  • One site being on a subdirectory of another. Does google count this against you?

    - by Mick
    I have created two similar websites (relating to monetary systems). So far, one appears to be loved by Google and the other hated. I'm struggling to work out why. This is a mystery to me because both sites were created by me with the same design philosophy, both in pure html. Both are packed to the rafters with references to, and information about, their respective subjects. One issue I'm worried may be the cause is to do with the location of the sites. I got a web hosting package from hostmonster.com for the successful one, but less liked one is just an "add-on" which sits on a subdirectory of the successful one. I wonder if Google somehow detects this and treats it as a less significant website? EDIT: Just to clarify, even though one site is an add-on that sits on a subdirectory of the other, the URL is arranged to look like it is a root. I.e. the unpopular site can be accessed directly with a simple www.myunpopularsite.com name, without specifying any subdirectory. EDIT: Just in case its important... say the popular site is called pop.com and the unpopular one unpop.com. In the webspace I've purchased, there is a directory called public_html. This is where I put the index.htm and all the other files of my popular site. When I purchased the add-on unpop.com. I made a subdirectory of public_html called unpop. It is within this "public_html\unpop\" that I place the index.htm and all the other files of my unpopular site. Typing www.unpop.com into the address bar of a browser links directly to the contents of "public_html\unpop\" and the user is not aware that this site is sitting on a subdirectory of another site. BUT if you type "www.pop.com/unpop" into the address bar of a browser you DO see the unpopular site.

  • Hosting several HTTP servers on single domain name

    - by Nakilon
    Several people have got a single domain name server.company.com server, where they are now supposed to host their infrastructure or temporal projects, written in different ways even in different programming languages. How do they divide the domain? Split into subdomains: john.server.company.com, kate.server.company.com, etc. This would need a lot of admins' assistance, time, etc. -- there would be no way for John and Kate to do it themselves. Split into url namespaces: server.company.com/john/, server.company.com/kate/, etc. Pro: They now can make a single welcome page at root with any additional info (if they need?) Con: Each server would need to know their namespace string constant, and hrefs like / whould need patching. Split into ports: server.company.com:8080, server.company.com:8081, etc. and make a single :80 welcome page. Pro: They still can make a single welcome page at :80 Con: ??? I would like to know more pros and cons for 2 and 3 solution.

    I'm trying to send an email through Google from my localhost. (via PHP5.3) But Google keeps on blocking my requests.

  • SEO & Multilingual: would be this a good practise?

    - by Younès
    I am currently making a bilingual website and I'd like to get nice SEO results of course. Here's my idea: The internal links would be composed of the "www" subdomain so that people can share links regardless of their language. Anyway, their language is determined by the HTTP_ACCEPT_LANGUAGE PHP variable. So, they would see http:// www.site.com/mydocument/123 in their adress bar and never see any links like "http:// fr.site.com/mydocument/123" or "http://en.site.com/mydocument/123" The user can always switch the page's language thanks to links in the footer. The switching language link would be : http:// fr.site.com/mydocument/123 , and clicking on it would change his language session and redirects the user to http:// www.site.com/mydocument/123 In case of a crawling bot: I read that if the HTTP_USER_LANGUAGE variable was missing then it's a crawling bot. So, in that case, we set the defaut language as English. Each page, as I mentionned earlier, has a link for another language: On the page: http:// www.site.com/document/1323, the link http:// fr.site.com/document/1323 can be seen by the bot and be crawled. What do you think about this practise ? Would I get good SEO results for each language ?

  • libGDX using Stage and Actor produces different camera angles on desktop and Android Phone

    - by Brandon
    libGDX using Stage and Actor produces different camera angles on desktop and Android Phone. Here are pictures demonstrating the problem: http://brandonyuh.minus.com/mFpdTSgN17VUq On the desktop version, the image takes up most all the screen. On the Android phone it only takes up a bit of the screen.

  • sIFR displays only the first line of text in Opera when on transparent background

    - by Gary
    I have implemented sIFR for the first time, on a test page. The code I have is below. It works fine in IE7, Firefox, Safari and Chrome, but in Opera only the first line of sIFR-ed text appears when the page first loads and after refreshing the page. But, if I scroll the page, all the text appears! It seems to have to do with transparency, because if I turn transparency off, it works fine. Please can someone help me to make this work? Thanks, Gary <link rel="stylesheet" href="sIFR-print.css" type="text/css" media="print" /> <link rel="stylesheet" href="all.css" type="text/css" media="all" /> <script src="sifr.js" type="text/javascript"></script> <script src="sifr-config.js" type="text/javascript"></script> <script type="text/javascript"> //<![CDATA[ var sIFRfont = { src: 'fontname.swf' }; sIFR.activate(sIFRfont); sIFR.replace(sIFRfont, { css: [ '.sIFR-root { line-height: 1em; font-size: 64px; color: #000000; background-color: blue; text-align: left; font-weight: normal; font-style: normal; text-decoration: none; visibility: hidden; }' ], fitExactly : true, forceClear : true, forceSingleLine : false, selector : 'div.flashtext', transparent : true }); //]]> </script>

  • Using for or while loops

    - by Gary
    Every month, 4 or 5 text files are created. The data in the files is pulled into MS Access and used in a mailmerge. Each file contains a header. This is an example: HEADER|0000000130|0000527350|0000171250|0000058000|0000756600|0000814753|0000819455|100106 The 2nd field is the number of records contained in the file (excluding the header line). The last field is the date in the form yymmdd. Using gawk (for Windows), I've done ok with rearranging/modifying the data and writing it all out to a new file for importing into Access except for the following. I'm trying to create a unique ID number for each record. The ID number has the form 1mmddyyXXXX, where XXXX is a number, padded with leading zeros. Using the header above, the first record in the output file would get the ID number 10106100001 and the last record would get the ID 10106100130. I've tried putting the second field in the header into a variable, rearranging the last header field into the required date format and then looping with "for" statements to append the XXXX part of the ID and then outputting it all with printf but so far I've been complete rubbish at it. Thanks for your help! gary

  • Default vs Impl when implementing interfaces in Java

    - by Gary Rowe
    After reading Should package names be singular or plural? it occurred to me that I've never seen a proper debate covering one of my pet peeves: naming implementations of interfaces. Let's assume that you have a interface Order that is intended to be implemented in a variety of ways but there is only the initial implementation when the project is first created. Do you go for DefaultOrder or OrderImpl or some other variant to avoid the false dichotomy? And what do you do when more implementations come along? And most important... why?

  • &ldquo;My life at Oracle&rdquo;

    - by cristian.condurache(at)oracle.com
    Hello everybody! My name is Eva and I currently work in Oracle Italy as Sales Programs Manager for the Technology Sales organization. Since 2009, I also proudly represent the Oracle Education Foundation within my country as the Ambassador for Italy. My career path in this amazing company began 5 years ago as a fresh graduate: after various years studying abroad, in Germany and Ireland mainly, I was looking for a valuable and concrete opportunity which could fulfill my energetic spirit. I wanted to develop myself inside a stimulating and “fast” business environment.. and here came Oracle and I really couldn’t ask for anything better!  THE PARTNER EXPERIENCE The first department I had the chance to work into was the Alliances and Channels organization, where I had the opportunity to join a brilliant team of great and visionary guys. I began having the responsibility to analyze and rationalize the portfolio of Oracle business partners and to identify potential cross-area solutions, which had to be highlighted both on the local market and internationally: this ended up with the implementation of the “Partner Community” model, a business environment of selected Oracle partners, specialized on the different technology focus areas. This new concept was then recognized as an EMEA Best Practice and replicated internationally. Having the opportunity to strengthen day after day strategic relationships with several business partners and study the market positioning of their technology solutions, I was given the role to develop the “Oracle Partner Network Innovation Award” in Italy: the EMEA competition encouraging and rewarding proven and successful technology innovations, creating high value for our common customers and generating new business potential. Several Italian partner solutions won different prizes and I decided that it was worth collecting all those valuable projects, winners and short-listed, inside two specific books in order also to provide them an international market visibility: OPN Innovation Award Booklet 2007 and OPN Innovation Award Booklet 2008 Inside the Alliances and Channels department I really had the opportunity to do    amazing things, like for example working side-by-side with one of the most exceptional teams in Oracle I have ever worked with: the EMEA Recruitment Team. Together, in fact, we conceived a brand new business initiative for our partners, called “Oracle Campus Joint Program”. This program was awarded as an EMEA Best Practice and acknowledged by both Italian public institutions and press media. Italy   is currently running its 5th edition.   Briefly, the “Oracle Campus Joint Program” aims at facing the growing issue of lack of  technology competences and skills on the market. By identifying a specific technology area and developing an intensive 4-6 week Oracle University training course and by collaborating with important academic institutes, international “gurus” and professionals, our business partners are able to benefit from a pool of brilliant top talented young consultants and offer them a significant career opportunity. BUSINESS BUT NOT ONLY: THE NO-PROFIT EXPERIENCE OF ORACLE Currently my mission in Oracle is to continue driving the implementation of strategic business development and sales programs for the entire Oracle Technology stack, involving both partners and the end-customers. But as a completely distinguished role from the day-today business, I’m also honored to represent in Italy the charity global organization founded by Oracle - the Oracle Education Foundation - and drive its corporate citizenship and marketing programs. Oracle Education Foundation is an independent charitable organization funded by Oracle and is dedicated to helping students develop 21st century skills through project learning and the use of technology. It provides “ThinkQuest” as a free program to primary and secondary (K12) schools. Just some significant numbers: today 548,000 students/teachers in 47 countries use ThinkQuest and the Oracle Education Foundation partners with 40+ no-profit or government organizations globally. ABOUT MYSELF AND MY INTERESTS About myself…I’m very enthusiastic and positive, trying always to transform difficult issues in challenging opportunities. My day usually begins very early in the morning with running, swimming or when I need to collect some “zen” energies with a yoga session or better with a long walk with my dog. I definitely love animals and generally speaking I’m very keen on environmental issues and try, as much as I can, to carry out a healthy and “planet respectful” lifestyle. My thirst for knowledge pushed me some time ago to begin a new personal challenge: I decided to enroll, dedicating a good part of my free time, for a second university degree: I chose “Neuroeconomics”, an innovative academic path which combines psychology, economics, and neuroscience and studies how people make decisions and the role of the brain when people evaluate these decisions, categorizing risks and rewards and generally interacting with each other. I’ve been very glad to talk about my experience in this article, as working for Oracle is something very stimulating. This company ensures you the opportunity to face new challenges, work with highly talented people and be professionally highlighted also globally. Motivation, good results and innovation is always pursued, recognized and fully supported. Thanks and wish you all an amazing career! If you have any question please contact annapia.racanelli@oracle.com.

  • Oracle: Addressing Information Overload in Factory Automation

    - by [email protected]
     ORACLE's Stephen Slade has written about addressing information overload on the factory floor.  According to Slade, today's automated processes create large amounts of valuable data, but only a small percentage remains actionable.Oracle claims information overload can cost financially, as companies struggle to store and collect reams of data needed to identify embedded trends, while producing manual reports to meet quality standards, regulatory requirements and general reporting goals.Increasing scrutiny of new requirements and standards add to the need to find new ways to process data. Many companies are now using analytical engines to contextualise data into 'actionable information'. Oracle claims factories need to seriously address their data collection, audit trail and records retention processes. By organising their data, factories can maximise outcomes from excellence and contuinuous improvement programs, and gain visibility into costs int the supply chain.Analytics tools and technologies such as Business Intelligence (BI), Enterprise Manufacturing Intelligence (EMI) and Manufacturing Operations Centers (MOC) can help consolidate, contextual and distribute information.   FULL ARICLE:  http://www.myfen.com.au/news/oracle--addressing-information-overload-in-factory

  • Tutorial: Criando um Componente para o UCM

    - by Denisd
    Então você já instalou o UCM, seguindo o tutorial: http://blogs.oracle.com/ecmbrasil/2009/05/tutorial_de_instalao_do_ucm.html e também já fez o hands-on: http://blogs.oracle.com/ecmbrasil/2009/10/tutorial_de_ucm.html e agora quer ir além do básico? Quer começar a criar funcionalidades para o UCM? Quer se tornar um desenvolvedor do UCM? Quer criar o Content Server à sua imagem e semelhança?! Pois hoje é o seu dia de sorte! Neste tutorial, iremos aprender a criar um componente para o Content Server. O nosso primeiro componente, embora não seja tão simples, será feito apenas com recursos do Content Server. Em um futuro tutorial, iremos aprender a usar classes java como parte de nossos componentes. Neste tutorial, vamos desenvolver um recurso de Favoritos, aonde os usuários poderão marcar determinados documentos como seus Favoritos, e depois consultar estes documentos em uma lista. Não iremos montar o componente com todas as suas funcionalidades, mas com o que vocês verão aqui, será tranquilo aprimorar este componente, inclusive para ambientes de produção. Componente MyFavorites Algumas características do nosso componente favoritos: - Por motivos de espaço, iremos montar este componente de uma forma “rápida e crua”, ou seja, sem seguir necessariamente as melhores práticas de desenvolvimento de componentes. Para entender melhor a prática de desenvolvimento de componentes, recomendo a leitura do guia Working With Components. - Ele será desenvolvido apenas para português-Brasil. Outros idiomas podem ser adicionados posteriormente. - Ele irá apresentar uma opção “Adicionar aos Favoritos” no menu “Content Actions” (tela Content Information), para que o usuário possa definir este arquivo como um dos seus favoritos. - Ao clicar neste link, o usuário será direcionado à uma tela aonde ele poderá digitar um comentário sobre este favorito, para facilitar a leitura depois. - Os favoritos ficarão salvos em uma tabela de banco de dados que iremos criar como parte do componente - A aba “My Content Server” terá uma opção nova chamada “Meus Favoritos”, que irá trazer uma tela que lista os favoritos, permitindo que o usuário possa deletar os links - Alguns recursos ficarão de fora deste exercício, novamente por motivos de espaço. Mas iremos listar estes recursos ao final, como exercícios complementares. Recursos do nosso Componente O componente Favoritos será desenvolvido com alguns recursos. Vamos conhecer melhor o que são estes recursos e quais são as suas funções: - Query: Uma query é qualquer atividade que eu preciso executar no banco, o famoso CRUD: Criar, Ler, Atualizar, Deletar. Existem diferentes jeitos de chamar a query, dependendo do propósito: Select Query: executa um comando SQL, mas descarta o resultado. Usado apenas para testar se a conexão com o banco está ok. Não será usado no nosso exercício. Execute Query: executa um comando SQL que altera informações do banco. Pode ser um INSERT, UPDATE ou DELETE. Descarta os resultados. Iremos usar Execute Query para criar, alterar e excluir os favoritos. Select Cache Query: executa um comando SQL SELECT e armazena os resultados em um ResultSet. Este ResultSet retorna como resultado do serviço e pode ser manipulado em IDOC, Java ou outras linguagens. Iremos utilizar Select Cache Query para retornar a lista de favoritos de um usuário. - Service: Os serviços são os responsáveis por executar as queries (ou classes java, mas isso é papo para um outro tutorial...). O serviço recebe os parâmetros de entrada, executa a query e retorna o ResultSet (no caso de um SELECT). Os serviços podem ser executados através de templates, páginas IDOC, outras aplicações (através de API), ou diretamente na URL do browser. Neste exercício criaremos serviços para Criar, Editar, Deletar e Listar os favoritos de um usuário. - Template: Os templates são as interfaces gráficas (páginas) que serão apresentadas aos usuários. Por exemplo, antes de executar o serviço que deleta um documento do favoritos, quero que o usuário veja uma tela com o ID do Documento e um botão Confirma, para que ele tenha certeza que está deletando o registro correto. Esta tela pode ser criada como um template. Neste exercício iremos construir templates para os principais serviços, além da página que lista todos os favoritos do usuário e apresenta as ações de editar e deletar. Os templates nada mais são do que páginas HTML com scripts IDOC. A nossa sequência de atividades para o desenvolvimento deste componente será: - Criar a Tabela do banco - Criar o componente usando o Component Wizard - Criar as Queries para inserir, editar, deletar e listar os favoritos - Criar os Serviços que executam estas Queries - Criar os templates, que são as páginas que irão interagir com os usuários - Criar os links, na página de informações do conteúdo e no painel My Content Server Pois bem, vamos começar! Confira este tutorial na íntegra clicando neste link: http://blogs.oracle.com/ecmbrasil/Tutorial_Componente_Banco.pdf   Happy coding!  :-)

    In answering this question, I asserted that programming knowledge has a half-life of about 18 months. In physics, we have radioactive decay which is the process by which a radioactive element transforms into something less energetic. The half-life is the measure of how long it takes for this process to result in only half of the material to remain. A parallel concept might be that over time our programming knowledge ceases to be the current idiom and eventually becomes irrelevant. Noting that a half-life is asymptotic (so some knowledge will always be relevant), what are your thoughts on this? Is 18 months a good estimate? Is it even the case? Does it apply to design patterns, but over a longer period? What are the inherent advantages/disadvantages of this half-life? Update Just found this question which covers the material fairly well: "Half of everything you know will be obsolete in 18-24 months" = ( True, or False? )

  • How should I start with Lisp?

    - by Gary Rowe
    I've been programming for years now, working my way through various iterations of Blub (BASIC, Assembler, C, C++, Visual Basic, Java, Ruby in no particular order of "Blub-ness") and I'd like to learn Lisp. However, I have a lot of intertia what with limited time (family, full time job etc) and a comfortable happiness with my current Blub (Java). So my question is this, given that I'm someone who would really like to learn Lisp, what would be the initial steps to get a good result that demonstrates the superiority of Lisp in web development? Maybe I'm missing the point, but that's how I would initially see the application of my Lisp knowledge. I'm thinking "use dialect A, use IDE B, follow instructions on page C, question your sanity after monads using counsellor D". I'd just like to know what people here consider to be an optimal set of values for A, B, C and perhaps D. Also some discussion on the relative merit of learning such a powerful language as opposed to, say, becoming a Rails expert. Just to add some more detail, I'll be developing on MacOS (or a Linux VM) - no Windows based approaches will be necessary, thanks. Notes for those just browsing by I'm going to keep this question open for a while so that I can offer feedback on the suggestions after I've been able to explore them. If you happen to be browsing by and feel you have something to add, please do. I would really welcome your feedback. Interesting links Assuming you're coming at Lisp from a Java background, this set of links will get you started quickly. Using Intellij's La Clojure plugin to integrate Lisp (videocast) Lisp for the Web Online version of Practical Common Lisp (c/o Frank Shearar) Land of Lisp a (+ (+ very quirky) game based) way in but makes it all so straightforward

  • Welch's Juices-up Its Inventory Management with Oracle Supply Chain

    - by [email protected]
    Supply & Demand Chain Executive published recently a great success story about Welch's implementation of "Take Supply Chain and G.SI to work with Oracle Process Manufacturing". The company says it's been able to improve operational control, inventory accuracy, visibility and order fulfillment by automating its processes across three production/warehousing locations nationwide. Improving warehouse and inventory management operations creates efficiencies across a high-velocity nationwide supply chain Welch's production facilities were collecting more information than ever before on the flow of materials and inventory, but the company needed an effective and accurate method to organize and manage these data.   Article found at: http://www.sdcexec.com/publication/article.jsp?pubId=1&id=12256&pageNum=2

  • Chainload boot of Ubuntu installed on 32GB SD card from legacy Grub boot on USB

    - by Gary Darsey
    I have Ubuntu installed on a 32 GB SD card (in the Storage Expansion slot on an Acer Aspire One) with Grub2 installed in the same partition. I boot into legacy Grub on a USB drive and would like to boot by chainloading Grub2 from Grub (kernel/initrd or symlink booting would also be fine), but I haven't figured out how to do this from legacy Grub CLI. Output from blkid for this partition is /dev/mmcblk0p1: LABEL="Ubuntu" UUID="7ceb9fa7-238c-4c5d-bb8e-2c655652ddec" TYPE='ext4" / fdisk -lu information Boot indicator ID 83. Related entries in grub.cfg: search --no-floppy --fs-uuid --set-root 7ceb9fa7-238c-4c5d-bb8e-2c655652ddec linux /boot/vmlinuz-3.5.0-17-generic root=UUID=7ceb9fa7-238c-4c5d-bb8e-2c655652ddec... initrd /boot/initrd.img-3.5.0-17-generic I can't seem to replicate this in legacy Grub. Is there any way get Grub2 to chainload? How do I set root with UUID in legacy Grub? I prefer to boot from USB. Would Grub2 on USB (copying the grub.cfg generated during installation) be an option?
