• Repair Windows 7 MBR with Hiren's Boot CD

  - by Joshua Robison

  I would like to repair my Windows 7 MBR using Hiren's Boot CD 15.1. I want to know the generic method, using this CD, to fix an MBR that is hypothetically "toast". This hypothetical HD is as follows: 100 MB MBR partition 60 GB Windows 7 system Let's imagine there is an empty 100 MB partition and the MBR is corrupt beyond repair or completely not there and my only option is Hiren's Boot CD.

• Bash script to create mass series of directories

  - by Volomike

  I need to create a Bash script to go into every user's home folder, seek out a wp-content folder, create a directory uploads under it, and then chmod 0756 uploads. How do I achieve this? I imagine I need to use find with a regexp/regex, and then tell it to run another bash script on the results.

• dovecot imap ssl certificate issues

  - by mulllhausen

  i have been trying to configure my dovecot imap server (version 1.0.10 - upgrading is not an option at this stage) with a new ssl certificate on ubuntu like so: $ grep ^ssl /etc/dovecot/dovecot.conf ssl_disable = no ssl_cert_file = /etc/ssl/certs/mydomain.com.crt.20120904 ssl_key_file = /etc/ssl/private/mydomain.com.key.20120904 $ /etc/init.t/dovecot stop $ sudo dovecot -p $ [i enter the ssl password here] it doesn't show any errors and when i run ps aux | grep dovecot i get root 21368 0.0 0.0 12452 688 ?

• How to manage Media Center Extender schedule from Media Center in Windows7

  - by Pangea

  I want to have several machines set up as digital signage displays and pull media (.pptx, video, images etc) from a centralized place. This is easy enough, but what I really need help doing is managing which extenders play specific media and the schedule from a Windows 7 x64 client hopefully within Media Center but I'm open to another management app. Is it possible to dictate the time and location each media is pushed to? I can use either a full machine running a full Win7 OS or a simple MC extender.

• Can I set up a separate RAID 5 devices?

  - by GregH

  I have a GIGABYTE GA-P55M-UD2 motherboard in my system (Windows 7 64 bit) and currently have a Western Digital SATA 10k RPM drive in it. Is it possible to add three more SATA drives to make a single RAID 5 device that is separate from the current 10k rpm drive that I have in it? Once I enable RAID for the SATA drives, I am not required to make all of the drives part of the RAID volume am I? I can have separate RAID'ed and non-RAID'ed volumes can't I?

• Windows 7 detects my 1 TB disk as a disk with only 31 MB space

  - by ZelluX

  I've added another 1 TB Western Digital disk on my computer (there is a disk with 250 GB already), and after booting to Windows 7, it recognise the disk, but in the Disk Management panel, it says the disk has only 31 MB TOTAL space, so is what it shows in the EVEREST information. And when I rebooted the computer and entered BIOS, it said the new disk has 0 MB disk capacity. Is there any way to fix this problem?

• sed: delete text between a string until first occurrence of another string

  - by Marit Hoen

  Imagine I have something like the following text: The quick brown fox jumps in 2012 and 2013 And I would wish to delete the part from "fox" including the four numbers but only in the first occurrence so I end up with: The quick brown and 2013 Something likes this...: echo "The quick brown fox jumps in 2012 and 2013" \ | sed "s/fox.*\([0-9]\{4\}\)//g" ...brings me: The quick brown So it removed everything including the last occurrence of the four numbers. Any ideas?

• Database cluster... without Master/Slave?

  - by RadiantHex

  Hi there! I'm wondering if it is possible to have a set of SQLdb servers to which data is written and have them replicate, avoiding conflicting information. I imagine that a Master/Slave structure would be mandatory, I would like to know if a system where servers have no hierarchy could support replication. Currently I'm using MySQL, but I would be happy to move to another database if needed. Any ideas? :)

• How to compact a registry hive?

  - by SLaks

  I'm using a (non-administrator) roaming profile, with a size limit of 4MB. As you can imagine, it is extremely difficult to stay within that size limit. I've noticed that NTUser.dat, which holds my HKEY_CURRENT_USER hive, is 2560KB, single-handedly using more than half of that limit. Is there any way to shrink the hive without administrator privileges? I don't mind losing any settings or preferences stored in it.

• Microsoft Visio missing shape templates

  - by Rolnik

  I'm using MS Visio 2003 Standard. When I first was using it 3 years ago, it would let you search a database of thousands of ready-made templates, which I think Microsoft hosted at their own website. Several months ago, these templates were no longer available. I'm looking for some kind of replacement for common computer architecture and digital circuits, as well as user interface mock-ups. Does anybody know where I can find an assortment of these 'shapes'?

• Low framerate on background apps

  - by user1698923

  My problem is that when a game is running in the foreground, in Full Screen mode, any applications on my second monitor (such as youtube videos, videos, not app specific) drop their frame-rate to about 2-3 FPS. It seems like some sort of power management option that I can't track down. As far as I can tell, it's not due to the GPU not being able to keep up. For instance, my PC can play League of Legends at about 280FPS when the framerate is uncapped. If i cap it at 60FPS using the in-game option, it has no affect on the performance of the background app. Summary Operating System Windows 8 Pro 64-bit CPU Intel Core i7 3820 @ 3.60GHz 42 °C Sandy Bridge-E 32nm Technology RAM 12.0GB Triple-Channel DDR3 @ 533MHz (7-7-7-20) Motherboard Gigabyte Technology Co., Ltd.

• alternative filesystems for SSD

  - by freedrull

  I am tired of watching fsck check my filesystem when my eeepc 901 shuts down abruptly due to a crash. I know that with a journaling filesystem, I won't have to wait for a check. However, I am well aware of the poor I/O performance of the SSD, so I can imagine using a journaling filesystem being even more frustrating, since there will be constant writes to the journal? I will buy a new laptop without such a crummy ssd someday but, is there anything I can do now, on the software side of things?

• Stack-based keyboard delay using Logitech MX3100 keyboard

  - by Mark S. Rasmussen

  I've been using a Logitech Cordless Desktop MX3100 keyboard for quite a while. I've never really had any problems, except for the occasional typo. I noticed however that I tended make the typo "Laod" instead of "Load", quite a bit more often than any other typos. As it started to get on my nerves, I decided to do some testing. What I found out was than when I write lowercase "load", I'd never make the typo. All uppercase, or just uppercase L, I'd make the typo quite often. My actual (very scientific) testing is probably best described by showing the output: moatmoatmoat MoatMoatMoat loatloatloat LaotLaotLaot loafloafloaf LaofLaofLaof hoathoathoat HoatHoatHoat hoadhoadhoad HoadHoadHoad lortlortlort LrotLrotLrot What i found out was that whenever shift was depressed, typing an uppercase "L" would induce a significant lag if the next character was an "o", compared to the lag of the any other key: High "o" lag: LoLoLoLoLoLo No "a" lag: LaLaLaLaLaLa No lag for neither "o" nor "a": lolololololo lalalalalala By realizing this I regained a slight bit of sanity as I knew I wasn't coming down with a case of Parkinsons. I was actually typing correctly, the lag just interpreted it wrongly. Now, what really bugs me is that I can't fathom how this is occurring. What I'm actually typing, in physical order, is this: L - o - a - d, and yet, the "a" is output before the "o", even though "o" was pressed before "a". So while the keyboard is processing the "Lo" combo, the "a" gets prioritized and is inserted before the "o" is done processing, resulting in Laod instead of Load. And this only happens when typing "Lo", not when typing lowercase "lo". This problem could stem from the keyboard hardware, the receiver hardware or the keyboard software driver. No matter the fault location however, I can't imagine how this could be implemented as anything but a FIFO queue. A general delay, sure, I could live with that, albeit I'd be irritated. But a lag affecting different keys differently, and even resulting in unpredictable outcome - that just doesn't make any sense. I've solved the problem by just switching to a wired keyboard. I just can't shake it off me though; what kind of bug/error/scenario would result in a case like this? Edit: It's been suggested that I stop drinking Red Bull and stick to water instead. While that may actually help solve the issue, I'm really not looking for a solution as such. I'm more interested in an explanation of how this could happen, as I can't imagine any viable technical solution that could result in this behavior.

• Where can I find what license key was used in my installed copy of Visual Studio 2008?

  - by sunpech

  I have legitimate copies of Visual Studio 2008 installed on several computers, each with different license keys. I cannot remember what key was used on each install. Where in the registry can I find what license key was used for that PC's Visual Studio 2008 installation? I would imagine that it is in the registry somewhere.

• Diagnosing and debugging LAN congestion / connection issues

  - by John Weldon

  What are the top N tools / methodologies used to diagnose and repair network issues? Given a LAN, for example, where users are able to consistently ping an outside server, but any data intensive connections are flaky; how would you begin solving the network issues? I imagine issues like congestion, bandwidth constraints, throughput constraints, etc. are all factors, but I don't know how to diagnose those issues. I'm especially interested in LAN environments (rather than WAN)

• Nagios vs Splunk

  - by dan_vitch

  I am looking to implement log tracking at my current company. After some research it seems Nagios and Splunk are the two best options. I was wondering if there is a consensus with which is better. I understand that Splunk can be quite pricey if the non-free version is used. That being said I can imagine the answer to my question will be "If you have the money use Splunk, if not use Nagios"

• Will HDCP cause problems with a MacBook Pro using a VGA projector?

  - by Andrew Grimm

  I'm planning on using a MacBook Pro with a projector that only has a VGA input (through the MBP's Mini DisplayPort and a Mini DisplayPort to VGA converter). Will this have problems with HDCP (High-bandwidth Digital Content Protection), either under Snow Leopard or Windows XP? I'll only be showing other people's photos, user-generated movies or PowerPoint slides. The MacBook Pro was purchased from Apple new in December 2009.

• How can I archive a 30GB file?

  - by Joel Coehoorn

  I have a zip 30GB zip file containing an archive of digital materials available in the school library that I want to burn to dvd. Of course, 30Gb is far too large for a single dvd and the content is already zipped. I'm open to ideas, but leaning towards suggestions that will help me automatically spread the file over multiple dvds, including a simple program to stitch it back together again later.
