• Ubuntu 12.04 does not suspend with proprietary driver for Radeon 6800

  - by Mike

  I'm running Ubuntu 12.04 x86_64 (though these issues have existed in previous releases too) and have a Radeon 6800 graphics card. I've run into issues with the open-source driver (the system would randomly hang when shutting down) so I switched to the proprietary driver (I compiled it myself using these instructions), but I am having new problems now. The main issue is that when I go into sleep mode, about 50-75% of the time, the screen goes black but the monitor does not actually shut off, and I can hear that the fans/hard drive are not suspending either. I can't get the computer to wake up (Ctrl+Alt+F1,2,3,etc. does not work), and I always end up force shutting down with the power button. I'd really appreciate help! Here is some information that might be helpful: $ fglrxinfo display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.

• Introducing a (new) test method to a team

  - by Jon List

  A couple of months ago i was hired in a new job. (I'm fresh out of my Masters in software engineering) The company mainly consists of ERP consultants, but I was hired in their fairly small web department (6 developers), our main task is ERP/ecom integration (ERP-integrated web shops). The department is growing, and recently my manager asked me to start thinking about introducing tests to the team, i love a challenge, but frankly I'm a bit scared (I'm the least experience member of the team). Currently the method of testing is clicking around in the web shop and asking the customer if the products are there, if they look okay, and if orders are posted correctly to the ERP. We are getting a lot of support cases on previous projects, where a customer or a customer's customer have run into errors, which - i suppose - is why my manager wants more structured testing. Off the top of my head, I though of some (obvious?) improvements, like looking at the requirement specification, having an issue tracker, enabling team members to register their time on a "tests"-line on the budget, and to circulate tasks amongst members of the team. But as i see it we have three main challenges: general website testing. (javascript, C#, ASP.NET and CMS integration tests) (live) ERP integration testing (customers rarely want to pay for test environments). adopting a method in the team I like the responsibility, but I am afraid that I'm in a little bit over my head. I expect that my manager expects me to set up some kind of workshop for the team where I present some techniques and ideas and where we(the team) can find some solutions together. What I learned in school was mostly unit testing and program verification, not so much testing across multiple systems and applications. What I'm looking for here, is references/advice/pointers/anecdotes; anything that might help me to get smarter and to improve the current method of my team. Thanks!! (TL;DR: read the bold parts)

• How to go from Mainframe to the Cloud?

  - by Ruma Sanyal

  Running applications on IBM mainframes is expensive, complex, and hinders IT responsiveness. The high costs from frequent forced upgrades, long integration cycles, and complex operations infrastructures can only be alleviated by migrating away from a mainframe environment.  Further, data centers are planning for cloud enablement pinned on principles of operating at significantly lower cost, very low upfront investment, operating on commodity hardware and open, standards based systems, and decoupling of hardware, infrastructure software, and business applications. These operating principles are in direct contrast with the principles of operating businesses on mainframes. By utilizing technologies such as Oracle Tuxedo, Oracle Coherence, and Oracle GoldenGate, businesses are able to quickly and safely migrate away from their IBM mainframe environments. Further, running Oracle Tuxedo and Oracle Coherence on Oracle Exalogic, the first and only integrated cloud machine on the market, Oracle customers can not only run their applications on standards-based open systems, significantly cutting their time to market and costs, they can start their journey of cloud enabling their mainframe applications. Oracle Tuxedo re-hosting tools and techniques can provide automated migration coverage for more than 95% of mainframe application assets, at a fraction of the cost Oracle GoldenGate can migrate data from mainframe systems to open systems, eliminating risks associated with the data migration Oracle Coherence hosts transactional data in memory providing mainframe-like data performance and linear scalability Running Oracle software on top of Oracle Exalogic empowers customers to start their journey of cloud enabling their mainframe applications Join us in a series of events across the globe where you you'll learn how you can build your enterprise cloud and add tremendous value to your business. In addition, meet with Oracle experts and your peers to discuss best practices and see how successful organizations are lowering total cost of ownership and achieving rapid returns by moving to the cloud.

• Regulating how much to draw based on how much was drawn last frame.

  - by Mike Howard

  I have a 3D game world on an iPhone (limited graphics speed), and I'm already regulating whether I draw each shape on the screen based on it's size and distance from the camera. Something like... if (how_big_it_looks_from_the_camera > constant) then draw What I want to do now is also take into account how many shapes are being drawn, so that in busier areas of the game world I can draw less than I otherwise would. I tried to do this by dividing how_big_it_looks by the number of shapes that were drawn last frame (well, the square root of this but I'm simplifying - the problem is the same). if (how_big_it_looks / shapes_drawn > constant2) then draw But the check happens at the level of objects which represent many drawn shapes, and if an object containing many shapes is switched on, it increases shapes_drawn lots and switches itself back off the next frame. It flickers on and off. I tried keeping a kind of weighted average of previous values, by each frame doing something like shapes_drawn_recently = 0.9 * shapes_drawn_recently + 0.1 * shapes_just_drawn, but of course it only slows the flickering down because of the nature of the feedback loop. Is there a good way of solving this? My project is in Objective-C, but a general algorithm or pseudo-code is good too. Thanks.

• AMD FX CPU drivers/patch

  - by Mubeen Shahid

  I am using Ubuntu since 2009 on notebooks with Intel CPUs. However now, that I am using AMD's FX 6300, I am interested in knowing if there exists anything from Ubuntu (specifically any kernel enhancements/drivers/patches) for AMD's FX "family 15h" Piledrivers. Reason: I would like to have a kernel which uses the hardware to its full capacity, be able to use the latest instruction sets, for max. performance. I did some tests, started with compiling stable 3.9.7 on my 12.04 LTS box, and during compilation I choose processor vendor AMD (unchecked Intel/VIA/etc.), and when I started Ubuntu with this compiled kernel, in the section "System Settings - Additional Drivers" I found that, in addition to graphic card's drivers, there were AMD family 15h drivers also. However, I would prefer something in this regard tested/signed by Ubuntu developers. P.S: 1- the kernel that I have compiled has some issues with Nvidia graphics drivers, so I deleted kernel 3.9.7 and installed signed 3.8.xx from Ubuntu repositories. 2- incase if somebody is planning to advise me to install "AMD64", I am not talking about AMD64 (which is in fact for 64-bit platform).

• Novice prototyping a massive multiplayer webpage based gaming system

  - by Sean Hendlin

  I'm trying to build a website based game in which various pages of the site act as different areas of the game. I am wondering what you would recommended as a design structure. Which languages would be best if building what will hopefully becomes a massive system able to scale to massive amounts of users. I am wondering if and how various elements from differing languages could be meshed to interact with each other. For example could I use html5, javascript, and PHP? What about asp.net how might that factor in? I'm a newbie programmer but I've been working on this idea for years and I want to build it to reality. Your comments and suggestions are appreciated. P.S.: The game is not all graphics and animation (though flash like appearance and some animation would be nice). What I am thinking of is essentially a heavily gamified system of forms. And LOTS of data in many different categories cross referencing each-other. I'm not sure how to go about structuring the collection of data. Also while I know javascript can be used to process some functions, I'm wondering what sort of base system I would need to handle the server side processing of what I am expecting to be some pretty significant algorithm processing. That is to say I expect to have many many many functions and I'm not sure how to mange this using javascript. I feel like they would be forgotten, mixed up, disorganizes as they essentially only exist where they are coded. I guess I need to learn something of libraries? OK, Thank you! Is enough from me for now.

• Fn key sticks down

  - by Oli

  Just bought my significant other a shiny new Samsung Q330 13" netbook, stuck an OCZ Agility in it and installed Maverick. Just as a quick aside, this is a devastating combination. Graphics work perfectly and it cold-boots to desktop in about 7 seconds. Very quick. But (common to laptops) I've got a couple of problems. I'll start with the most problematic and start a new thread for the other. Like a lot of laptops, there is a Fn (function) modifier to allow some keys to have another purpose. When I tried to alter the brightness of the screen by tapping Fn+Down, it worked but kept on going until it was as dim as it could go. I tapped Fn+Up and it went to the other extreme. After that the entire keyboard ceases to work properly because the Fn modifier appears to be locked. Additionally, and as a direct side effect, I think, clicking on things doesn't result in a standard result. It's as if control is being held. A reboot is the only thing that seems to fix these problems. This isn't a problem if you don't touch the Fn key but as there are two of them on the keyboard, an accident is going to happen sooner than later, requiring a reboot (and probably some data loss). I don't have a lot of experience with laptops (I prefer my hulking great desktop) so this isn't my area of expertise. I'm open to all suggestions, even disabling the two Fn keys until we can find a better solution.

• Non-Obvious Topics to Learn for Game Development

  - by ashes999

  I've been writing games for around 10 years now (from QBasic to C# and everything in-between). I need to start stretching my skills into different areas. What are other, surprising topics I should read up on? Expected topics would include the usual suspects: Programming language of your choice Scripting language Source control Project management (or Agile) Graphics API Maybe some AI (A* path-finding?) Physics (projectile physics) Unit testing (automated testing) I'm looking for more esoteric topics; things that you don't expect to need to know, but if you do know them, they make a difference. This could include things like: Art skills (drawing, lighting, colouring, layout, etc.) Natural language processing The physics of sound (sound-waves, doppler effect, etc.) Personally, I feel that having technical art skills (eg. can make decent art-work if you can only come up with ideas; or, following Photoshop/GIMP tutorials) was the most beneficial for me. This is not intended to be an open-ended question; I'm looking for specific skills that helped you and you expect will continue to benefit you in the short- and long-term.

• CyanogenMod Updates; Rolls out Android 2.3 to the Less Fortunate

  - by ETC

  If you’re one of the less fortunate (namely those forgotten by their carrier when it comes to phone OS upgrade time) you’ve got a friend in Cyanogen. They’ve rolled out a new Release Candidate update that includes Android 2.3 and a host of performance tweaks. First thing to note is that this is an RC and if you upgrade from CyanogenMod 6 to CyanogenMod 7 RC you’ll be trading a little bit of stability and a few features that haven’t made the jump from 6 to 7 in return for the newest features of Android 2.3. If you’re not comfortable with that wait for CyanogenMod 7 to update to a final release. For the intrepid, hit up the link below to read more and grab a copy. CyanogenMod-7 Release Candidates!

• Keeping Xv Overlay configuration throughout an X session.

  - by kriss

  After upgrading my Linux system from Ubuntu 9.04 to Ubuntu 10.10, I suceeded correcting most problems (all related to Intel 82865G Integrated Graphics Adapter support and compiz is still not working but that's another matter) but for one I only have a partial solution. Whenever I play a video the colors are much too saturated. This is really a problem for tones of skins that appears reddish (everyone seems to be coming back from a ski vacation with deep sun burns). As this effect only occurs with videos, not with pictures, I finally figured out it was related to Video Overlays configuration and I can correct it typing: xvattr -a XV_SATURATION -v 120 This change the default saturation value, which is 500 and much too high in my case, at eye sight the correct value seems to be between 100 and 150. Now my problem is that I have to type the above command each time I run a video. If I type it before running the video it has no effect, if I close the video and open a new one, I have to type it again, etc. I tried to put it in Xsession and (logically) it has no effect either. How could I do to get the correct setting whenever I run a video without typing the above command every time ?

• Blank screen after GRUB (64 bit) - cannot install Ubuntu

  - by peGGi

  My laptop's specs: Lenovo IdeaPad Z570 Intel Core i5-2410M @ 2.3Ghz 6 Gb RAM DDR3 640 Gb ATAPI Hard-disk Drive @ 5,200 RPM NVIDIA GeForce G520M with Optimus switching technology Broadcom 802.11n Network Adapter REALTEK soundcard Windows 7 Home Premium 64-bit I downloaded Ubuntu Studio 11.04 and burned the iso image onto two different DVDs, using two different programs (one DVD is RW, the other is just R). I verified the hash MD5sum thing. I get as far as GRUB with the 4 options (install, advanced install, disk verification, system rescue) but no matter which one I select, I get a blank screen and nothing happens. The DVD drive spins down after about 30 seconds. Also just before the GRUB screen I get a message saying Error: "Prefix" is not set. I'm not sure if that's relevant. I have tried all the options using both DVDs. Same thing happens. I have changed the graphics setting in BIOS to UMA or Optimus, but still happens either way. I've tried booting with the wireless switch turned off, same thing happens. I downloaded 'vanilla' Ubuntu 64-bit and burned onto a CD, and the same thing happens. I have downloaded Ubuntu 32-bit and I am able to boot from the live CD (interestingly the wireless card won't work, but that's maybe another issue). I have searched extensively through these forums and other sites but I can't see anything that will help me. Is there something I'm missing? I'd really appreciate help on this. The laptop is less than 2 weeks old. I was so looking forward to getting Ubuntu Studio up and running. I've gone about as far as my technical abilities will allow.

• wine 1.4 regedit makes screen flicker on 12.04 with dual monitor setup

  - by s1lv3r

  I have a dualmonitor setup running dual 23" on 1920x1080 which has the following problem: When running any wine application (for example "wine regedit" from console) the screen flickers and the windows have artifacts like this: Also sometimes taking a screenshot using the print key will make compiz crash (starter and all window bars/menus are gone) when an wine application is started. I don't have the same problems on my notebook which has the same setup. Only difference is the notebook has ATI Graphics and this PC has nvidia. This is the output of lshw -c video: *-display Beschreibung: VGA compatible controller Produkt: G72 [GeForce 7300 LE] Hersteller: NVIDIA Corporation Physische ID: 0 Bus-Informationen: pci@0000:07:00.0 Version: a1 Breite: 64 bits Takt: 33MHz Fähigkeiten: pm msi pciexpress vga_controller bus_master cap_list rom Konfiguration: driver=nvidia latency=0 Ressourcen: irq:16 memory:fa000000-faffffff memory:d0000000-dfffffff memory:fb000000-fbffffff memory:fce00000-fce1ffff I also noticed that running xrandr from console makes the screen flicker for some seconds on this PC, which also doesn't happen on my notebook. Removing one screen from the setup will stop the flickering and the artifacts inside the wine applications from appearing. Does anybody have an advice what I could try to change to make this work?

• Ubuntu unstable, showing awkward behavior

  - by Christophe De Troyer

  Let me start off by saying that this problem can't be described in such a way that allows me to find other topics, which have some relevance to this problem. That's why I created this question. In case this question might have been asked before, I apologize. So what is the problem: My computer (Intel Core I5 2500K - with HD3000 graphics -, 6 gb DDR, 1 SSD, 3 HDD's and an Asus P8Z68 mobo) runs Windows on the SDD. But I decided to give Ubuntu a chance to be my daily OS for basic needs since it's open source and I find it a handicap of not being able to work with it. I decided to run the windows installer and install Ubuntu 12.04 to my 320 Gb hdd which was not being used in my computer. After installing it and booting it, it worked great! I spent the rest of the day/night using it, and falling for it. Great, today I booted Ubuntu (I had the choice in the bootloader as I expected). It asked me for my login and it started logging in. Now, after a few (literally) minutes of letting it "boot" I tried determining the cause of this. What I've figured out so far: When I left click on my desktop it freezes completely for a few seconds I have something like tearing in the left side menu (in games, you know) when I move my mouse around It runs well when just hovering around with my mouse, but from the point I click on something it freezes. What have I tried? I ran a HD Tune diagnostic on the HDD but the performance seems to be very close to the stock values, so I'm taking it as a good HDD. I'm trying to get to the drivers update panel for Ubuntu, but with the state it's in, it's taking a lot of time.. Could anyone point me in a direction for troubleshooting this? I'm not really a noob at all, just when using Linux.. :) Thanks in advance! Christophe,

• Gnome3 shell video corruption with ATI Radeon HD 4850 on 11.10 Oneiric

  - by AndyAtTheWebists

  I have a problem similar to what's been mentioned in a few other questions, namely: Ati incompatible with Gnome-shell? Gnome Shell Glitched Top Bar Ubuntu 11.10 I have read a number of other posts here and on other forums and have tried a bunch of different solutions. The Problem The problem manifests itself only in Gnome3. I have tried KDE, Unity and KFCE and all are fine. The graphics corruption is visible only on gnome panels (see images below). Everything works fine with the free ATI drivers, but they just lack power. The problem occurs with the proprietary ones from AMD/ATI. I have installed version 11.11 and 12.1 as per the instructions on wiki.cchtml.com/index.php/Ubuntu_Oneiric_Installation_Guide. I have the same exact problem in both cases. I have tried this on clean installs of Ubuntu 11.10 Oneiric Ocelot (x64 and x86) and on Linux Mint 12 (x64) with the same results. Also, it looks like after some time of not using it, the PC just freezes. Maybe an overheat? Will look into it. Things I've Tried I have tried the following fixes: Different versions of drivers from ATI including the latest - this worked for some, not for me. Installing Oneiric specific package generated from driver, as well as the default install Removed the Unity Global menu Disabled file manager handling desktop Disabled Compiz "detect refresh rate" Sync to VBlank in Compiz on and off Please help! This is the first time in 10 years that I've finally had the chance to switch my primary desktop to Linux (stopped doing .NET dev work), and this is really getting me down.

• How do I render only part of a texture to a point sprite in OpenGL ES for Android?

  - by nbolton

  Using the libgdx framework, I've figured out how to render a texture to a point sprite. The problem is, it renders the entire texture to the point sprite, where I only want a small part of it (since it's an isometric tile image). Here's a snippet from some demo code I wrote... create() { renderer = new ImmediateModeRenderer(); tiles = Gdx.graphics.newTexture( Gdx.files.internal("data/tiles2.png"), TextureFilter.MipMap, TextureFilter.Linear, TextureWrap.ClampToEdge, TextureWrap.ClampToEdge); Gdx.gl.glClearColor(0.6f, 0.7f, 0.9f, 1); Gdx.gl.glEnable(GL10.GL_TEXTURE_2D); Gdx.gl.glEnable(GL11.GL_POINT_SPRITE_OES); Gdx.gl11.glTexEnvi( GL11.GL_POINT_SPRITE_OES, GL11.GL_COORD_REPLACE_OES, GL11.GL_TRUE); Gdx.gl10.glPointSize(s); tiles.bind(); } render() { Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); renderer.begin(GL10.GL_POINTS); // render 3 point sprites at various 3d points renderer.vertex(-.1f, 0, -.1f); renderer.vertex(0, 0, 0); renderer.vertex(.1f, 0, .1f); // ... more vertices here if needed (one for each sprite) ... renderer.end(); }

• Oracle Database 12c and Oracle Solaris 11 DTrace

  - by Larry Wake

  As you may have heard, Oracle Database 12c is now available for Oracle Solaris and Oracle Linux. Among other things, that means we now have the opportunity to share some of the cool things the Oracle Database and Oracle Solaris engineering teams have been doing together. And here's a good one: In this screencast, Jon Haslam describes how on Oracle Solaris 11, DTrace is now integrated into Oracle Database V$ views to provide a top-to-bottom picture of a database transaction I/O -- from storage devices, through the Oracle Solaris kernel, up to Oracle Database 12c itself: With this end-to-end view, you can easily identify I/O outliers -- transactions that are taking an unusually long time to complete -- and use this comprehensive data to identify and mitigate storage system problems that were previously extremely hard to debug. This is a great example of the power of DTrace, which is just about to celebrate its 10th anniversary in the wild. The screencast has some nice examples of DTrace's power on its own, as well as diving into the DTrace/Oracle Database 12c synergy. There's more, of course.  Over on the OTN Garage blog, Rick Ramsey has put together a nice compendium of ways the OS makes the database scream, and Ginny Henningsen's written an article on the same topic.  And, we've also got an OTN page that digs further into Oracle Database / Oracle Solaris synergies.

• Why would 70-persistent-net.rules have no effect?

  - by Wes Felter

  I've got a saucy server with a lot of NICs and they end up with weird names like "rename19". I know interface names can be changed by modifying the /etc/udev/rules.d/70-persistent-net.rules file. The first clue that something is wrong is that that file did not exist even though it's supposed to be created automatically. So I decided to write my own based on advice from Linux From Scratch: ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:06:00.0", NAME="eth0" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:06:00.1", NAME="eth1" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:06:00.2", NAME="eth2" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:06:00.3", NAME="eth3" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:0c:00.0", NAME="mezz0" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:0c:00.1", NAME="mezz1" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:1b:00.0", NAME="slot1a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:1b:00.1", NAME="slot1b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:20:00.0", NAME="slot2a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:20:00.1", NAME="slot2b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:11:00.0", NAME="slot3a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:11:00.1", NAME="slot3b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:8b:00.0", NAME="slot4a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:8b:00.1", NAME="slot4b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:90:00.0", NAME="slot5a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:90:00.1", NAME="slot5b" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:95:00.0", NAME="slot6a" ACTION=="add", SUBSYSTEM=="net", BUS=="pci", KERNELS=="0000:95:00.1", NAME="slot6b" (I'm matching on PCI IDs instead of MAC addresses because I have multiple identical machines that I want to apply this configuration to.) After rebooting, nothing has changed. It's like these rules aren't even being read. There's not much going on in dmesg either: $ dmesg | grep udev [ 3.196629] systemd-udevd[323]: starting version 204 [ 6.719140] systemd-udevd[550]: starting version 204 [ 38.695050] init: udev-fallback-graphics main process (1658) terminated with status 1

• Social Retailing

  - by David Dorf

  For retailers the move to mobile has been obvious.  More and more consumers are interacting with retailers, both online and in the store, using their mobile devices.  Retailers are quick to invest in both consumer facing mobile apps as well as ones to equip employees.  But when I talk to retailers about social, the value isn't as clear-cut.  Intuitively, retailers know that better relationships with customers will result in higher sales, but the trip to get there has many paths. The interesting thing about social media is that it has the potential to permeate all parts of the business.  Obviously it works well for marketing, but it also has a place with recruiting, knowledge management, trend analysis, and employee collaboration.  Information gathered from social media can enhance existing processes like assortment planning, product development, space planning, promotion planning, and replenishment.  Letting the customer influence each of these areas helps align the experience. One of the things holding retailers back is the lack of consistent and integrated tools to manage social media and make sense of the huge amounts of data.  To that end Oracle has been aggressively acquiring in the space, as depicted in the infographic below.  Soon, social will get the same level of investment as mobile.

• Functional testing in the verification

  - by user970696

  Yesterday my question How come verification does not include actual testing? created a lot of controversy, yet did not reveal the answer for related and very important question: does black box functional testing done by testers belong to verification or validation? ISO 12207:12208 here mentiones testing explicitly only as a validation activity, however, it speaks about validation of requirements of the intended use. For me its more high level, like UAT test cases written by business users ISO mentioned above does not mention any specific verification (7.2.4.3.2)except for Requirement verification, Design verification, Document and Code & Integration verification. The last two can be probably thought as unit and integrated testing. But where is then the regular testing done by testers at the end of the phase? The book I mentioned in the original question mentiones that verification is done by static techniques, yet on the V model graph it describes System testing against high level description as a verification, mentioning it includes all kinds of testing like functional, load etc. In the IEEE standard for V&V, you can read this: Even though the tests and evaluations are not part of the V&V processes, the techniques described in this standard may be useful in performing them. So that is different than in ISO, where validation mentiones testing as the activity. Not to mention a lot of contradicting information on the net. I would really appreciate a reference to e.g. a standard in the answer or explanation of what I missed in the ISO. For me, I am unable to tell where the testers work belong.
