• Where should my application setup put the binary executables in Windows 7?

  - by KeyboardMonkey

  I created a small Windows app, and am builder a setup for it using NSIS, but what I can't find out is where to put the executables to conform to the new Windows security model. Traditionally we put program files in, well, "c:\program files". With the security model getting more mangled with each Windows version, some users have restricted accounts, and I'm not sure installing into program files will work for these users. Where can I install my program's files that will cater for these lower-privileged users? Oh and I want to avoid ClickOnce.

• Can a USB/IDE/SATA adapter be flaky?

  - by Ward

  I use USB/IDE/SATA converters a lot and on the two that I have now, I sometimes get errors copying files to drives. It only happens when I'm copying big files to the drive (big can mean as little as 100MB, I think it happens more often with bigger files - 300MB or more), and basically the copy will fail and I'll get one or more error messages about "Delayed write failed." But if I disconnect the drive and re-connect it, I'll usually be able to continue. (The file that was being copied will be corrupt, but otherwise the drive is fine.) I just noticed a new type of flakiness: the data transfer rate can vary widely. I copied one set of files (5x300MB files) and it took 10+minutes, then I copied another set (approx. the same sizes) and it took less than a minute. I haven't done systematic testing, the other things I'm doing on my laptop at the same time might have some impact, and I haven't cross-checked the two adapters I have and the 3 hard drives I'm working with to see if there's a pattern. I'm more wondering if anyone else has seen anything like this.

• Discrepancy in file size on disk and ls output

  - by smokinguns

  I have a script that checks for gzipped file sizes greater than 1MB and outputs files along with their sizes as a report. This is the code: myReport=`ls -ltrh "$somePath" | egrep '\.gz$' | awk '{print $9,"=>",$5}'` # Count files that exceed 1MB oversizeFiles=`find "$somePath" -maxdepth 1 -size +1M -iname "*.gz" -print0 | xargs -0 ls -lh | wc -l` if [ $oversizeFiles -eq 0 ];then status="PASS" else status="CHECK FAILED. FOUND FILES GREATER THAN 1MB" fi echo -e $status"\n"$myReport The problem is that ls command outputs the files sizes as 1.0MB in the report but the status is "FAIL" as "$oversizeFiles" variable's value is 2. I checked the file sizes on disk and 2 files are 1.1MB. Why this discrepancy? How should I modify the script so that I can generate an accurate report? BTW, I'm on a Mac. Here is what man page for "find" says on my Mac OSX: -size n[ckMGTP] True if the file's size, rounded up, in 512-byte blocks is n. If n is followed by a c,then the primary is true if the file's size is n bytes (characters). Similarly if n is followed by a scale indicator then the file's size is compared to n scaled as: k kilobytes (1024 bytes) M megabytes (1024 kilobytes) G gigabytes (1024 megabytes) T terabytes (1024 gigabytes) P petabytes (1024 terabytes)

• Is there a Distributed SAN/Storage System out there?

  - by Joel Coel

  Like many other places, we ask our users not to save files to their local machines. Instead, we encourage that they be put on a file server so that others (with appropriate permissions) can use them and that the files are backed up properly. The result of this is that most users have large hard drives that are sitting mainly empty. It's 2010 now. Surely there is a system out there that lets you turn that empty space into a virtual SAN or document library? What I envision is a client program that is pushed out to users' PCs that coordinates with a central server. The server looks to users just like a normal file server, but instead of keeping entire file contents it merely keeps a record of where those files can be found among various user PCs. It then coordinates with the right clients to serve up file requests. The client software would be able to respond to such requests directly, as well as be smart enough to cache recent files locally. For redundancy the server could make sure files are copied to multiple PCs, perhaps allowing you to define groups in different locations so that an instance of the entire repository lives in each group to protect against a disaster in one building taking down everything else. Obviously you wouldn't point your database server here, but for simpler things I see several advantages: Files can often be transferred from a nearer machine. Disk space grows automatically as your company does. Should ultimately be cheaper, as you don't need to keep a separate set of disks I can see a few downsides as well: Occasional degradation of user pc performance, if the machine has to serve or accept a large file transfer during a busy period. Writes have to be propogated around the network several times (though I suspect this isn't really much of a problem, as reading happens in most places more than writing) Still need a way to send a complete copy of the data offsite occasionally, and this would make it very hard to do differentials Think of this like a cloud storage system that lives entirely within your corporate LAN and makes use of your existing user equipment. Our old main file server is due for retirement in about 2 years, and I'm looking into replacing it with a small SAN. I'm thinking something like this would be a better fit. As a school, we have a couple computer labs I can leave running that would be perfect for adding a little extra redundancy to the system. Unfortunately, the closest thing I can find is Dienst, and it's just a paper that dates back to 1994. Am I just using the wrong buzzwords in my searches, or does this really not exist? If not, is there a big downside that I'm missing?

• restore -A usage

  - by Martin v. Löwis

  I have created a number of dump files using Linux dump(8), using the -A option to get a table of contents on disk (the backups are on tape). Now I'm trying to look into these archive files, using restore -i -A <archive>` However, this insists on asking what tape to use, and complains if I say none. What am I doing incorrectly? I was hoping that I can use these archive index files without having to insert the tape to use.

• Industrial strength cloud file storage

  - by ArthurG

  I'm looking for an industrial strength cloud file storage system. It will be used by multiple people in a startup. Our requirements: Transparent file system access: files and folders in the file system must be able transparently access (read and write) files in the cloud; files must be synchronized whenever network access is available and buffered otherwise. The system must be usable by non-technical people. Access control: we need to control who can access which files, at least on a very coarse basis. e.g., the developers will be able to access the system design documents, only the corporate folks can access recruiting documents, and only management can access certain corporate documents. Dropbox provides this via Sharing folders, but that's not adequate, if I understand it correctly, because there's no authentication of the sharing user. so the cloud service should have a notion of an account (our startup) with multiple users with distinct credentials and rights for each user Clients: it must be accessible from Macs and PCs; I would hope that it supports Linux (e.g., Ubuntu) too Security: it must provide robust security Backup: the cloud service must reliably backup the files Versioning: change version history, is a big plus, but not required Not free: we're willing to pay for the service So far, we've reviewed the following, albeit not completely thoroughly: Dropbox: has all except 1) Access control, which is provided via Sharing folders, but that's not adequate, if I understand it correctly, because there's no authentication of the sharing user. and 2) Security, as discussed here http://www.economist.com/blogs/babbage/2011/05/internet_security and here http://blog.dropbox.com/?p=821. Windows Live Mesh, has all except 1) Clients, only supporting Windows 7 and OS X. SpiderOak has all, except 1) Transparent file system access, which is only available for 1 user. Amazon Cloud, doesn't offer 1) Transparent file system access Rackspace Cloud Drive has all except 1) Access control and 2) Versioning I'll gladly include any clarifications or additional systems the community provides.

• Windows disk change monitoring for malware analysis

  - by SuperDuck

  Not sure if this question belongs to here, because it has some relations with 'serverfault' (system backups) and 'stackoverflow' (software analysis). I'm looking for a solution to monitor disk changes on a Windows system and selectively revert them. It should be able to handle live files like registry parts, so may need to be an offline backup software. It shouldn't silently pass over files which the current admin user doesn't have permissions on (files with no permission entries or owned by the 'system' user) Registry change tracking would be a bonus but is not a requirement I use virtual machines for malware analysis, there is even no solution to list file changes in disk snapshot files (delta VMDK). I currently use Ashampoo for monitoring changes. Though it's the best one between similars, it's not a good software and hasn't really evolved in many 'platinum', 'deluxe' versions released in the last 10 years (it even used non-resizable windows until the latest version). The real problem is it misses some disk / registry changes. Perhaps it only compares modification dates and doesn't catch a change if the dates are preserved. So, I think the solution should compare files using hashes, or file sizes at least. There are numerous backup software out there and I'm sure one can handle this, offline or online.

• Is there a peripheral that lets my computer monitor the connectivity of pairs of wires?

  - by raldi

  I've got a bunch of physical switches and circuits that act like switches (they're either connected to ground or they're just an open wire). Is there some sort of thing I can plug into my computer (ideally, via USB) that has a bunch of screw terminals, and I can attach wires to the screws and have the computer keep track of which circuits are closed and which are open? Bonus points if the device also lets the computer open and close switches, too. I don't even know what to google for.

• chroot for unsecure programs execution

  - by attwad

  Hi, I have never set-up a chroot-jailed environment before and I am afraid I need some help to do it well. To explain shortly what this is all about: I have a webserver to which users send python scripts to process various files that are stored on the server (the system is for Research purpose). Everyday a cron job starts the execution of the uploaded scripts via a command of this kind: /usr/bin/python script_file.py All of this is really insecure and I would like to create a jail in which I would copy the necessary files (uploaded scripts, files to process, python binary and dependencies). I already looked at various utilities to create jails but none of them seemed up-to-date or were lacking solid documentation (ie. the links proposed in How can I run an untrusted python script) Could anyone guide me to a viable solution to my problem? like a working example of a script that creates a jail, put some files in it and executes a python script? Thank you very much.

• Does moving a file outside NTFS loose data in alertnate data streams?

  - by jay

  I have a lot of files on machine running Windows Server 2008 which I wanted to move to a Fedora machine. How can I keep the attributes stored in, for example, media files (date taken, rating, length, etc) while transfering it to outside the realm of NTFS's Alternate Data Streams. I'm aware that similar metadata exists in other file systems, but what happens when you move these files? And what's the best way to retain them in other file systems?

• How do I use XQuartz with ssh on OS X?

  - by cwd

  I've downloaded the latest stable version of XQuartz on my Snow Leopard machine, and I'm trying to make an ssh connection with X forwarding but X11 keeps opening. How can I get OS X to use XQuartz? I had X11 installed I downloaded and installed XQuartz X11 is not open / running XQuartz is open and running I try and connect to a remote system using iTerm2: ssh user@remote -X X11 opens. XQuartz is still open, but I doubt it is doing anything. I also tried moving X11 to the trash but then the ssh connection will not complete, even though XQuartz is open. I also get the two warnings which I don't understand how to fix, even after reading the ssh man page. Warning: untrusted X11 forwarding setup failed: xauth key data not generated Warning: No xauth data; using fake authentication data for X11 forwarding.

• Episode by episode DVD Rip to AVI on Windows 7.

  - by ProfKaos

  I'm looking for a Windows tool to rip DVD files to AVI files. VidCode looks cool, but it wants to convert the whole DVD (all files in the VIDEO_TS folder) to one AVI. I would like to pull each episode on the DVD to its own AVI. Is their a way to that with VidCode, or another ripper? My Plan B for VidCode is to manually separate files for each episode into their own VIDEO_TS folders. Is this possible? Is there an easy, lazy way to automate this?

• Remote file copy util (like rsync) but that will take account of data already copied (in this sessio

  - by Rory McCann

  Let's say I have a directory with 2 files, both are identical and quite large (e.g. 2GB ea.) I want to rsync that directory to a remote host. As I understand it (and I could be wrong), rsync calculates checksums of files. Surely if it sees 2 files with the same checksum it can just copy the first file, then do a local copy on the remote host for the 2nd file? That would make it faster, no? On a similar note, doesn't rsync hash all the remote files before copying? If it saw a different file with the same hash as a file that was to transfered, it could do a local copy on the remote host. Does rsync support this sort of thing? Is there some way to turn it on? Is there a tool similar to rsync that will do this sort of 'hash based' local copies?

• Can you specify per program how Internet Explorer handles hyperlinks?

  - by Rapida

  Is there a way to configure Internet Explorer's "Open links from other programs in:" option per program? I'm looking for a way to allow different programs to act differently when clicking hyperlinks. For example, if I click a hyperlink in Microsoft Outlook I'd prefer it to open a new tab in the current window (option 2) but if I click a link out of an instant messenger program I'd prefer it to open in the current tab or window (option 3). Version wise I'm looking for a way to do it with IE 8+.

• VirtualBox error with Ubuntu virtual machine

  - by user2985363

  I am trying to work on a coding project and cannot open my Ubuntu virtual machine with Oracle VM VirtualBox. I took a snapshot yesterday at about 11, and it was working fine. Several times I closed and reopened it. Today when I tried to open it, I kept getting the error below. Failed to open a session for the virtual machine Ubuntu 12.04 32-bit. VM cannot start because the saved state file 'C:\Users\Tyler\VirtualBox VMs\Ubuntu 12.04 32-bit\Snapshots\2014-01-30T19-59-05-976647800Z.sav' is invalid (VERR_FILE_NOT_FOUND). Deleted the saved state prior to starting the VM. I tried deleting the file as it said, but none of the snapshots would open still. The file is still in my recycling bin. What can I do? Also, I took the 1/31 snapshot today before I deleted the previous one.

• Windows XP cannot read DVD burned on Ubuntu

  - by webcrawl

  The story : I have burned a DVD disc on Ubuntu using Brasero. When file burning was complete, I canceled the burning of checksum to DVD. Then I put that DVD on Windows XP (SP3) and copied all the files from DVD to the hard drive (no errors when copying). When that was done I discovered that all copied files are not readable. What is more, all the files on that DVD also shown to be not readable, even though all file names, directories were in their place. What I found out? Windows detect that the disc is in CDFS (CD-ROM File System). Disc is clean as new, have no scratches. All files while opened in Notepad++ look like "NULNULNULNULNUL" in one line. The size of files is normal. Other discs that are recognized as CDFS can be read with no problems. What I tried? Starting CDFS service in Windows registry. Result - a new device in Windows Device Manager (JUBS JGH2ZCT SCSI CdRom Device). Removing my CD/DVD device from Device Manager. Result - Windows restarted the system and reinstalled the driver. So... how to read the DVD, when I have no access to any other PC, any other OS?

• Should I go along with my choice of web hosting company or still search?

  - by Devner

  Hi all, I have been searching for a good website hosting company that can offer me all the services that I need for hosting my PHP & MySQL based website. Now this is a community based website and users will be able to upload pictures, etc. The hosting company that I have in mind, currently lets me do everything... let me use mail(), supports CRON jobs, etc. Of course they are charging about $6/month. Now the only problem with this company is that they have a limit of 50,000 files that can exist within the hosting account at any time. This kind of contradicts their frontpage ad of "UNLIMITED SPACE" on their website. Apart from this, I know of no other reason why I should not go with this hosting company. But my issue is that 50,000 file limit is what I cannot live with, once the users increase in significant number and the files they upload, exceed 50,000 in number. Now since this is a dynamic website and also includes sensitive issues like payments, etc. I am not sure if I should go ahead with this company as I am just starting out and then later switch over to a better hosting company which does not limit me with 50,000 files. If I need to switch over once I host with this company, I will need to take backups of all the files located in my account (jpg, zip, etc.), then upload them to the new host. I am not aware of any tools that can help me in this process. Can you please mention if you know any? I can go ahead with the other companies right now, but their cost is double/triple of the current price and they all sport less features than my current choice. If I pay more, then they are ready to accommodate my higher demands. Unfortunately, the company that I am willing to go with now, does NOT have any other higher/better plans that I can switch to. So that's the really really bad part. So my question(s): Since I am starting out with my website and since the scope of users initially is going to be less/small, should I go ahead with the current choice and then once the demand increases, switch over to a better provider? If yes, how can I transfer my database, especially the jpg files, etc. to the new provider? I don't even know the tools required to backup and restore to another host. (I don't like this idea but still..) Should I go ahead and pay more right now and go with better providers (without knowing if the website is going to do really that well) just for saving myself the trouble of having to take a backup of the 50,000 files and upload to a new host from an old host and just start paying double/triple the price without even knowing if I would receive back the returns as I expected? Backup and Restore in such a bulky numbers is something that I have never done before and hence I am stuck here trying to decide what to do. The price per month is also a considerable factor in my decision. All these web hosting companies say one common thing: It is customers responsibility to backup and restore data and they are not liable for any loss. So no matter what hosting company that I would like to go with, they ask me to take backup via FTP so that I can restore them whenever I want (& it seems to be safer to have the files locally with me). Some are providing tools for backup and some are not and I am not sure how much their backup tools can be trusted considering the disclaimers they have. I have never backed-up and restored 50,000 files from one web host to another, so please, all you experienced people out there, leave your comments and let me know your suggestions so that I can decide. I have spent 2 days fighting with myself trying to decide what to do and finally concluded that this is a double-edged sword and I can't arrive at a satisfactory final decision without involving others suggestions. I believe that someone must be out there who may have had such troublesome decision to make. So all your suggestions to help me make my decision are appreciated. Thank you all.

• Make symlink on Windows of whole tree without modifying the original folder

  - by DarkGhostHunter

  I'm trying to do this: make a symlink of a whole directory "C:/Master", in different folders like "C:\Projects\Alpha\", "C:\Projects\Beta\" an so on. "Master" directory usually changes in files and data. I work on the "Projects/*", where every project folder uses the "Master" files, but every one has new files in them. Let's say, I point to the car engine in every project folder, and inside them I add different kind of wheels. The problem I'm having, as a Windows 8 user, is that symlinks (junction) acts as a window to "Master" - I'm not allowed to add any file inside. I looking a way to reference the entire "Master" directory, and add new files - not edit any of the "Master" ones. It's as described here, but on Windows.

• (Win7) Gets stuck with ~1% CPU. Especially with multithreading

  - by meow

  Windows 7 32 bit, up to date, Intel i7 860. (For some reason the company runs 32bit Windows everywhere.) I tried to update all motherboard drivers etc. as far as possible. I have a performance issue with a machine which appears in connection with multithreading (or so I think). As an example (and where I most often see it, but it appears on other programs as well): ProteoWizard is a file conversion tool for mass spectrometry files. I can add a list of files and it will attempt to process up to 8 files in parallel (quadcore x 2 threads/core). If I choose 1 to 6 files, I start the process and it goes straight through. If I have =7 files in the queue, conversion goes to ~20%, then gets stuck for 15 seconds, then continues again, always in "chunks" of a few % before getting stuck again. During the time the process is stuck, CPU is at 1%. RAM is not limiting, it is maybe at 70% or so and not going up. I don't get the same problem on other, even slower machines. The computer gets also stuck at 1% CPU doing nothing on other occasions, but for multithreading it is most frequent. Where should I look for the problem?

• Domain migration - 301 Redirect of all contentes of directory)

  - by Trufa

  Hi, I would like to know if it is possible to do the following considering that I would like to migrate domains. I have lets say: one.com/files/one.html one.com/files/two.php one.com/other/three.html one.com/other/four.doc one.com/other/subdirectory/five.doc I am migrating to two.com So I would like to make RESPECTIVE 301 redirects to the following: two.com/old/files/one.html two.com/old/files/two.php two.com/old/other/three.html two.com/old/other/four.doc two.com/old/other/subdirectory/five.doc I've tried with cPanel and although I come "close" with the redirects option I can't seem to make it happen. The folders are not much (10 -12) the file are a lot, and obviously impossible to make it manually. How would you proceed? Can this/ should this be done with regex from the .htaccess?? Can you direct all the elements of a subdirectory in the manner expressed above? I hope the question is clear enough, if not please ask for any clarification needed!! Thanks in advance!!

• Opening a Corrupted winmail.dat file

  - by tearman

  I have a set of winmail.dat files that apparently have evolved from a set of emails with corrupted headers. It looks like Exchange 2010 changed the headers around sometime last September and basically rendered exported .eml files unable to open. Now the HTML/PlainText emails seem to do ok, but the files that use RichText (specifically Microsoft's TNEF format) will not open in any program, Microsoft or not. I've attempted to use many different non-Microsoft converters and they see it as a corrupted message as well. If I remove the headers of the email, rename it as a winmail.dat file, some emails will open in Word, but most won't. If you take a look at the email in a text editor, there are null characters EVERYWHERE that distort the email itself. Anybody have any experience with this and/or suggestions on how to at least open it?
