searched for a linuxdriver but came up with nothing. I even tried installing mpman manager from the software center, but still the same problem... Has anybody got any ideas about how to fix this? Thank you edit: some additional information When I plug it in, it doesn't show up under /dev. And it is not listed in the result of 'lsusb' This is the output of 'dmesg' [19571.732541] usb 1-4: new high speed USB device using ehci_hcd and address 2 [19571.889154] scsi7 : usb-storage 1-4:1.0 [19572.883155] scsi 7:0:0:0: Direct-Access TS300 USB DISK 1.00 PQ: 0 ANSI: 0 [19572.885856] sd 7:0:0:0: Attached scsi generic sg2 type 0 [19572.887266] sd 7:0:0:0: [sdb] 7868416 512-byte logical blocks: (4.02 GB/3.75 GiB) [19573.012547] usb 1-4: reset high speed USB device using ehci_hcd and address 2 [19573.292550] usb 1-4: reset high speed USB device using ehci_hcd and address 2 [19573.572565] usb 1-4: reset high speed USB device using ehci_hcd and address 2 [19573.725019] sd 7:0:0:0: [sdb] Test WP failed, assume Write Enabled [19573.725024] sd 7:0:0:0: [sdb] Assuming drive cache: write through [19573.728521] sd 7:0:0:0: [sdb] Attached SCSI removable disk [19575.333015] sd 7:0:0:0: [sdb] 7868416 512-byte logical blocks: (4.02 GB/3.75 GiB) [19575.452547] usb 1-4: reset high speed USB device using ehci_hcd and address 2 [19580.603253] usb 1-4: device descriptor read/all, error -110 [19580.722560] usb 1-4: reset high speed USB device using ehci_hcd and address 2 [19595.842579] usb 1-4: device descriptor read/64, error -110 [19611.072656] usb 1-4: device descriptor read/64, error -110 [19611.302540] usb 1-4: reset high speed USB device using ehci_hcd and address 2 [19616.332568] usb 1-4: device descriptor read/8, error -110 [19621.462692] usb 1-4: device descriptor read/8, error -110 [19621.692551] usb 1-4: reset high speed USB device using ehci_hcd and address 2 [19626.722567] usb 1-4: device descriptor read/8, error -110 [19631.852802] usb 1-4: device descriptor read/8, error -110 [19631.962587] usb 1-4: USB disconnect, address 2 [19631.962587] sd 7:0:0:0: Device offlined - not ready after error recovery [19631.962840] sd 7:0:0:0: [sdb] Assuming drive cache: write through [19631.965104] sd 7:0:0:0: [sdb] READ CAPACITY failed [19631.965109] sd 7:0:0:0: [sdb] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK [19631.965112] sd 7:0:0:0: [sdb] Sense not available.

• Prepping the Raspberry Pi for Java Excellence (part 1)

  - by HecklerMark

  I've only recently been able to begin working seriously with my first Raspberry Pi, received months ago but hastily shelved in preparation for JavaOne. The Raspberry Pi and other diminutive computing platforms offer a glimpse of the potential of what is often referred to as the embedded space, the "Internet of Things" (IoT), or Machine to Machine (M2M) computing. I have a few different configurations I want to use for multiple Raspberry Pis, but for each of them, I'll need to perform the following common steps to prepare them for their various tasks: Load an OS onto an SD card Get the Pi connected to the network Load a JDK I've been very happy to see good friend and JFXtras teammate Gerrit Grunwald document how to do these things on his blog (link to article here - check it out!), but I ran into some issues configuring wi-fi that caused me some needless grief. Not knowing if any of the pitfalls were caused by my slightly-older version of the Pi and not being able to find anything specific online to help me get past it, I kept chipping away at it until I broke through. The purpose of this post is to (hopefully) help someone else recognize the same issues if/when they encounter them and work past them quickly. There is a great resource page here that covers several ways to get the OS on an SD card, but here is what I did (on a Mac): Plug SD card into reader on/in Mac Format it (FAT32) Unmount it (diskutil unmountDisk diskn, where n is the disk number representing the SD card) Transfer the disk image for Debian to the SD card (dd if=2012-08-08-wheezy-armel.img of=/dev/diskn bs=1m) Eject the card from the Mac (diskutil eject diskn) There are other ways, but this is fairly quick and painless, especially after you do it several times. Yes, I had to do that dance repeatedly (minus formatting) due to the wi-fi issues, as it kept killing the ability of the Pi to boot. You should be able to dramatically reduce the number of OS loads you do, though, if you do a few things with regard to your wi-fi. Firstly, I strongly recommend you purchase the Edimax EW-7811Un wi-fi adapter. This adapter/chipset has been proven with the Raspberry Pi, it's tiny, and it's cheap. Avoid unnecessary aggravation and buy this one! Secondly, visit this page for a script and instructions regarding how to configure your new wi-fi adapter with your Pi. Here is the rub, though: there is a missing step. At least for my combination of Pi version, OS version, and uncanny gift of timing and luck there was. :-) Here is the sequence of steps I used to make the magic happen: Plug your newly-minted SD card (with OS) into your Pi and connect a network cable (for internet connectivity) Boot your Pi. On the first boot, do the following things: Opt to have it use all space on the SD card (will require a reboot eventually) Disable overscan Set your timezone Enable the ssh server Update raspi-config Reboot your Pi. This will reconfigure the SD to use all space (see above). After you log in (UID: pi, password: raspberry), upgrade your OS. This was the missing step for me that put a merciful end to the repeated SD card re-imaging and made the wi-fi configuration trivial. To do so, just type sudo apt-get upgrade and give it several minutes to complete. Pour yourself a cup of coffee and congratulate yourself on the time you've just saved.  ;-) With the OS upgrade finished, now you can follow Mr. Engman's directions (to the letter, please see link above), download his script, and let it work its magic. One aside: I plugged the little power-sipping Edimax directly into the Pi and it worked perfectly. No powered hub needed, at least in my configuration. To recap, that OS upgrade (at least at this point, with this combination of OS/drivers/Pi version) is absolutely essential for a smooth experience. Miss that step, and you're in for hours of "fun". Save yourself! I'll pick up next time with more of the Java side of the RasPi configuration, but as they say, you have to cross the moat to get into the castle. Hopefully, this will help you do just that. Until next time! All the best, Mark

• 10 Best Programming Podcast 2010 Edition

  - by mbcrump

  This list is in no particular order. Just the 10 best programming podcast that I have found so far. Stack Overflow Podcast -  Jeff Atwood (of codinghorror.com) and Joel Spolsky (of joelonsoftware.com) discuss the development of their new programming community, StackOverflow.com. [This Podcast hasn’t been updated in a while, but its always great to hear more from Jeff Atwood] Hanselminutes - Hanselminutes is a weekly audio talk show with noted web developer and technologist Scott Hanselman and hosted by Carl Franklin. Scott discusses utilities and tools, gives practical how-to advice, and discusses ASP.NET or Windows issues and workarounds. [This Podcast has recently started talking about random topics like diabetes, plane travel and geek relationship tips.  I am not sure if Scott is trying to move to a more mainstream audience or not] Herding Code - A weekly discussion featuring K. Scott Allen (odetocode.com), Kevin Dente, Scott Koon (lazycoder.com), and Jon Galloway. [Great all all-around podcast that I would recommend to all] Deep Fried Bytes - Deep Fried Bytes is an audio talk show with a Southern flavor hosted by technologists and developers Keith Elder and Chris Woodruff. The show discusses a wide range of topics including application development, operating systems and technology in general. Anything is fair game if it plugs into the wall or takes a battery. [This is one that just keeps getting better] Dot Net Rocks - .NET Rocks! is an Internet Audio Talk Show for Microsoft .NET Developers. [One of the first and usually very high quality content] Connected Show - Connected Show Podcast! A podcast covering new Microsoft technology for the developer community.

[This and Polymorphic are one of my favorite podcast – Dmitry is a great host and would recommend this to all] Polymorphic Podcast - Object oriented development, architecture and best practices in .NET [Craig is a ASP.NET MVP and a great presenter. His podcast is great and it could only be better if he recorded it more often] ASP.NET Podcast - Wallace B. (Wally) McClure presents interviews and short technical talks on .NET Technologies. [Has great information on ASP.NET of course as well as iPhone Dev] Ruby on Rails Podcast - News and interviews about the Ruby language and the Rails website framework. [Even though I am not a Ruby programmer, I’ve found this podcast very interesting] Software Engineering Radio - Software Engineering Radio is a podcast targeted at the professional software developer. The goal is to be a lasting educational resource, not a newscast. Every ten days, a new episode is published that covers all topics software engineering. Episodes are either tutorials on a specific topic, or an interview with a well-known character from the software engineering world. All SE Radio episodes are original content ? we do not record conferences or talks given in other venues. Each episode comprises two speakers to ensure a lively listening experience.

• bluez 5.19 PS4 controller

  - by Athanase

  I currently have a problem when pairing my computer with a PS4 remote. On my Ubuntu 14.04 I removed everything related with bluez and bluetooth, and I built and installed bluez 5.19. Here are some useful command outputs: jean@system ~ hcitool hcitool - HCI Tool ver 5.19 jean@system ~ hcitool dev Devices: hci0 00:15:83:4C:0C:BB jean@system ~ bluetoothctl [bluetooth]# version Version 5.19 jean@system ~ bluetoothctl [NEW] Controller 00:15:83:4C:0C:BB BlueZ [default] jean@system ~ lsusb Bus 003 Device 012: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) So here is what happens. When I try to hard pair the controller with the computer, by holding the share and ps button for a while, everything works as expected and the pairing is done properly. After a hard pairing if I try the pairing by pressing the ps button only, nothings happen. In order to go it, I first power up the bluetooth dongle: jean@system ~ sudo hciconfig hciX up and then I run the bluetooh deamon bluetoothd: jean@system /usr/libexec/bluetooth ~ ./bluetoothd -d -n

• Unity 3d support for multiple X-screens

  - by stewbond

  I've installed Ubuntu 12.04 this weekend and have had problems getting Unity3d to work with my triple monitor set-up. I've installed the latest nVidia drivers for my 2 nVidia video cards and have used NVIDIA X Server Settings to configure everything. If I stick each monitor on a separate X screen, all but the primary X screen will appear white and the cursor will be a black X. I can start a terminal on this screen but cannot drag other windows to it. If I kill the "Nautilus" process, the white background disappears and I see my desktop background, but my cursor is still an X and I still cannot drag windows to it. If I enable TwinView, I can get one screen on two monitors to work properly, but the white screen remains on my third monitor. In addition, I don't like using TwinView because my full-screen applications get stretched. My current solution is to "Enable Xinerama", use all separate X screens and revert to Unity2d. I'd love a solution to this as Ubuntu 12.10 is not planned to support Unity-2d and prefer the aesthetics of 3d anyways. I can provide Xorg.conf for all configurations and any other suggested diagnostic information. Below is my closest-to-working xorg.conf: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 295.33 (buildd@zirconium) Fri Mar 30 13:38:49 UTC 2012 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" RightOf "Screen2" Screen 1 "Screen1" RightOf "Screen0" Screen 2 "Screen2" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "1" EndSection Section "Files" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Microvitec PLC MV191" HorizSync 30.0 - 81.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection Section "Monitor" Identifier "Monitor1" VendorName "Unknown" ModelName "CRT-1" HorizSync 28.0 - 55.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Monitor" Identifier "Monitor2" VendorName "Unknown" ModelName "Microvitec PLC MV191" HorizSync 30.0 - 81.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection Section "Monitor" Identifier "Monitor3" VendorName "Unknown" ModelName "Microvitec PLC MV191" HorizSync 30.0 - 81.0 VertRefresh 56.0 - 75.0 EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTS 450" BusID "PCI:1:0:0" Screen 0 EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 9500 GT" BusID "PCI:2:0:0" EndSection Section "Device" Identifier "Device2" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTS 450" BusID "PCI:1:0:0" Screen 1 EndSection Section "Device" Identifier "Device3" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTS 450" BusID "PCI:1:0:0" Screen 2 EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "DFP-0: 1280x1024_75 +0+0; DFP-0: 1280x1024 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen2" Device "Device2" Monitor "Monitor2" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "DFP-2: 1280x1024_75 +0+0; DFP-2: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen3" Device "Device3" Monitor "Monitor3" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "DFP-2: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Extensions" Option "Composite" "Disable" EndSection Other people have had similar issues.

• Using AdMob with Games that use Open GLES

  - by Vishal Kumar

  Can anyone help me integrating Admob to my game. I've used the badlogic framework by MarioZencher ... and My game is like the SuperJumper. I am unable to use AdMob after a lot of my attempts. I am new to android dev...please help me..I went thru a number of tutorials but not getting adds displayed ... I did the following... get the libraries and placed them properly My main.xml looks like this android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" / My Activity class onCreate method: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); RelativeLayout layout = new RelativeLayout(this); adView = new AdView(this, AdSize.BANNER, "a1518637fe542a2"); AdRequest request = new AdRequest(); request.addTestDevice(AdRequest.TEST_EMULATOR); request.addTestDevice("D77E32324019F80A2CECEAAAAAAAAA"); adView.loadAd(request); layout.addView(glView); RelativeLayout.LayoutParams adParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); adParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); adParams.addRule(RelativeLayout.CENTER_IN_PARENT); layout.addView(adView, adParams); setContentView(layout); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); glView = new GLSurfaceView(this); glView.setRenderer(this); //setContentView(glView); glGraphics = new GLGraphics(glView); fileIO = new AndroidFileIO(getAssets()); audio = new AndroidAudio(this); input = new AndroidInput(this, glView, 1, 1); PowerManager powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE); wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "GLGame"); } My Manifest file looks like this .... <activity android:name="com.google.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|smallestScreenSize"/> </application> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-sdk android:minSdkVersion="7" /> When I first decided to use the XML for admob purpose ..it showed no changes..it even didn't log the device id in Logcat... Later when I wrote code in the Main Activity class.. and run ... Application crashed ... with 7 errors evry time ... The android:configChanges value of the com.google.ads.AdActivity must include screenLayout. The android:configChanges value of the com.google.ads.AdActivity must include uiMode. The android:configChanges value of the com.google.ads.AdActivity must include screenSize. The android:configChanges value of the com.google.ads.AdActivity must include smallestScreenSize. You must have AdActivity declared in AndroidManifest.xml with configChanges. You must have INTERNET and ACCESS_NETWORK_STATE permissions in AndroidManifest.xml. Please help me by telling what wrong is there with the code? Can I write code only in xml files without changing the Activity class ... I will be very grateful to anyone providing support.

• Why some links appear in a new tab, others in a new window?

  - by SAMIR BHOGAYTA

  Originally, it was made to resolve problems on IE8 32 bits when you use a 32 bits OS. I changed "%ProgramFiles(x86)%" var, and now my issue is resolved for IE8 32 bits on my Windows 7 64 bits.

• OS Development. Only Few Particular Questions

  - by Total Anime Immersion

  I am new to this site as a member but have consulted its answers quite a lot of times. Besides my questions regarding OS Development hasn't been answered in any forum. In OS Dev. we make a bootloader. The org point is 7C00H. Why so? Why not 0000h? What are the last two signatures in the bootloader used for? People on every forum have answered that it is important for the system to recognize it as a bootable media. But I want a specific answer. What do each of those signatures do. I have the basic concept of a kernel. Point is.. it relates to different files required in a system. It sort of binds up everything that is individually developed. Now the thing is that that I have floating ideas in my mind regarding different aspects like keyboard, mouse, etc.. how do I put them all together? Which should I start with first? If possible please provide a step by step procedure of the startups of the kernel. Suppose I have developed my language entirely in C and Assembly. Now questions is will exe files work on my system.. if it doesn't then I have to create my own files and publish them. Which is a bad idea.. next step would be for me to go for a compiler for a language which I have designed myself. Now the point is.. How do I implement the compiler into my OS? After all this my final question is that.. How do you go about multitasking and multithreading? and I don't want to use int 21h as its dos specific.. how do I go about making files, renaming them, etc. and all assembly books teach 16 but programming.. how do i go about doing 32 bit or 64 bit with the knowledge I have.. if the basics and instructions are the same.. I don't mind.. but how do i go about otherwise? Don't tell me to give up the idea because I WON'T. And don't tell me it's too complex because I have a sharp knowledge of working of a system, C, Java, Assembly, C++ and python, C#, visual basic.. and not just basics but full fledged api developments.. but I really want to go deep into the systems part.. so I want professional help.. And I have gone through many OS project files but I want help particularly from this site as there are people with knowledge depth who can guide me the right way. And please don't suggest any books above 20$ and they should be available on flipkart as amazon charges massively for shipping and I prefer free shipping from flipkart.

• Creating a branch for every Sprint

  - by Martin Hinshelwood

  There are a lot of developers using version control these days, but a feature of version control called branching is very poorly understood and remains unused by most developers in favour of Labels. Most developers think that branching is hard and complicated. Its not! What is hard and complicated is a bad branching strategy. Just like a bad software architecture a bad branch architecture, or one that is not adhered to can prove fatal to a project. We I was at Aggreko we had a fairly successful Feature branching strategy (although the developers hated it) that meant that we could have multiple feature teams working at the same time without impacting each other. Now, this had to be carefully orchestrated as it was a Business Intelligence team and many of the BI artefacts do not lend themselves to merging. Today at SSW I am working on a Scrum team delivering a product that will be used by many hundreds of developers. SSW SQL Deploy takes much of the pain out of upgrading production databases when you are not using the Database projects in Visual Studio. With Scrum each Scrum Team works for a fixed period of time on a single sprint. You can have one or more Scrum Teams involved in delivering a product, but all the work must be merged and tested, ready to be shown to the Product Owner at the the Sprint Review meeting at the end of the current Sprint. So, what does this mean for a branching strategy? We have been using a “Main” (sometimes called “Trunk”) line and doing a branch for each sprint. It’s like Feature Branching, but with only ONE feature in operation at any one time, so no conflicts Figure: DEV folder containing the Development branches.   I know that some folks advocate applying a Label at the start of each Sprint and then rolling back if you need to, but I have always preferred the security of a branch. Like: being able to create a release from Main that has Sprint3 code even while Sprint4 is being worked on. being sure I can always create a stable build on request. Being able to guarantee a version (labels are not auditable) Be able to abandon the sprint without having to delete the code (rare I know, but would be a mess if it happened) Being able to see the flow of change sets through to a safe release It helps you find invalid dependencies when merging to Main as there may be some file that is in everyone’s Sprint branch, but never got checked in. (We had this at the merge of Sprint2) If you are always operating in this way as a standard it makes it easier to then add more scrum teams in the future. Muscle memory of this way of working. Don’t Like: Additional DB space for the branches Baseless merging between sprint branches when changes are directly ported Note: I do not think we will ever attempt this! Maybe a bit tougher to see the history between sprint branches since the changes go up through Main and down to another sprint branch Note: What you would have to do is see which Sprint the changes were made in and then check the history he same file in that Sprint. A little bit of added complexity that you would have to do anyway with multiple teams. Over time, you can end up with a lot of old unused sprint branches. Perhaps destroy with /keephistory can help in this case. Note: We ALWAYS delete the Sprint branch after it has been merged into Main. That is the theory anyway, and as you can see from the images Sprint2 has already been deleted. Why take the chance of having a problem rolling back or wanting to keep some of the code, when you can just abandon a branch and start a new one? It just seems easier and less painful to use a branch to me! What do you think?   Technorati Tags: TFS,TFS2010,Software Development,ALM,Branching

• Java in Flux: Utopia or Deuteranopia?

  - by Tori Wieldt

  What a difference a year makes, indeed. Steve Harris, Senior VP, App Server Dev, Oracle and Adam Messinger, VP, Fusion Middleware Group, Oracle presented an informative keynote at the TheServerSide Java Symposium today. With a title "Java in Flux: Utopia or Deuteranopia?" you know things are going to be interesting (see Aeon Flux if you don't get the title reference).What a YearThey started with a little background, explaining that the reactions to Oracle's acquisition of Sun (and therefore Java) one year ago varied greatly, from "Freak Out!" to "Don't Panic." From the Oracle perspective, being the steward of and key contributor to Java requires a lot of sausage making.  They admitted to Oracle's fair share of Homer Simpson-esque "D'oh" moments in the past year, which was complicated by Oracle's communication style.   "Oracle has a tradition has a saying a few things and sticking by then, in contrast to Sun who was much more open," Adam explained. "We laid out the Java roadmap and are executing on it, and we hope that speaks to our commitment."Java SEAdam talked about having a long term perspective on the Java language (20+ years), letting ideas mature in more experimental languages, then bringing them into Java. Current priorities include: JVM convergence (getting the best features of JRockit into Hotspot); support of parallel/multi-core programming, and of course, all the improvements in JDK7. The JDK7 Developer Preview is underway (please download now and report bugs!). The Oracle development team is also working on Lambda and modularity (Jigsaw) for SE 8. Less certain, but also under discussion are improvements for Java SE 9. Adam is thinking of it as a "back to basics" release. He mentioned reworking JNI, improving data integration and improved device support.Java EE To provide context about Java EE, Steve said Java EE was great at getting businesses on the internet. The success of Java EE resulted in an incredible expansion of the middleware marketplace for developers and vendors.  But with success, came more. Java EE kept piling on capabilities, but that created excess baggage.  Doing simple things was no longer so simple. That's where Java community is so valuable: "When Java EE was too complex and heavyweight, many people were happy to tell us what we were doing wrong and popularize solutions," Steve explained. Because of that feedback, the Java EE teams focused on making things simple again: POJOs and annotations, and leveraging changes in Java SE.  Steve said that "innovation doesn't happen in expert groups, it happens on the ground where developers are solving problems," and platform stewards need to pay attention and take advantage of changes that are taking place.Enter the Cloud "Developers are restless, they want cloud functionality from their own IT dept" Steve explained. With the cloud, the scope of problem has expanded to include the data center itself, with multiple tenants. To move forward, existing APIs in Java EE need to be updated to be tenant-aware, service-enabled, and EE needs to support various styles of deployment. The goal is to get all that done in Java EE 8.Adam questioned Steve about timing and schedule. "Yes, the schedule is aggressive, but it'll work" Steve said. Then Adam asked about modularization. If Java SE 8 comes out at the end of 2012, when can Java EE deliver modularization? Steve suggested that key stakeholders can come with up some pre-SE 8 agreement on how to expose the metadata about modules. He then alluded to Mark Reinhold and John Duimovich's keynote at EclipseCON next week. Stay tuned.Evil Master PlanIn conclusion, Adam finally admitted to Oracle's Evil Master Plan: 1) Invest in and improve Java SE and EE 2) Collaborate with the community 3) Broaden the marketplace for Java development. Bwaaaaaaaaahahaha! <rubs hands together>Key LinksJDK7 Developer Preview  http://jdk7.java.net/preview/Oracle Technology Network http://www.oracle.com/technetwork/java/index.htmlTheServerSide Java Symposium  http://javasymposium.techtarget.com/"Utopia or Deuteranopia?" http://en.wikipedia.org/wiki/Aeon_Flux

• What packages do I need to compile .tex documents using XeLaTeX?

  - by maria

  Hi I'm aware of the existence of similar threads on this forum. But any of replies mach to my problem. I'm using Ubuntu 10.4 and I hadn't problems with fonts till I've decided to use XeLaTeX instead of LaTeX (cf http://tex.stackexchange.com/questions/12347/typesetting-a-document-using-arabic-script/12358#12358). The problem is that I'm not able to compile any .tex document using XeLaTeX, as well as properly display XeLaTeX documentation. As I've learn thanks to mentioned thread, XeLaTeX uses the fonts availables in general in the system. I was trying yo read fontspec documentation, but it opens in pdf with a lot of white gaps and terminal output (quite long) consist mostly of errors. This are just few lines of it: Error: Missing language pack for 'Adobe-Japan1' mapping Error: Unknown font tag 'F5.1' Error (24124): No font in show Error: Unknown font tag 'F5.1' I was trying to compile simple XeLaTeX file: \documentclass{article} \usepackage{fontspec} \setmainfont{Linux Libertine O} \begin{document} Hello World! \end{document} without succes.

• LINQ to Twitter Queries with LINQPad

  - by Joe Mayo

  LINQPad is a popular utility for .NET developers who use LINQ a lot.  In addition to standard SQL queries, LINQPad also supports other types of LINQ providers, including LINQ to Twitter.  The following sections explain how to set up LINQPad for making queries with LINQ to Twitter. LINQPad comes in a couple versions and this example uses LINQPad4, which runs on the .NET Framework 4.0. 1. The first thing you'll need to do is set up a reference to the LinqToTwitter.dll. From the Query menu, select query properties. Click the Browse button and find the LinqToTwitter.dll binary. You should see something similar to the Query Properties window below. 2. While you have the query properties window open, add the namespace for the LINQ to Twitter types.  Click the Additional Namespace Imports tab and type in LinqToTwitter. The results are shown below: 3. The default query type, when you first start LINQPad, is C# Expression, but you'll need to change this to support multiple statements.  Change the Language dropdown, on the Main window, to C# Statements. 4. To query LINQ to Twitter, instantiate a TwitterContext, by typing the following into the LINQPad Query window: var ctx = new TwitterContext(); Note: If you're getting syntax errors, go back and make sure you did steps #2 and #3 properly. 5. Next, add a query, but don't materialize it, like this: var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; 6. Next, you want the output to be displayed in the LINQPad grid, so do a Dump, like this: tweets.Dump(); The following image shows the final results:   That was an unauthenticated query, but you can also perform authenticated queries with LINQ to Twitter's support of OAuth.  Here's an example that uses the PinAuthorizer (type this into the LINQPad Query window): var auth = new PinAuthorizer { Credentials = new InMemoryCredentials { ConsumerKey = "", ConsumerSecret = "" }, UseCompression = true, GoToTwitterAuthorization = pageLink => Process.Start(pageLink), GetPin = () => { // this executes after user authorizes, which begins with the call to auth.Authorize() below. Console.WriteLine("\nAfter you authorize this application, Twitter will give you a 7-digit PIN Number.\n"); Console.Write("Enter the PIN number here: "); return Console.ReadLine(); } }; // start the authorization process (launches Twitter authorization page). auth.Authorize(); var ctx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://search.twitter.com/"); var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; tweets.Dump(); This code is very similar to what you'll find in the LINQ to Twitter downloadable source code solution, in the LinqToTwitterDemo project.  For obvious reasons, I changed the value assigned to ConsumerKey and ConsumerSecret, which you'll have to obtain by visiting http://dev.twitter.com and registering your application. One tip, you'll probably want to make this easier on yourself by creating your own DLL that encapsulates all of the OAuth logic and then call a method or property on you custom class that returns a fully functioning TwitterContext.  This will help avoid adding all this code every time you want to make a query. Now, you know how to set up LINQPad for LINQ to Twitter, perform unauthenticated queries, and perform queries with OAuth. Joe

• Problem with script substitution when running script

  - by tucaz

  Hi! I'm new to Linux so this probably should be an easy fix, but I cannot see it. I have a script downloaded from official sources that is used to install additional tools for fsharp but it gives me a syntax error when running it. I tried to replace ( and ) by { and } but eventually it lead me to another error so I think this is not the problem since the script works for everybody. I read some articles that say that my bash version maybe is not the right one. I'm using Ubuntu 10.10 and here is the error: install-bonus.sh: 28: Syntax error: "(" unexpected (expecting "}") And this is line 27, 28 and 29: { declare -a DIRS=("${!3}") FILE=$2 And the full script: #! /bin/sh -e PREFIX=/usr BIN=$PREFIX/bin MAN=$PREFIX/share/man/man1/ die() { echo "$1" &2 echo "Installation aborted." &2 exit 1 } echo "This script will install additional material for F# including" echo "man pages, fsharpc and fsharpi scripts and Gtk# support for F#" echo "Interactive (root access needed)" echo "" # ------------------------------------------------------------------------------ # Utility function that searches specified directories for a specified file # and if the file is not found, it asks user to provide a directory RESULT="" searchpaths() { declare -a DIRS=("${!3}") FILE=$2 DIR=${DIRS[0]} for TRYDIR in ${DIRS[@]} do if [ -f $TRYDIR/$FILE ] then DIR=$TRYDIR fi done while [ ! -f $DIR/$FILE ] do echo "File '$FILE' was not found in any of ${DIRS[@]}.

• AppKata - Enter the next level of programming exercises

  - by Ralf Westphal

  Doing CodeKatas is all the rage lately. That´s great since widely accepted exercises are important to further the art. They provide a means of communication across platforms and allow to compare results which is part of any deliberate practice. But CodeKatas suffer from their size. They are intentionally small, so they can be done again and again. Repetition helps to build habit and to dig deeper. Over time ever new nuances of the problem or one´s approach become visible. On the other hand, though, their small size limits the methods, techniques, technologies that can be applied. To improve your TDD skills doing CodeKatas might be enough. But what about other skills? Developing on a software in a team, designing larger pieces of software, iteratively releasing software… all this and more is kinda hard to train using the tiny CodeKata problems. That´s why I´d like to present here another kind of kata I call Application Kata (or just AppKata). AppKatas are larger programming problems. They require the development of “whole” applications, i.e. not just one class or method, but bunches of classes accessible through a user interface. Also AppKata problems always are split into iterations. To get the most out of them, just look at the requirements of one iteration at a time. This way you´re closer to reality where requirements evolve in unexpected ways. So if you´re looking for more of a challenge for your software development skills, check out these AppKatas – or invent your own. AppKatas are platform independent like CodeKatas. Use whatever programming language and IDE you like. Also use whatever approach to software development you like. Just be sensitive to how easy it is to evolve your code across iterations. Reflect on what went well and what not. Compare your solutions with others. Or – for even more challenge – go for the “Coding Carousel” (see below). CSV Viewer An application to view CSV files. Sounds easy, but watch out! Requirements sometimes drastically change if the customer is happy with what you delivered. Iteration 1 Iteration 2 Iteration 3 Iteration 4 Iteration 5 (to come) Questionnaire If you like GUI programming, this AppKata might be for you. It´s about an app to let people fill out questionnaires. Also this problem might be interestin for you, if you´re into DDD. Iteration 1 Iteration 2 (to come) Iteration 3 (to come) Iteration 4 (to come) Tic Tac Toe For developers who like game programming. Although Tic Tac Toe is a trivial game, this AppKata poses some interesting infrastructure challenges. The GUI, however, stays simple; leave any 3D ambitions at home ;-) Iteration 1 Iteration 2 (to come) Iteration 3 (to come) Iteration 4 (to come) Iteration 5 (to come) Coding Carousel There are many ways you can do AppKatas. Work on them alone or in a team, pitch several devs against each other in an AppKata contest – or go around in a Coding Carousel. For the Coding Carousel you need at least 3 dev teams (regardless of size). All teams work on the same iteration at the same time. But here´s the trick: After each iteration the teams swap their code. Whatever they did for iteration n will be the basis for changes another team has to apply in iteration n+1. The code is going around the teams like in a carousel. I promise you, that´s gonna be fun! :-)

• SSIS - Connect to Oracle on a 64-bit machine (Updated for SSIS 2008 R2)

  - by jorg

  We recently had a few customers where a connection to Oracle on a 64 bit machine was necessary. A quick search on the internet showed that this could be a big problem. I found all kind of blog and forum posts of developers complaining about this. A lot of developers will recognize the following error message: Test connection failed because of an error in initializing provider. Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed. After a lot of searching, trying and debugging I think I found the right way to do it! Problems Because BIDS is a 32 bit application, as well on 32 as on 64 bit machines, it cannot see the 64 bit driver for Oracle. Because of this, connecting to Oracle from BIDS on a 64 bit machine will never work when you install the 64 bit Oracle client. Another problem is the "Microsoft Provider for Oracle", this driver only exists in a 32 bit version and Microsoft has no plans to create a 64 bit one in the near future. The last problem I know of is in the Oracle client itself, it seems that a connection will never work with the instant client, so always use the full client. There are also a lot of problems with the 10G client, one of it is the fact that this driver can't handle the "(x86)" in the path of SQL Server. So using the 10G client is no option! Solution Download the Oracle 11G full client. Install the 32 AND the 64 bit version of the 11G full client (Installation Type: Administrator) and reboot the server afterwards. The 32 bit version is needed for development from BIDS with is 32 bit, the 64 bit version is needed for production with the SQLAgent, which is 64 bit. Configure the Oracle clients (both 32 and 64 bits) by editing  the files tnsnames.ora and sqlnet.ora. Try to do this with an Oracle DBA or, even better, let him/her do this. Use the "Oracle provider for OLE DB" from SSIS, don't use the "Microsoft Provider for Oracle" because a 64 bit version of it does not exist. Schedule your packages with the SQLAgent. Background information Visual Studio (BI Dev Studio)is a 32bit application. SQL Server Management Studio is a 32bit application. dtexecui.exe is a 32bit application. dtexec.exe has both 32bit and 64bit versions. There are x64 and x86 versions of the Oracle provider available. SQLAgent is a 64bit process. My advice to BI consultants is to get an Oracle DBA or professional for the installation and configuration of the 2 full clients (32 and 64 bit). Tell the DBA to download the biggest client available, this way you are sure that they pick the right one ;-) Testing if the clients have been installed and configured in the right way can be done with Windows ODBC Data Source Administrator: Start... Programs... Administrative tools... Data Sources (ODBC) ADITIONAL STEPS FOR SSIS 2008 R2 It seems that, unfortunately, some additional steps are necessary for SQL Server 2008 R2 installations: 1. Open REGEDIT (Start… Run… REGEDIT) on the server and search for the following entry (for the 32 bits driver): HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC\MTxOCI Make sure the following values are entered: 2. Next, search for (for the 64 bits driver): HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\MSDTC\MTxOCI Make sure the same values as above are entered. 3. Reboot your server.

• #iPad at One Week: A Great Device Made with a Heavy Hand

  - by andrewbrust

  I have now had my iPad for a little over a week. In that time, Apple introduced the world to its iPhone OS 4 (and the SDK agreement’s draconian new section 3.3.1), HP introduced is Slate, and Microsoft got ready to launch Visual Studio 2010 and .NET 4.0. And through it all I have used my iPad. I've used it for email, calendar, controlling my Sonos, and writing an essay. I've used it for getting on TripIt and Twitter, and surfing the Web. I've used it for online banking, and online ordering and delivery of food. And the verdict? Honestly? I think it's a great device and I thoroughly enjoy using it. The screen is bright and vibrant. I am surprisingly fast and accurate when I type on it. The touch screen's responsiveness is nearly flawless. The software, including a number of third party applications, include pleasing animations and use of color that make it fun to get work done. And speaking of work, the Exchange integration is, dare I say it, robust. Not as full-featured as on a PC or Windows Mobile device, but still offering core functionality and, so far at least, without bugs. The UI is intuitive, not just to me, but also to my 5 1/2 year old, and also to my nearly-3-year-old son. They picked it up and, with just just a few pointers from me, they almost immediately knew what to do, whether they were looking at photos (and swiping/flicking along as they did so), using a drawing program, playing a game, or watching YouTube videos. The younger of the two of them even tried to get up on a chair and grab the thing today. He dropped it, from about 4 feet off the ground. And it's still fine. (Meanwhile, I'll be keeping it on a higher shelf.) I cannot fully describe yet what makes this form factor and this product so appealing. Maybe it's that it's an always-on device. Maybe it's just being able to hold such a nice, relatively large display so close. Maybe it's the design sensibility, that seems to pervade throughout the app ecosystem. Or maybe it's that one's fingers, and not pens or mice, are the software's preferred input device. Whatever the attraction, it's strong. And no matter how much I tend to root for Microsoft and against Apple, Cupertino has, in my mind, scored big, Can Microsoft compete? Yes, but not with the Windows 7 standard UI (nor with individual OEMs’ own UIs on top). I hope Microsoft builds a variant of the Windows Phone 7 specifically for tablet devices. And I hope they make it clear that all developers, and programming languages, are welcome to the platform. Once that’s established, the OEMs have to build great hardware with fast, responsive touch screens, under Microsoft's watchful eye. That may be the hardest part of getting this right. No matter what, Microsoft's got a fight on its hands. I don't know if it can count on winning that fight, either. But Silverlight and Live Tiles could certainly help. And so can treating developers like adults.  Apple seems intent on treating their devs like kids, and then giving the kids a curfew.  For that, dev-friendly Microsoft may one day give thanks.
