  • PHP developer wanting to learn python

    - by dclowd9901
    I'm pretty familiar at this point with PHP (Javascript, too), up to the point of OOP in PHP, and am looking to branch out my knowledge. I'm looking at Python next, but a lot of it is a bit alien to me as a PHP developer. I'm less concerned about learning the language itself. I'm positive there's plenty of good resources, documentation and libraries to help me get the code down. I'm less sure about the technical aspects of how to set up a dev environment, unit testing and other more mundane details that are very important, aid in rapid development, but aren't as widely covered. Are there any good resources out there for this?

  • How to access shared folders from file editors?

    - by Marchosius
    I am running a xampp server on one of my other computers, and when using the brows functionality from text editors like gedit, bluefish and Eclipse/Aptana studio I can access the shares I made for the sites running on the server. Even when I right click-edit with-application with the the file browser it does not open the file in the editor. How can get this to work without having to copy the file over from the share then edit and then upload again after I am done? Similar issue when trying to upload a file to hosting server direct from the file server I have with filezilla. with this I also need to copy the file over to my pc and then from there upload to the hosting server with filezilla. EDIT: For eclipse I found a build in functionality to do this. (new-remote system connection-Enter the access details) Nothing yet on FileZilla Hope my Question is clear

  • How to number nested ordered lists.

    - by Wes
    Is there any way through CSS to style nested ordered lists to display sub numbers? The idea is similar to using heading levels. However what I'd really like to see is the following. Note each of these subsections has text not just a title. This isn't a real example just some organisational stuff. Now I know I can use <h1>-<h6> but nested lists would be much clearer and allow for different indentation styling. Also it would be symentically correct. Note I don't think that <h1>-<h6> are correct in many ways as the name doesn't apply to the whole section. 1 Introduction. 1.1 Scope Blah Blah Blah Blah Blah Blah 1.2 Purpose Blah Blah Blah Blah Blah Blah 2 Cars Blah Blah Blah Blah Blah Blah 2.1 engines sub Blah Blah Blah sub Blah Blah Blah 2.2 Wheels ... ... 2.10.21 hub caps sub-sub Blah Blah Blah sub-sub Blah Blah Blah 2.10.21.1 hub cap paint sub-sub-sub Blah Blah Blah sub-sub-sub Blah Blah Blah 3 Planes 3.1 Commercial Airlines. ... ... 212 Glossary

  • Hosting multiple low traffic websites on ec2

    - by Niko Sams
    We have like 30 websites with almost no traffic (<~10 visits / day) which are currently hosted on a dedicated server. We are evaluating hosting on Amazon EC2 however I'm not sure how to do that properly. One (micro) instance per website is too expensive ~10 websites on one instance (using apache virtual hosts) make auto scaling impossible (or at least difficult) Or is cloud computing not suitable for such a usecase?

  • How to develop Online Shopping Portal Application using PHP ?

    - by Sarang
    I do not know PHP & I have to develop a Shopping Portal with following Definition : Scenario: Online Shopping Portal XYZ.com wants to create an online shopping portal for managing its registered customers and their shopping. The customers need to register themselves first before they do shopping using the shopping portal. However, everyone, whether registered or not, can view the various products along with the prices listed in the portal. The registered customers, after logging in, are allowed to place order for one or more products from the products listed in the portal. Once the order is placed, the customer gets a reference order number and the order status should be “order in process”. The customers can track their order using the given reference number. The management of XYZ.com should be able to modify the order status of a particular reference order number to “shipped” once the products are shipped to the shipping address entered by the customer at the time of placing the order. The Functionalities required are : Create the interface for the XYZ.com shopping portal using HTML/XHTML and CSS. Implement the client side validations using JavaScript. Create the tables using MySQL. Implement the functionality using the server side scripting language, PHP. Integrate all the above tasks and make the XYZ.com shopping portal functional. How do I develop this application with following proper steps of development ?

  • Why would someone want to take over control of my domain name?

    - by mike jones
    I was approached by a person wanting to help me set up a website. In order to do this he has requested that I allow him to transfer my domain name to his account, for easier management. I would retain the right of usage and he would pay the bill for maintaining the name. This sounds fishy, but I can't figure out what he hopes to gain if this is a scam. Is this a common practice among 'Administrative Contacts'?

  • Validating allowed characters or validating disallowed characters

    - by Tom
    I've always validated my user input based on a list of valid/allowed characters, rather than a list of invalid/disallowed characters (or simply no validation). It's just a habit I picked up, probably on this site and I've never really questioned it until now. It makes sense if you wish to, say, validate a phone number, or validate an area code, however recently I've realised I'm also validating input such as Bio Text fields, User Comments, etc. for which the input has no solid syntax. The main advantage has always seemed to be: Validating allowed chars reduces the risk of you missing a potentially malicious character, but increases the risk the of you not allowing a character which the user may want to use. The former is more important. But, providing I am correctly preventing SQL Injection (with prepared statements) and also escaping output, is there any need for this extra barrier of protection? It seems to me as if I am just allowing practically every character on the keyboard, and am forgetting to allow some common characters. Is there an accepted practice for this situation? Or am I missing something obvious? Thanks.

  • Problem with user generated content

    - by grasshopper
    In general, what do you think is better in regards to adding content to a site, to allow users to add content to the site and put a flag button to report it if it doesn't fit with the site, or should only I add the content and remove that option? It will be a small site but I don't know if I'll manage to scan the site constantly or deal with the flags and on the other hand I'm worried that the site wont move forward because there will be lot less content, thoughts?

  • Class Design and Structure Online Web Store

    - by Phorce
    I hope I have asked this in the right forum. Basically, we're designing an Online Store and I am designing the class structure for ordering a product and want some clarification on what I have so far: So a customer comes, selects their product, chooses the quantity and selects 'Purchase' (I am using the Facade Pattern - So subsystems execute when this action is performed). My class structure: < Order > < Product > <Customer > There is no inheritance, more Association < Order has < Product , < Customer has < Order . Does this structure look ok? I've noticed that I don't handle the "Quantity" separately, I was just going to add this into the "Product" class, but, do you think it should be a class of it's own? Hope someone can help.

  • Using json as database with EF, how can I link EF and the json file during DbContext initialization?

    - by blacai
    For a personal testing-project I am considering to create a SPA with the following technologies: ASP.NET MVC + EF + WebAPI + AngularJS. The project will make use of small amount of data, so I was thinking I could use just a .json file as storage. But I am not sure about how to proceed with the link between EF and the json file in the initialization of the DbContext. I found a stackoverflow related question: http://stackoverflow.com/questions/13899342/can-we-use-json-as-a-database I know the basics of edit files and store data inside. What I tried is to get the data from the json file in the initilizer method and create the objects one by one. This is more a doubt about how this works if I save/update an object in the dbcontext, do I need to go through all the elements and add/update it manually? Is it better to rewrite the complete file? According to this http://stackoverflow.com/questions/7895335/append-data-to-a-json-file-with-php it is not a good practice to use json/XML for data wich will be manipulated. Anyone has experience with anything similar? Is this a really bad idea and I should use another kind of data-storage?

  • Carpool logical architecture

    - by enrmarc
    I'm designing a carpool system (drivers can publish their routes and passengers can subscribe to them) with WebServices(axis2) and Android clients (ksoap2). I have been having problems with the logical architecture of the system and I wondered if this architecture is fine. And another question: for that architecture (if it is ok), how would be the packages structure? I suppose something like that: (In android) package org.carpool.presentation *All the activities here (and maybe mvc pattern) (In the server) package org.carpool.services *Public interfaces (for example: register(User user), publishRoute(Route route) ) package org.carpool.domain *Pojos (for example: User.java, Route.java, etc) package org.carpool.persistence *Dao Interface and implementation (jdbc or hibernate)

  • Design Application to "Actively" Invite Users (pretend they have privileges)

    - by user3086451
    I am designing an application where users message one another privately, and may send messages to any Entity in the database (an Entity may not have a user account yet, it is a professional database). I am not sure how to best design the database and the API to allow messaging unregistered users. The application should remain secure, and data only accessed by those with correct permissions. Messages sent to persons without user accounts serve as an invitation. The invited person should be able to view the message, act on it, and complete the user registration upon receiving an InviteMessage. In simple terms, I have: User misc user fields (email, pw, dateJoined) Entity (large professional dataset): personalDetails... user->User (may be null) UserMessage: sender->User recipient->User dateCreated messageContent, other fields..... InviteMessage: sender->User recipient->Entity expiringUrl inviteeEmail inviteePhone I plan to alert the user when selecting a recipient that is not registered yet, and inform that he may send the message as an invitation by providing email, phone where we can send the invitation. Invitations will have a unique, one-time-use URL, e.g. uuid.uuid4(). When accessed, the invitee will see the InviteMessage and details about completing his/her registration profile. When registration is complete, InviteMessage details to a new instance of UserMessage (to not lose their data), and assign it to the newly created User. The ability to interact with and invite persons who do not yet have accounts is a key feature of the application, and it seems better to separate the invitation from the private, app messages (easier to keep functionality separate, better if data model changes). Is this a reasonable, good design? If not, what would you suggest? Do you have any improvements? Am I correct to choose to create a separate endpoint for creating invitations via the API?

  • How do I go about hosting facebook apps that are picking speed?

    - by Karthik
    My situation is this. I coded in php and built a facebook app. After 3 days it has 13,000 users. I have my own server at hostmonster. It is a regular plan costing me about $70 per year. It has unlimited bandwidth. I did not anticipate hosting apps or that it could pick up so many users. Already 1 Gb of data was transferred in the last few days. I am planning to build a few more apps(around 10 - 20) and reach atleast a million users in total. Should I continue hosting on the same server or move to a VPS? I am a student and I don't have too much of a disposable income. So I want to move only if it is necessary. Right now it shows 1 Gb/infinity in data transfer. Any help/suggestions highly appreciated.

  • Should I implement slugs with my already fairly long URLs?

    - by Earlz
    I'm considering implementing slugs in my blog. My blog uses MongoDB. One of the side-effects of using MongoDB is that it uses relatively long hex string IDs. Example before: http://lastyearswishes.com/blog/view/5070f025d1f1a5760fdfafac after: http://lastyearswishes.com/blog/view/5070f025d1f1a5760fdfafac/improvements-on-barelymvc Of course, that's a relatively short title.. I have some longer ones, but intend to limit the maximum character limit for slugs to something reasonable. At what point does a URL become so long that it hurts SEO instead of improves it? In this case, should I leave my URLs alone, or add slugs?

  • An Unusual UpdatePanel

    - by João Angelo
    The code you are about to see was mostly to prove a point, to myself, and probably has limited applicability. Nonetheless, in the remote possibility this is useful to someone here it goes… So this is a control that acts like a normal UpdatePanel where all child controls are registered as postback triggers except for a single control specified by the TriggerControlID property. You could basically achieve the same thing by registering all controls as postback triggers in the regular UpdatePanel. However with this, that process is performed automatically. Finally, here is the code: public sealed class SingleAsyncTriggerUpdatePanel : WebControl, INamingContainer { public string TriggerControlID { get; set; } [TemplateInstance(TemplateInstance.Single)] [PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate ContentTemplate { get; set; } public override ControlCollection Controls { get { this.EnsureChildControls(); return base.Controls; } } protected override void CreateChildControls() { if (string.IsNullOrWhiteSpace(this.TriggerControlID)) throw new InvalidOperationException( "The TriggerControlId property must be set."); this.Controls.Clear(); var updatePanel = new UpdatePanel() { ID = string.Concat(this.ID, "InnerUpdatePanel"), ChildrenAsTriggers = false, UpdateMode = UpdatePanelUpdateMode.Conditional, ContentTemplate = this.ContentTemplate }; updatePanel.Triggers.Add(new SingleControlAsyncUpdatePanelTrigger { ControlID = this.TriggerControlID }); this.Controls.Add(updatePanel); } } internal sealed class SingleControlAsyncUpdatePanelTrigger : UpdatePanelControlTrigger { private Control target; private ScriptManager scriptManager; public Control Target { get { if (this.target == null) { this.target = this.FindTargetControl(true); } return this.target; } } public ScriptManager ScriptManager { get { if (this.scriptManager == null) { var page = base.Owner.Page; if (page != null) { this.scriptManager = ScriptManager.GetCurrent(page); } } return this.scriptManager; } } protected override bool HasTriggered() { string asyncPostBackSourceElementID = this.ScriptManager.AsyncPostBackSourceElementID; if (asyncPostBackSourceElementID == this.Target.UniqueID) return true; return asyncPostBackSourceElementID.StartsWith( string.Concat(this.target.UniqueID, "$"), StringComparison.Ordinal); } protected override void Initialize() { base.Initialize(); foreach (Control control in FlattenControlHierarchy(this.Owner.Controls)) { if (control == this.Target) continue; bool isApplicableControl = false; isApplicableControl |= control is INamingContainer; isApplicableControl |= control is IPostBackDataHandler; isApplicableControl |= control is IPostBackEventHandler; if (isApplicableControl) { this.ScriptManager.RegisterPostBackControl(control); } } } private static IEnumerable<Control> FlattenControlHierarchy( ControlCollection collection) { foreach (Control control in collection) { yield return control; if (control.Controls.Count > 0) { foreach (Control child in FlattenControlHierarchy(control.Controls)) { yield return child; } } } } } You can use it like this, meaning that only the B2 button will trigger an async postback: <cc:SingleAsyncTriggerUpdatePanel ID="Test" runat="server" TriggerControlID="B2"> <ContentTemplate> <asp:Button ID="B1" Text="B1" runat="server" OnClick="Button_Click" /> <asp:Button ID="B2" Text="B2" runat="server" OnClick="Button_Click" /> <asp:Button ID="B3" Text="B3" runat="server" OnClick="Button_Click" /> <asp:Label ID="LInner" Text="LInner" runat="server" /> </ContentTemplate> </cc:SingleAsyncTriggerUpdatePanel>

  • Fixing SharePoint 2010 Permission Problems on Windows 7

    - by Ricardo Peres
    I had a tough time trying to have SharePoint working perfectly on a Windows 7 development machine that was occasionally disconnected from the Active Directory (when I am home I must connect through a VPN). I mostly had problems with service applications such as User Profile, Managed Metadata, Business Connectivity Services and the like, and all I knew were cryptical messages such as “access denied” or “the service or application pool is not started”. I was sure that both the services and application pools were running under a domain account that had proper permissions on the SQL Server instance, and basically it was a fresh installation. Lots of people are having the same problem, apparently. After banging my head against the wall for several days, I remembered about farm (what I had) versus stand-alone (which I had never tried) installations. Bingo! Here’s what I did: I dropped all SharePoint databases and logins and reinstalled SP from scratch, only this time not in farm mode, but as stand-alone. After the SharePoint Configuration Wizard started, I cancelled it and started the Management Shell. I created the configuration database manually by using the New-SPConfigurationDatabase cmdlet where I specified a local account – something that the Configuration Wizard wouldn’t allow me to do. Then I restarted the Configuration Wizard and everything began working perfectly! Yes, I got some pre-configured service applications and also some content which I didn’t need, but I realized it was possible to drop and recreate everything the way I wanted to. All services and application pools are now running under local accounts, which is fine for my development needs. Really, Microsoft… I hope this will bring light to someone facing the same problems!

  • Renewing a SSL certificate with GoDaddy

    - by Flavien
    GoDaddy sells SSL certificates for $12 per year (the most basic one). I have bought one of those last year, and now is the time to renew. However they are now asking for $50 for the renewal (the $12 is apparently a discount). Is there a way to get the $12 price for a renewal. Is it going to work if I buy a new certificate at $12, and use the same host as the one I had before, or are they going to prevent me from doing that?
