Microsoft,Open Source and the software ecosystem: of predators and prey—the leopard can change its spots

Over the past few years, Microsoft has promoted a project called ‘Shared Source Initiative’, which allows certain customers (e.g., research institutions and independent software vendors) access to its source code on a restricted basis. As part of this initiative, Microsoft introduced some licences that appear to give unrestricted access to source code and closely resemble ‘traditional’ Open Source licences. In July 2007, two of these ‘shared source’ licenses (the Microsoft Community Licence and the Microsoft Permissive Licence) were submitted to the Open Source Initiative (OSI) and subsequently approved by the OSI as certified Open Source licences. Thus Microsoft's Shared Source Initiative and its partial embrace of Open Source appear to be a significant step towards closing the ideological rift between developers of proprietary software and the Free/Open Source software movement, and more than just another attempt to appease consumers and/or critics in terms of software transparency. By analysing the ‘evolution’ of Microsoft's Shared Source licences, this article aims to shed some light on the question what is needed for a ‘predator’ (i.e., proprietary, software developer) such as Microsoft to become ‘prey’ (i.e., be part of the Open Source community). This article concludes that, although Microsoft's efforts are to be lauded, it is highly unlikely that the company will embrace fully the Open Source philosophy in the near future.     

2011年4月份十大重要安全漏洞分析

2011年03月21日至4月20日,国家计算机网络入侵防范中心发布漏洞总条目为360条,漏洞总数比上月增加了5.26。其中威胁级别为＂紧急＂的有51条,＂高＂的有60条,＂中＂的有205条,＂低＂的有44条。威胁级别为＂紧急＂和＂高＂的漏洞占到总量的30.83,从漏洞利用方式来看,远程攻击的有274条,本地攻击的有86条,局域网攻击的有0条。可见,能够从远程进行攻击的漏洞占绝大多数,这使得攻击者利用相应漏洞发动攻击更为容易。4月微软发布17个安全公告,其中9个为严重等级,8个为重要等级,共修复Microsoft Windows、Microsoft Office、Internet Explorer、Visual Studio、.Net Framework和GDI＋（图形设备接口）中的64个漏洞。此外,Adobe也发布通告公布了Adobe Flash Player、Adobe Reader和Acrobat中发现的一个零日远程代码漏洞,该漏洞已被利用进行攻击。建议广大用户及时安装补丁,增强系统安全性,做好安全防范工作,保证信息系统安全。

Syntax Channelling and Other Issues affecting Innovation in the Graphical User Interface

Does the modern commercial Graphical User Interface constrain the developer of graphics applications into certain interaction styles? This paper looks at the Microsoft Windows environment as an example, with particular reference to the question of interaction modes, screen real-estate and visual appearance. The concept of syntax channelling is introduced to help analyse the problem of modality, and the question of button-down versus button-up dragging is debated in the context of a range of commercial applications, and possible consequences for upper limb disorder. A Windows application developed by the author involving the implementation of a variety of innovative interfacing techniques is presented.
