  • Are today's general purpose languages at the right level of abstarction ?

    - by KeesDijk
    Today Uncle Bob Martin, a genuine hero, showed this video In this video Bob Martin claims that our programming languages are at the right level for our problems at this time. One of the reasons I get from this video as that he Bob Martin sees us detail managers and our problems are at the detail level. This is the first time I have to disagree with Bob Martin and was wondering what the people at programmers think about this. First there is a difference between MDA and MDE MDA in itself hasn't worked and I blame way to much formalisation at a level you can't formalize these kind of problems. MDE and MDD are still trying to prove themselves and in my mind show great promise. e.g. look at MetaEdit The detail still needs to be management in my mind, but you do so in one place (framework or generators) instead of at multiple places. Right for our kind of problems ? I think depends on what problems you look at. Do the current programming languages keep up with the current demands on time to market ? Are they good at bridging the business IT communication gap ? So what do you think ?

  • Inflector for .NET

    - by srkirkland
    I was writing conventions for FluentNHibernate the other day and I ran into the need to pluralize a given string and immediately thought of the ruby on rails Inflector.  It turns out there is a .NET library out there also capable of doing word inflection, originally written (I believe) by Andrew Peters, though the link I had no longer works.  The entire Inflector class is only a little over 200 lines long and can be easily included into any project, and contains the Pluralize() method along with a few other helpful methods (like Singularize(), Camelize(), Capitalize(), etc). The Inflector class is available in its entirety from my github repository https://github.com/srkirkland/Inflector.  In addition to the Inflector.cs class I added tests for every single method available so you can gain an understanding of what each method does.  Also, if you are wondering about a specific test case feel free to fork my project and add your own test cases to ensure Inflector does what you expect. Here is an example of some test cases for pluralize: TestData.Add("quiz", "quizzes"); TestData.Add("perspective", "perspectives"); TestData.Add("ox", "oxen"); TestData.Add("buffalo", "buffaloes"); TestData.Add("tomato", "tomatoes"); TestData.Add("dwarf", "dwarves"); TestData.Add("elf", "elves"); TestData.Add("mouse", "mice");   TestData.Add("octopus", "octopi"); TestData.Add("vertex", "vertices"); TestData.Add("matrix", "matrices");   TestData.Add("rice", "rice"); TestData.Add("shoe", "shoes"); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Pretty smart stuff.

  • StreamInsight and Reactive Framework Challenge

    In his blogpost Roman from the StreamInsight team asked if we could create a Reactive Framework version of what he had done in the post using StreamInsight.  For those who don’t know, the Reactive Framework or Rx to its friends is a library for composing asynchronous and event-based programs using observable collections in the .Net framework.  Yes, there is some overlap between StreamInsight and the Reactive Extensions but StreamInsight has more flexibility and power in its temporal algebra (Windowing, Alteration of event headers) Well here are two alternate ways of doing what Roman did. The first example is a mix of StreamInsight and Rx var rnd = new Random(); var RandomValue = 0; var interval = Observable.Interval(TimeSpan.FromMilliseconds((Int32)rnd.Next(500,3000))) .Select(i => { RandomValue = rnd.Next(300); return RandomValue; }); Server s = Server.Create("Default"); Microsoft.ComplexEventProcessing.Application a = s.CreateApplication("Rx SI Mischung"); var inputStream = interval.ToPointStream(a, evt => PointEvent.CreateInsert( System.DateTime.Now.ToLocalTime(), new { RandomValue = evt}), AdvanceTimeSettings.IncreasingStartTime, "Rx Sample"); var r = from evt in inputStream select new { runningVal = evt.RandomValue }; foreach (var x in r.ToPointEnumerable().Where(e => e.EventKind != EventKind.Cti)) { Console.WriteLine(x.Payload.ToString()); } This next version though uses the Reactive Extensions Only   var rnd = new Random(); var RandomValue = 0; Observable.Interval(TimeSpan.FromMilliseconds((Int32)rnd.Next(500, 3000))) .Select(i => { RandomValue = rnd.Next(300); return RandomValue; }).Subscribe(Console.WriteLine, () => Console.WriteLine("Completed")); Console.ReadKey();   These are very simple examples but both technologies allow us to do a lot more.  The ICEPObservable() design pattern was reintroduced in StreamInsight 1.1 and the more I use it the more I like it.  It is a very useful pattern when wanting to show StreamInsight samples as is the IEnumerable() pattern.

  • ASP.NET MVC CRUD Validation

    - by Ricardo Peres
    One thing I didn’t refer on my previous post on ASP.NET MVC CRUD with AJAX was how to retrieve model validation information into the client. We want to send any model validation errors to the client in the JSON object that contains the ProductId, RowVersion and Success properties, specifically, if there are any errors, we will add an extra Errors collection property. Here’s how: 1: [HttpPost] 2: [AjaxOnly] 3: [Authorize] 4: public JsonResult Edit(Product product) 5: { 6: if (this.ModelState.IsValid == true) 7: { 8: using (ProductContext ctx = new ProductContext()) 9: { 10: Boolean success = false; 11:  12: ctx.Entry(product).State = (product.ProductId == 0) ? EntityState.Added : EntityState.Modified; 13:  14: try 15: { 16: success = (ctx.SaveChanges() == 1); 17: } 18: catch (DbUpdateConcurrencyException) 19: { 20: ctx.Entry(product).Reload(); 21: } 22:  23: return (this.Json(new { Success = success, ProductId = product.ProductId, RowVersion = Convert.ToBase64String(product.RowVersion) })); 24: } 25: } 26: else 27: { 28: Dictionary<String, String> errors = new Dictionary<String, String>(); 29:  30: foreach (KeyValuePair<String, ModelState> keyValue in this.ModelState) 31: { 32: String key = keyValue.Key; 33: ModelState modelState = keyValue.Value; 34:  35: foreach (ModelError error in modelState.Errors) 36: { 37: errors[key] = error.ErrorMessage; 38: } 39: } 40:  41: return (this.Json(new { Success = false, ProductId = 0, RowVersion = String.Empty, Errors = errors })); 42: } 43: } As for the view, we need to change slightly the onSuccess JavaScript handler on the Single view: 1: function onSuccess(ctx) 2: { 3: if (typeof (ctx.Success) != 'undefined') 4: { 5: $('input#ProductId').val(ctx.ProductId); 6: $('input#RowVersion').val(ctx.RowVersion); 7:  8: if (ctx.Success == false) 9: { 10: var errors = ''; 11:  12: if (typeof (ctx.Errors) != 'undefined') 13: { 14: for (var key in ctx.Errors) 15: { 16: errors += key + ': ' + ctx.Errors[key] + '\n'; 17: } 18:  19: window.alert('An error occurred while updating the entity: the model contained the following errors.\n\n' + errors); 20: } 21: else 22: { 23: window.alert('An error occurred while updating the entity: it may have been modified by third parties. Please try again.'); 24: } 25: } 26: else 27: { 28: window.alert('Saved successfully'); 29: } 30: } 31: else 32: { 33: if (window.confirm('Not logged in. Login now?') == true) 34: { 35: document.location.href = '<% 1: : FormsAuthentication.LoginUrl %>?ReturnURL=' + document.location.pathname; 36: } 37: } 38: } The logic is as this: If the Edit action method is called for a new entity (the ProductId is 0) and it is valid, the entity is saved, and the JSON results contains a Success flag set to true, a ProductId property with the database-generated primary key and a RowVersion with the server-generated ROWVERSION; If the model is not valid, the JSON result will contain the Success flag set to false and the Errors collection populated with all the model validation errors; If the entity already exists in the database (ProductId not 0) and the model is valid, but the stored ROWVERSION is different that the one on the view, the result will set the Success property to false and will return the current (as loaded from the database) value of the ROWVERSION on the RowVersion property. On a future post I will talk about the possibilities that exist for performing model validation, stay tuned!

  • Web.config WordPress rewrite rules next to Magento

    - by Flo
    I've installed Magento on IIS in folder: E:\mydomain\wwwroot (I already have it all running correctly). I have no deeper folder magento, I placed all files directly in the wwwroot folder, so: wwwroot\app wwwroot\downloader wwwroot\errors wwwroot\includes etc... UPDATE: since I'm on IIS my .htaccess is ignored completely and my web.config rules are used instead. Here's my web.config in folder e:\mydomain\wwwroot: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="Magento SEO: remove index.php from URL"> <match url="^(?!index.php)([^?#]*)(\\?([^#]*))?(#(.*))?" /> <conditions> <add input="{URL}" pattern="^/(media|skin|js)/" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" /> </conditions> <action type="Rewrite" url="index.php/{R:0}" /> </rule> </rules> </rewrite> </system.webServer> </configuration> Next, I wanted to install WordPress. I unzipped all files in folder e:\mydomain\wwwroot\wordpress Browsed to www.mydomain.com/wordpress/wp-admin/install.php, where I configured everything for my database. Everything was installed correctly. I then navigate to http://www.mydomain.com/wordpress/wp-login.php where I type my credentials. I seem to be logged in and am redirected to http://www.mydomain.com/wordpress/wp-admin/ But there I receive an empty page. I enabled detailed error message in IIS following this article: http://www.iis.net/learn/troubleshoot/diagnosing-http-errors/how-to-use-http-detailed-errors-in-iis I also checkec with Fiddler and see that I receive a 500 error: GET /wordpress/wp-admin/ HTTP/1.1 Host: www.mydomain.com Connection: keep-alive Cache-Control: max-age=0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36 Referer: http://www.mydomain.com/wordpress/wp-login.php Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8,nl;q=0.6 Cookie: wordpress_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7C2d8edb4fc6618f290fadb49b035cad31; wordpress_test_cookie=WP+Cookie+check; wordpress_logged_in_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7Cbf822163926b8b8df16d0f1fefb6e02e HTTP/1.1 500 Internal Server Error Content-Type: text/html Server: Microsoft-IIS/7.5 X-Powered-By: PHP/5.4.14 X-Powered-By: ASP.NET Date: Sun, 06 Oct 2013 12:56:03 GMT Content-Length: 0 My WordPress web.config in folder e:\mydomain\wwwroot\wordpress contains: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="wordpress" patternSyntax="Wildcard"> <match url="*"/> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/> </conditions> <action type="Rewrite" url="index.php"/> </rule></rules> </rewrite> </system.webServer> </configuration> I also want my WordPress articles to be available on www.mydomain.com/blog instead of www.mydomain.com/wordpress Ofcourse my admin links for Magento and Wordpress should also work.

  • Bit-Twiddling in SQL

    - by Mike C
    Someone posted a question to the SQL Server forum the other day asking how to count runs of zero bits in an integer using SQL. Basically the poster wanted to know how to efficiently determine the longest contiguous string of zero-bits (known as a run of bits) in any given 32-bit integer. Here are a couple of examples to demonstrate the idea: Decimal = Binary = Zero Run 999,999,999 decimal = 00 111011 1 00 11010 11 00 1 00 1 11111111 binary = 2 contiguous zero bits 666,666,666 decimal = 00100111 10111100...(read more)

  • java.util.ConcurrentModificationException when serializing non thread-safe maps

    - by [email protected]
    We have got some questions related to exceptions thrown during a map serialization like the following one (in this example, for a LRUMap): java.util.ConcurrentModificationExceptionat org.apache.commons.collections.SequencedHashMap$OrderedIterator.next(Unknown Source)at org.apache.commons.collections.LRUMap.writeExternal(Unknown Source)at java.io.ObjectOutputStream.writeExternalData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java(Inlined CompiledCode))at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java(Inlined CompiledCode))at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java(Inlined CompiledCode))at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java(Compiled Code))at com.tangosol.util.ExternalizableHelper.writeSerializable(ExternalizableHelper.java(InlinedCompiled Code))at com.tangosol.util.ExternalizableHelper.writeObjectInternal(ExternalizableHelper.java(Compiled Code))at com.tangosol.util.ExternalizableHelper.serializeInternal(ExternalizableHelper.java(Compiled Code))at com.tangosol.util.ExternalizableHelper.toBinary(ExternalizableHelper.java(InlinedCompiled Code))at com.tangosol.util.ExternalizableHelper.toBinary(ExternalizableHelper.java(InlinedCompiled Code))at com.tangosol.coherence.servlet.TraditionalHttpSessionModel$OptimizedHolder.serializeValue(TraditionalHttpSessionModel.java(Inlined Compiled Code))at com.tangosol.coherence.servlet.TraditionalHttpSessionModel$OptimizedHolder.getBinary(TraditionalHttpSessionModel.java(Compiled Code)) This is caused because LRUMap is not thread safe, so if another thread is modifying the content of that same map while serialization is in progress, then the ConcurrentModificationException will be thrown. Also, the map must be synchronized. Other structures like java.util.HashMap are not thread safe too. To avoid this kind of problems, it is recommended to use a thread-safe and synchronized map such as java.util.Map, java.util.Hashtable or com.tangosol.util.SafeHashMap. You may also need to use the synchronizedMap(Map) method from Class java.util.Collections.

  • Implicit and Explicit implementations for Multiple Interface inheritance

    Following C#.NET demo explains you all the scenarios for implementation of Interface methods to classes. There are two ways you can implement a interface method to a class. 1. Implicit Implementation 2. Explicit Implementation. Please go though the sample. using System;   namespace ImpExpTest { class Program { static void Main(string[] args) { C o3 = new C(); Console.WriteLine(o3.fu());   I1 o1 = new C(); Console.WriteLine(o1.fu());   I2 o2 = new C(); Console.WriteLine(o2.fu());   var o4 = new C(); //var is considered as C Console.WriteLine(o4.fu());   var o5 = (I1)new C(); //var is considered as I1 Console.WriteLine(o5.fu());   var o6 = (I2)new C(); //var is considered as I2 Console.WriteLine(o6.fu());   D o7 = new D(); Console.WriteLine(o7.fu());   I1 o8 = new D(); Console.WriteLine(o8.fu());   I2 o9 = new D(); Console.WriteLine(o9.fu()); } }   interface I1 { string fu(); }   interface I2 { string fu(); }   class C : I1, I2 { #region Imicitly Defined I1 Members public string fu() { return "Hello C"; } #endregion Imicitly Defined I1 Members   #region Explicitly Defined I1 Members   string I1.fu() { return "Hello from I1"; }   #endregion Explicitly Defined I1 Members   #region Explicitly Defined I2 Members   string I2.fu() { return "Hello from I2"; }   #endregion Explicitly Defined I2 Members }   class D : C { #region Imicitly Defined I1 Members public string fu() { return "Hello from D"; } #endregion Imicitly Defined I1 Members } }.csharpcode, .csharpcode pre{ font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/}.csharpcode pre { margin: 0em; }.csharpcode .rem { color: #008000; }.csharpcode .kwrd { color: #0000ff; }.csharpcode .str { color: #006080; }.csharpcode .op { color: #0000c0; }.csharpcode .preproc { color: #cc6633; }.csharpcode .asp { background-color: #ffff00; }.csharpcode .html { color: #800000; }.csharpcode .attr { color: #ff0000; }.csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em;}.csharpcode .lnum { color: #606060; }Output:-Hello C Hello from I1 Hello from I2 Hello C Hello from I1 Hello from I2 Hello from D Hello from I1 Hello from I2 span.fullpost {display:none;}

  • Learning django by example source code (not examples)

    - by Bryce
    I'm seeking a nice complete open source django application to study and learn best practices from, or even use as a template. The tutorials only go so far, and django is super flexible which can lead one to paining themselves into a corner. Ideally such a template / example would: Ignore django admin, and implement full CRUD outside the admin. Be built like a large application in terms of best practices and patterns. Have a unit test Use at least one package (e.g. twitter integration or threaded comments) Implement some AJAX or Comet See also: Learning Django by example

  • T4Toolbox and Visual Studio 2010

    - by Ben Griswold
    I’ve been using the T4Toolbox to help generate my ASP.NET MVC models and scaffolding for a while now.  Another developer tried using my generator project last week and ran into troubles due to a breaking change around the RenderCore() and TransformText() methods in support for VS 2010.  If you upgraded to the latest version of T4Toolbox and receive a build error similar to the following, you are probably in the same boat: GeneratedTextTransformation.[Template].RenderCore(): no suitable method found to override We took the easy way out.  I had him uninstall the latest version of T4Toolbox and install version 9.7.25.1 which my templates were initially coded against.  For now, that worked great, but it sounds like I’ll be doing some rework of the 20+ templates in my project to support Visual Studio 2010 when we migrate later this month.

  • htaccess code for maintenance page redirect

    - by Force Flow
    I set up a maintenance page that I could enable through an htaccess file. The html file is located in a folder called "maintenance". The html file has some images in it. However, visitors to the page see no images, even though I added a line to allow them. If I try to visit an image in the browser directly, it redirects to the maintenance.htm page. Am I missing something? # Redirects visitors to maintenance page except for specific IP addresses # uncomment lines when redirecting visitors to maintenance page; comment when done. # Also see the section on "redirects visitors from maintenance page to homepage" # #RewriteCond %{REMOTE_ADDR} !^127.0.0.1$ #RewriteCond %{REMOTE_ADDR} !^111.111.111.111$ RewriteCond %{REQUEST_URI} !/maintenance/maintenance\.htm$ [NC] RewriteCond %{REQUEST_URI} !\.(jpg|jpeg|png|gif|css|ico)$ [NC] RewriteRule ^(.*)$ /maintenance/maintenance.htm [R=302,L] # # end redirects visitors to maintenance page # Redirects visitors from maintenance page to homepage # comment lines when redirecting visitors to maintenance page; uncomment when done # #Redirect 301 /maintenance/maintenance.htm / # # end redirects visitors from maintenance page to homepage

  • How to code Umbraco XSLT to retrieve Nodes from unrelated tree

    - by Phil.Wheeler
    I have an Umbraco site for personal use that I want to also use as a blog. I'm trying to put together the XSLT to grab the top three posts from the nodes in the Blog tree (node id = 1063) and display these on a tab page that is incorporated into the front page. The following image illustrates the node hierarchy: With my extremely limited appreciation of XSLT, I'm unable to grab the node ID of the "Blog" id and take the 3 pages below that to display in the "Top Posts" part of my site which is found under the "Frontpage Tabs" node. All the examples I find work with the "current page", which is typically the top-level node, "Personal Site". How should I accomplish this?

  • How do I let programmers know something useful?

    - by Shane
    Quite often I go through pain to discover how to do something useful, in this case how to get PHP running on Google App Engine without the 'resin.jar too big' problem, but I have nowhere to let people know. In this particular case, the web answers were incomplete, outdated or plain wrong. I could create a blog, but it's overkill. I just want let programmers know a quick solution/approach. I'm not sure it's the done thing to ask a question and then answer it. In short, it'd be nice to be able to just dump a sort of combined question/answer/snippet, then let others comment as usual, shoot it down, like it, whatever. How do the rest of you approach this? Cheers, Shane

  • what does AngleVectors method in quake 3 source code does

    - by kypronite
    I just downloaded quake 3 for learning purposes. I know some of some linear algebra(basic vector math ie: dot,cross product). However I can't decipher what below method does, I know what is yaw,pitch and roll. But I can't connect these with vector. Worse, I'm not sure this fall under what math 'category', so I don't really know how to google. Hence the question here. Anyone? void AngleVectors( const vec3_t angles, vec3_t forward, vec3_t right, vec3_t up) { float angle; static float sr, sp, sy, cr, cp, cy; // static to help MS compiler fp bugs angle = angles[YAW] * (M_PI*2 / 360); sy = sin(angle); cy = cos(angle); angle = angles[PITCH] * (M_PI*2 / 360); sp = sin(angle); cp = cos(angle); angle = angles[ROLL] * (M_PI*2 / 360); sr = sin(angle); cr = cos(angle); if (forward) { forward[0] = cp*cy; forward[1] = cp*sy; forward[2] = -sp; } if (right) { right[0] = (-1*sr*sp*cy+-1*cr*-sy); right[1] = (-1*sr*sp*sy+-1*cr*cy); right[2] = -1*sr*cp; } if (up) { up[0] = (cr*sp*cy+-sr*-sy); up[1] = (cr*sp*sy+-sr*cy); up[2] = cr*cp; } } ddddd

  • Strategy to find bottleneck in a network

    - by Simone
    Our enterprise is having some problem when the number of incoming request goes beyond a certain amount. To make things simpler, we have N websites that uses, amongst other, a local web service. This service is hosted by IIS, and it's a .NET 4.0 (C#) application executed in a farm. It's REST-oriented, built around OpenRasta. As already mentioned, by stress testing it with JMeter, we've found that beyond a certain amount of request the service's performance drop. Anyway, this service is, amongst other, a client itself of other 3 distinct web services and also a client for a DB server, so it's not very clear what really is the culprit of this abrupt decay. In turn, these 3 other web services are installed in our farm too, and client of other DB servers (and services, possibly, that are out of my team control). What strategy do you suggest to try to locate where the bottleneck(s) are? Do you have any high-level suggestions?

  • Compiling C++ Source code?iostream.h not found?

    - by gabriel
    I do not want to discuss about C++ or any programming language!I just want to know what am i doing wrong with linux ubuntu about compiling helloworld.cpp! I am learning C++ so my steps are: open hello.cpp in vim and write this #include <iostream.h> int main() { cout << "Hello World!\n";` return 0; } So, after that i tried in the terminal this g++ hello.cpp AND the output is hello.cpp:1:22: fatal error: iostream.h: No such file or directory compilation terminated. What do you suggest? Any useful step by step guide for me?Thanks!
