• Why use 3d matrix and camera in 2D world for 2d geometric figures?

  - by Navy Seal

  I'm working in XNA on a 2d isometric world/game and I'm using DrawUserPrimitives to draw some geometric figures... I saw some tutorials about creating dynamic shadows but I didn't understood why they use a "3d" matrix to control the transformations since the figure I'm drawing is in 2d perspective. I know I'm drawing a 2d figure in 3d but I still can't understand if I really need to work with the matrix. Is there any advantage in using a 3d Matrix to control camera and view? Any reason why I can't just update my vertex's positions by using a regular method since the view is always the same... And since I want to work only with single figures, won't this cause all the geometric figures have the same transformations simultaneously? To understand better what I mean here's a video http://www.youtube.com/watch?v=LjvsGHXaGEA&feature=player_embedded

• IPTV World Forum : vingt décodeurs TV fondés sur Qt illustrent les différentes facettes du framework (déclaratif, Web, widgets)

  Aujourd'hui se tient l'un des plus grands événements sur la télévision, l'IPTV World Forum, où un total de vingt sociétés exposent leurs décodeurs basés sur Qt (STB, pour Set-Top Box). Qt y est mis à l'oeuvre à toutes les sauces : de plus en plus de fabricants prévoient d'utiliser Qt Quick pour préparer des interfaces innovantes ; d'un autre côté, les télécoms et opérateurs de télévision numériques préfèrent les interfaces HTML5 avec Qt WebKit (cela sans compter ceux qui utilisent les interfaces plus classiques en C++). Trois ans auparavant, les sociétés utilisant Qt étaient rares à ce forum ; aujourd'hui, il est dur d'en trouver ne l'utilisant pas. On va passer en revue quelques utilisateurs de Qt. htt...

• Introducing Task-It. A real-world application using RadControls for Silverlight 4

  This is the first in a series of blog posts based around an application called Task-It that I have developed in Silverlight 4. Task-It is real-world application designed for people that need a simple way to manage the numerous tasks that we all strive to accomplish on a daily basis. Figure 1: Task-It Tasks page Figure 2: Task-It Dashboard page I have developed this application for several reasons: There are many task management applications out there, and I have used quite a few of them, but I havent found one that really grabbed me. Many of these applications had their strong points,but some were overly complex, some lacked key features, some cost too much money, and so forth. I thought it would be nice to identify the best parts of each, and take my stab at building my own. During my evaluation of task management applications, I have not yet ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How can I simulate a rigid body bounced from a wall in 3D world?

  - by HyperGroups

  How can I simulate a rigid sword bounced from a wall and hit the ground (like in physical world)? I want to use this for a simple animation. I can detect the figure and the size of the sword (maybe needed in doing bounce). Rotation can be controlled by quaternions/matrix/euler angles. It should turn the head and do rotations and fly to the ground. How can I simulate this physical process? Maybe what I need is an equation and some parameters? I need these data, and would combine them into my movie file, I use Mathematica to do the thing that generate the movie file(If I have the data, I can also export it into a 3DSMax script for example).

• How do I create a big multiplayer world in UDK?

  - by Dorpe

  I want to create a big multiplayer world in UDK and I'm having a few difficulties. I created the biggest terrain possible but then any terrain related action I do takes forever. However, I've seen videos of people make same size terrain and working without a problem. My pc is strong enough, so maybe someone can tell me what I'm doing wrong. I want to make it even bigger then the biggest terrain size, so I was thinking of doing level streaming but then I read that streaming is working server side which means if I have a player on every terrain all terrains will still be loaded and I want to save as much memory possible so it will work well online. Thanks for any help you can give.

• Enterprise Process Maps: A Process Picture worth a Million Words

  - by raul.goycoolea

  p { margin-bottom: 0.08in; }h1 { margin-top: 0.33in; margin-bottom: 0in; color: rgb(54, 95, 145); page-break-inside: avoid; }h1.western { font-family: "Cambria",serif; font-size: 14pt; }h1.cjk { font-family: "DejaVu Sans"; font-size: 14pt; }h1.ctl { font-size: 14pt; } Getting Started with Business Transformations A well-known proverb states that "A picture is worth a thousand words." In relation to Business Process Management (BPM), a credible analyst might have a few questions. What if the picture was taken from some particular angle, like directly overhead? What if it was taken from only an inch away or a mile away? What if the photographer did not focus the camera correctly? Does the value of the picture depend on who is looking at it? Enterprise Process Maps are analogous in this sense of relative value. Every BPM project (holistic BPM kick-off, enterprise system implementation, Service-oriented Architecture, business process transformation, corporate performance management, etc.) should be begin with a clear understanding of the business environment, from the biggest picture representations down to the lowest level required or desired for the particular project type, scope and objectives. The Enterprise Process Map serves as an entry point for the process architecture and is defined: the single highest level of process mapping for an organization. It is constructed and evaluated during the Strategy Phase of the Business Process Management Lifecycle. (see Figure 1) Fig. 1: Business Process Management Lifecycle Many organizations view such maps as visual abstractions, constructed for the single purpose of process categorization. This, in turn, results in a lesser focus on the inherent intricacies of the Enterprise Process view, which are explored in the course of this paper. With the main focus of a large scale process documentation effort usually underlying an ERP or other system implementation, it is common for the work to be driven by the desire to "get to the details," and to the type of modeling that will derive near-term tangible results. For instance, a project in American Pharmaceutical Company X is driven by the Director of IT. With 120+ systems in place, and a lack of standardized processes across the United States, he and the VP of IT have decided to embark on a long-term ERP implementation. At the forethought of both are questions, such as: How does my application architecture map to the business? What are each application's functionalities, and where do the business processes utilize them? Where can we retire legacy systems? Well-developed BPM methodologies prescribe numerous model types to capture such information and allow for thorough analysis in these areas. Process to application maps, Event Driven Process Chains, etc. provide this level of detail and facilitate the completion of such project-specific questions. These models and such analysis are appropriately carried out at a relatively low level of process detail. (see figure 2) Fig. 2: The Level Concept, Generic Process HierarchySome of the questions remaining are ones of documentation longevity, the continuation of BPM practice in the organization, process governance and ownership, process transparency and clarity in business process objectives and strategy. The Level Concept in Brief Figure 2 shows a generic, four-level process hierarchy depicting the breakdown of a "Process Area" into progressively more detailed process classifications. The number of levels and the names of these levels are flexible, and can be fit to the standards of the organization's chosen terminology or any other chosen reference model that makes logical sense for both short and long term process description. It is at Level 1 (in this case the Process Area level), that the Enterprise Process Map is created. This map and its contained objects become the foundation for a top-down approach to subsequent mapping, object relationship development, and analysis of the organization's processes and its supporting infrastructure. Additionally, this picture serves as a communication device, at an executive level, describing the design of the business in its service to a customer. It seems, then, imperative that the process development effort, and this map, start off on the right foot. Figuring out just what that right foot is, however, is critical and trend-setting in an evolving organization. Key Considerations Enterprise Process Maps are usually not as living and breathing as other process maps. Just as it would be an extremely difficult task to change the foundation of the Sears Tower or a city plan for the entire city of Chicago, the Enterprise Process view of an organization usually remains unchanged once developed (unless, of course, an organization is at a stage where it is capable of true, high-level process innovation). Regardless, the Enterprise Process map is a key first step, and one that must be taken in a precise way. What makes this groundwork solid depends on not only the materials used to construct it (process areas), but also the layout plan and knowledge base of what will be built (the entire process architecture). It seems reasonable that care and consideration are required to create this critical high level map... but what are the important factors? Does the process modeler need to worry about how many process areas there are? About who is looking at it? Should he only use the color pink because it's his boss' favorite color? Interestingly, and perhaps surprisingly, these are all valid considerations that may just require a bit of structure. Below are Three Key Factors to consider when building an Enterprise Process Map: Company Strategic Focus Process Categorization: Customer is Core End-to-end versus Functional Processes Company Strategic Focus As mentioned above, the Enterprise Process Map is created during the Strategy Phase of the Business Process Management Lifecycle. From Oracle Business Process Management methodology for business transformation, it is apparent that business processes exist for the purpose of achieving the strategic objectives of an organization. In a prescribed, top-down approach to process development, it must be ensured that each process fulfills its objectives, and in an aggregated manner, drives fulfillment of the strategic objectives of the company, whether for particular business segments or in a broader sense. This is a crucial point, as the strategic messages of the company must therefore resound in its process maps, in particular one that spans the processes of the complete business: the Enterprise Process Map. One simple example from Company X is shown below (see figure 3). Fig. 3: Company X Enterprise Process Map In reviewing Company X's Enterprise Process Map, one can immediately begin to understand the general strategic mindset of the organization. It shows that Company X is focused on its customers, defining 10 of its process areas belonging to customer-focused categories. Additionally, the organization views these end-customer-oriented process areas as part of customer-fulfilling value chains, while support process areas do not provide as much contiguous value. However, by including both support and strategic process categorizations, it becomes apparent that all processes are considered vital to the success of the customer-oriented focus processes. Below is an example from Company Y (see figure 4). Fig. 4: Company Y Enterprise Process Map Company Y, although also a customer-oriented company, sends a differently focused message with its depiction of the Enterprise Process Map. Along the top of the map is the company's product tree, overarching the process areas, which when executed deliver the products themselves. This indicates one strategic objective of excellence in product quality. Additionally, the view represents a less linear value chain, with strong overlaps of the various process areas. Marketing and quality management are seen as a key support processes, as they span the process lifecycle. Often, companies may incorporate graphics, logos and symbols representing customers and suppliers, and other objects to truly send the strategic message to the business. Other times, Enterprise Process Maps may show high level of responsibility to organizational units, or the application types that support the process areas. It is possible that hundreds of formats and focuses can be applied to an Enterprise Process Map. What is of vital importance, however, is which formats and focuses are chosen to truly represent the direction of the company, and serve as a driver for focusing the business on the strategic objectives set forth in that right. Process Categorization: Customer is Core In the previous two examples, processes were grouped using differing categories and techniques. Company X showed one support and three customer process categorizations using encompassing chevron objects; Customer Y achieved a less distinct categorization using a gradual color scheme. Either way, and in general, modeling of the process areas becomes even more valuable and easily understood within the context of business categorization, be it strategic or otherwise. But how one categorizes their processes is typically more complex than simply choosing object shapes and colors. Previously, it was stated that the ideal is a prescribed top-down approach to developing processes, to make certain linkages all the way back up to corporate strategy. But what about external influences? What forces push and pull corporate strategy? Industry maturity, product lifecycle, market profitability, competition, etc. can all drive the critical success factors of a particular business segment, or the company as a whole, in addition to previous corporate strategy. This may seem to be turning into a discussion of theory, but that is far from the case. In fact, in years of recent study and evolution of the way businesses operate, cross-industry and across the globe, one invariable has surfaced with such strength to make it undeniable in the game plan of any strategy fit for survival. That constant is the customer. Many of a company's critical success factors, in any business segment, relate to the customer: customer retention, satisfaction, loyalty, etc. Businesses serve customers, and so do a business's processes, mapped or unmapped. The most effective way to categorize processes is in a manner that visualizes convergence to what is core for a company. It is the value chain, beginning with the customer in mind, and ending with the fulfillment of that customer, that becomes the core or the centerpiece of the Enterprise Process Map. (See figure 5) Fig. 5: Company Z Enterprise Process Map Company Z has what may be viewed as several different perspectives or "cuts" baked into their Enterprise Process Map. It has divided its processes into three main categories (top, middle, and bottom) of Management Processes, the Core Value Chain and Supporting Processes. The Core category begins with Corporate Marketing (which contains the activities of beginning to engage customers) and ends with Customer Service Management. Within the value chain, this company has divided into the focus areas of their two primary business lines, Foods and Beverages. Does this mean that areas, such as Strategy, Information Management or Project Management are not as important as those in the Core category? No! In some cases, though, depending on the organization's understanding of high-level BPM concepts, use of category names, such as "Core," "Management" or "Support," can be a touchy subject. What is important to understand, is that no matter the nomenclature chosen, the Core processes are those that drive directly to customer value, Support processes are those which make the Core processes possible to execute, and Management Processes are those which steer and influence the Core. Some common terms for these three basic categorizations are Core, Customer Fulfillment, Customer Relationship Management, Governing, Controlling, Enabling, Support, etc. End-to-end versus Functional Processes Every high and low level of process: function, task, activity, process/work step (whatever an organization calls it), should add value to the flow of business in an organization. Suppose that within the process "Deliver package," there is a documented task titled "Stop for ice cream." It doesn't take a process expert to deduce the room for improvement. Though stopping for ice cream may create gain for the one person performing it, it likely benefits neither the organization nor, more importantly, the customer. In most cases, "Stop for ice cream" wouldn't make it past the first pass of To-Be process development. What would make the cut, however, would be a flow of tasks that, each having their own value add, build up to greater and greater levels of process objective. In this case, those tasks would combine to achieve a status of "package delivered." Figure 3 shows a simple example: Just as the package can only be delivered (outcome of the process) without first being retrieved, loaded, and the travel destination reached (outcomes of the process steps), some higher level of process "Play Practical Joke" (e.g., main process or process area) cannot be completed until a package is delivered. It seems that isolated or functionally separated processes, such as "Deliver Package" (shown in Figure 6), are necessary, but are always part of a bigger value chain. Each of these individual processes must be analyzed within the context of that value chain in order to ensure successful end-to-end process performance. For example, this company's "Create Joke Package" process could be operating flawlessly and efficiently, but if a joke is never developed, it cannot be created, so the end-to-end process breaks. Fig. 6: End to End Process Construction That being recognized, it is clear that processes must be viewed as end-to-end, customer-to-customer, and in the context of company strategy. But as can also be seen from the previous example, these vital end-to-end processes cannot be built without the functionally oriented building blocks. Without one, the other cannot be had, or at least not in a complete and organized fashion. As it turns out, but not discussed in depth here, the process modeling effort, BPM organizational development, and comprehensive coverage cannot be fully realized without a semi-functional, process-oriented approach. Then, an Enterprise Process Map should be concerned with both views, the building blocks, and access points to the business-critical end-to-end processes, which they construct. Without the functional building blocks, all streams of work needed for any business transformation would be lost mess of process disorganization. End-to-end views are essential for utilization in optimization in context, understanding customer impacts, base-lining all project phases and aligning objectives. Including both views on an Enterprise Process Map allows management to understand the functional orientation of the company's processes, while still providing access to end-to-end processes, which are most valuable to them. (See figures 7 and 8). Fig. 7: Simplified Enterprise Process Map with end-to-end Access Point The above examples show two unique ways to achieve a successful Enterprise Process Map. The first example is a simple map that shows a high level set of process areas and a separate section with the end-to-end processes of concern for the organization. This particular map is filtered to show just one vital end-to-end process for a project-specific focus. Fig. 8: Detailed Enterprise Process Map showing connected Functional Processes The second example shows a more complex arrangement and categorization of functional processes (the names of each process area has been removed). The end-to-end perspective is achieved at this level through the connections (interfaces at lower levels) between these functional process areas. An important point to note is that the organization of these two views of the Enterprise Process Map is dependent, in large part, on the orientation of its audience, and the complexity of the landscape at the highest level. If both are not apparent, the Enterprise Process Map is missing an opportunity to serve as a holistic, high-level view. Conclusion In the world of BPM, and specifically regarding Enterprise Process Maps, a picture can be worth as many words as the thought and effort that is put into it. Enterprise Process Maps alone cannot change an organization, but they serve more purposes than initially meet the eye, and therefore must be designed in a way that enables a BPM mindset, business process understanding and business transformation efforts. Every Enterprise Process Map will and should be different when looking across organizations. Its design will be driven by company strategy, a level of customer focus, and functional versus end-to-end orientations. This high-level description of the considerations of the Enterprise Process Maps is not a prescriptive "how to" guide. However, a company attempting to create one may not have the practical BPM experience to truly explore its options or impacts to the coming work of business process transformation. The biggest takeaway is that process modeling, at all levels, is a science and an art, and art is open to interpretation. It is critical that the modeler of the highest level of process mapping be a cognoscente of the message he is delivering and the factors at hand. Without sufficient focus on the design of the Enterprise Process Map, an entire BPM effort may suffer. For additional information please check: Oracle Business Process Management.

  I have an unmanaged linux vps Ubuntu 11.10 (Oneiric Ocelot). I have LNMP installed. Also php-fpm php-apc, varnish, memcache. I have (or rather had) several live sites on it. under normal load the server uses ~700 mb memory.

• postfix with mailman

  - by Thufir

  What should happen is that [email protected] should be delivered to that users inbox on localhost, user@localhost. Thunderbird works fine at reading user@localhost. I'm just using a small portion of postfix-dovecot with Ubuntu mailman. How can I get postfix to recognize the FQDN and deliver them to a localhost inbox? root@dur:~# root@dur:~# tail /var/log/mail.err;tail /var/log/mailman/subscribe;postconf -n Aug 27 18:59:16 dur dovecot: lda(root): Error: chdir(/root) failed: Permission denied Aug 27 18:59:16 dur dovecot: lda(root): Error: user root: Initialization failed: Initializing mail storage from mail_location setting failed: stat(/root/Maildir) failed: Permission denied (euid=65534(nobody) egid=65534(nogroup) missing +x perm: /root, dir owned by 0:0 mode=0700) Aug 27 18:59:16 dur dovecot: lda(root): Fatal: Invalid user settings.

• Windows 2003 print services for unix causing CUPS "lpd_command returning 1"

  We have several Windows 2003 servers with print services for Unix on them, and which allow Linux machines running CUPS to use printers defined to CUPS with the URI lpd://printer_server/printer_queue_name - they work. An attempt to provide different printers on a different Windows 2003 server with print services for Unix newly enabled causes CUPS to behave like this: a newly defined printer will be in state "Idle". An attempt to print causes CUPS to change the printer state to "Disabled". In /var/log/cups/error_log, the relevant messages appear to be D [01/Dec/2012:06:14:18 -0800] [Job 16] lpd_command 02 hp775cm_ps D [01/Dec/2012:06:14:18 -0800] [Job 16] Sending command string (16 bytes)... D [01/Dec/2012:06:14:18 -0800] [Job 16] Reading command status... D [01/Dec/2012:06:14:18 -0800] [Job 16] lpd_command returning 1 E [01/Dec/2012:06:14:18 -0800] PID 18786 stopped with status 1! Since my Linux boxes can print to other printers via other Windows 2003 print spoolers, I'm wondering what obscure Windows component could be causing this. I don't think it is Windows firewall, since nmap sees the lpd port (515) open on the server. telnet to the server at port 515 declares Connected to server.internal.example.com (10.22.33.44). Escape character is '^]' Connection closed by foreign host. Windows clients successfully print to the CIFS/SMB share of the hp755cm_ps printer. What other reasons are there for Windows to refuse an lpd request?

• Lync CMS replication is failing for all Domain Computers

  - by Ravi Kanneganti

  I have Lync Server 2010 and Active Directory installed on 2 different Windows Server 2008 R2 machines. I have added a Windows 7 PC to AD. And I have added this computer to Trusted Application Servers Pool and published the topology. I want to build an UCMA application to extend Lync Server functionality. I have installed UCMA 3.0 SDK in the same computer where Lync Server is residing. But, CMS Replication isn't happening and "Get-CsManagementStoreReplicationStatus" always gives Uptodate as "False" for my Windows 7 PC. I have even tried "Invoke-CSManagementStoreReplication" but nothing changed. Also, this is the error message that I can see in the log file: TL_WARN(TF_COMPONENT) [2]0500.07B8::04/05/2012-14:55:07.296.00000f85 (XDS_Replica_Replicator,FileDistributeTask.Execute:filedistributetask.cs(165))(000000000043B3FA)**Could not distribute the file.

• VSFTPD does not allow upload with virtual users

  - by Mr. Squig

  I am attempting to setup VSFTPD with virtual users on a server running Ubuntu 12.04. I have configured the server to allow for virtual users to login, but I am having trouble getting it to allow uploads. My vsftpd.conf is as follows: listen=YES anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 anon_upload_enable=YES dirmessage_enable=YES use_localtime=YES xferlog_enable=YES connect_from_port_20=YES chroot_local_user=YES virtual_use_local_privs=YES guest_enable=YES guest_username=virtual user_sub_token=$USER local_root=/var/www/$USER hide_ids=YES secure_chroot_dir=/var/run/vsftpd/empty pam_service_name=vsftpd rsa_cert_file=/etc/ssl/private/vsftpd.pem /etc/pam.d/vsftpd contains: auth required pam_pwdfile.so pwdfile /etc/vsftpd.passwd crypt=hash account required pam_permit.so crypt=hash I have two virtual users set up, one of which has the same name as a local user. They each have a directory in /var/www/ owned by 'virtual'. As I understand it, when a virtual user logs in this way they will appear to the system as the user virtual. Using this configuration user can log on, but cannot upload files. The error given in /var/log/vsftpd.log is: Tue Nov 20 19:49:00 2012 [pid 2] CONNECT: Client "96.233.116.53" Tue Nov 20 19:49:07 2012 [pid 1] [zac] OK LOGIN: Client "96.233.116.53" Tue Nov 20 19:49:11 2012 [pid 2] CONNECT: Client "96.233.116.53" Tue Nov 20 19:49:11 2012 [pid 1] [zac] OK LOGIN: Client "96.233.116.53" Tue Nov 20 19:49:11 2012 [pid 3] [zac] FAIL CHMOD: Client "96.233.116.53", "/test.ppm 644" I have tried changing the permissions of these directories in all sorts of ways, but nothing seem to work. I have a feeling that it is something simple related to permissions. Any ideas?

Example: curl -i http://example.com/api/call1/ Expected result: HTTP/1.1 200 OK Accept-Ranges: bytes Content-Type: application/json Date: Fri, 13 Apr 2012 23:48:21 GMT Last-Modified: Fri, 13 Apr 2012 22:58:56 GMT Server: nginx X-UA-Compatible: IE=Edge,chrome=1 Content-Length: 38 Connection: keep-alive {"logout": true} Here's what I have so far in my nginx conf: location ~ ^/api/(.*)$ { index /api_logout.json; alias /path/to/file/api_logout.json; types { } default_type "application/json; charset=utf-8"; break; } However, when I try to make the request the Content-Type doesn't stick: $ curl -i http://example.com/api/call1/ HTTP/1.1 200 OK Accept-Ranges: bytes Content-Type: application/octet-stream Date: Fri, 13 Apr 2012 23:48:21 GMT Last-Modified: Fri, 13 Apr 2012 22:58:56 GMT Server: nginx X-UA-Compatible: IE=Edge,chrome=1 Content-Length: 38 Connection: keep-alive {"logout": true} Is there a better way to do this? How can I get the application/json type to stick?

• Apache reverse proxy: no protocol handler

  - by gonvaled

  I am trying to configure a reverse proxy with apache, but I am getting a No protocol handler was valid for the URL error, which I do not understand. This is the relevant configuration of apache: ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /gonvaled/examples/jsonrpc/output/services/ http://localhost:8000/services/ ProxyPassReverse /gonvaled/examples/jsonrpc/output/services/ http://localhost:8000/services/ The requests is reaching apache as: POST /gonvaled/examples/jsonrpc/output/services/EchoService.py HTTP/1.1 And they should be forwarded to my internal service, located at: 0.0.0.0:8000/services/EchoService.py These are the logs: ==> /var/log/apache2/error.log <== [Wed Jun 20 02:05:20 2012] [debug] proxy_util.c(1506): [client 127.0.0.1] proxy: http: found worker http://localhost:8000/services/ for http://localhost:8000/services/EchoService.py, referer: http://localhost/gonvaled/examples/jsonrpc/output/JSONRPCExample.safari.cache.html [Wed Jun 20 02:05:20 2012] [debug] mod_proxy.c(998): Running scheme http handler (attempt 0) [Wed Jun 20 02:05:20 2012] [warn] proxy: No protocol handler was valid for the URL /gonvaled/examples/jsonrpc/output/services/EchoService.py.

• Remapping Home/End from PC to Mac Via Synergy is not client specific.

  - by DtBeloBrown

  This question asks about the end key but the answers give no examples: http://superuser.com/questions/60052/what-key-works-like-end-using-a-mac-with-synergy If they had, I am guessing that they would likely have run into this problem. Adding lines like the bottom two of this: section: options keystroke(End) = keystroke(Control+Right,myiMac) keystroke(Home) = keystroke(Control+Left,myiMac) to my synergy.sgc in MyDocuments on the winXP machine would work but causes the keys to stop functioning on the winXP machine. Unacceptable. I next tried a compromise: keystroke(End) = keystroke(Control+Right,myiMac); keystroke(End,myPc) keystroke(Home) = keystroke(Control+Left,myiMac); keystroke(Home,myPc) Expecting that to broadcast the keystrokes to both machines regardless of which one was the Active Screen. That and many other variations did not work. What am I doing wrong? Has someone actually done this?

• php file downloads instead of being processed with ajax on apache

  - by eagleon

  I have a small website where some content is displayed within a HTML tag using AJAX. The content is simply taken from another page on the same web site. However, sometimes instead of loading the parsed PHP file, the browser displays a download box instead. I downloaded the file and this is what it looks like a text file mixed with binary or gzipped data. I can't paste the binary stuff here, but here are some of the headers: Jul 2012 18:52:16 GMT Server: Apache/2 X-Powered-By: PHP/5.3.10 Content-Encoding: gzip Vary: Accept-Encoding,User-Agent Keep-Alive: timeout=1, max=95 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: text/html HTTP/1.1 304 Not Modified Date: Sun, 01 Jul 2012 18:52:16 GMT Server: Apache/2 Connection: Keep-Alive Keep-Alive: timeout=1, max=93 ETag: "2fc857-409-4c39691c59b40" HTTP/1.1 304 Not Modified Date: Sun, 01 Jul 2012 18:52:16 GMT Server: Apache/2 Connection: Keep-Alive Keep-Alive: timeout=1, max=92 ETag: "2fc854-3e5-4c39691b65900" HTTP/1.1 304 Not Modified Date: Sun, 01 Jul 2012 18:52:16 GMT Server: Apache/2 Connection: Keep-Alive Keep-Alive: timeout=1, max=91 ETag: "2fc847-3e3-4c3969197d480" and large blocks of stuff like this: µàl]&BaËÜk#ìÏ

• Why is this class re-initialized every time?

  - by pinnacler

  I have 4 files and the code 'works' as expected. I try to clean everything up, place code into functions, etc... and everything looks fine... and it doesn't work. Can somebody please explain why MatLab is so quirky... or am I just stupid? Normally, I type terminator = simulation(100,20,0,0,0,1); terminator.animate(); and it should produce a map of trees with the terminator walking around in a forest. Everything rotates to his perspective. When I break it into functions... everything ceases to work. I really only changed a few lines of code, shown in comments. Code that works: classdef simulation properties landmarks robot end methods function obj = simulation(mapSize, trees, x,y,heading,velocity) obj.landmarks = landmarks(mapSize, trees); obj.robot = robot(x,y,heading,velocity); end function animate(obj) %Setup Plots fig=figure; xlabel('meters'), ylabel('meters') set(fig, 'name', 'Phil''s AWESOME 80''s Robot Simulator') xymax = obj.landmarks.mapSize*3; xymin = -(obj.landmarks.mapSize*3); l=scatter([0],[0],'bo'); axis([xymin xymax xymin xymax]); obj.landmarks.apparentPositions %Simulation Loop THIS WAS ORGANIZED for n = 1:720, %Calculate and Set Heading/Location obj.robot.headingChange = navigate(n); %Update Position obj.robot.heading = obj.robot.heading + obj.robot.headingChange; obj.landmarks.heading = obj.robot.heading; y = cosd(obj.robot.heading); x = sind(obj.robot.heading); obj.robot.x = obj.robot.x + (x*obj.robot.velocity); obj.robot.y = obj.robot.y + (y*obj.robot.velocity); obj.landmarks.x = obj.robot.x; obj.landmarks.y = obj.robot.y; %Animate set(l,'XData',obj.landmarks.apparentPositions(:,1),'YData',obj.landmarks.apparentPositions(:,2)); rectangle('Position',[-2,-2,4,4]); drawnow end end end end ----------- classdef landmarks properties fixedPositions %# positions in a fixed coordinate system. [ x, y ] mapSize = 10; %Map Size. Value is side of square x=0; y=0; heading=0; headingChange=0; end properties (Dependent) apparentPositions end methods function obj = landmarks(mapSize, numberOfTrees) obj.mapSize = mapSize; obj.fixedPositions = obj.mapSize * rand([numberOfTrees, 2]) .* sign(rand([numberOfTrees, 2]) - 0.5); end function apparent = get.apparentPositions(obj) %-STILL ROTATES AROUND ORIGINAL ORIGIN currentPosition = [obj.x ; obj.y]; apparent = bsxfun(@minus,(obj.fixedPositions)',currentPosition)'; apparent = ([cosd(obj.heading) -sind(obj.heading) ; sind(obj.heading) cosd(obj.heading)] * (apparent)')'; end end end ---------- classdef robot properties x y heading velocity headingChange end methods function obj = robot(x,y,heading,velocity) obj.x = x; obj.y = y; obj.heading = heading; obj.velocity = velocity; end end end ---------- function headingChange = navigate(n) %steeringChange = 5 * rand(1) * sign(rand(1) - 0.5); Most chaotic shit %Draw an S if n <270 headingChange=1; elseif n<540 headingChange=-1; elseif n<720 headingChange=1; else headingChange=1; end end Code that does not work... classdef simulation properties landmarks robot end methods function obj = simulation(mapSize, trees, x,y,heading,velocity) obj.landmarks = landmarks(mapSize, trees); obj.robot = robot(x,y,heading,velocity); end function animate(obj) %Setup Plots fig=figure; xlabel('meters'), ylabel('meters') set(fig, 'name', 'Phil''s AWESOME 80''s Robot Simulator') xymax = obj.landmarks.mapSize*3; xymin = -(obj.landmarks.mapSize*3); l=scatter([0],[0],'bo'); axis([xymin xymax xymin xymax]); obj.landmarks.apparentPositions %Simulation Loop for n = 1:720, %Calculate and Set Heading/Location %Update Position headingChange = navigate(n); obj.robot.updatePosition(headingChange); obj.landmarks.updatePerspective(obj.robot.heading, obj.robot.x, obj.robot.y); %Animate set(l,'XData',obj.landmarks.apparentPositions(:,1),'YData',obj.landmarks.apparentPositions(:,2)); rectangle('Position',[-2,-2,4,4]); drawnow end end end end ----------------- classdef landmarks properties fixedPositions; %# positions in a fixed coordinate system.

I would appreciate any help as to why things aren't working. All I did was take the code from the first section from under comment: %Simulation Loop THIS WAS ORGANIZED and break it into 2 functions. One in robot and one in landmarks. Is a new instance created every time because it's constantly printing the same heading for this line int he robot class obj.heading = obj.heading + headingChange;

• php soapclient responds as 'null' but xml response is ok using __getLastResponse

  - by Roger S

  I'm looking for help with a php soapclient call: The call is to a remote panel and I want to pull off the log data. There are various services published via the WSDL and I am able to use several with no issues. Here's the list: array(12) { [0]=> string(77) "GetGPTimerChannelsResponse GetGPTimerChannels(GetGPTimerChannels $parameters)" [1]=> string(74) "GetGPTimerChannelResponse GetGPTimerChannel(GetGPTimerChannel $parameters)" [2]=> string(74) "SetGPTimerChannelResponse SetGPTimerChannel(SetGPTimerChannel $parameters)" [3]=> string(47) "GetSlaveResponse GetSlave(GetSlave $parameters)" [4]=> string(71) "GetLogDataInlineResponse GetLogDataInline(GetLogDataInline $parameters)" [5]=> string(71) "GetLogItemInlineResponse GetLogItemInline(GetLogItemInline $parameters)" [6]=> string(59) "GetAlarmListResponse GetAlarmList(GetAlarmList $parameters)" [7]=> string(50) "GetSyslogResponse GetSyslog(GetSyslog $parameters)" [8]=> string(47) "SetSlaveResponse SetSlave(SetSlave $parameters)" [9]=> string(53) "GetVersionResponse GetVersion(GetVersion $parameters)" [10]=> string(53) "GetTDBInfoResponse GetTDBInfo(GetTDBInfo $parameters)" [11]=> string(53) "GetLogItemResponse GetLogItem(GetLogItem $parameters)" } I am trying to use the GetLogDataInline service which requires four parameters - these I'm passing as an array and all seems OK when doing the connection (the request/response takes around 30 seconds to process). When I look at a var_dump / print_r of the result, it returns NULL, whereas when I do a call to the __getLastResponse all of the data I need to populate my local database is there. Below is the code for the soapclient call: $client = new soapclient ("http://192.168.1.126/cgi-bin/cgi.cgi?WSDL", array("trace" => 1, "exceptions" => true, "cache_wsdl" => WSDL_CACHE_NONE, "features" => SOAP_SINGLE_ELEMENT_ARRAYS )); $params = array ( "ResponseType" => "Xml", "Step" => 15, "Start" => "2012-06-14T12:00:00+01:00", "End" => "2012-06-14T23:59:45+01:00" ); $result = $client -> GetLogDataInline ($params); An extract from the var_dump / __getLastResponse is: var_dump($client) object(SoapClient)#1 (4) { ["trace"]= int(1) ["_features"]= int(1) ["_soap_version"]= int(1) ["sdl"]= resource(4) of type (Unknown) } var_dump($result) NULL __getLastResponse 15 2012-06-14T12:00:00+01:00 2012-06-14T23:59:45+01:00 External Temperature Workshop Lux Level Electricity Pulse 100wh Workshop PIR Active Boiler Flow Temp Outside Lux Workshop_Light_Override_Hours Water Consumption (Litres) Electricity kWh Consumption Water Consumption M3 Gas kWh Consumption Outside Lighting Heating Effective Setpoint Router Reset Workshop Lighting State Heating Run Hours Heating On Receptin Percent RH Reception Temp Reception RH Reception Temp 2012-06-14T12:00:00+01:00 -85.6 2.1 -1.0 Off -91.5 13.8 0.0 -1.0 0.0 0.0 -0.1 Off 21.0 Off Off 0.0 Off 53.0 22.0 53.0 22.0 2012-06-14T12:00:15+01:00 -85.4 2.1 -1.0 Off -91.8 13.8 0.0 -1.0 0.0 0.0 -0.1 Off 21.0 Off Off 0.0 Off 53.0 22.0 53.0 22.0 2012-06-14T12:00:30+01:00 -85.4 2.1 -1.0 Off -91.8 13.8 0.0 -1.0 0.0 0.0 -0.1 Off 21.0 Off Off 0.0 Off 53.0 22.0 53.0 22.0 2012-06-14T12:00:45+01:00 -85.4 2.1 -1.0 Off -91.5 13.7 0.0 -1.0 0.0 0.0 -0.1 Off 21.0 Off Off 0.0 Off 54.0 22.0 54.0 22.0 (this should be xml but doesn't appear to have copied correctly) If you've got this far, thanks for taking the time.

• Google respond differently to two identical nginx setups and 200 codes; any ideas?

  - by Yuji Tomita

  I'm rather confused... I have a linode.com VPS which has been cloned recently, so the settings are the same between nginx servers. One lives on a dev subdomain, one on a www. I'm trying to run a google experiment on my live server, which claims: Web server rejects utm_expid. Your server doesn't support added query arguments in URLs. My logs show on the dev server where it works: 74.125.186.32 - - [13/Sep/2012:13:33:45 -0700] "GET /product/iphone-case/?utm_expid=25706866-0 HTTP/1.1" 200 12521 "-" "Google_Analytics_Content_Experiments 74.125.186.32 - - [13/Sep/2012:13:33:45 -0700] "GET /product/iphone-case/?ab_reviews=True&utm_expid=25706866-0 HTTP/1.1" 200 14679 "-" "Google_Analytics_Content_Experiments My production server shows google making a second request. 74.125.186.41 - - [13/Sep/2012:13:34:49 -0700] "GET /product/iphone-case/?ab_reviews=on&utm_expid=25706866-1 HTTP/1.1" 200 12104 "-" "Google_Analytics_Content_Experiments 74.125.186.41 - - [13/Sep/2012:13:34:49 -0700] "GET /product/iphone-case/?utm_expid=25706866-1 HTTP/1.1" 200 12122 "-" "Google_Analytics_Content_Experiments 74.125.186.41 - - [13/Sep/2012:13:34:49 -0700] "GET /product/iphone-case/ <--- A second request for some reason.

• Recurring events repeatedly saves a draft every minute

  - by Henrik Rasmussen

  Using Outlook 2010, some of my recurring (planned, not drafts) events is saving a draft to my Drafts folder every single minute as long as it's active. An example taken from real life is that I have a calendar entry (Appointment) occuring every day from 24-09-2012 until 28-09-2012 from 08:00 to 16:00 (GMT+1) with a blue category, only one participant (me) with subject but without a place. So every minute from 24-09-2012 until 28-09-2012 from 08:00 to 16:00, but not from 16:00 to 08:00, a new draft is automatically saved in my Drafts folder. How do I get rid of that behaviour? Addition here: Removing the offending event just allows a new one to take its place. There doesn't seem to be much on the sites - Microsoft calls it a "personal" issue, but there are more and more instances.

• Having trouble with time.sleep

  - by Waterfox

  When I run, for example: print("[",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("=",end=" ") time.sleep(1) print("]",end=" ") Nothing happens for 10 seconds, then the whole [ = = = = = = = = = = ] appears. How can I prevent that so that it can act as a sort of progress bar?
