• Suse 12.3 cannot boot after a forced shutdown

  - by David Dai

  I was doing a system update using zypper update After a while the screen was filled with this message failed to start system logging service. and the system was not responding. I had to shutdown it by holding the power button. then I started the machine again, and selected to boot suse. Then I saw the fancy boot animation(some shiny big dots gathering to the center of the screen), then the screen just turned black and the monitor sayed "no signal". then I tried to boot into suse failsafe mode, which was fine. how can I investigate into this problem?

• Intel Core i7-4960HQ vs. 4850HQ (Haswell) [on hold]

  - by Timothy R. Butler

  I'm looking at the new MacBook Pros and trying to decide between the Core i7-4960HQ (2.6 GHz) and i7-4850 (2.3 GHz). I've found some synthetic benchmarks comparing them, but I haven't found a lot of data, so I'd appreciate any pointers to good comparisons for the Haswell family (especially these two processors). My cursory analysis seems to suggest there isn't a huge gain from the extra 300 MHz. I'd like to determine not only whether this is generally true, but also to figure out if the gains that are made in performance come at too high of cost. Is the 2.6 going to be pushing the limits of what can fit in a thin laptop without overheating? I've looked at some of Intel's documentation, but have not been able to determine what the normal and maximum operating temperature differences are for the models. In the past, there have been times that Intel's fastest models in a given range ran especially hot and/or consumed significantly more power compared to slightly slower models. Do those concerns factor into the current generation?

• Using Windows 7 drivers in Windows Server 2008 R2

  - by Robert Koritnik

  Maybe I should post this to http://www.serverfault.com. Windows 7 comes with all sorts of signed drivers so there's high probability that all drivers for your machine will be installed during system setup. On the other hand Windows Server 2008 doesn't event though it's practically the same OS when it comes to drivers. But I know that this has a very good reason. It's a server product, not a desktop one. But the thing is that many power users and developers use server OS on their workstations which are normally desktop machines and would need Windows 7 driver spectrum... Question I know I've been reading about some trick on the internet that first installed Windows 7 on the machine, than do something to get either all Windows 7 driver collection or just those installed, and then install Windows Server 2008 and use those drivers. The thing is: I can't seem to find these instructions on the internet any more. If anybody knows where these are please provide the link for the rest of us.

• iPhone - dequeueReusableCellWithIdentifier usage

  - by Jukurrpa

  Hi, I'm working on a iPhone app which has a pretty large UITableView with data taken from the web, so I'm trying to optimize its creation and usage. I found out that dequeueReusableCellWithIdentifier is pretty useful, but after seeing many source codes using this, I'm wondering if the usage I make of this function is the good one. Here is what people usually do: UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"Cell"]; // Add elements to the cell return cell; And here is the way I did it: NSString identifier = [NSString stringWithFormat:@"Cell @d", indexPath.row]: // The cell row UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:identifier]; if (cell != nil) return cell; cell = [[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:identifier]; // Add elements to the cell return cell; The difference is that people use the same identifier for every cell, so dequeuing one only avoids to alloc a new one. For me, the point of queuing was to give each cell a unique identifier, so when the app asks for a cell it already displayed, neither allocation nor element adding have to be done. In fine I don't know which is best, the "common" method ceils the table's memory usage to the exact number of cells it display, whislt the method I use seems to favor speed as it keeps all calculated cells, but can cause large memory consumption (unless there's an inner limit to the queue). Am I wrong to use it this way? Or is it just up to the developper, depending on his needs?

• Open Source webapp that shows PC / Projector status in 30+ Lecture rooms

  - by Seanchán

  I am looking for a simple web application that only has a simple graphical representation of the current status of 30+ lecture rooms. I.e. Green = good, Red=bad i.e. PC or Projector not working. With a little message and a ETA as well. I am not looking for monitoring software, merely a way for a tech to flag a room as "technically challenged" until 1PM or until "Friday 10AM". With a message for those lecturers who are interested: "Waiting on replacement bulb" or "Power supply gone" I know this is a simple thing to code up yourself, but I am looking for something that has been around for a few years that has some cool extra little functionality that you wouldn't think of yourself. I just can't find anything like that out there. And just to be clear: not monitoring software, more like lecturer feedback web app.

• Merit and demerits for various Linux fiberchannel multipath options

  - by wzzrd

  On our Linux servers, we currently use HPs qla2xxx drivers, because it has multipathing (active/passive) built in. The are, however, various other options, like Red Hats device-mapper-multipath with the stock qla2xxx drivers (multibus and failover) and things like SecurePath and PowerPath (both of which can do trunking, iirc). Can someone tell me what the merits and demerits of the various options are (if I can ask such a question), besides the obvious fact that the {Secure,Power}Path options cost vast amounts of money? I'm mainly interested in the freely available options, like HPs qla2xxx vs. Red Hats multipathd and possible other open source solutions, but I would like to hear good reasons to go for the commercial solutions too. UPDATE: I'll be benchmarking various options the coming few days (the average of 10 runs of iozone for each option (options being native qla2xxx failver, native qla2xxx multibus, HP qla2xxx failover)). I'll post a summary of results here for those interested.

• Anyone know of a good way to sell used servers?

  - by RandyMorris

  We have a couple of servers we no longer need now that we are fully hosted on a managed host (rackspace). They were purchased for over $10,000 each but we realize that over time their monetary value drops. Anyone have suggestions or experience selling these in a proper way? They are dual xeon processor 2U rack mountable with 4+GB RAM, intel boards, 6x 72GB 15,000 RPM SCSI Drives with raid controller redundant power supply. We are in Southern California area. I can be more specific on any information if there is interest. I know there is ebay and the like but these servers are like the family dog that has to be given up and we are looking for a proper home for a fair price. I will end up auctioning it off if need be in the end though. Thanks in advanced for any help!

• How can I recover Google Chrome extensions, settings after a Linux crash?

  - by Norman Ramsey

  I'm running Google Chrome 5.0.307.11 (Official Build 39572) beta on Debian Linux (lenny) kernel version 2.6.26-2-686. The machine is a laptop (Lenovo Thinkpad X300) and sometimes it freezes, usually shortly after wakeup from sleep. The only cure is the power button, but when I restart my Google Chrome web browser after such an event, Settings on the Options menu revert to defaults. Chrome removes all the extensions from ~/.config/google-chrome/Default/Extensions, leaving me with no extensions. The set of "pages last open" is lost. I'd love to know how to poke at the file system in order to recover any or all of this information, especially my extensions. It is a pain to re-do everything by hand each time. How can I recover Google Chrome's extensions and settings after a Linux crash?

• How to control admission policy in vmware HA?

  - by John

  Simple question, I have 3 hosts running 4.1 Essentials Plus with vmware HA. I tried to create several virtual machines that filled 90% of each server's memory capacity. I know that vmware has really sophisticated memory management within virtual machines, but I do not understand how the vCenter can allow me even to power on the virtual machines that exceed the critical memory level, when the host failover can be still handled. Is it due to the fact that virtual machines does not use the memory, so that it is still considered as free, so virtual machines can be powered on ? But what would happen if all VMs would be really using the RAM before the host failure - they could not be migrated to other hosts after the failure. The default behaviour in XenServer is that, it automatically calculates the maximum memory level that can be used within the cluster so that the host failure is still protected. Vmware does the same thing ? The admission policy is enabled. Vmware HA enabled.

• Confirm disk is broken when it passes all diagnostics

  - by Halfgaar

  I have a system with a potentially broken disk, but the disk passes all manner of diagnostics. I have been unable to confirm that the disk is broken. What are my options? I could just replace the disk, but because this situation is very similar to another more severe situation I have (long story), I'd like to actually make a proper diagnosis as opposed to randomly binning hardware. The issue and history is this: I had a Debian Linux PC (500 MHz P3) acting as router, nagios and munin. It crashed every couple of weeks. No logs or dmesg could be obtained (because it's an old Compaq that only boots when you configure it as keyboardless, making connecting a keyboard later, once it's booted, impossible). At the time, I just replaced the computer with another Compaq (P4 2.4 GHz) because I thought the hardware was faulty. However, it still crashed every couple of weeks. the difference is that on this computer, I can still SSH into it. It gives all kinds of errors on hda. I'd like to confirm that the disk is broken, but nothing I do confirms this: SMART error logs shows no errors. Normally when a disk starts acting up, SMART my pass, but it still records a read-error in the error log. SMART self-test (smartctl -t long /dev/sda) completes without errors. re-allocated sector count (a tell-tale parameter) has been 31 all its life, even when the disk was still in use in my desktop PC years ago, and it still is. The figure never changed. dd if=/dev/sda of=/dev/null bs=4096 passes with flying colors. What else can I do to assess the health of the drive? Again, this is not about making this router fully functional again, this is a disk forensic question, because it just so happens that I have another server that potentially has the same problem, and knowing the answer to this will possibly help me greatly. For the record, below are logs and such.

• Is it common to have portable hard drive not recognize?

  - by lamwaiman1988

  I have a bad hard drive which could not be recognized by windows. If windows can recognize it, it could just be pure luck. There are better chance of it being recognize by plugging it at the usb back of the machine, rather than the front one. More interestingly, I have a usb cable which fork itself at one side ( i.e it has 2 heads at one side ). I can plug both heads to the machine and connect the portable hard drive on the other end of the usb cable? Can I get more voltage by doing this? I am guessing the front usb port doesn't have enough power. I am wondering if I buy a new portable usb hard drive, would it have easy read by plugging at the front usb port? I am not sure if I screw up the jumper connecting the front usb ports, but it is okay for other device such as usb stick and mouse.

• Is there a registry key change that will by-pass the Windows Domain Join Welcome page?

  - by user1256194

  I'm scripting some Windows Server 2008 R2 builds using Power Shell. Some software needs to be installed after the server has joined the domain. Since I want to automate everything, I'm looking to by-pass the domain controllers Welcome page using a registry hack script. I work for a large company and the Active Directory people are unwilling to change group policy. I figure if it's a registry key I can script the change, install the software, replace the key and reboot as the final step. Is there a registry key change that will by-pass the Domain Join Welcome page?

• Serial number not found, copy of Windows not genuine

  - by sara

  I have an HP-G71-340US notebook that I purchased 11/29/09. When I power it up, a black screen comes on that shows "serial number not found" and it also says that my copy of Windows 7 Home Basic is not genuine – but my computer came with Windows 7 Home Premium. In BIOS, my serial number is not shown either and I did pull out the little battery to reset it which allowed me to bypass the suddenly new locked BIOS that needed a password to enter. I'm sure this is a masterpiece created by my 6 or 9 yr old child while trying to play on my laptop. Can I fix these two problems?

• ReadyNAS issue with Google Apps?

  - by Jauder Ho

  The power went out (again) in my house today so I decided to set up some alerting. Since I have a ReadyNAS and the latest version of Raidinator seems to have SMTP TLS support, I figured I would try setting things up to email to a domain I have hosted on Google Apps. At this point, I have everything working IF I use a Gmail account but as soon as I switch to a Google Apps email address, it stops working and complains with smtpstatus=535 smtpmsg='535-5.7.1 Username and Password not accepted. Learn more at \n535 5.7.1 http://mail.google.com/support/bin/answer.py?answer=14257 30sm16076226wfd.23' errormsg='authentication failed (GNU SASL, method PLAIN)' exitcode=EX_NOPERM I'm wondering if anyone else has encountered this. Google's extremely aggressive captcha does not help but I am able to log in now without a captcha from a browser so I'm open to any ideas why the simple switch of a user/password combo that is supposed to work does not. I'm also attaching my config so that others can see how to set things up.

• How do I built a DIY NAS?

  - by Kaushik Gopal

  I'm looking for good, detailed instructions on how to build a DIY NAS (Network Access Storage). I'm planning on doing it cheap (old PC config + open source software). I would like to know: What hardware I need to built one What kind of hard-drive setup I should take (like RAID) Or any other relevant hardware related advices (power supply, motherboard etc...) What software I should run on it, both what OS and software to manage the contents effectively So the NAS is recognizable and accessible to my network I can make sure my Windows computers will recognize it (when using Linux distro's) I can access my files from outside my network I already did a fair bit of searching and found these links, but while these links are great they delve more on the hardware side. I'm looking for more instructions in the software side.

• Choosing between a dedicated and virtual dedicated server for my startup

  - by MarathonStudios

  I'm about to launch a startup site I've been working on for some time, and I'm just now looking over hosting plans. The site's main feature is fairly processor-heavy (a lot of text processing), so I probably need something other then shared hosting to ensure I don't get shut down for overusing resources. I would like to spend as little as possible on hosting until the site starts generating income, so under-$60/mo is my goal. One caveat is that I need a Windows box for this particular site, so it's harder to get a good deal. For that price, I can either get a bottom-tier dedicated (2gigs ram, pentium 4) or a middle-tier VPS (3gb RAM, a bit more traffic and HD) for a few bucks more per month. I had a bad experience with a low-end VPS a few months ago, so making sure that whatever I get can handle the basic traffic of a website as well as giving me what I need (extra processing power) is essential. Do you have any suggestions as to which way to go, or a certain hosting company you've worked with that you can recommend?

• Configure TV Capture card to not use external audio jack for TV audio output

  - by Adam D.

  I had this working with MythTV on Ubuntu 9.1. Then a power surge killed the motherboard. After replacing the motherboard, ram and cpu, the card does not produce any audio except through the output jack on the back of the card. I do not want to use a cable to go from the back of the card to the audio in on the built in sound card of the new mother board. FYI, the old motherboard did not have an on-board sound card. There was a separate audio card installed. There's some configuration that has to be done to have it work the same way again. I just have no idea where to start. This is regarding wintv hauppauge mythtv linux ubuntu 9.10 audio

• Compaq 610 fan is constantly on and noisy, base is fairly hot too

  - by Dave

  The fans on both of my HP Compaq 610s are constantly on and the base is fairly hot and I don't know if this is standard issue. HP assures me that this is unusual and that I should return them as DOA. Because both laptops have this problem, I'm thinking that this might be a design flaw rather than a one-off problem. I've updated the BIOS and using their recommended power settings. Am I missing something? Is there anything I can do to fix it?

• Computer and internet use on a boat?

  - by dlamblin

  Let's assume that I seriously would like to be able to use my computer as easily and as carefreely while on a boat as I do while at home. In short, if I were on a boat for extended periods, such as two weeks at a time and occasionally over a few days out of port (this would be a 2 person sailing vessel), what would my options be for power, durability, and of course, internet access? I want more than just email, as I will likely keep doing a tad of development, and will be looking at google earth from time to time. I am already assuming that we're going with some kind of laptop, maybe even a macbook pro 12". I personally feel that netbooks are underpowered. And the last computer that I got a boat-friendly rating for was a ZX Spectrum, which was before the internet, and was likely due to it's 12vdc-happiness.

• How much processor speed and cores do I need for these tasks?

  - by ajay

  I am planning to buy a new laptop as I find my current one very slow. My question here is specifically related to RAM size and CPU power. I will mostly be doing development (not much games). I would be dabbling in distributed computing, multithreaded and data intensive parallelizable tasks on multi-cores. For e.g. I would want to be able to Concurrent programming in Scala/Java/Clojure etc. and be able to see parallelization. Furthermore, I would want the RAM to be enough. But from a developer machine standpoint, do you think 4GB RAM and 2.53GHz Dual Core processor would be enough.

  This is only about networks you have seen personaly, not heared from others or seen on pictures at the web. Cables hanging from the ceiling lamps? Cables going trough culverts and other tubes? Switches and other equipment in the cleaner's closet? Cleaning lady's rags drying hanging from the cables? Key to the main node door possesed only by the janitor (or other non-tech and completely non-network-related guy)? Switches powered by foreign power adapters (cheaper and providing non-specified voltage or amperage)? All of this was in my old dormitory. Tell us about your bad experience.

• Mac Book Pro wakes up in my backpack

  - by J. Pablo Fernández

  This has happened to me twice: I press the power button on my Mac Book Pro, choose sleep, close it, unplug everything, confirm that is off (by pressing my ear to it) and put it in my bag. Some minutes later, the laptop wakes up by itself. Both times I caught it in time. The second time it was so hot I couldn't touch some parts -- it refused to actually wake up, and the screen was blank. Restarting it worked though. Any ideas what might be going on and/or how to prevent this? More details: It's a Mac Book Pro unibody 15" from 2009.

• Set certain WSUS updates to auto-install

  - by Nicolas

  We're running a WSUS server for the simple purpose of caching updates. Since we are a very small network of all "power users", we've got the domain group policy for WSUS updates on the clients set to prompt for download/install. i.e. We don't want updates to install without our knowledge. But there are a few cases where it would be nice to be able to set a certain update to auto-install. e.g. Windows Defender updates, Malicious Software Removal Tool, Outlook Junk Email Filter, etc. Basically all the silly little updates that you would always install anyway and don't require a restart. Is there a way to set the general policy to prompt for download/install, but auto-install certain regular updates? P.S. WSUS itself does have the facility to auto-approve certain updates. That part works. Facts & Figures: SBS 2003 domain Windows 7 Pro clients Windows XP Pro clients

• Skipping scheduled self-tests and predicting drive EOL

  - by Steve Madsen

  For a few weeks now, smartd has been reporting that it is skipping some of its scheduled self-tests on the weekends: Apr 24 18:29:32 calvin smartd[4758]: Device: /dev/sda, skip scheduled Offline Immediate Test; 40% remaining of current Self-Test. Apr 24 18:29:33 calvin smartd[4758]: Device: /dev/sdb, skip scheduled Offline Immediate Test; 50% remaining of current Self-Test. The drives in this RAID-1 array are set to run an offline test four times a day, a short self-test at 2am every day, and a long self-test on Saturdays at 2am. For some reason, it looks like the long self-test is taking longer, causing the other scheduled tests to be skipped. First question: is this a sign of likely drive failure? Then today, smartd reported that a self-test failed. Here is the output of smartctl -a /dev/sdb: smartctl version 5.38 [i686-pc-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Model Family: Seagate Barracuda 7200.8 family Device Model: ST3250823AS Serial Number: 3ND1GNBC Firmware Version: 3.03 User Capacity: 250,059,350,016 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 7 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Sun Apr 25 13:15:34 2010 EDT SMART support is: Available - device has SMART capability.

If Selective self-test is pending on power-up, resume after 0 minute delay. Given that this drive is about 4.5 years old, I am probably tempting fate by keeping it in service. SMART doesn't seem to get much respect as a reliable way to predict drive failure. What else can I use to get an early indication of drive failure?
