  1. Hello Vicente, Ina ganin cewa ana iya amfani da ku a Windows 7.

    Akwai wani abu da ka rasa game da xP?
    Akwai dalilai da yasa ba zan dawo zuwa XP ba?

  2. Windows 7 a cikin 64bit har yanzu yana baku damar shigar da aikace-aikace a cikin 32bit ... Kuma har yanzu babu ɗayan aikace-aikacen GIS ɗina da ya daina aiki.

  3. "Af, kun gwada Manifold akan 64-bit?"

    Nup…. Kodayake PC dina mai ƙasƙanci yana da 64-bit AMD, ban so in girka Windows 64 azaman tarin aikace-aikace kuma direbobi ba su da amfani. Ina tsammanin matakin zai zama a sami keɓaɓɓen PC kuma shigar da komai a cikin 64bits.

    Ina da babu shakka cewa da yawa zama daya daga cikin wadanda aikace-aikace da zai gudu a karkashin 64 su bambancin ragowa, kuma ba za a mere adapatación amma zai cire ruwan 'ya'yan itace (kamar yadda suka yi da GPU CUDA fasaha).
