• Can't access a partion that has a virus on it

  - by vaccano

  My wife's computer had a virus alarm go off, so I am looking into it. The virus is supposed to be on the D: drive. I wanted to talk a quick look at the file, but I cannot not. It has one file that I can get to. It is D:\Recovery. That shows a "Protected by PC Angel" graphic. How can I get past this? Should I do it? Is the virus scanner wrong? (I am using Avast).

• haproxy access list using path_dir having issues with firefox

  - by user11243

  I'm trying to route all requests containing a path directory of /socket.io/ to a separate port with HAProxy. Here is my config file: global maxconn 4096 # Total Max Connections. This is dependent on ulimit nbproc 2 defaults mode http frontend all 0.0.0.0:80 timeout client 86400000 default_backend web_servers acl is_stream path_dir socket.io use_backend stream_servers if is_stream backend web_servers balance roundrobin option forwardfor # This sets X-Forwarded-For timeout server 30000 timeout connect 4000 server web1 127.0.0.1:4000 weight 1 maxconn 1024 check backend stream_servers balance roundrobin option forwardfor # This sets X-Forwarded-For timeout queue 5000 timeout server 86400000 timeout connect 86400000 server stream1 127.0.0.1:5100 weight 1 maxconn 1024 check URL paths with a /socket.io/ get correctly directed to port 5100 in chrome and safari.

I've tried clearing cache on firefox and it didn't help, so I'm thinking there's something wrong with the way HAProxy parses through the Firefox request headers.

• Remote access to Microsoft Dynamics NAV (C/Side) with native non-SQL database

  - by Joannes Vermorel

  I am facing a company that have a fairly recent Microsoft Dynamics NAV (C/Side) setup that comes with a non-SQL storage system called the native database server. I would need to be remotely connect to this database, and perform what would equate to SQL queries with very modest needs (no join, no complex filtering). I am rather ignorant of this technology, does someone knows to how make remote queries to this ERP?

• Games consoles won't connect through the TP-Link TL-WA500G Access Point

  - by Manfred Wolff

  I hope that someone can help me. I have several Laptops and other devices, all using my Wireless Router (Sky Digital Netgear) To extend the range to the back of the house, I purchased a TP-Link TL-WA500G Range extender. configured just as a pure repeater, it picks up the signal from the Netgear Router. The Netgear Router does the DHCP, handing out the IP addresses. This all works a treat with several different laptops and my iPone4S, but when my son tries to use his XBox360, Sony Playstation3 or the Nintendo Wii those devices fail to acquire an IP address. They just sit their waiting for the IP config. This also happens with my wife's HTC desire ONE Android phone. My son says that, when his HTC Desire C won't get an IP address, he just unplugs the AP briefly - the phone will connect and he puts the AP back on. Once he is connected to the Router, the AP won't disturb function. The Games Consoles don't seem to work like that. They stop working, when the AP is reconnected. I had my son try to configure permanent IP addresses, and he said that did not work either, though I have to confirm that, as I did not see that for myself. Has anybody seen this before? I have searched the Net and have not found any similar problems anywhere. I wonder if there is setting somewhere that would fix this. Many thanks for anyone reading this and trying to help. M

• "Error 5: Access denied" when installing programs with UAC turned off

  - by Aero

  I'm having some trouble installing msysgit 1.7.3.1preview on Windows 7 Home Premium. I downloaded the setup file from the Google Code and then ran it. Upon running, I got the following error: I have tried downloading and running different older versions of msysgit with no luck. For the record, I have administrative privileges and there are no other user accounts on this Windows machine. Any help would be greatly appreciated. Thanks. UPDATE: I have managed to semi-fix this problem. I turned on User Account Control back to the default setting and and then ran the setup file as an administrator. I successfully managed to install Git. However, this means I have to keep UAC turned on whenever I want to install a new program (I realised that it persists over all programs; not just Git). So it's quite a nuisance. If anybody knows how I could keep UAC disabled whilst still being able to install programs without running their setup files as an administrator, I would be eternally grateful. UPDATE: I have changed the question title to better suit the new situation.

• Restricting access to one controller of an MVC app with Nginx

  - by kgb

  I have an MVC app where one controller needs to be accessible only from several ips(this controller is an oauth token callback trap - for google/fb api tokens). My conf looks like this: geo $oauth { default 0; 87.240.156.0/24 1; 87.240.131.0/24 1; } server { listen 80; server_name some.server.name.tld default_server; root /home/user/path; index index.php; location /oauth { deny all; if ($oauth) { rewrite ^(.*)$ /index.php last; } } location / { if ($request_filename !~ "\.(phtml|html|htm|jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|xlsx)$") { rewrite ^(.*)$ /index.php last; break; } } location ~ \.php$ { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; } } It works, but does not look right. The following seems logical to me: location /oauth { allow 87.240.156.0/24; deny all; rewrite ^(.*)$ /index.php last; } But this way rewrite happens all the time, allow and deny directives are ignored. I don't understand why...

• Windows 7 - saved wifi access points disappear from list

  - by KáGé

  I'm having a weird issue with Windows 7 x64: I'm moving my notebook between two locations weekly, at each I have a wifi router. They both have hidden SSID-s, which are different. If I save one, the other one gets deleted from the list, as if overwritten, so I always have to retype the SSID and password, if I want to connect after moving my computer. At first I tought the problem was caused by both routers having the same password, but after I changed one (suffixed it with "_2") it persisted. What can I do about this? Thanks.

• remote desktop access

  - by pnp

  I have my work system on the ip range 172.16.xx.yy, and I have my personal system on the ip range 10.0.xx.yy. Both of them, however, are on the same network of my University, but on different LANs/VLANs (i hope i used the right word here). How can I remotely connect to my work system from my PC, given that both use private IP addresses? If such a thing is not possible with current set up, what minimal changes are required for it?

• Repeated calls with random Javascript append to the URL

  - by cjk

  I keep getting calls to my server where there is random Javascript appended on the end of lots of the calls, e.g.: /UI/Includes/JavaScript/).length)&&e.error( /UI/Includes/JavaScript/,C,!1),a.addEventListener( /UI/Includes/JavaScript/),l=b.createDocumentFragment(),m=b.documentElement,n=m.firstChild,o=b.createElement( /UI/Includes/JavaScript/&&a.getAttributeNode( /UI/Includes/JavaScript/&&a.firstChild.getAttribute( /UI/Includes/JavaScript/).replace(bd, /UI/Includes/JavaScript/)),a.getElementsByTagName( The user agent is always this: Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+2.0.50727) I have jQuery, Modernizr and other JS and originally thought that some browser was messing up it's JS calls, however this particular IP address hasn't requested any images so I'm wondering if it is some kind of attack. Is this a common occurence?

• 12.04 Random sounds sometimes after startup

  - by Timothy Duane

  I'm not quite sure what the sound is, but it has only started happening in the last two days. The only way I can describe it would be that it sounds like a wooden xylophone being tapped lightly. It will play at random intervals ranging between 1 second to a couple minutes for up to a half hour (from what I have noticed) after startup. If anybody has any ideas as to what is causing this or how to fix it I would appreciate it.

• Execure a random command from .txt file?

  - by Alberto Burgos

  I have a Ubuntu server, and I'm trying to print a Twitter quote using the app "twidge". So I made a list of tweets on a .txt file. I want to print one tweet (per line) from that file and send it to Twitter via twidge (or what ever other method was possible). I can print a random phrase with shuf: shuf -n 1 /var/www/tweets.txt and it works. It sends me back one of the tweets, but, it does not send it to Twitter, even if the "in line" phrase is a command. i.e: twidge update "bla bla bla" It just prints on the screen, but don't send it to Twitter. I tried turning the .txt to .sh, but don't work... any idea? by the way, i want to use it with crontab, something like this: 15 * * * * shuf -n 1 /var/www/tweets.txt

• Random freezes on MBP9,2 + Ubuntu 12.04

  - by EnToutCas

  I have a MBP9,2 (mid-2012) at work. I put Ubuntu 12.04 on it after some efforts. Everything works more or less now, except I get random freezing every now and then. I have to power off the machine to restore it. Wondering if anyone had the similar issue. My setup: MacBook Pro 9,2 (mid 2012) Ubuntu 12.04 (installed using the special image for Macs) No proprietary drivers xmonad on Unity 2D So far the freezes look to be sporadic and spontaneous.

• Random/Procedural vs. Previously Made Level Generation

  - by PythonInProgress

  I am making a game (called "Glory") that is a top-down explorer game, and am wondering what the advantages/disadvantages of using random/procedural generation vs. pre-made levels are. There seems to be few that i can think of, other than the fact that items may be a problem to distribute in randomly generated terrain, and that the generated terrain may look weird. The downside to previously made levels is that I would need to make a level editor, though. I cannot decide what is better to use.

• Algorithm to generate N random numbers between A and B which sum up to X

  - by Shaamaan

  This problem seemed like something which should be solvable with but a few lines of code. Unfortunately, once I actually started to write the thing, I've realized it's not as simple as it sounds. What I need is a set of X random numbers, each of which is between A and B and they all add up to X. The exact variables for the problem I'm facing seem to be even simpler: I need 5 numbers, between -1 and 1 (note: these are decimal numbers), which add up to 1. My initial "few lines of code, should be easy" approach was to randomize 4 numbers between -1 and 1 (which is simple enough), and then make the last one 1-(sum of previous numbers). This quickly proved wrong, as the last number could just as well be larger than 1 or smaller than -1. What would be the best way to approach this problem? PS. Just for reference: I'm using C#, but I don't think it matters. I'm actually having trouble creating a good enough solution for the problem in my head.

• Calculate random points (pixel) within a circle (image)

  - by DMills

  I have an image that contains a circles at a specific location, and of a specific diameter. What I need to do is to be able to calculate random points within the circle, and then manipulate said the pixels they correlate to. I have the following code already: private Point CalculatePoint() { var angle = _random.NextDouble() * ( Math.PI * 2 ); var x = _originX + ( _radius * Math.Cos( angle ) ); var y = _originY + ( _radius * Math.Sin( angle ) ); return new Point( ( int )x, ( int )y ); } And that works fine for finding all the points at the circumference of the circle, but I need all points from anywhere in the circle. If this doesn't make sense let me know and I will do my best to clarify.

• Can I password protect a Publisher file?

  - by tombull89

  I was asked ealier this week if it was possible to password protect a Microsoft Office 2007 Publisher document. I was under the impression that it would be like protecting a Word document, by going to Office Save As Word Document Tools General Options and creating a password to modify, like shown below. This also works for Excel documents. However, in Publisher 2007 the option is not there. The only option under "Tools" is "Map network drive". We overcame the issue as saving as a PDF and distributing that, but is there a way to do what we want?

• Update on: How to model random non-overlapping spheres of non-uniform size in a cube using Matlab?

  - by user3838079

I have ran the code for no. of spheres (n) = 10; dims = [ 10 10 10 ] function [ c r ] = randomSphere( dims ) % creating one sphere at random inside [0..dims(1)]x[0..dims(2)]x... % radius and center coordinates are sampled from a uniform distribution % over the relevant domain. % output: c - center of sphere (vector cx, cy,... ) % r - radius of sphere (scalar) r = rand(1); % you might want to scale this w.r.t dims or other consideration c = r + rand( size(dims) )./( dims - 2*r ); % make sure sphere does not exceed boundaries function ovlp = nonOverlapping( centers, rads ) % check if several spheres with centers and rads overlap or not ovlp = false; if numel( rads ) == 1 return; % nothing to check for a single sphere end dst = sqrt( sum( bsxfun( @minus, permute( centers, [1 3 2] ),... permute( centers, [3 1 2] ) ).^2, 3) ); ovlp = dst >= bsxfun( @plus, rads, rads.' ); %' all distances must be smaller than r1+r2 ovlp = any( ovlp(:) ); % all must not overlap function [centers rads] = sampleSpheres( dims, n ) % dims is assumed to be a row vector of size 1-by-ndim % preallocate ndim = numel(dims); centers = zeros( n, ndim ); rads = zeros( n, 1 ); ii = 1; while ii <= n [centers(ii,:), rads(ii) ] = randomSphere( dims ); if nonOverlapping( centers(1:ii,:), rads(1:ii) ) ii = ii + 1; % accept and move on end end

• Setup Remote Access in Windows Home Server

  - by Mysticgeek

  One of the many awesome features of Windows Home Server, is the ability to access your server and other computers on your network remotely. Today we show you the steps to enable Remote Access to your home server from anywhere you have an Internet connection. Remote Access in Windows Home Server has a lot of great features like uploading and downloading files from shared folders, accessing files from machines on your network, and controling machines remotely (on supported OS versions). Here we take a look at the basics of setting it up, choosing a domain name, and verifying you can connect remotely. Setup Remote Access in Windows Home Server Open the Windows Home Server Console and click on Settings. Next select Remote Access, it is off by default, just click the button to turn it on. Wait while your router is configured for remote access, when it’s complete click Next. Notice that it will enable UPnP, if you don’t wish to have that enabled, you can manually forward the correct ports. If you have any problems with the router being automatically configured, we’ll be taking a look at a more detailed troubleshooting guide in the future. The router is successfully configured, and we can continue to the next process of configuring our domain name. The Domain Name Setup Wizard will start. Notice you will need a Windows Live ID to set it up –which is typically your hotmail address. If you don’t already have one, you can get one here. Type in your Live ID email address and password and click Next… Agree to the Home Server Privacy Statement and the Live Custom Domains Addendum. If you’re concerned about privacy and want to learn more about the domain addendum, make sure to read about it before agreeing. There is nothing abnormal to point out about either statement, but if this is your first time setting it up, it’s good to review the information.   Now choose a name for the domain. You should select something that is easy to remember and identifies your home server. The name can contain up to 63 characters, numbers, letters, and hyphens…and must begin and end with a letter or number. When you have the name figured out click the Confirm button. Note: You can only register one domain name per Live ID. If the name isn’t already taken, you’ll get a confirmation message indicating it’s god to go. The wizard is complete and you can now access the home server from the URL provided. A few other things to point out after you’ve set it up…under Domain Name click on the Details button… Which pulls up the domain detail information and you can refresh the data to verify everything is working correctly. Or you can click the Configure button and then change or release your current domain name. Under Web site settings, you can change you site page headline to whatever you want it to be. Accessing Home Server Remotely After you’ve gotten everything setup for your home server domain, you can begin to access it when you’re away from home. Simply type in the domain address you created in the previous steps. The start page is rather boring…and to start accessing your data, click the Log On button in the upper right hand corner. Then enter in your home server credentials to gain access to your files, folders, and network computers. You won’t be able to log in with your administrator user account however, to protect security of your network. Once you’re logged in, you’ll be able to access different parts of your home server shares and network computers. Conclusion Now that you have Remote Access setup, you should be able to access and manage your files easily. Being able to access data from your home server remotely is great when you need to get certain files while on the road. The web UI is pretty self explanatory, works best in IE as ActiveX is required, and is smooth and easy to work with. In future articles we’ll be covering a lot more regarding remote access, including more of the available features, troubleshooting connection issues, and enabling access for other users.

• Which of the following relational database management systems would a company adopt (for migration), if any, MS Access, MS SQL Server or MySQL?

  - by Hassan Hagi

  Dear programmers, as part of my final year university project, I am conducting research into relational database management systems such as Microsoft Office Access 2007, Microsoft SQL Server 2008 and MySQL 5.1. The description does not need to be detailed however; I am trying to find empirical evidence and professional opinion/fact to determine which of the three databases are best suited for the required size of company (stated or unstated). OS: Microsoft windows (XP or newer) Please consider the following, but full details are not necessary: Memory management Migration Design constraints Integrity (data and others) Triggers User constraints Ease of use Performance Crash Recovery (not the operating system) Total Cost of Ownership (TCO) Also any info on Open source (to do with the three RDBMS) Thank you for your time and help.

• What are best practices for testing programs with stochastic behavior?

  - by John Doucette

  Doing R&D work, I often find myself writing programs that have some large degree of randomness in their behavior. For example, when I work in Genetic Programming, I often write programs that generate and execute arbitrary random source code. A problem with testing such code is that bugs are often intermittent and can be very hard to reproduce. This goes beyond just setting a random seed to the same value and starting execution over. For instance, code might read a message from the kernal ring buffer, and then make conditional jumps on the message contents. Naturally, the ring buffer's state will have changed when one later attempts to reproduce the issue. Even though this behavior is a feature it can trigger other code in unexpected ways, and thus often reveals bugs that unit tests (or human testers) don't find. Are there established best practices for testing systems of this sort? If so, some references would be very helpful. If not, any other suggestions are welcome!

• What is the difference between _Procedural Generation_ and _Random Generation_?

  - by U-No-Poo

  Today, I got into an argument about the term "procedural generation". My point was that its different from "classic" random generation in that procedural generation is based on a more mathematical, fractal-based, algorithm leading to a more "realistic" distribution and the usual randomness of most languages are based on a pseudo-random-number generator, leading to an "unrealistic", in a way, ugly, distribution. This discussion was made with a heightmap in mind. The discussion left me somehow unconvinced about my own arguments though, so, is there more to it? Or am I the one who is, in fact, simply wrong?

• How can I ensure reasonably spaced out enemies

  - by Samuraisoulification

  I have a simple javascript game and I'm initializing their positions on the y axis using random numbers. How can I ensure that they are reasonably spaced apart? My simple algorithm is: y = (Math.random()*1000%600); However I frequently get enemies almost directly on top of each other. This is a huge problem for the game, since it's a word game and the enemies have text on their center, that if overlapped makes them impossible to kill since you can't see the words. Any advice would be appreciated! I'm pretty new to making games in general so this has all been a learning experience for me!
