  • SEO - What is That? - Why You Need to Do It!

    In this article I try to explain the differences between Internet Marketing and SEO or Search Engine Optimization in a simple form so it is easily understood. I think the importance of SEO is quite often overlooked for the easier and much emphasized way of marketing and that is email and lead generation marketing using a sequence of letters and auto responders. There is such a high failure rate in marketing today and I think part of that could be related to the form of marketing one is relying on.

  • How to do server-side validation using Jqgrid?

    - by Eoghan
    Hi, I'm using jqgrid to display a list of sites and I want to do some server side validation when a site is added or edited. (Form editing rather than inline. Validation needs to be server side for various reasons I won't go into.) I thought the best way would be to check the data via an ajax request when the beforeSubmit event is triggered. However this only seems to work when I'm editing an existing row in the grid - the function isn't called when I add a new row. Have I got my beforeSubmit in the wrong place? Thanks for your help. $("#sites-grid").jqGrid({ url:'/json/sites', datatype: "json", mtype: 'GET', colNames:['Code', 'Name', 'Area', 'Cluster', 'Date Live', 'Status', 'Lat', 'Lng'], colModel :[ {name:'code', index:'code', width:80, align:'left', editable:true}, {name:'name', index:'name', width:250, align:'left', editrules:{required:true}, editable:true}, {name:'area', index:'area', width:60, align:'left', editable:true}, {name:'cluster_id', index:'cluster_id', width:80, align:'right', editrules:{required:true, integer:true}, editable:true, edittype:"select", editoptions:{value:"<?php echo $cluster_options; ?>"}}, {name:'estimated_live_date', index:'estimated_live_date', width:120, align:'left', editable:true, editrules:{required:true}, edittype:"select", editoptions:{value:"<?php echo $this->month_options; ?>"}}, {name:'status', index:'status', width:80, align:'left', editable:true, edittype:"select", editoptions:{value:"Live:Live;Plan:Plan;"}}, {name:'lat', index:'lat', width:140, align:'right', editrules:{required:true}, editable:true}, {name:'lng', index:'lng', width:140, align:'right', editrules:{required:true}, editable:true}, ], height: '300', pager: '#pager-sites', rowNum:30, rowList:[10,30,90], sortname: 'cluster_id', sortorder: 'desc', viewrecords: true, multiselect: false, caption: 'Sites', editurl: '/json/sites' }); $("#sites-grid").jqGrid('navGrid','#pager-sites',{edit:true,add:true,del:true, beforeSubmit : function(postdata, formid) { $.ajax({ url : 'json/validate-site/', data : postdata, dataType : 'json', type : 'post', success : function(data) { alert(data.message); return[data.result, data.message]; } }); }});

  • Roadmap to Android development

    - by Matthew
    Hello, I've done a little research, and am interested in developing for Android. I've never programmed before, and have no idea how to go from zero experience to developing for a mobile device. My interest is in eventually making some sort of 2d game. Is there a lesson plan for starting from the ground up? I would think one would need to learn the Java language to start. Looking at the Sun website, it's a bit daunting. Is there a book, specifically, that would wrap up this knowledge in a bit of a directed lesson plan? I'm not sure if opengl-es is what would be required for 2d games. I've done a little research on this, and it's even far more daunting than Java itself. I can't even begin to figure out where to start with even just opengl, sans -es. My best guess would be that I need further knowledge in Java to continue with this, but even still, is it possible to learn concurrently with Java?

  • Bamboo to Build Specific SVN Revision

    - by Anton Gogolev
    Hi! Imagine there's a project in Bamboo with two build plans: Staging Deployment (SD) and Production Deployment (PD). Building SD checks out latest sources, builds them and deploys a web site to a staging server. Currently, PD does all the same, namely deploys the latest version of a web site to a production server. Clearly, this is not very good: I want to be able to deploy the same exact version of a web site that was previously deployed on a staging server, not the latest one. To illustrate: suppose we're at r101 in SVN repo. Clicking "Build SD" will deploy a web site version, say, 2.1.0.101 to staging server. Now we commit a breaking change and end up at r102. Now I want to deploy to a production server. If I hit "Build PD", Bamboo will happily check out r102 and build it, resulting in version 2.1.0.102 being deployed to a production server. What I want it to do, however, is to build and deploy a version which was previously built in an SD plan (that is, 2.1.0.101). Of course I can make SD plan to tag latest-successful build as tags/builds/latest, but I would rather have Bamboo itself handle that.

  • Error in Implementing WS Security web service in WebLogic 10.3

    - by Chris
    Hi, I am trying to develop a JAX WS web service with WS-Security features in WebLogic 10.3. I have used the ant tasks WSDLC, JWSC and ClientGen to generate skeleton/stub for this web service. I have two keystores namely WSIdentity.jks and WSTrust.jks which contains the keys and certificates. One of the alias of WSIdentity.jks is "ws02p". The test client has the following code to invoke the web service: SecureSimpleService service = new SecureSimpleService(); SecureSimplePortType port = service.getSecureSimplePortType(); List credProviders = new ArrayList(); CredentialProvider cp = new ClientBSTCredentialProvider( "E:\\workspace\\SecureServiceWL103\\keystores\\WSIdentity.jks", "webservice", "ws01p","webservice"); credProviders.add(cp); string endpointURL="http://localhost:7001/SecureSimpleService/SecureSimpleService"; BindingProvider bp = (BindingProvider)port; Map requestContext = bp.getRequestContext(); requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpointURL); requestContext.put(WSSecurityContext.CREDENTIAL_PROVIDER_LIST,credProviders); requestContext.put(WSSecurityContext.TRUST_MANAGER, new TrustManager() { public boolean certificateCallback(X509Certificate[] chain, int validateErr) { // Put some custom validation code in here. // Just return true for now return true; } }); SignResponse resp1 = new SignResponse(); resp1 = port.echoSignOnlyMessage("hello sign"); System.out.println("Result: " + resp1.getMessage()); When I trying to invoke this web servcie using this test client I am getting the error "Invalid signing policy" with the following stack trace: *[java] weblogic.wsee.security.wss.policy.SecurityPolicyArchitectureException: Invalid signing policy [java] at weblogic.wsee.security.wss.plan.SecurityPolicyBlueprintDesigner.verifyPolicy(SecurityPolicyBlueprintDesigner.java:786) [java] at weblogic.wsee.security.wss.plan.SecurityPolicyBlueprintDesigner.designOutboundBlueprint(SecurityPolicyBlueprintDesigner.java:136) Am I missing any configuration settings in WebLogic admin console or is it do with something else. Thanks in advance.

  • Increase Query Speed in PostgreSQL

    - by Anthoni Gardner
    Hello, First time posting here, but an avid reader. I am experiancing slow query times on my database (all tested locally thus far) and not sure how to go about it. The database itself has 44 tables and some of them tables have over 1 Million records (mainly the movies, actresses and actors tables). The table is made via JMDB using the flat files on IMDB. Also the SQL query that I am about to show is from that said program (that too experiances very slow search times). I have tried to include as much information as I can, such as the explain plan etc. "QUERY PLAN" "HashAggregate (cost=46492.52..46493.50 rows=98 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Append (cost=39094.17..46491.79 rows=98 width=46)" " - HashAggregate (cost=39094.17..39094.87 rows=70 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Seq Scan on movies (cost=0.00..39093.65 rows=70 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " Filter: (((title)::text ~~* '%Babe%'::text) AND ((title)::text !~~* '""%}'::text))" " - Nested Loop (cost=0.00..7395.94 rows=28 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Seq Scan on akatitles (cost=0.00..7159.24 rows=28 width=4)" " Output: akatitles.movieid, akatitles.language, akatitles.title, " Filter: (((title)::text ~~* '%Babe%'::text) AND ((title)::text !~~* '""%}'::text))" " - Index Scan using movies_pkey on movies (cost=0.00..8.44 rows=1 width=46)" " Output: public.movies.movieid, public.movies.title, public.movies.year, public.movies.imdbid" " Index Cond: (public.movies.movieid = akatitles.movieid)" SELECT * FROM ((SELECT DISTINCT title, movieid, year FROM movies WHERE title ILIKE '%Babe%' AND NOT (title ILIKE '"%}')) UNION (SELECT movies.title, movies.movieid, movies.year FROM movies INNER JOIN akatitles ON movies.movieid=akatitles.movieid WHERE akatitles.title ILIKE '%Babe%' AND NOT (akatitles.title ILIKE '"%}'))) AS union_tmp2; Returns 612 Rows in 9078ms Database backup (plain text) is 1.61GB It's a really complex query and I am not fully cognizant on it, like I said it was spat out by JMDB. Do you have any suggestions on how I can increase the speed ? Regards Anthoni

  • Created nested model setting a property on nested model before save

  • Using Oracle hint "FIRST_ROWS" to improve Oracle database performances

    - by bobetko
    I have a statement that runs on Oracle database server. The statement has about 5 joins and there is nothing unusual there. It looks pretty much like below: SELECT field1, field2, field3, ... FROM table1, table2, table3, table4, table5 WHERE table1.id = table2.id AND table2.id = table3.id AND ... table5.userid = 1 The problem (and what is interesting) is that statement for userid = 1 takes 1 second to return 590 records. Statement for userid = 2 takes around 30 seconds to return 70 records. I don't understand why is difference so big. It seems that different execution plan is chosen for statement with userid = 1 and different for userid = 2. After I implemented Oracle Hint FIRST_ROW, performance become significantly better. Both statements (for both ids 1 and 2) produce return in under 1 second. SELECT /*+ FIRST_ROWS */ field1, field2, field3, ... FROM table1, table2, table3, table4, table5 WHERE table1.id = table2.id AND table2.id = table3.id AND ... table5.userid = 1 Questions: 1) What are possible reasons for bad performance when userid = 2 (when hint is not used)? 2) Why would execution plan be different for one vs another statement (when hint is not used)? 3) Is there anything that I should be careful about when deciding to add this hint to my queries? Thanks

  • SQL SERVER 2008 JOIN hints

    - by Nai
    Hi all, Recently, I was trying to optimise this query UPDATE Analytics SET UserID = x.UserID FROM Analytics z INNER JOIN UserDetail x ON x.UserGUID = z.UserGUID Estimated execution plan show 57% on the Table Update and 40% on a Hash Match (Aggregate). I did some snooping around and came across the topic of JOIN hints. So I added a LOOP hint to my inner join and WA-ZHAM! The new execution plan shows 38% on the Table Update and 58% on an Index Seek. So I was about to start applying LOOP hints to all my queries until prudence got the better of me. After some googling, I realised that JOIN hints are not very well covered in BOL. Therefore... Can someone please tell me why applying LOOP hints to all my queries is a bad idea. I read somewhere that a LOOP JOIN is default JOIN method for query optimiser but couldn't verify the validity of the statement? When are JOIN hints used? When the sh*t hits the fan and ghost busters ain't in town? What's the difference between LOOP, HASH and MERGE hints? BOL states that MERGE seems to be the slowest but what is the application of each hint? Thanks for your time and help people! I'm running SQL Server 2008 BTW. The statistics mentioned above are ESTIMATED execution plans.

  • Repackaging Jasper-Reports into an application specific OSGi bundle, legal or not?

    - by Chris
    Hi, I wanted to ask (probably a silly) question regarding the packaging of existing open-source components as OSGi bundles (more specifically Jasper Reports). I have an application that I am converting from a monolithic jar-hell type architecture to something more moduler and OSGi is my weapon of choice. There are various modules I have in mind but one of the modules is a reporting module. My own reporting module will be a jar file containing my code that should reference a Jasper Reports bundle. Trouble is, Jasper reports depends on far far too many libraries and is quite monolithic in its own right. I therefore wish to build my own Jasper Reports bundle but this is where I start getting confused about the legality of repackaging. I don't plan to re-compile but I do plan to re-bundle removing known items that I do not require. Can anyone offer advice on whether I am permitted to repackage (not recompile or extend) open-source libraries into OSGi bundles without falling foul of 'derivative works' clause of LGPL? I noticed that Groovy seems to offer some monolithic jars that include all dependancies and actually goes so far as to re-arrange the packages of its dependancies so that there are no namespace conflicts. This seems to me to be a violation of the license but if anyone can reassure me that this is legal then I would feel safer about my less intrusive custom-bundling of Jasper reports. Thanks for your time, Chris

  • Difficulty setting ArrayList to java.sql.Blob to save in DB using hibernate

    - by me_here
    I'm trying to save a java ArrayList in a database (H2) by setting it as a blob, for retrieval later. If this is a bad approach, please say - I haven't been able to find much information on this area. I have a column of type Blob in the database, and Hibernate maps to this with java.sql.Blob. The code I'm struggling with is: Drawings drawing = new Drawings(); try { ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = null; oos = new ObjectOutputStream(bos); oos.writeObject(plan.drawingPane21.pointList); byte[] buff = bos.toByteArray(); Blob drawingBlob = null; drawingBlob.setBytes(0, buff); drawing.setDrawingObject(drawingBlob); } catch (Exception e){ System.err.println(e); } The object I'm trying to save into a blob (plan.drawingPane21.pointList) is of type ArrayList<DrawingDot>, DrawingDot being a custom class implementing Serializable. My code is failing on the line drawingBlob.setBytes(0, buff); with a NullPointerException. Help appreciated.

  • Project Architecture For Enhancing Legacy project.

    - by vijay.shad
    I am working on legacy project. Now the situation demands project to be divided into parts. What strategy I should follow to do this task. Description: The legacy project (A) is fully functional web application with almost well defined layers. But now i need to extend the project to a further enhancement. This project usage maven as build tool. But it is used only for dependency managements only. (project exported to war form inside eclipse). The new enhancement needs me to add new data table, new UI(jsp, css, js and images). What should be my strategy to enhance to application. My proposed design. I am planing to create two new projects Project B : Main Enhancement works will done in this project. Will have all layers like service layer, dao layer and UI layer in itself. And will be a web application in itself. Project C : Extract some common model and service code form project-A and create this project. This project will be added as dependency to both the projects. If my this approach is okay! Then i presume there will be problem be problem in deployment. These two projects will demand to deploy separately(currently tomcat is used). But I must deploy these two projects as one war. So, i need to have a plan to change the web.xml entries to have configurations for both projects. This will comes with some more complexities with project. What should be my design for the project? Does my plan sounds good.

  • How can I test this SQL Server performance Utility?

    - by Martin Smith
    As part of my MSc I need to do a three month project later this year. I have decided to do something which will likely be useful for me in the workplace and spend the time getting to understand SQL Server internals. The deliverable for this project will be a performance advisor looking at a variety of different rules. Some static such as finding redundant indexes, some more dynamic such as using XEvents to find outlying invocations of stored procedure execution times when certain parameters are passed. I am struggling to come up with a good way of testing this though. I can obviously design a "bad" database and a synthetic workload that my tool will pick up issues on but I also need to demonstrate that it has real world utility. Looking at the self tuning database literature it is common to use TPC benchmarks but I've had a look at the TPCC site and it looks very time consuming to implement and not that good a fit to my project's testing needs in any event (I would still be able to "rig" it by the decisions I made on indexing or physical architecture). Plan A would be to find willing beta tester(s) but in the event that isn't possible I will need a fallback plan. The best idea I have come up with so far is to use the various MS sample applications as examples of real world applications. e.g. http://msftdpprodsamples.codeplex.com/ http://www.asp.net/community/projects/ Does anyone have any better suggestions?

  • Impact of ordering of correlated subqueries within a projection

    - by Michael Petito
    I'm noticing something a bit unexpected with how SQL Server (SQL Server 2008 in this case) treats correlated subqueries within a select statement. My assumption was that a query plan should not be affected by the mere order in which subqueries (or columns, for that matter) are written within the projection clause of the select statement. However, this does not appear to be the case. Consider the following two queries, which are identical except for the ordering of the subqueries within the CTE: --query 1: subquery for Color is second WITH vw AS ( SELECT p.[ID], (SELECT TOP(1) [FirstName] FROM [Preference] WHERE p.ID = ID AND [FirstName] IS NOT NULL ORDER BY [LastModified] DESC) [FirstName], (SELECT TOP(1) [Color] FROM [Preference] WHERE p.ID = ID AND [Color] IS NOT NULL ORDER BY [LastModified] DESC) [Color] FROM Person p ) SELECT ID, Color, FirstName FROM vw WHERE Color = 'Gray'; --query 2: subquery for Color is first WITH vw AS ( SELECT p.[ID], (SELECT TOP(1) [Color] FROM [Preference] WHERE p.ID = ID AND [Color] IS NOT NULL ORDER BY [LastModified] DESC) [Color], (SELECT TOP(1) [FirstName] FROM [Preference] WHERE p.ID = ID AND [FirstName] IS NOT NULL ORDER BY [LastModified] DESC) [FirstName] FROM Person p ) SELECT ID, Color, FirstName FROM vw WHERE Color = 'Gray'; If you look at the two query plans, you'll see that an outer join is used for each subquery and that the order of the joins is the same as the order the subqueries are written. There is a filter applied to the result of the outer join for color, to filter out rows where the color is not 'Gray'. (It's odd to me that SQL would use an outer join for the color subquery since I have a non-null constraint on the result of the color subquery, but OK.) Most of the rows are removed by the color filter. The result is that query 2 is significantly cheaper than query 1 because fewer rows are involved with the second join. All reasons for constructing such a statement aside, is this an expected behavior? Shouldn't SQL server opt to move the filter as early as possible in the query plan, regardless of the order the subqueries are written?

  • Java remove HTML from String without regular expressions

  • Replace System.Net.Mail.MailMessage with manually created message and send it

    - by DEH
    I am trying to send emails that will bounce to a known mailbox. I plan to use VERP. Unfortunately the System.Net.Mail.MailMessage object does not allow me to precisely set the From: and Sender: headers within my email - it forces the values so that the resulting email contains the phrase 'on behalf of', and does not allow me fine control over the relevant mime headers. I therefore plan to manually write mime email messages directly to the pickup directory so that I can independently control the From and Sender headers. My dev box is a Vista box and therefore does not have an SMTP server. I would like to configure the dev box so that I have an SMTP server running on it. I can then turn off the SMTP server, write messages to the pickup dir, then turn on the SMPT server and see how the individual emails that I have written will behave (some delivered, some bounced to a bounce handler on a different email domain, as dictated by the Sender). Two questions: 1. Can anyone recommend an SMTP server that will monitor a pickup directory? 2. If I set headers as follows; From:[email protected]; Sender:[email protected] then the recipient will see the email as having come from [email protected] ( and won't see any reference to [email protected]), but if the mail bounces then the NDR will be sent to [email protected]). It's a real pain to have to do this, but I can't see any way of using System.Net.Mail.MailMessage without it messing up my headers.

  • Poor execution plans when using a filter and CONTAINSTABLE in a query

    - by Paul McLoughlin
    We have an interesting problem that I was hoping someone could help to shed some light on. At a high level the problem is as below: The following query executes quickly (1 second): SELECT SA.* FROM cg.SEARCHSERVER_ACTYS AS SA JOIN CONTAINSTABLE(CG.SEARCHSERVER_ACTYS, NOTE, 'reports') AS T1 ON T1.[Key]=SA.UNIQUE_ID but if we add a filter to the query, then it takes approximately 2 minutes to return: SELECT SA.* FROM cg.SEARCHSERVER_ACTYS AS SA JOIN CONTAINSTABLE(CG.SEARCHSERVER_ACTYS, NOTE, 'reports') AS T1 ON T1.[Key]=SA.UNIQUE_ID WHERE SA.CHG_DATE'19 Feb 2010' Looking at the execution plan for the two queries, I can see that in the second case there are two places where there are huge differences between the actual and estimated number of rows, these being: 1) For the FulltextMatch table valued function where the estimate is approx 22,000 rows and the actual is 29 million rows (which are then filtered down to 1670 rows before the join) and 2) For the index seek on the full text index, where the estimate is 1 row and the actual is 13,000 rows As a result of the estimates, the optimiser is choosing to use a nested loops join (since it assumes a small number of rows) hence the plan is inefficient. We can work around the problem by either (a) parameterising the query and adding an OPTION (OPTIMIZE FOR UNKNOWN) to the query or (b) by forcing a HASH JOIN to be used. In both of these cases the query returns in sub 1 second and the estimates appear reasonable. My question really is 'why are the estimates being used in the poorly performing case so wildly inaccurate and what can be done to improve them'? Statistics are up to date on the indexes on the indexed view being used here. Any help greatly appreciated.

  • SQL Server 2005, wide indexes, computed columns, and sargable queries

    - by luksan
    In my database, assume we have a table defined as follows: CREATE TABLE [Chemical]( [ChemicalId] int NOT NULL IDENTITY(1,1) PRIMARY KEY, [Name] nvarchar(max) NOT NULL, [Description] nvarchar(max) NULL ) The value for Name can be very large, so we must use nvarchar(max). Unfortunately, we want to create an index on this column, but nvarchar(max) is not supported inside an index. So we create the following computed column and associated index based upon it: ALTER TABLE [Chemical] ADD [Name_Indexable] AS LEFT([Name], 20) CREATE INDEX [IX_Name] ON [Chemical]([Name_Indexable]) INCLUDE([Name]) The index will not be unique but we can enforce uniqueness via a trigger. If we perform the following query, the execution plan results in a index scan, which is not what we want: SELECT [ChemicalId], [Name], [Description] FROM [Chemical] WHERE [Name]='[1,1''-Bicyclohexyl]-2-carboxylic acid, 4'',5-dihydroxy-2'',3-dimethyl-5'',6-bis[(1-oxo-2-propen-1-yl)oxy]-, methyl ester' However, if we modify the query to make it "sargable," then the execution plan results in an index seek, which is what we want: SELECT [ChemicalId], [Name], [Description] FROM [Chemical] WHERE [Indexable_Name]='[1,1''-Bicyclohexyl]-' AND [Name]='[1,1''-Bicyclohexyl]-2-carboxylic acid, 4'',5-dihydroxy-2'',3-dimethyl-5'',6-bis[(1-oxo-2-propen-1-yl)oxy]-, methyl ester' Is this a good solution if we control the format of all queries executed against the database via our middle tier? Is there a better way? Is this a major kludge? Should we be using full-text indexing?

  • Skip Checkout in Magento for a downloadable product

    - by Aaron Newton
    Hello Magento boffins. I am using Magento to build an eBooks site. For the release, we plan to have a number of free downloadable books. We were hoping that it would be possible to use the normal Magento 'catalog' functionality to add categories with products underneath. However, since these are free downloadable products, it doesn't really make sense to send users through the checkout when they try to download. Does anyone know of a way to create a free downloadable product which bypasses the checkout altogether? I have noticed that there is a 'free sample' option for downloadable products, but I would prefer not to use this if I can as I plan to use this field for its intended purpose when I add paid products. [EDIT] I have noticed that some of you have voted this question down for 'lack of question clarity'. For clarity, I want: to know if it is possible to create a downloadable product in Magento which doesn't require users to go through the usual checkout process (since it is free) and which is not the 'Free Sample' field of a downloadable product Unfortunately I don't think I can ask this any more eloquently. [/EDIT]

  • SQL Server 2008 - Shrinking the Transaction Log - Any way to automate?

    I went in and checked my Transaction log the other day and it was something crazy like 15GB. I ran the following code: USE mydb GO BACKUP LOG mydb WITH TRUNCATE_ONLY GO DBCC SHRINKFILE(mydb_log,8) GO Which worked fine, shrank it down to 8MB...but the DB in question is a Log Shipping Publisher, and the log is already back up to some 500MB and growing quick. Is there any way to automate this log shrinking, outside of creating a custom "Execute T-SQL Statement Task" Maintenance Plan Task, and hooking it on to my log backup task? If that's the best way then fine...but I was just thinking that SQL Server would have a better way of dealing with this. I thought it was supposed to shrink automatically whenever you took a log backup, but that's not happening (perhaps because of my log shipping, I don't know). Here's my current backup plan: Full backups every night Transaction log backups once a day, late morning (maybe hook the Log shrinking onto this...doesn't need to be shrank every day though) Or maybe I just run it once a week, after I run a full backup task? What do you all think?

  • Easiest RPC client method in PHP

    - by T.K.
    I've been asked to help a friend's company to bring up a web application. I have very limited time and I reluctantly accepted the request, at one condition. As most of the logic goes on in the back-end, I suggested that I would finish the complete back-end only, allowing a front-end developer to simply interface with my backend. I plan to do the back-end in Java EE or Python (with Pylons). It does not really matter at this point. I plan to have my back-end completely ready and unit-tested, so that my input will hardly be needed after my work is done. I know they have a PHP programmer, but as far as I could tell he is a real rookie. I want him to basically interface with my backend's services in the easiest possible way, with no way of him "stuffing" it up. It's basically a CRUD-only application. I could implement the backend as accessible through a webservice such as XML-RPC or SOAP. Even a RESTful API could be possible. However, my main objective is to make something that complete "noob" PHP programmer can easily interface with without getting confused. Preferably I do not even want to talk to him because I generally have an extremely busy schedule, and doing "support calls" is not something I am willing to do. Which approach should I choose? I would welcome any suggestions and inputs!

  • Sybase stored procedure - how do I create an index on a #table?

    - by DVK
    I have a stored procedure which creates and works with a temporary #table Some of the queries would be tremendously optimized if that temporary #table would have an index created on it. However, creating an index within the stored procedure fails: create procedure test1 as SELECT f1, f2, f3 INTO #table1 FROM main_table WHERE 1 = 2 -- insert rows into #table1 create index my_idx on #table1 (f1) SELECT f1, f2, f3 FROM #table1 (index my_idx) WHERE f1 = 11 -- "QUERY X" When I call the above, the query plan for "QUERY X" shows a table scan. If I simply run the code above outside the stored procedure, the messages show the following warning: Index 'my_idx' specified as optimizer hint in the FROM clause of table '#table1' does not exist. Optimizer will choose another index instead. This can be resolved when running ad-hoc (outside the stored procedure) by splitting the code above in two batches by addding "go" after index creation: create index my_idx on #table1 (f1) go Now, "QUERY X" query plan shows the use of index "my_idx". QUESTION: How do I mimique running the "create index" in a separate batch when it's inside the stored procedure? I can't insert a "go" there like I do with the ad-hoc copy above. P.S. If it matters, this is on Sybase 12.

  • Scrum - Responding to traditional RFPs

    - by Todd Charron
    Hi all, I've seen many articles about how to put together Agile RFP's and negotiating agile contracts, but how about if you're responding to a more traditional RFP? Any advice on how to meet the requirements of the RFP while still presenting an agile approach? A lot of these traditional RFP's request specific technical implementations, timelines, and costs, while also requesting exact details about milestones and how the technical solutions will be implemented. While I'm sure in traditional waterfall it's normal to pretend that these things are facts, it seems wrong to commit to something like this if you're an agile organization just to get through the initial screening process. What methods have you used to respond to more traditional RFP's? Here's a sample one grabbed from google, http://www.investtoronto.ca/documents/rfp-web-development.pdf Particularly, "3. A detailed work plan outlining how they expect to achieve the four deliverables within the timeframe outlined. Plan for additional phases of development." and "8. The detailed cost structure, including per diem rates for team members, allocation of hours between team members, expenses and other out of pocket disbursements, and a total upset price."

  • Postgre database ignoring created index ?!

    - by drasto
    I have an Postgre database and a table called my_table. There are 4 columns in that table (id, column1, column2, column3). The id column is primary key, there are no other constrains or indexes on columns. The table has about 200000 rows. I want to print out all rows which has value of column column2 equal(case insensitive) to 'value12'. I use this: SELECT * FROM my_table WHERE column2 = lower('value12') here is the execution plan for this statement(result of set enable_seqscan=on; EXPLAIN SELECT * FROM my_table WHERE column2 = lower('value12')): Seq Scan on my_table (cost=0.00..4676.00 rows=10000 width=55) Filter: ((column2)::text = 'value12'::text) I consider this to be to slow so I create an index on column column2 for better prerformance of searches: CREATE INDEX my_index ON my_table (lower(column2)) Now I ran the same select: SELECT * FROM my_table WHERE column2 = lower('value12') and I expect it to be much faster because it can use index. However it is not faster, it is as slow as before. So I check the execution plan and it is the same as before(see above). So it still uses sequential scen and it ignores the index! Where is the problem ?

  • My first MVVM application architecture setup

    - by 1110
    Ok, time is coming for my first WPF project :). I work before with Flex and PureMVC and I know how project setup is important in RIA's. I decided to work with MVVM. And decided to work with PRISM framework. Application is somethin like operating system. There will be 'shell' (parent for smaller applications). Smaller application I plan to make like modules. So I plan to design structure of project something like this. Module_A {view, viewModel, model, assets} // for example calculator Module_B {view, viewModel, model, assets} // notebook etc I read prism doc and I see that parrent for all this modules should be shell project, and this is my main question here. Parrent_Project {App.xaml, Bootstrapper.cs, Shell.xaml} Because this shell will be fullscreen with background images (like operating system), right click with some features. Is that ok to create folder structure like in modulesXYZ for Shell.xaml here? I want to start project with good structure so any advice is welcome. Thanks
