• My linux server takes more than an hour to boot. Suggestions?

  - by jamieb

  I am building a CentOS 5.4 system that boots off a compact flash card using a card reader that emulates an IDE drive. It literally takes about an hour to boot. The ultra-slow part occurs when Grub is loading the kernel. Once that's done, the rest of the boot process only takes about a minute to get to a login prompt. Does anyone have any suggestions? I suspect that it may have to do with UDMA. Everything IDE-related in my BIOS seems to checkout. The read performance hdparm is telling me 1.77 MB/s. Ouch! (But even at that rate, it still shouldn't take an hour to decompress and load the kernel) [root@server ~]# hdparm -tT /dev/hdc /dev/hdc: Timing cached reads: 2444 MB in 2.00 seconds = 1222.04 MB/sec Timing buffered disk reads: 6 MB in 3.39 seconds = 1.77 MB/sec Trying to enable DMA is a no-go though: [root@server ~]# hdparm -d1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) Here's some command outputs that might help: System [root@server ~]# uname -a Linux server.localdomain 2.6.18-164.el5xen #1 SMP Thu Sep 3 04:47:32 EDT 2009 i686 i686 i386 GNU/Linux PCI info: [root@server ~]# lspci -v 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) Subsystem: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation 82945G/GZ Integrated Graphics Controller Flags: bus master, fast devsel, latency 0, IRQ 10 Memory at fdf00000 (32-bit, non-prefetchable) [size=512K] I/O ports at ff00 [size=8] Memory at d0000000 (32-bit, prefetchable) [size=256M] Memory at fdf80000 (32-bit, non-prefetchable) [size=256K] Capabilities: [90] Message Signalled Interrupts: 64bit- Queue=0/0 Enable- Capabilities: [d0] Power Management version 2 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 Flags: bus master, medium devsel, latency 0, IRQ 16 I/O ports at fe00 [size=32] 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 Flags: bus master, medium devsel, latency 0, IRQ 17 I/O ports at fd00 [size=32] 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 Flags: bus master, medium devsel, latency 0, IRQ 18 I/O ports at fc00 [size=32] 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 Flags: bus master, medium devsel, latency 0, IRQ 19 I/O ports at fb00 [size=32] 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) (prog-if 20 [EHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller Flags: bus master, medium devsel, latency 0, IRQ 16 Memory at fdfff000 (32-bit, non-prefetchable) [size=1K] Capabilities: [50] Power Management version 2 Capabilities: [58] Debug port 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) (prog-if 01 [Subtractive decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=01, subordinate=01, sec-latency=32 I/O behind bridge: 0000d000-0000dfff Memory behind bridge: fde00000-fdefffff Prefetchable memory behind bridge: 00000000fdd00000-00000000fdd00000 Capabilities: [50] #0d [0000] 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) Subsystem: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge Flags: bus master, medium devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) (prog-if 80 [Master]) Subsystem: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 17 I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at f800 [size=16] Capabilities: [70] Power Management version 2 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) Subsystem: Intel Corporation 82801G (ICH7 Family) SMBus Controller Flags: medium devsel, IRQ 17 I/O ports at 0500 [size=32] 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Acer LCD says "no signal"

  - by Ken

  I have an Acer 24" LCD (model "AL2423WDR") that's about 3 years old. It worked perfectly for most of its lifetime so far. Recently it started giving problems. When I turn it on, it either says "no signal" on the display, or the power light goes yellow (as if in power-saving mode). This happens with both DVI and VGA (both of which worked fine before), and stranger still, the 4 buttons on the front, for accessing the on-screen menus, don't do anything. I've also tried different computer hardware and software (PC/Mac, Linux/MacOS), but nothing has worked. I've tried power-cycling it (with both the power button and the power switch), and also unplugging it entirely. The nonworking buttons suggest to me an issue with the firmware. I found a place on Acer's website that says I can send it in to have it fixed, at my expense, but I'll avoid that if I can. Is there a way to fully reset it manually? Or is there something else I can try?

• Keyboard lights sometimes stay on after PC is powered off. Why?

  - by Vilx-

  Sometimes when I power off my PC some lights on the keyboard stay on. It's pretty random which ones, though I suspect it has something to do with what lights were on just before the shutdown (if I vigorously follow that they are all off while the PC is shutting down then they stay off). Not that this would change anything, but it is annoying. Why does this happen and how can I avoid it? Added: I know that I can turn off the power completely to my computer and it will go off. That's not the point. Actually, I even want my keyboard to have power, because I use it to turn on my computer (the power button on the case is difficult to reach). I just want the lights to go off. Or at least understand why this happens. Oh, and it's a PS2 keyboard.

• dual boot preinstalled windows 8 laptop with windows 7

  - by sarathi

  I am having a hard disk in gpt partition style and Windows 8 is pre-installed in uefi mode. While trying to dual boot using usb bootable disk(using rufus,gpt partition style,fat32),it displays "Windows is loading files", then while displaying "Starting Windows" it hangs. So, I tried to install it inside Windows using setup.exe. Everything was running fine, but when it gets self restarted again, it got stuck at "Starting Windows". When restarted in Windows 8, it showed a htm file stating that "Windows cannot be installed on a computer using battery power. If the battery runs out of power during the installation, you might lose data. To continue the installation, plug in the computer's power adapter." I am sure that power adapter is connected. I Googled a lot on this, but I didn't get solution.

• Dell XPS 17 Laptop USB SS Ports don't work until machine rebooted

  - by Matt

  I have a new Dell XPS 17 laptop and have an issue that the two USB SS ports on the rear of the machine are not recognising anything when I start-up. Have tried mouse, keyboard, headset, USB display. If I plug a USB hub in the power light on the hub lights (presume this is hard-wired) but a mouse plugged into the hub does not light up. If I restart the pc the ports work fine. Also the other two USB ports work fine all the time. I have switched off the power saving setting on the device manager (Power managementAllow the computer to turn off this device to save power) and also in the advanced power settings (USB Settings USB Selective suspend setting:disabled) I have also disabled USB powershare in the BIOS (not sure what this actually does!) This is becoming very annoying having to restart the machine every day before I can start work Running Win 7 Pro x64 EDIT: I have found that setting USB Emulation to Disabled has helped the devices to be recognised during start up but they keep dropping out completely when in use EDIT 2: I contacted Dell about this issue who told me to update the BIOS driver, when I asked if I should downgrade from the factory installed A13 to the A12 posted on the dell website they said no. However there is now an A14 available on the website has anyone tried this?

• How to get Windows Server 2008 VM to use multiple cores

  - by David Fraser

  I have a Windows Server 2008 machine running in VirtualBox. On initial installation, only one processor was made available, but now I want to run it as a multiprocessor machine. I have made all four cores available in the VirtualBox settings (as well as enabling VT-x/AMD-V and Nested Paging), but Task Manager still only shows one CPU. However, the four CPU cores are visible in Device Manager under Processors. In the event log on startup, I can see the following relevant events: EventLog.6009 Microsoft (R) Windows (R) 6.00.6002 Service Pack 2 Multiprocessor Free Kernel-Processor-Power.4 Processor 0 exposes the following: 1 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) How can I make this system actually boot up as a multiprocessor machine?

• Windows 7 boot problem on a Lenovo Thinkpad Z61m 9450HAG

  - by Matt Taylor

  I recently did a full upgrade of Windows 7 on my Thinkpad. Everything worked fine after up until the second reboot (the first reboot after some updates installed worked OK). At second reboot time the system would just black screen before the Windows logo appears. Disk/wireless/power/battery lights are all lit and the disk light is active (flickering). However, if I remove my battery and boot with just power it boots fine and quickly, and everything is OK. Any help on why this won't boot with battery plugged in is greatly appreciated. I need to take this battery out on the road/trains, etc. A little more detail on this story. The battery I had inserted when doing the (failed) boot was a long life battery. I have not tried inserting this battery when Windows is logged in. I have another (normal life) battery that I have charged up within Windows. It has just got to 100% and I am about to reboot with it in. I am using the Lenovo power manager to diagnose the battery - all seems OK. I will report back shortly as to the outcome. OK, so I chose the reboot option from within Windows, the machine seemed to shutdown okay, but then stalled. It didn't turn off completely and didn't reboot, but just sat, with the fan humming, somewhere in between! I had to hold the power button in for a few seconds until the fan stopped and then hit the power button again to boot the machine from fresh. One good thing, with this battery (the normal one) it booted into Windows 7 the first time with a battery! So, now I have rebooting issues. I have 3 errors in the event log: A timeout was reached (30000 milliseconds) while waiting for the lxdxCATSCustConnectService service to connect. The lxdxCATSCustConnectService service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. The following boot-start or system-start driver(s) failed to load: cdrom Any thoughts?

• When machine is turned on, only the fan runs

  - by Gopal

  Hi, I have an issue slightly similar to this one posted here, http://superuser.com/questions/127016/troubleshooting-monitor-never-turns-on-system-fans-running-dvd-rom-does-not-op My configuration is as follows: EPOX 9NPA+ Ultra motherboard AMD Athlon 64 CPU Corsair 2 x 1GB PC3200 DDR RAM 1 DVD RW drive and 1 CD ROM Drive SATA 250 GB Hard drive 400W Power supply EVGA 256MB graphics card I have had this configuration for about four years. Last month, I started having issues in starting the machine. It wouldn't start when I press the ON button in the front of the case. So I used to pull out the power cord and plug it back in and then switch on in the front, and it used to work fine. And then one fine day, when I plugged in the power cord at the back, even without switching on the power-on button at the front, I saw that the fan at the back was running. So I opened the system. Then I could see that all the fans inside were running. I replaced the power supply. No luck there. Then I replaced the CMOS battery. Again nothing improved. Even when I removed all the cards and memory, I still get one short beep. That's it. Any idea how to proceed on this? Anything else could be checked? I want to confirm if this is a motherboard failure, before proceeding to replace it.

• Compaq motherboard CQ60 AMD - nvidia chipsed graphic problem

  - by Dritan

  Hi! It nice to have read that you solved this problem this way. I have 2 laptops Compaq CQ60 AMD Athlon with Nvidia graphic cards. the first one is new, when i press power button, it lights up only the ON led in front and nothing else, no fan working, blank screen, no beep.. I don't know what may be the problem. When I put on power adaptor, it lights up only the side power led near dhe power adapter plug but it doesn't light up the front led one. the second one have this problem that it spins the fan, light power and On led, but it doesn't show nothing on the screen blank (even with external monitor). In this case it maybe this problem of the Nvida Graphic Chip and it may need a reflow. I have an hot air station, but I don't know if I should try this or the oven one. Please can you give me any suggestion what to do to solve this. I have read that the solution of the Oven method is just temporary,maximum of three months, do you have the same experience about this? Any suggestion is wellcome.

• New build won't boot: some fans turning, no beep or video

  - by Dave

  When my new system is powered up, the case fan and power supply fans turn fine. The CPU fan twitches, but never gets going. Although I've heard that with AMDs and Gigabyte motherboards that is not necessary a problem. Hard drive is spinning. However, there is absolutely no indication that anything else is happening. The motherboard, as far as I can tell, does not have an internal speaker, but I harvested one from another machine and plugged it in and still no beeps at all. The monitor screen stays black, on both the integrated VGA and DVI. This is a brand new build, and has never successfully booted. My parts are: AMD Athlon II X2 245 Regor 2.9GHz Socket AM3 65W Dual-Core Processor Model ADX245OCGQBOX - includes CPU cooler) GIGABYTE GA-MA785GPMT-UD2H AM3 AMD 785G HDMI Micro ATX AMD Motherboard - Retail G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL8D-4GBRM - Retail CORSAIR CMPSU-400CX 400W ATX12V V2.2 80 PLUS Certified Compatible with Core i7 Power Supply - Retail SAMSUNG Spinpoint F3 HD502HJ 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive COOLER MASTER Elite 341 RC-341C-KKN1-GP Black Steel MicroATX Mid Tower Computer Case - Retail I also have a DVD burner, but it acts the same whether that is plugged in or not. I'm using the on board video. What I've tried so far: I've switched power supplies, with no difference. I've tried different monitors (of which all are working on other machines) with no difference. I have tried putting it one memory module at a time, with no difference. I have tried the absolute minimum I can think of (power supply into motherboard, power button ONLY plugged into front panel, CPU fan plugged in), with no difference. I appreciate any ideas anyone might have. Do I need to RMA the motherboard? This is my first build, so there might be something obvious. I was very careful in assembly with static; I'm confident nothing was zapped during assembly.

• Windows only successfully wakes up from sleep mode about 2/3rds of the time.

  - by Macha

  On my Vista laptop, when it goes into sleep mode (for low power, or manually being put into sleep mode, it happens regardless of how), about 1 in 3 times it won't wake up properly from sleep mode, and just display a black screen. The only option is to hold the power button to turn it off by holding the power button, and turning it back on again. (And yes, I have moved the mouse, pressed keyboard buttons and stuff).

• How to get data from a borked Windows Home Server

  - by harhoo

  Yesterday we had a power surge, followed by a power outage. This left my WHS borked: powering on just gives to a flashing blue light (the led on the power supply also flashes green) - no fan or boot activity, nothing. I urgently needed some files off there in the short term (and the 500GB of photos, music, personal video etc in the long term) so I took the hard drive out and put it in my computer. The files and folders showed up, but I couldn't access them - clicking on an image gave an invalid image error in Picasa, I couldn't play MP3s etc. I changed the ownership and permissions of the files, still nothing. I booted in with a LiveCD, the same: files appear, but won't open. Is there anything else I can do? I'm now wondering if it was just the power cable that's broken, but if so, why can;t I access my files from the hard drive? If it is the power cable, and I replace that and the hard drive, will I have done any harm messing around with ownership and file permissions?

• Toshiba A205-5804 freezes when plugged in

  - by heron

  Well I have a Toshiba A205-5804 and the problem is that the screen freezes anytime I plug the pc into the external power supply, not as most of the computers having the same issue, my computer DOES freeze in safe mode, and I really can't bear this problem for much longer... It's not an overheating problem, the computer is not getting hot or anything related, I've already tried changing the AC adapter, booting only with AC and no battery, and also all of these suggestions: Try changing the following setting in the bios setup, under the 'Advanced' tab Dynamic CPU Frequency: Mode = Always Low (NOT DYNAMIC) My laptop has been running on AC power without a problem for 24hours, including many restarts, and when I went back to the original bios setting, the problem returned almost straight away. EDIT Other suggestions I found on the web from here and here: Set the power plan to high performance Set the power plan to "Minimal Power Management" (1 and 2 do conflict) Start - Control Panel - Device Manager -- Processor - disable one of two processors - reboot normally 4.Do this: Only plug battery into laptop Turn on the laptop and start Windows normally Plug AC adapter into laptop, the screen will freeze Leave the laptop the way it is for 12-24 hours After 12-24 hours, turn it off the hard way Once it is turned off, turn it back on. The laptop is working now. I have no idea of what can it be...

• My home router randomly disconnects me and I'm unable to reconnect to it

  - by Roy Tang

  It's happened a few times, I'm not sure how to diagnose/debug, so any advise would be appreciated. Symptons: sometimes the router will randomly disconnect; the connection icon on my desktop (wired to the router) gets that yellow "!" symbol that tells me my connection just went down. At this point I'm unable to ping the router. afterwards I try to reset the router by removing then reconnecting the power jack on the router side (this is the fastest way as I can't reset the power strip it's connected to without rebooting my desktop. the router has a reset thingy, but it's one of those things where i have to find a pin to stick into the hole, and when I get disconnected I usually need to get reconnected immediately so I just pull and put back the power jack), but even after that the connection has the same state. after the router reboots, if I try to connect to it using a wifi device like my ipad, the ipad prompts me for the wifi password even though it had already "remembered" all the settings for this router forever after i finally decide to reboot the power strip, and my desktop and the router boot up again, the connection returns to its normal state somewhat and i'm able to connect to it as normal using the desktop and wifi devices. What do I need to check the next time this happens so I can figure out the problem? Is it possibly because we've been using the power jack on the router as an easier way to reboot it? Should I be shopping around for a new router? If it helps, the router is a DLink DIR-300

• Holding off Windows 2000/3 Server in Shutdown

  We have a C# VS2010 application running on a Windows 2000 Server box (there is also a Windows 2003 Server box) as pretty much the only application running. We remove power from the box. There is a short duration battery (maybe 3 minutes of power) which then waits 10 seconds and then decides things are coming down and notifies Windows that it needs to shut down. Windows sends a CTRL_SHUTDOWN_EVENT event to the application which fields it and tries to keep Windows from going down for a while to let another computer which communicates with this one time to do some file work on the first computer. It does this by a timing loop and after the loop is over, it exits gracefully and the computer shuts down. Nice plan but it doesn't work. The application gets to maybe 20 seconds and the application is forcibly killed by Windows and Windows shuts down. At 90 seconds, the hardware firmware running the battery turns off power to the computer. I have tried searching to find out how to hold off Windows for a bit of time. I tried creating (it wasn't there) the HKEY_LOCAL_MACHINE subtree: \SYSTEM\CurrentControlSet\Control\WaitToKillAppTimeout registry key to 60000 but though it seemed to keep the popup from happening, Windows itself died at about the same amount of time -- we think without having the opportunity to shut itself down gracefully. Maybe the registry key worked but wasn't enough. Basically I have an "ill-mannered" application which is refusing to shut down (for the best of reasons) and without the registry key thing, Windows eventually shuts it down anyway and then shuts itself down. With the registry change, we think what is happening is that Windows doesn't shut down the application but Windows itself is killed suddenly without shutting down but power is still not pulled for about another minute, and then power is pulled. So maybe we have layers here. First there is how long the application tries to stay open. Then there is how long Windows is prepared to allow it to stay open. Then there is ... something... which kills windows. Then there is the power loss. Anyone have any ideas how we can get windows to stay open and in operation say to 70 seconds instead of about 20? Is our registry key right, but not enough? Is there some additional key we need to set to determine how long after windows is notified of a shutdown before it just kills itself? Thanks in advance.

• Battery notification always showing 'xx% remaining' with Windows 7 on an acer Aspire 5590

  - by dindeman

  My battery level always shows up as something like 55% remaining or 63% remaining ...etc despite that it is in fact charging. Additionally it doesn't go any further than 80% remaining even if I keep it in charge forever. This leads me to a side annoying effect which is that I cannot proceed to install Windows 7 Service Pack 1 as its installer requires the laptop to be plugged with a power cord. My laptop is plugged with the power cord but because of the above issue (it doesn't display anything else than the xx% remaining) Windows thinks that the laptop is using its battery and that the power cord is disconnected. I have installed the original acer ePower Management tool that let you configure the power scheme... etc, I was hoping that this would help me circumvent the 80% issue but it doesn't.

• Video adapter problem on new motherboard

  - by Dmitriy Matveev

  Something bad happened to my PC several days ago. I wasn't near my PC, so I have no idea about what happened it was just halted. When I tried to boot it was entering infinite loops of a few seconds power up (cpu, hdds, etc) and then power down. I've tried to boot the system with no additional components (that includes hdd, video, network adapters and even memory) connected and that didn't solved the problem, so I've made a decision that most likely it's either some a problem with power unit or with motherboard. I've tried to replace my power unit by another one (which was expected to be working) and the problem didn't resolved again. I've bought a new MB (ASUS P5KPL-AM SE) and tried to get it running with my old CPU and memory (I hope it's still alive). Since this MB include on-board video I've tried to run the PC without installation of mine video. The PC wasn't running and the BIOS was beeping one long signal following by two short (Does it means a video problem?). After that I've installed my video adapter to PCI-E slot and tried to boot the system again and the BIOS was beeping the same. I don't get it. I may expect some problem with CPU and/or memory since I don't know what happened to my PC (maybe some power failure or something different), but not with video and not with on-board video on newly bought MB. How can I understand what's wrong with my system now?

• Professional Scrum Developer (.NET) Training in London

  - by Martin Hinshelwood

  On the 26th - 30th July in Microsoft’s offices in London Adam Cogan from SSW will be presenting the first Professional Scrum Developer course in the UK. I will be teaching this course along side Adam and it is a fantastic experience. You are split into teams and go head-to-head to deliver units of potentially shippable work in four two hour sprints. The Professional Scrum Developer course is the only course endorsed by both Microsoft and Ken Schwaber and they have worked together very effectively in brining this course to fruition. This course is the brain child of Richard Hundhausen, a Microsoft Regional Director, and both Adam and I attending the Trainer Prep in Sydney when he was there earlier this year. He is a fantastic trainer and no matter where you do this course you can be safe in the knowledge that he has trained and vetted all of the teachers. A tools version of Ken if you will Find a course and register Download this syllabus Download the Scrum Guide What is the Professional Scrum Developer course all about? Professional Scrum Developer course is a unique and intensive five-day experience for software developers. The course guides teams on how to turn product requirements into potentially shippable increments of software using the Scrum framework, Visual Studio 2010, and modern software engineering practices. Attendees will work in self-organizing, self-managing teams using a common instance of Team Foundation Server 2010. Who should attend this course? This course is suitable for any member of a software development team – architect, programmer, database developer, tester, etc. Entire teams are encouraged to attend and experience the course together, but individuals are welcome too. Attendees will self-organize to form cross-functional Scrum teams. These teams require an aggregate of skills specific to the selected case study. Please see the last page of this document for specific details. Product Owners, ScrumMasters, and other stakeholders are welcome too, but keep in mind that everyone who attends will be expected to commit to work and pull their weight on a Scrum team. What should you know by the end of the course? Scrum will be experienced through a combination of lecture, demonstration, discussion, and hands-on exercises. Attendees will learn how to do Scrum correctly while being coached and critiqued by the instructor, in the following topic areas: Form effective teams Explore and understand legacy “Brownfield” architecture Define quality attributes, acceptance criteria, and “done” Create automated builds How to handle software hotfixes Verify that bugs are identified and eliminated Plan releases and sprints Estimate product backlog items Create and manage a sprint backlog Hold an effective sprint review Improve your process by using retrospectives Use emergent architecture to avoid technical debt Use Test Driven Development as a design tool Setup and leverage continuous integration Use Test Impact Analysis to decrease testing times Manage SQL Server development in an Agile way Use .NET and T-SQL refactoring effectively Build, deploy, and test SQL Server databases Create and manage test plans and cases Create, run, record, and play back manual tests Setup a branching strategy and branch code Write more maintainable code Identify and eliminate people and process dysfunctions Inspect and improve your team’s software development process What does the week look like? This course is a mix of lecture, demonstration, group discussion, simulation, and hands-on software development. The bulk of the course will be spent working as a team on a case study application delivering increments of new functionality in mini-sprints. Here is the week at a glance: Monday morning and most of the day Friday will be spent with the computers powered off, so you can focus on sharpening your game of Scrum and avoiding the common pitfalls when implementing it. The Sprints Timeboxing is a critical concept in Scrum as well as in this course. We expect each team and student to understand and obey all of the timeboxes. The timebox duration will always be clearly displayed during each activity. Expect the instructor to enforce it. Each of the ½ day sprints will roughly follow this schedule: Component Description Minutes Instruction Presentation and demonstration of new and relevant tools & practices 60 Sprint planning meeting Product owner presents backlog; each team commits to delivering functionality 10 Sprint planning meeting Each team determines how to build the functionality 10 The Sprint The team self-organizes and self-manages to complete their tasks 120 Sprint Review meeting Each team will present their increment of functionality to the other teams = 30 Sprint Retrospective A group retrospective meeting will be held to inspect and adapt 10 Each team is expected to self-organize and manage their own work during the sprint. Pairing is highly encouraged. The instructor/product owner will be available if there are questions or impediments, but will be hands-off by default. You should be prepared to communicate and work with your team members in order to achieve your sprint goal. If you have development-related questions or get stuck, your partner or team should be your first level of support. Module 1: INTRODUCTION This module provides a chance for the attendees to get to know the instructors as well as each other. The Professional Scrum Developer program, as well as the day by day agenda, will be explained. Finally, the Scrum team will be selected and assembled so that the forming, storming, norming, and performing can begin. Trainer and student introductions Professional Scrum Developer program Agenda Logistics Team formation Retrospective Module 2: SCRUMDAMENTALS This module provides a level-setting understanding of the Scrum framework including the roles, timeboxes, and artifacts. The team will then experience Scrum firsthand by simulating a multi-day sprint of product development, including planning, review, and retrospective meetings. Scrum overview Scrum roles Scrum timeboxes (ceremonies) Scrum artifacts Simulation Retrospective It’s required that you read Ken Schwaber’s Scrum Guide in preparation for this module and course. MODULE 3: IMPLEMENTING SCRUM IN VISUAL STUDIO 2010 This module demonstrates how to implement Scrum in Visual Studio 2010 using a Scrum process template*. The team will learn the mapping between the Scrum concepts and how they are implemented in the tool. After connecting to the shared Team Foundation Server, the team members will then return to the simulation – this time using Visual Studio to manage their product development. Mapping Scrum to Visual Studio 2010 User Story work items Task work items Bug work items Demonstration Simulation Retrospective Module 4: THE CASE STUDY In this module the team is introduced to their problem domain for the week. A kickoff meeting by the Product Owner (the instructor) will set the stage for the why and what that will take during the upcoming sprints. The team will then define the quality attributes of the project and their definition of “done.” The legacy application code will be downloaded, built, and explored, so that any bugs can be discovered and reported. Introduction to the case study Download the source code, build, and explore the application Define the quality attributes for the project Define “done” How to file effective bugs in Visual Studio 2010 Retrospective Module 5: HOTFIX This module drops the team directly into a Brownfield (legacy) experience by forcing them to analyze the existing application’s architecture and code in order to locate and fix the Product Owner’s high-priority bug(s). The team will learn best practices around finding, testing, fixing, validating, and closing a bug. How to use Architecture Explorer to visualize and explore Create a unit test to validate the existence of a bug Find and fix the bug Validate and close the bug Retrospective Module 6: PLANNING This short module introduces the team to release and sprint planning within Visual Studio 2010. The team will define and capture their goals as well as other important planning information. Release vs. Sprint planning Release planning and the Product Backlog Product Backlog prioritization Acceptance criteria and tests Sprint planning and the Sprint Backlog Creating and linking Sprint tasks Retrospective At this point the team will have the knowledge of Scrum, Visual Studio 2010, and the case study application to begin developing increments of potentially shippable functionality that meet their definition of done. Module 7: EMERGENT ARCHITECTURE This module introduces the architectural practices and tools a team can use to develop a valid design on which to develop new functionality. The teams will learn how Scrum supports good architecture and design practices. After the discussion, the teams will be presented with the product owner’s prioritized backlog so that they may select and commit to the functionality they can deliver in this sprint. Architecture and Scrum Emergent architecture Principles, patterns, and practices Visual Studio 2010 modeling tools UML and layer diagrams SPRINT 1 Retrospective Module 8: TEST DRIVEN DEVELOPMENT This module introduces Test Driven Development as a design tool and how to implement it using Visual Studio 2010. To maximize productivity and quality, a Scrum team should setup Continuous Integration to regularly build every team member’s code changes and run regression tests. Refactoring will also be defined and demonstrated in combination with Visual Studio’s Test Impact Analysis to efficiently re-run just those tests which were impacted by refactoring. Continuous integration Team Foundation Build Test Driven Development (TDD) Refactoring Test Impact Analysis SPRINT 2 Retrospective Module 9: AGILE DATABASE DEVELOPMENT This module lets the SQL Server database developers in on a little secret – they can be agile too. By using the database projects in Visual Studio 2010, the database developers can join the rest of the team. The students will see how to apply Agile database techniques within Visual Studio to support the SQL Server 2005/2008/2008R2 development lifecycle. Agile database development Visual Studio database projects Importing schema and scripts Building and deploying Generating data Unit testing SPRINT 3 Retrospective Module 10: SHIP IT Teams need to know that just because they like the functionality doesn’t mean the Product Owner will. This module revisits acceptance criteria as it pertains to acceptance testing. By refining acceptance criteria into manual test steps, team members can execute the tests, recording the results and reporting bugs in a number of ways. Manual tests will be defined and executed using the Microsoft Test Manager tool. As the Sprint completes and an increment of functionality is delivered, the team will also learn why and when they should create a branch of the codeline. Acceptance criteria Testing in Visual Studio 2010 Microsoft Test Manager Writing and running manual tests Branching SPRINT 4 Retrospective Module 11: OVERCOMING DYSFUNCTION This module introduces the many types of people, process, and tool dysfunctions that teams face in the real world. Many dysfunctions and scenarios will be identified, along with ideas and discussion for how a team might mitigate them. This module will enable you and your team to move toward independence and improve your game of Scrum when you depart class. Scrum-butts and flaccid Scrum Best practices working as a team Team challenges ScrumMaster challenges Product Owner challenges Stakeholder challenges Course Retrospective What will be expected of you and you team? This is a unique course in that it’s technically-focused, team-based, and employs timeboxes. It demands that the members of the teams self-organize and self-manage their own work to collaboratively develop increments of software. All attendees must commit to: Pay attention to all lectures and demonstrations Participate in team and group discussions Work collaboratively with other team members Obey the timebox for each activity Commit to work and do your best to deliver All teams should have these skills: Understanding of Scrum Familiarity with Visual Studio 201 C#, .NET 4.0 & ASP.NET 4.0 experience*  SQL Server 2008 development experience Software testing experience * Check with the instructor ahead of time for the exact technologies Self-organising teams Another unique attribute of this course is that it’s a technical training class being delivered to teams of developers, not pairs, and not individuals. Ideally, your actual software development team will attend the training to ensure that all necessary skills are covered. However, if you wish to attend an open enrolment course alone or with just a couple of colleagues, realize that you may be placed on a team with other attendees. The instructor will do his or her best to ensure that each team is cross-functional to tackle the case study, but there are no guarantees. You may be required to try a new role, learn a new skill, or pair with somebody unfamiliar to you. This is just good Scrum! Who should NOT take this course? Because of the nature of this course, as explained above, certain types of people should probably not attend this course: Students requiring command and control style instruction – there are no prescriptive/step-by-step (think traditional Microsoft Learning) labs in this course Students who are unwilling to work within a timebox Students who are unwilling to work collaboratively on a team Students who don’t have any skill in any of the software development disciplines Students who are unable to commit fully to their team – not only will this diminish the student’s learning experience, but it will also impact their team’s learning experience Find a course and register Download this syllabus Download the Scrum Guide Technorati Tags: Scrum,SSW,Pro Scrum Dev
