• How can I prevent Windows 7 from automatically changing the firewall settings (turning it back on) when changing network location?

  - by YpeDeg

  By default, the firewall is turned on on all my workstations. I want to disable it. That works just fine. However, if Windows thinks there is a change in the Network Location, the "Set Network Location" dialog appears. At that point my Firewall is still disabled. When my users click on any of the three options "Work", "Home" or "Public", Windows immediately changes the firewall settings and turns it back on. Is it possible to stop Windows 7 from automatically turning the firewall back on when you change the Network Location? If yes, how could I perform this task?

• knowing all available entity types

  - by plofplof

  I'm making a game where at some point the game will create enemies of random types. Each type of enemy available is defined on its own class derived from an enemy superclass. To do this, obviously the different types of enemies should be known. This is what I have thought of: Just make a list manually. Very simple to do, but I don't like it because I'll be adding more enemy types over time, so any time I add a new class I have to remember to update this (same if I remove an enemy). I would like some kind of auto-updating list. A completely component based system. There are no different classes for each enemy, but definitions of enemies in some file where all enemy types can be found. I really don't need that level of complexity for my game. I'm still using a component based model to some degree, but each Enemy type gets defined on its own class. Java Annotation processing. Give each enemy subclass an annotation like @EnemyType("whatever"), then code an annotation processor that writes in a file all available enemy types. Any time a new class is added the file gets updated after compilation.This gives me a feeling of failure even if its a good solution, it's very dependant on Java, so it means I cant think of a general design good for any kind of language. Also I think that this would be too much work for something so simple. I would like to see comments on these ideas and other possible solutions Thanks

• How come there is still so much programming work?

  - by jd_505

  I wonder why programming jobs haven't yet "dried up" because of the software evolution, for example, I am a developer myself, which means that I do care about software (I mean I am not of the type of guys that needs a computer mainly to just browse the Internet), and still I wouldn't mind if I never receive any more updates on my Ubuntu machine. I find that it provides everything I need, and while the updates provide various bug fixes/improvements, I wouldn't mind using it with its current state for the rest of my life, for 2 years of Ubuntu usage I have never bumped at a serious bug/problem. Another example is Windows, almost half of it's users still use XP, which is practically ancient, yet they find it satisfying all their needs (and I agree with them). I could go with many more examples, but by now you are understanding my point and my question. While new "trends" appears all of the time (like a new mobile OS) which runs on new platforms and requires some fresh development work, still the majority of the software effort goes in to what I consider as "completed projects", or at least a state of a project which is enough to be considered as completed. Do you have an explanation? I can't think of the right tags for this question; please edit it the way you find it to be most appropriate.

• 1 tera flop cluster?

  - by Adobe

  I want to buy a $40000 1 tera flop cluster to keep it in a room. What are the standard configurations? Cluster is supposed to do molecular dynamics simulations on biological systems. I'm proposed a 4 pc with 8 cores each by the selling company I'm deadling with. It looks like I also need infiniband. Does some one has an experience -- what phisical memory should I buy etc? I know things change very quickly... Still there might be a point or two to state. Edit: Custer is supposed to run linux, and gromacs in it.

• Is it possible to redirect/bounce TCP traffic to an external destination, based on rules?

  - by xfx

  I'm not even sure if this is possible... Also, please forgive my ignorance on the subject. What I'm looking for is for "something" that would allow me to redirect all TCP traffic arriving to host A to host B, but based on some rules. Say host A (the intermediary) receives a request (say a simple HTTP request) from a host with domain X. In that case, it lets it pass through and it's handled by host A itself. Now, let's suppose that host A receives another HTTP request from a host with domain Y, but this time, due to some customizable rules, host A redirects all the traffic to host B, and host B is able to handle it as if came directly from domain Y. And, at this point, both host B and the host with domain Y are able to freely communicate (of course, thought host A). NOTE: All these hosts are on the Internet, not inside a LAN. Please, let me know if the explanation is not clear enough.

• How to enable Integrated Load Balancing in Windows 8

  - by intodevelopment

  One of the cool new features many sites mention is "Integrated Load Balancing" in Windows 8. It is supposed to do the following: If you have multiple active network connections, Windows 8 will intelligently balance the network traffic between them for performance Source: Short: Some of what Microsoft didn’t show of Windows 8 I would love to see this feature in action. I am connected to a WiFi access point and to a different network by cable. Yet I don't see the operating system 'intelligently' balance the network load when for instance downloading multiple files. Is there any way to enable it or should I adjust my expectations?

  I'm trying to deploy a rails app in Debian, using Apache/Passenger. I was trying to fox a problem with some GEMs and in the process I put executed this in console: export PATH=/var/lib/gems/1.8/bin/:${vendor/cache} Now my path environmental variable is gone, or at least its content. My server is running under Debian 6. Is there a way to recover my path info? Or at least can someone point me where to find the file where that variable i s stored? Some help please. This is a BIG problem for me. Thanks in advance!

• SBS 2008 - Blank desktop while installing

  - by Sandokan

  I'm trying to install SBS 2008 Standard Ed on a VMware Workstation 8. The installation runs fine up until some point where the desktop becomes completely blank. The server is still running and responds to CTRL+ALT+DELETE and CTRL+ESC, but there are no icons and no explorer-bar. I have tried to install it twice now and each time it comes to a halt at the same spot. Starting Taskmanager and launching explorer.exe only brings up the filemanager. Anyone have a clue to what it could be?

• Data structure for grid with negative indeces

  - by The Secret Imbecile

  Sorry if this is an insultingly obvious concept, but it's something I haven't done before and I've been unable to find any material discussing the best way to approach it. I'm wondering what's the best data structure for holding a 2D grid of unknown size. The grid has integer coordinates (x,y), and will have negative indices in both directions. So, what is the best way to hold this grid? I'm programming in c# currently, so I can't have negative array indices. My initial thought was to have class with 4 separate arrays for (+x,+y),(+x,-y),(-x,+y), and (-x,-y). This seems to be a valid way to implement the grid, but it does seem like I'm over-engineering the solution, and array resizing will be a headache. Another idea was to keep track of the center-point of the array and set that as the topological (0,0), however I would have the issue of having to do a shift to every element of the grid when repeatedly adding to the top-left of the grid, which would be similar to grid resizing though in all likelihood more frequent. Thoughts?

• Unistalled C++ Redistributables on Windows Vista

  - by VusP

  Windows Vista Service Pack2 32 bit I uninstalled C++ re-distrubutables (was not aware they are necessary for some applications to run) and I am facing error Cannot start application because the side-by-side configuration is not correct when i start applications like Avast, Revo Uninstaller etc. I came across this page. But the downloaded vcredist_86.exe doesn't seem to do much. It extracts itself and that's it nothing after that. No error nothing. I just finished installing 300+ MB updates on my system, so i don't want to use the System Restore option [And, I don't know which Restore Point to revert to]. Any other way to get this done?

• Would you embrace a new technology that worked better than a VPN?

  - by Jumpto

  Ok so VPNs have been around for ages. Business has been addicted to them as the only method of securing their home servers with their workstations in the field. Even with all their problems and shortcomings. So my question is this: How likely are you to embrace a new technology that promises to work better, secure better and have more features than a VPN? State your reasons for or against. Extra points if you point out what steps the new technology would have to take to knock VPN off its throne.

• Network randomly drops

  - by user147661

  I have a VPS, ubuntu server 12.04 and for unknown reasons the network connection drops and I have to access my vps via the console and ifdown eth0 and ifup eth0. This brings the connection back up from about a few seconds to a few hours. I have run tail -F /var/log/syslog to monitor the log to see what happens at the point of drop and there is nothing unusual. The vps is running under virt-manager and the hardware is set to virtio. I have had linux friends look at my vps and they are unsure of what is the cause.

• What happened to the ability to go back in a already-loaded YouTube video?

  - by Chelonian

  For many years, my experience with YouTube had been, consistently and on any computer/browser, that once a section of that video were loaded, or the whole video, if you wanted to see an earlier part of the video again, you could simply click on the loading bar to that area and you would instantly go to that part. More recently (6 months?) this has changed. Now, clicking in an earlier part of the video forces a reload of the whole video (that is, the grey bar goes back to 0) and you have to hope your loading will be fast enough to make waiting to watch it again even worth it. It is a huge regression in usability for me. Is there any way to watch YouTube videos in the "old way"? I use Firefox 17.0.1 at this point and have an updated (I think) Flash, but I'd be willing to try other browsers or versions if it made a difference.

• Can I restore closed tabs after quitting Chrome?

  - by Sammy

  I closed Chrome by accident. Now all the tabs I had open are presumably gone. I don't want to risk anything by starting Chrome now before asking for help. I fear that they will be permanently lost (overwritten files) if I do that. I know from past experience with Firefox that restoring tabs and browser sessions can be a tricky business. What can I do at this point? Is there a file or something I need to copy or rename? I know about the Ctrl+Shift+T command. But I normally use this while browsing. Will this work AFTER closing Chrome?

• Rebuilding a file if files have changed

  - by Todd Strauch

  I'm having a hard time wrapping my head around this. It seems trivial, but I'm not getting it. I have two files. If either of those two files changes, I want to rebuild one of them. Essentially: if file a changes or file b changes then file {"a": content => template('a.erb', 'b.erb'), } I know I can audit a file for change, I just don't know how to include that within a conditional. Can anyone point me in the right direction?

• direct url to server ip address and port

  - by AM0

  We have a Windows 2012 dedicated server. There’s a custom service running on port xxxxx which accepts connections from our custom built hardware devices over TCP/IP port. As of now we use servername.serverdomain.com:xxxxx to connect to the service and start communication. However, we prefer to use URL instead of server’s name or IP Address. So we got a custom url and set its name servers to point to dedicated server. However, just setting DNS doesn’t seem to be working. Could someone please guide as to how to get it working? UPDATE In short I want www.custom-url.com being forwarded to servername.serverdomain.com:xxxxx. These requests are coming from hardware and not browser.

• How to get the level and position of the player from an extern program? [on hold]

  - by user3727174

  I want to write a program that needs the current level and position of the player (primary single player). This should work for potentially every game installed and running on the computer my program is running on. The data I need is basically one integer value for the level (if there are any) and three integer values for x, y and optimal z for the position of the player. In which relation/scale or where the null point is does not matter, because this information is going to be interpreted game dependent, I will use this information to read information out of a database created for the game currently running. Currently I'm using C++, but if there is a better option for Java I´m willing to port my program. My thoughs so far are: make a mod for every game that should be supported, get the position/level from there, write this information to the disk and read it from my program tracking mouse/keyboard events and reconstructing the movement won't work Are there any general APIs for something like this? Any Tool to find this data? Or maybe engines that provide APIs to get this data directly from the game?

• How do I automate the handling of a problem (no network device found) in Ubuntu 10.04 w/ preseed?

  - by user61183

  I have a preseed file that is doing some automation for an installation of Ubuntu 10.04. At the point where the network hardware is auto-detected, however, it fails to find hardware and displays a message, "No network interfaces detected". To make a long story short, I don't care if it can detect my network interface. How do I do one of the following: Skip that step alltogether. Handle the error page automagically. PS. I found somewhere where it suggested this: netcfg/no_interfaces seen true That didn't work. Thanks

• Phishing attack stuck with jsp loginAction.do page? [closed]

  - by user970533

  I 'm testing a phishing website on a staged replica of an jsp web-application. I'm doing the usual attack which involves changing the post and action field of source code to divert to my own written jsp script capture the logins and redirect the victim to the original website. It looks easy but trust me its has been me more then 2 weeks I cannot write the logins to the text file. I have tested the jsp page on my local wamp server it works fine. In staged when I click on the ok button for user/password field I'm taken to loginAction.do script. I checked this using tamper data add on on firefox. The only way I was able to make my script run was to use burp proxy intercept the request and change action parameter to refer my uploaded script. I want to know what does an loginAction.do? I have googled it - its quite common to see it in jsp application. I have checked the code; there is nothing that tells me why the page always point to the .do script instead of mine. Is there some kind of redirection in tomcat configuration. I like to know. I'm unable to exploit this attack vector? I need the community help

• Hardware needed for 2000 users? [closed]

  - by Trcx

  I have school assignment that is fairly well defined, requiring us to come up with a plan for an environment serving dynamic web applications to 2000 users, and should be able to scale up to six thousand. I have done plenty of research as far as load balancing, redundancy, UPSs, etc, but am having a hard time figuring out how much hardware is actually needed in the way of physical servers, ram, processing power, etc. The assignment states that the server will have a lot of dynamic code, email, and a database are required, all utilizing the appropriate microsoft service (MS SQL, Exchange, IIS). I already plan on splitting them out on to separate servers, but can't even fathom the hardware requirements of something that large scale. Could someone with experience weight in on this, or point me two some good articles?

• Excel macro to delete empty rows isn't stopping

  - by RocketGoal

  How do I make it stop after a certain amount of rows? I've taken a VBA course and my teacher explained how to delete empty rows. I'm now trying to put this in place but my macro isn't stopping. I thought I had limited it to 200 rows. I'm missing something important. Any pointers much appreciated. Sub RemoveRows() ' Remove rows from last blank cell Dim LastRow As Long Dim ISEmpty As Long 'Count how many records in the list. This is done so that the Do loop has a finish point. LastRow = Range("A200").End(xlUp).Row 'Start at the top of the list Range("A1").Select 'Loop until the end of the list Do While ActiveCell.Row < LastRow 'Assign number of non empty cells in the row ISEmpty = Application.CountA(ActiveCell.EntireRow) 'If ISEmpty = 0 then delete the row, if not move down a cell into the next row If ISEmpty = 0 Then ActiveCell.EntireRow.Delete Else ActiveCell.Offset(1, 0).Select End If Loop End Sub

• svn:externals cache and stale URLs

  - by dcaunt

  I have a subversion externals entry in a library folder which looks like this: Z https://svn/Z/trunk/library/Z Fetching external item into '/home/releases/50/library/Z' svn: OPTIONS of 'http://svn/repo/trunk/library/Z': could not connect to server (http://svn) The externals URL was the same, but over the HTTP protocol. Having changed the externals to point to the HTTPS, I can't figure out why subversion is still trying to use the old URL. Does subversion cache the externals path, and if so how can I clear this? If not, what else could be causing this? I can check out from the correct (HTTPS) URL fine from the server. NOTE: svn is an entry in the server's local hosts file, pointing to our subversion server's IP.

• mod_rewrite not working after upgrade to 12.10

  - by CrowderSoup

  I'm hoping this is a quick and simple fix and that I just need a fresh set of eyes. However, I'm fearful that it might actually be an error in the latest build of the rewrite module. I have a .htaccess file that turns on the rewrite engine (I've made sure the module is enabled), creates some rewrite conditions, and finally a rewrite rule. Here's my .htaccess file for reference: <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?request=$1 [L,QSA,NC] </IfModule> Now for the problem: if I go to hostname.com it works fine. If I go to hostname.com/Index it works fine. However, if I go to hostname.com/index it doesn't rewrite the request and I get a 404. I'm not sure what's going on here. I've used a rewrite rule tester and there doesn't appear to be any issues with my rewrite rule itself. Again, this issue didn't manifest until after I upgraded to 12.10, at which point I know that Apache was updated. Any thoughts? Has anyone else here experienced this? I know that two other people besides myself have experienced this here. Thanks in advance for any help you can provide!

• Block a Server from reaching a machine

  - by user

  I have a Windows 2003 server that I want to block from accessing a specific IP address. I want to control this from the Server. because I control the machine. The traffic is http traffic (webservice call). It uses a non-standard port, so IP address+ Port combination would also work. Background: I have a development enviornment that for some reason is ignoring host file enteries under some circumstances. These host files point the enviornment at services in another Dev enviornment. Wne th host files are ignored, dev is talking to production. This is not my question, rather the motivation for this inquiry. I want is a failsafe to ensure dev will error instead of happily engaging in transactions with production. I control the dev server, I do not control the firewalls or the target production machine.
