• Is it possible to host a website in the 'ether' of the Internet -- not on a server -- so that it can

  - by Christopher Altman

  This is a theoretical problem I am curious about. Websites are hosted on servers. Servers can be taken offline. Is it possible to host a website in the 'ether' of the Internet -- not on a server -- so that it cannot be taken down? One example, is that the website is hosted on other websites, like a parasite. Another is that it is assembled through storing pieces on DNS machines, routers, etc., so that it get assembled on the fly. The purpose is that this website could live forever because no one person can remove it. The answers I am looking for are plausible idea/approaches on technically how this could be built.

• WCF does not generate the properties

  - by BDotA

  I have a .NET 1.1 ASMX and want to use it in a client WinForms app. If i go wit the old way and add it as a "WebRefrence" method then I will have access to two of its properties which are "url" and "UseDefaultCredentials" and it works fine. But if I go with the new WCF way and add it as a ServiceReference I still have access to the methods of that ASMX but those two properties are missing. what is the reason for that? so for example in the old way ( adding WebReference) these codes are valid: TransferService transferService= new TransferService(); transferService.Url = "http://something.asmx"; transferService.Credentials = System.Net.CredentialCache.DefaultCredentials; string[] machines = transferService.GetMachines(); But in the new way ( adding Service Reference ) using(TransferServiceSoapClient transferServiceSoapClient = new TransferServiceSoapClient("TransferServiceSoap")) { transferServiceSoapClient.Url = "someUrl.asmx"; //Cannot resolve URL transferServiceSoapClient.GetMachines(new GetMachinesRequest()); transferServiceSoapClient.Credentials = .... // //Cannot resolve Credentials }

• Click Once doesn't create StartMenu entry and Shortcut on Windows 7 x64

  - by MadBoy

  I've application that I deploy to share with ClickOnce so other users can install it and use it on their own machines. It worked fine till i noticed that when i install this app on my own machine (Windows 7 x 64) it doesn't add StartMenu (even thou it installs correctly and I have it in Control Panel / Programs). I didn't had that problem when my development machine was Windows XP. Application also deploys fine on other Windows XP computers. Also during installation (when i rerun setup) even thou I already have Net Framework 3.5 it always wants to install one (it starts that and terminates few seconds later - probably installer sees that it's already there). I can run application straigit from share just a bit of pain to do it. Are there some special settings I should do? Or some patches? I have Visual Studio 2008 and system with all optional updates installed. Application is written in C# and uses NET 3.5.

• How does one use dynamic recompilation?

  - by acidzombie24

  It came to my attention some emulators and virtual machines use dynamic recompilation. How do they do that? In C i know how to call a function in ram using typecasting (although i never tried) but how does one read opcodes and generate code for it? Does the person need to have premade assembly chunks and copy/batch them together? is the assembly written in C? If so how do you find the length of the code? How do you account for system interrupts?

• Learning resources for Linux filesystem, command line, and structure

  - by webworm

  Can anyone suggest some good materials for learning more about the Linux filesystem and command line? I have found myself frequently confused as to what programs go where on the Linux filesystem. I would like to learn how the various directories (var, etc, usr ...) are used and how to use the commandline more effectively. I come from the Windows development world (.NET developer) so I am very familiar with Windows system administration. However, when doing more and more work with PHP I found myself lost in the internals of Linux (specifically Ubuntu). For example I was having problems installing PEAR properly on my Ubuntu system and not understanding why it was installed where it was. All of my interactions with Linux machines is done via SSH so I would like to focus on the command line and the filesystem. Thanks for any suggestions.

• How can I script the deployment of a Visual Studio database project?

  - by Matt

  How can I script the deployment of a Visual Studio database project? I have a DB project in visual studio and I would like to use it in order to deploy on remote machines via a script. I notice that when I 'deploy' from visual studio, it generates a .sql file. I intercepted this file and tried running it from the command line with osql.exe, but I didn't have any success. Should this work, is there a better way to deploy a database programatically from a database project, may be by referencing in another project and calling some method to deploy it?

• Datetimepicker in windows 7

  - by maramasamy

  I am using Microsoft Date and Time Picker control(SP4) in my application.My application runs fine in xp and vista machines as date and time picker refers to mscomct2.ocx which is present in system32 for xp and vista,but for windows 7 i dont have this dll in my system .In windows we need admin rights to register that control. So is there any alternative/similar control available.......It would be helpful if you could let me know why thats not available in windows P.S : My Application is a .Net application and the reason why i have used Microsoft Date and Time Picker control(SP4) instead of .Net provided control is to display year 9999.

• Using java to send/receive different objects through UDP

  - by AAA

  Hello everyone, I am writing a program in Java where there are communications between two or more machines using UDP. My application sends objects after serializing them through the network to the other machine where it will be deserialized and dealt with it. I was successful in sending one kind of objects so far. My problem is that I want the sender to be able to send different kind of objects, and for the receiver to be able to receive them and cast them again to their appropriate types. However, since UDP allocates a byte buffer then receive the data into the buffer, it is impossible to cast or detect the type of the received object as different objects have different sizes. Is there is a way that I can use to send different kind of objects using UDP and then receive them at the other end? (I don't ask for code here, just some ideas) Thanks

• Is man-in-the-middle attack a security threat during SSH authentication using keys?

  - by JP19

  Hi, I am no expert in network security, so pardon if this question is not very smart :). I am automating logins to some machines using ssh. I am currently avoiding host-key warnings using StrictHostKeyChecking no. I naively understand that someone can impersonate as the server and I risk losing my password to him if that were the case. However, if I am using only public/private Key based authentication ( using PasswordAuthentication no ), can the intruder still cause harm? So basically, with ssh -o "StrictHostKeyChecking no" -o "PasswordAuthentication no" : 1) Can the intruder decipher my private key? 2) Are there any other security threats? regards, JP

• Messy bash variable

  - by Kyle

  I'm writing a script to ssh in to a list of machines and compare a variable to another value.. I've run into a problem (I have a couple workarounds, but at this point I'm just wondering why this method isn't working). VAR=ssh $i "awk -F: '/^bar/ {print \$2}' /local/foo.txt" ($i would be a hostname. The hosts are trusted, no password prompt is given) Example of foo.txt: foo:123456:abcdef bar:789012:ghijkl baz:345678:mnopqr I'm assuming it's a problem with quotes, or \'s needed somewhere. I've tried several methods (different quoting, using $() instead of ``, etc) but can't seem to get it right. My script is working correctly using the following: VAR=ssh $i "grep bar /local/foo.txt" | awk -F: '{print \$2}' Like I said, just a curiousity, any response is appreciated.

• Web Setup Project - Getting the Current Machine Name

  - by Shane Kenney

  I've got a web setup project with a custom screen in it that asks for a machine name. Is there anyway to prepopulate this field with the current machines name? For the case that I need it for just including "Localhost" does not meet my requirements. "Environment.MachineName" will return the machine name within a code block which would be fine if I was needing it in a custom action. But it seems custom actions don't excecute until after you go through the installation wizard... So I cant actually use it. Anyway let me know what you think.

• How to find out who's causing an access violation error?

  - by Fernando

  I'm getting reports that my app is causing a GPF on some Vista machines. The error message is something like this: access violation at 0x75784062 ( tried to write to 0x00000006) In order to fix this, I first need to know exactly who is causing this GPF: my main exe, some third party component, one of my own activex components, a dll, etc... How can I find this out? What tools can pinpoint the exact module that caused this mess? Any help would be greatly appreciated. PS My app is coded in VB6 and my activex controls are written in Delphi 2007.

• Setting up a web developer lab for learning purposes

  - by Saleh Al-Abbas

  I'm not a developer by profession. Therefore, I'm not exposed to real world technical problems that face professional developers. I read/heard about web farms, integration between different systems, load balancing ... etc. Therefore, I was wondering if there are ways for the individual developer to create an environment that simulates real world situations with minimal number of machines like: web farms & caching simulating many users accessing your website (Pressure tests?) Performance load balancing anything you think I should consider. By the way, I have a server machine and 1 PC. and I don't mind investing in tools and software. PS. I'm using Microsoft technologies for development but I hope this is not a limiting factor. Thanks

• .NET Process.Start() on an executable on a remote system - security warning?

  - by BrettRobi

  I've created a Windows Service that accepts commands from remote machines via WCF. One of those commands is to run a specified executable (let's ignore the security implications of such functionality). In my Service I am using Process.Start() to run the executable. All works well if the executable is local to the machine, but if it is on a remote file share it is failing with no error (or more accurately just hanging). I suspect the problem is that it is triggering the standard Windows 'Unverified Publisher' warning that one would see if they double click an exe on a remote system. Is there any way I can bypass this from my service so that I can truly run any executable? As I said I understand the security implications of allowing it to run any executable, but this is really what I need. I would have thought this warning was only a user mode concept, but it really does seem to be getting in the way of my Service. Ideas?

• Using installshield to replace a same-versioned DLL in the GAC

  - by Kevin

  We recently put out an update of one of our apps with a "test" DLL from a third party. The third party does not update their assembly versions on the dll's, only the file versions, so multiple apps can reference different "versions" of it. However, the GAC still allows us to keep the newest version, because it also checks the file version which is always updated. What happened is we were not ready to release this DLL, but it got out there on some customer machines. I would like to put our current live version back out there, but it has an older file version (and the same assembly version) as the test DLL. We have multiple apps referencing this DLL, so I can't simply delete it and drop in the new one. Is there a way to replace the DLL in the GAC? I'm using installshield 2009. Perhaps some sort of custom action upon install?

• Testing perceived performance

  - by Josh Kelley

  I recently got a shiny new development workstation. The only disadvantage of this is that the desktop apps I'm developing now run very, very fast, and so I fear that parts of the code that would be annoyingly slow on end users' machines will go unnoticed during my testing. Is there a good way to slow down an application for testing? I've tried searching around, but all of the results I've been able to find seem pretty fiddly to set up (e.g., manually setting up a high-priority CPU-bound task on the same CPU core as the target app, or running a background process that rapidly interrupts and resumes the target app), and I don't know if the end result is actually a good representation of running on a slower computer (with its slower CPU, slower RAM, slower disk I/O...). I don't think that this is a job for a profiler; I'm interested in the user's perception of end-to-end performance rather than in where the time goes for particular operations.

• How can I build against Microsoft.Web.Administration (IIS 7.x) on a Windows 2003 build machine?

  - by JohnL

  Hi, I am writing a C# config app for (amongst other things) setting up websites. It's only required to support IIS 7.x (Windows 2008 / 2008 R2), and requiring the compatibility pack is a no-no, so I figured I'd just use the Microsoft.Web.Administration namespace. However, the only place I can find the assembly that contains this namespace (Microsoft.Web.Administration.dll) is from the IIS 7.x installation folder, and our main build machines are Windows 2003 and so cannot install IIS 7.x. One option is to mandate a 2008 build machine but we currently only have one so that's not ideal. We've already ruled out appcmd.exe. The other option is to make a package consisting of the dlls necessary to build against Microsoft.Web.Administration.dll. Has anyone tried that? Is there such a package already in existence, hidden somewhere on the MS download site? Thanks in advance.

• Can I allow a write access to a particular registry key without elevation?

  - by 280Z28

  I develop an extension for Visual Studio 2005, 2008, and 2010. The Visual Studio 2005 SDK requires write access to the following registry key during builds. The normal way to handle this run Visual Studio with elevated privileges. The entire issue can be avoided if there's some way I can set permissions to allow access to this particular registry key without elevation: HKLM\SOFTWARE\Microsoft\VisualStudio\8.0Exp Side note: This key is only used for testing Visual Studio 2005 extensions. The issue does not occur on client machines so this is just a workaround for my own development machine.

• Can a 32-bit RHEL4 userland work with a 64-bit kernel?

  - by James

  Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries? On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy: http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r. What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.) Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.

• Compiling flex file into dll.

  - by Szpilona

  Hi, I've got a lexer created with flex (cygwin). Normally I compile it to an .exe file. For the newest project I need a lexer to use in a bigger C# program running on Windows XP. Of course I can execute a file using System.Diagnostics.Process. But it is not the best solution for me as I want that program to run on several machines. How can I create a dll under cygwin having the source code of the lexer? Thanks in advance... Szpilona

• ADO Error: Automation error - The specified module could not be found

  My VB6 application which runs successfully on many machines is producing the above error on just 1 users machine. Machine has Vista SP1 which means the MDAC installer will not work since MDAC 2.8 is already included.

• Mac OS date command - getting higher resolution time

  - by Mark

  Hey all, I am trying to use the date command in Terminal on multiple Mac OS X machines that are synced via NTP to synchronize some code in a program. Essentially I am running a program... MyProgram with arguments[date] I can get date to give me the seconds since the Unix epoch with the %M specifier. When I try to use %N to get nanosecond resolution, date just returns N. Is there anyway to get date to give me finer then second resolution? I wouldn't even mind passing two arguments such as (date +%M):arg2 And then converting units in the program. Many thanks in advance! %N specifier listed here: http://en.wikipedia.org/wiki/Date_(Unix)

• If I specify a System property multiple times when invoking JVM which value is used?

  - by RobV

  If I specify a system property multiple times when invoking the JVM which value will I actually get when I retrieve the property? e.g. java -Dprop=A -Dprop=B -jar my.jar What will be the result when I call System.getProperty("prop");? The Java documentation on this does not really tell me anything useful on this front. In my non-scientific testing on a couple of machines running different JVMs it seems like the last value is the one returned (which is actually the behavior I need) but I wondered if this behavior is actually defined officially anywhere or can it vary between JVMs?
