  • ROOT_MISMATCH error after following FAQ directions

    - by Adko
    While using Ubuntu One in 11.04 I am unable to change my account info. When I made the switch to 11.04 I forgot that I already had an Ubuntu One account so, I made a new one. However, upon going through one of my email accounts I found my old Ubuntu One login information. I then attempted to switch the account associated with my desktop to my first email. Now, despite following the directions found at https://wiki.ubuntu.com/UbuntuOne/FAQ/WhatToDoWhenSyncdaemonSaysRootMismatch I continue to get the error "File sync error. (local and server roots are different (ROOT_MISMATCH))". Any help would be appreciated.

  • Java FAQ: Tudo o que você precisa saber

    - by Bruno.Borges
    Com frequência recebo e-mails de clientes com dúvidas sobre "quando sairá a próxima versão do Java?", ou então "quando vai expirar o Java?" ou ainda "quais as mudanças da próxima versão?". Por isso resolvi escrever aqui um FAQ, respondendo estas dúvidas e muitas outras. Este post estará sempre atualizado, então se você possui alguma dúvida, envie para mim no Twitter @brunoborges. Qual a diferença entre o Oracle JDK e o OpenJDK?O projeto OpenJDK funciona como a implementação de referência Open Source do Java Standard Edition. Empresas como a Oracle, IBM, e Azul Systems suportam e investem no projeto OpenJDK para continuar evoluindo a plataforma Java. O Oracle JDK é baseado no OpenJDK, mas traz outras ferramentas como o Mission Control, e a máquina virtual traz algumas features avançadas como por exemplo o Flight Recorder. Até a versão 6, a Oracle oferecia duas máquinas virtuais: JRockit (BEA) e HotSpot (Sun). A partir da versão 7 a Oracle unificou as máquinas virtuais, e levou as features avançadas do JRockit para dentro da VM HotSpot. Leia também o OpenJDK FAQ. Onde posso obter binários beta Early Access do JDK 7, JDK 8, JDK 9 para testar?A partir do projeto OpenJDK, existe um projeto específico para cada versão do Java. Nestes projetos você pode encontrar binários beta Early Access, além do código-fonte. JDK 6 - http://jdk6.java.net/ JDK 7 - http://jdk7.java.net/ JDK 8 - http://jdk8.java.net/ JDK 9 - http://jdk9.java.net/ Quando acaba o suporte do Oracle Java SE 6, 7, 8? Somente produtos e versões com release oficial são suportados pela Oracle (exemplo: não há suporte para binários beta do JDK 7, JDK 8, ou JDK 9). Existem duas categorias de datas que o usuriário do Java deve estar ciente:  EOPU - End of Public UpdatesMomento em que a Oracle não mais disponibiliza publicamente atualizações Oracle SupportPolítica de suporte da Oracle para produtos, incluindo o Oracle Java SE O Oracle Java SE é um produto e portando os períodos de suporte são regidos pelo Oracle Lifetime Support Policy. Consulte este documento para datas atualizadas e específicas para cada versão do Java. O Oracle Java SE 6 já atingiu EOPU (End of Public Updates) e agora é mantido e atualizado somente para clientes através de contrato comercial de suporte. Para maiores informações, consulte a página sobre Oracle Java SE Support.  O mais importante aqui é você estar ciente sobre as datas de EOPU para as versões do Java SE da Oracle.Consulte a página do Oracle Java SE Support Roadmap e busque nesta página pela tabela com nome Java SE Public Updates. Nela você encontrará a data em que determinada versão do Java irá atingir EOPU. Como funciona o versionamento do Java?Em 2013, a Oracle divulgou um novo esquema de versionamento do Java para facilmente identificar quando é um release CPU e quando é um release LFR, e também para facilitar o planejamento e desenvolvimento de correções e features para futuras versões. CPU - Critical Patch UpdateAtualizações com correções de segurança. Versão será múltipla de 5, ou com soma de 1 para manter o número ímpar. Exemplos: 7u45, 7u51, 7u55. LFR - Limited Feature ReleaseAtualizações com correções de funcionalidade, melhorias de performance, e novos recursos. Versões de números pares múltiplos de 20, com final 0. Exemplos: 7u40, 7u60, 8u20. Qual a data da próxima atualização de segurança (CPU) do Java SE?Lançamentos do tipo CPU são controlados e pré-agendados pela Oracle e se aplicam a todos os produtos, inclusive o Oracle Java SE. Estes releases acontecem a cada 3 meses, sempre na Terça-feira mais próxima do dia 17 dos meses de Janeiro, Abril, Julho, e Outubro. Consulte a página Critical Patch Updates, Security Alerts and Third Party Bulleting para saber das próximas datas. Caso tenha interesse, você pode acompanhar através de recebimentos destes boletins diretamente no seu email. Veja como assinar o Boletim de Segurança da Oracle. Qual a data da próxima atualização de features (LFR) do Java SE?A Oracle reserva o direito de não divulgar estas datas, assim como o faz para todos os seus produtos. Entretanto é possível acompanhar o desenvolvimento da próxima versão pelos sites do projeto OpenJDK. A próxima versão do JDK 7 será o update 60 e binários beta Early Access já estão disponíveis para testes. A próxima versão doJDK 8 será o update 20 e binários beta Early Access já estão disponíveis para testes. Onde posso ver as mudanças e o que foi corrigido para a próxima versão do Java?A Oracle disponibiliza um changelog para cada binário beta Early Access divulgado no portal Java.net. JDK 7 update 60 changelogs JDK 8 update 20 changelogs Quando o Java da minha máquina (ou do meu usuário) vai expirar?Conheçendo o sistema de versionamento do Java e a periodicidade dos releases de CPU, o usuário pode determinar quando que um update do Java irá expirar. De todo modo, a cada novo update, a Oracle já informa quando que este update deverá expirar diretamente no release notes da versão. Por exemplo, no release notes da versão Oracle Java SE 7 update 55, está escrito na seção JRE Expiration Date o seguinte: The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 7u55) will expire with the release of the next critical patch update scheduled for July 15, 2014. For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 7u55) on August 15, 2014. After either condition is met (new release becoming available or expiration date reached), the JRE will provide additional warnings and reminders to users to update to the newer version. For more information, see JRE Expiration Date.Ou seja, a versão 7u55 irá expirar com o lançamento do próximo release CPU, pré-agendado para o dia 15 de Julho de 2014. E caso o computador do usuário não possa se comunicar com o servidor da Oracle, esta versão irá expirar forçadamente no dia 15 de Agosto de 2014 (através de um mecanismo embutido na versão 7u55). O usuário não é obrigado a atualizar para versões LFR e portanto, mesmo com o release da versão 7u60, a versão atual 7u55 não irá expirar.Veja o release notes do Oracle Java SE 8 update 5. Encontrei um bug. Como posso reportar bugs ou problemas no Java SE, para a Oracle?Sempre que possível, faça testes com os binários beta antes da versão final ser lançada. Qualquer problema que você encontrar com estes binários beta, por favor descreva o problema através do fórum de Project Feebdack do JDK.Caso você encontre algum problema em uma versão final do Java, utilize o formulário de Bug Report. Importante: bugs reportados por estes sistemas não são considerados Suporte e portanto não há SLA de atendimento. A Oracle reserva o direito de manter o bug público ou privado, e também de informar ou não o usuário sobre o progresso da resolução do problema. Tenho uma dúvida que não foi respondida aqui. Como faço?Se você possui uma pergunta que não foi respondida aqui, envie para bruno.borges_at_oracle.com e caso ela seja pertinente, tentarei responder neste artigo. Para outras dúvidas, entre em contato pelo meu Twitter @brunoborges.

  • Faq and Best tips Regarding Learning Database ?

    - by AdityaGameProgrammer
    For a programmer with no prior exposure to databases What would be a good database to learn Oracle vs SQLserver vs MySQLvs PostgreSQL? I have come across lot of discussion MySQL and PostgreSQL and frankly I am confused on which to start with. Are these very different, in the sense if one had to switch, would the exposure to one be counter-productive to learning the other? Is working with databases heavily platform dependent? What exactly do people mean by Data base programming vs. administration? Do people chose databases based on the programming language used for the application developed? In general, Working with databases is it implicit that we work with some server? Does the choice of databases differ when it comes to game development? If so what factors does it differ by? What are the Best Tips that you have found to be useful when learning databases Edit: Some FAQ i had and found the same on SO What should every developer know about databases? Which database if learning from scratch in 2010? For a beginner, is there much difference between MySQL and PostgreSQL What RDBMS should I learn/use? (MySql/SQL Server/Oracle etc.) To what extent should a developer learn database? How are database programmers different from other programmers? what kind of database are used in games?

  • FAQ: GridView Calculation with JavaScript

    - by Vincent Maverick Durano
    In my previous post I wrote a simple demo on how to Calculate Totals in GridView and Display it in the Footer. Basically what it does is it calculates the total amount by typing into the TextBox and display the grand total in the footer of the GridView and basically it was a server side implemenation.  Many users in the forums are asking how to do the same thing without postbacks and how to calculate both amount and total amount together. In this post I will demonstrate how to do this using JavaScript. To get started let's go ahead and set up the form. Just for the simplicity of this demo I just set up the form like this:   <asp:gridview ID="GridView1" runat="server" ShowFooter="true" AutoGenerateColumns="false"> <Columns> <asp:BoundField DataField="RowNumber" HeaderText="Row Number" /> <asp:BoundField DataField="Description" HeaderText="Item Description" /> <asp:TemplateField HeaderText="Item Price"> <ItemTemplate> <asp:Label ID="LBLPrice" runat="server" Text='<%# Eval("Price") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Quantity"> <ItemTemplate> <asp:TextBox ID="TXTQty" runat="server"></asp:TextBox> </ItemTemplate> <FooterTemplate> <b>Total Amount:</b> </FooterTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Sub-Total"> <ItemTemplate> <asp:Label ID="LBLSubTotal" runat="server"></asp:Label> </ItemTemplate> <FooterTemplate> <asp:Label ID="LBLTotal" runat="server" ForeColor="Green"></asp:Label> </FooterTemplate> </asp:TemplateField> </Columns> </asp:gridview>   As you can see there's no fancy about the mark up above. It just a standard GridView with BoundFields and TemplateFields on it. Now just for the purpose of this demo I just use a dummy data for populating the GridView. Here's the code below:   public partial class GridCalculation : System.Web.UI.Page { private void BindDummyDataToGrid() { DataTable dt = new DataTable(); DataRow dr = null; dt.Columns.Add(new DataColumn("RowNumber", typeof(string))); dt.Columns.Add(new DataColumn("Description", typeof(string))); dt.Columns.Add(new DataColumn("Price", typeof(string))); dr = dt.NewRow(); dr["RowNumber"] = 1; dr["Description"] = "Nike"; dr["Price"] = "1000"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["RowNumber"] = 2; dr["Description"] = "Converse"; dr["Price"] = "800"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["RowNumber"] = 3; dr["Description"] = "Adidas"; dr["Price"] = "500"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["RowNumber"] = 4; dr["Description"] = "Reebok"; dr["Price"] = "750"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["RowNumber"] = 5; dr["Description"] = "Vans"; dr["Price"] = "1100"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["RowNumber"] = 6; dr["Description"] = "Fila"; dr["Price"] = "200"; dt.Rows.Add(dr); //Bind the Gridview GridView1.DataSource = dt; GridView1.DataBind(); } protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { BindDummyDataToGrid(); } } }   Now try to run the page. The output should look something like below: The Client-Side Calculation Here's the code for the GridView calculation:   <script type="text/javascript"> function CalculateTotals() { var gv = document.getElementById("<%= GridView1.ClientID %>"); var tb = gv.getElementsByTagName("input"); var lb = gv.getElementsByTagName("span"); var sub = 0; var total = 0; var indexQ = 1; var indexP = 0; for (var i = 0; i < tb.length; i++) { if (tb[i].type == "text") { sub = parseFloat(lb[indexP].innerHTML) * parseFloat(tb[i].value); if (isNaN(sub)) { lb[i + indexQ].innerHTML = ""; sub = 0; } else { lb[i + indexQ].innerHTML = sub; } indexQ++; indexP = indexP + 2; total += parseFloat(sub); } } lb[lb.length -1].innerHTML = total; } </script>   The code above calculates the sub-total by multiplying the price and the quantity and at the same time calculates the total amount  by adding the sub-total values. Now you can simply call the JavaScript function above like this:   <ItemTemplate> <asp:TextBox ID="TXTQty" runat="server" onkeyup="CalculateTotals();"></asp:TextBox> </ItemTemplate>   Running the code above will display something like below: That's it! I hope someone find this post useful! Technorati Tags: ASP.NET,JavaScript,GridView,TipsTricks

  • FAQ: GridView Calculation with JavaScript - Formatting and Validation

    - by Vincent Maverick Durano
    In my previous post here we've talked about how to calculate the sub-totals and grand total in GridView using JavaScript. In this post I'm going take more step further and will demonstrate how are we going to format the totals into a currency and how to validate the input that would only allow you to enter a whole number in the quantity TextBox.

  • FAQ: Reshipping a Sun Certification

    - by Paul Sorensen
    If you obtained a Sun Certification before September 1, 2010, your success kit was shipped to the mailing address on record in your profile at certmanager.net/sun. At this time, if you require a reshipment for any reason of your original Sun Certification Certificate (it got damaged in the mail, you did not receive it, it needs to be sent to a different address, etc...), you will now receive access to an electronic reproduction of your original Certificate called an eCertificate. The Sun Certification ID card is no longer available and cannot be ordered from Oracle. This is to allow us to streamline this reshipping process and allow candidates to receive these certificates as quickly as possible.Candidates who earned a Java, Oracle Solaris, MySQL, NetBeans or OpenOffice.org certification on or after September 1, 2010 will receive their success kits in the mail within 6-8 weeks of completing the final certification requirement.

  • FAQ: GridView Calculation with JavaScript - Displaying Quantity Total

    - by Vincent Maverick Durano
    Previously we've talked about how calculate the sub-totals and grand total in GridView here, how to format the numbers into a currency format and how to validate the quantity to just accept whole numbers using JavaScript here. One of the users in the forum (http://forums.asp.net) is asking if how to modify the script to display the quantity total in the footer. In this post I'm going to show you how to it. Basically we just need to modify the javascript CalculateTotals function and add the codes there for calculating the quantity total and display it in the footer.

  • FAQ: Highlight GridView Row on Click and Retain Selected Row on Postback

    - by Vincent Maverick Durano
    A couple of months ago I’ve written a simple demo about “Highlighting GridView Row on MouseOver”. I’ve noticed many members in the forums (http://forums.asp.net) are asking how to highlight row in GridView and retain the selected row across postbacks. So I’ve decided to write this post to demonstrate how to implement it as reference to others who might need it. In this demo I going to use a combination of plain JavaScript and jQuery to do the client-side manipulation. I presumed that you already know how to bind the grid with data because I will not include the codes for populating the GridView here. For binding the gridview you can refer this post: Binding GridView with Data the ADO.Net way or this one: GridView Custom Paging with LINQ. To get started let’s implement the highlighting of GridView row on row click and retain the selected row on postback.  For simplicity I set up the page like this: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>You have selected Row: (<asp:Label ID="Label1" runat="server" />)</h2> <asp:HiddenField ID="hfCurrentRowIndex" runat="server"></asp:HiddenField> <asp:HiddenField ID="hfParentContainer" runat="server"></asp:HiddenField> <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Trigger Postback" /> <asp:GridView ID="grdCustomer" runat="server" AutoGenerateColumns="false" onrowdatabound="grdCustomer_RowDataBound"> <Columns> <asp:BoundField DataField="Company" HeaderText="Company" /> <asp:BoundField DataField="Name" HeaderText="Name" /> <asp:BoundField DataField="Title" HeaderText="Title" /> <asp:BoundField DataField="Address" HeaderText="Address" /> </Columns> </asp:GridView> </asp:Content>   Note: Since the action is done at the client-side, when we do a postback like (clicking on a button) the page will be re-created and you will lose the highlighted row. This is normal because the the server doesn't know anything about the client/browser not unless if you do something to notify the server that something has changed. To persist the settings we will use some HiddenFields control to store the data so that when it postback we can reference the value from there. Now here’s the JavaScript functions below: <asp:content id="Content1" runat="server" contentplaceholderid="HeadContent"> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript"></script> <script type="text/javascript">       var prevRowIndex;       function ChangeRowColor(row, rowIndex) {           var parent = document.getElementById(row);           var currentRowIndex = parseInt(rowIndex) + 1;                 if (prevRowIndex == currentRowIndex) {               return;           }           else if (prevRowIndex != null) {               parent.rows[prevRowIndex].style.backgroundColor = "#FFFFFF";           }                 parent.rows[currentRowIndex].style.backgroundColor = "#FFFFD6";                 prevRowIndex = currentRowIndex;                 $('#<%= Label1.ClientID %>').text(currentRowIndex);                 $('#<%= hfParentContainer.ClientID %>').val(row);           $('#<%= hfCurrentRowIndex.ClientID %>').val(rowIndex);       }             $(function () {           RetainSelectedRow();       });             function RetainSelectedRow() {           var parent = $('#<%= hfParentContainer.ClientID %>').val();           var currentIndex = $('#<%= hfCurrentRowIndex.ClientID %>').val();           if (parent != null) {               ChangeRowColor(parent, currentIndex);           }       }          </script> </asp:content>   The ChangeRowColor() is the function that sets the background color of the selected row. It is also where we set the previous row and rowIndex values in HiddenFields.  The $(function(){}); is a short-hand for the jQuery document.ready event. This event will be fired once the page is posted back to the server that’s why we call the function RetainSelectedRow(). The RetainSelectedRow() function is where we referenced the current selected values stored from the HiddenFields and pass these values to the ChangeRowColor() function to retain the highlighted row. Finally, here’s the code behind part: protected void grdCustomer_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes.Add("onclick", string.Format("ChangeRowColor('{0}','{1}');", e.Row.ClientID, e.Row.RowIndex)); } } The code above is responsible for attaching the javascript onclick event for each row and call the ChangeRowColor() function and passing the e.Row.ClientID and e.Row.RowIndex to the function. Here’s the sample output below:   That’s it! I hope someone find this post useful! Technorati Tags: jQuery,GridView,JavaScript,TipTricks

  • FAQ&ndash;Highlight GridView Row on Click and Retain Selected Row on Postback

    - by Vincent Maverick Durano
    A couple of months ago I’ve written a simple demo about “Highlighting GridView Row on MouseOver”. I’ve noticed many members in the forums (http://forums.asp.net) are asking how to highlight row in GridView and retain the selected row across postbacks. So I’ve decided to write this post to demonstrate how to implement it as reference to others who might need it. In this demo I going to use a combination of plain JavaScript and jQuery to do the client-side manipulation. I presumed that you already know how to bind the grid with data because I will not include the codes for populating the GridView here. For binding the gridview you can refer this post: Binding GridView with Data the ADO.Net way or this one: GridView Custom Paging with LINQ. To get started let’s implement the highlighting of GridView row on row click and retain the selected row on postback.  For simplicity I set up the page like this: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>You have selected Row: (<asp:Label ID="Label1" runat="server" />)</h2> <asp:HiddenField ID="hfCurrentRowIndex" runat="server"></asp:HiddenField> <asp:HiddenField ID="hfParentContainer" runat="server"></asp:HiddenField> <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Trigger Postback" /> <asp:GridView ID="grdCustomer" runat="server" AutoGenerateColumns="false" onrowdatabound="grdCustomer_RowDataBound"> <Columns> <asp:BoundField DataField="Company" HeaderText="Company" /> <asp:BoundField DataField="Name" HeaderText="Name" /> <asp:BoundField DataField="Title" HeaderText="Title" /> <asp:BoundField DataField="Address" HeaderText="Address" /> </Columns> </asp:GridView> </asp:Content>   Note: Since the action is done at the client-side, when we do a postback like (clicking on a button) the page will be re-created and you will lose the highlighted row. This is normal because the the server doesn't know anything about the client/browser not unless if you do something to notify the server that something has changed. To persist the settings we will use some HiddenFields control to store the data so that when it postback we can reference the value from there. Now here’s the JavaScript functions below: <asp:content id="Content1" runat="server" contentplaceholderid="HeadContent"> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript"></script> <script type="text/javascript">       var prevRowIndex;       function ChangeRowColor(row, rowIndex) {           var parent = document.getElementById(row);           var currentRowIndex = parseInt(rowIndex) + 1;                 if (prevRowIndex == currentRowIndex) {               return;           }           else if (prevRowIndex != null) {               parent.rows[prevRowIndex].style.backgroundColor = "#FFFFFF";           }                 parent.rows[currentRowIndex].style.backgroundColor = "#FFFFD6";                 prevRowIndex = currentRowIndex;                 $('#<%= Label1.ClientID %>').text(currentRowIndex);                 $('#<%= hfParentContainer.ClientID %>').val(row);           $('#<%= hfCurrentRowIndex.ClientID %>').val(rowIndex);       }             $(function () {           RetainSelectedRow();       });             function RetainSelectedRow() {           var parent = $('#<%= hfParentContainer.ClientID %>').val();           var currentIndex = $('#<%= hfCurrentRowIndex.ClientID %>').val();           if (parent != null) {               ChangeRowColor(parent, currentIndex);           }       }          </script> </asp:content>   The ChangeRowColor() is the function that sets the background color of the selected row. It is also where we set the previous row and rowIndex values in HiddenFields.  The $(function(){}); is a short-hand for the jQuery document.ready function. This function will be fired once the page is posted back to the server that’s why we call the function RetainSelectedRow(). The RetainSelectedRow() function is where we referenced the current selected values stored from the HiddenFields and pass these values to the ChangeRowColor) function to retain the highlighted row. Finally, here’s the code behind part: protected void grdCustomer_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes.Add("onclick", string.Format("ChangeRowColor('{0}','{1}');", e.Row.ClientID, e.Row.RowIndex)); } } The code above is responsible for attaching the javascript onclick event for each row and call the ChangeRowColor() function and passing the e.Row.ClientID and e.Row.RowIndex to the function.

  • Improving FAQ SEO with multiple pages?

    - by asdfasdf
    I have a client who has over 200 Question/Answer style content blocks. Neither the questions or answers are very long and most of them have almost the same question but with a word or two differentiating themselves from the rest of the questions. Would SEO be helped or hurt if I would to put each QA on its own page with the title of the page the question being asked etc... Or, would that be considered "farming"? If not, what would be the best way (in SEO world) do present all these QAs? Thanks for any advice..
