  • PGP - MailCloak/Gpg4Win/etc

    - by ericl42
    Hello, I have used Gpg4Win in the past along with FireGPG to have encryption on my emails. I am needing to roll this out to quite a few more people and was wondering if anyone else had some products they preferred better. The criteria I need is free and as user friendly as possible. I looked at MailCloak but I have had some issues with it on 1 of the 2 computers I've been testing on. It seems like it might work pretty well as a overall solution but on my computer I keep getting "Identity cannot be created." and not sure whats going on with that. Thanks for the info.

  • Big level objects collision system for 2d game

    - by Aristarhys
    I read many variants today and get some knowledge in general, so here is a steps of mine thoughts in pictures (horrible paint.net ones). We need to develop grid system, so we check only thing near, perform simple check to cut out deep check, and at - last deep check like per-pixel collision check. Step 1 - Let p1, p2 are some sprites lets first just check with circle collision - because large distance between p1, p2 this fails and of course so we don't need test more deeply. But if we have not 2, but 20 objects, why we need to even circle test something so far outside of our view. Step 2 - Add basic column system, now we don't bother with p2 if it's in a column far from p1 column, so we even don't do circle test. But p3 is in the same col, so let do circle test, which of course will fail. Step 3 - Lets improve column system to the grid system with grid cell size just like p1, p2, p3 collision boxes, so we cut out things much top or below p1. And this is all great until comes BIG OBJs which is some kind of platforms. They are much bigger then grid cell. Circle test for will be successful, but deep check for whole big obj will fail And that the part I can't get. How do I store the grid position of big object? Like 4 grid coords for big object vertexes? And if one of them close to p1 do circle check for centre of big object then a deep one if succeed? Am I do it wrong? My possible solution:

  • Question about a simple design problem

    - by Uri
    At work I stumbled uppon a method. It made a query, and returned a String based on the result of the query, such as de ID of a customer. If the query didn't return a single customer, it'd return a null. Otherwise, it'd return a String with the ID's of them. It looked like this: String error = getOwners(); if (error != null) { throw new Exception("Can't delete, the flat is owned by: " + error); } ... Ignoring the fact that getCustomers() returns a null when it should instead return an empty String, two things are happening here. It checks if the flat is owned by someone, and then returns them. I think a more readable logic would be to do this: if (isOwned) { throw new Exception("Can't delete, the flat is owned by: " + getOwners()); } ... The problem is that the first way does with one query what I do with two queries to the database. What would be a good solution involving good design and efficiency for this?

  • Query something and return the reason if nothing has been found

    - by Daniel Hilgarth
    Assume I have a Query - as in CQS that is supposed to return a single value. Let's assume that the case that no value is found is not exceptional, so no exception will be thrown in this case. Instead, null is returned. However, if no value has been found, I need to act according to the reason why no value has been found. Assuming that the Query knows the reason, how would I communicate it to the caller of the Query? A simple solution would be not return the value directly but a container object that contains the value and the reason: public class QueryResult { public TValue Value { get; private set; } public TReason ReasonForNoValue { get; private set; } } But that feels clumsy, because if a value is found, ReasonForNoValue makes no sense and if no value has been found, Value makes no sense. What other options do I have to communicate the reason? What do you think of one event per reason? For reference: This is going to be implemented in C#.

  • Moving while doing loop animation in RPGMaker

    - by AzDesign
    I made a custom class to display character portrait in RPGMaker XP Here is the class : class Poser attr_accessor :images def initialize @images = Sprite.new @images.bitmap = RPG::Cache.picture('Character.png') #100x300 @images.x = 540 #place it on the bottom right corner of the screen @images.y = 180 end end Create an event on the map to create an instance as global variable, tada! image popped out. Ok nice. But Im not satisfied, Now I want it to have bobbing-head animation-like (just like when we breathe, sometimes bob our head up and down) so I added another method : def move(x,y) @images.x += x @images.y += y end def animate(x,y,step,delay) forward = true 2.times { step.times { wait(delay) if forward move(x/step,y/step) else move(-x/step,-y/step) end } wait(delay*3) forward = false } end def wait(time) while time > 0 time -= 1 Graphics.update end end I called the method to run the animation and it works, so far so good, but the problem is, WHILE the portrait goes up and down, I cannot move my character until the animation is finished. So that's it, I'm stuck in the loop block, what I want is to watch the portrait moving up and down while I walk around village, talk to npc, etc. Anyone can solve my problem ? Or better solution ? Thanks in advance

  • Ubuntu 12.04 LTS - Apple iPad 3 (iOS 7 non-jailbroken) USB connection problem

  • FreeBSD's VPN & Mac OS X IPSecuritas

    - by alexus
    I need to be able to VPN in to my FreeBSD server from my Mac using IPSecuritas. I was wondering if anyone ever done something, I'm reading VPN over IPsec but that mainly covers if you had 2 nodes with 2 public IP address. My endpoint in IPSecuritas configured with MODE_CFG enabled so it'll have the other node to query my address from it's coming from. SSH is out of question, this is not a VPN solution, people who'd end up using VPN wouldn't know what to do, so I need very simple VPN the one that you get to use almost anywhere, you have a client and you have server, client makes a connection to server and boom, you in...

  • Virtualbox fullscreen mode problem

    - by AtharvaI
    hi all I have a slightly weird issue with virtualbox. My host OS is Win7 (64-bit) and guest OS is Ubuntu 10.10(64-bit). When I switch to fullscreen mode in virtualbox, ubuntu display resizes to fit my screen size. however, after that the display is not updated. So if i click a menu or something I don't see it appear. but it seems to work in the background. if i click a menu in fullscreen mode, i don't see anything happen, but if then switch to windowed mode I see the menu already open. I have installed virtuabox guest additions. if any has a similar issue or has found a solution please let me know thanks.

  • How do I access an Ubuntu VirtualBox guest at a static IP from an OS X host?

    - by David Siegel
    How does one configure an Ubuntu guest to use a static IP that's visible to an OS X host, and ensure that the static IP is independent of the host's network configuration? I previously used bridged networking for my guest, but I'm constantly moving my host between networks so the guest IP is always different. First, I tried setting the guest network configuration to NAT and forwarding host port 1022 to guest port 22, so I could at least ssh to a fixed address (localhost:1022): $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/Protocol" "TCP" $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/GuestPort" 22 $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/HostPort" 1022 Then, $ ssh localhost -p 1022 ssh: connect to host localhost port 1022: Connection refused But this didn't work (guest has no network access with NAT and OS X refused the connection, as you can see). I'd love a general solution that would let me communicate with my guest at a fixed IP.

  • thick client migration to web based application

    - by user1151597
    This query is related to application design the technology that I should consider during migration. The Scenario: I have a C#.net Winform application which communicates with a device. One of the main feature of this application is monitoring cyclic data(rate 200ms) sent from the device to the application. The request to start the cyclic data is sent only once in the beginning and then the application starts receiving data from the device until it sends a stop request. Now this same application needs to be deployed over the web in a intranet. The application is composed of a business logic layer and a communication layer which communicates with the device through UDP ports. I am trying to look at a solution which will allow me to have a single instance of the application on the server so that the device thinks that it is connected as usual and then from the business logic layer I can manage the clients. I want to reuse the code of the business layer and the communication layer as much as possible. Please let me know if webserives/WCF/ etc what i should consider to design the migration. Thanks in advance.

  • Searching for entity awareness in 3D space algorithm and data structure

    - by Khanser
    I'm trying to do some huge AI system just for the fun and I've come to this problem. How can I let the AI entities know about each other without getting the CPU to perform redundant and costly work? Every entity has a spatial awareness zone and it has to know what's inside when it has to decide what to do. First thoughts, for every entity test if the other entities are inside the first's reach. Ok, so it was the first try and yep, that is redundant and costly. We are working with real time AI over 10000+ entities so this is not a solution. Second try, calculate some grid over the awareness zone of every entity and test whether in this zones are entities (we are working with 3D entities with float x,y,z location coordinates) testing every point in the grid with the indexed-by-coordinate entities. Well, I don't like this because is also costly, but not as the first one. Third, create some multi linked lists over the x's and y's indexed positions of the entities so when we search for an interval between x,y and z,w positions (this interval defines the square over the spatial awareness zone) over the multi linked list, we won't have 'voids'. This has the problem of finding the nearest proximity value if there isn't one at the position where we start the search. I'm not convinced with any of the ideas so I'm searching for some enlightening. Do you people have any better ideas?

  • How can I copy the output from a remote command into the local clipboard?

    - by cwd
    I use iTerm2 as my terminal client in Mac OS X. On the local system I can use pbcopy and pbpaste to transfer data between the system clipboard and the terminal, but of course this doesn't work when you're ssh'ed to another machine. Is there some way which I can take the result of a command and copy it to the clipboard automatically? Perhaps an applescript to grab the text on the iTerm windows, then get the next to last line? For instance, if I wanted to copy the current working directory: I run pwd, then use the mouse to select the text, and then press command + c. Is there any better / faster / automatic way of doing this? I'm not looking for a bulletproof solution that would work for every command (eg: might not work when there is a huge scrollback) - I'm just looking for something to make this task that I do quite often a little less tedious. Update I'm looking into using screen to do this, but I'm still not sure if it is possible.

  • Capturing BizTalk 2004 SQLAdapter failures

    - by DanBedassa
    I was recently working on a BizTalk 2004 project where I encountered an issue with capturing exceptions (inside my orchestration) occurring from an external source. Like database server down, non-existing stored procedure, …   I thought I might write-up this in case it might help someone …   To reproduce an issue, I just rename the database to something different.   The orchestration was failing at the point where I make a SQL request via a Response-Request Port. The exception handlers were bypassed but I can see a warning in the event log saying: "The adapter failed to transmit message going to send port "   After scratching my head for a while (as a newbie to BTS 2004) to find a way to catch the exceptions from the SQLAdapter in an orchestration, here is the solution I had.   ·         Put the Send and Receive shapes inside a Scope shape ·         Set the Scope’s transaction type to “Long Running” ·         Add a Catch block expecting type “System.Exception” ·         Set the “Delivery Notification” of the associated Port to “Transmitted” ·         Change the “Retry Count” of the associated port to 0 (This will make sure BizTalk will raise the exception, instead of a warning, and you can capture that) ·         Now capture and do whatever with the exception inside the Catch block

  • A fix for the design time error in MVVM Light V4.1

    - by Laurent Bugnion
    For those of you who installed V4.1 of MVVM Light and created a project for Windows Phone 8, you will have noticed an error showing up in the design surface (either in Visual Studio designer, or in Expression Blend). The error says: “Could not load type ‘System.ComponentModel.INotifyPropertyChanging’ from assembly ‘mscorlib.extensions’” with additional information about version numbers. The error is caused by an incompatibility between versions of System.Windows.Interactivity. Because this assembly is strongly named, any version incompatibility is causing the kind of error shown here (for an interesting discussion on the strong naming issue, see this thread on Codeplex). I managed to resolve the issue for Windows Phone 8 and will publish a cleaned up installer next week. In the mean time, in order to allow you to continue development, please follow the steps: Download the new DLLs zip package (MVVMLight_V4_1_25_WP8). Right click on the Zip file and select Properties from the context menu. Press the “Unblock” button (if available) and then OK. Right click again on the zip package and select “Extract all…”. Select a known location for the new DLLs. Open the MVVM Light project with the design time error in Visual Studio 2012. Open the References folder in the Solution Explorer. Select the following DLLs: GalaSoft.MvvmLight.dll, GalaSoft.MvvmLight.Extras.dll, Microsoft.Practices.ServiceLocation.dll and System.Windows.Interactivity.dll. Press “delete” and confirm to remove the DLLs from your project. Right click on References and select Add Reference from the context menu. Browse to the folder with the new DLLs. Select the four new DLLs and press OK. Rebuild your application, and open it again in Blend or in the Visual Studio designer. The error should be gone now. In the next few days, as time allows, I will publish a new MSI containing a fixed version of the DLLs as well as a few other improvements. This quick fix should however allow you to continue working on your Windows Phone 8 projects in design mode too.   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • SharePoint Development: Making that application pool recycle less annoying

    - by Sahil Malik
    SharePoint 2010 Training: more information If you’re like me, you’re easily distracted. What was I talking about again? Oh yes! See, whenever I am writing a farm solution that requires an application pool recycle, I hit CTRL_SHIFT_B to deploy (how to remap CTRL_SHIFT_B to deploy?).Now, I have what, a good 15-20 seconds to goof off and check my gmail/facebook/twitter/IM conversations, right? Sure .. 30 minutes later .. my application pool has died and recycled 3 times on it’s own. Hmm. Clearly, this was becoming a serious issue. So what am I supposed to do here? Well, worry not! Here is what you need to do, Right click\Properties on your SharePoint project, and look for the “SharePoint” tab. Look for post-deployment command line, and add the following post-deployment command line. (Be careful, copy paste exactly as is).   Read full article ....

  • What is the fastest CPU my laptop can support?

    - by Dave
    I have a Dell Latitude D830 laptop and would like to speed up compile times on it. I have confirmed that it is, indeed, the processor time that is the bottleneck. How can I tell what processors are compatible with the motherboard to pick the best available? I run dual boot Ubuntu Maverick and Windows 7. lshw tells me that my motherboard is OHN338 from Dell, Inc. If anyone has a generic solution, i.e. "For motherboard X, here is how you find out what processors are supported," that would be make this question much more useful to future visitors. But if you also know of a way to find out specific to my model, that would be great as well.

  • Encrypt shared files on AD Domain.

    - by Walter
    Can I encrypt shared files on windows server and allow only authenticated domain users have access to these files? The scenario as follows: I have a software development company, and I would like to protect my source code from being copied by my programmers. One problem is that some programmers use their own laptops to developing the company's software. In this scenario it's impossible to prevent developers from copying the source code for their laptops. In this case I thought about the following solution, but i don't know if it's possible to implement. The idea is to encrypt the source code and they are accessible (decrypted) only when developers are logged into the AD domain, ie if they are not logged into the AD domain, the source code would be encrypted be useless. Can be implemented this ? What technology should be used?

  • Linux IPv6: DHCP and /127 prefixes

    - by Jeff Ferland
    I've tried multiple pieces of DHCP client and software in attempting to setup a solution for allocating a /127 prefix to virtual machines so that each maintains its own layer 2 isolation. Because there would only be one host assigned to each network, a /64 is impractical. While the prefix size could reasonably be somewhere in the /64-127 range, the crux of the problem has been the same regardless of the software used in configuring: the DHCP call to bring up the interface uses the address advertised by DHCPv6 and inserts two routes: the /127 given by the router advertising packets and a /64 as well. Any thoughts on why I'm getting the additional route added across dhcp client vendors?

  • Move some iTunes library items to different drive?

    - by Sören Kuklau
    My internal hard drive is somewhat small, and I only regularly listen to a fraction of my iTunes library anyway, so I'd like to keep large portions on it on an external drive for archival purposes. Since dealing with multiple iTunes libraries is somewhat painful, the solution I'm looking for is to move individual items of the library to a different location, without compromising the "Keep organized" and "Copy files" settings. I found an AppleScript that I assume is supposed to do this, Move Files To Folder…, but it instead copies them, and doesn't update the library accordingly. I can do this manually by moving the file, then accessing it in iTunes — it'll prompt me for the new location. I just don't intend to do this one by one for thousands of files.

  • Wrong resolution for Lightdm/GDM on Ubuntu 13.04 using HDMI

    - by f03lipe
    I've tried all the solution I could find on the matter so far, but the error persists. My problem is that the login screen (both under gdm and lightdm) runs with the wrong resolution, even though all is fine when I log in. The error occurs solely when I have my HDMI cable connected to my other screen. The login screen resolution becomes 1024x768 (for my 1366x768 laptop screen) and mirrored on my screen, which is 1920x1080. I've had this issue on version 12.04 (the last one before I upgraded to 13.04), but I got it fixed by adding the xrandr commands on the begining of the /etc/gdm/Init/Default file. This doesn't seem to work anymore. I've also tried telling lightdm to run a script fixing the resolution with xrandr (by editing /etc/lightdm/lightdm.conf), but lightdm crashes, and I'm forced to log in with low graphic settigs. Hint: when ubuntu is loading, the resolution starts OK, then goes bad right before the login screen is initialized. Does that mean that there's nothing wrong with my graphic cards? What do you think? Cheers!

  • Optimal way to make MySQL backups for fairly large databases (MyISAM / InnoDB)

    - by WinkyWolly
    Currently we have one beefy MySQL database that runs a couple of high traffic Django based websites as well as some e-commerce websites of decent size. As a result we have a fair amount of large databases using both InnoDB and MyISAM tables. Unfortunately we've recently hit a wall due to the amount of traffic so I've setup another master server to help alleviate reads / backups. Now at the moment I simply use mysqldump with a few arguments and it's proven to be fine.. until now. Obviously mysqldump is a slow quick method however I believe we've outgrown its use. I now need a good alternative and have been looking into utilizing Maatkits mk-parallel-dump utility or an LVM snapshot solution. Succinct short version: I have a fairly large MySQL databases I need to backup Current method using mysqldump is inefficient and slow (causing issues) Looking into something such as mk-parallel-dump or LVM snapshots Any recommendations or ideas would be appreciated - since I have to re-do how we're doing things I rather have it done properly / most efficient :).

  • How to convince a client to switch to a framework *now*; also examples of great, large-scale php applications.

    - by cbrandolino
    Hi everybody. I'm about to start working on a very ambitious project that, in my opinion, has some great potential for what concerns the basic concept and the implementation ideas (implementation as in how this ideas will be implemented, not as in programming). The state of the code right now is unluckily subpar. It's vanilla php, no framework, no separation between application and visualization logic. It's been done mostly by amateur students (I know great amateur/student programmers, don't get me wrong: this was not the case though). The clients are really great, and they know the system won't scale and needs a redesign. The problem is, they would like to launch a beta ASAP and then think of rebuilding. Since just the basic functionalities are present now, I suggested it would be a great idea if we (we're a three-people shop, all very proficient) ported that code to some framework (we like CodeIgniter) before launching. We would reasonably be able to do that in < 10 days. Problem is, they don't think php would be a valid long-term solution anyway, so they would prefer to just let it be and fix the bugs for now (there's quite a bit) and then directly switch to some ruby/python based system. Porting to CI now will make future improvements incredibly easier, the current code more secure, changing the style - still being discussed with the designers - a breeze (reminder: there are database calls in template files right now); the biggest obstacle is the lack of trust in php as a valid, scalable technology. So well, I need some examples of great php applications (apart from facebook) and some suggestions on how to try to convince them to port soon. Again, they're great people - it's not like they would like ruby cause it's so hot right now; they just don't trust php since us cool programmers like bashing it, I suppose, but I'm sure going on like this for even one more day would be a mistake. Also, we have some weight in the decision process.

  • Behaviour of nginx as proxy

    - by HD
    I'm testing nginx with different configurations to replace an architecture working with squid + apache. I know that I can use nginx to manage static requests and load balancing but I'm interested in one particular solution that I don't understand clearly: I'm using 2 nginx servers (balanced) with the proxy_pass setting to pass all requests to an apache server. When one client makes a request to the site one of the nginx servers process it and send it to the apache server. Now, how this behaviour could be an improvement to my system?, it seems that all requests are passing through apache and I don't see benefit at all. What happens when 100 simultaneous connections pass through nginx? The 100 connections will be going to the apache server or is some kind of internal behaviour that allows an small impact into apache?
