• Problem graphics with ATI Radeon x1270 (RS690M) on Ubuntu 12.04

  - by Giuseppe Della Corte

  I'm Italian and so I apologize for my English! I'm a beginner to Ubuntu and I tried it on my desktop PC and it's fantastic, fast and fun! I decided to try it on my netbook Packard Bell DOT M/A and this is the configuration: AMD Athlon L110 1.2GHz 2GB of RAM ATI Radeon x1270 (RS690M) 150GB Hard Disk I installed Ubuntu 12.04 with Wubi (dualboot Windows 7 + Ubuntu 12.04), because the netbook does not have a DVD player! During the installation everything is OK, after it was installed I see mistakes in the graphical display! I see objects that are seen in different colors and moving (buttons, mouse pointer, text bar ... etc ...) At one point came not to see anything, such as this screenshot: The drivers are open, that is already installed in Ubuntu. Windows 7 video card runs fine, can run well Aero (transparent window effects), I can watch movies in HD and play some games with the Catalyst drivers from AMD. Now I ask a favor, you can help me solve this problem? Is there a fix for this driver or drivers different on the Internet? Thanks for your attention, good bye!

• Screen doesn't turn back on after resume on a Lenovo Thinkpad T420

  - by Wojtek

  Every time I suspend my notebook (Lenovo Thinkpad T420 - Intel HD graphic card) on Oneiric Ocelot 11.10 and turn it back on, the screen is black. The backlight is on and the system itself loads fine, but the display somehow doesn't get back. The first time after a fresh reboot the screen isn't black, it is mostly white/light-gray and it looks a bit like a distorted image. The pixels fade in until it gets almost completely light-gray. I've got a workaround for this: I switch to the first terminal (CTRL+ALT+F1) and back to X (CTRL+ALT+F7). In most cases that helps. Sometimes, when there's still a problem, I log in on the first terminal and run "unity --reset". Then go back to X - this helps always. I can tell that the system comes back, because I can log in with my fingerprint reader (or wait a bit and put in the password) "blindly", then do the workaround - I am logged in after the screen comes back. So it's only the display that is not working. Any help or advice where to look would be appreciated.

• External monitor problems with Asus UX32VD in 12.04

  - by rsilva

  I've posted this video where I show one of the problems I'm facing with my UX32VD in regard of external monitors. As you can see as soon as I plugged the external monitor the laptop screen goes black and the external monitor displays a single color (color changes between red, green and blue). However this does not always happen. For instance if I reboot the laptop with the external monitor already plugged in I get to use it but not the laptop screen. In the Displays settings the laptop screen it's not even listed. Other times it just works. The to screens, without any problems. I tried with other to different external monitor and all this apparently random issues repeat, I even tried using HDMI cable instead. Same random behavior. This question seams to cover one of this issues however the answer did not helped me. I was forced to use the 3.5.2 kernel in order to use the Intel graphics card else the Gallium something was used. Also I've Bumblebee installed.

• How to store bitmaps in memory?

  - by Geotarget

  I'm working with general purpose image rendering, and high-performance image processing, and so I need to know how to store bitmaps in-memory. (24bpp/32bpp, compressed/raw, etc) I'm not working with 3D graphics or DirectX / OpenGL rendering and so I don't need to use graphics card compatible bitmap formats. My questions: What is the "usual" or "normal" way to store bitmaps in memory? (in C++ engines/projects?) How to store bitmaps for high-performance algorithms, such that read/write times are the fastest? (fixed array? with/without padding? 24-bpp or 32-bpp?) How to store bitmaps for applications handling a lot of bitmap data, to minimize memory usage? (JPEG? or a faster [de]compression algorithm?) Some possible methods: Use a fixed packed 24-bpp or 32-bpp int[] array and simply access pixels using pointer access, all pixels are allocated in one continuous memory chunk (could be 1-10 MB) Use a form of "sparse" data storage so each line of the bitmap is allocated separately, reusing more memory and requiring smaller contiguous memory segments Store bitmaps in its compressed form (PNG, JPG, GIF, etc) and unpack only when its needed, reducing the amount of memory used. Delete the unpacked data if its not used for 10 secs.

• Hard time installing Ubuntu

  - by Nick

  I have a MSI GT780DXR that currently is booting windows 7. I've been trying to dual boot windows 7 and ubuntu for some time now. Here's specs that I think would make a difference Windows 7 500GB*2 RAID 0 hard drives. (Hardware RAID I'm not sure if it's a dedicated RAID card though) 7200RPM Nvidia GT570M Background: I tried to install 12.04 (64 bit) a few times but the Desktop live cd and pendrive boots with a black screen. I've tried wubi but it boots to a black screen as well. I then tried the alternative 12.04 (64 bit) and went through the installation all the way til partitioning. I let Ubuntu notice the raid setup and I setup my swap, /, and home drives, I used my free space to create the three partitions. I tried to resize the windows drive and it told me I couldn't and to be happy with my current setup. When I finally got past I got an error on installing GRUB 2 and decided to skip it and continued on to finish installation. When I tried to boot up I got an invalid partition table error. Windows recovery disc, and a GPARTED live cd couldn't find any hard drives. I ended up following advice and typed this into the recovery command prompt. bootrec /fixmbr bootrec /fixboot bootrec /rebuildBcd It worked and here I am now. The question is, how would I be able to dual boot windows 7 and Ubuntu 12.04 with this information? Thanks,

• Ubuntu 12.04 slow boot on ASUS, attached with dmesg and bootchart

• The MsC gray zone: How to deal with the "too unexperienced on engineering/too under-qualified for research" situation?

  - by Hunter2

  Last year I've got a MsC degree on CS. On the beginning of the MsC course, I was keen on moving on with research and go for a PhD. However, as the months passed, I started to feel the urge to write software that people would, well, actually use. The programming bug had bitten me, again. So, I decided that before deciding on getting a PhD degree, I would spend some time on the "real world", working as a software developer. Sadly, most companies here in Brazil are "services" companies that seem to be stuck on the 80s when it comes to software development. I have to fend off pushy managers, less-than-competent coworkers and outrageous software requirements (why does everyone seem to need a 50k Oracle license and a behemoth Websphere AS for their CRUD applications?) on a daily basis, and even though I still love software development, the situation is starting to touch a nerve. And, mind you, I'm already lucky for getting a job at a place that isn't a plain software sweatshop. Sure, there are better places around here or I could always try my luck abroad, but then I hit the proverbial brick wall: Sorry, you're too unexperienced as a developer and too under-qualified as a researcher I've already heard this, and variations of that, multiple times. Research position recruiters look for die-hard, publication-ridden, rockstar PhDs, while development position recruiters look for die-hard, experience-ridden, rockstar programmers. To most, my MsC degree seems like a minor bump on my CV (and an outright waste of time for some). Applying for abroad positions is even harder, since the employer would have to deal of the hassle of a VISA process, which I understand that, sometimes, is too much. Now I'm feeling I've reached a dead-end. I'm certain that development (and not research) is my thing, so should I just dismiss my MsC (or play it as a "trump card") and play the "big fish on a small pond" role while I gather some experience and contribute on some open-source projects as a plus? Is there a better way to handle this?

• Does your organization still use the term "screens" to describe a user interface?

  - by bit-twiddler

  I have been in the field long enough to remember when the term "screen" entered our lexicon. As difficult as it is to believe, the early systems on which I worked had no user interface (UI), that is, unless one counts a keypunch machine and job listings as a user interface. These systems ran as "card image" production jobs back in a day when being a computer operator required a reasonably deep understanding of how computers worked. Flashing forward to today: I cringe every time I hear a systems practitioner use the term "screen." The metaphor no longer fits the medium. The term somewhat fit back when the user dialog consumed 100% of available monitor real estate; however, the term lost its relevance the moment we moved to windowed environments. With the above said, does your organization still use the term "screens" to describe an application's UI? Has anyone successfully purged the term from an organization? For those who do not use the term to describe UI dialog elements, what term do you use in place of “screen.”

• The Mac Tax

  - by Robert May

  One of our users was having difficulties with their mac and using some web software.  I decided to go peruse the landscape and see how much of a premium people were paying for their macs.  I priced out a Dell and a Mac from their websites.  I tried to get them as close to the same configuration, from a hardware standpoint, as I could.  I found the following: Apple Macbook Pro   Dell XPS 17 There are several important differences in the hardware: The mac doesn’t have a blueray player, but the dell does. The mac has a slightly slower processor. The mac claims to have a better battery, but doesn’t list the specifics, so there’s no way to tell. The mac doesn’t list the video card stats, so there’s no way to tell how comparable they are, but they’re probably close. The mac doesn’t come with any additional software.  No iWorks, iPhoto, etc.  They were left to their default of None, so arguably, the Dell is more functional out of the box. Other than changing the hardware specs to be close, all other configuration options were left at their default. So riddle me this, Batman:  Why do people buy Macs?  I have several dev buddies that own them, but I can’t justify the cost.  First, most of them load bootcamp and/or parallels at extra cost to run windows 7 and windows apps.  The hardware isn’t as good.  The price is almost twice as expensive. How do you justify the premium price? Technorati Tags: General

• Raspberry Pi, Time Capsule Progress

  - by Richard Jones

  So by way of an update. I thought all was good with my Raspberry Pi, Debian and Netatalk Apple Time Capsule Clone. However something very strange going on. Although I could backup my Mac's + PC's fine to Raspberry Pi with external USB HD; strangely with RPI running, I couldn't use AirPlay. I found myself unable to play anything from Mac to Apple TV. So after lots of trying to make this work, I about turned and finally went out and got myself a 2TB Apple Time Capsule. More cash than I would want to spend on anything like this, but Apple you got me. I would like to offer a top tip, which maybe goes a small way to justifying silly expenditure... You can easily add a USB HD to any Time Capsule. I've just added a 3 TB external USB HD, giving me a 5 TB of total backup grunt. 3 TB External USB HD, was peanuts by comparison to Apple kit. So all working, its all solid as you'd expect.Apple 2, maybe me .5. But strong, solid backups now happening, without hassle (but a bit of a credit card bill to follow)

• Newbie tips, please [closed]

  - by eXeP

  So, I just got a new computer and I want to put Ubuntu on my old laptop. I just need few tips before installing it. 1.Programs, where to download, how to download, what is the "ending" (windows has .exe) 2. How much is command line involved? And where to get the most usual commands? 3.Few programs you recommend (graphics editing, IDE, video player, web browser) 4. Do I have to download drivers when installing new OS? I plan on getting fully rid of Windows. I have no idea of the name of my graphics card, so how do I can get to know what it is if I have to download drivers? (I don't know the name because it's not on the original box, or anywhere on the internet, believe me) 5. When installing new OS does it destroy everything else on the hard drive? 6. Anti-virus, do I need one? I'm not super paranoid, and I don't visit "shady" sites. Please note that I have never used linux, or any other OS than Windows and sorry for my bad english. If this is the wrong place to post this, then please remove this. Thank you.

• Switching DVI socket

  - by lurscher

  I have Ubuntu 10.10 x86_64 with Nvidia 9800 gt and Nvidia driver version 270.41.06 My video card has two DVI sockets, but I only use the single monitor configuration. Now, I think the main DVI socket might be busted, so I want to try to enable the other as the main one, however, I don't know how to achieve that. I tried just plugging the monitor in that socket but it won't auto-detect it (it would have been way too easy to just work).

• Why does Unity not extend to my 2nd monitor, even when it is displaying an X-Screen?

  - by Gridwalker

  I recently added a 2nd video card to my system, but unity refuses to extend my desktop over to the second screen. Although the secondary monitor initialises when I boot and I can move the mouse cursor over to the 2nd screen, the screen is otherwise blank (showing no wallpaper or interface elements) and I am unable to move any windows to this monitor. Moving the mouse cursor over to the 2nd monitor changes it from the default cursor to the old-style X cursor, such as the one that appears when you run X-kill, indicating that this screen is initialised in the X Server but that Unity is not recognising it. Although the Nvidia X Server Settings application can see both monitors, the unity systems settings application does not detect the 2nd adapter. Sometimes the additional drivers application can see both adapters, but it doesn't consistently show options for them both. Xrandr also fails to detect the 2nd monitor, but iNex lists both adapters. I have experimented with several different drivers for each adapter and with setting each of the graphics cards as the primary adapter in the BIOS, but this has made little difference. The two adapters are an onboard Geforce 8200 and a PCIE Geforce 7200 GX. The onboard adapter is currently set as the primary, however this adapter crashes whenever I use the Nouveau driver and I have to switch over to the PCIE as a primary whenever I purge the proprietary drivers (switching back when the 304 driver has been reinstalled). It doesn't matter which adapter I set as my primary, the results are the same : one screen showing the unity interface and one screen showing an X-Screen that only displays the mouse cursor. All I want is to be able to run this system in a dual screen configuration. I am not a gamer, nor do I require 3D rendering capabilities. Anything you can suggest to get the desktop to extend across both screens will be massively appreciated!

• Visually and audibly unambiguous subset of the Latin alphabet?

  - by elliot42

  Imagine you give someone a card with the code "5SBDO0" on it. In some fonts, the letter "S" is difficult to visually distinguish from the number five, (as with number zero and letter "O"). Reading the code out loud, it might be difficult to distinguish "B" from "D", necessitating saying "B as in boy," "D as in dog," or using a "phonetic alphabet" instead. What's the biggest subset of letters and numbers that will, in most cases, both look unambiguous visually and sound unambiguous when read aloud? Background: We want to generate a short string that can encode as many values as possible while still being easy to communicate. Imagine you have a 6-character string, "123456". In base 10 this can encode 10^6 values. In hex "1B23DF" you can encode 16^6 values in the same number of characters, but this can sound ambiguous when read aloud. ("B" vs. "D") Likewise for any string of N characters, you get (size of alphabet)^N values. The string is limited to a length of about six characters, due to wanting to fit easily within the capacity of human working memory capacity. Thus to find the max number of values we can encode, we need to find that largest unambiguous set of letters/numbers. There's no reason we can't consider the letters G-Z, and some common punctuation, but I don't want to have to go manually pairwise compare "does G sound like A?", "does G sound like B?", "does G sound like C" myself. As we know this would be O(n^2) linguistic work to do =)...

• Thinkpad W510 with default graphics drivers shows weird brightness issues

  - by Chantz

  Hey guys, I am currently running 10.10 - 32 bit on a new Thinkpad W510 with nVidia Quadro FX 880M graphics card. I am running with the default graphics drivers that installed with ubuntu install. My problem is that when I am logging in the screen acts normally as far as birghtness is concerned. I can increase/decrease brightness with Fn keys. But few seconds after I log in screen goes pitch dark. Hitting Fn+Home flickers the screen to all the way bright, then all the way dark. This behavior continues until I reach maximum brightness, in which case the screen stays all the way bright, for a few more seconds and then again goes dark if there is no activity & the cycle continues. Have you guys faced any of these issues? If so any pointers on how to resolve it. I am not alone, on ubuntu forum I saw another person having the same issue - link but no solution. Please help! UPDATE I followed the instructions that htorque mentions in his answer and it worked.

• Greeter login screen cropped login options in 12.04

  - by ammianus

  I have a pretty newly installed Ubuntu 12.04, using Unity. My external monitor is 1920x1080 max resolution. In the Unity desktop itself everything looks great. I have an NVidia graphics card. When I start my computer and get to the Unity greeter login screen the display is oddly formatted and the resolution seems off. It looks like a zoomed view on the larger 1920x1080 screen. As such it crops the login options off to the left hand side of the screen. So I can only just see the edge of the password box for the user I want to log in with. I can log in with one account by default by blindly typing the password, but I am unable to switch to other accounts. Is there anything I can do to fix the log in screen display so that I can see the normal login options? Note: I first noticed it when I changed my desktop background and the next time I logged in I saw the issue.

• Trying to install Proprietory Nvidia Graphics Drivers

  - by Peter Snow

  After reading and trying many different suggestions for some hours, I returned to this how-to: https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia The first problem I encounter is how to identify which of the listed drivers support my Nvidia GEForce 630M graphics card. Following the links doesn't really help, since it is not stated there either (except where support for a new driver was added later which is explicitly stated, but the original devices covered are not). However, even if I knew, if it doesn't appear in the 'Additional Drivers' dialogue (see below), how will I install it? Second Issue: The article goes on to say that available drivers for my hardware are usually listed in 'Additional Drivers'. In my case, they aren't. Unfortunately, it doesn't tell me how to correct that or work around it? I've checked the bios and there is no way offered there to disable the integrated graphics, only the Nvidia graphics. I've also tried each available option in this: $ sudo update-alternatives --config i386-linux-gnu_gl_conf My system is an Acer Aspire 4752G bought May 2012. I'm running Ubuntu 12.04LTS. uname -a : 3.2.0-38-generic-pae #61-Ubuntu SMP Tue Feb 19 12:39:51 UTC 2013 i686 i686 i386 GNU/Linux It's 64bit hardware but I installed 32bit OS for greater software compatibility. Running $ sudo tail -fn 500 /var/log/Xorg.0.log | grep '(EE)' returns" (WW) warning, (EE) error, (NI) not implemented, (??) unknown. [ 28.886] (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found) The reason for wanting the proprietor y drivers is because my laptop comes with 3D accelerated graphics adaptor and so rather than confining myself to struggling with the on-board graphics, I would rather use it. I also want to experiment with using it for bitmining (which uses the GPU's for computing power).

• Installing ubuntu 12.04 on macbook pro9,2

  - by stariz77

  I seem to have tried all the various suggested methods for installing ubuntu on a mbp, but can't seem to get anything that works and was wondering if anyone has run into any new problems with the latest non-retina models? I have a core i7 in my macbook, and model identifier is MacBookPro9,2. I have partitioned my HD using disk utility and have 700gig free space ready for the install (I haven't removed OSX Lion, it is still there in a 50gig partition). Problem: I am just getting a blank screen with a blinking cursor (unresponsive) in the top left whenever I boot from the disk. I left it for 20 minutes and nothing ever happened. This was without any boot manager, just holding "c" on startup. Attempted remedies: I have downloaded the 64 ubuntu iso from their site 3 times now and burned 4 separate discs to rule out some kind of corruption or burn error. I burned one in OSX Lion 10.7.4 and 3 on my windows 7 pc. I tried holding "alt" instead and then navigating to the windows disc to boot. Same thing happens, blank blinking unresponsive cursor. I also tried going to the EFI disc which actually brings up a menu (after saying "error prefix is not set") asking if I want to install ubuntu, test for errors or partition. All three options lead me to an unresponsive blank screen (some without cursors). I downloaded and installed rEFIt and if I hold "alt" on startup a linux penguin (Boot Linux from CD) appears in my boot options, along with the apple boot, and two others that I'm not sure of: "Boot EFI\boto\bootx64.efi from" and "Boot Legacy OS from". The "Boot Linux from CD" just takes me to the blank blinking cursor screen; again, I left if for 10+ minutes and nothing. I heard that the detection of the graphics card might be a problem and that I need change to nomodeset, but I have tried pressing F6 in all of the boot menus listed above and no options appear. Does anyone have any other suggested routes or can you see what I might have done wrong?

• Pandaboard crash on startup or freeze after minutes

  - by Meach

  I just received my Pandaboard ES (rev B) and I am having trouble after installing ubuntu-omap4-addons. Once I copied the image ubuntu-12.04-preinstalled-desktop-armhf+omap4.img on my sd card and boot the pandaboard with it, I run the following commands: sudo add-apt-repository ppa:tiomap-dev/release sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install ubuntu-omap4-extras At the end of the installation of ubuntu-omap4-extras, Ubuntu tells me that a problem occurs when the console displays: ldconfig deferred processing now taking place Clicking on "report the problem" tell me that the problem concerns pvr-omap4-dkms. I read somewhere that this can happen and it is better to reinstall pvr-omap4-dkms. Which I am doing by running: sudo apt-get install --reinstall pvr-omap4-dkms I reboot. Then the board has sometimes difficulties to start Ubuntu: it freezes during the loading page, only action I can do is unplugging the board to start it again. Some other times, Ubuntu load successfully but then freeze at another random time, in the range 20 - 40 minutes. I searched on internet for similar bug and found this: https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/971091 So I typed this in: update-rc.d ondemand disable apt-get -y install cpufrequtils echo 'ENABLE="true" GOVERNOR="performance" MAX_SPEED="0" MIN_SPEED="0"' > /etc/default/cpufrequtils cpufreq-set -r -g performance reboot But it doesn't seems to fix the bug. Another detail: on startup, before the loading screen of Ubuntu (when there is the two penguins displayed :)), it shows this: [0.297271] CPU1: Unknown IPI message 0x1 [0.308990] omap_hwmod: mcpdm: _wait_target_ready error: -16 [0.354705] omap_mux_get_by_name: Could not find signal uart1_cts.uart1_cts [0.354766] omap_hwmod_mux_init: Could not allocate device mux entry [2.107086] thermal_get_slope:Getting slope is not supported for domain gpu [2.107116] thermal_get_offset:Getting offset is not supported for domain gpu [2.107299] stm_fw: vendor driver stm_ti1.0 registered [8.725555] OMAPRPC: Registration of OMAPRPC rpmsg service returned 0! debug=0 Any idea what can be wrong? I am not that good with Ubuntu so any help will be appreciated. Cheers! Meach

• How to write code that communicates with an accelerator in the real address space (real mode)?

  - by ysap

  This is a preliminary question for the issue, where I was asked to program a host-accelerator program on an embedded system we are building. The system is comprised of (among the standard peripherals) an ARM core and an accelerator processor. Both processors access the system bus via their bus interfaces, and share the same 32-bit global physical memory space. Both share access to the system's DRAM through the system bus. (The computer concept is similar to Beagleboard/raspberry Pie, but with a specialized accelerator added) The accelerator has its own internal memory (SRAM) which is exposed to the system and occupies a portion of the global address space (as opposed to how a graphics card would talk to teh CPU via a "small" aperture in the system memory space). On the ARM core (the host) we plan on running Ubuntu 12.04. The mode of operation of communicating between the processors should be that the host issues memory transactions on the system bus that are targeted at the accelerator internal memory. As far as my understanding goes, if I write a program for the host that simply writes to the physical address of the accelerator, most chances are that the program will crash due to a segmentation violation. So, I assume that I need some way of communicating with the device in real mode. What is the easiest way to achieve this mode of operation?

• IIM Calcutta &ndash; EPBM14 &ndash; Campus Visit &ndash; Day 3 &ndash; Kali Temple, IS &amp; Strateg

  - by Ram Shankar Yadav

  Hey folks~ Today was one of the most happening day for us, we got up @ 5 AM and did our daily morning chores and left hostel room by 5:35 AM. So why we got up so early??? Okay we planned a visit to Kali Temple at KaliGhat! So till everyone assembles, we took few pics on the Lake Deck. We left Joka campus at 6 AM and reached Kali temple at 6:50 AM. Kali temple is very famous in Kolkata, but the frankly speaking it’s one of the most unorganised one for sure~! After darshan, we got back into our Taxis and headed for breakfast at Gupta Brothers Restaurant. We enjoyed “doodh-jalebi”, “Kachori-sabzi” and rasogullas there~! While coming back, one of our Taxi’s excel broken and we waited for the first to come back and take us to Campus. After coming back to campus, we attended our sessions on IS & Strategy on ITC eChaupal and Transactional Cost and Vertical Integration(TCVI). After our classed we had “Dinner Party” organised by IIMC, and we enjoyed it thoroughly, and many of us took this as an opportunity to share our biz card and talk to Professors. Overall it’s was a rocking day!! Stay tuned for more… Cheers, ram :)   Photo Album :

• Why is purchasing Microsoft licences such a daunting task? [closed]

  - by John Nevermore

  I've spent 2 frustrating days jumping through hoops and browsing through different local e-shops for VS (Visual Studio) 2010 Pro. And WHS (Windows Home Server) FPP 2011 licenses. I found jack .. - or to be more precise, the closest I found in my country was WHS OEM 2011 licenses after multiple emails sent to individuals found on Microsoft partners page. Question being, why is it so difficult to get your hands on Microsoft licenses as an individual? Sure, you can get the latest end user operating systems from most shops, but when it comes to development tools or server software you are left dry. And companies that do sell licenses most of the time don't even put up pricing or a self service environment for buying the licenses, you need to have an hawk's eye for that shiny little Microsoft partner logo and spam through bunch of emails not knowing, if you can count on them to get the license or not. Sure, i could whip out my credit card and buy the VS 2010 license on the online Microsoft Shop. Well whippideegoddamndoo, they sell that, but they don't sell WHS 11 licenses. Why does a company make it so hard to buy their products? Let's not even talk about the licensing itself being a pain.

• Hello PCI Council, are you listening?

  - by David Dorf

  Mention "PCI" to any retailer and you'll instantly see them take a deep breath and start looking for the nearest exit.  Nobody wants to be insecure, but few actually believe that PCI does anything more than focus blame directly on retailers.  I applaud PCI for making retailers more aware of the importance of security, but did you have to make them PAINFULLY aware?  POS vendors aren't immune to this pain either as we have to undergo lengthy third-party audits in addition to the internal secure programming programs.  There's got to be a better way. There's a timely article over at StorefrontBacktalk that discusses the inequity of PCI's rules, and also mentions that the PCI Council is accepting comments until April 15th. As a vendor, my biggest issue with PCI is that they require vendors to disclose the details of any breaches, in effect "ratting out" customers.  I don't think its a vendor's place to do this.  I'd rather have the trust of my customers so we can jointly solve the problem. Mary Ann Davidson, Oracle's Chief Security Officer, has an interesting blog posting on this very topic.  Its a bit of a long read, but I found it very entertaining and thought-provoking.  Here's an excerpt: ...heading up the list of “you must be joking” regulations are recent disturbing developments in the Payment Card Industry (PCI) world. I’d like to give [the] PCI kahunas the benefit of the doubt about their intentions, except that efforts by Oracle among others to make them aware of “unfortunate side effects of your requirements” – which is as tactful I can be for reasons that I believe will become obvious below - have gone, to-date, unanswered and more importantly, unchanged. I encourage you to read the entire posting, Pain Comes Instantly, and then provide feedback to the PCI Council.
