• How do i know if i set up the nlb (network load balancing) cluster correctly???

  - by letseatlunch

  So ill start from the very beginning. I'm working on a web conference were we are going to show about 12 videos for a total of about half a gig for all 12. Since all the participants are going to be watching (and also streaming/downloading) at once it was recommended we set up a server farm. So i have 4 servers that i am trying to network together. They are all running Microsoft Server 2008 and i have spent the last three days setting them up and now that its done i want to make sure its all ready to go. so i just want to be sure that everything is setup the way that i think it is. What is the best way to do this. Really i want to make sure that the load will be split over the servers when its showtime. thanks for any help in advance letseatlunch Dave

• How to set up a local webDAV server for use with Goodreader on the ipad?

  - by confused-about-webdav

  I need to know how to set up a local webDav server on my PC so that goodreader on ipad can automatically sync with it over the local wifi network? I am really a rookie when it comes to setting up a web server and have tried various guides on the internet. I tried setting up a webdav server using IIS and forwarded the required ports and enabled webdav publishing but goodreader can find it in the local wifi network automatically nor is it able to connect even after manually entering the credendtials. So i'll be really greateful if someone who has successfully setup a webdav server for use with goodreader can point me on how to do it?

• I'm trying to set up a LAMP server so it's totally anonymous, any suggestions?

  - by flexterra

  I'm going to set up a web service which will use the LAMP stack. One of the most important features of the site is that it should be anonymous. We thought that a cool thing will be if the server didn't made any logs that could potentially identify a user. I'm working on a web app for a news organization. They want a site to allow people to sumbit news leads and tips (text / files) to journalists. We think if we can provide good anonymity people will be more inclined to provide information. We will also teach how to use stuff like TOR as an extra precaution for whistleblowers Is this even possible? Any suggestions of obscure things we should look into?

• FeedDaemon and Tweetdeck not opening links in Chrome but opening in IE when IE is set default browser

  - by user2059078

  A while ago a Chrome version update failed and I ended up having a program called new_chrome.exe in the folder where chrome.exe used to be. I was very busy at that moment and I continued to work without bothering to try to fix the problem. Apparently recently another update came out and the new_chrome.exe is now gone, it was replaced by chrome.exe. Since the last upgrade happened two applications that I use a lot (not sure if others do the same) do now work anymore as they used to when I try to open links. These two apps are Tweetdek and Feedaemon. If I change the default browser to Internet Explorer they both open the links when I click on them I tried everything I could but it did not work: My Default programs look like this: and my set Default Programs looks like this: How can I fix this?

• How can I let my users set PHP.ini settings for wordpress?

  - by jldugger

  I set up a wordpress server from a fairly standard Ubuntu 9.10 for a class and they're constantly running into problems with the default PHP.ini settings. First memory settings were too low, then the file upload limits were too small, etc. And more concerning was a wordpress wide blank page that I suspect was killed for ram consumption but turning on php errors in php.ini didn't reveal anything! I'm not familiar with shared hosting, but I feel there's a way such places allow users to edit such things without needing me to intervene and restart Apache.

• HP Pavilion dv6 overheating, how do I set fan speed to 100% all the time?

  - by henpenben

  So I have a HP Pavilion dv6, and it works fine. But when I play, say, Minecraft, the temperature jumps to around 60c-70c. I wouldn't be bothered by this, but I bought this computer and played Minecraft on my lap. The laptop overheated and the video card melted. (I'm not kidding) So I was wondering how I could set the fan speed on my laptop to 100% all the time so it never overheats. HP has this "HP Coolsense" thing that when I pick up the laptop and wiggle it around a little bit and pretend it's unstable, the fan cranks up to 100%. I want 100% all the time without me having to pick up the laptop every 10 minutes. Thanks, henpenben

• Need ability to set configuration options using single method which will work across multiple server configurations.

  - by JMC Creative

  I'm trying to set post_max_size and upload_max_filesize in a specific directory for a web application I'm building. I've tried the following in a .htaccess file in the script directory. (upload.php is the script that needs the special configuration) <Files upload.php> php_value upload_max_filesize 9998M php_value post_max_size 9999M </Files> That doesn't work at all. I've tried it without the scriptname specificity, where the only thing in the .htaccess file is: php_value upload_max_filesize 9998M php_value post_max_size 9999M This works on my pc-based xampp server, but throws a "500 Misconfiguration Error" on my production server. I've tried also creating a php.ini file in the directory with: post_max_size = 9999M upload_max_filesize = 9998M But this also doesn't always work. And lastly using the following in the php script doesn't work either, supposedly because the settings have already been compiled by the time the parser reaches the line (?): <?php ini_set('post_max_size','9999M'); ini_set('upload_max_filesize','9998M'); ?>

• How can I set `less` or `more` max lines (scrollable height) limit/boundary in linux?

  - by Rudie

  (Sorry for the title. Any suggestions?) I've set my commandline PS1 to cover 3 lines: white space user, server and pwd $ or # to input I think less (or more?) is configured to break after window's height - 1, because when I do a $ git log, the first two lines are invisible at the top of the window and the rest is scrollable. I'm not sure who handles this scrolling and its configuration, but I assume GIT uses less/more. Where can I configure that my scrollable window is window height - 3 lines and not window height - 1? More info: If I cat lines.txt | less with a 23 line file, it shows the entire file and no scrolling. If I do the same with a 24 line file, it doesn't show line 1 (and no scrolling). With 25 lines: doesn't show lines 1 and 2 (and no scrolling). With 26 lines: shows line 1 and scrolling! The less breakpoint is at the wrong height...

• How do I set up a proxy server for home with bandwidth control, download limit options?

  - by Quakeboy

  3 room mates share a single 2 Mbps connection. Have a 40GB per month download limit beyond which speed drops to 256Kbps which is annoying. One of the roommates abuses the connection by downloading beyond his quota limit. I have a Netgear WNR1000v2 Wireless router + ADSL Modem to connect to the internet. We all access internet via Wireless router which connects to ADSL Modem. I need a free proxy solution which can help me set 40GB / 3 (13 GB) limit for each person (every person has 2 devices - a PC and a phone with Wifi) Uniform Bandwidth control - when 2 people browse the internet they should get 1 Mbps each, and when 3 people access, they should get 2Mbps divided by 3. After each person crosses their monthly download limit, they should be able to access the internet with 256Kbps speed only or lesser. Can I have a custom firmware on my wireless router do this (or) Do I need a proxy server ? Please point me to any relevant tutorials (for example with Squid).

• In mysql I want to set lower_case_table_names=1 on existing databases to avoid cases-sensitivity issues accross multiple platforms

  - by sakhunzai

  In mysql I want to set lower_case_table_names=1 on existing databases to avoid cases-sensitivity issues accross multiple platforms. A) What are the risks ?( besides show table issue) B) After setting lower_case_table_names=1, will I be in position to query databases across multiple platforms consistantly ? select * from USERS == select * from users; C) How the triggers + stored procedure + functions + views + events will be affected in this regards. I know lower_case_table_names is only for "TABLE" names but how about triggers other database objects . Will they remain case-insensitive How about views ? D) Do I need to rename all tables before/after this configuration setting or this will do the miracle in one step (i.e lower_case_table_names=1 neutralize table names) ? E) What will be the exact steps WRT:mysqd / my.ini ?

• Can OpenVPN be set up so the server doesn't have interface that is part of the VPN?

  - by BCS

  I'm looking to set up a VPN (OpenVPN is my first choice but I'm not stuck with it) in such a way that the server that hosts the VPN is not visible from within the VPN. That is; any packet that a client sends via the VPN interface will get delivered to another client's VPN interface or get dropped. In the other direction, the server shouldn't have a VPN interface at all and normal network operations shouldn't be able to send packets on the network. Can this be done? All the docs I have found have assumed that clients will connect via DHCP (this requiring that the server connect at least to that extent) but I can't think of any reason that a VPN couldn't use static IP's or that the DHCP server couldn't be implemented inside the VPN (see edit) server without setting up a VPN interface on the server. Edit: Based on the link on bridged mode from Phil Hollenback's answer it seems that OpenVPN does in fact have the "internal DHCP server" that I'm thinking of.

• How do I set up a mailing list for over 2000 people?

  - by John Hoffman

  I manage IT for a large organization with over 2000 people. The administration would like to send an email (often with up to 5 word document attachments) about once per week. They also want to categorize people. For instance, about 40 people are "teachers," about 1800 people are "students," and about 10 people are "board members." They may send an email to any combination of these categories. Here's what I have tried: I bought a server, installed Ubuntu server edition on it, and wrote a python script to send out their emails. However, pretty soon, mail services such as Gmail and Yahoo began to treat the mail I send out as SPAM. I'm guessing this is because I am sending an email with 2000+ people in the "bcc" field. Maintaining this server also takes a lot of time. How do I set up a mailing list for over 2000 people? Must I defer to paid services?

• Authlogic openid: getting undefined method openid_identifier? error in functional test

  - by usr

  I use Authlogic with the Authlogic-openid addon (I gem installed ruby- openid and script/plugin install git://github.com/rails/open_id_authentication.git) and get two errors. First when running functional test, I get an undefined method openid_identifier? message on a line in my new.html.erb file when running the UsersControllerTest. The line is: <% if @user.openid_identifier? %> When running script/console I can access this method without any problem. Second when testing the openid functionality and registering a new user to my application using openid and using my blogspot account for that I get the following in my log file: Generated checkid_setup request to http://www.blogger.com/openid-server.g with assocication ...

• What is the most effective way to test for combined keyboard arrow direction in ActionScript 3.0?

  - by Relee

  I need to monitor the direction a user is indicating using the four directional arrow keys on a keyboard in ActionScript 3.0 and I want to know the most efficient and effective way to do this. I've got several ideas of how to do it, and I'm not sure which would be best. I've found that when tracking Keyboard.KEY_DOWN events, the event repeats as long as the key is down, so the event function is repeated as well. This broke the method I had originally chosen to use, and the methods I've been able to think of require a lot of comparison operators. The best way I've been able to think of would be to use bitwise operators on a uint variable. Here's what I'm thinking var _direction:uint = 0x0; // The Current Direction That's the current direction variable. In the Keyboard.KEY_DOWN event handler I'll have it check what key is down, and use a bitwise AND operation to see if it's already toggled on, and if it's not, I'll add it in using basic addition. So, up would be 0x1 and down would be 0x2 and both up and down would be 0x3, for example. It would look something like this: private function keyDownHandler(e:KeyboardEvent):void { switch(e.keyCode) { case Keyboard.UP: if(!(_direction & 0x1)) _direction += 0x1; break; case Keyboard.DOWN: if(!(_direction & 0x2)) _direction += 0x2; break; // And So On... } } The keyUpHandler wouldn't need the if operation since it only triggers once when the key goes up, instead of repeating. I'll be able to test the current direction by using a switch statement labeled with numbers from 0 to 15 for the sixteen possible combinations. That should work, but it doesn't seem terribly elegant to me, given all of the if statements in the repeating keyDown event handler, and the huge switch. private function checkDirection():void { switch(_direction) { case 0: // Center break; case 1: // Up break; case 2: // Down break; case 3: // Up and Down break; case 4: // Left break; // And So On... } } Is there a better way to do this?

• Still failing a function, not sure why...ideas on test cases to run?

  - by igor

  I've been trying to get this Sudoku game working, and I am still failing some of the individual functions. All together the game works, but when I run it through an "autograder", some test cases fail.. Currently I am stuck on the following function, placeValue, failing. I do have the output that I get vs. what the correct one should be, but am confused..what is something going on? EDIT: I do not know what input/calls they make to the function. What happens is that "invalid row" is outputted after every placeValue call, and I can't trace why.. Here is the output (mine + correct one) if it's at all helpful: http://pastebin.com/Wd3P3nDA Here is placeValue, and following is getCoords that placeValue calls.. void placeValue(Square board[BOARD_SIZE][BOARD_SIZE]) { int x,y,value; if(getCoords(x,y)) { cin>>value; if(board[x][y].permanent) { cout<< endl << "That location cannot be changed"; } else if(!(value>=1 && value<=9)) { cout << "Invalid number"<< endl; clearInput(); } else if(validMove(board, x, y, value)) { board[x][y].number=value; } } } bool getCoords(int & x, int & y) { char row; y=0; cin>>row>>y; x = static_cast<int>(toupper(row)); if (isalpha(row) && (x >= 'A' && x <= 'I') && y >= 1 && y <= 9) { x = x - 'A'; // converts x from a letter to corresponding index in matrix y = y - 1; // converts y to corresponding index in matrix return (true); } else if (!(x >= 'A' && x <= 'I')) { cout<<"Invalid row"<<endl; clearInput(); return false; } else { cout<<"Invalid column"<<endl; clearInput(); return false; } }

• Can I write a test that succeeds if and only if a statement does not compile?

  - by Billy ONeal

  I'd like to prevent clients of my class from doing something stupid. To that end, I have used the type system, and made my class only accept specific types as input. Consider the following example (Not real code, I've left off things like virtual destructors for the sake of example): class MyDataChunk { //Look Ma! Implementation! }; class Sink; class Source { virtual void Run() = 0; Sink *next_; void SetNext(Sink *next) { next_ = next; } }; class Sink { virtual void GiveMeAChunk(const MyDataChunk& data) { //Impl }; }; class In { virtual void Run { //Impl } }; class Out { }; //Note how filter and sorter have the same declaration. Concrete classes //will inherit from them. The seperate names are there to ensure only //that some idiot doesn't go in and put in a filter where someone expects //a sorter, etc. class Filter : public Source, public Sink { //Drop objects from the chain-of-command pattern that don't match a particular //criterion. }; class Sorter : public Source, public Sink { //Sorts inputs to outputs. There are different sorters because someone might //want to sort by filename, size, date, etc... }; class MyClass { In i; Out o; Filter f; Sorter s; public: //Functions to set i, o, f, and s void Execute() { i.SetNext(f); f.SetNext(s); s.SetNext(o); i.Run(); } }; What I don't want is for somebody to come back later and go, "Hey, look! Sorter and Filter have the same signature. I can make a common one that does both!", thus breaking the semantic difference MyClass requires. Is this a common kind of requirement, and if so, how might I implement a test for it?

• Capistrano asks for SSH password when deploying from local machine to server

  When I try to ssh to a server, I'm able to do it as my id_rsa.pub key is added to the authorized keys in the server.

• Unit Tests in Visual Studio 2010

  - by Ben

  Hi, i am trying to create a Unit test for a WinForm in a Visual Studio 2010 project. I add a new "Coded UI Test" to my project, open up the code file, then right click and select "Generate Code for Coded UI Test" - "Use Coded UI Test builder". I then start my application up, select "Record" on the UI Map control. I run my tests (in this case simply select a textbox, type in a random value, them click a button). I then select "Generate Code" from the UI Map control which generates the code which the test will use. When running this test, i get the error: Test method HelloWorldTest.CodedUITest1.CodedUITestMethod1 threw exception: Microsoft.VisualStudio.TestTools.UITest.Extension.UITestControlNotFoundException: The playback failed to find the control with the given search properties. Additional Details: TechnologyName: 'MSAA' ControlType: 'Window' Name: 'Form1' ClassName: 'WindowsForms10.Window' --- System.Runtime.InteropServices.COMException: Error HRESULT E_FAIL has been returned from a call to a COM component. Does anyone know where i am going wrong? Thanks

• In a Rails unit test, how can I get a User fixture to load its associated Profile?

  - by MikeJ

  In the documentation concerning Fixtures (http://api.rubyonrails.org/classes/Fixtures.html) they provide the following example of using label references for associations: ### in pirates.yml reginald: name: Reginald the Pirate monkey: george ### in monkeys.yml george: name: George the Monkey pirate: reginald So following their lead, I have a User model that has_one :profile, a Profile model that belongs_to :user, and tried to set up fixtures per their example: ### in users.yml reginald: id: 1 login: reginald ### in profiles.yml reginalds_profile: id: 1 name: Reginald the Pirate user: reginald (Note: since my association is one-way, the User fixture doesn't have a "profile: reginalds_profile" association--putting it in causes an error because the SQL table has no profile_id attribute.) The problem is, in my unit tests everything seems to load correctly, but users(:reginald).profile is always nil. What am I missing?

• regex to match trailing whitespace, but not lines which are entirely whitespace (indent placeholders

  - by Tim

  I've been trying to construct a ruby regex which matches trailing spaces - but not indentation placeholders - so I can gsub them out. I had this /\b[\t ]+$/ and it was working a treat until I realised it only works when the line ends are [a-zA-Z]. :-( So I evolved it into this /(?!^[\t ]+)[\t ]+$/ and it seems like it's getting better, but it still doesn't work properly. I've spent hours trying to get this to work to no avail. Please help. Here's some text test so it's easy to throw into Rubular, but the indent lines are getting stripped so it'll need a few spaces and/or tabs. Once lines 3 & 4 have spaces back in, it shouldn't match on lines 3-5, 7, 9. some test test some test test some other test (text) some other test (text) likely here{ dfdf } likely here{ dfdf } and this ; and this ; Alternatively, is there an simpler / more elegant way to do this?

• emacs: Can I set compilation-error-regexp-alist in a mode hook fn?

  I am trying to set the compilation-error-regexp-alist in a function that I add as a mode hook.

The various things I Set in the mode hook work. The compile-command gets set. But for some reason, the compilation-error-regexp-alist value doesn't take effect. If I later do a M-x describe-variable on compilation-error-regexp-alist, it shows me the value I think it should have. But .. the errors in the compilation buffer don't get highlighted, and M-x next-error does not work. If I add the error regexp value to the compilation-error-regexp-alist via setq-default, like this: (setq-default compilation-error-regexp-alist '( ... jslint regexp here ... ... many other regexp's here... )) ...then it works. The errors in the compilation buffer get properly highlighted and M-x next-error functions as expected.

• Bad Practice requiring file within a model?

  - by Lee Marshall

  I have built an MVC php application and was wondering, if instead of having to write out a large amount of html and set the data, could I not just have all this html (with some php) in a separate file and just require it? For example: $test = '<div> Test content <div>More content</div> </div>'; $APP->Template->setData('test', $test, FALSE); Instead could I not just use: $test = require("includes/content.php"); $APP->Template->setData('test', $test, FALSE); Would this be considered as bad practise? It just seems that by requiring files, it can shorten the length of controllers. Would be good to get anybodies advice on this matter.

• How to set up a user Quartz2D coordinate system with scaling that avoids fuzzy drawing?

  - by jdmuys

  This topic has been scratched once or twice, but I am still puzzled. And Google was not friendly either. Since Quartz allows for arbitrary coordinate systems using affine transform, I want to be able to draw things such as floorplans using real-life coordinate, e.g. feet. So basically, for the sake of an example, I want to scale the view so that when I draw a 10x10 rectangle (think a 1-inch box for example), I get a 60x60 pixels rectangle. It works, except the rectangle I get is quite fuzzy. Another question here got an answer that explains why. However, I'm not sure I understood that reason why, and moreover, I don't know how to fix it. Here is my code: I set my coordinate system in my awakeFromNib custom view method: - (void) awakeFromNib { CGAffineTransform scale = CGAffineTransformMakeScale(6.0, 6.0); self.transform = scale; } And here is my draw routine: - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGRect r = CGRectMake(10., 10., 11., 11.); CGFloat lineWidth = 1.0; CGContextStrokeRectWithWidth(context, r, lineWidth); } The square I get is scaled just fine, but totally fuzzy. Playing with lineWidth doesn't help: when lineWidth is set smaller, it gets lighter, but not crisper. So is there a way to set up a view to have a scaled coordinate system, so that I can use my domain coordinates? Or should I go back and implementing scaling in my drawing routines? Note that this issue doesn't occur for translation or rotation. Thanks

• HTML <select> selected option background-color CSS style

  - by arieltools

  Is there a style for a select option's "selected" color? For example: <HTML> <BODY> <FORM NAME="form1"> <SELECT NAME="mySelect" SIZE="7" style="background-color:red;"> <OPTION>Test 1 <OPTION>Test 2 <OPTION>Test 3 <OPTION>Test 4 <OPTION>Test 5 <OPTION>Test 6 <OPTION>Test 7 </SELECT> </FORM> </BODY> </HTML> When I select an option it turns blue, I want to override this and make it a different color. In the style I expected something like "selected-color", but it doesn't exist.
