• What was the first consumer-oriented hardware/software solution?

  - by Maksee

  We all know the story of the personal computer as a consumer-oriented product. But I just thought that real end user solution should have appeared before that time. So a product that was probably expensive, but allowed using it as a service charging for it, for example computer-terminal for transport time-table access or game machine. On the other site, the video terminals as we know them appeared not so long ago. So if there was something like this, this could be hardware/software most likely offering no interactivity, but probably printing some information based on user actions.

• ubuntu 9.10 installer doesn't recognize the hard drive

  - by dan

  I downloaded Ubuntu 9.10 x86_64 and am trying to install it on a fairly modern system with a Gigabyte GA-MA770-UD3 motherboard. Ubuntu 9.04 installed fine and still will when I stick that disc in, but 9.10 doesn't see my hard drive (western digital 250GB). If I boot from the disc, I can install gparted and it does recognize the drive, but when I try to start the install process from the live disc, Ubuntu again doesn't recognize the hard drive. I checked /var/log/messages and see this: Nov 12 17:28:08 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was bad, boot with 'nodmraid'. Nov 12 17:28:08 ubuntu activate-dmraid: Enabling dmraid support Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required.

I checked my BIOS, SATA is enabled and is set to IDE mode, so there shouldn't be software RAID, but nonetheless, I added nodmraid to the boot line and tried again. It still doesn't recognize the drive. I checked /var/log/messages again and now see this: Nov 12 17:49:38 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was boad, boot with 'nodmraid'. Nov 12 17:49:38 ubuntu activate-dmraid: Enabling dmraid support Nov 12 17:49:38 ubuntu activate-dmraid: WARNING: dmraid disabled by boot option Nov 12 17:49:38 ubuntu activate-dmraid: WARNING: dmraid disabled by boot option Any ideas on things to try? I've tried all of the various BIOS settings for SATA. IDE,RAID, etc. Nothing seems to work.

• What are the industry metrics for average spend on dev hardware and software? [on hold]

  - by RationalGeek

  I'm trying to budget for my dev shop and compare our budget items to industry expectations. I'm hoping to find some information on what percentage of a dev's salary is generally spent on tooling, both hardware and software. Where can I find such information? If instead there is a source that looks at raw dollars that is useful, too. I can extrapolate what I need from that. NOTE: Your anecdotal evidence from your own job will not be very helpful. I'm looking for industry average statistics from a credible source. EDIT: I'm reluctant to even keep this question going based on the passionate negative responses of commenters, but I do think this is valuable information (assuming anyone will care to answer) so let me make one attempt to clarify why I'm looking for this information, and then leave it at that. I'm not sure why understanding and validating my motives is a necessary step to providing the information, but apparently that is the case, so I will do my best. Firstly, let me respond to the idea that us "management types" shouldn't use these types of metrics to evaluate budgets. I agree in part. Ideally, you should spend whatever is necessary on developers in order to keep them fully happy and productive. And this is true of all employees. However, companies operate in a world of limited resources, and every dollar spent in one area means a dollar not spent in another. So it is not enough to simply say "I need to spend $10,000 per developer next year" without having some way to justify that position. One way to help justify it is to compare yourself against the industry. If it is the case that on average a software shops spends 5% (making up that number) of their total development budget (salaries being the large portion of the other 95%, for arguments sake), and I'm only spending 3%, it helps in the justification process. So, it is not my intent to use this information to limit what I spend on developers, but rather to arm myself with the necessary justification to spend what I need to spend on developers to give them the best tools I can. I have been a developer for many years and I understand the need for proper tooling. Next, let's examine the idea that even considering the relationship between a spend on developer salaries and developer tooling is ludicrous and should be banned from budgetary thinking. As Jimmy Hoffa put it in their comment, it's like saying "I'm going to spend no more than 10% of median employee salary on light bulbs and coffee from now on.". Well, yes, it is like saying that, and from a budgeting perspective, this is a useful way to look at things. If you know that, on average, an employee consumes X dollars of coffee a year, then you can project a coffee budget based on that. And you can compare it to an industry metric to understand where you fall: do you spend more on coffee than other companies or less? Why might this be? If you are a coffee supply manager, that seems like a useful thought process. The same seems to hold true for developers. Now, on to the idea that I need to compare "apples to apples" and only look at other shops that are in the same place geographically, the same business, the same application architecture, and the same development frameworks. I guess if I could find such a statistic that said "a shop that is exactly identical to yours spends X on developer tooling" it would be wonderful. But there is plenty of value in an average statistic. Here's an analogy: let's say you are working on a household budget and need to decide how much to spend on groceries. Is it enough to know that the average consumer spends 15% on groceries and therefore decide that you will budget exactly 15%? No. You have to tweak your budget based on your individual needs and situation. But the generalized statistic does help in this evaluation. You can know if your budget is grossly off from what others are doing, and this can help you figure out why this is. So, I will concede the point that it would be better to find statistics that align to my shop, though I think any statistics I could find would be useful for what I'm doing. In that light, let's say that my shop is mostly focused on ASP.NET web applications. That doesn't map perfectly to reality because large enterprises have very heterogenous IT environments. But if I was going to pick one technology that is our focus that would be it. But, if you were to point me at some statistics that are related to a Linux shop doing embedded Java applications, I would still find it useful as a point of comparison. SUMMARY: Let me try to rephrase my question. I'm trying to find industry metrics on how much dev shops spend on developer tooling, both hardware and software. I don't so much care whether it is expressed as a percentage of total budget or as X dollars per dev or as Y percentage of salary. Any metric would be useful. If there are metrics that are specific to ASP.NET dev shops in the Northeast US, all the better, but I would be happy to find anything.

• Can you tell whether I have a hardware or software problem with a DVD-ROM drive?

  - by user8934

• Adding a Network Loopback Adapter to Windows 8

  - by Greg Low

  I have to say that I continue to be frustrated with finding out how to do things in Windows 8. Here's another one and it's recorded so it might help someone else. I've also documented what I tried so that if anyone from the product group ever reads this, they'll understand how I searched for it and might try to make it easier.I wanted to add a network loopback adapter, to have a fixed IP address to work with when using an "internal" network with Hyper-V. (The fact that I even need to do this is also painful. I don't know why Hyper-V can't make it easy to work with host system folders, etc. as easily as I can with VirtualPC, VirtualBox, etc. but that's a topic for another day).In the end, what I needed was a known IP address on the same network that my guest OS was using, via the internal network (which allows connectivity from the host OS to/from guest OS's).I started by looking in the network adapters areas but there is no "add" functionality there. Realising that this was likely to be another unexpected challenge, I resorted to searching for info on doing this. I found KB article 2777200 entitled "Installing the Microsoft Loopback Adapter in Windows 8 and Windows Server 2012". Aha, I thought that's what I'd need. It describes the symptom as "You are trying to install the Microsoft Loopback Adapter, but are unable to find it." and that certainly sounded like me. There's a certain irony in documenting that something's hard to find instead of making it easier to find. Anyway, you'd hope that in that article, they'd then provide a step by step example of how to do it, but what they supply is this: The Microsoft Loopback Adapter was renamed in Windows 8 and Windows Server 2012. The new name is "Microsoft KM-TEST Loopback Adapter". When using the Add Hardware Wizard to manually add a network adapter, choose Manufacturer "Microsoft" and choose network adapter "Microsoft KM-TEST Loopback Adapter".The trick with this of course is finding the "Add Hardware Wizard". In Control Panel -> Hardware and Sound, there are options to "Add a device" and for "Device Manager". I tried the "Add a device" wizard (seemed logical to me) but after that wizard tries it's best, it just tells you that there isn't any hardware that it thinks it needs to install. It offers a link for when you can't find what you're looking for, but that leads to a generic help page that tells you how to do things like turning on your printer.In Device Manager, I checked the options in the program menus, and nothing useful was present. I even tried right-clicking "Network adapters", hoping that would lead to an option to add one, also to no avail.So back to the search engine I went, to try to find out where the "Add Hardware Wizard" is. Turns out I was in the right place in Device Manager, but I needed to right-click the computer's name, and choose "Add Legacy Hardware". No doubt that hasn't changed location lately but it's a while since I needed to add one so I'd forgotten. Regardless, I'm left wondering why it couldn't be in the menu as well.Anyway, for a step by step list, you need to do the following:1. From Control Panel, select "Device Manager" under the "Devices and Printers" section of the "Hardware and Sound" tab.2. Right-click the name of the computer at the top of the tree, and choose "Add Legacy Hardware".3. In the "Welcome to the Add Hardware Wizard" window, click Next.4. In the "The wizard can help you install other hardware" window, choose "Install the hardware that I manually select from a list" option and click Next.5. In the "The wizard did not find any new hardware on your computer" window, click Next.6. In the "From the list below, select the type of hardware you are installing" window, select "Network Adapters" from the list, and click Next.7. In the "Select Network Adapter" window, from the Manufacturer list, choose Microsoft, then in the Network Adapter window, choose "Microsoft KM-TEST Loopback Adapter", then click Next.8. In the "The wizard is ready to install your hardware" window, click Next.9. In the "Completing the Add Hardware Wizard" window, click Finish.Then you need to continue to set the IP address, etc.10. Back in Control Panel, select the "Network and Internet" tab, click "View Network Status and Tasks".11. In the "View your basic network information and set up connections" window, click "Change adapter settings".12. Right-click the new adapter that has been added (find it in the list by checking the device name of "Microsoft KM-TEST Loopback Adapter"), and click Properties.

• Should Windows Multipoint Server stations on individual video cards support hardware video acceleration?

  - by villares

  I've set up a test machine with multiple PCI-e nVidia GF440 Video cards and installed Windows Multipoint Server 2011. I use the same kind of hardware set up with a BeTwin multiseat solution to create a class lab for Google SketchUp teaching (highly OpenGL dependent) and it works ok. On the Multipoint Windows test machine the drivers seem to be installed OK but I don´t seem to get any hardware video acceleration. Is this a intrinsic limitation of this solution or am I doing something wrong?

• Can I get Raid disk status by using PS?

  - by David.Chu.ca

  I have a HP server with Raid 5. Port 0 and 1 are used for data & OS mirroring. The software come with the Raid 5 is Intel Matrix Storage Manager and there is manager console as windows based api to view all the ports, including their status. Now they are all in Normal status. I am not sure if the OS/Windows has some APIs or .Net classes to access raid ports and get their status? If so, how can I use PS to get the information? Do I have to reference to the dlls provided by the Intel Matrix Storage Manager if not? Basically, I would like to write a PS script to get read status. In case any of port disk is not normal, a message will be sent out by growl protocol.

• mdadm raid5 recover double disk failure - with a twist (drive order)

  - by Peter Bos

  Let me acknowledge first off that I have made mistakes, and that I have a backup for most but not all of the data on this RAID. I still have hope of recovering the rest of the data. I don't have the kind of money to take the drives to a recovery expert company. Mistake #0, not having a 100% backup. I know. I have a mdadm RAID5 system of 4x3TB. Drives /dev/sd[b-e], all with one partition /dev/sd[b-e]1. I'm aware that RAID5 on very large drives is risky, yet I did it anyway. Recent events The RAID become degraded after a two drive failure. One drive [/dev/sdc] is really gone, the other [/dev/sde] came back up after a power cycle, but was not automatically re-added to the RAID. So I was left with a 4 device RAID with only 2 active drives [/dev/sdb and /dev/sdd]. Mistake #1, not using dd copies of the drives for restoring the RAID. I did not have the drives or the time. Mistake #2, not making a backup of the superblock and mdadm -E of the remaining drives. Recovery attempt I reassembled the RAID in degraded mode with mdadm --assemble --force /dev/md0, using /dev/sd[bde]1. I could then access my data. I replaced /dev/sdc with a spare; empty; identical drive. I removed the old /dev/sdc1 from the RAID mdadm --fail /dev/md0 /dev/sdc1 Mistake #3, not doing this before replacing the drive I then partitioned the new /dev/sdc and added it to the RAID. mdadm --add /dev/md0 /dev/sdc1 It then began to restore the RAID. ETA 300 mins. I followed the process via /proc/mdstat to 2% and then went to do other stuff. Checking the result Several hours (but less then 300 mins) later, I checked the process. It had stopped due to a read error on /dev/sde1. Here is where the trouble really starts I then removed /dev/sde1 from the RAID and re-added it. I can't remember why I did this; it was late. mdadm --manage /dev/md0 --remove /dev/sde1 mdadm --manage /dev/md0 --add /dev/sde1 However, /dev/sde1 was now marked as spare. So I decided to recreate the whole array using --assume-clean using what I thought was the right order, and with /dev/sdc1 missing. mdadm --create /dev/md0 --assume-clean -l5 -n4 /dev/sdb1 missing /dev/sdd1 /dev/sde1 That worked, but the filesystem was not recognized while trying to mount. (It should have been EXT4). Device order I then checked a recent backup I had of /proc/mdstat, and I found the drive order. md0 : active raid5 sdb1[0] sde1[4] sdd1[2] sdc1[1] 8790402048 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/4] [UUUU] I then remembered this RAID had suffered a drive loss about a year ago, and recovered from it by replacing the faulty drive with a spare one. That may have scrambled the device order a bit...so there was no drive [3] but only [0],[1],[2], and [4]. I tried to find the drive order with the Permute_array script: https://raid.wiki.kernel.org/index.php/Permute_array.pl but that did not find the right order. Questions I now have two main questions: I screwed up all the superblocks on the drives, but only gave: mdadm --create --assume-clean commands (so I should not have overwritten the data itself on /dev/sd[bde]1. Am I right that in theory the RAID can be restored [assuming for a moment that /dev/sde1 is ok] if I just find the right device order? Is it important that /dev/sde1 be given the device number [4] in the RAID? When I create it with mdadm --create /dev/md0 --assume-clean -l5 -n4 \ /dev/sdb1 missing /dev/sdd1 /dev/sde1 it is assigned the number [3]. I wonder if that is relevant to the calculation of the parity blocks. If it turns out to be important, how can I recreate the array with /dev/sdb1[0] missing[1] /dev/sdd1[2] /dev/sde1[4]? If I could get that to work I could start it in degraded mode and add the new drive /dev/sdc1 and let it resync again. It's OK if you would like to point out to me that this may not have been the best course of action, but you'll find that I realized this. It would be great if anyone has any suggestions.

• need advice for storing data setup hardware for client with 80TB per year of data footprint increase

  - by dasko

  hi everyone, i currently have a client that will be adding replicated data from satellite locations in the number of approximately 80TB per year. with this said in year 2 we will have 160TB and so on year after year. i want to do some sort of raid 10 or raid 6 setup. i want to keep the servers to approximately 4u high and rack mounted. all suggestions welcome on a replication strategy. we will be wanting to have one instance of the data in house and the other to be co-located (any suggestions on co-locate sites too?). the obvious hardware will be something like a rack mount server with hot swap trays and dual xeon based type processors. the use of the data is for archives of information, files will be made up of small file sizes. i can add or expand to this question if it is too vague. thanks for looking.

• Server 2012 Storage Pools, Raid Controller... can the Storage Pool deal with it?

  - by TomTom

  Before trying it out - I don't find any documentation. Given that Storage Pools have serious performance problems with parity, and do not rebalance data at the moment when you add discs, my preferred way to use them would be as think provisioned space, ISCSI targets - with every "Pool" running against 1 RAID that comes from a Raid controller (who also introduces SSD read and write caching - another thing missing from Storage Pools). The main question is - how does a Storage Pool handle the change in the underlying disc that can happen? I mostly talk about OCE (Online Capacity Expansion), where a disc after an expansion suddenly reports a larger space. Standard Windows allows you to use this additional space (and expand the partitions). How does a storage pool handle it?

• I love programming but i also want to learn hardware. [closed]

  - by user167082

  I like programming so much, i did it since i was 10, and i believe that studying computer science will make a lot of money as well as i love it. However I also want to learn hardware. I don't only want to do programming all the time without knowing the architecture of device that i program. I asked my teacher, and she said that if I get into computer science, i won't learn anything about hardware, is it true?(She graduated from u-dub) In the other hand, my math teacher told me to get into electrical engineering, since it also contain programming. The thing is that i want to emphasize my study to programming while learning some about hardware. What is major that suits me the best? Can i take some hardware courses if I get into computer science major? Thanks a lot.

• Is it reasonable to make a RAID-1 array with a ram disk and a physical disk to maximize read performance and protect data?

  - by Petr Pudlák

  In one of the answers on SO (I forgot which one) I've seen a suggestion to make a RAID-1 array composed of a RAM disk and a physical partition. By adding the physical partition with --write-mostly and enabling --write-behind the system should read everything instantly from the RAM disk but still save all data to the physical partition so that the data are preserved and the RAID array can be assembled again after reboot. Is such a setup reasonable? Will it perform any better in some scenario than having just the physical partition and perhaps tweaking the kernel to favor disk cache (swappiness and vfs_cache_pressure)?

• Why does my game loop speed vary on different platforms with the same hardware?

  - by Sri Harsha Chilakapati

  I've got a serious issue with my game loop. This loop varies in time with the platform and with the same hardware. This is a list of FPS achieved: - Windows ======= 140 to 150 - Linux ======= 120 to 125 - Windows(WINE) ======= 125 to 135 And since my game loop is fixed timestep, the speed of the game is not stable. Here's my game loop. public final void run() { // Initialize the resources Map.initMap(); initResources(); // Start the timer GTimer.startTimer(); GTimer.refresh(); long elapsedTime = 0; // The game loop while (running) { // Update the game update(elapsedTime); if (state == GameState.GAME_PLAYING) { Map.updateObjects(elapsedTime); } // Show or hide the cursor if (Global.HIDE_CURSOR) { setCursor(GInput.INVISIBLE_CURSOR); } else { setCursor(Cursor.getDefaultCursor()); } // Repaint the game and sync repaint(); elapsedTime = GTimer.sync(); Toolkit.getDefaultToolkit().sync(); } } The timer package How could I improve it?

• Sd card bigger than 2gb is not recognized in ubuntu 12.04

  - by dex1

  When I insert a card up to 2gb it is immediately seen by the system but if try it with bigger one it's not seen.

• How to Add Proprietary Drivers to Ubuntu 10.04

  - by Matthew Guay

  Does the hardware on your Ubuntu system need proprietary drivers work at peak performance?  Today we take a look how easy version 10.04 makes it to install them. Ubuntu 10.04 finally automatically recognizes and installs drivers for most hardware today, it even recognized and configured Wi-Fi drivers correctly every time in our tests.  This is in contrast to the past, when it was often difficult to get hardware to work in Linux.  However, most video cards still need proprietary drivers from their manufacturer to get full hardware video acceleration. Even though Ubuntu doesn’t include any non-open source components, it still makes it easy to install proprietary drivers if you wish.  When you first install and boot into Ubuntu, you may see a popup informing you that “restricted” drivers are available. You may see a notification asking you if you’d like to install optional drivers from your graphics card manufacturer when you try to enable advanced desktop effects.  Click Enable to directly install the drivers right there. Or, you can select the tray icon from the first popup, and click Install drivers. Alternately, if the tray icon has disappeared, click System, then Administration, and select Hardware Drivers.   This will open a dialog showing all the proprietary drivers available for your system, which may include drivers for your video card and other hardware depending on your computer.  Select the driver you wish to install, and click Activate. Enter your password, and then Ubuntu will download and install the driver without any more input.  After installation you may be prompted to reboot your system. Now, you should be able to take full advantage of your hardware, including fancy desktop effects with hardware acceleration. If you ever wish to remove these drivers, simply re-open the drivers dialog as above, select the driver, and click Remove.  Once again, a reboot may be required to finish the process. Conclusion Ubuntu has definitely made it easier to use Linux on your desktop computer, no matter what hardware you have.  If your video card or other hardware require proprietary drivers, it makes them available and simple to install.  And, best of all, all of your drivers stay updated with your software updates, so you can be sure you’re always running the latest.

• If I can take a screen capture of a graphical anomaly, can it still be a hardware issue?

  - by Jay Carr

  I have a strange graphical anomaly going on my iMac right now (green and magenta boxes are appearing sporadically), I'm slowly trying to work through different possibilities but I thought I'd start with the basics: Can a graphical anomaly that I can screen capture still be a hardware issue? I know, it seems really obvious. If it's hardware, it should show up well after the operating system has had it's say. And since the operating system is (I assume) doing the screen capture, it seems like it shouldn't see the anomaly unless the problem is software in nature. But, as I've researched this problem I see a lot of people taking their computers in to service people for hardware issues and Apple then resolving said issue. To further complicate things, I also have Windows 8 installed via bootcamp, and the issues seems to be showing up there as well. Anyway, it feels like it must be a driver issue, since I assume that's what the two OSes have in common, but...I thought I'd come here for some disambiguation. In my case, yes, I can screen capture the anomaly (at least in OSX I can), so I assume it's somehow a software (or driver) issue. But I wanted to double check because the internet is being ambiguous...

• How to set Grub to automatically load Xen kernel

  - by Cerin

  How do you configure Grub to automatically use the Xen kernel under Ubuntu 11.10? No matter what I do, it loads the first menuentry. The only way I can get it to load Xen is to manually select the kernel, which I can't do if I have to reboot the server remotely, or there's a power failure and the machine automatically boots up when power's restored, etc. It's driving me nuts. In my /boot/grub/grub.cfg, the Xen kernel is at index 4 (i.e. it's the 5th menuentry). So I've tried: Setting GRUB_DEFAULT=4, and running sudo update-grub Setting GRUB_DEFAULT=saved and GRUB_SAVEDEFAULT=true, and running sudo update-grub Setting GRUB_DEFAULT="Ubuntu GNU/Linux, with Xen 4.1-amd64 and Linux 3.0.0-16-server", and running sudo update-grub None of these work. It continues to load the first menuentry, which is "Ubuntu, with Linux 3.0.0-16-server". Below is my current /boot/grub/grub.cfg. What am I doing wrong? # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN

• Hardware for a home server running Windows Server 2008 R2 Hyper-V or Microsoft Hyper-V Server 2008 R2

  - by David Hayes

  Hi, I'm planning to build a server to do the following Act as a file server (videos, pictures music) Run Squeezebox server Run Zune Software to allow wireless syncing to Windows Phone 7 I'd also like to aim for Low power usage (i'd settle for less than the 90-100Watts I'm using atm Flexibility, I might want to add a web server or sharepoint or... Something I can learn/test on, work is mainly a Windows shop but I do have Linux experience too I'd like to take a look at App-V (application virtualization) too I'd like it to cost less than $1000 Quiet would be nice but not essential (it'll be in the basement) I'm thinking of getting a technet subscription to get access to Windows Server 2008 R2 at a reasonable price ($199) So my plan was this Get a bunch of 2TB Caviar green drives to RAID up (RAID 1 or 6 probably) Get a Quad core CPU (Intel i5/i7 probably) Install a Hypervisor Install w2k8 R2 Storage Server for a NAS Install Windows 7 Pro to run Zune/Squeeze box Install any other machines I want to play with Questions Can anyone see any issues with this or have any better ideas? Do you think I'd need an i7 over an i5? Is 4 cores enough/too much? Can anyone sugest a nice, reasonably priced case that will hold 6-8 drives and stay cool Should I wait for Sandy Bridge parts?

• Filtering SQLAlchemy query on attribute_mapped_collection field of relationship

  - by bsa

  I have two classes, Tag and Hardware, defined with a simple parent-child relationship (see the full definition at the end). Now I want to filter a query on Tag using the version field in Hardware through an attribute_mapped_collection, eg: def get_tags(order_code=None, hardware_filters=None): session = Session() query = session.query(Tag) if order_code: query = query.filter(Tag.order_code == order_code) if hardware_filters: for k, v in hardware_filters.iteritems(): query = query.filter(getattr(Tag.hardware, k).version == v) return query.all() But I get: AttributeError: Neither 'InstrumentedAttribute' object nor 'Comparator' object associated with Tag.hardware has an attribute 'baseband The same thing happens if I strip it back by hard-coding the attribute, eg: query.filter(Tag.hardware.baseband.version == v) I can do it this way: query = query.filter(Tag.hardware.any(artefact=k, version=v)) But why can't I filter directly through the attribute? Class definitions class Tag(Base): __tablename__ = 'tag' tag_id = Column(Integer, primary_key=True) order_code = Column(String, nullable=False) version = Column(String, nullable=False) status = Column(String, nullable=False) comments = Column(String) hardware = relationship( "Hardware", backref="tag", collection_class=attribute_mapped_collection('artefact'), ) __table_args__ = ( UniqueConstraint('order_code', 'version'), ) class Hardware(Base): __tablename__ = 'hardware' hardware_id = Column(Integer, primary_key=True) tag_id = Column(String, ForeignKey('tag.tag_id')) product_id = Column(String, nullable=True) artefact = Column(String, nullable=False) version = Column(String, nullable=False)

• How can I troubleshoot a "Hardware Malfunction" blue screen?

  - by AaronSieb

  My computer has suddenly started crashing to a blue screen with the following text: hardware malfunction call your hardware vendor for support *the system has halted* The crash occurs randomly during normal use. I have thus far always been able to reproduce it by transferring the contents of a large folder... But I'm not sure if this is caused by the file transfer, or simply because the transfer takes long enough for something else to trigger it. A bit about my hardware I have an dual core Intel CPU, and Asus motherboard. Video card is by nVidia, and connects via PCIe. My hard drives are in pairs, and connect via SATA to a RAID controller on the motherboard. They are configured to use a RAID0 configuration. What I've tried so far There is nothing in the Windows Event Log. WhoCrashed was unable to find any crash records. ScanDisk runs to completion (it launches prior to Windows load) and reports no errors. MemTest reports no errors (to 200% coverage). System temperatures are in the range of 40 to 50 degrees Celsius, with video card temperatures in the range of 60 to eighty degrees Celsius. I have stripped the system down to a minimal configuration (hard drive, video card, one memory module, motherboard, CPU, power supply). The problem still occurrs. However, this has allowed me to rule out a few components: It is not the video card because the problem still occurred after replacing the video card another one I had on hand. It is not the hard drive or anything software related because the problem occurred after a fresh installation of Windows on a replacement hard drive. It is not the hard drive cables because I replaced those with new ones and still had the problem. It is not the power supply because the problem still occurred after replacing the power supply with another one I had on hand. It is probably not the memory because I've tried three different memory modules in three different memory slots and was still able to replicate the issue. Is there anything I can do to confirm what's causing the issue? At the moment it seems as though it must be either the motherboard or CPU, but those are both difficult components to replace... In addition, both components are relatively new (two to three years old). I will gladly edit in any additional information I can get my hands on, and/or focus the question as I can find more details...

• Is there a test to see if hardware virtualization (vmx / xvm) are presently enabled within a Linux session?

  - by Dr. Edward Morbius

  I'm writing procedures for configuring VirtualBox support for 64-bit SMP guests, which requires hardware virtualization suppot (VTx/Intel, AMD-V/AMD). I have successfully configured this myself, however I'd like the procedure to be clear. sed -ne '/^flags/s/^.*: //p' /proc/cpuinfo | egrep -q '(vmx|svm)' && echo Has hardware virt || echo No HW virt ... shows if the CPU is capable. I've still got to go enable the feature in BIOS. Any way to test from within Linux to see that this is no or not? Thanks.

• What are the minimum hardware requirements for the latest version of Android Jelly Bean OS?

  - by Stom

  I searched around, and there's no information that points exactly to the suggested, minimum, or otherwise dated information containing specifications on this. I want to install a newer version of Android on an older ZTE-X500 MetroPCS smartphone. However, I'd like to know the backwards compatibility in regards to using a newer featured OS with lackluster, limited hardware compared to today's smartphones, such as Galaxy S4. However, I still wish to do this. If Jelly Bean is too demanding, I will set up Honeycomb, or get a modified Honey Comb ROM, or tweak the source to my preferences. However, nothing outlines the specifics of the "system requirements" it suggests for optimum performance, such as RAM, processor speed, processor features, and/or any other features, like DMA, video circuit advancements, and/or sound and special hardware requirements noted as well. Please, if you will, point me to a source that mentions this, and please tell do not link me to any PDF file formats. Thank you. PS: I'm a computer programmer.

• Why is windows 7 marking all my extra RAM as "hardware reserved"?

  - by pinkmuppet

  I have a new HP Z800 Workstation, running Windows 7 Enterprise 64 bit. The machine has 4GB of RAM -- windows reported 1.99GB available, 2GB was "hardware reserved". I added another 2 GB and windows reports that there is 6GB of physical RAM, but now 4GB is "hardware reserved". The BIOS sees the full RAM amount as well. The video card is an nVida Quadro FX 580, so it shouldn't be using any shared memory at all. whats going on? Z800 Specs are here.
