  • What could be my path? Networking, programming, or something else?

    - by momong
    Well first and foremost, I would like to give my brief description: I was an aviation student but I didn't pursue that path because I lost my interest. Now I'm an I.T. student and currently stopped schooling because of confusion. I don't know which path I should choose: could it be programming or networking? Someone told me that on networking the money is easy, the job is easy. Others told me that programming is best suited for me because I'm very skilled and excellent at figures. I want to chose networking, but I can't find my passion for it, my mind tells me but my heart doesn't... and on programming, I don't know which language I should pick or if I like it or not. A good mentor, even if only online, would be a very big plus to me, but I don't think if there are many who could spent their time on teaching a nobody... but I'm very eager to learn. My real passion is gaming! I want to work in the gaming industry, I want to be a man behind those games! I've been a gamer freak since birth. But I don't know how to get in to that industry. I don't know what to do. I don't know which path would really suit me. Sorry if some of you find this a pointless question, but please bear with me, this could be the turn of my life.

  • Sub routing in a SPA site

    - by Anders
    I have a SPA site that I'm working on, I have a requirement that you can have subroutes for a page view model. Im currently using this 'pattern' for the site MyApp.FooViewModel = MyApp.define({ meta: { query: MyApp.Core.Contracts.Queries.FooQuery, title: "Foo" }, init: function (queryResult) { }, prototype: { } }); In the master view model I have a route table this.navigation(new MyApp.RoutesViewModel({ Home: { model: MyApp.HomeViewModel, route: String.empty }, Foo: { model: MyApp.FooViewModel } })); The meta object defines which query should populate the top level view model when its invoked through sammyjs, this is all fine but it does not support sub routing My plan is to change the meta object so that it can (optional offcourse) look like this meta: { query: MyApp.Core.Contracts.Queries.FooQuery, title: "Foo", route: { barId: MyApp.BarViewModel } } When sammyjs detects a barId in the query string the Barmodel will be executed and populated through its own meta object. Is this a good design?

  • How important is responsive web design?

    - by Daniel
    I've heard many different opinions regarding the pros and cons of responsive web design recently and was wondering whether it was necessary for small businesses that target small geographical areas to implement it? Some sub-questions I have relating to this include: Is it better to use responsive web design as opposed to having separate code utilized for different dimensions/devices? Can it affect SEO (positively or negatively)? What are the main problems I could run into when optimizing a website for a business using this design method?

  • Best practices for web page styling with CSS?

    - by adifire
    I have a website to design. I have information on how the page should look and interact. The problem is I'm not good in front-end design, and have put many many hours to get the hang of the stuff. Currently, i am getting the CSS from sample sites in github and use them to style my site, which seems to be Not a ethical way. Question: how do you style webpages? Are there some really good tools? I would be deeply appreciated if a detailed answer will bee provided or link to wiki will work as well.

  • How to add new filters to CAML queries in SharePoint 2007

    - by uruit
      Normal 0 21 false false false ES-UY X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} One flexibility SharePoint has is CAML (Collaborative Application Markup Language). CAML it’s a markup language like html that allows developers to do queries against SharePoint lists, it’s syntax is very easy to understand and it allows to add logical conditions like Where, Contains, And, Or, etc, just like a SQL Query. For one of our projects we have the need to do a filter on SharePoint views, the problem here is that the view it’s a list containing a CAML Query with the filters the view may have, so in order to filter the view that’s already been filtered before, we need to append our filters to the existing CAML Query. That’s not a trivial task because the where statement in a CAML Query it’s like this: <Where>   <And>     <Filter1 />     <Filter2 />   </And> </Where> If we want to add a new logical operator, like an OR it’s not just as simple as to append the OR expression like the following example: <Where>   <And>     <Filter1 />     <Filter2 />   </And>   <Or>     <Filter3 />   </Or> </Where> But instead the correct query would be: <Where>   <Or>     <And>       <Filter1 />       <Filter2 />     </And>     <Filter3 />   </Or> </Where> Notice that the <Filter# /> tags are for explanation purpose only. In order to solve this problem we created a simple component, it has a method that receives the current query (could be an empty query also) and appends the expression you want to that query. Example: string currentQuery = @“ <Where>    <And>     <Contains><FieldRef Name='Title' /><Value Type='Text'>A</Value></Contains>     <Contains><FieldRef Name='Title' /><Value Type='Text'>B</Value></Contains>   </And> </Where>”; currentQuery = CAMLQueryBuilder.AppendQuery(     currentQuery,     “<Contains><FieldRef Name='Title' /><Value Type='Text'>C</Value></Contains>”,     CAMLQueryBuilder.Operators.Or); The fist parameter this function receives it’s the actual query, the second it’s the filter you want to add, and the third it’s the logical operator, so basically in this query we want all the items that the title contains: the character A and B or the ones that contains the character C. The result query is: <Where>   <Or>      <And>       <Contains><FieldRef Name='Title' /><Value Type='Text'>A</Value></Contains>       <Contains><FieldRef Name='Title' /><Value Type='Text'>B</Value></Contains>     </And>     <Contains><FieldRef Name='Title' /><Value Type='Text'>C</Value></Contains>   </Or> </Where>             The code:   First of all we have an enumerator inside the CAMLQueryBuilder class that has the two possible Options And, Or. public enum Operators { And, Or }   Then we have the main method that’s the one that performs the append of the filters. public static string AppendQuery(string containerQuery, string logicalExpression, Operators logicalOperator){   In this method the first we do is create a new XmlDocument and wrap the current query (that may be empty) with a “<Query></Query>” tag, because the query that comes with the view doesn’t have a root element and the XmlDocument must be a well formatted xml.   XmlDocument queryDoc = new XmlDocument(); queryDoc.LoadXml("<Query>" + containerQuery + "</Query>");   The next step is to create a new XmlDocument containing the logical expression that has the filter needed.   XmlDocument logicalExpressionDoc = new XmlDocument(); logicalExpressionDoc.LoadXml("<root>" + logicalExpression + "</root>"); In these next four lines we extract the expression from the recently created XmlDocument and create an XmlElement.                  XmlElement expressionElTemp = (XmlElement)logicalExpressionDoc.SelectSingleNode("/root/*"); XmlElement expressionEl = queryDoc.CreateElement(expressionElTemp.Name); expressionEl.InnerXml = expressionElTemp.InnerXml;   Below are the main steps in the component logic. The first “if” checks if the actual query doesn’t contains a “Where” clause. In case there’s no “Where” we add it and append the expression.   In case that there’s already a “Where” clause, we get the entire statement that’s inside the “Where” and reorder the query removing and appending elements to form the correct query, that will finally filter the list.   XmlElement whereEl; if (!containerQuery.Contains("Where")) { queryDoc.FirstChild.AppendChild(queryDoc.CreateElement("Where")); queryDoc.SelectSingleNode("/Query/Where").AppendChild(expressionEl); } else { whereEl = (XmlElement)queryDoc.SelectSingleNode("/Query/Where"); if (!containerQuery.Contains("<And>") &&                 !containerQuery.Contains("<Or>"))        {              XmlElement operatorEl = queryDoc.CreateElement(GetName(logicalOperator)); XmlElement existingExpression = (XmlElement)whereEl.SelectSingleNode("/Query/Where/*"); whereEl.RemoveChild(existingExpression);                 operatorEl.AppendChild(existingExpression);               operatorEl.AppendChild(expressionEl);                 whereEl.AppendChild(operatorEl);        }        else        {              XmlElement operatorEl = queryDoc.CreateElement(GetName(logicalOperator)); XmlElement existingOperator = (XmlElement)whereEl.SelectSingleNode("/Query/Where/*");                 whereEl.RemoveChild(existingOperator);               operatorEl.AppendChild(existingOperator);               operatorEl.AppendChild(expressionEl);                 whereEl.AppendChild(operatorEl);         }  }  return queryDoc.FirstChild.InnerXml }     Finally the GetName method converts the Enum option to his string equivalent.   private static string GetName(Operators logicalOperator) {       return Enum.GetName(typeof(Operators), logicalOperator); }        This component helped our team a lot using SharePoint 2007 and modifying the queries, but now in SharePoint 2010; that wouldn’t be needed because of the incorporation of LINQ to SharePoint. This new feature enables the developers to do typed queries against SharePoint lists without the need of writing any CAML code.   Normal 0 21 false false false ES-UY X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-fareast-language:EN-US;} Post written by Sebastian Rodriguez - Portals and Collaboration Solutions @ UruIT

  • Technologie Roadmap: Portlet JSR286 vs Widget/Gadget

    - by Aerosteak
    Hello IBM got me confused (again). For many years IBM have been pushing for Portlet Containers with the JSR 168 and later the JSR 286 Specification. 2008-2009, IBM the Lotus division introduced the iWidget Specification. Based on my reading, it is a more dynamic and lightweight version of the Portlets, close to Google Gadget. It uses a different paradigm than Porlet while providing the same features. A major differentiator with this kind of client side technologies is that you don’t need a big and costly Portal infrastructure. To not fall in the ‘It depends on needs’ discussions, let consider the following: * New company, no legacy portlet, no portal in place. What are your thoughts on this?

  • How can I upload to a PPA without .changes file?

    - by espectalll123
    So, I'm developing an app for the Ubuntu Showdown, and as quickly is still very buggy (I had problems using it), I decided to do my app entirely from scratch, using Python/GTK+3. I've done my app and I've just packaged it just using only fakebuild dkpg-deb --build. The problem is that I can't create a .source file, as I don't have a changelog file and the debian folder cannot be used in debuild, as is uncorrectly organized.

  • Will it hurt my website's SEO friendliness if I host a french targetted website at, let's say, godaddy.com?

    - by Suraj
    Hi guys, I have read that the server location is important for a website to be SEO friendly. I am planning to build a website from scratch which is targetted mainly to french audience (in france), but I am planning to host the web site at godaddy.com. My concern is will it hurt the website SEO friendliness? Or do you recommend me to host the website in france itself? I have also read that I need to have a static IP Address. If it's true, can anyone explain me for what reason? Can anyone suggest me some good web hosting companies, prefereable in france? Thanks in advance!

  • The University with the best Computer Science degree?

    - by Shinnok
    Which University provides the best Computer Science degree in your opinion(non US Universities welcomed too)? I do realize that you most probably didn't attend more then one University so you can't really provide a truly insightful opinion on several institutions, but what you can do instead, is describe the one you attended and outline it's strengths and weaknesses. What do i mean by the best is essentially the University that upon graduation and given a subject's assumed reasonable level of passion and interest in the field, one can trust upon the fact he was at least exposed to the best and most deep, correct and up to date courses on Programming, Operating Systems, Internet and Computer Technology overall. We have all heard of recent horror stories in Computer Science teaching, thus an exposure the best of the best, essentially the University you would grant your children to if they were to be interested into this field, would be a great thing.

    SO I'm building an application for uploading files. We're paying scientists to contribute information on pests, diseases and bugs (for Plants). We need the ability to drag and drop a file to upload it. The question becomes since the users will be authicentated and setup by us, will it be necessarcy to include a virus scanner to prevent the uploading and insertition of malicious files. How important is this?

  • How do people deal with Android fragmentation?

    - by Bill
    I've spent the past few years working on iOS apps, and I'm now giving some serious consideration to creating an Android port of one of my apps. I'm sure that complaints about fragmentation are a frustrating cliche to experienced Android programmers, but as an iOS programmer, I'm quite honestly overwhelmed by the number of configurations and devices that my app might end up running on. There are literally thousands of Android devices in the wild, but I know there are successful Android developers in the world and I know they're not testing or developing for thousands of different devices. So how can a relatively small company deal with fragmentation? Is it possible to pick the five or six most popular devices, focus on those and prevent the app from being installed on any other devices? Are there any other strategies for practically dealing with the number of different configurations an app will face?

  • PHP usage outside the web?

    - by Anto
    As you probably are aware, PHP is not only usable for web programming, but also desktop programming. It even has things such as GTK bindings. Do you have any examples of places where PHP is actually used outside web programming for anything more than just very trivial programs? Do you know of any desktop program which uses PHP to some extent (e.g. as Python could be used in a C program)? Note: I don't program in PHP myself, I'm just curious

  • What steps should I follow to start developing website applications?

    - by Oscar Mederos
    Hello, I've been developing desktop applications for about 4 years, using .NET, C++, C, and a little of Python. I've covered lots of topics while developing my applications, and even web technologies (cookies, GET/POST methods, when programming some scrapers/crawlers). I've been always waiting to start developing websites, preferably using PHP + MySQL, although other advises will be welcomed to make this question more useful and generic for others. I know I could use a CMS instead of starting from scratch, but sometimes I don't need an entire CMS to do minor things... What steps should I follow to create a website? Let's suppose I have a web designer. First of all, the designer designs the entire website (CSS, etc) and then I do the programming stuffs, like loading dynamically things from databases, doing some client-side stuffs with javascript, etc? Or how is the best way to do it? Edit: I'm not looking for tools/frameworks/languages suggestions. What I want to know is how a team (or a developer with a designer) starts creating a website. The steps they do, what tasks they do first, how they integrate the work, etc. An example of an answer could be: 1) Design the entire website with good CSS practices, using containers instead of tables in some cases, etc. 2) Use that design and develop the logic or the functionalities of the website. Of course, that's just an example. I'm looking for a good way to approach it, because I've been wanting to start on it but don't really know how exactly to organize the job :/

  • Is dynamic HTML layout good from an SEO perspective?

    - by sll
    Just wondering whether dynamically built HTML layout is fine from SEO perspectives? So let's assume e-commerce engine and its most popular page - products catalog. So 90% of the page is built using AJAX and MVVM library knockoutjs which builds HTML on the fly on the client side. So how search bots would parse such content? Is it fine indexed and would be such effective as server-side built HTML pages from the SEO perspectives?

  • Maintaining packages with code - Adding a property expression programmatically

    Every now and then I've come across scenarios where I need to update a lot of packages all in the same way. The usual scenario revolves around a group of packages all having been built off the same package template, and something needs to updated to keep up with new requirements, a new logging standard for example.You'd probably start by updating your template package, but then you need to address all your existing packages. Often this can run into the hundreds of packages and clearly that's not a job anyone wants to do by hand. I normally solve the problem by writing a simple console application that looks for files and patches any package it finds, and it is an example of this I'd thought I'd tidy up a bit and publish here. This sample will look at the package and find any top level Execute SQL Tasks, and change the SQL Statement property to use an expression. It is very simplistic working on top level tasks only, so nothing inside a Sequence Container or Loop will be checked but obviously the code could be extended for this if required. The code that actually sets the expression is shown below, the rest is just wrapper code to find the package and to find the task. /// <summary> /// The CreationName of the Tasks to target, e.g. Execute SQL Task /// </summary> private const string TargetTaskCreationName = "Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask.ExecuteSQLTask, Microsoft.SqlServer.SQLTask, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"; /// <summary> /// The name of the task property to target. /// </summary> private const string TargetPropertyName = "SqlStatementSource"; /// <summary> /// The property expression to set. /// </summary> private const string ExpressionToSet = "@[User::SQLQueryVariable]"; .... // Check if the task matches our target task type if (taskHost.CreationName == TargetTaskCreationName) { // Check for the target property if (taskHost.Properties.Contains(TargetPropertyName)) { // Get the property, check for an expression and set expression if not found DtsProperty property = taskHost.Properties[TargetPropertyName]; if (string.IsNullOrEmpty(property.GetExpression(taskHost))) { property.SetExpression(taskHost, ExpressionToSet); changeCount++; } } } This is a console application, so to specify which packages you want to target you have three options: Find all packages in the current folder, the default behaviour if no arguments are specified TaskExpressionPatcher.exe .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; } Find all packages in a specified folder, pass the folder as the argument TaskExpressionPatcher.exe C:\Projects\Alpha\Packages\ .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; } Find a specific package, pass the file path as the argument TaskExpressionPatcher.exe C:\Projects\Alpha\Packages\Package.dtsx The code was written against SQL Server 2005, but just change the reference to Microsoft.SQLServer.ManagedDTS to be the SQL Server 2008 version and it will work fine. If you get an error Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: The package failed to load due to error 0xC0011008… then check that the package is from the correct version of SSIS compared to the referenced assemblies, 2005 vs 2008 in other words.

  • Does UX matter for enterprise software?

    - by Ryan
    I've come to notice that a lot of software that companies use for managing things like time, expenses, setting up phone systems, etc is very non-intuitive from a user experience point of view. I know personally I waste a lot of time just trying to figure out how to navigate these systems, especially if I don't have a co-worker close by who I can bug to help me out. The help files are usually just as bad as the user interface itself. Are companies that complacent or are there just not any comparable enterprise products out there which do the job for these sorts of tasks? It seems that on the consumer side there is plenty of market opportunity for creating better user experiences, but how about for enterprise software? Obviously a certain level of slickness is not going to matter to a company, but when a better UX design translates to time saved, it's hard to argue against that. Edit: I'm not referring to in-house applications, but rather off the shelf systems from large software companies.

  • What is the most accurate/frequent report on browser usage on the Internet?

    - by Ryan Hayes
    I'm determining which browsers a new site should support. I'm looking for a respected and accurate (as possible) report on the browser versions that are currently in use. This report should, at minimum cover the % of people who use what browsers, and versions of that browser. Is there a widely accepted source for this kind of report? If so, are they regularly released and available for free? Bonus points for other metrics such as breaking down by OS, Flash versions, JS versions, etc.

  • What Web Technology to use?

    - by Sven
    Hey guys, I would like to start a project and I am concerning what kind of programming language/web framework to use. There is not that much logic involved. It's about a community-page with a lot of users(not that much at the beginning but I would like to be ready to welcome a lot), that should be able to communicate through private messages and a forum and there will be a lot of content (news, articles) to consume. I also want to provide several authorization settings to provide some content for only specific people. In fact it's about a content management system, but I want to design it functionally myself. And I want to use some external APIs. The only website I can think of with almost similar functionality is pokerstrategy.com. I looked up their job offers and it seems like they use java and php Maybe you guys can give me your thoughts. What would you use to encounter that requirements and how would you apprach? Thank you

  • What are requirements for a successful SOA?

    - by Amir Rezaei
    I’m an EA in an organisation with 10000+ employees. Strategically we are heading towards SOA. Currently I’m researching about SOA’s and creating a road map and I have come over many blogs that talk about “SOA is dead”. We can all agree that SOA is not just web-services. The problem is that I have hard to find any information on the reason behind SOA-fail stories in enterprises. What went bad and what went right? My question is: What are common SOA mistakes in enterprises that make SOA fail in long term? Is the any best practice for SOA? What are the most important requirements for a successful SOA in an enterprise? It would be good feedback towards our SOA strategy in this organisation. I have tried to narrow down the question, but it’s hard due to the nature of the question.

    - by Jesse Bunch
    So I'm really wanting to improve how I architect the software I code. I want to focus on maintainability and clean code. As you might guess, I've been reading a lot of resources on this topic and all it's doing is making it harder for me to settle on an architecture because I can never tell if my design is the one that the more experienced programmer would've chosen. So I have these requirements: I should connect to one vendor and download form submissions from their API. We'll call them the CompanyA. I should then map those submissions to a schema fit for submitting to another vendor for integration with the email service provider. We'll call them the CompanyB. I should then submit those responses to the ESP (CompanyB) and then instruct the ESP to send that submitter an email. So basically, I'm copying data from one web service to another and then performing an action at the latter web service. I've identified a couple high-level services: The service that downloads data from CompanyA. I called this the CompanyAIntegrator. The service that submits the data to CompanyB. I called this CompanyBIntegrator. So my questions are these: Is this a good design? I've tried to separate the concerns and am planning to use the facade pattern to make the integrators interchangeable if the vendors change in the future. Are my naming conventions accurate and meaningful to you (who knows nothing specific of the project)? Now that I have these services, where should I do the work of taking output from the CompanyAIntegrator and getting it in the format for input to the CompanyBIntegrator? Is this OK to be done in main()? Do you have any general pointers on how you'd code something like this? I imagine this scenario is common to us engineers---especially those working in agencies. Thanks for any help you can give. Learning how to architect well is really mind-cluttering.

  • When is your interview?

    - by Rob Farley
    Sometimes it’s tough to evaluate someone – to figure out if you think they’d be worth hiring. These days, since starting LobsterPot Solutions, I have my share of interviews, on both sides of the desk. Sometimes I’m checking out potential staff members; sometimes I’m persuading someone else to get us on board for a project. Regardless of who is on which side of the desk, we’re both checking each other out. The world is not how it was some years ago. I’m pretty sure that every time I walk into a room for an interview, I’ve searched for them online, and they’ve searched for me. I suspect they usually have the easier time finding me, although there are obviously other Rob Farleys in the world. They may have even checked out some of my presentations from conferences, read my blog posts, maybe even heard me tell jokes or sing. I know some people need me to explain who I am, but for the most part, I think they’ve done plenty of research long before I’ve walked in the room. I remember when this was different (as it could be for you still). I remember a time when I dealt with recruitment agents, looking for work. I remember sitting in rooms having been giving a test designed to find out if I knew my stuff or not, and then being pulled into interviews with managers who had to find out if I could communicate effectively. I’d need to explain who I was, what kind of person I was, what my value-system involved, and so on. I’m sure you understand what I’m getting at. (Oh, and in case you hadn’t realised, it’s a T-SQL Tuesday post, this month about interviews.) At TechEd Australia some years ago (either 2009 or 2010 – I forget which), I remember hearing a comment made during the ‘locknote’, the closing session. The presenter described a conversation he’d heard between two girls, discussing a guy that one of them had just started dating. The other girl expressed horror at the fact that her friend had met this guy in person, rather than through an online dating agency. The presenter pointed out that people realise that there’s a certain level of safety provided through the checks that those sites do. I’m not sure I completely trust this, but I’m sure it’s true for people’s technical profiles. If I interview someone, I hope they have a profile. I hope I can look at what they already know. I hope I can get samples of their work, and see how they communicate. I hope I can get a feel for their sense of humour. I hope I already know exactly what kind of person they are – their value system, their beliefs, their passions. Even their grammar. I can work out if the person is a good risk or not from who they are online. If they don’t have an online presence, then I don’t have this information, and the risk is higher. So if you’re interviewing with me, your interview started long before the conversation. I hope it started before I’d ever heard of you. I know the interview in which I’m being assessed started before I even knew there was a product called SQL Server. It’s reflected in what I write. It’s in the way I present. I have spent my life becoming me – so let’s talk! @rob_farley

  • Can AJAX in a CMS slow down your server

    - by Saif Bechan
    I am currently developing some plugins for WordPress, and I was wondering which route to take. Let's take an example, you want to display the last 3 tweets on your page. Option 1 You do things the normal way inside WordPress. Someone enters the website, while generating the page, you fetch the tweets in php via the twitter api, and just display them where you want. Now the small problem with this is, that you have to wait for the response from twitter. This takes a few ms. NO real problem, but this is question is just out of curiosity. Option 2 Here you don't do anything in WordPress on the initial load, but you do have the API inside. Now you just generate the page, and as soon as the page is done on the client side, you do a small AJAX call back to the server via a WordPress plugin, to fetch your latest tweets. Also called asynchronously. Now the problem with this IMO is that you have much more stress on your server. For starters you have two HTTP requests instead of one. Secondly the WordPress core has to load two times instead of one. Other options Now I know there are a lot of other options: 1) Getting the tweets directly via javascript, no stress on the server at all. 2) Cache the tweets so they are fetched from the DB instead of using the API every time. 3) Getting the tweets from an ajax call that is not a WordPress plugin. 4) Many more. My Question Now my question is if you only compare 1 and 2, which would be a better choice.

  • Learning c++ by contributing to open source projects

    - by user1189880
    I have some general programming experience with a few different languages, my most skilled being php. I want to spend a lot of time over the next year learning c++ in much more depth and then eventually get to a good enough level to find a job as a junior developer working in c++. I really struggle to find things to develop as toy programs so want to contribute to an open source project in c++ to get really stuck in to. But the projects I see on github in c++ are very large and will require a lot of knowlege to even get started. Are there any smaller projects that I can contribute to or are there any other good ideas for learning c++ from a practical level.
