• Using hreflang to specify a catchall language

  - by adam

  We have a site primarily targeted at the UK market, and are adding a US-market alternative. As per Google's recommendations: To indicate to Google that you want the German version of the page to be served to searchers using Google in German, the en-us version to searchers using google.com in English, and the en-gb version to searchers using google.co.uk in English, use rel="alternate" hreflang="x" to identify alternate language versions. Which gives us: <link rel="alternate" hreflang="en-gb" href="http://www.example.com/page.html" /> <link rel="alternate" hreflang="en-us" href="http://www.example.com/us/page.html" /> We do get enquiries from other areas of the world - particularly where there are expat communities (Dubai, UAE, Portugal etc). By adding the above tags, is there a risk that Google will only surface our site for UK and US search users? Do we need to specify a catch-all that will default all other searches to our UK site?

• Do subdomains need to be defined through domain registerar?

  - by Johnny

  I have bought a new domain name from GoDaddy. Let's say it is abcd.com. On GoDaddy's DNS Managing page, I changed A(Host) part to @ = 74.125.232.215 which is www.google.co.uk's IP address. Now if I type www.abcd.com, it directly goes to www.google.co.uk. But if I type http://test.abcd.com, it cannot be loaded. Do I need to define every subdomain through GoDaddy? Is this how it work? P.S. Amazon EC2 directly generates a subdomain for users to reach their virtual PCs. It cannot be domain registerar dependant. P.S.2. Same question for using "www2" at the start of url.

• Flex : Adobe veut faire don du SDK à l'open-source et crée la confusion dans sa communauté de développeurs

  Adobe veut faire don du SDK de Flex à l'open-source Et crée la confusion dans sa communauté de développeurs Le moins que l'on puisse dire est que la situation est confuse. Après avoir annoncé la fin de Flash dans l'univers des mobiles, Adobe vient de lancer une deuxième déclaration qui met ses développeurs en émoi : le SDK de Flex sera donné à la communauté open-source. Dans un premier temps, ce SDK sera confié à un organisme, baptisé Open Spoon Foundation, en partie chapeauté par Adobe. Le nom de cette fondation est un jeu de mot entre Spoon (cuillère) et Fork (fourchette), « fork » étant l'appellation usuelle pour des dé...
