• Windows 8: Clean Install Fails BEFORE country Screen

  - by Mark

  G'day, I've been trying to (clean) install Windows 8 on my PC now for over two weeks now, and it's really getting old. You can see here that I've outlined my issue to the Windows Technical Community, which has resulted in... absolutely no help at all. http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_install/windows-8-clean-install-fails-before-country/64229d0a-0220-45a9-bdc6-c41062df8a75 Tl;dr? Yeah, me too. Basically, I've shrunk the HDD, it's working (I'm on that PC on XP). I've put both the x64 and the x86 DVD's, AND an another HDD with W8 installed on it from my test machine, and they ALL Fail to load. (I get the slanty windows logo, and after about 10 seconds BOOM. Sad face error screen.) I really don't want to have to remove the video card, or the unevenly/not partnered DIMM in the 2nd Memory channel - because the case is .. stupid, and in an awkward spot, but I'm running out of ideas! PS. I tried turning on ACHI tonight. All that resulted in was XP wigging out about new drivers & explorer.exe crashing. Fun times! :(

• Matrix rotation of a rectangle to "face" a given point in 2d

  - by justin.m.chase

  Suppose you have a rectangle centered at point (0, 0) and now I want to rotate it such that it is facing the point (100, 100), how would I do this purely with matrix math? To give some more specifics I am using javascript and canvas and I may have something like this: var position = {x : 0, y: 0 }; var destination = { x : 100, y: 100 }; var transform = Matrix.identity(); this.update = function(state) { // update transform to rotate to face destination }; this.draw = function(ctx) { ctx.save(); ctx.transform(transform); // a helper that just calls setTransform() ctx.beginPath(); ctx.rect(-5, -5, 10, 10); ctx.fillStyle = 'Blue'; ctx.fill(); ctx.lineWidth = 2; ctx.stroke(); ctx.restore(); } Feel free to assume any matrix function you need is available.

• Should companies require developers to credit code they didn't write?

  - by sunpech

  In academia, it's considered cheating if a student copies code/work from someone/somewhere else without giving credit, and tries to pass it off as his/her own. Should companies make it a requirement for developers to properly credit all non-trivial code and work that they did not produce themselves? Is it useful to do so, or is it simply overkill? I understand there are various free licenses out there, but if I find stuff I like and actually use, I really feel compelled to give credit via comment in code even if it's not required by the license (or lack thereof one).

• Sun T5120: Memory issue with 8GB DIMMs, "Unsupported memory configuration"

  - by watain

  I'm trying to upgrade RAM in a Sun T5120 server, replacing 2GB (Sun P/N: 501-7953-01) with 8GB DIMMs (Sun P/N: 511-1262-01). When bringing up the host system, I get the following errors on the ILOM: -> show faulty Target | Property | Value --------------------+------------------------+--------------------------------- /SP/faultmgmt/0 | fru | /SYS/MB /SP/faultmgmt/0/ | timestamp | Dec 14 15:29:42 faults/0 | | /SP/faultmgmt/0/ | sp_detected_fault | /SYS/MB/CMP0/MCU3 Forced fail faults/0 | | (IBIST) /SP/faultmgmt/0/ | timestamp | Dec 14 15:29:28 faults/1 | | /SP/faultmgmt/0/ | sp_detected_fault | /SYS/MB/CMP0/MCU2 Forced fail faults/1 | | (IBIST) /SP/faultmgmt/0/ | timestamp | Dec 14 15:29:13 faults/2 | | /SP/faultmgmt/0/ | sp_detected_fault | /SYS/MB/CMP0/MCU1 Forced fail faults/2 | | (IBIST) /SP/faultmgmt/0/ | timestamp | Dec 14 15:28:59 faults/3 | | /SP/faultmgmt/0/ | sp_detected_fault | /SYS/MB/CMP0/MCU0 Forced fail faults/3 | | (IBIST) /SP/faultmgmt/1 | fru | /SYS /SP/faultmgmt/1/ | timestamp | Dec 14 15:29:42 faults/0 | | /SP/faultmgmt/1/ | sp_detected_fault | Dec 14 15:29:42 ERROR: faults/0 | | Unsupported memory | | configuration As you can see, the only error message I get is "Unsupported memory configuration". Note that I'm absolutely sure that I placed in the DIMMs in the correct slots. Might this issue be related to the Voltage of the DIMMs? Any suggestions on how to trouble-shoot this issue? This issue seems to be similar to the one explained at "Inserted disabled" while upgrading Sun Sparc t5120 memory. However the given link http://docs.sun.com/source/820-4445-10/chapter1.html seems to point to an inexistent page...

• How does one improve one's problem-solving ability?

  - by gcc

  How can one improve one's problem-solving ability? Everyone says same thing: "a real programmer knows how to handle real problem." But they forget how they learn this ability, or where (I know in school, no one gives us any ability, of course in my opinion). If you have any idea except above ones, feel free when you give your advice solve more problems do more exercises, write code, search google then write more ... For me, my question is like "use complex/known library instead of using your own." In other words, I want your personal experience, book recommendation, webpage on problem solving. Moreover, look your problem-solving method and give us your personal ability as if it is an algorithm

• Why did Alan Kay say, "The Internet was so well done, but the web was by amateurs"?

  - by kalaracey

  OK, so I paraphrased. The full quote: The Internet was done so well that most people think of it as a natural resource like the Pacific Ocean, rather than something that was man-made. When was the last time a technology with a scale like that was so error-free? The Web, in comparison, is a joke. The Web was done by amateurs. -- Alan Kay. I am trying to understand the history of the Internet and the web, and this statement is hard to understand. I have read elsewhere that the Internet is now used for very different things than it was designed for, and so perhaps that factors in. What makes the Internet so well done, and what makes the web so amateurish? (Of course, Alan Kay is fallible, and no one here is Alan Kay, so we can't know precisely why he said that, but what are some possible explanations?) *See also the original interview*.

• 11.04 radeon screen tearing oddity

  - by Kevin Qiu

  I have a mobility radeon 5850 running 11.04 and am running catalyst 11.10 drivers. I noticed that whenever I have two windows open, one of top of the other, scrolling results in minor screen tearing, usually around the border of the window on the bottom. When I minimize or close the bottom the tearing goes away. I have tear free desktop enabled and tried looking for this specific issue but couldn't find anyone else with it. It happens in both Unity and Classic. Is there any fix for this?

• What is the most accurate/frequent report on browser usage on the Internet?

  - by Ryan Hayes

  I'm determining which browsers a new site should support. I'm looking for a respected and accurate (as possible) report on the browser versions that are currently in use. This report should, at minimum cover the % of people who use what browsers, and versions of that browser. Is there a widely accepted source for this kind of report? If so, are they regularly released and available for free? Bonus points for other metrics such as breaking down by OS, Flash versions, JS versions, etc.

• How to Multitask in the Linux Terminal: 3 Ways to Use Multiple Shells at Once

  - by Chris Hoffman

  The Linux terminal has rich multitasking capabilities. You can switch between the virtual consoles already running on your system, use Bash job control to run processes in the background, and take advantage of GNU screen, a terminal “window manager.” You don’t have to stick to a single command at a time. Whether you want to run a process in the background and revisit it occasionally or run multiple time-consuming tasks at once, Linux offers several options.

• News Portal CMS

  - by George Grigorita

  I am looking for a specific news portal CMS. I know all the major "general" CMS (like WordPress, Drupal or Joomla) and even the less known ones (like TYPO3, Expression Engine, Text Pattern or Concrete5). I'm already working with a Drupal distribution called OpenPublish and another WordPress installation to determine which would be better, but these are more of a Plan B. I would like to work directly with a CMS that was build exactly for this kind of tasks specific to a news / media portal. It doesn't matter if the CMS is commercial (however, I don't want to pay a monthly fee) or free, but I need to be able to use it on my own server / hosting and I need to be able to access it's source code (not to modify it, but to integrate it with future plugins / modules). If you know any CMS that qualifies for this job, please let me know. In the last few days I was all over Google but I couldn't anything worth mentioning.

• Bad sectors, S.M.A.R.T., SpinRite, firmware on platter and drive id questions.

  - by Christopher Galpin

  Is it possible for S.M.A.R.T. to give false readings (say I was fiddling with lots of recovery programs, transfers, so on and so forth) or is it absolutely a read-only direct correlation to the physical status of a drive? Does SpinRite level 5 "recover bad sectors" operate on those marked at the factory? Are they on the same level as your generic bad sector, with SpinRite thus having full access? (Also I'm curious if SMART's bad sector count is zero'd afterward or if it includes factory marked sectors.) The main firmware of some drives, like a WD Passport is stored on the platter. How is it protected? Is it through marking them as bad sectors? If so, I'm wondering if SpinRite's sector recovery could bring about firmware corruption on these drives. Is the failure of a drive to report valid identity information (hdparm -I /dev/xx) consistent with corrupted firmware, or just general disk failure? I may be misunderstanding the role of firmware here. I feel I've read a drive's identity information is on the platter, just like the partition tables and so on. Is this true? (Apologizes if this is more appropriate for SuperUser.)

• IPSec for LAN traffic: Basic considerations?

  - by chris_l

  This is a follow-up to my Encrypting absolutely everything... question. Important: This is not about the more usual IPSec setup, where you want to encrypt traffic between two LANs. My basic goal is to encrypt all traffic within a small company's LAN. One solution could be IPSec. I have just started to learn about IPSec, and before I decide on using it and dive in more deeply, I'd like to get an overview of how this could look like. Is there good cross-platform support? It must work on Linux, MacOS X and Windows clients, Linux servers, and it shouldn't require expensive network hardware. Can I enable IPSec for an entire machine (so there can be no other traffic incoming/outgoing), or for a network interface, or is it determined by firewall settings for individual ports/...? Can I easily ban non-IPSec IP packets? And also "Mallory's evil" IPSec traffic that is signed by some key, but not ours? My ideal conception is to make it impossible to have any such IP traffic on the LAN. For LAN-internal traffic: I would choose "ESP with authentication (no AH)", AES-256, in "Transport mode". Is this a reasonable decision? For LAN-Internet traffic: How would it work with the internet gateway? Would I use "Tunnel mode" to create an IPSec tunnel from each machine to the gateway? Or could I also use "Transport mode" to the gateway? The reason I ask is, that the gateway would have to be able to decrypt packages coming from the LAN, so it will need the keys to do that. Is that possible, if the destination address isn't the gateway's address? Or would I have to use a proxy in this case? Is there anything else I should consider? I really just need a quick overview of these things, not very detailed instructions.

• How to Follow a Twitter Feed in Your RSS Reader

  - by Lori Kaufman

  You probably have an RSS reader you really like and several feeds you follow. We encountered a situation recently where we had a Twitter feed for free eBooks (HundredZeros), but no RSS feed on the website and no RSS button on the Twitter feed. NOTE: See our recent article about HundredZeros for more information about it. We wanted to add the Twitter feed for HundredZeros (https://twitter.com/#!/HundredZeros) to our RSS reader so all our feeds are available in a centralized place. However, you can’t simply paste the URL for the Twitter feed into your RSS reader. You must determine the ID for the Twitter name first. There is a site, called TwIDder, that allows you to convert from a Twitter username to the corresponding ID and from an ID to a Twitter username.

• Release an upgraded iOS app with a different revenue model

  - by tassock

  I am starting a new iOS project and initially plan release a simple free version to gather feedback. I don't intend to monetize or market this initial version. However, I believe "Version 2" of this app will be good enough to pay for. I would prefer to release Version 2 as an upgrade from Version 1 rather than release it as a separate app. This way I can reserve a name for the app. It will also be easier to keep everything in a single repository. Are there any downsides of this approach? It's my understanding that I can change the price of an app at any point in time, so it shouldn't be an issue transitioning to a paid app, should it?

• Easy user management on html site?

  - by James Buldon

  I hope I'm not asking a question for which the answer is obvious...If I am, apologies. Within my html site (i.e. not Wordpress, Joomla, etc.) I want to be able to have a level of user management. That means that some pages I want to be only accessible to certain people with the correct username and password. What's the best way to do this? Are there any available scripts out there? I guess I'm looking for a free/open source version of something like this: http://www.webassist.com/php-scripts-and-solutions/user-registration/

• Command line method to find disk usage of camera mounted using gvfs

  - by Hamish Downer

  When my camera was mounted on /media I could use the standard tools (df) to see the disk usage of the card in my camera. However now the camera is mounted using gvfs, and df seems to ignore it. I've also tried pydf and discus to no avail. The camera is definitely available through nautilus, and when I select the camera in nautlius, the status bar tells me the amount of disk free. I can also open the ~/.gvfs/ folder in nautilus and right click on the camera folder and get the disk usage in a graphical way. But that is no use for a script. Are there command line tools that are the equivalent of df for gvfs filesystems? Or even better, a way to make df report on gvfs filesystems?

• How to play Minecraft Classic?

  - by djeikyb

  First off, I've read through this question: How to install minecraft?. I'm interested in the free web-embedded version (for demo purposes), not the paid and downloaded .jar file. I removed the open-java whatever that Ubuntu prefers to use. I installed sun-java6-jre. Then I ran sudo update-alternatives --config java to ensure I was using Sun's Java. Restarted my browsers, then tried to start the game from: http://www.minecraft.net/play.jsp It pops a prompt to make sure I really want to allow direct interaction between minecraft.net and my computer, I agree. The in browser display mumbles something about loading a library, then darkness. The page doesn't crash, ps shows the java plugin process, all seems well except the game doesn't load. I see the same behaviour on Chromium 11.0.662.0 (73963) as Firefox 4 RC1.
