The materiality of typescripts in Pedro Homem de Mello’s writing practice

This article addresses the main typewriting habits of Portuguese poet Pedro Homem de Mello (1904–1984), as evidenced in documents belonging to the family’s private estate and scattered collections owned by public archives and libraries. After examining his work in several spheres of activity (his personal and professional correspondence, his newspaper collaborations and essays as a folklorist, and his work as an author and presenter of TV and radio programs), the essay focuses on material aspects of Homem de Mello’s literary typescripts, such as page management strategies, the use of coloured ribbons, the occurrence of mechanical errors, or the combination of handwritten corrections and carbon-paper duplicators as a favoured revision technique. It concludes by interrogating how the author’s multimodal typewriting ecosystem may have contributed to stylistic changes in his poetry, catalysing freer modes of expression in the traditional forms of his choice.

Code Generator Development to Transform IFML (Interaction Flow Modelling Language) into a React-based User Interface

Model-Driven Software Engineering (MDSE) is a software development approach that uses the Model to be the main actor of the development. MDSE can be applied to User Interface (UI) Development so that a model for the UI can be built, and then a transformation can be made to turn it into a running application. In this research, we develop UI Generator to support UI Development with the MDSE approach. This UI Generator can also support UI Development in Software Product Line Engineering (SPLE) paradigm. The UI is modeled with Interaction Flow Modeling Language (IFML) diagram. Then The IFML diagram is transformed into React-Based UI by the UI Generator. The UI Generator is developed with Acceleo on Eclipse IDE to transform IFML into React Code with the transformation rules defined in this research. The UI generator is also enriched with display settings and static page management to address user customization needs. The experimental results show that the UI Generator can generate a functional website. Besides evaluating the working product, UI Generator is evaluated qualitatively well based on six quality criteria as an SPLE supporting tool.

Hardware-Software Collaborative Tiered-Memory Management Framework for Virtualization

The tiered-memory system can effectively expand the memory capacity for virtual machines (VMs). However, virtualization introduces new challenges specifically in enforcing performance isolation, minimizing context switching, and providing resource overcommit. None of the state-of-the-art designs consider virtualization and address these challenges; we observe that a VM with tiered memory incurs up to a 2× slowdown compared to a DRAM-only VM. We propose vTMM , a hardware-software collaborative tiered-memory management framework for virtualization. A key insight in vTMM is to leverage the unique system features in virtualization to meet the above challenges. vTMM automatically determines page hotness and migrates pages between fast and slow memory to achieve better performance. Specially, vTMM optimizes page tracking and migration based on page-modification logging (PML), a hardware-assisted virtualization mechanism, and adaptively distinguishes hot/cold pages through the page “temperature” sorting. vTMM also dynamically adjusts fast memory among multi-VMs on demand by using a memory pool. Further, vTMM tracks huge pages at regular-page granularity in hardware and splits/merges pages in software, realizing hybrid-grained page management and optimization. We implement and evaluate vTMM with single-grained page management on an Intel processor, and the hybrid-grained page management on a Sunway processor with hardware mode supporting hardware/software co-designs. Experiments show that vTMM outperforms existing tiered-memory management designs in virtualization.

CPP: A lightweight memory page management extension to prevent code pointer leakage

Protecting code pointers (e.g., return address, function pointer) from leakage is desirable from a security perspective. Isolation mechanisms have been the favored candidate to protect code pointers. However, these mechanisms result in significant performance overhead as they need to instrument extra instructions for frequent permission switching or bound checking. In this paper, we propose CPP, a novel Code Pointer-only Memory Page Management to restrict attack-critical operations for code pointers by hardware. Our hardware–software co-design allows CPP mark code pointers at page granularity that requires minor hardware modification. CPP checks the legality of their operations in parallel with instruction execution. We implement a prototype system and our evaluation shows CPP can effectively mitigate the code pointer leakage attacks with less than 2.1% performance overhead.

Impact of brands' Facebook page characteristics and followers' comments on trust building and purchase intention: Alternative attractiveness as moderator

AbstractDrawing on signaling theory, this research aims to examine the impact of brands' Facebook page characteristics (information variety, information currency, and responsiveness) and followers' comments on building trust and its consequent effect on purchase intention by considering attractiveness of alternatives as a moderator. Data were obtained from 396 brands' Facebook page followers in Malaysia using an online survey and analyzed using the partial least squares technique. The results indicated that a brand's Facebook page information variety and information currency significantly affect trust in that brand. Additionally, responsiveness and followers' positive comments on the Facebook page were found to have a significant influence on both trust in brand and trust in product. Furthermore, both trust in brand and trust in product were significantly related to intention to purchase. Our results revealed that alternative attractiveness negatively moderates the influence of trust on purchase intention. The findings extend the literature by illustrating that (i) the influence of customer‐generated information on trust is higher than the influence of company‐generated information; (ii) the determinants and impacts of trust in brand and trust in product are different; and (iii) existence of attractive alternatives may offset the impact of trust in brand on purchase intention. The findings are useful for brand managers and enable them to influence customers' trust through successful management of brands' Facebook fan pages.

МАРКЕТИНГОВЫЕ ФАКТОРЫ, ОПРЕДЕЛЯЮЩИЕ ПОТРЕБИТЕЛЬСКОЕ ПОВЕДЕНИЕ ПОКОЛЕНИЯ Z

The concept of «Industry 4.0», which is actively developing in Russian companies, involves the end-to-end digitalization of assets and their integration into the digital ecosystem, developing the chain of creating the actual value of a product (service). As digital ecosystems develop, marketing, including strategic marketing, is also being modernized. SMM is being transformed from «page management in social networks» to one of the main marketing tools of our time. The choice of social platforms for the company’s presence is an important moment in the formation of the SMM-strategy. Companies implementing SMM should create optimal marketing content that will strengthen relationships with consumers and ensure not only long-term and favorable communications, but also create sustainable results in the activities of companies. Today, more than 25% of the working-age population of Russia is accounted for by generation Z, which has replaced millennials, which has its own characteristics and specifics of consumer behavior. For a deeper understanding of Generation Z consumers, the authors conducted a study of the factors that influence the model of consumer behavior in the B2C market.

Ciberactivismo: Elemento articulador del Movimiento Indígena del Cauca, Colombia

The internet has contributed to the increasing use of politics and activism on the networks by social groups. In this article, a contextualization of the use of social networks and web platforms is made as an articulating element of the Association of Indigenous Cabildo del Norte del Cauca (Cxhab Waka Kiwe), of which the Indigenous Movement of Cauca is part, to give to know their political and social needs in the Colombian public sphere. The theoretical basis was Dahlgren's (2005) conceptualization of the internet in the public sphere, and Sampedro's (2005) of cyberactivism. Likewise, the methodology of analysis of social networks is worked out by making a description of the elements that operate within these, referring to social mobilization. As a result, digital channels have served them to publicize the problems of displacement, land theft and others. They have also opened up opportunities for them to favor political proselytism and promote it through the management of social networks and web pages. It is concluded that cyberspace opens the possibility for organizations or social movements to reduce the exclusion to which they have been historically exposed.

Memory management technology based on homegrown multicore processor

Many crucial technologies in modern computer systems need innovation due to the increasing number of CPU cores and the growing trend of heterogeneous platform features. With the development of heterogeneous storage technology, the traditional page memory management performance overhead issue becomes more and more prominent. Segment memory management is widely used in homegrown multicore processors, but how to improve its flexibility and usability still confront challenges. In order to cope with this case, this paper proposed a segment-page-combined memory management technique based on domestic multicore processor. This technology realizes the fusion management of page and segment in homemade node level operating system, effectively solves the performance problem of page management, and improves the usability of segment management.

Interhost Orchestration Platform Architecture for Ultrascale Cloud Applications

Cloud data centers exploit many memory page management techniques that reduce the total memory utilization and access time. Mainly these techniques are applied to a hypervisor in a single host (intra-hypervisor) without the possibility to exploit the knowledge obtained by a group of hosts (clusters). We introduce a novel interhypervisor orchestration platform to provide intelligent memory page management for horizontal scaling. It will use the performance behavior of faster virtual machines to activate prefetching mechanisms that reduce the number of page faults. The overall platform consists of five modules-profiler, collector, classifier, predictor, and prefetcher. We developed and deployed a prototype of the platform, which comprises the first three modules. The evaluation shows that data collection is feasible in real-time, which means that if our approach is used on top of the existing memory page management techniques, it can significantly lower the miss rate that initiates page faults.

When Storage Response Time Catches Up With Overall Context Switch Overhead, What Is Next?

The virtual memory technique provides a large and cheap memory space by extending the memory space with storage devices. It applies context switch to asynchronously swapping pages between memory and storage devices for hiding the long response time of storage devices when a page fault occurs. However, the overall context switch overhead is high because the context switch itself is a complex function and would further incur TLB shootdown/flush and compulsory CPU cache misses after context switches. On the contrary, as the rapid responsiveness improvement of high-end storage devices, we observe that the response time of high-end storage devices catches up and gradually becomes smaller than the overall context switch overhead. At this turning point, to further enhance the system responsiveness, we advocate adopting synchronous swapping rather than context switch in response to page faults. Meanwhile, we propose a strategy, called shadow huge page management, to further improve the overall system performance by minimizing the overall time overheads caused by page faults and page swappings. Evaluation results show that the proposed system can efficiently reduce the total CPU wasting time.

Investigating Brand Page Engagement in the SNS Marketing Context

Customer engagement has been the main objective of brand companies in their marketing through social networking sites (SNS). Facebook is the most popular platform for SNS marketing, especially for companies that try to engage with their customers by providing various values through their brand pages (i.e., brand communities). The management of brand pages, therefore, becomes “the means” by which to achieve the result (“the end”) of SNS marketing, and visitors to the brand pages (i.e., brand communities) then come to have a favorable attitude toward the brand. Based on a “means–ends” framework, this study examines the development of engagement between customers and brands in terms of brand page engagement as the means objective and brand attitude as the ends objective in the context of Facebook. This study further examines the antecedents and consequences of brand page engagement based on the customer value theory with two-stage data collection. This study contributes to the literature by explaining the roles and effects of brand page engagement in SNS marketing. This study further provides guidance to SNS providers and practitioners on SNS marketing strategies.

The Role of Brand Page Experiences on Consumer Engagement in Social Media

This study develops and empirically tests a comprehensive model of consumers'' brand page experiences that illuminates dynamics among perceived values (practical value, stimulation, enjoyment, and social identification), brand page engagement dimensions (cognitive engagement, affective engagement, and behavioral engagement) and brand loyalty. An online survey was employed for data collection. We collected 358 usable responses for data analysis. Structural equation modeling results show that three dimensions of perceived values (practical value, perceived enjoyment, and social identification) positively affect brand engagement dimensions, while perceived stimulation affects affective engagement only. As for the roles of brand page engagement, affective and behavioral engagement positively influence brand loyalty. This study demonstrates how consumers'' perceived values of brand page experience influence each dimension of brand page engagement and how each dimension has a different impact on brand loyalty. The results of this study provide substantive contributions to the consumers'' brand page experience and engagement literature and brand page management on social media for developing brand loyalty.

Exploring firms’ fan page behavior and users’ participation: evidence from airline industry on Twitter

ABSTRACT Firms motivate users to enhance their fan page engagement. Existing research has thus far concentrated on firms’ fan page management strategies which lead to different results in terms of numbers of followers and followings and the rate of users’ participation. Drawing on the insights of Social Practice Theory and Uses and Gratification Theory (UGT), we aim to examine firms’ strategies in relation to users’ activities on fan pages, and the methods firms utilize for content management of their fan pages. Our empirical study consisted of a sample of 36 prominent airlines in the world. We applied an exploratory mixed method to analyze the data obtained from a set of 153,992 postings (including tweets, retweets, and replies) which were published on the airlines’ fan pages. Our results showed that firms’ behavior from two perspectives of fan page strategy and content management has a significant relationship with users’ participation.

Footprint-Based DIMM Hotplug

Power-efficiency has become one of the most critical concerns for HPC as we continue to scale computational capabilities. A significant fraction of system power is spent on large main memories, mainly caused by the substantial amount of DIMM standby power needed. However, while necessary for some workloads, for many workloads large memory configurations are too rich, i.e., these workloads only make use of a fraction of the available memory, causing unnecessary power usage. This observation opens new opportunities for power reduction by powering DIMMs on and off depending on the current workload. In this article, we propose footprint-based DIMM hotplug that enables a compute node to adjust the number of DIMMs that are powered on depending on the memory footprint of a running job. Our technique relies on two main subcomponents—memory footprint monitoring and DIMM management—which we both implement as part of an optimized page management system with small control overhead. Using Linux's memory hotplug capabilities, we implement our approach on a real system, and our results show that our proposed technique can save 50.6–52.1 percent of the DIMM standby energy and the CPU+DRAM energy of up to 1.50 Wh for various small-memory-footprint applications without loss of performance.

Software TLB Management Method Based on Balanced Binary Tree

Abstract Purpose: with the development of the computer system, there is a higher request to reduce the failure times of Translation Look—aside Buffer and relieve the failure influence, normal solution is deal with TLB failure by software or hardware, it find the page table and then implement the index operation to locate the page want. Method: In order to satisfy the needs of software management method for mapping speed from virtual address to physical address and to expand the size of TLB, our team design a software management method based on balanced binary search tree. Page management is implemented in software management, TLB is managed by operating system based on abstract model, and MMU (memory management unit) is no longer used Unit, our team build a balanced binary tree to search TLB. Result: Binary search tree has the advantage of pruning in the interval search problem under the balanced state. Therefore, searching TLB by this method is conducive to the expansion of TLB capacity, making space for cache and other performance improvement designs on chip and reducing costs. However, the search speed is reduced and some time is sacrificed to free up CPU space. Conclusion: This method can free up CPU design space, also can expand more size of TLB and reduce the cost, its optimization algorithm is worthy of further research.

A quantitative evaluation of unified memory in GPUs

The introduction of unified memory and demand paging has simplified programming of graphics processing units (GPUs). It has also enabled oversubscribing the memory for a GPU. However, the overhead of page management makes page faults a performance bottleneck. Sometimes the page eviction policy is unable to mitigate performance slowdown caused by page faults and memory oversubscription. On average, eviction policies such as Random and CAR are not competitive with a traditional least recently used (LRU) policy. Other policies, such as CLOCK-Pro, are designed to overcome challenges with LRU, but they only achieve limited speedup. Even enhancing LRU with page walk hit information does not lead to notable performance improvement. Based on these observations, we propose optimization opportunities to mitigate performance degradation caused by page faults and memory oversubscription. These optimization opportunities include an effective page eviction policy that retains LRU’s advantages while addressing LRU’s inability to deal with thrashing access patterns, page prefetch and pre-eviction, memory-aware throttling, and capacity compression.

UniBuffer: Optimizing Journaling Overhead With Unified DRAM and NVM Hybrid Buffer Cache

Journaling techniques play an important role in addressing the reliability issue of filesystems caused by the volatile dynamic random access memory (DRAM)-based buffer cache. However, journaling techniques introduce a large number of extra storage writes, which greatly degrades system performance, especially for mobile devices. Emerging nonvolatile memory (NVM) technologies bring a new perspective of solving the write amplification issue caused by journaling. By adopting NVM as the buffer cache, the committed data can be maintained in NVM before being written back to the storage, thus, eliminating the journaling overhead. However, simply utilizing NVM as the buffer cache suffers from the limited lifetime and the relatively longer write latency of NVM. In this paper, we present a hybrid buffer cache architecture, named UniBuffer, by combing NVM with dynamic random access memory (DRAM) to reduce the journaling overhead and overcome the inherent constraints of NVM. In UniBuffer, we first propose a journaling-aware page management (JAPM) policy to smartly allocate data to DRAM and NVM pages. JAPM puts infrequently updated data in NVM to reduce the journaling overhead and frequently updated data in DRAM to improve the write performance and lifetime of the hybrid buffer cache. In addition, since data in one journaling transaction may be dispersed in NVM and DRAM simultaneously, different committing policies are required for different storage media, respectively. In order to guarantee the atomicity of the transaction execution in the hybrid cache architecture, a partial in-place commit (PIPC) journaling scheme is proposed to coordinate different committing patterns for NVM and DRAM. We have implemented the proposed techniques on Linux 3.14.52 and measured the performance with representative I/O-intensive benchmarks. The experimental results show that our scheme effectively improves the I/O performance compared with the ext4 filesystem and prolongs the lifetime of the hybrid buffer cache compared with the union of buffer cache and journaling (UBJ) scheme.
