All About Bitmap Indexes... And Sorting ThemDaniel Lemire
A review of bitmap index from an academic perspective. Several theoretical results are presented. The talk also discuss technical issues regarding sorting the tables prior to indexing, as a way to improve the indexes.
Much of the talk is based on the following preprint:
Daniel Lemire, Owen Kaser, Kamel Aouiche, Sorting improves word-aligned bitmap indexes.

How can your business prevent the oceans from having more plastic than fish i...GA Circular
Though the oceans cover about 71% of the earth’s surface, we’ve only explored less than 5% of it. Most of us are only barely aware of the enormity and scale of the waters we live surrounded by. We are on the precipice of global climate change, and it’s up to the world’s businesses to lead the way in making a positive impact on our oceans. And to top it off, using our oceans sustainably is increasingly being shown to make good business sense.
In creating this report, we’ve brought together the latest from around Asia on breakthrough technologies, grassroots movements, and large multinational muscle coming together to improve seafood security, reduce the impact of plastic waste on our waters, and promote the livelihoods of the millions of smallholders across Asia who depend on the oceans for survival. We hope the stories featured here inspires your business to start playing an active role in this movement and further your growth as a purpose-driven organisation.

ABOUT THE PRESENTATION BELOW
Success in Asia is highly attractive, and fraught with challenges. What works in Western markets doesn't always apply to audiences in China. These markets ranging from the highly sophisticated, like Shanghai and Beijing, to those with 'Tier 3' millionaires who lack international experience.
This presentation covers surprising statistics on China and the pitfalls for foreign brands who fail to plan their China approach.

Growing number of wireless devices nowadays often results in congestion of wireless channels. In research, this topic is referred to as networking in dense wireless spaces. The literature on the topic shows that the biggest problem is the high number of concurrent sessions to a wireless access point. The obvious solution is to reduce the number of concurrent sessions. This paper proposes a simple method called Bulk-n-Pick which minimizes the number of prolonged concurrent sessions by separating bulk from sync traffic. Aiming at educational applications, under the proposed design web applications would distribute the main bulk of content once at the beginning of a class and then rely on small messages for realtime sync traffic during the class. For realistic performance analysis, this paper first performs real-life experiments with various counts of wireless devices, bulk sizes and levels of sync intensity. Based on the experiment, this paper shows that the proposed Bulk-n-Pick method outperforms the traditional design even when only two concurrent bulk sessions are allowed. The experiment shows that up to 10 concurrent bulk sessions are feasible in practice.
