Manila y la gobernación de Filipinas en el mundo interconectado de la segunda mitad del siglo XVII
Full text link"Herrera Reviriego centra el foco en la gobernación de Manila y en especial en su acción diplomática y comercial en la región a lo largo de la segunda mitad del siglo xvii. Vemos enseguida cómo este proceso de gobernación manileña viene marcado tanto por su relación con las lógicas imperiales hispánicas como por su inserción en las dinámicas históricas asiáticas. Contemplar solo la parte del relato europeo, considerando a los asiáticos meramente como objetos del deseo (imperial o misional) o sujetos pasivos, y a lo sumo reactivos, respecto a la acción diplomática, evangelizadora o mercantil europea, no lleva a una comprensión cabal de buena parte de lo que sucedía. Veremos en este libro cómo las pautas de gobernación se fueron adaptando de forma posibilista a las evoluciones de sus entornos, y cómo su desarrollo tiene que ver con lo que pasa o se decide tanto en la península o en Nueva España como en Manila, o en Japón, o en Fujian"

Cuckoo Filters and Bloom Filters: Comparison and Application to Packet Classification
Full text linkBloom filters are used to perform approximate membership checking in a wide range of applications in both computing and networking, but the recently introduced cuckoo filter is also gaining popularity. Therefore, it is of interest to compare both filters and provide insights into their features so that designers can make an informed decision when implementing approximate membership checking in a given application. This article first compares Bloom and cuckoo filters focusing on a packet classification application. The analysis identifies a shortcoming of cuckoo filters in terms of false positive rate when they do not operate close to full occupancy. Based on that observation, this article also proposes the use of a configurable bucket to improve the scaling of the false positive rate of the cuckoo filter with occupancy.Pedro Reviriego and David Larrabeiti would like to acknowledge the support of the ACHILLES project PID2019-104207RB-I00 and the Go2Edge network RED2018-102585-T funded by the Spanish Ministry of Science and Innovation and of the Madrid Community research project TAPIRCM grant no.

Recovery of parliamentary chronicle during the Spanish Democratic Transition: the chronicles of Victor Marquez Reviriego
Full text linkPublicados en la revista Triunfo entre 1977 y 1981, los ‘Apuntes parlamentarios’ de Víctor Márquez Reviriego constituyeron un testimonio de especial relieve para conocer el desarrollo de las recién estrenadas Cortes democráticas en España. Tras cuarenta años de dictadura, este periodista, junto a otros compañeros de profesión, retomó la crónica parlamentaria, una modalidad periodística que permanecía olvidada en las hemerotecas, a pesar de haber contado con notable prestigio en la prensa española desde el siglo XIX. Autores como Andrés Borrego, Azorín, Wenceslao Fernández Flórez o Josep Pla habían destacado anteriormente en esta parcela del periodismo, que combina la precisión informativa y la creatividad literaria. Este artículo describe la aportación de Víctor Márquez Reviriego al revival de la crónica parlamentaria, al tiempo que analiza los principales temas abordados en su obra.Published in the magazine Triunfo between 1977 and 1981, the ‘Apuntes parlamentarios’ of Víctor Márquez Reviriego were a testimony of particular importance for the development of democratic Cortes recently premiered in Spain. After forty years of dictatorship, this journalist, along with other colleagues, resumed parliamentary chronicle a journalistic mode remained forgotten in libraries, despite having enjoyed considerable prestige in the Spanish press since the nineteenth century. Authors like Andrés Borrego, Azorín, Wenceslao Fernández Flórez or Josep Pla had highlighted earlier in this piece of journalism, combining the accuracy of information and literary creativity. This article describes the contribution of Victor Marquez Reviriego the revival of parliamentary chronicle, while analyzing the main stylistic features of his work
Less-is-Better Protection (LBP) for memory errors in kNNs classifiers
Full text linkClassification is used in a wide range of applications to determine the class of a new element; for example, it can be used to determine whether an object is a pedestrian based on images captured by the safety sensors of a vehicle. Classifiers are commonly implemented using electronic components and thus, they are subject to errors in memories and combinational logic. In some cases, classifiers are used in safety critical applications and thus, they must operate reliably. Therefore, there is a need to protect classifiers against errors. The k Nearest Neighbors (kNNs) classifier is a simple, yet powerful algorithm that is widely used; its protection against errors in the neighbor computations has been recently studied. This paper considers the protection of kNNs classifiers against errors in the memory that stores the dataset used to select the neighbors. Initially, the effects of errors in the most common memory configurations (unprotected, Parity-Check protected and Single Error Correction-Double Error Detection (SEC-DED) protected) are assessed. The results show that surprisingly, for most datasets, it is better to leave the memory unprotected than to use error detection codes to discard the element affected by an error in terms of tolerance. This observation is then leveraged to develop Less-is-Better Protection (LBP), a technique that does not require any additional parity bits and achieves better error tolerance than Parity-Check for single bit errors (reducing the classification errors by 59% for the Iris dataset) and SEC-DED codes for double bit errors (reducing the classification errors by 42% for the Iris dataset).S.

When filtering is not possible caching negatives with fingerprints comes to the rescue
No full textBloom filters are widely used in networking to accelerate checks and in particular to avoid accessing slow memories when a match will not be found. Unfortunately, filtering requires several on-chip memory bits per element and thus when the tables are large and the on-chip memory small is not applicable. In those cases, caching the most frequently accessed elements on-chip seems the only viable option. However, the key is typically formed by several packet header fields, which means that each cache entry consumes a significant amount of on-chip memory bits. In this paper, an efficient scheme to cache negatives, that is elements that will not find a match on the table is presented. In more detail, the proposed scheme enables the caching of negatives using less than 16 bits per entry regardless of the size of the key. This translates to a reduction of at least 6x in the size of the cache when used for example flow tracking
Perfect cuckoo filters
No full textBloom filters and cuckoo filters are used in many applications to reduce the amount of memory needed to check if an element belongs to a set. The main drawback of these filters is that with low probability, a positive is returned for an element that is not in the set. Recently, the concept of Bloom filters with a false positive free zone has been introduced showing that false positives can be avoided when the universe from which elements are taken and the number of elements inserted in the filter are both small. Unfortunately, this limits the use of such false positive free Bloom filters in many practical applications. In this paper, a false positive free, i.e. perfect, cuckoo filter is presented and evaluated. The proposed design supports universe sizes of billions of elements and stores millions of elements, making it practical for a wide range of applications. The perfect cuckoo filter can be also used to perform mapping, further extending the range of scenarios in which can be used. The benefits of the proposed perfect cuckoo filter are illustrated with two case studies: IP address blacklisting and longest prefix match for IP forwarding
