• Strip my windows NTFS disk of all ACLs

  - by Alain Pannetier

  When you purchase a windows PC nowadays, you don't actually "own" the whole disk... There are so many ACLs on each folder that there are portions of it you actually can access only through a complex sequence of actions requiring skills well beyond the average PC user. You have to drill down to deeply buried dialog boxes accessible through concealed buttons. You have to understand at which level of the hierarchy you have to take ownership, remove ACLs etc... Yet when you think of it, that's your PC, that's what the "P" of PC originally stand for... So I'm toying with the idea of just stripping the disk of all ACLs I just purchased and leave standard file protections do the basic protection work... Just like previous century Windows used to do... (before I chmod -R 777 ;-) Has anybody done that already and nevertheless survived in reasonably good shape for a reasonable amount of time ? Any technical advice to do that ? Powershell script ? basic script using iCACLS ?

• nVidia driver is not installed for x64 Windows 7 (Vaio VGN-SZ460N)

  - by Sergey Osypchuk

  I just upgraded memory to 4GB for Sony Vaio VGN-SZ460N laptop and trying to install Windows 7 x64. All works fine with default drivers, except video - I am not able to set resolution more than 1024x768. Technical specification says that this model is using: Chipset : Intel® 945GM Processor : NVIDIA® GeForce® Go 7400 notebook graphics processing unit (GPU) and Intel® Graphics Media Accelerator 950 I was trying to use Intel 945GM driver, for Windows 7 Ultimate x64 and get error: This computer does not meet the mininum requirements for installing the software Also, I was trying to download nVidia GeForce Go 7400 x64 but it says that there is no compatible hardware. Actually, it has disclaimer that those drivers doesn't work for Sony vaio and recomendation to use OEM website. Sony website has only 32-bit version of driver which says that it cannot be installed and x64 should be used... Any ideas?

• Does a USB to RJ-45 console cable exist?

  - by Carl Flippin

  I am aware of the RJ-45 to DB9 adapter commonly used on cisco routers to access console. I am aware of the USB to DB9 adapters to allow laptops without serial to get a serial port. I am looking for a USB to RJ-45 adapter so I don't have to chain two adapters together. I have searched everywhere but even the pre-packaged solutions seem to have the two adapters chained together. Does such a thing exist? If it doesn't is there some technical reason it cannot? It seems like a manufacturer would just have to wire the DB9 end of the USB adapter differently and it would work just fine plugged straight into the console port of the router.

• How can I tag sequences inside videos?

  - by Antoine

  For example, let's say I find a sequence in a WWDC session (Apple videos) that explains a technical point very well. I would like to be able to store the exact range in the video, tag it with keywords, and manage all that information. And when I want to share this information, I could simply export to a plain English sentence: "Have a look at the video named …". It would be great to be able to launch a video player for local videos and go straight to the beginning of the sequence.

• How do I get Windows 7 wallpaper to display the company logo properly?

  - by David Silva Smith

  Windows 7 is not displaying our company background properly. Curves show pixelation and straight lines are jagged. I'm working with a scalable vector graphics (SVG) image that I've exported to the same resolution (pixel dimensions, to be technical) as the desktop, which is 1440x900. I have tried exporting the image as a .png, .jpg, and .bmp. All of these look correct in an image viewing program, such as Windows Photo Viewer and Paint, but when I set the Windows background to these images, curves show pixelation and straight lines are jagged. Reading online, it seems that behind the scenes, Windows is converting the image to a .jpg with low quality compression, which is causing the issue. I've tried setting the image as a background through Internet Explorer, saving it as a .jpg, and putting the file in the Windows photo directory as suggested in some online forums, but none of those solutions have fixed my issue.

• Installing SSL certs with nginx on Amazon EC2

  - by Ethan

  I finally got a cert from an authority and am struggling to get things working. I've created the appropriate combined certificate (personal + intermediate + root) and nginx is pointing to it. I got an elastic IP and connected it to my EC2 instance. My DNS records point to that IP. But when I point the browser to the hostname, I get the standard "Connection Untrusted" bit, with ssl_error_bad_cert_domain. Port 443 is open - I can get to the site over https if I ignore the warning. Weird thing is, under technical details, it lists the domain I tried to access as valid! When I try and diagnose with ssl testing sites, they don't even detect a certificate! What am I missing here? domain is yanlj.coinculture.info. Note I've got coinculture.info running on a home server without a dedicated IP and have the same problem, but I'll be moving that to the same EC2 instance as soon as I figure this thing out. I thought the elastic IP would solve things but it hasn't

• How to edit and enlarge the font in a PDF document? [closed]

  - by Gus

  Possible Duplicate: How to enlarge a PDF document on Kindle? I have a kindle 6". The problem is that I often read pdf files that are technical, therefore, it doesn't get converted very well to Kindle's native format (for example, code blocks get messed, and things like that). When I watch the pdf page, it's very small to read easily, so I have to rotate the screen to a horizontal position in order to see it better, but my page get divided. But some documents would be easy to read in vertical position if I had the chance to enlarge the font size a little bit in a external pdf editor, therefore enabling the reading in the vertical orientation. Is there a way to change the font size in a pdf file?

• Home Server restore fails cannot find boot device

  - by Tim Heuer

  I am using Windows Home Server to backup my PCs. I recently had a hard drive failure on one of my WHS connected PCs and obtained an identical sized/speed drive for my laptop. I used the latest home server restore CD and did the restore. It said it completed successfully. Upon reboot, it says 'cannot find boot device' and lists all my drives (hard drive, cd, network book) indicating no valid operating system was found. I boot using the Win7 repair disk and while it doesn't see the operating system, it sees the drive and if I go into a command prompt, I can see all my data on the drive. My laptop is Windows 7 64-bit Ultimate. I've tried most everything I can think of. I'm a technical user (software developer) so I'm pretty aware of how things work (or should). I don't feel like I'm missing a simple step here.

• I have a dead laptop, what are my options?

  - by Michael Kniskern

  After having my previous question answered by the HP technical support, I now have a HP laptop that does not work properly. HP recommended that I replace the motherboard and processor for a bargain price of $733 US dollars. I originally purchased this laptop back when the Windows Vista was released back in January 2007 for about $2,000 US dollar, but now is an very expensive paperweight. What are my options for this laptop? Do I try to revive it on my own.... What are your suggestions?

• More than one XP Mode virtual machines okay under Win 7?

  - by kousen

  I really like the Windows XP Mode virtual machine that comes with Windows 7 (once you download the integration components). I teach technical training classes, and having a machine configured for the classroom is very helpful. My question is, can I configure more than one? The documentation suggests you can make multiple virtual machines, but I can't tell if I can have multiple "Windows XP Mode" VMs. It can't be as simple as configuring one, then just making a copy of the primary disk file, could it? I only plan to run one at a time, but I'd like to configure multiple different VMs for different classes, all running XP if possible. Thanks for any help!

• How does one delete a directory filled with files and other subdirectory permanently, bypassing the trash, from the command line in OS X?

  - by Jon

  So my command line skills are a little rusty and I'm having trouble remembering the differences between the meanings of flags in different distro's os's. I also don't really remember all my technical lingo so manpages seem really unclear. Basically I'm on Mac OS X and want to delete a directory along with all of its contents. What I'm mainly concerned about, I suppose, is that it'll delete literally ALL of the references within the directory, including ../ and ../<everything else, including ../'s own ../> and then just totally screw up my entire system. Which of these do I want to run? $ rm -R dir-name/ or $ rm -r

• What is the best free service to host images and mp3 files?

  - by Edward Tanguay

  I am making an educational social software silverlight application. I would like users to be able to point the application to a URL with text, images, and audio files which they have created. Many users will not have their own website to do this, so we are looking for a free service they can use to upload, and manage their own text/image/audio content. What is the best free service for non-technical users to upload and make available text, images and audio? For instance, sites.google.com allows you to upload pictures and access them via http so that would work, but that is more about making a website. For this purpose we just need the ability to upload files, without the website creation tools.

• Intermediate SSL Certificates on Azure Websites

  - by amhed

  I have successfully configured an Extended-Validation Certificate on an Azure Website following this article: http://www.windowsazure.com/en-us/documentation/articles/web-sites-configure-ssl-certificate/ The main (non-technical) stakeholder of the web application went through great lengths to validate that our site is secure. He went to this site to check the validity of our SSL: http://www.whynopadlock.com/ The site throw the following error: `SSL verification issue (Possibly mis-matched URL or bad intermediate cert.). Details: ERROR: no certificate subject alternative name matches`` The certificate is installed using IP Based SSL instead of SNI. This is done this way because some site visitors still use Internet Explorer 8 on Windows XP, which has no support for SNI and throws a security warning. Is my certificate correclty installed? I received three .CRT files from my SSL provider: PrimaryIntermediate.crt SecondaryIntermediate.crt EndCertificate.crt This is how I exported our certificate as a .PFX file to Azure: openssl pkcs12 -export -out myserver.pfx -inkey myserver.key -in myserver.crt

• Ubuntu on an XPS 14 Ultrabook with mSATA cache and 500GB HD - how to partition for dual boot?

  - by JDS

  I am getting an XPS 14 ( http://www.dell.com/us/p/xps-14-l421x/pd ) and I want to dual-boot Windows and Ubuntu. This thing has a 500GB standard HD and a 32GB mSATA that can be used as cache. Does anyone know how this thing is partitioned? Is the OS installed on the mSATA drive and data is on the big HD? Is there a BIOS controller or maybe even a Windows driver that makes the mSATA drive and 500GB HD appear contiguous? I get the impression that something makes the mSATA be used invisibly as cache, but I can't find any technical documentation how that works. My primary concern here is wrt dual-booting Ubuntu. I want to know if I need to partition the mSATA separately, or the big HD, or just partition the "magic" contiguous disk space that appears available to the OS.

• Book recommendation for learning server management and Apache

  - by japancheese

  Hello, I'm currently managing a site that I feel could be optimized and utilized to be much faster, however, I'm having difficulty finding reliable information to do it. I find the Apache documentation to be a hard read, and too technical about things I don't have a strong grasp on. I'm just looking for a good beginner/intermediate book about server administration to learn as much as possible about Apache, as well as how to create a nice secure, robust server that doesn't crash at the first hint of unusual traffic surges. Thanks to anyone who can point me in the right direction.

• A website hosted on the 1.0.0.0/8 subnet, somewhere on the Internet?

  - by Dave Markle

  Background I'm attempting to demonstrate, using a real-world example, of why someone would not want to configure their internal network on the 1.0.0.0/8 subnet. Obviously it's because this is not designated as private address space. As of 2010, ARIN has apparently allocated 1.0.0.0/8 to APNIC (the Asia-Pacific NIC), who seems to have begun assigning addresses in that subnet, though not in 1.1.0.0/16, 1.0.0.0/16, and others (because these addresses are so polluted by bad network configurations all around the Internet). My Question My question is this: I'd like to find a website that responds on this subnet somewhere and use it as a counter-example, demonstrating to a non-technical user its inaccessibility from an internal network configured on 1.0.0.0/8. Other than writing a program to sniff all ~16 million hosts, looking for a response on port 80, does anyone know of a directory I can use, or even better yet, does anyone know of a site that's configured on this subnet? WHOIS seems to be too general of a search for me at this point...

• How to solve my black screen at boot?

  - by Juanillo

  I've got a friend with a weird problem. When he starts his computer the screen is completely black until the computer is completely started. So the screen is black until it suddenly shows the Windows desktop. He said that this is happening since a technical service repaired his computer, but that repair is not now in warranty. Recently the computer stopped working, but as the screen is black he cannot access to BIOS or start in safe mode (by pressing F8). When he inserts the Windows Vista DVD the system doesn't boot from DVD (it mustn't be configured in this way in the BIOS). Maybe there´s a problem with the hardware (maybe the graphic card)? Can anyone explain a reason why the screen is black during start-up? Any idea of what to do with the computer to restore it?

• Which window manager do you use?

  - by Stephan202

  Combining "What is your default web browser?" and "What are the differences between Linux Window Managers", I ask you: which window manager do you use, and why? Myself I prefer a minimal window manager on the one hand (in the past I used Fluxbox), but on the other hand wish to go with the main stream, to ease finding (Googling) solutions in case of problems. Hence I stick with Gnome as it is shipped with Ubuntu. Why do you use the window manager which you use? I understand some reasons may be subjective, but please try to cite technical reasons where possible.

• How to prove that an email has been sent?

  - by bguiz

  Hi, I have a dispute on my hands in which the other party (landlord's real estate agent) dishonestly claims to not have received an email that I truly did send. My questions is, what are the ways to prove that the email was indeed sent? Thus far, the methods that I have already thought of are: Screenshot of the mail in the outbox Forwarding a copy of the original email I am aware of other things like HTTP/ SMTP headers etc that would exist as well. Are these useful for my purposes, and if so how do I extract these? The email in question was sent using Yahoo webmail ( http://au.mail.yahoo.com/ ). Edit: I am not seeking legal advice here, just technical advice as to how to gather this information.

• Is it possible to combine two internet connections to increase performance?

  - by cornjuliox

  I've got a small home network, 3 PCs plus a laptop or two when the relatives come to visit, connected to a single cable internet connection. Now, as soon as everyone starts using the 'net the performance starts to suffer and if the load is heavy enough nobody can get anything done and everyone complains. At one point it was so bad that only one of us could use it at a time. I was researching possible solutions to this problem and I heard that internet cafes that utilize 2 internet connections, possibly from different providers, and have some sort of router that allows them to split the traffic between the both of them, with online games going through one and web traffic going through another. Is this possible? What is the technical term for it, and can/should it be applied to a home network setup or is there another solution to this problem?

• Update saved password for basic authentication using a script

  - by Kalamane

  I have a website that uses basic authentication as described on this webpage. Each of the computers I manage have the password saved in their browser. There is only one username and password for this. After someone logs in to the site this way, they are presented with their individual username and password prompt as part of the web page. The purpose of the initial username/password is to discourage non-technical employees that aren't supposed to be using the page from even viewing it. So far, when we've had to change this password, I've manually gone to each computer and updated the saved password. I'm writing a startup script to configure other aspects of these systems so that I can maintain them easier. I'd like to be able to update the saved password via this script. The operating system running on these machines is Windows XP SP3 and the browsers they're using to access this site are IE8 and IE9. How can I update the saved basic authentication information for a website via a script?

• linux ftp server with virtual users

  - by kjertil

  i know there are already similar questions for this matter but the answers doesn't really make much sense to anyone who is not really technically comfortable in Linux. I've already tried articles like these for example: http://howto.gumph.org/content/setup-virtual-users-and-directories-in-vsftpd/ with the result of accidently breaking the whole system. The problem is that, while there are several technical possibilities to set up virtual users with a FTP server, it is not as easy as managing for instance a Filezilla server on Windows. I've seen some Web based GUI's but most of them seems to be out of date. The different flavours of Linux and the large amount of different popular FTP servers also seems to make the matter more complicated. I guess my question is, is there a way, to set up virtual FTP users on Linux without the hastle of having to manually edit PAM, MYSQL and config files?

• Good documentation tool that is not Latex?

  - by flpgdt

  I am far from being a expert in Latex but I'm ok to document my projects with it. Though I would seldom find people in the corporate word eager to learn latex and going along with the documentation. 99% of the cases they would just ask me the Word version of it. For technical documentation I find less resistance, but still, whenever I start a project with someone not familiar with latex, the starting up is troublesome. That said, latex is a bit of an oversize tool for my needs really. My documents hardly go further from tables, lists, few images and type styles (although I'd love to still be able to produce hyperlinked PDFs). What are other tools there, simpler and with a easier learning curve than Latex, but still PDF worthy and with minimally decent capabilities? It also has to run on windows :( Oh. yeah, MSWord is not an option ;)

• Restoring files from blueprint on command

  - by Nick

  I am setting up a server. I already have rented a machine running centOS 6 but I have run into a bit of a technical problem with configuring the server software: The server will have some files that it will try to read/write to them but what I need is a way to have a blueprint of these files and everytime the server restarts the files that it used get deleted and replaced by the blueprints. I have heared of a RAM disks or Virtual File Systems but didnt quite understand how they work or how to set them up. The server software is written in java which means bash commands can be run from it. I cannot modify what happens when the server shuts down entirely what I can do is run a command before the server runs the final shutdown save
