• Intel I217LM ethernet controller not detected by Ubuntu 12.04LTS

  - by Alexandr Kurilin

  My last installation of Ubuntu 12.04 on a machine using an ASUS Q87M-E motherboard with an Intel I217LM Ethernet controller has failed to detect the ethernet card. The only thing displayed by ifconfig -a is the loopback. I double-checked in the BIOS, and the controller should be online. $ rfkill list all 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no $ lspci 00:00.0 Host bridge: Intel Corporation Haswell DRAM Controller (rev 06) 00:01.0 PCI bridge: Intel Corporation Haswell PCI Express x16 Controller (rev 06) 00:02.0 VGA compatible controller: Intel Corporation Haswell Integrated Graphics Controller (rev 06) 00:03.0 Audio device: Intel Corporation Haswell HD Audio Controller (rev 06) 00:14.0 USB controller: Intel Corporation Lynx Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Lynx Point MEI Controller #1 (rev 04) 00:16.3 Serial controller: Intel Corporation Lynx Point KT Controller (rev 04) 00:19.0 Ethernet controller: Intel Corporation Device 153a (rev 04) 00:1a.0 USB controller: Intel Corporation Lynx Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Lynx Point HD Audio Controller (rev 04) 00:1d.0 USB controller: Intel Corporation Lynx Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Lynx Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Lynx Point 6-Port SATA AHCI Controller (rev 04) 00:1f.3 SMBus: Intel Corporation Lynx Point SMBus Controller (rev 04) $ lsmod Module Size Used by vesafb 13844 1 snd_hda_codec_realtek 224173 1 arc4 12529 2 joydev 17693 0 usbhid 47238 0 hid 99636 1 usbhid rfcomm 47604 0 rt73usb 31735 0 crc_itu_t 12707 1 rt73usb rt2x00usb 20808 1 rt73usb rt2x00lib 55326 2 rt73usb,rt2x00usb mac80211 506862 2 rt2x00usb,rt2x00lib cfg80211 205774 2 rt2x00lib,mac80211 eeepc_wmi 13109 0 bnep 18281 2 asus_wmi 24456 1 eeepc_wmi sparse_keymap 13890 1 asus_wmi psmouse 97485 0 bluetooth 180153 10 rfcomm,bnep ppdev 17113 0 snd_hda_intel 33719 6 snd_hda_codec 127706 2 snd_hda_codec_realtek,snd_hda_intel snd_seq_midi 13324 0 snd_hwdep 17764 1 snd_hda_codec snd_rawmidi 30748 1 snd_seq_midi serio_raw 13211 0 snd_pcm 97275 2 snd_hda_intel,snd_hda_codec snd_seq_midi_event 14899 1 snd_seq_midi snd_seq 61929 2 snd_seq_midi,snd_seq_midi_event snd_timer 29990 2 snd_pcm,snd_seq snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq parport_pc 32866 1 snd 79041 21 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_rawmidi,snd_pcm,snd_seq,snd_timer,snd_seq_device video 19651 0 soundcore 15091 1 snd wmi 19256 1 asus_wmi snd_page_alloc 18529 2 snd_hda_intel,snd_pcm mac_hid 13253 0 lp 17799 0 parport 46562 3 ppdev,parport_pc,lp $ ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1091 errors:0 dropped:0 overruns:0 frame:0 TX packets:1091 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:80048 (80.0 KB) TX bytes:80048 (80.0 KB) wlan0 Link encap:Ethernet HWaddr 00:fd:07:91:a8:b9 inet addr:172.16.42.4 Bcast:172.16.42.255 Mask:255.255.255.0 inet6 addr: fe80::2fd:7ff:fe91:a8b9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:56644 errors:0 dropped:0 overruns:0 frame:0 TX packets:36417 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:85270918 (85.2 MB) TX bytes:3413849 (3.4 MB) additionally, running sudo lshw -C network returns: *-network UNCLAIMED description: Ethernet Controller [...] I'm pretty stumped at this point.

• Increasing touch surface (#wp7dev)

  - by Laurent Bugnion

  When you design for Windows Phone 7 (or for any touch device, for that matter, and most especially small screens), you need to be very careful to give enough surface to your users’ fingers. It is easy to miss a touch on such small screens, and that can be horrifyingly frustrating. This is especially true when people are on the move, and trying to hit the control while walking and holding their device in one hand, or when the device is mounted in a car and vibrating with the engine. In my experience, a touch surface should be ideally minimum 60x60 pixels to be easy to activate on the Windows Phone 7 screen (which is, as we know, 800 pixels x 480 pixels). Ideally, I try to make my touch surfaces 80x80 pixels minimum. This causes a few design challenges of course. Using transparent backgrounds However, one thing is helping us tremendously: some surfaces can be made transparent, and yet react to touch. The secret is the following: If you have a panel that has a Null background (i.e. the Background is not set at all), then the empty surface does not react to touch. If however the Background is set to the Transparent color (or any color where the Alpha channel is set to 0), then it will react to touch. Setting a transparent background is easy. For example: <Grid Background="#00000000"> </Grid> or <Grid Background="Transparent"> </Grid> In C#: var grid = new Grid { Background = new SolidColorBrush( Colors.Transparent) }; Using negative margins Having a transparent background reactive to touch is a good start, but in addition, you must make sure that the surface is big enough for my clumsy fingers. One way to achieve that is to increase the transparent, touch-reactive surface, and reposition the element using negative margins. For example, consider the following UI. I changed the transparent background of the HyperlinkButton to Red, in order to visualize the touch surface. In this figure, the Settings HyperlinkButton is 105 pixels x 31 pixels. This is wide enough, but really small in height and easy to miss. To improve this, we can use negative margins, for instance: <HyperlinkButton Content="Settings" HorizontalAlignment="Right" VerticalAlignment="Bottom" Height="60" Margin="0,0,0,-15" /> Notice the usage of negative bottom margin to bring the HyperlinkButton back at the bottom of the main Grid’s first row, where it belongs. And the result is: Notice how the touch surface is much bigger than before. This makes the HyperlinkButton easier to reach, and improves the user experience. With the background set back to normal, the UI looks exactly the same, as it should: In summary: Remember to maximize the touch surface for your controls. Plan your design in consequence by reserving enough room around each control to allow their hit surface to be expanded as shown in this article. Do not cram too many controls in one page. If REALLY needed, use an additional page (or even better: use a Pivot control with multiple pivot items) for the controls that don’t fit on the first one. This should ensure a smoother user experience and improved touch behavior. Happy coding! Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Pondering New Technology

  - by MOSSLover

  So I have been standing at the end of a fork for a year peering down a corner looking at this way and that way trying to figure out where I fit in.  I was so enthusiastic and excited about Silverlight when it came out.  It was this amazing awesome technology that had this really cool animation and webcam/multimedia piece.  I thought if I put my money on Silverlight it’s going somewhere, then HTML 5 came out and the wind shifted.  I realized times were changing. I have been working with web technologies since I was 15 years old.  Playing with html and javascript and even css back when it first came out.  In tech years 15 years is forever.  Things change so quickly and so often.  So I guess the question is where am I heading?  The answer is mobile technology.  For some reason I was resisting change and I have no idea why.  I guess I really wanted to see more than one player.  I didn’t quite feel that Microsoft was ready with Windows Phone 7.  It was a great start, but it just didn’t feel like they went all the way.  Now with Windows 8 it feels like they are at version 2.0.  It’s like hitting Silverlight 2.0 where they finally added the .Net bits.  The path is paved, but we don’t know where it’s leading.  Then we had 3.0, 4.0, and 5.0 to mature the technology into what it is today (man I’m hoping they are going to roll some of the cool bits into other tech if they don’t exist). Anyway, I’m on board, but I’m not buying a Windows Tablet just yet.  I was hoping for a 7 inch screen from Apple around $300 or just above and a 7 inch screen from the MS side around the same price.  What I got was the Apple side, but nothing from Microsoft.  I was pretty disappointed with the $500 market price on the RT version.  I realized Microsoft is close, but not quite where Apple is today.  Yes the devices have Office that they are offering, but the sticker is just too much for a first generation device.  If you guys remember correctly the first generation iPad was quite expensive.  I guess for a 1st generation device $500 is pretty good. So I guess what I’m trying to say is that I am shifting my focus entirely away from Silverlight and more towards mobile.  I will be doing a lot of postings on iOS, Windows 8, and Windows Phone 8 with SharePoint 2013.  Since I don’t have a tablet and don’t foresee myself buying one just yet it might be mostly on the phones for right now.  I want to do a bunch of testing on various devices on what needs to be done in apps on each device.  I might add a bit on porting code from one to the other.  I think it’s going to be a lot of fun and make things flow a little better for me.  In a way it’s kind of like Star Trek 6 where they talk about the Undiscovered Country.  I’m going to jump forward completely and see where I land.

• GRUB 2 problem after Mac OS X update

  - by vallllll

  I have a MacBook Pro in dual boot Mac OS X / Ubuntu 12.04 (Precise Pangolin). When I boot it I have a rEFIt menu, and I can chose between Mac OS X and Linux. A few days ago I have updated Mac OS X from 10.7 (Lion) to 10.8 (Mountain Lion) using a .dmg image provided by my company. Since then when I select Linux in rEFIt it says: No bootable device --insert boot disk and press any key I have tried going to rEFIt partitioning tool. This is what I got: As suggested in Mac OSX Mavericks update rEFIT broken I wanted to fix the issue the same way as AndrewM, but I don't have the option "MBR table must be updated". Then I booted on Ubuntu 12.04 CD, chose repair broken system, chose root patition /dev/sda6 as this is where my Ubuntu file system is. I got a shell, but I don't really know how to repair the poblem since if it was just Windows dual boot. A GRUB update would solve the issue, but here I don't know where the GRUB 2 is installed. Here are results from Parted, and it is a bit confusing for me as the Mac partition is the one with boot: As you can see the entry 1 is an EFI system partition and is the boot partition, so I wonder if I should install GRUB there or in sda6, which is the Ubuntu filesystem. I am not sure should I work on rEFIt shell or Ubuntu. Unfortunately, I don't remember where GRUB was before update. UPDATE: using same link above I have tried RoundSparrow hilltx answer and installed rEFInd, but the result is same.... still no bootable device when I select Linux. UPDATE 2: just used alternate CD again, mounted on /dev/sda6 and the ran update-grub. It seemed to wok and started listing all my kernels. But after rebooting several times still no bootable device when I select Linux in rEFInd. UDATE 3: Have tried to boot from Ubuntu cd and select "boot from first available filesystem. I got error and dropped to grub rescue shell. I even followed the indications on this link but was unable to boot as I tried to use sdb6 but no luck UPDATE 4 as per Rob Smith request here is out put from ls -l $(find /EFI -iname "*.efi") *MACOSX -rw-r--r--@ 1 root admin 55048 29 oct 17:44 /EFI/refind/drivers_x64/btrfs_x64.efi -rw-r--r--@ 1 root admin 38888 29 oct 17:44 /EFI/refind/drivers_x64/ext2_x64.efi -rw-r--r--@ 1 root admin 39304 29 oct 17:44 /EFI/refind/drivers_x64/ext4_x64.efi -rw-r--r--@ 1 root admin 43432 29 oct 17:44 /EFI/refind/drivers_x64/hfs_x64.efi -rw-r--r--@ 1 root admin 38984 29 oct 17:44 /EFI/refind/drivers_x64/iso9660_x64.efi -rw-r--r--@ 1 root admin 43656 29 oct 17:44 /EFI/refind/drivers_x64/reiserfs_x64.efi -rw-r--r--@ 1 root admin 175016 29 oct 17:44 /EFI/refind/refind_x64.efi -rw-rw-r-- 1 root admin 73232 7 mar 2010 /EFI/tools/dbounce.efi -rw-rw-r-- 1 root admin 763248 7 mar 2010 /EFI/tools/dhclient.efi -rw-rw-r-- 1 root admin 67024 7 mar 2010 /EFI/tools/drawbox.efi -rw-rw-r-- 1 root admin 71312 7 mar 2010 /EFI/tools/dumpfv.efi -rw-rw-r-- 1 root admin 84848 7 mar 2010 /EFI/tools/dumpprot.efi -rw-rw-r-- 1 root admin 472912 7 mar 2010 /EFI/tools/ed.efi -rw-rw-r-- 1 root admin 143856 7 mar 2010 /EFI/tools/edit.efi -rw-rw-r-- 1 root admin 1801008 7 mar 2010 /EFI/tools/ftp.efi -rw-r--r--@ 1 root admin 47848 29 oct 17:44 /EFI/tools/gptsync_x64.efi -rw-rw-r-- 1 root admin 320560 7 mar 2010 /EFI/tools/hexdump.efi -rw-rw-r-- 1 root admin 286384 7 mar 2010 /EFI/tools/hostname.efi -rw-rw-r-- 1 root admin 534416 7 mar 2010 /EFI/tools/ifconfig.efi -rw-rw-r-- 1 root admin 395344 7 mar 2010 /EFI/tools/loadarg.efi -rw-rw-r-- 1 root admin 587408 7 mar 2010 /EFI/tools/ping.efi -rw-rw-r-- 1 root admin 730416 7 mar 2010 /EFI/tools/pppd.efi -rw-rw-r-- 1 root admin 561360 7 mar 2010 /EFI/tools/route.efi -rw-rw-r-- 1 root admin 1961712 7 mar 2010 /EFI/tools/shell.efi -rw-rw-r-- 1 root admin 750224 7 mar 2010 /EFI/tools/tcpipv4.efi -rw-rw-r-- 1 root admin 4048 7 mar 2010 /EFI/tools/textmode.efi -rw-rw-r-- 1 root admin 320656 7 mar 2010 /EFI/tools/which.efi *LINUX

• LexisNexis and Oracle Join Forces to Prevent Fraud and Identity Abuse

  - by Tanu Sood

  Author: Mark Karlstrand About the Writer:Mark Karlstrand is a Senior Product Manager at Oracle focused on innovative security for enterprise web and mobile applications. Over the last sixteen years Mark has served as director in a number of tech startups before joining Oracle in 2007. Working with a team of talented architects and engineers Mark developed Oracle Adaptive Access Manager, a best of breed access security solution.The world’s top enterprise software company and the world leader in data driven solutions have teamed up to provide a new integrated security solution to prevent fraud and misuse of identities. LexisNexis Risk Solutions, a Gold level member of Oracle PartnerNetwork (OPN), today announced it has achieved Oracle Validated Integration of its Instant Authenticate product with Oracle Identity Management.Oracle provides the most complete Identity and Access Management platform. The only identity management provider to offer advanced capabilities including device fingerprinting, location intelligence, real-time risk analysis, context-aware authentication and authorization makes the Oracle offering unique in the industry. LexisNexis Risk Solutions provides the industry leading Instant Authenticate dynamic knowledge based authentication (KBA) service which offers customers a secure and cost effective means to authenticate new user or prove authentication for password resets, lockouts and such scenarios. Oracle and LexisNexis now offer an integrated solution that combines the power of the most advanced identity management platform and superior data driven user authentication to stop identity fraud in its tracks and, in turn, offer significant operational cost savings. The solution offers the ability to challenge users with dynamic knowledge based authentication based on the risk of an access request or transaction thereby offering an additional level to other authentication methods such as static challenge questions or one-time password when needed. For example, with Oracle Identity Management self-service, the forgotten password reset workflow utilizes advanced capabilities including device fingerprinting, location intelligence, risk analysis and one-time password (OTP) via short message service (SMS) to secure this sensitive flow. Even when a user has lost or misplaced his/her mobile phone and, therefore, cannot receive the SMS, the new integrated solution eliminates the need to contact the help desk. The Oracle Identity Management platform dynamically switches to use the LexisNexis Instant Authenticate service for authentication if the user is not able to authenticate via OTP. The advanced Oracle and LexisNexis integrated solution, thus, both improves user experience and saves money by avoiding unnecessary help desk calls. Oracle Identity and Access Management secures applications, Juniper SSL VPN and other web resources with a thoroughly modern layered and context-aware platform. Users don't gain access just because they happen to have a valid username and password. An enterprise utilizing the Oracle solution has the ability to predicate access based on the specific context of the current situation. The device, location, temporal data, and any number of other attributes are evaluated in real-time to determine the specific risk at that moment. If the risk is elevated a user can be challenged for additional authentication, refused access or allowed access with limited privileges. The LexisNexis Instant Authenticate dynamic KBA service plugs into the Oracle platform to provide an additional layer of security by validating a user's identity in high risk access or transactions. The large and varied pool of data the LexisNexis solution utilizes to quiz a user makes this challenge mechanism even more robust.

• Realtek RTL8111/8168B wired network doesn't work anymore

  - by Radar4002

  This sounds like it's a common problem upgrading 11.04, but I am having trouble finding a common solution, and one that will work for me. I just applied updates via the update manager and now my wired network connection is down. I know Ubuntu network settings is the issue, because I have a dual-boot with Win 7 and my network/internet is fine on Win 7. I don't know too much about networking, so what can I do to trouble shoot this issue? I can choose an older grub version, 2.6.38-8 instead of 2.6.38-11 and this does not resolve the issue.

• Oracle Social Network Developer Challenge: Fishbowl Solutions

  - by Kellsey Ruppel

  Originally posted by Jake Kuramoto on The Apps Lab blog. Today, I give you the final entry in the Oracle Social Network Developer Challenge, held last week during OpenWorld. This one comes from Friend of the ‘Lab and Fishbowl Solutions (@fishbowle20) hacker, John Sim (@jrsim_uix), whom you might remember from his XBox Kinect demo at COLLABORATE 12 (presentation slides and abstract) hacks and other exploits with WebCenter. We put this challenge together specifically for developers like John, who like to experiment with new tools and push the envelope of what’s possible and build cool things, and as you can see from his entry John did just that, mashing together Google Maps and Oracle Social Network into a mobile app built with PhoneGap that uses the device’s camera and GPS to keep teams on the move in touch. He calls it a Mobile GeoTagging Solution, but I think Avengers Assemble! would have equally descriptive, given that was obviously his inspiration. Here’s his description of the mobile app: My proposed solution was to design and simplify GeoLocation mapping, and automate updates for users and teams on the move; who don’t have access to a laptop or want to take their ipads out – but allow them to make quick updates to OSN and upload photos taken from their mobile device – there and then. As part of this; the plan was to include a rules engine that could be configured by the user to allow the device to automatically update and post messages when they arrived at a set location(s). Inspiration for this came from on{x} – automate your life. Unfortunately, John didn’t make it to the conference to show off his hard work in person, but luckily, he had a colleague from Fishbowl and a video to showcase his work.    Here are some shots of John’s mobile app for your viewing pleasure: John’s thinking is sound. Geolocation is usually relegated to consumer use cases, thanks to services like foursquare, but distributed teams working on projects out in the world definitely need a way to stay in contact. Consider a construction job. Different contractors all converge on a single location, and time is money. Rather than calling or texting each other and risking a distracted driving accident, an app like John’s allows everyone on the job to see exactly where the other contractors are. Using his GPS rules, they could easily be notified about how close each is to the site, definitely useful when you have a flooring contractor sitting idle, waiting for an electrician to finish the wiring. The best part is that the project manager or general contractor could stay updated on all the action (or inaction) using Oracle Social Network, either sitting at a desk using the browser app or desktop client or on the go, using one of the native mobile apps built for Oracle Social Network. I can see this being used by insurance adjusters too, and really any team that, erm, assembles at a given spot. Of course, it’s also useful for meeting at the pub after the day’s work is done. Beyond people, this solution could also be implemented for physical objects that are in route to a destination. Say you’re a customer waiting on rail shipment or a package delivery. You could track your valuable’s whereabouts easily as they report their progress via checkins. If they deviated from the GPS rules, you’d be notified. You might even be able to get a picture into Oracle Social Network with some light hacking. Thanks to John and his colleagues at Fishbowl for participating in our challenge. We hope everyone had a good experience. Make sure to check out John’s blog post on his work and the experience using Oracle Social Network. Although this is the final, official entry we had, tomorrow, I’ll show you the work of someone who finished code, but wasn’t able to make the judging event. Stay tuned.

• C# 5 Async, Part 2: Asynchrony Today

  - by Reed

  The .NET Framework has always supported asynchronous operations.  However, different mechanisms for supporting exist throughout the framework.  While there are at least three separate asynchronous patterns used through the framework, only the latest is directly usable with the new Visual Studio Async CTP.  Before delving into details on the new features, I will talk about existing asynchronous code, and demonstrate how to adapt it for use with the new pattern. The first asynchronous pattern used in the .NET framework was the Asynchronous Programming Model (APM).  This pattern was based around callbacks.  A method is used to start the operation.  It typically is named as BeginSomeOperation.  This method is passed a callback defined as an AsyncCallback, and returns an object that implements IAsyncResult.  Later, the IAsyncResult is used in a call to a method named EndSomeOperation, which blocks until completion and returns the value normally directly returned from the synchronous version of the operation.  Often, the EndSomeOperation call would be called from the callback function passed, which allows you to write code that never blocks. While this pattern works perfectly to prevent blocking, it can make quite confusing code, and be difficult to implement.  For example, the sample code provided for FileStream’s BeginRead/EndRead methods is not simple to understand.  In addition, implementing your own asynchronous methods requires creating an entire class just to implement the IAsyncResult. Given the complexity of the APM, other options have been introduced in later versions of the framework.  The next major pattern introduced was the Event-based Asynchronous Pattern (EAP).  This provides a simpler pattern for asynchronous operations.  It works by providing a method typically named SomeOperationAsync, which signals its completion via an event typically named SomeOperationCompleted. The EAP provides a simpler model for asynchronous programming.  It is much easier to understand and use, and far simpler to implement.  Instead of requiring a custom class and callbacks, the standard event mechanism in C# is used directly.  For example, the WebClient class uses this extensively.  A method is used, such as DownloadDataAsync, and the results are returned via the DownloadDataCompleted event. While the EAP is far simpler to understand and use than the APM, it is still not ideal.  By separating your code into method calls and event handlers, the logic of your program gets more complex.  It also typically loses the ability to block until the result is received, which is often useful.  Blocking often requires writing the code to block by hand, which is error prone and adds complexity. As a result, .NET 4 introduced a third major pattern for asynchronous programming.  The Task<T> class introduced a new, simpler concept for asynchrony.  Task and Task<T> effectively represent an operation that will complete at some point in the future.  This is a perfect model for thinking about asynchronous code, and is the preferred model for all new code going forward.  Task and Task<T> provide all of the advantages of both the APM and the EAP models – you have the ability to block on results (via Task.Wait() or Task<T>.Result), and you can stay completely asynchronous via the use of Task Continuations.  In addition, the Task class provides a new model for task composition and error and cancelation handling.  This is a far superior option to the previous asynchronous patterns. The Visual Studio Async CTP extends the Task based asynchronous model, allowing it to be used in a much simpler manner.  However, it requires the use of Task and Task<T> for all operations.

• Prefilling an SMS on Mobile Devices with the sms: Uri Scheme

  - by Rick Strahl

  Popping up the native SMS app from a mobile HTML Web page is a nice feature that allows you to pre-fill info into a text for sending by a user of your mobile site. The syntax is a bit tricky due to some device inconsistencies (and quite a bit of wrong/incomplete info on the Web), but it's definitely something that's fairly easy to do.In one of my Mobile HTML Web apps I need to share a current location via SMS. While browsing around a page I want to select a geo location, then share it by texting it to somebody. Basically I want to pre-fill an SMS message with some text, but no name or number, which instead will be filled in by the user.What worksThe syntax that seems to work fairly consistently except for iOS is this:sms:phonenumber?body=messageFor iOS instead of the ? use a ';' (because Apple is always right, standards be damned, right?):sms:phonenumber;body=messageand that works to pop up a new SMS message on the mobile device. I've only marginally tested this with a few devices: an iPhone running iOS 6, an iPad running iOS 7, Windows Phone 8 and a Nexus S in the Android Emulator. All four devices managed to pop up the SMS with the data prefilled.You can use this in a link:<a href="sms:1-111-1111;body=I made it!">Send location via SMS</a>or you can set it on the window.location in JavaScript:window.location ="sms:1-111-1111;body=" + encodeURIComponent("I made it!");to make the window pop up directly from code. Notice that the content should be URL encoded - HTML links automatically encode, but when you assign the URL directly in code the text value should be encoded.Body onlyI suspect in most applications you won't know who to text, so you only want to fill the text body, not the number. That works as you'd expect by just leaving out the number - here's what the URLs look like in that case:sms:?body=messageFor iOS same thing except with the ;sms:;body=messageHere's an example of the code I use to set up the SMS:var ua = navigator.userAgent.toLowerCase(); var url; if (ua.indexOf("iphone") > -1 || ua.indexOf("ipad") > -1) url = "sms:;body=" + encodeURIComponent("I'm at " + mapUrl + " @ " + pos.Address); else url = "sms:?body=" + encodeURIComponent("I'm at " + mapUrl + " @ " + pos.Address); location.href = url;and that also works for all the devices mentioned above.It's pretty cool that URL schemes exist to access device functionality and the SMS one will come in pretty handy for a number of things. Now if only all of the URI schemes were a bit more consistent (damn you Apple!) across devices...© Rick Strahl, West Wind Technologies, 2005-2013Posted in IOS  JavaScript  HTML5   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• JCP Awards 10 Year Retrospective

  - by Heather VanCura

  As we celebrate 10 years of JCP Program Award recognition in 2012,  take a look back in the Retrospective article covering the history of the JCP awards.  Most recently, the JCP awards were  celebrated at JavaOne Latin America in Brazil, where SouJava was presented the JCP Member of the Year Award for 2012 (won jointly with the London Java Community) for their contributions and launch of the Global Adopt-a-JSR Program. This is also a good time to honor the JCP Award Nominees and Winners who have been designated as Star Spec Leads.  Spec Leads are key to the Java Community Process (JCP) program. Without them, none of the Java Specification Requests (JSRs) would have begun, much less completed and become implemented in shipping products.  Nominations for 2012 Start Spec Leads are now open until 31 December. The Star Spec Lead program recognizes Spec Leads who have repeatedly proven their merit by producing high quality specifications, establishing best practices, and mentoring others. The point of such honor is to endorse the good work that they do, showcase their methods for other Spec Leads to emulate, and motivate other JCP program members and participants to get involved in the JCP program. Ed Burns – A Star Spec Lead for 2009, Ed first got involved with the JCP program when he became co-Spec Lead of JSR 127, JavaServer Faces (JSF), a role he has continued through JSF 1.2 and now JSF 2.0, which is JSR 314. Linda DeMichiel – Linda thus involved in the JCP program from its very early days. She has been the Spec Lead on at least three JSRs and an EC member for another three. She holds a Ph.D. in Computer Science from Stanford University. Gavin King – Nominated as a JCP Outstanding Spec Lead for 2010, for his work with JSR 299. His endorsement said, “He was not only able to work through disputes and objections to the evolving programming model, but he resolved them into solutions that were more technically sound, and which gained support of its pundits.” Mike Milikich –  Nominated for his work on Java Micro Edition (ME) standards, implementations, tools, and Technology Compatibility Kits (TCKs), Mike was a 2009 Star Spec Lead for JSR 271, Mobile Information Device Profile 3. David Nuescheler – Serving as the CTO for Day Software, acquired by Adobe Systems, David has been a key player in the growth of the company’s global content management solution. In 2002, he became Spec Lead for JSR 170, Content Repository for Java Technology API, continuing for the subsequent version, JSR 283. Bill Shannon – A well-respected name in the Java community, Bill came to Oracle from Sun as a Distinguished Engineer and is still performing at full speed as Spec Lead for JSR 342, Java EE 7,  as an alternate EC member, and hands-on problem solver for the Java community as a whole. Jim Van Peursem – Jim holds a PhD in Computer Engineering. He was part of the Motorola team that worked with Sun labs on the Spotless VM that became the KVM. From within Motorola, Jim has been responsible for many aspects of Java technology deployment, from an independent Connected Limited Device Configuration (CLDC) and Mobile Information Device Profile (MIDP) implementations, to handset development, to working with the industry in defining many related standards. Participation in the JCP Program goes well beyond technical proficiency. The JCP Awards Program is an attempt to say “Thank You” to all of the JCP members, Expert Group Members, Spec Leads, and EC members who give their time to contribute to the evolution of Java technology.

• Sparse virtual machine disk image resizing weirdness?

  - by Matt H

  I have a partitioned virtual machine disk image created by vmware. What I want to do is resize that by 10GB. The file size is showing as 64424509440. Or 60GB. So I ran this: dd if=/dev/zero of=./win7.img seek=146800640 count=0 It ran without errors and I can verify the new size is in fact 75161927680 bytes or 70GB. This is where it gets a little odd. I started the guest domain in xen which is a Windows 7 enterprise machine. What I was expecting to see in diskmgmt.msc is 2 partitions. 1 system partition at the start of around 100MB and near 60GB partition (which is C drive) followed by around 10GB of free space. Actually what I saw was a 70GB partition!?! That confused me... so I decided to run the Check Disk which when you set it on the C drive it asks you to reboot so it'll run on boot. So I did that and during the boot it ran the checks. It got all the way through stage 3 and didn't show any errors at all. Looked at the partitions in disk manager and now C drive has shrunk back to 60GB and there is no free space. What gives? Ok, I thought I'd try mounting it under Dom0 and examining it with fdisk. This is what I get when mounted sudo xl block-attach 0 tap:aio:/home/xen/vms/otoy_v1202-xen.img xvda w sudo fdisk -l /dev/xvda Disk /dev/xvda: 64.4 GB, 64424509440 bytes 255 heads, 63 sectors/track, 7832 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: 0x582dfc96 Device Boot Start End Blocks Id System /dev/xvda1 * 1 13 102400 7 HPFS/NTFS Partition 1 does not end on cylinder boundary. /dev/xvda2 13 7833 62810112 7 HPFS/NTFS Note the cylinder boundary comment. When I run sudo cfdisk /dev/xvda I get: FATAL ERROR: Bad primary partition 1: Partition ends in the final partial cylinder Press any key to exit cfdisk So I guess this is a bigger problem than first thought. How can I fix this? EDIT: Oops, the cylinder boundary thing is not a problem at all since disks have used LBA etc. So that threw me for a moment... still the problem exists... Now this output looks a little different. sudo sfdisk -uS -l /dev/xvda Disk /dev/xvda: 7832 cylinders, 255 heads, 63 sectors/track Units = sectors of 512 bytes, counting from 0 Device Boot Start End #sectors Id System /dev/xvda1 * 2048 206847 204800 7 HPFS/NTFS /dev/xvda2 206848 125827071 125620224 7 HPFS/NTFS /dev/xvda3 0 - 0 0 Empty /dev/xvda4 0 - 0 0 Empty BTW: I do have a backup of the image so if you help me mess it up that's ok. EDIT: sudo parted /dev/xvda print free Model: Xen Virtual Block Device (xvd) Disk /dev/xvda: 64.4GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 32.3kB 1049kB 1016kB Free Space 1 1049kB 106MB 105MB primary ntfs boot 2 106MB 64.4GB 64.3GB primary ntfs 64.4GB 64.4GB 1049kB Free Space Cool. Linux is showing free space is 10GB which is what I expect. The problem is windows isn't seeing this?

• PowerShell: Read Excel to Create Inserts

  - by BuckWoody

  I’m writing a series of articles on how to migrate “departmental” data into SQL Server. I also hold workshops on the entire process – from discovering that the data exists to the modeling process and then how to design the Extract, Transform and Load (ETL) process. Finally I write about (and teach) a few methods on actually moving the data. One of those options is to use PowerShell. There are a lot of ways even with that choice, but the one I show is to read two columns from the spreadsheet and output statements that would insert the data using a stored procedure. Of course, you could re-write this as INSERT statements, out to a text file for bcp, or even use a database connection in the script to move the data directly from Excel into SQL Server. This snippet won’t run on your system, of course – it assumes a Microsoft Office Excel 2007 spreadsheet located at c:\temp called VendorList.xlsx. It looks for a tab in that spreadsheet called Vendors. The statement that does the writing just uses one column: Vendor Code. Here’s the breakdown of what I’m doing: In the first block, I connect to Microsoft Office Excel. That connection string is specific to Excel 2007, so if you need a different version you’ll need to look that up. In the second block I set up a selection from the entire spreadsheet based on that tab. Note that if you’re only after certain data you shouldn’t get the whole spreadsheet – that’s just good practice. In the next block I create the text I want, inserting the Vendor Code field as I go. Finally I close the connection. Enjoy! $ExcelConnection= New-Object -com "ADODB.Connection" $ExcelFile="c:\temp\VendorList.xlsx" $ExcelConnection.Open("Provider=Microsoft.ACE.OLEDB.12.0;` Data Source=$ExcelFile;Extended Properties=Excel 12.0;") $strQuery="Select * from [Vendors$]" $ExcelRecordSet=$ExcelConnection.Execute($strQuery) do { Write-Host "EXEC sp_InsertVendors '" $ExcelRecordSet.Fields.Item("Vendor Code").Value "'" $ExcelRecordSet.MoveNext()} Until ($ExcelRecordSet.EOF) $ExcelConnection.Close() Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary.

• what is the best way to use loops to detect events while the main loop is running?

  - by yao jiang

  I am making an "game" that has pathfinding using pygame. I am using Astar algo. I have a main loop which draws the whole map. In the loop I check for events. If user press "enter" or "space", random start and end are selected, then animation starts and it will try to get from start to end. My draw function is stupid as hell right now, it works as expected but I feel that I am doing it wrong. It'll draw everything to the end of the animation. I am also detecting events in there as well. What is a better way of implementing the draw function such that it will draw one "step" at a time while checking for events? animating = False; while loop: check events: if not animating: # space or enter press will choose random start/end coords if enter_pressed or space_pressed: start, end = choose_coords route = find_route(start, end) draw(start, end, grid, route) else: # left click == generate an event to block the path # right click == user can choose a new destination if left_mouse_click: gen_event() reroute() elif right_mouse_click: new_end = new_end() new_start = current_pos() route = find_route(new_start, new_end) draw(new_start, new_end, grid, route) # draw out the grid def draw(start, end, grid, route_coord): # draw the end coords color = red; pick_image(screen, color, width*end[1],height*end[0]); pygame.display.flip(); # then draw the rest of the route for i in range(len(route_coord)): # pausing because we want animation time.sleep(speed); # get the x/y coords x,y = route_coord[i]; event_on = False; if grid[x][y] == 2: color = green; elif grid[x][y] == 3: color = blue; for event in pygame.event.get(): if event.type == pygame.MOUSEBUTTONDOWN: if event.button == 3: print "destination change detected, rerouting"; # get mouse position, px coords pos = pygame.mouse.get_pos(); # get grid coord c = pos[0] // width; r = pos[1] // height; grid[r][c] = 4; end = [r, c]; elif event.button == 1: print "user generated event"; pos = pygame.mouse.get_pos(); # get grid coord c = pos[0] // width; r = pos[1] // height; # mark it as a block for now grid[r][c] = 1; event_on = True; if check_events([x,y]) or event_on: # there is an event # mark it as a block for now grid[y][x] = 1; pick_image(screen, event_x, width*y, height*x); pygame.display.flip(); # then find a new route new_start = route_coord[i-1]; marked_grid, route_coord = find_route(new_start, end, grid); draw(new_start, end, grid, route_coord); return; # just end draw here so it wont throw the "index out of range" error elif grid[x][y] == 4: color = red; pick_image(screen, color, width*y, height*x); pygame.display.flip(); # clear route coord list, otherwise itll just add more unwanted coords route_coord_list[:] = [];

Electric pulses are sent to the write head, and the resulting magnetic patterns are recorded on the surface below with different patterns for positive and negative currents The physical characteristics of a magnetic disk   Summarize from book   The factors that play a role in the performance of a disk Seek time – the time it takes to position the head at the track Rotational delay / latency – the time it takes for the beginning of the sector to reach the head Access time – the sum of the seek time and rotational delay Transfer time – the time it takes to transfer data RAID The rate of improvement in secondary storage performance has been considerably less than the rate for processors and main memory. Thus secondary storage has become a bit of a bottleneck. RAID works on the concept that if one disk can be pushed so far, additional gains in performance are to be had by using multiple parallel components. Points to note about RAID… RAID is a set of physical disk drives viewed by the operating system as a single logical drive Data is distributed across the physical drives of an array in a scheme known as striping Redundant disk capacity is used to store parity information, which guarantees data recoverability in case of a disk failure (not supported by RAID 0 or RAID 1) Interesting to note that the increase in the number of drives, increases the probability of failure. To compensate for this decreased reliability RAID makes use of stored parity information that enables the recovery of data lost due to a disk failure.   The RAID scheme consists of 7 levels…   Category Level Description Disks Required Data Availability Large I/O Data Transfer Capacity Small I/O Request Rate Striping 0 Non Redundant N Lower than single disk Very high Very high for both read and write Mirroring 1 Mirrored 2N Higher than RAID 2 – 5 but lower than RAID 6 Higher than single disk Up to twice that of a signle disk for read Parallel Access 2 Redundant via Hamming Code N + m Much higher than single disk Highest of all listed alternatives Approximately twice that of a single disk Parallel Access 3 Bit interleaved parity N + 1 Much higher than single disk Highest of all listed alternatives Approximately twice that of a single disk Independent Access 4 Block interleaved parity N + 1 Much higher than single disk Similar to RAID 0 for read, significantly lower than single disk for write Similar to RAID 0 for read, significantly lower than single disk for write Independent Access 5 Block interleaved parity N + 1 Much higher than single disk Similar to RAID 0 for read, lower than single disk for write Similar to RAID 0 for read, generally  lower than single disk for write Independent Access 6 Block interleaved parity N + 2 Highest of all listed alternatives Similar to RAID 0 for read; lower than RAID 5 for write Similar to RAID 0 for read, significantly lower than RAID 5  for write   Read page 215 – 221 for detailed explanation on RAID levels Optical Memory There are a variety of optical-disk systems available. Read through the table on page 222 – 223 Some of the devices include… CD CD-ROM CD-R CD-RW DVD DVD-R DVD-RW Blue-Ray DVD Magnetic Tape Most modern systems use serial recording – data is lade out as a sequence of bits along each track. The typical recording used in serial is referred to as serpentine recording. In this technique when data is being recorded, the first set of bits is recorded along the whole length of the tape. When the end of the tape is reached the heads are repostioned to record a new track, and the tape is again recorded on its whole length, this time in the opposite direction. That process continued back and forth until the tape is full. To increase speed, the read-write head is capable of reading and writing a number of adjacent tracks simultaneously. Data is still recorded serially along individual tracks, but blocks in sequence are stored on adjacent tracks as suggested. A tape drive is a sequential access device. Magnetic tape was the first kind of secondary memory. It is still widely used as the lowest-cost, slowest speed member of the memory hierarchy.

• How to Speed Up Any Android Phone By Disabling Animations

  - by Chris Hoffman

  Android phones — and tablets, too — display animations when moving between apps and screens. These animations look very slick, but they waste time — especially on fast phones, which could switch between apps instantly if not for the animations. Disabling these animations will speed up navigating between different apps and interface screens on your phone, saving you time. You can also speed up the animations if you’d rather see them. Access the Developer Options Menu First, we’ll need to access the Developer Options menu. It’s hidden by default so Android users won’t stumble across it unless they’re actually looking for it. To access the Developer Options menu, open the Settings screen, scroll down to the bottom of the list, and tap the About phone or About tablet option. Scroll down to the Build number field and tap it repeatedly. Eventually, you’ll see a message appear saying “You are now a developer!”. The Developer options submenu now appears on the Settings screen. You’ll find it near the bottom of the list, just above the About phone or About tablet option. Disable Interface Animations Open the Developer Options screen and slide the switch at the top of the screen to On. This allows you to change the hidden options on this screen. If you ever want to re-enable the animations and revert your changes, all you have to do is slide the Developer Options switch back to Off. Scroll down to the Drawing section. You’ll find the three options we want here — Window animation scale, Transition animation scale, and Animator duration scale. Tap each option and set it to Animation off to disable the associated animations. If you’d like to speed up the animations without disabling them entirely, select the Animation .5x option instead. If you’re feeling really crazy, you can even select longer animation durations. You can make the animations take as much as ten times longer with the Animation 10x setting. The Animator duration scale option applies to the transition animation that appears when you tap the app drawer button on your home screen.  Your change here won’t take effect immediately — you’ll have to restart Android’s launcher after changing the Animator duration scale setting. To restart Android’s launcher, open the Settings screen, tap Apps, swipe over to the All category, scroll down, and tap the Launcher app. Tap the Force stop button to forcibly close the launcher, then tap your device’s home button to re-launch the launcher. Your app drawer will now open immediately, too. Now whenever you open an app or transition to a new screen, it will pop up as quickly as possible — no waiting for animations and wasting processing power rendering them. How much of a speed improvement you’ll see here depends on your Android device and how fast it is. On our Nexus 4, this change makes many apps appear and become usable instantly if they’re running in the background. If you have a slower device, you may have to wait a moment for apps to be usable. That’s one of the big reasons why Android and other operating systems use animations. Animations help paper over delays that can occur while the operating system loads the app.

• Fresh Ubuntu Install - Grub not loading

  - by Ryan Sharp

  System Ubuntu 12.04 64-bit Windows 7 SP1 Samsung 64GB SSD - OS' Samsung 1TB HDD - Games, /Home, Swap WD 300'ishGB HDD - Backup Okay, so I'm very frustrated, so please excuse me if I miss anything out as my head is clouded by anger and impatience, etc. I'll try me best, though. First of all, I'll explain how I got to my predicament. I finally got my new SSD. I firstly installed Windows, which completed without a hitch. Afterwards, I tried to install Ubuntu, which failed several times due to problems irrelevant to this question, but I mention this to explain my frustrations, sorry. Anyway, I finally installed Ubuntu. However, I chose the 'bootloader' to be installed on the same partition as where I was installing the Ubuntu Root partition, as that was what I believed to be the best choice. It was of my thinking that it was supposed to go on the same partition and on the SSD, which is my OS drive, though with my problem, it apparently was wrong. So I tried to fix it by checking guides and following their directions, but seemed to have messed it up even more. Here is what I receive after I use the fdisk -l command: (I also added explanations for which I used each partition for) Disk /dev/sda: 64.0 GB, 64023257088 bytes 255 heads, 63 sectors/track, 7783 cylinders, total 125045424 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x324971d1 Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 208896 48957439 24374272 7 HPFS/NTFS/exFAT /dev/sda3 48959486 125044735 38042625 5 Extended /dev/sda5 48959488 125044735 38042624 83 Linux sda1 --/ Windows Recovery sda2 --/ Windows 7 sda3/5 --/ Ubuntu root [ / ] Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc0ee6a69 Device Boot Start End Blocks Id System /dev/sdb1 1024208894 1953523711 464657409 5 Extended /dev/sdb3 * 2048 1024206847 512102400 7 HPFS/NTFS/exFAT /dev/sdb5 1024208896 1939851263 457821184 83 Linux /dev/sdb6 1939853312 1953523711 6835200 82 Linux swap / Solaris sdb3 --/ Partition for Steam games, etc. sdb5 --/ Ubuntu Home [ /home ] sdb6 --/ Ubuntu Swap Partition table entries are not in disk order Disk /dev/sdc: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x292eee23 Device Boot Start End Blocks Id System /dev/sdc1 2048 625141759 312569856 7 HPFS/NTFS/exFAT sdc1 --/ Generic backup I also used a Boot Script that other users suggested, so that I can give more details on my partitions and also where Grub is located... ============================= Boot Info Summary: =============================== => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos5)/boot/grub on this drive. => Grub2 (v1.99) is installed in the MBR of /dev/sdb and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos5)/boot/grub on this drive. => Windows is installed in the MBR of /dev/sdc. Now that is weird... Why would Grub2 be installed on both my SSD and HDD? Even weirder is why is Windows on the MBR of my backup hard drive? Nothing I did should have done that... Anyway, here is the entire Output from that script... PASTEBIN So, to summarize what I need: How can I fix my setup so grub loads on startup? How can I clean my partitions to remove unnecessary grubs? What did I do wrong so that I don't do something so daft again? Thank you so much for reading, and I hope you can help me. I've been trying to have a successful setup since Friday, and I'm almost at the point that I'm really tempted to throw my computer out the window due to my frustration.

  After several minutes(I do not know how many) there is no internet connection on my laptop via Wi-Fi.Ubuntu doesn't show any kind of message that my WiFi was disconnected neither there is a signal drop,but suddenly Firefox stops connecting to web pages.I checked my modem/router and it seems that it is working fine.I tried also to reboot the WiFi device and nothing happens.The only thing that it makes it work again is a reboot of the system and if I do not want to do a reboot then I am enforced to connect to the Internet using Ethernet cable.Does anybody know what is happening? ## Some Hardware info that might be helpful ## el10780@ThinkPad-W520:~$ sudo lshw -class network *-network description: Ethernet interface product: 82579LM Gigabit Network Connection vendor: Intel Corporation physical id: 19 bus info: pci@0000:00:19.0 logical name: eth0 version: 04 serial: f0:de:f1:f1:be:10 size: 100Mbit/s capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: pm msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000e driverversion=1.5.1-k duplex=full firmware=0.13-3 ip=192.168.0.10 latency=0 link=yes multicast=yes port=twisted pair speed=100Mbit/s resources: irq:50 memory:f3a00000-f3a1ffff memory:f3a2b000-f3a2bfff ioport:6080(size=32) *-network description: Wireless interface product: Centrino Advanced-N + WiMAX 6250 vendor: Intel Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: wlan0 version: 5e serial: 64:80:99:63:14:74 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.2.0-26-generic firmware=41.28.5.1 build 33926 ip=192.168.0.6 latency=0 link=yes multicast=yes wireless=IEEE 802.11abgn resources: irq:52 memory:f3900000-f3901fff *-network description: Ethernet interface physical id: 1 bus info: usb@2:1.3 logical name: wmx0 serial: 00:1d:e1:53:b2:e8 capabilities: ethernet physical configuration: driver=i2400m firmware=i6050-fw-usb-1.5.sbcf link=no el10780@ThinkPad-W520:~$ lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:16.3 Serial controller: Intel Corporation 6 Series/C200 Series Chipset Family KT Controller (rev 04) 00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04) 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b4) 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b4) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b4) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b4) 00:1c.6 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 7 (rev b4) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation QM67 Express Chipset Family LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 04) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 04) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [Quadro 1000M] (rev a1) 03:00.0 Network controller: Intel Corporation Centrino Advanced-N + WiMAX 6250 (rev 5e) 0d:00.0 System peripheral: Ricoh Co Ltd Device e823 (rev 08) 0d:00.3 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 PCIe IEEE 1394 Controller (rev 04) 0e:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04) el10780@ThinkPad-W520:~$ rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: tpacpi_bluetooth_sw: Bluetooth Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no 3: i2400m-usb:2-1.3:1.0: WiMAX Soft blocked: yes Hard blocked: no The weirdest thing is this screenshot which I took after running the **Additional Drivers** program.I mean I have a NVidia Quadro 1000M and my Intel Centrino WiFi Card and this shows that there are not proprietay drivers for my system. http://imageshack.us/photo/my-images/268/screenshotfrom201207062.png/

• SPTI problem with Mode Select

  - by Bob Murphy

  I'm running into a problem in which an attempt to do a "Mode Select" SCSI command using SPTI is returning an error status of 0x02 ("Check Condition"), and hope someone here might have some tips or suggestions. The code in question is intended to work with at a custom SCSI device. I wrote the original support for it using ASPI under WinXP, and am converting it to work with SPTI under 64-bit Windows 7. Here's the problematic code - and what's happening is, sptwb.spt.ScsiStatus is 2, which is a "Check Condition" error. Unfortunately, the device in question doesn't return useful information when you do a "Request Sense" after this problem occurs, so that's no help. void MSSModeSelect(const ModeSelectRequestPacket& inRequest, StatusResponsePacket& outResponse) { IPC_LOG("MSSModeSelect(): PathID=%d, TargetID=%d, LUN=%d", inRequest.m_Device.m_PathId, inRequest.m_Device.m_TargetId, inRequest.m_Device.m_Lun); int adapterIndex = inRequest.m_Device.m_PathId; HANDLE adapterHandle = prvOpenScsiAdapter(inRequest.m_Device.m_PathId); if (adapterHandle == INVALID_HANDLE_VALUE) { outResponse.m_Status = eScsiAdapterErr; return; } SCSI_PASS_THROUGH_WITH_BUFFERS sptwb; memset(&sptwb, 0, sizeof(sptwb)); #define MODESELECT_BUF_SIZE 32 sptwb.spt.Length = sizeof(SCSI_PASS_THROUGH); sptwb.spt.PathId = inRequest.m_Device.m_PathId; sptwb.spt.TargetId = inRequest.m_Device.m_TargetId; sptwb.spt.Lun = inRequest.m_Device.m_Lun; sptwb.spt.CdbLength = CDB6GENERIC_LENGTH; sptwb.spt.SenseInfoLength = 0; sptwb.spt.DataIn = SCSI_IOCTL_DATA_IN; sptwb.spt.DataTransferLength = MODESELECT_BUF_SIZE; sptwb.spt.TimeOutValue = 2; sptwb.spt.DataBufferOffset = offsetof(SCSI_PASS_THROUGH_WITH_BUFFERS,ucDataBuf); sptwb.spt.Cdb[0] = SCSIOP_MODE_SELECT; sptwb.spt.Cdb[4] = MODESELECT_BUF_SIZE; DWORD length = offsetof(SCSI_PASS_THROUGH_WITH_BUFFERS,ucDataBuf) + sptwb.spt.DataTransferLength; memset(sptwb.ucDataBuf, 0, sizeof(sptwb.ucDataBuf)); sptwb.ucDataBuf[2] = 0x10; sptwb.ucDataBuf[16] = (BYTE)0x01; ULONG bytesReturned = 0; BOOL okay = DeviceIoControl(adapterHandle, IOCTL_SCSI_PASS_THROUGH, &sptwb, sizeof(SCSI_PASS_THROUGH), &sptwb, length, &bytesReturned, FALSE); DWORD gle = GetLastError(); IPC_LOG(" DeviceIoControl() %s", okay ? "worked" : "failed"); if (okay) { outResponse.m_Status = (sptwb.spt.ScsiStatus == 0) ? eOk : ePrinterStatusErr; } else { outResponse.m_Status = eScsiPermissionsErr; } CloseHandle(adapterHandle); } A few more remarks, for what it's worth: This is derived from some old ASPI code that does the "Mode Select" flawlessly. This routine opens \\.\SCSI<whatever> at the beginning, via prvOpenScsiAdapter(), and closes the handle at the end. All the other routines for dealing with the device do the same thing, including the routine to do "Reserve Unit". Is this a good idea under SPTI, or should the call to "Reserve Unit" leave the handle open, so this routine and others in the sequence can use the same handle? This uses the IOCTL_SCSI_PASS_THROUGH. Should "Mode Select" use IOCTL_SCSI_PASS_THROUGH_DIRECT instead? Thanks in advance - any help will be greatly appreciated.

• 3 Incredibly Useful Projects to jump-start your Kinect Development.

  - by mbcrump

  I’ve been playing with the Kinect SDK Beta for the past few days and have noticed a few projects on CodePlex worth checking out. I decided to blog about them to help spread awareness. If you want to learn more about Kinect SDK then you check out my”Busy Developer’s Guide to the Kinect SDK Beta”. Let’s get started:   KinectContrib is a set of VS2010 Templates that will help you get started building a Kinect project very quickly. Once you have it installed you will have the option to select the following Templates: KinectDepth KinectSkeleton KinectVideo Please note that KinectContrib requires the Kinect for Windows SDK beta to be installed. Kinect Templates after installing the Template Pack. The reference to Microsoft.Research.Kinect is added automatically.  Here is a sample of the code for the MainWindow.xaml in the “Video” template: <Window x:Class="KinectVideoApplication1.MainWindow" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="480" Width="640"> <Grid> <Image Name="videoImage"/> </Grid> </Window> and MainWindow.xaml.cs using System; using System.Windows; using System.Windows.Media; using System.Windows.Media.Imaging; using Microsoft.Research.Kinect.Nui; namespace KinectVideoApplication1 { public partial class MainWindow : Window { //Instantiate the Kinect runtime. Required to initialize the device. //IMPORTANT NOTE: You can pass the device ID here, in case more than one Kinect device is connected. Runtime runtime = new Runtime(); public MainWindow() { InitializeComponent(); //Runtime initialization is handled when the window is opened. When the window //is closed, the runtime MUST be unitialized. this.Loaded += new RoutedEventHandler(MainWindow_Loaded); this.Unloaded += new RoutedEventHandler(MainWindow_Unloaded); //Handle the content obtained from the video camera, once received. runtime.VideoFrameReady += new EventHandler<Microsoft.Research.Kinect.Nui.ImageFrameReadyEventArgs>(runtime_VideoFrameReady); } void MainWindow_Unloaded(object sender, RoutedEventArgs e) { runtime.Uninitialize(); } void MainWindow_Loaded(object sender, RoutedEventArgs e) { //Since only a color video stream is needed, RuntimeOptions.UseColor is used. runtime.Initialize(Microsoft.Research.Kinect.Nui.RuntimeOptions.UseColor); //You can adjust the resolution here. runtime.VideoStream.Open(ImageStreamType.Video, 2, ImageResolution.Resolution640x480, ImageType.Color); } void runtime_VideoFrameReady(object sender, Microsoft.Research.Kinect.Nui.ImageFrameReadyEventArgs e) { PlanarImage image = e.ImageFrame.Image; BitmapSource source = BitmapSource.Create(image.Width, image.Height, 96, 96, PixelFormats.Bgr32, null, image.Bits, image.Width * image.BytesPerPixel); videoImage.Source = source; } } } You will find this template pack is very handy especially for those new to Kinect Development.   Next up is The Coding4Fun Kinect Toolkit which contains extension methods and a WPF control to help you develop with the Kinect SDK. After downloading the package simply add a reference to the .dll using either the WPF or WinForms version. Now you will have access to several methods that can help you save an image: (for example) For a full list of extension methods and properties, please visit the site at http://c4fkinect.codeplex.com/. Kinductor – This is a great application for just learning how to use the Kinect SDK. The project uses MVVM Light and is a great start for those looking how to structure their first Kinect Application. Conclusion: Things are already getting easier for those working with the Kinect SDK. I imagine that after a few more months we will see the SDK go out of beta and allow commercial applications to run using it. I am very excited and hope that you continue reading my blog for more Kinect, WPF and Silverlight news.  Subscribe to my feed

• Internet of Things Becoming Reality

  - by kristin.jellison

  The Internet of Things is not just on the radar—it’s becoming a reality. A globally connected continuum of devices and objects will unleash untold possibilities for businesses and the people they touch. But the “things” are only a small part of a much larger, integrated architecture. A great example of this comes from the healthcare industry. Imagine an expectant mother who needs to watch her blood pressure. She lives in a mountain village 100 miles away from medical attention. Luckily, she can use a small “wearable” device to monitor her status and wirelessly transmit the information to a healthcare hub in her village. Now, say the healthcare hub identifies that the expectant mother’s blood pressure is dangerously high. It sends a real-time alert to the patient’s wearable device, advising her to contact her doctor. It also pushes an alert with the patient’s historical data to the doctor’s tablet PC. He inserts a smart security card into the tablet to verify his identity. This ensures that only the right people have access to the patient’s data. Then, comparing the new data with the patient’s medical history, the doctor decides she needs urgent medical attention. GPS tracking devices on ambulances in the field identify and dispatch the closest one available. An alert also goes to the closest hospital with the necessary facilities. It sends real-time information on her condition directly from the ambulance. So when she arrives, they already have a treatment plan in place to ensure she gets the right care. The Internet of Things makes a huge difference for the patient. She receives personalized and responsive healthcare. But this technology also helps the businesses involved. The healthcare provider achieves a competitive advantage in its services. The hospital benefits from cost savings through more accurate treatment and better application of services. All of this, in turn, translates into savings on insurance claims. This is an ideal scenario for the Internet of Things—when all the devices integrate easily and when the relevant organizations have all the right systems in place. But in reality, that can be difficult to achieve. Core design principles are required to make the whole system work. Open standards allow these systems to talk to each other. Integrated security protects personal, financial, commercial and regulatory information. A reliable and highly available systems infrastructure is necessary to keep these systems running 24/7. If this system were just made up of separate components, it would be prohibitively complex and expensive for almost any organization. The solution is integration, and Oracle is leading the way. We’re developing converged solutions, not just from device to datacenter, but across devices, utilizing the Java platform, and through data acquisition and management, integration, analytics, security and decision-making. The Internet of Things (IoT) requires the predictable action and interaction of a potentially endless number of components. It’s in that convergence that the true value of the Internet of Things emerges. Partners who take the comprehensive view and choose to engage with the Internet of Things as a fully integrated platform stand to gain the most from the Internet of Things’ many opportunities. To discover what else Oracle is doing to connect the world, read about Oracle’s Internet of Things Platform. Learn how you can get involved as a partner by checking out the Oracle Java Knowledge Zone. Best regards, David Hicks

• A .NET Developers day with the iPad.

  - by mbcrump

  The Apple iPad is currently getting a lot of buzz because of the app store, the book store and of course iTunes. I had the chance to play with one and this is what I have learned about the device. Let’s get this out of the way first, the iPad is awesome. It is the device for media consumption and casual web browsing. But how does it measure up to those of us with .NET on our brains all days. Let’s find out… Main Screen – you can customize everything on this page. I guess I should replace that image with a C# or VS logo. Its pretty standard stuff if you have an iPhone.   Programming Books If you have a subscription to Safari Books Online, then you are in luck, its very easy to read the books on the iPad. Just fire up Safari web browser and goto the Safari Books Online. The biggest benefit that I can see with the iPad is the ability to read books wherever and not have to worry about purchasing books that I already have the .PDF for. Below is a sample from Code Complete 2nd Edition. Below is a PDF of the ECMA-334 C# Language Specification. As you can see its very readable and you should have no problem reading actual code.   Example of Code shown below: It is however easier to read the PDF and store them with a 3rd party PDF reader. I have seen several for .99 cents or less. You can however switch the screen to vertical to get more viewing space as shown below: I was disappointed with the iBooks application. I could not find a single .NET programming book anywhere. I was able to download the excellent sci-fi book “A memory of Wind” for free though. If I just overlooked them, then please email me with the names and titles. I couldn’t even find a technology category in the categories list. Web Surfing – Technical Sites Below is an example of my site in Safari. The code is very readable and the experience was identical to viewing it in Firefox. I tried multiple programming site and the pages looked great except those that used flash and of course it did not display on those pages.   News Apps - Technical Content The standard NY Times and USA Today looked great, but the Technical Content was lacking. It would probably be better to use Google Reader for online technical news.     YouTube Videos – Technical Content  Since its YouTube, we already know that a lot of technical content exist and it plays great on the iPad. I watched several programming videos and could clearly see the code being written. Taking Technical Notes The iPad comes with a great notepad for taking notes. I found that it was easy to take notes regarding projects that I am currently working on.   Calendar The calendar that ships with the iPad is great for organizing. You can setup exchange server or manually enter the information. Pretty standard stuff.    Random Applications that I like: TweetDeck.   and Adobe Ideas. Adobe Ideas is kinda like SketchFlow except you use your finger to mock up the sketches.  Don’t forget that the iPad is great for any type of podcasting. That pretty much sums it up, I would definitely recommend this device as it will only get better. I believe the iOS4 comes out on the 24th and the iPad will only get more and more apps. You could save a few bucks by waiting for the 2nd generation, but that’s a call that only you can make.

• Ops Center 12c - Update - Provisioning Solaris on x86 Using a Card-Based NIC

  - by scottdickson

  Last week, I posted a blog describing how to use Ops Center to provision Solaris over the network via a NIC on a card rather than the built-in NIC.  Really, that was all about how to install Solaris on a SPARC system.  This week, we'll look at how to do the same thing for an x86-based server. Really, the overall process is exactly the same, at least for Solaris 11, with only minor updates. We will focus on Solaris 11 for this blog.  Once I verify that the same approach works for Solaris 10, I will provide another update. Booting Solaris 11 on x86 Just as before, in order to configure the server for network boot across a card-based NIC, it is necessary to declare the asset to associate the additional MACs with the server.  You likely will need to access the server console via the ILOM to figure out the MAC and to get a good idea of the network instance number.  The simplest way to find both of these is to start a network boot using the desired NIC and see where it appears in the list of network interfaces and what MAC is used when it tries to boot.  Go to the ILOM for the server.  Reset the server and start the console.  When the BIOS loads, select the boot menu, usually with Ctrl-P.  This will give you a menu of devices to boot from, including all of the NICs.  Select the NIC you want to boot from.  Its position in the list is a good indication of what network number Solaris will give the device. In this case, we want to boot from the 5th interface (GB_4, net4).  Pick it and start the boot processes.  When it starts to boot, you will see the MAC address for the interface Once you have the network instance and the MAC, go through the same process of declaring the asset as in the SPARC case.  This associates the additional network interface with the server.. Creating an OS Provisioning Plan The simplest way to do the boot via an alternate interface on an x86 system is to do a manual boot.  Update the OS provisioning profile as in the SPARC case to reflect the fact that we are booting from a different interface.  Update, in this case, the network boot device to be GB_4/net4, or the device corresponding to your network instance number.  Configure the profile to support manual network boot by checking the box for manual boot in the OS Provisioning profile. Booting the System Once you have created a profile and plan to support booting from the additional NIC, we are ready to install the server. Again, from the ILOM, reset the system and start the console.  When the BIOS loads, select boot from the Boot Menu as above.  Select the network interface from the list as before and start the boot process.  When the grub bootloader loads, the default boot image is the Solaris Text Installer.  On the grub menu, select Automated Installer and Ops Center takes over from there. Lessons The key lesson from all of this is that Ops Center is a valuable tool for provisioning servers whether they are connected via built-in network interfaces or via high-speed NICs on cards.  This is great news for modern datacenters using converged network infrastructures.  The process works for both SPARC and x86 Solaris installations.  And it's easy and repeatable.

• Memory is full with vertex buffer

  - by Christian Frantz

  I'm having a pretty strange problem that I didn't think I'd run into. I was able to store a 50x50 grid in one vertex buffer finally, in hopes of better performance. Before I had each cube have an individual vertex buffer and with 4 50x50 grids, this slowed down my game tremendously. But it still ran. With 4 50x50 grids with my new code, that's only 4 vertex buffers. With the 4 vertex buffers, I get a memory error. When I load the game with 1 grid, it takes forever to load and with my previous version, it started up right away. So I don't know if I'm storing chunks wrong or what but it stumped me -.- for (int x = 0; x < 50; x++) { for (int z = 0; z < 50; z++) { for (int y = 0; y <= map[x, z]; y++) { SetUpVertices(); SetUpIndices(); cubes.Add(new Cube(device, new Vector3(x, map[x, z] - y, z), grass)); } } } vertexBuffer = new VertexBuffer(device, typeof(VertexPositionTexture), vertices.Count(), BufferUsage.WriteOnly); vertexBuffer.SetData<VertexPositionTexture>(vertices.ToArray()); indexBuffer = new IndexBuffer(device, typeof(short), indices.Count(), BufferUsage.WriteOnly); indexBuffer.SetData(indices.ToArray()); Thats how theyre stored. The array I'm reading from is a byte array which defines the coordinates of my map. Now with my old version, I used the same loading from an array so that hasn't changed. The only difference is the one vertex buffer instead of 2500 for a 50x50 grid. cubes is just a normal list that holds all my cubes for the vertex buffer. Another thing that just came to mind would be my draw calls. If I'm setting an effect for each cube in my cube list, that's probably going to take a lot of memory. How can I avoid doing this? I need the foreach method to set my cubes to the right position foreach (Cube block in cube.cubes) { effect.VertexColorEnabled = false; effect.TextureEnabled = true; Matrix center = Matrix.CreateTranslation(new Vector3(-0.5f, -0.5f, -0.5f)); Matrix scale = Matrix.CreateScale(1f); Matrix translate = Matrix.CreateTranslation(block.cubePosition); effect.World = center * scale * translate; effect.View = cam.view; effect.Projection = cam.proj; effect.FogEnabled = false; effect.FogColor = Color.CornflowerBlue.ToVector3(); effect.FogStart = 1.0f; effect.FogEnd = 50.0f; cube.Draw(effect); noc++; }
