• Cloud to On-Premise Connectivity Patterns

  - by Rajesh Raheja

  Do you have a requirement to convert an Opportunity in Salesforce.com to an Order/Quote in Oracle E-Business Suite? Or maybe you want the creation of an Oracle RightNow Incident to trigger an on-premise Oracle E-Business Suite Service Request creation for RMA and Field Scheduling? If so, read on. In a previous blog post, I discussed integrating TO cloud applications, however the use cases above are the reverse i.e. receiving data FROM cloud applications (SaaS) TO on-premise applications/databases that sit behind a firewall. Oracle SOA Suite is assumed to be on-premise with with Oracle Service Bus as the mediation and virtualization layer. The main considerations for the patterns are are security i.e. shielding enterprise resources; and scalability i.e. minimizing firewall latency. Let me use an analogy to help visualize the patterns: the on-premise system is your home - with your most valuable possessions - and the SaaS app is your favorite on-line store which regularly ships (inbound calls) various types of parcels/items (message types/service operations). You need the items at home (on-premise) but want to safe guard against misguided elements of society (internet threats) who may masquerade as postal workers and vandalize property (denial of service?). Let's look at the patterns. Pattern: Pull from Cloud The on-premise system polls from the SaaS apps and picks up the message instead of having it delivered. This may be done using Oracle RightNow Object Query Language or SOAP APIs. This is particularly suited for certain integration approaches wherein messages are trickling in, can be centralized and batched e.g. retrieving event notifications on an hourly schedule from the Oracle Messaging Service. To compare this pattern with the home analogy, you are avoiding any deliveries to your home and instead go to the post office/UPS/Fedex store to pick up your parcel. Every time. Pros: On-premise assets not exposed to the Internet, firewall issues avoided by only initiating outbound connections Cons: Polling mechanisms may affect performance, may not satisfy near real-time requirements Pattern: Open Firewall Ports The on-premise system exposes the web services that needs to be invoked by the cloud application. This requires opening up firewall ports, routing calls to the appropriate internal services behind the firewall. Fusion Applications uses this pattern, and auto-provisions the services on the various virtual hosts to secure the topology. This works well for service integration, but may not suffice for large volume data integration. Using the home analogy, you have now decided to receive parcels instead of going to the post office every time. A door mail slot cut out allows the postman can drop small parcels, but there is still concern about cutting new holes for larger packages. Pros: optimal pattern for near real-time needs, simpler administration once the service is provisioned Cons: Needs firewall ports to be opened up for new services, may not suffice for batch integration requiring direct database access Pattern: Virtual Private Networking The on-premise network is "extended" to the cloud (or an intermediary on-demand / managed service offering) using Virtual Private Networking (VPN) so that messages are delivered to the on-premise system in a trusted channel. Using the home analogy, you entrust a set of keys with a neighbor or property manager who receives the packages, and then drops it inside your home. Pros: Individual firewall ports don't need to be opened, more suited for high scalability needs, can support large volume data integration, easier management of one connection vs a multitude of open ports Cons: VPN setup, specific hardware support, requires cloud provider to support virtual private computing Pattern: Reverse Proxy / API Gateway The on-premise system uses a reverse proxy "API gateway" software on the DMZ to receive messages. The reverse proxy can be implemented using various mechanisms e.g. Oracle API Gateway provides firewall and proxy services along with comprehensive security, auditing, throttling benefits. If a firewall already exists, then Oracle Service Bus or Oracle HTTP Server virtual hosts can provide reverse proxy implementations on the DMZ. Custom built implementations are also possible if specific functionality (such as message store-n-forward) is needed. In the home analogy, this pattern sits in between cutting mail slots and handing over keys. Instead, you install (and maintain) a mailbox in your home premises outside your door. The post office delivers the parcels in your mailbox, from where you can securely retrieve it. Pros: Very secure, very flexible Cons: Introduces a new software component, needs DMZ deployment and management Pattern: On-Premise Agent (Tunneling) A light weight "agent" software sits behind the firewall and initiates the communication with the cloud, thereby avoiding firewall issues. It then maintains a bi-directional connection either with pull or push based approaches using (or abusing, depending on your viewpoint) the HTTP protocol. Programming protocols such as Comet, WebSockets, HTTP CONNECT, HTTP SSH Tunneling etc. are possible implementation options. In the home analogy, a resident receives the parcel from the postal worker by opening the door, however you still take precautions with chain locks and package inspections. Pros: Light weight software, IT doesn't need to setup anything Cons: May bypass critical firewall checks e.g. virus scans, separate software download, proliferation of non-IT managed software Conclusion The patterns above are some of the most commonly encountered ones for cloud to on-premise integration. Selecting the right pattern for your project involves looking at your scalability needs, security restrictions, sync vs asynchronous implementation, near real-time vs batch expectations, cloud provider capabilities, budget, and more. In some cases, the basic "Pull from Cloud" may be acceptable, whereas in others, an extensive VPN topology may be well justified.

• Selling Federal Enterprise Architecture (EA)

  - by TedMcLaughlan

  Selling Federal Enterprise Architecture A taxonomy of subject areas, from which to develop a prioritized marketing and communications plan to evangelize EA activities within and among US Federal Government organizations and constituents. Any and all feedback is appreciated, particularly in developing and extending this discussion as a tool for use – more information and details are also available. "Selling" the discipline of Enterprise Architecture (EA) in the Federal Government (particularly in non-DoD agencies) is difficult, notwithstanding the general availability and use of the Federal Enterprise Architecture Framework (FEAF) for some time now, and the relatively mature use of the reference models in the OMB Capital Planning and Investment (CPIC) cycles. EA in the Federal Government also tends to be a very esoteric and hard to decipher conversation – early apologies to those who agree to continue reading this somewhat lengthy article. Alignment to the FEAF and OMB compliance mandates is long underway across the Federal Departments and Agencies (and visible via tools like PortfolioStat and ITDashboard.gov – but there is still a gap between the top-down compliance directives and enablement programs, and the bottom-up awareness and effective use of EA for either IT investment management or actual mission effectiveness. "EA isn't getting deep enough penetration into programs, components, sub-agencies, etc.", verified a panelist at the most recent EA Government Conference in DC. Newer guidance from OMB may be especially difficult to handle, where bottom-up input can't be accurately aligned, analyzed and reported via standardized EA discipline at the Agency level – for example in addressing the new (for FY13) Exhibit 53D "Agency IT Reductions and Reinvestments" and the information required for "Cloud Computing Alternatives Evaluation" (supporting the new Exhibit 53C, "Agency Cloud Computing Portfolio"). Therefore, EA must be "sold" directly to the communities that matter, from a coordinated, proactive messaging perspective that takes BOTH the Program-level value drivers AND the broader Agency mission and IT maturity context into consideration. Selling EA means persuading others to take additional time and possibly assign additional resources, for a mix of direct and indirect benefits – many of which aren't likely to be realized in the short-term. This means there's probably little current, allocated budget to work with; ergo the challenge of trying to sell an "unfunded mandate". Also, the concept of "Enterprise" in large Departments like Homeland Security tends to cross all kinds of organizational boundaries – as Richard Spires recently indicated by commenting that "...organizational boundaries still trump functional similarities. Most people understand what we're trying to do internally, and at a high level they get it. The problem, of course, is when you get down to them and their system and the fact that you're going to be touching them...there's always that fear factor," Spires said. It is quite clear to the Federal IT Investment community that for EA to meet its objective, understandable, relevant value must be measured and reported using a repeatable method – as described by GAO's recent report "Enterprise Architecture Value Needs To Be Measured and Reported". What's not clear is the method or guidance to sell this value. In fact, the current GAO "Framework for Assessing and Improving Enterprise Architecture Management (Version 2.0)", a.k.a. the "EAMMF", does not include words like "sell", "persuade", "market", etc., except in reference ("within Core Element 19: Organization business owner and CXO representatives are actively engaged in architecture development") to a brief section in the CIO Council's 2001 "Practical Guide to Federal Enterprise Architecture", entitled "3.3.1. Develop an EA Marketing Strategy and Communications Plan." Furthermore, Core Element 19 of the EAMMF is advised to be applied in "Stage 3: Developing Initial EA Versions". This kind of EA sales campaign truly should start much earlier in the maturity progress, i.e. in Stages 0 or 1. So, what are the understandable, relevant benefits (or value) to sell, that can find an agreeable, participatory audience, and can pave the way towards success of a longer-term, funded set of EA mechanisms that can be methodically measured and reported? Pragmatic benefits from a useful EA that can help overcome the fear of change? And how should they be sold? Following is a brief taxonomy (it's a taxonomy, to help organize SME support) of benefit-related subjects that might make the most sense, in creating the messages and organizing an initial "engagement plan" for evangelizing EA "from within". An EA "Sales Taxonomy" of sorts. We're not boiling the ocean here; the subjects that are included are ones that currently appear to be urgently relevant to the current Federal IT Investment landscape. Note that successful dialogue in these topics is directly usable as input or guidance for actually developing early-stage, "Fit-for-Purpose" (a DoDAF term) Enterprise Architecture artifacts, as prescribed by common methods found in most EA methodologies, including FEAF, TOGAF, DoDAF and our own Oracle Enterprise Architecture Framework (OEAF). The taxonomy below is organized by (1) Target Community, (2) Benefit or Value, and (3) EA Program Facet - as in: "Let's talk to (1: Community Member) about how and why (3: EA Facet) the EA program can help with (2: Benefit/Value)". Once the initial discussion targets and subjects are approved (that can be measured and reported), a "marketing and communications plan" can be created. A working example follows the Taxonomy.

EA Program Facet (What parts of the EA can and should be communicated, using business or mission terms?) 3.1. Architecture Models – the visual tools to be created and used 3.1.1. Operating Architecture – the Business Operating Model/Architecture elements of the EA truly drive all other elements, plus expose communication channels 3.1.2. Use Of – how can the EA models be used, and how are they populated, from a reasonable, pragmatic yet compliant perspective? What are the core/minimal models required? What's the relationship of these models, with existing system models? 3.1.3. Scope – what level of granularity within the models, and what level of abstraction across the models, is likely to be most effective and useful? 3.2. Traceability – the maturity, status, completeness of the tools 3.2.1. Status – what in fact is the degree of maturity across the integrated EA model and other relevant governance models, and who may already be benefiting from it? 3.2.2. Visibility – how does the EA visibly and effectively prove IT investment performance goals are being reached, with positive mission outcome? 3.3. Governance – what's the interaction, participation method; how are the tools used? 3.3.1. Contributions – how is the EA program informed, accept submissions, collect data? Who are the experts? 3.3.2. Review – how is the EA validated, against what criteria?  Taxonomy Usage Example:   1. To speak with: a. ...a particular set of System Owners Facing Strategic Change, via mandate (like the "Cloud First" mandate); about... b. ...how the EA program's visible and easily accessible Infrastructure Reference Model (i.e. "IRM" or "TRM"), if updated more completely with current system data, can... c. ...help shed light on ways to mitigate risks and avoid future costs associated with NOT leveraging potentially-available shared services across the enterprise... 2. ....the following Marketing & Communications (Sales) Plan can be constructed: a. Create an easy-to-read "Consequence Model" that illustrates how adoption of a cloud capability (like elastic operational storage) can enable rapid and durable compliance with the mandate – using EA traceability. Traceability might be from the IRM to the ARM (that identifies reusable services invoking the elastic storage), and then to the PRM with performance measures (such as % utilization of purchased storage allocation) included in the OMB Exhibits; and b. Schedule a meeting with the Program Owners, timed during their Acquisition Strategy meetings in response to the mandate, to use the "Consequence Model" for advising them to organize a rapid and relevant RFI solicitation for this cloud capability (regarding alternatives for sourcing elastic operational storage); and c. Schedule a series of short "Discovery" meetings with the system architecture leads (as agreed by the Program Owners), to further populate/validate the "As-Is" models and frame the "To Be" models (via scenarios), to better inform the RFI, obtain the best feedback from the vendor community, and provide potential value for and avoid impact to all other programs and systems. --end example -- Note that communications with the intended audience should take a page out of the standard "Search Engine Optimization" (SEO) playbook, using keywords and phrases relating to "value" and "outcome" vs. "compliance" and "output". Searches in email boxes, internal and external search engines for phrases like "cost avoidance strategies", "mission performance metrics" and "innovation funding" should yield messages and content from the EA team. This targeted, informed, practical sales approach should result in additional buy-in and participation, additional EA information contribution and model validation, development of more SMEs and quick "proof points" (with real-life testing) to bolster the case for EA. The proof point here is a successful, timely procurement that satisfies not only the external mandate and external oversight review, but also meets internal EA compliance/conformance goals and therefore is more transparently useful across the community. In short, if sold effectively, the EA will perform and be recognized. EA won’t therefore be used only for compliance, but also (according to a validated, stated purpose) to directly influence decisions and outcomes. The opinions, views and analysis expressed in this document are those of the author and do not necessarily reflect the views of Oracle.

  I'm having problems mounting the recovery image. I've tried to mount the image multiple ways. quark@DS9 ~ $ sudo mount -t ext4 /media/jump1/1recover/sdb1.img /mnt mount: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so quark@DS9 ~ $ sudo mount -r -o loop /media/jump1/1recover/sdb1.img recover mount: you must specify the filesystem type quark@DS9 ~ $ sudo mount /media/jump1/1recover/sdb1.img mnt mount: you must specify the filesystem type It doesn't even give me detailed information on the file I just made, nautilus says it's 160gb. quark@DS9 ~ $ file /media/jump1/1recover/sdb1.img /media/jump1/1recover/sdb1.img: data quark@DS9 ~ $ mmls /media/jump1/1recover/sdb1.img Cannot determine partition type I'm not sure what I'm doing wrong or if I started this process incorrectly from the beginning.

One has the dual boot Win7 / Linux Mint system files. Secondary one contained my /home folder. The laptop was jarred and the /home disk was broken. I tried a LiveCD recovery, it failed. Wouldn't even load a Live session with the disk installed.

• Twitter Customer Sentiment Analysis

  - by Liam McLennan

  The breakable toy that I am currently working on is a twitter customer sentiment analyser. It scrapes twitter for tweets relating to a particular organisation, applies a machine learning algorithm to determine if the content of tweet is positive or negative, and generates reports of the sentiment data over time, correlated to dates, events and news feeds. I’m having lots of fun building this, but I would also like to learn if there is a market for quantified sentiment data. So that I can start to show people what I have in mind I have created a mockup of the simplest and most important report. It shows customer sentiment over time, with important events highlighted. As the user moves their mouse to the right (forward in time) the source data area scrolls up to display the tweets from that time. The tweets are colour coded based on sentiment rating. After I started working on this project I discovered that a team of students have already built something similar. It is a lot of fun to enter your employers name and see what it says.

• Mediamonkey ratings imported into Rhythmbox/Banshee/Quod Libet

  - by JoshK

  I recently made a complete shift from Windows 7 to Ubuntu 12.04. Everything went smoothly until I scanned my music files in some of the Ubuntu players... All of my ratings added in Windows, using Mediamonkey, were out-of-five-stars (some with a half-star precision) - but when imported into RhythmBox, Banshee and Quod Libet, they all changed to a out-of-four-stars rating, with no five-star songs and no indication of how the old ratings were mapped into the new system. Does anyone know how to fix this? Even getting to know which way the ratings were mapped from 5-star system (with a half-star increment) to a 4-star basis will be very helpful. Thank you!

• Google is still crawling and indexing my old, dummy, test pages which now are 404 not found

  - by Ace

  I have set up my site with sample pages and data (lorem ipsum, etc..) and Google has crawled these pages. I deleted all these pages and actually added real content but in webmaster tools, i still get a lot of 404 errors Google trying to crawl these pages. I have set them to "mark as resolved" but some pages still come back as 404. Furthermore, I have a lot of these sample pages still listed when i do a search of my site on Google. How to remove them. I think these irrelevant pages are hurting my rating. I actually wanted to erase all these pages and start getting my site being being indexed as a new one but I read it's not possible? (I have submitted a sitemap and used "Fetch as Google.")

• How will this affect my SEO ranking?

  - by dunc

  I run a fishkeeping website based on a WordPress (PHP) CMS. I've recently put a fairly complex "filter" into place which searches my content for mentions of fish species profiles and turns them into an active link. For example, asdasd this is a test about abdomen to see if the caudal fin will work asdadasdas try again with abdomen and A. panduro and Apistogramma panduro ...becomes asdasd this is a test about abdomen to see if the caudal fin will work asdadasdas try again with abdomen and <a href="/?p=1703" class="link_species">A. panduro</a> and <a href="/?p=1703" class="link_species">Apistogramma panduro</a> On the rest of my website, the species are linked with pretty URLs such as /species/apistogramma-panduro/ but due to the way this filter works, the only information I can get access to is the idof the post. As such, I'm using /?p=1703 or whatever the ID is. What I'd like to know is: how much will this affect my SEO rating/ranking? Will it be detrimental if I don't rewrite the function? Thanks in advance,

• Is there a 'design pattern' type listing of common algorithms?

  - by KevinM1

  Is there a 'design pattern' styled listing of common/popular algorithms anywhere? Specifically, something that has a similar format along the lines of: Algorithm Name: e.g., Quick Sort, Bubble Sort, etc. Problem: A description of the stereotypical problem the algorithm is supposed to address Description: Description of the solution Implementation: Code examples of the solution Big O Rating: Self-explanatory Similar Algorithms: Algorithms that address the same problem in different ways, or similar problems I really like the GoF design pattern listing style, and I think it would help me learn various algorithms better/easier if I could find a resource that was similar in terms of organization.

• CMS/platform/portal for personnel placement/recruiting [closed]

  - by mezzanine

  Possible Duplicate: Which Content Management System (CMS)/Wiki should I use? I am interested in building a platform where I can match specialists/experts in a certain profession with potential customers/clients. Therefore, the professionals should be able to register with information about them and their area of expertise, and customers should be able to search for them and contact them via my website. Bonus would be some kind of feedback or rating functionality. Examples for other areas are http://www.lawyers.com/ for lawyers and http://sortfolio.com/ for web designers. Is there some kind of platform which already provides this functionality and could be customized?

• Using repaint() method.

  - by owca

  I'm still struggling to create this game : http://stackoverflow.com/questions/2844190/choosing-design-method-for-ladder-like-word-game .I've got it almost working but there is a problem though. When I'm inserting a word and it's correct, the whole window should reload, and JButtons containing letters should be repainted with different style.

• jqgrid with asp.net webmethod and json working with sorting, paging, searching and LINQ

  - by aimlessWonderer

  THIS WORKS! Most topics covering jqgrid and asp.net seem to relate to just receiving JSON, or working in the MVC framework, or utilizing other handlers or web services... but not many dealt with actually passing parameters back to an actual webmethod in the codebehind. Furthermore, scarce are the examples that contain successful implementation the AJAX paging, sorting, or searching along with LINQ to SQL for asp.net jqGrid. Below is a working example that may help others who need help to pass parameters to jqGrid in order to have correct paging, sorting, filtering.. it uses pieces from here and there... ================================================== First, THE JAVASCRIPT <script type="text/javascript"> $(document).ready(function() { var grid = $("#list"); $("#list").jqGrid({ // setup custom parameter names to pass to server prmNames: { search: "isSearch", nd: null, rows: "numRows", page: "page", sort: "sortField", order: "sortOrder" }, // add by default to avoid webmethod parameter conflicts postData: { searchString: '', searchField: '', searchOper: '' }, // setup ajax call to webmethod datatype: function(postdata) { mtype: "GET", $.ajax({ url: 'PageName.aspx/getGridData', type: "POST", contentType: "application/json; charset=utf-8", data: JSON.stringify(postdata), dataType: "json", success: function(data, st) { if (st == "success") { var grid = jQuery("#list")[0]; grid.addJSONData(JSON.parse(data.d)); } }, error: function() { alert("Error with AJAX callback"); } }); }, // this is what jqGrid is looking for in json callback jsonReader: { root: "rows", page: "page", total: "totalpages", records: "totalrecords", cell: "cell", id: "id", //index of the column with the PK in it userdata: "userdata", repeatitems: true }, colNames: ['Id', 'First Name', 'Last Name'], colModel: [ { name: 'id', index: 'id', width: 55, search: false }, { name: 'fname', index: 'fname', width: 200, searchoptions: { sopt: ['eq', 'ne', 'cn']} }, { name: 'lname', index: 'lname', width: 200, searchoptions: { sopt: ['eq', 'ne', 'cn']} } ], rowNum: 10, rowList: [10, 20, 30], pager: jQuery("#pager"), sortname: "fname", sortorder: "asc", viewrecords: true, caption: "Grid Title Here" }).jqGrid('navGrid', '#pager', { edit: false, add: false, del: false }, {}, // default settings for edit {}, // add {}, // delete { closeOnEscape: true, closeAfterSearch: true}, //search {} ) }); </script> ================================================== Second, THE C# WEBMETHOD [WebMethod] public static string getGridData(int? numRows, int? page, string sortField, string sortOrder, bool isSearch, string searchField, string searchString, string searchOper) { string result = null; MyDataContext db = null; try { //--- retrieve the data db = new MyDataContext("my connection string path"); var query = from u in db.TBL_USERs select u; //--- determine if this is a search filter if (isSearch) { searchOper = getOperator(searchOper); // need to associate correct operator to value sent from jqGrid string whereClause = String.Format("{0} {1} {2}", searchField, searchOper, "@" + searchField); //--- associate value to field parameter Dictionary<string, object> param = new Dictionary<string, object>(); param.Add("@" + searchField, searchString); query = query.Where(whereClause, new object[1] { param }); } //--- setup calculations int pageIndex = page ?? 1; //--- current page int pageSize = numRows ?? 10; //--- number of rows to show per page int totalRecords = query.Count(); //--- number of total items from query int totalPages = (int)Math.Ceiling((decimal)totalRecords / (decimal)pageSize); //--- number of pages //--- filter dataset for paging and sorting IQueryable<TBL_USER> orderedRecords = query.OrderBy(sortfield); IEnumerable<TBL_USER> sortedRecords = orderedRecords.ToList(); if (sortorder == "desc") sortedRecords= sortedRecords.Reverse(); sortedRecords= sortedRecords .Skip((pageIndex - 1) * pageSize) //--- page the data .Take(pageSize); //--- format json var jsonData = new { totalpages = totalPages, //--- number of pages page = pageIndex, //--- current page totalrecords = totalRecords, //--- total items rows = ( from row in sortedRecords select new { i = row.USER_ID, cell = new string[] { row.USER_ID.ToString(), row.FNAME.ToString(), row.LNAME } } ).ToArray() }; result = Newtonsoft.Json.JsonConvert.SerializeObject(jsonData); } catch (Exception ex) { Debug.WriteLine(ex); } finally { if (db != null) db.Dispose(); } return result; } ================================================== Third, NECESSITIES In order to have dynamic OrderBy clauses in the LINQ, I had to pull in a class to my AppCode folder called 'Dynamic.cs'. You can retrieve the file from downloading here. You will find the file in the "DynamicQuery" folder. That file will give you the ability to utilized dynamic ORDERBY clause since we don't know what column we're filtering by except on the initial load. To serialize the JSON back from the C-sharp to the JS, I incorporated the James Newton-King JSON.net DLL found here : http://json.codeplex.com/releases/view/37810. After downloading, there is a "Newtonsoft.Json.Compact.dll" which you can add in your Bin folder as a reference Here's my USING's block using System; using System.Collections; using System.Collections.Generic; using System.Linq; using System.Web.UI.WebControls; using System.Web.Services; using System.Linq.Dynamic; For the Javascript references, I'm using the following scripts in respective order in case that helps some folks: 1) jquery-1.3.2.min.js ... 2) jquery-ui-1.7.2.custom.min.js ... 3) json.min.js ... 4) i18n/grid.locale-en.js ... 5) jquery.jqGrid.min.js For the CSS, I'm using jqGrid's necessities as well as the jQuery UI Theme: 1) jquery_theme/jquery-ui-1.7.2.custom.css ... 2) ui.jqgrid.css The key to getting the parameters from the JS to the WebMethod without having to parse an unserialized string on the backend or having to setup some JS logic to switch methods for different numbers of parameters was this block postData: { searchString: '', searchField: '', searchOper: '' }, Those parameters will still be set correctly when you actually do a search and then reset to empty when you "reset" or want the grid to not do any filtering Hope this helps some others!!!! Please reply if you find major issues or ways of refactoring or doing better that I haven't considered.

• Cannot Start Nginx Compiled from Source

  - by Jason Alan Kennedy

  I am trying to compile Nginx from source based on the original compiled Nginx server running on my DigitalOcean server ( Ubuntu-14.04 64x ) but with a few extra modules. I can get everything installed smoothly but I can not get it to start. I am sure the ini is correct because I copied the original source off the current running Nginx server [ Even though I see that Nginx now adds the ini when compiling fron source ]. Below is the [ lengthy process ] that I am performing - add sorry but I wanted to be thorough for those who are in need of the info ]. Because I am a newB to Nginx, I am sure I am missing something or just have it all wrong. If you may look over what I have done and see if you spot anything I need/need to change, I will greatly appreciate it. Thnx! With the original Nginx server still running: I check the current/running Nginx configuration so I can build the new Nginx instance the same but with the added modules: nginx -V # The out-put: configure arguments: --with-cc-opt='-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2' --with-ld-opt='-Wl,-Bsymbolic-functions -Wl,-z,relro' --prefix=/usr/share/nginx --conf-path=/etc/nginx/nginx.conf --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log --lock-path=/var/lock/nginx.lock --pid-path=/run/nginx.pid --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --with-debug --with-pcre-jit --with-ipv6 --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-http_addition_module --with-http_dav_module --with-http_geoip_module --with-http_gzip_static_module --with-http_image_filter_module --with-http_spdy_module --with-http_sub_module --with-http_xslt_module NOTE: The configure arguments below return errors during 'make' so I removed them.

Next I copy the old /etc/nginx/nginx.conf, /etc/nginx/sites-available/default, /etc/nginx/sites-enabled/default, /etc/init.d/nginx to a text file locally for safe keeping to use in the new Nginx server. Then stop the running Nginx server: service nginx stop , verify it's stopped: service --status-all and the output is: [ - ] nginx To verify that there are two Nginx directories, I cd to: cd nginx* and the output is an error indicating there are two nginx folders - Cool Beans! :) Now Install the new Nginx server: cd nginx-1.7.4 make install # INSTALL OUTPUT ######################################## make -f objs/Makefile install make[1]: Entering directory `/home/walkingfish/nginx-1.7.4' test -d '/usr/share/nginx' || mkdir -p '/usr/share/nginx' test -d '/usr/share/nginx/sbin' || mkdir -p '/usr/share/nginx/sbin' test ! -f '/usr/share/nginx/sbin/nginx' || mv '/usr/share/nginx/sbin/nginx' '/usr/share/nginx/sbin/nginx.old' cp objs/nginx '/usr/share/nginx/sbin/nginx' test -d '/etc/nginx' || mkdir -p '/etc/nginx' cp conf/koi-win '/etc/nginx' cp conf/koi-utf '/etc/nginx' cp conf/win-utf '/etc/nginx' test -f '/etc/nginx/mime.types' || cp conf/mime.types '/etc/nginx' cp conf/mime.types '/etc/nginx/mime.types.default' test -f '/etc/nginx/fastcgi_params' || cp conf/fastcgi_params '/etc/nginx' cp conf/fastcgi_params '/etc/nginx/fastcgi_params.default' test -f '/etc/nginx/fastcgi.conf' || cp conf/fastcgi.conf '/etc/nginx' cp conf/fastcgi.conf '/etc/nginx/fastcgi.conf.default' test -f '/etc/nginx/uwsgi_params' || cp conf/uwsgi_params '/etc/nginx' cp conf/uwsgi_params '/etc/nginx/uwsgi_params.default' test -f '/etc/nginx/scgi_params' || cp conf/scgi_params '/etc/nginx' cp conf/scgi_params '/etc/nginx/scgi_params.default' test -f '/etc/nginx/nginx.conf' || cp conf/nginx.conf '/etc/nginx/nginx.conf' cp conf/nginx.conf '/etc/nginx/nginx.conf.default' test -d '/run' || mkdir -p '/run' test -d '/var/log/nginx' || mkdir -p '/var/log/nginx' test -d '/usr/share/nginx/html' || cp -R html '/usr/share/nginx' test -d '/var/log/nginx' || mkdir -p '/var/log/nginx' ######################################################### I copy/create the files that I saved earlier to txt files in sites-available, the config, default and ini files then symlink them to sites-enabled, and so on.

Also with nginx -V and its not installed??? I reboot the system too and still nothing. So I am not sure what is wrong here. The ini was copied over from the old server along with all the other config files after deleting the old files. When I opened the new compiled files, the nginx default data was present so I replaced them with my old original data prior to starting the new server for the first time. Also to be safe, I rm /etc/nginx/sites-enabled/default and symlinked with ln -s /etc/nginx/sites-available/default /etc/nginx/sites-enabled/default with no errors and I verified that the data was in the sites-enabled/default file. I don't think the server really/fully installed because of the nginx -V result: The program 'nginx' can be found in the following packages: * nginx-core * nginx-extras * nginx-full * nginx-light * nginx-naxsi Try: apt-get install <selected package> Do/should I apt-get install nginx-1.7.4 ?? Or what package do I use being that its a custom package and make install earlier did nothing?? If you need to see the conf files I copied over from the old to the custom server, LMK and I'll post them. Again your help here would be appreciated!

• Unable to Create New Incidents in Dynamics CRM with Java and Axis2

  - by Lutz

  So I've been working on trying to figure this out, oddly when I ran it one machine I got a generic Axis Fault with no description, but now on another machine I'm getting a different error message, but I'm still stuck. Basically I'm just trying to do what I thought would be a fairly trivial task of creating a new incident in Microsoft Dynamics CRM 4.0 via a web services call. I started by downloading the XML from http://hostname/MSCrmServices/2007/CrmService.asmx and generating code from it using Axis2. Anyway, here's my program, any help would be greatly appreciated, as I've been stuck on this for way longer than I thought I'd be and I'm really out of ideas here. public class TestCRM { private static String endpointURL = "http://theHost/MSCrmServices/2007/CrmService.asmx"; private static String userName = "myUserNameHere"; private static String password = "myPasswordHere"; private static String host = "theHostname"; private static int port = 80; private static String domain = "theDomain"; private static String orgName = "theOrganization"; public static void main(String[] args) { CrmServiceStub stub; try { stub = new CrmServiceStub(endpointURL); setOptions(stub._getServiceClient().getOptions()); RetrieveMultipleDocument rmd = RetrieveMultipleDocument.Factory.newInstance(); com.microsoft.schemas.crm._2007.webservices.RetrieveMultipleDocument.RetrieveMultiple rm = com.microsoft.schemas.crm._2007.webservices.RetrieveMultipleDocument.RetrieveMultiple.Factory.newInstance(); QueryExpression query = QueryExpression.Factory.newInstance(); query.setColumnSet(AllColumns.Factory.newInstance()); query.setEntityName(EntityName.INCIDENT.toString()); rm.setQuery(query); rmd.setRetrieveMultiple(rm); TargetCreateIncident tinc = TargetCreateIncident.Factory.newInstance(); Incident inc = tinc.addNewIncident(); inc.setDescription("This is a test of ticket creation through a web services call."); CreateDocument cd = CreateDocument.Factory.newInstance(); Create create = Create.Factory.newInstance(); create.setEntity(inc); cd.setCreate(create); Incident test = (Incident)cd.getCreate().getEntity(); CrmAuthenticationTokenDocument catd = CrmAuthenticationTokenDocument.Factory.newInstance(); CrmAuthenticationToken token = CrmAuthenticationToken.Factory.newInstance(); token.setAuthenticationType(0); token.setOrganizationName(orgName); catd.setCrmAuthenticationToken(token); //The two printlns below spit back XML that looks okay to me? System.out.println(cd); System.out.println(catd); /* stuff that doesn't work */ CreateResponseDocument crd = stub.create(cd, catd, null, null); //this line throws the error CreateResponse cr = crd.getCreateResponse(); System.out.println("create result: " + cr.getCreateResult()); /* End stuff that doesn't work */ System.out.println(); System.out.println(); System.out.println(); boolean fetchNext = true; while(fetchNext){ RetrieveMultipleResponseDocument rmrd = stub.retrieveMultiple(rmd, catd, null, null); //This retrieve using the CRMAuthenticationToken catd works just fine RetrieveMultipleResponse rmr = rmrd.getRetrieveMultipleResponse(); BusinessEntityCollection bec = rmr.getRetrieveMultipleResult(); String pagingCookie = bec.getPagingCookie(); fetchNext = bec.getMoreRecords(); ArrayOfBusinessEntity aobe = bec.getBusinessEntities(); BusinessEntity[] myEntitiesAtLast = aobe.getBusinessEntityArray(); for(int i=0; i<myEntitiesAtLast.length; i++){ //cast to whatever you asked for...

• C# serial port driver wrapper class code and concept quality

  - by Ruben Trancoso

  Hi folks, Would like to know from all you guys what you think about my Serial Wrapper class. Had be a while I've beem working with serial port but never shared the code what somekind make closed to my very own vision. Would like to know if it's a good/bad approach, if the interface is enough and what more you see on it. I know that Stackoverflow is for question but at the same time there's a lot of very good skilled people here and share code and opinion can also bennefit everybody, it's why I decided to post it anyway. thanks! using System.Text; using System.IO; using System.IO.Ports; using System; namespace Driver { class SerialSingleton { // The singleton instance reference private static SerialSingleton instance = null; // System's serial port interface private SerialPort serial; // Current com port identifier private string comPort = null; // Configuration parameters private int confBaudRate; private int confDataBits; private StopBits confStopBits; private Parity confParityControl; ASCIIEncoding encoding = new ASCIIEncoding(); // ================================================================================== // Constructors public static SerialSingleton getInstance() { if (instance == null) { instance = new SerialSingleton(); } return instance; } private SerialSingleton() { serial = new SerialPort(); } // =================================================================================== // Setup Methods public string ComPort { get { return comPort; } set { if (value == null) { throw new SerialException("Serial port name canot be null."); } if (nameIsComm(value)) { close(); comPort = value; } else { throw new SerialException("Serial Port '" + value + "' is not a valid com port."); } } } public void setSerial(string baudRate, int dataBits, StopBits stopBits, Parity parityControl) { if (baudRate == null) { throw new SerialException("Baud rate cannot be null"); } string[] baudRateRef = { "300", "600", "1200", "1800", "2400", "3600", "4800", "7200", "9600", "14400", "19200", "28800", "38400", "57600", "115200" }; int confBaudRate; if (findString(baudRateRef, baudRate) != -1) { confBaudRate = System.Convert.ToInt32(baudRate); } else { throw new SerialException("Baurate parameter invalid."); } int confDataBits; switch (dataBits) { case 5: confDataBits = 5; break; case 6: confDataBits = 6; break; case 7: confDataBits = 7; break; case 8: confDataBits = 8; break; default: throw new SerialException("Databits parameter invalid"); } if (stopBits == StopBits.None) { throw new SerialException("StopBits parameter cannot be NONE"); } this.confBaudRate = confBaudRate; this.confDataBits = confDataBits; this.confStopBits = stopBits; this.confParityControl = parityControl; } // ================================================================================== public string[] PortList { get { return SerialPort.GetPortNames(); } } public int PortCount { get { return SerialPort.GetPortNames().Length; } } // ================================================================================== // Open/Close Methods public void open() { open(comPort); } private void open(string comPort) { if (isOpen()) { throw new SerialException("Serial Port is Already open"); } else { if (comPort == null) { throw new SerialException("Serial Port not defined.

• Hibernate : load and

  - by Albert Kam

  According to the tutorial : http://jpa.ezhibernate.com/Javacode/learn.jsp?tutorial=27hibernateloadvshibernateget, If you initialize a JavaBean instance with a load method call, you can only access the properties of that JavaBean, for the first time, within the transactional context in which it was initialized. If you try to access the various properties of the JavaBean after the transaction that loaded it has been committed, you'll get an exception, a LazyInitializationException, as Hibernate no longer has a valid transactional context to use to hit the database. But with my experiment, using hibernate 3.6, and postgres 9, it doesnt throw any exception at all. Am i missing something ? Here's my code : import org.hibernate.Session; public class AppLoadingEntities { /** * @param args */ public static void main(String[] args) { HibernateUtil.beginTransaction(); Session session = HibernateUtil.getSession(); EntityUser userFromGet = get(session); EntityUser userFromLoad = load(session); // finish the transaction session.getTransaction().commit(); // try fetching field value from entity bean that is fetched via get outside transaction, and it'll be okay System.out.println("userFromGet.getId() : " + userFromGet.getId()); System.out.println("userFromGet.getName() : " + userFromGet.getName()); // fetching field from entity bean that is fetched via load outside transaction, and it'll be errornous // NOTE : but after testing, load seems to be okay, what gives ? ask forums try { System.out.println("userFromLoad.getId() : " + userFromLoad.getId()); System.out.println("userFromLoad.getName() : " + userFromLoad.getName()); } catch(Exception e) { System.out.println("error while fetching entity that is fetched from load : " + e.getMessage()); } } private static EntityUser load(Session session) { EntityUser user = (EntityUser) session.load(EntityUser.class, 1l); System.out.println("user fetched with 'load' inside transaction : " + user); return user; } private static EntityUser get(Session session) { // safe to set it to 1, coz the table got recreated at every run of this app EntityUser user = (EntityUser) session.get(EntityUser.class, 1l); System.out.println("user fetched with 'get' : " + user); return user; } } And here's the output : 88 [main] INFO org.hibernate.annotations.common.Version - Hibernate Commons Annotations 3.2.0.Final 93 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.6.0.Final 94 [main] INFO org.hibernate.cfg.Environment - hibernate.properties not found 96 [main] INFO org.hibernate.cfg.Environment - Bytecode provider name : javassist 98 [main] INFO org.hibernate.cfg.Environment - using JDK 1.4 java.sql.Timestamp handling 139 [main] INFO org.hibernate.cfg.Configuration - configuring from resource: /hibernate.cfg.xml 139 [main] INFO org.hibernate.cfg.Configuration - Configuration resource: /hibernate.cfg.xml 172 [main] WARN org.hibernate.util.DTDEntityResolver - recognized obsolete hibernate namespace http://hibernate.sourceforge.net/.

• Sharepoint : Access denied when editing a page (because of page layout) or list item

  - by tinky05

  I'm logged in as the System Account, so it's probably not a "real access denied"! What I've done : - A custom master page - A custom page layout from a custom content type (with custom fields) If I add a custom field (aka "content field" in the tools in SPD) in my page layout, I get an access denied when I try to edit a page that comes from that page layout. So, for example, if I add in my page layout this line in a "asp:content" tag : I get an access denied. If I remove it, everyting is fine. (the field "test" is a field that comes from the content type). Any idea? UPDATE Well, I tried in a blank site and it worked fine, so there must be something wrong with my web application :( UPDATE #2 Looks like this line in the master page gives me the access denied : <SharePoint:DelegateControl runat="server" ControlId="PublishingConsole" Visible="false" PrefixHtml="&lt;tr&gt;&lt;td colspan=&quot;0&quot; id=&quot;mpdmconsole&quot; class=&quot;s2i-consolemptablerow&quot;&gt;" SuffixHtml="&lt;/td&gt;&lt;/tr&gt;"></SharePoint:DelegateControl> UPDATE #3 I Found http://odole.wordpress.com/2009/01/30/access-denied-error-message-while-editing-properties-of-any-document-in-a-moss-document-library/ Looks like a similar issue. But our Sharepoint versions are with the latest updates. I'll try to use the code that's supposed to fix the lists and post another update. ** UPDATE #4** OK... I tried the code that I found on the page above (see link) and it seems to fix the thing. I haven't tested the solution at 100% but so far, so good. Here's the code I made for a feature receiver (I used the code posted from the link above) : using System; using System.Collections.Generic; using System.Text; using Microsoft.SharePoint; using System.Xml; namespace MyWebsite.FixAccessDenied { class FixAccessDenied : SPFeatureReceiver { public override void FeatureActivated(SPFeatureReceiverProperties properties) { FixWebField(SPContext.Current.Web); } public override void FeatureDeactivating(SPFeatureReceiverProperties properties) { //throw new Exception("The method or operation is not implemented."); } public override void FeatureInstalled(SPFeatureReceiverProperties properties) { //throw new Exception("The method or operation is not implemented."); } public override void FeatureUninstalling(SPFeatureReceiverProperties properties) { //throw new Exception("The method or operation is not implemented."); } static void FixWebField(SPWeb currentWeb) { string RenderXMLPattenAttribute = "RenderXMLUsingPattern"; SPSite site = new SPSite(currentWeb.Url); SPWeb web = site.OpenWeb(); web.AllowUnsafeUpdates = true; web.Update(); SPField f = web.Fields.GetFieldByInternalName("PermMask"); string s = f.SchemaXml; Console.WriteLine("schemaXml before: " + s); XmlDocument xd = new XmlDocument(); xd.LoadXml(s); XmlElement xe = xd.DocumentElement; if (xe.Attributes[RenderXMLPattenAttribute] == null) { XmlAttribute attr = xd.CreateAttribute(RenderXMLPattenAttribute); attr.Value = "TRUE"; xe.Attributes.Append(attr); } string strXml = xe.OuterXml; Console.WriteLine("schemaXml after: " + strXml); f.SchemaXml = strXml; foreach (SPWeb sites in site.AllWebs) { FixField(sites.Url); } } static void FixField(string weburl) { string RenderXMLPattenAttribute = "RenderXMLUsingPattern"; SPSite site = new SPSite(weburl); SPWeb web = site.OpenWeb(); web.AllowUnsafeUpdates = true; web.Update(); System.Collections.Generic.IList<Guid> guidArrayList = new System.Collections.Generic.List<Guid>(); foreach (SPList list in web.Lists) { guidArrayList.Add(list.ID); } foreach (Guid guid in guidArrayList) { SPList list = web.Lists[guid]; SPField f = list.Fields.GetFieldByInternalName("PermMask"); string s = f.SchemaXml; Console.WriteLine("schemaXml before: " + s); XmlDocument xd = new XmlDocument(); xd.LoadXml(s); XmlElement xe = xd.DocumentElement; if (xe.Attributes[RenderXMLPattenAttribute] == null) { XmlAttribute attr = xd.CreateAttribute(RenderXMLPattenAttribute); attr.Value = "TRUE"; xe.Attributes.Append(attr); } string strXml = xe.OuterXml; Console.WriteLine("schemaXml after: " + strXml); f.SchemaXml = strXml; } } } } Just put that code as a Feature Receiver, and activate it at the root site, it should loop trough all the subsites and fix the lists. SUMMARY You get an ACCESS DENIED when editing a PAGE or an ITEM You still get the error even if you're logged in as the Super Admin of the f****in world (sorry, I spent 3 days on that bug) For me, it happened after an import from another site definition (a cmp file) Actually, it's supposed to be a known bug and it's supposed to be fixed since February 2009, but it looks like it's not. The code I posted above should fix the thing.

• Unable to get HTTPS MEX endpoint to work

  - by Rahul

  I have been trying to configure WCF to work with Azure ACS. This WCF configuration has 2 bugs: It does not publish MEX end point. It does not invoke custom behaviour extension.

There is more code involved for checking token validation, but in my opinion at least MEX should get published and CreateBehavior() should get invoked in order for me to proceed further.

• Please help me correct the small bugs in this image editor

  - by Alex

  Hi, I'm working on a website that will sell hand made jewelry and I'm finishing the image editor, but it's not behaving quite right. Basically, the user uploads an image which will be saved as a source and then it will be resized to fit the user's screen and saved as a temp. The user will then go to a screen that will allow them to crop the image and then save it to it's final versions. All of that works fine, except, the final versions have 3 bugs. First is some black horizontal line on the very bottom of the image. Second is an outline of sorts that follows the edges. I thought it was because I was reducing the quality, but even at 100% it still shows up... And lastly, I've noticed that the cropped image is always a couple of pixels lower than what I'm specifying... Anyway, I'm hoping someone whose got experience in editing images with C# can maybe take a look at the code and see where I might be going off the right path. Oh, by the way, this in an ASP.NET MVC application. Here's the code: using System; using System.Drawing; using System.Drawing.Drawing2D; using System.Drawing.Imaging; using System.IO; using System.Linq; using System.Web; namespace Website.Models.Providers { public class ImageProvider { private readonly ProductProvider ProductProvider = null;
