In this article we suggest that otherwise unacknowledged histories of technological antagonism can help us (artists, activists, and researchers) to more deeply appreciate the foundations on which we develop activist resistances to contemporary computing. Departing from the case of Brazil, our goal is to bridge historical and contemporary perspectives by: (1) discussing the everyday practises of technological dissidence in the country, and how appropriation has been used to resist unequal power structures; (2) presenting how particular tactical ruptures in the history of art and media activism have sought to contaminate and re-envision networked technologies; (3) exploring the particular notions of algorithmic antagonism that two contemporary projects (PretaLab/Olabi and Silo/Caipiratech) advance, and how they relate to their historical counterparts. In sum, these different threads remind us that we’ve always been antagonistic, and that recognizing a longer genealogy of technological dissidences and ruptures can strengthen current practises against algorithmic oppressions.

在本文中，我们建议，否则未被承认的技术对抗历史可以帮助我们（艺术家、活动家和研究人员）更深入地了解我们发展激进主义抵制当代计算的基础。离开巴西的案例，我们的目标是通过以下方式连接历史和当代观点：（1）讨论该国技术异议的日常实践，以及如何使用拨款来抵制不平等的权力结构；(2) 展示艺术史和媒体激进主义的特殊战术断裂如何试图污染和重新构想网络技术；(3) 探索两个当代项目（PretaLab/Olabi 和 Silo/Caipiratech）推进的算法对抗的特定概念，以及它们与历史对应物的关系。总而言之，这些不同的线索提醒我们，我们一直是对立的，并且认识到技术分歧和破裂的更长谱系可以加强当前反对算法压迫的做法。
