• Hyper-V and host-installed hardware devices: can guest VMs access?

  - by gravyface

  Have a couple of servers I'd like to setup as Hyper-V Servers, with a couple of Windows 2008 Standard VMs. On the host, we have a few hardware devices we'd like to be accessible to the guest; I'm not sure if these are supported via a raw "pass-thru" on Hyper-V (which I don't have a lot of experience with) if the same drivers are installed on the guest. Hardware in question is a Brooktrout fax card, a SCSI adapter for the tape drive, and a 9-pin serial connected to one of the core firewalls for management.

• How can I combine 30,000 images into a timelapse movie?

  - by Swift

  I have taken 30,000 still images that I want to combine into a timelapse movie. I have tried QuickTime Pro, TimeLapse 3, and Windows Movie Maker, but with such a huge amount of images, each of the programs fail (I tried SUPER ©, but couldn't get it to work either...?). It seems that all of these programs crash after a few thousand pictures. The images I have are all in .JPG format, at a resolution of 1280x800, and I'm looking for a program that can put these images into a timelapse movie in some kind of lossless format (raw/uncompressed AVI would be fine) for further editing. Does anyone have any ideas, or has anyone tried anything like this with a similar number of pictures?

• How to recover the data from the crashed (external) hard disk drive (NTFS)?

  - by shveerab

  The 300 GB harddisk has 2 partitions,90 GB and 200 GB! I can see the drives in windows(XP) but unable to access them, the file system is shown as RAW, 0 used space and 0 free space!..chkdsk returns the error "unable to determine volume version and date. chkddsk aborted." Is the MBR corrupt? How do I restore it? TestDisk tool isn't recognizing the partitions and says invalid entry for heads/cylinder, 15 and should be 255 and suggests to change it..Should I go ahead and change it? Please advise!

• How can I make a non-destructive copy of a (NTFS) partition?

  - by violet313

  I want to recover some deleted files from a healthy NTFS partition on an undamaged hard-disk. In order to leave the partition undisturbed, i plan to use dd to clone the partition to a raw image file & then attempt recovery from that mounted clone. Will dd if=/dev/sd<xn> of=/path/to/output.img perform a non-destructive copy ? Is attempting a restore from a clone using dd the best approach? [edit, wrt Deltiks answer, i need to be a bit clearer about what i'm asking] eg: are there some s/w that can do something more with the original sectors ? eg: if it was a damaged hard-disk i am aware that any kind of read is potentially destructive. but assuming my disk head is not going to suddenly spaz out etc, am i reducing my chances of a successful recovery (at any cost) by using an apparently non-destructive single read of my undamaged hard-disk. (btw: i am planning on using ntfsundelete & testdisk for recovery)

• Is there Linux Live USB that works with Snow Leopard macbook pro from 2010 april

  - by rofrol

  Hello, I was searching for a long time a Linux Live USB that I can boot my macbook pro from. Is there such distro so I can install it on Snow Leopard or Windows 7? UPDATE I've found this: "isohybrid" CD images (..) are special in that as well as the normal CD-based ISO9660 filesystem they also contain a valid-looking DOS-style partition table. Thus, if you simply copy one of these images raw to a USB stick a normal PC BIOS will boot the image directly. (...) Finally: I'd like to add support into xorriso for creating the nasty HFS hybrid images that are needed for booting Macs. The code that does this in cdrkit is probably some of the worst that I've ever worked with, and I'd like to get away from it. If only Apple hadn't stupidly built their proprietary platform around this shit and had used open standards instead Source

• Viewing zip archive contents using 'less' on OS X.

  - by multihead

  I couldn't help but notice that the 'less' program on all of the recent distributions of Linux that I've used (Ubuntu and Gentoo in this case) allow me to view the contents of ZIP and TAR archives, while the install of 'less' that I have on OS X (and Solaris) instead produce a "foo.zip may be a binary file. See it anyway?", which proceeds to spit out the raw binary data instead of a nice file structure listing. Google has not produced much in the way of helpful results -- it's tricky to search for 'less' in this context. I downloaded and built the latest version from greenwoodsoftware.com, but even it refuses to show the contents of these archives. I didn't come across any related configure/build options either. Any ideas? Thanks!

• How do I completely turn off Excel 2010 autoformatting?

  - by Samuel

  I am using a lot of csv files at work with excel 2010. These have no formatting so Excel 2010 autoformats all the cells. I've found workarounds but the ones I have found require action for each file or each cell (i.e. adding a single quote). My current workaround is using the "show formulas" option under formula auditing in the formulas tab. This seems to show the raw data (since they are just csv files there aren't formulas). If I could just keep this active so I don't have to turn it on.

• How to fix a folder content glitch in a FAT32 filesystem?

  - by kagali-san

  at my 450gb fat32 partition, a directory has a wrong content after improper usb drive disconnect; was: /files (total 250gb) /files/folder/ /files/folder2/ /files/somethn.gs Now: /files/weir?d?name, 5 mb Windows and Linux are saying that most (400 of 450gb) disk space is occupied, but sum of all files/dirs is about 130gb, so it seems that files are still there?. No write attempts since discovery; Rejected tools/methods: chkdsk(Windows7): checking completed, but no changes. fsck.vfat: attempted to ruin drive even more (there is a lot of LFN and unicode names). EasyRecovery. Didn't see the target folder (maybe wrong scan options? tried best match, but not raw scan - it would take days since the drive is usb 5200 rpm..).

• FreeBSD Jail own network stack with vimage

  I want to throw all services from the host system and put them in jails. Unfortunatly this doesn't work for file sharing (e.g. nfsd) because the jails don't have there own network stack by default. I know read something about vimage which would solve this issue. See more in this thread: http://forums.freebsd.org/showthread.php?t=9006 The use of vimage with raw jails should use moreorless but the use with vimage and ezjail makes it hard. Does anyone have experience about this topic and wants to share it? Regards

• Linux command line based spam checker?

  - by anonymous-one

  Does a command line based spam checker exist? We have created a mailbox at a 3rd party, and unfortunately decided on spam checking 'disabled' in the initial setup. There is no way to re-enable spam checking, the mailbox must be delete (and thus all contents lost) and re-created. Does anything exist where we can pump in either: A) Subject + from + to + body + all other fields. OR B) Raw message dump (headers + body). And the command line will let us know weather the email is possibly spam? Thanks.

• linux - Is Debian "lighter" than Ubuntu?

  - by user2983756

  I currently run Linux Mint 14 KDE on a "semi-old" machine I use for working and surfing the web - it was the first Linux system I ever used (running away from old Win XP), so I picked a complete system that would have most of my basic needs installed (I didn't even know what exactly all those needs were at the time). The thing is, my computer is becoming really old and Mint is a cluttered system, and for the next installation I'm going to try and install a "raw" system and get everything from the online repos. My question is: Since Ubuntu is Debian-based, does that make it consume more resources than its base system? If that isn't the difference, which one is "lighter" in that sense?

• How to fix a Corrupted USB

  - by Help

  My USB stick has suddenly stopped working. It's a Busbi 4GB. My USB used to be G:/ but as soon as I plugged it in, I used to get a pop up box showing that it was plugged in. Now, when I plug this in, it shows as I:/ and no pop up box appears. It shows in my computer as I:/ and when I click to open it says I:/ is not accessible the disk structure is corrupted and unreadable. I have tried to change the file name back to G:/ but nothing happened (this was under disk management). On disk management, it shows Volume as I:/ Layout simple Type Basic File system RAW status Healthy (Active,Primary partition) Capacity 3.42GB. I've tried right clicking properties then the tab tools and click error checking (this option will check the volume for errors). When I click "check now" it comes up with the disk check could not be performed because Windows cannot access the disk.

• Silverlight Ftp Upload

  - by Curtis

  Hi I'm working on trying to ftp a file to the server through a silverlight application. Where the location to upload the file on server file system, exists outside the sandbox area for the web server. In this case the web server root exists at "C:\test\www\" and the location to upload the file will exist at "C:\User\Uploads". In this scenerio i'm not sure if Http POST will work (doesn't that use the web server root). I just need to upload the file selected by the user to a different location that may exist outside the sandbox. With silverlight i'm thinking sockets are my last option based on the limited port range for silverlight being 4502-4532. Can i do this using WebClient and Http POST? Can i make an ftp connection through silverlight or javascript?

• HttpWebRequest and BindIPEndPointDelegate getting socket exception

  - by Evgeny Gavrin

  I've got c# code running on a computer with multiple network interfaces, and the following code to select an IP address for a HttpWebRequest to bind ServicePoint: HttpWebRequest request = (HttpWebRequest)WebRequest.Create(remoteFilename); request.KeepAlive = false; request.ServicePoint.BindIPEndPointDelegate = delegate( ServicePoint servicePoint, IPEndPoint remoteEndPoint, int retryCount) { return new IPEndPoint(IPAddress.Parse(ipAddr), 0); }; But it works only for one of the available network interfaces. Trying to access remote server through others throws an exception: System.Net.WebException: Unable to connect to the remote server --- System.Net.Sockets.SocketException: A socket operation was attempted to an unreachable network How can it be solved?

• Convert IP address string to binary in Python

  - by pizzim13

  As part of a larger application, I am trying to convert an IP address to binary. Purpose being to later calculate the broadcast address for Wake on LAN traffic. I am assuming that there is a much more efficient way to do this then the way I am thinking. Which is breaking up the IP address by octet, adding 0's to the beginning of each octet where necessary, converting each octet to binary, then combining the results. Should I be looking at netaddr, sockets, or something completely different? Example: From 192.168.1.1 to 11000000.10101000.00000001.00000001

• socat usage for FIFO speed vs socket speed on localhost

  - by Fishy

  Hello, As per a suggestion on stackoverflow, to compare IPC on a single machine using a) sockets (TCP) on localhost to localhost b) using FIFOs (between Java and C) To answer (a), I used netcat to gauge transfer speed (91 MBytes/sec)[1] (b) Q: How can I test FIFO write speed using socat? My approach(where /tmp/gus is created using mkfifo on RHEL): dd if=/dev/zero of=/tmp/gus bs=1G count=1 but i get: 1073741824 bytes (1.1 GB) copied, 1.1326 seconds, 948 MB/s Does this mean writing to a FIFO ~10 times faster? Or is my experiment completely wrong ? Thank you Sporsi [1] From machine A to B across 1Gbps link, this number dropped to ~80 MBytes/sec - I expected localhost to be much higher ...

• Tiny, very-basic outgoing MTA?

  - by Xeoncross

  I am looking for a very tiny Mail-Transfer-Agent (MTA) for my smaller VPS which only need to send emails for new accounts or notifications. Originally, I used PHP sockets and wrote a 4kb STMP class to connect to google SMTP and send the emails - but I would like to be free of the 500 emails a day (or whatever) limit they have. On larger VPS I can run Postfix - but it takes about 50MB which makes it too big for a 128/256MB VPS. So are there any very tiny MTA's out there - or is there a rundown of the protocol of sending email (I guess it works by forwarding the mail through other servers till it reaches the correct end mail server right?) so I could build a smaller bash or PHP script for this outgoing stuff?

• SLES 9 vs. SLES 10

  - by Michael Covelli

  Are there any important change in how SLES 10 implements Tcp sockets vs. SLES 9? I have several apps written in C# (.NET 3.5) that run on Windows XP and Windows Server 2003. They've been running fine for over a year, getting market data from a SLES 9 machine using a socket connection. The machine was upgraded today to SLES 10 and its causing some strange behavior. The socket normally returns a few hundred or thousand bytes every second. But occasionally, I stop receiving data. Ten or more seconds will go by with no data and then Receive returns with a 10k+ bytes. And some buffer is causing data loss because the bytes I receive on the socket no longer make a correct packet. The only thing changed was the SLES 9 to 10 upgrade. And rolling back fixes this immediately. Any ideas?

• Java: Read POST data from a socket on an HTTP server

  - by danpalmer

  I have a website (python/django) that needs to use a load of Java resources that may or may not be on the same server. Therefore I am writing a mini webserver in Java that will receive a request and then when processing is finished, POST some data back to a url on the site. I have got the java code receiving connections on sockets and responding with some simple HTML. My problem is that I will POST data to the Java server and that code needs to act on the data. How do I go about reading the data that is posted in the HTML request, if it is even possible. If not, is there any other way you would do this. If you think I am going about this in completely the wrong way then please tell me and I will consider another method, but after conversing with some Java developers, this seemed like the best way for what I was doing. Thanks

• [python] voice communication for python help!

  - by Eric

  Hello! I'm currently trying to write a voicechat program in python. All tips/trick is welcome to do this. So far I found pyAudio to be a wrapper of PortAudio. So I played around with that and got an input stream from my microphone to be played back to my speakers. Only RAW of course. But I can't send RAW-data over the netowrk (due the size duh), so I'm looking for a way to encode it. And I searched around the 'net and stumbled over this speex-wrapper for python. It seems to good to be true, and believe me, it was. You see in pyAudio you can set the size of the chunks you want to take from your input audiobuffer, and in that sample code on the link, it's set to 320. Then when it's encoded, its like ~40 bytes of data per chunk, which is fairly acceptable I guess. And now for the problem. I start a sample program which just takes the input stream, encodes the chunks, decodes them and play them (not sending over the network due testing). If I just let my computer idle and run this program it works great, but as soon as I do something, i.e start Firefox or something, the audio input buffer gets all clogged up! It just grows and then it all crashes and gives me an overflow error on the buffer.. OK, so why am I just taking 320 bytes of the stream? I could just take like 1024 bytes or something and that will easy the pressure on the buffer. BUT. If I give speex 1024 bytes of data to encode/decode, it either crashes and says that thats too big for its buffer. OR it encodes/decodes it, but the sound is very noisy and "choppy" as if it only encoded a tiny bit of that 1024 chunk and the rest is static noise. So the sound sounds like a helicopter, lol. I did some research and it seems that speex only can convert 320 bytes of data at time, and well, 640 for wide-band. But that's the standard? How can I fix this problem? How should I construct my program to work with speex? I could use a middle-buffer tho that takes all available data to read from the buffer, then chunk this up in 320 bits and encode/decode them. But this takes a bit longer time and seems like a very bad solution of the problem.. Because as far as I know, there's no other encoder for python that encodes the audio so it can be sent over the network in acceptable small packages, or? I've been googling for three days now. Also there is this pyMedia library, I don't know if its good to convert to mp3/ogg for this kind of software. Thank in in advance for reading this, hope anyone can help me! (:

• Are there some general Network programming best practices?

  - by uriDium

  I am implementing some networking stuff in our project. It has been decided that the communication is very important and we want to do it synchronously. So the client sends something the server acknowledges. Are there some general best practices for the interaction between the client and the server. For instance if there isn't an answer from the server should the client automatically retry? Should there be a timeout period before it retries? What happens if the acknowledgement fails? At what point do we break the connection and reconnect? Is there some material? I have done searches but nothing is really coming up. I am looking for best practices in general. I am implementing this in c# (probably with sockets) so if there is anything .Net specific then please let me know too.

• What technical skills needed for algorithmic trading, HFT, etc?

  - by alchemical

  I'm interested in getting into developing trading systems, black box, HFT, etc. My primary experience is with C# and .Net (7 years). I've also done some sockets programming. I have some experience in finance working on analysis applications (2 years). My goal is to move into developing automated trading systems for a hedge fund, bank, etc. Is there any way to learn the skills needed for this without somehow getting the job first? I've looked at the open source tradelink, IB interactive brokerage, etc. I'm playing around with this framework, and may hook it up and do some paper trading. However, I'm not sure if this has much relationship with how a well-funded entity would be conducting a high-level automated trading operation. I.e. would the tools and frameworks they prefer be a totally different skill-set? Also wondering if I need to learn C++ and/or Java for these types of apps.
