Enhancing Site Reliability Engineering (SRE) Observability: A Comprehensive Approach

The subject of applying software engineering techniques to IT operations to create scalable and highly reliable software systems is known as site reliability engineering, or SRE for short. To preserve system’s health, it heavily emphasizes automation, ongoing improvement, and efficient incident response. Observability, is the tracking and examination of system outputs in the form of metrics, logs, and traces with the goal of providing insight into the system's internal state, is one of the fundamental principles of SRE. This keeps systems reliable and effective by enabling the early detection and resolution of problems. SRE and observability work together to help businesses achieve high IT operations performance and reliability. The contemporary IT environment is becoming more and more complex as industries growing infrastructure use on-premises and cloud hosting, adding microservice design along with traditional monolithic application architectures. In the pursuit of observability, this diversity presents unique difficulties for SRE. This article sheds light on the significance of SRE observability, tools and tactics used by enterprises, and how site reliability engineering could be improved across numerous industries with the use of an open-source framework like Open Telemetry to strengthen observability.

Improving Tourism Village Quality through the Development of the Geotrail in Genggelang Village, Rinjani-Lombok UGGp. Area

Abstract Rinjani-Lombok UGGp has a geological heritage in the form of traces of the Samalas Eruption in 1257, which are dispersed among 22 geological sites. One of them is the Waterfall in Gangga Geosite at Genggelang Village, which is part of the geopark’s main geotrail namely ‘Rinjani Cultural Landscape’. Genggelang itself is one of 99 tourism villages in West Nusa Tenggara Province, where the geosite is the main attraction. This tourism village was actually being developed to become a sustainable tourism village. Unfortunately, the earthquake in 2018 had a tremendous impact on North Lombok Regency, including Genggelang Village. In addition to the loss of lives and property, the earthquake had enormous losses economic impact, particularly on North Lombok’s tourism industry. Tourism in this village has yet to revive, thus innovative efforts are required to market Genggelang as an attractive tourism destination. One of the initiatives made is to integrate village’s potential, including its primary geotourism attractions and create an interesting geotrail. This geotrail can serve as the foundation for developing geotour packages and action plans for tourism development. The methods employed include focus group discussion, in-depth interviews with Genggelang figures and field surveys. According to the findings of the study, there are eleven appropriate key attractions for usage in the geotrail. The main attractions include geological features, biodiversities and prominent community culture. Some of them include Waterfall in Gangga Geosite, coffee and chocolate, and the village museum. The SWOT analysis reveals that Genggelang has a broad village potential, some of which have been highly valued nationally. Furthermore, the village’s proximity to 3 Gili and located in the geopark area provide opportunities for further development. However, human resources and the threat of disasters are the most pressing issues in Genggelang. So, the construction of this geotrail must be followed by the implementation of short and long-term action plans. This action plan necessitates the participation of relevant stakeholders.

Rituals Aswameda in the text description he has not been punished is part of the great ceremony carried out by Yudistira in the text Aswamedapara as an effort to ask for forgiveness and atonement for the murder he committed against his relatives in the war Bharatayuda. This ritual is marked by the release of horses escorted by selected soldiers across other kingdom areas. Regions that recognize the authority of Hastinapura will allow horses to pass, whereas regions that try to block them will be resolved by war. Ritual procession Aswameda It looks like a show of power but it's true This ritual emphasizes alms primarily to clergy and other forms of ceremonial offerings. This research uses the literature study method which is directed at searching for data through documents that support the research process. The theories used are structural theory and reception theory. The results of this research will be a reflection of life in the form of traces of past culture reflected in literary works.

Образ детства в повествовательной структуре мемуарно-автобиографической прозы (Ф. Р. де Шатобриан и Жорж Санд)

The article considers the theme of childhood and the specific features of its representation in the Mémoires d’outre-tombe by F. R. de Chateaubriand and Histoire de ma vie by Georges Sand. Childhood is seen as an integral structural element of the self-narrative, the artistic concept of which is formed in the context of the era and the existing literary tradition. The conceptualization of the mechanisms of this process seems to be important from the perspective of literary studies, as it allows us to reveal the variety of forms of Romantic worldview and trace their dynamics. The comparative analysis of texts created by authors who belong to different literary generations and represent the extremes of the French Romantic tradition in their work is aimed at exploring the mechanisms and individual features of the childhood representation within the framework of the narrative model developed under the influence of Romanticism. The comparison of the two author’s concepts of childhood reveals the general Romantic dominant perception of this phenomenon, demonstrates the evolution of views on the child in the culture of the first half of the 19th century, and also reveals the specific nature of memoirists’ self-perception expressed in the techniques of recreating childhood. It is shown that Chateaubriand’s portrayal of childhood is focused exclusively on his own, in his opinion, unique experiences that allow him to identify in a child the outlines of the future “son of the century”, a lonely and frustrated wanderer, while for George Sand her personal experience becomes the material for analyzing the phenomenon of childhood itself. Using the material of her own memories, she creates both a deeply intimate and psychologically convincing image of childhood, thereby expanding the palette of topoi formed by her predecessors and forestalling the discoveries of age psychology. This study allows us to conclude that the two narrative models, while retaining the general Romantic tendency to mythologize childhood, also distinctly record the transition from the marked egocentrism and introspection of the older generation of Romantics to the overcoming of individualism and searching for new narrative strategies among writers who worked at a later stage of French Romanticism and were influenced by new aesthetic, philosophical and social concepts.

The Internet as an object of study of criminalistics science

Relevance. The Internet acts as an object accumulating a large array of results of user actions in the form of electronic and digital traces, as well as a significant amount of other information that can be used in the investigation of crimes.

Insights into pharmaceutical co-crystallization using coherent Raman microscopy

Formulating active pharmaceutical ingredients (APIs) as co-crystals requires a thorough understanding of co-crystallization behavior under different process conditions. This study employs two forms of coherent Raman microscopy, narrowband coherent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS) with spectral focusing, to study co-crystallization via liquid-assisted ball milling. Indomethacin and nicotinamide served as the model API and co-former, and the results were compared with established analytical methods. Narrowband CARS, with univariate peak position analysis, was useful to visualize co-crystal formation, but suffered some degree of signal mixing that affected component identification. Hyperspectral SRS imaging, combined with classical least squares multivariate analysis, separated the different components with high confidence and proved to be a robust and rapid tool to qualitatively and quantitatively image co-crystallization. The coherent Raman imaging results explained divergent co-crystallization endpoints obtained with the conventional solid-state analysis methods. CARS and SRS microscopies also revealed the presence of otherwise undetected trace forms. Finally, we also demonstrated the dramatic reversal of partial co-crystal formation during milling, depending on ethanol content. Overall, the study demonstrates the added value coherent Raman microscopy can provide for analysis of co-crystallization processes.

Comparison of nonarchimedean and logarithmic mirror constructions via the Frobenius structure theorem

AbstractFor a log Calabi Yau pair () with smooth affine, satisfying either a maximal degeneracy assumption or contains a Zariski dense torus, we prove under the condition that D is the support of a nef divisor that the structure constants defining a trace form on the mirror algebra constructed by Gross–Siebert are given by the naive curve counts defined by Keel–Yu. As a corollary, we deduce that the equality of the mirror algebras constructed by Gross–Siebert and Keel–Yu in the case contains a Zariski dense torus. In addition, we use this result to prove a mirror conjecture proposed by Mandel for Fano pairs satisfying the maximal degeneracy assumption.

Making Sense of Multi-threaded Application Performance at Scale with NonSequitur

Modern multi-threaded systems are highly complex. This makes their behavior difficult to understand. Developers frequently capture behavior in the form of program traces and then manually inspect these traces. Existing tools, however, fail to scale to traces larger than a million events. In this paper we present an approach to compress multi-threaded traces in order to allow developers to visually explore these traces at scale. Our approach is able to compress traces that contain millions of events down to a few hundred events. We use this approach to design and implement a tool called NonSequitur. We present three case studies which demonstrate how we used NonSequitur to analyze real-world performance issues with Meta's storage engine RocksDB and MongoDB's storage engine WiredTiger, two complex database backends. We also evaluate NonSequitur with 42 participants on traces from RocksDB and WiredTiger. We demonstrate that, in some cases, participants on average scored 11 times higher when performing performance analysis tasks on large execution traces. Additionally, for some performance analysis tasks, the participants spent on average three times longer with other tools than with NonSequitur.

Geochemical Evaluation of Itakpe Iron Ore Mine Tailings, Itakpe, Nigeria

The study focus on the characterisation of the tailings attributes with a view to understanding the geotechnical properties, leaching potential and possible major oxides. The samples were composited into five. The composited samples were subjected to both physical and chemical tests. The physical tests include particle size distribution, specific gravity, density, residual humidity and Atterberg limits. The chemical tests include pH, organic matter, and Energy Dispersive X-Ray Fluorescence Spectrometry (ED-XRFS). Mineralogical analyses were also carried out on the composited samples using the Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-ray Spectroscopy (SEM-EDX). The results from the physical tests show that the tailings are mostly fine-medium sands, having high specific gravity and bulk density, with low residual humidity. The chemical analyses show that the tailings are weakly acidic and neutral with low organic matter. The energy dispersive x-ray fluorescence spectroscopy analysis of the samples shows that they contain high concentrations of Fe2O3, SiO2, and other trace compounds. The Fe2O3 of the samples ranged from 15.03 to 20.12% and SiO2 ranged from 57.26 to 60.10%. SEM micrographs obtained revealed the interlocking nature of the minerals constituting the ore matrix. EDX analysis of the regions within the ore matrix revealed the presence of Si, Fe, Al, K, Ca, Nb, Y, Ag, Zn, Mg, Cl, P, S, Na, Ti, Zr; such that silicon and iron are the major elemental constituents of the ore matrix while other elements exists in trace form.

Witt invariants of Weyl groups

We describe the Witt invariants of a Weyl group over a field k0 by giving generators for the W(k0)-module of Witt invariants, under the assumption that the characteristic of k0 does not divide the order of the group. For the Weyl groups of types Bn, Cn, Dn, and G2, we show that the Witt invariants are generated as a W(k0)-algebra by trace forms and their exterior powers, extending a result due to Serre in type An. Many of our computational methods are applicable to computing Witt invariants of any smooth linear algebraic group over k0, including a technique for lifting module generators from cohomological invariants to Witt invariants.

Evaluation of the Sragi Secondary Channel of the Kaliwadas Irrigation Area, Pekalongan Regency

The Sragi secondary channel is located in the Kaliwadas irrigation area, Pekalongan Regency has a length of 7,587 m. The position of the channel is in a rice field area which is used to optimize irrigation to support agricultural business productivity. The existing condition of the channel in the form of native soil causes frequent leaks. Technical handling is needed to repair irrigation buildings in the form of a study on the existing condition of the Sragi secondary channel through field surveys and checking physical conditions. Furthermore, identification of the level of damage to irrigation channels is carried out. From the problems that arise at the identification stage, recommendations are then given in the form of proposals for improvements to buildings and irrigation channels. The results of the field survey in the form of network tracing provide data that the level of physical and functional damage to the Sragi secondary channel infrastructure reaches >40%. The condition is categorized as very bad with the classification of severely damaged which requires repair or replacement. Most of the damage in the form of spots or localized occurred on the existing lining of masonry and precast concrete starting from Hm 50+00 to Hm75+68. The recommendations for improvement are in the form of dismantling the existing precast concrete lining according to the point of damage. It is recommended to repair the lining using K-300 precast concrete so that the structure of the irrigation channel is safe against the risk of deformation.

Characterization and Beneficiation of Fanibi Laterite for Nickel Metal Recovery Using Froth Flotation Method

This study investigates the characterization of Fanibi Laterite and the efficiency of froth flotation to beneficiate nickel from its host rock sourced in Akure, Ondo State, Nigeria. A sample of the laterite was obtained and characterized by the use of an X-ray fluorescence Spectrometer (XRFS), X-ray diffractometer (XRD), and Scanning electron microscope with Energy dispersive spectroscope (SEM/EDS). The ore was comminuted to its liberation size of -125 + 90 µm. The froth flotation process was done using Sodium hydroxide and Hydrogen tetraoxosulphate (VI) acid as hydrogen potential (pH) modifier within the range of 4,5,7,9 and 10. However, other reagents are sodium oleate as the collector, potassium dichromate as the depressant, and oleic acid as the frother. The froth and depressed obtained were dewatered and characterized using XRFS. The result revealed that the ore contained 35.65% Si, 8.24% Al, 10.87% Fe, and 0.07% Nickel. It also included some other associated minerals such as Zn, Mg, Ti, Co, and Mo in trace form of less than 1 %. XRD analysis reveals nickel as nickel iodate. The result reveals nickel assays of 0.14, 0.20, 0.15, 0.25, and 0.12%, while their recoveries are 70.82, 67.80, 86.70, 98.04, and 86.98%, respectively. The optimum nickel recovery of 98.04% was attained at a pH of nine (9). It was concluded that froth flotation could successfully beneficiate Fanibi laterite ore for nickel. At the same time, other minerals such as Titanium, Molybdenum, Tin, and Tungsten were present to be extracted for Metallurgical applications.

ВРЕМЯ ВИНТАЖНОЙ МОДЫ: ВОПРОСЫ ТЕМПОРАЛЬНОСТИ И ПАМЯТИ

The concept of “fashion” implies constant renewal and a clear rhythm of changing trends, therefore, before starting to study vintage clothing in the context of fashion, one should first prove the involvement of vintage in fashion discourse. This paper attempts to incorporate vintage into fashion discourse through the introduction of the concepts of non-linear and uchronial time. This becomes possible through the theories developed by Walter Benjamin, Michel Serres, Jean Baudrillard and other researchers. The paper consists of three parts. The first is devoted to the issues of time contained in clothing. These may be frozen forms of the past, suddenly appearing in the present due to some kind of curvature of time. Or they could be vintage objects that contain memory and time in the form of tangible or intangible traces. The second part is devoted to issues of reconstruction of the past. The image of the past is formed in the present, which is why historical reconstructions of different years differ so much. The availability of historical sources plays a big role in this.The third part is devoted to wardrobe practices of vintage lovers and the analysis of these techniques based on the above theories of nonlinear and uchronial time.

Linear Generalized n-Derivations on C∗-Algebras

Let n≥2 be a fixed integer and A be a C∗-algebra. A permuting n-linear map G:An→A is known to be symmetric generalized n-derivation if there exists a symmetric n-derivation D:An→A such that Gς1,ς2,…,ςiςi′,…,ςn=Gς1,ς2,…,ςi,…,ςnςi′+ςiD(ς1,ς2,…,ςi′,…,ςn) holds ∀ςi,ςi′∈A. In this paper, we investigate the structure of C∗-algebras involving generalized linear n-derivations. Moreover, we describe the forms of traces of linear n-derivations satisfying certain functional identity.

Forensic Microbiology: When, Where and How.

Forensic microbiology is a relatively new discipline, born in part thanks to the development of advanced methodologies for the detection, identification and characterization of microorganisms, and also in relation to the growing impact of infectious diseases of iatrogenic origin. Indeed, the increased application of medical practices, such as transplants, which require immunosuppressive treatments, and the growing demand for prosthetic installations, associated with an increasing threat of antimicrobial resistance, have led to a rise in the number of infections of iatrogenic origin, which entails important medico-legal issues. On the other hand, the possibility of detecting minimal amounts of microorganisms, even in the form of residual traces (e.g., their nucleic acids), and of obtaining gene and genomic sequences at contained costs, has made it possible to ask new questions of whether cases of death or illness might have a microbiological origin, with the possibility of also tracing the origin of the microorganisms involved and reconstructing the chain of contagion. In addition to the more obvious applications, such as those mentioned above related to the origin of iatrogenic infections, or to possible cases of infections not properly diagnosed and treated, a less obvious application of forensic microbiology concerns its use in cases of violence or violent death, where the characterization of the microorganisms can contribute to the reconstruction of the case. Finally, paleomicrobiology, e.g., the reconstruction and characterization of microorganisms in historical or even archaeological remnants, can be considered as a sister discipline of forensic microbiology. In this article, we will review these different aspects and applications of forensic microbiology.

Black body representation in Get Out (2017) and Us (2019) by Jordan Peele

Black characters soon appeared in Hollywood films such as The Birth of a Nation (1915), Intolerance (1916). They are recognised as criminals, not conceded as human rights. African-American directors created films to change the image of black people. Jordan Peele inherits the efforts of his predecessors and takes the story of black people in cinema to a new level with identity clarification. That is clearly shown in the movies Get Out (2017) and Us (2019). The research aims to identify the black body representation in the above two films by Jordan Peele as an expression of identity. Body denial is the root cause of violence among African Americans. This acts as a form of identity tracing. The research combines the use of cinematic narrative and semiotic approaches with interdisciplinary research methods such as culturology and anthropology. The basic principle of the position of the research is the theory of ethnic identity. The use of comparison, collation, analysis and synthesis will be applied in the process of developing theses.

A uniform trace theorem for Dirichlet forms on Sierpinski fractals

We establish trace theorems for the self-similar Dirichlet forms on the Sierpinski gasket and the Sierpinski carpet to their subsets generated by cutting with a straight line. For the Sierpinski gasket, the straight line can be in any direction. For the Sierpinski carpet, we require the straight line parallel to an edge of the carpet. The trace forms are expressed in term of values of functions along the cut, in a uniform way independent of the choices of the line.

Kinematic Analysis of 3-PRPPS Spatial Parallel Manipulator with Circularly Guided Base for Singularity-Free Robotic Motions

Robot manipulators are classified as serial manipulators and parallel manipulators. Parallel manipulators are classified into planar and spatial parallel manipulators (SPMs). The parallel manipulators have moved and fixed platforms connected with serial chains. The parallel manipulators have many linkages, which create a singularity problem. The singular positions of SPMs have also gained substantial attention in various industrial applications due to their intrinsic advantages in precision, flexibility, and load-bearing capabilities. The 3-PRPPS SPM has three prismatic joints, one spherical joint, and one revolute joint. This work changed the fixed base with a circular guided base to avoid singularity issues. The manipulator was modeled with direct kinematic relations. The Jacobian matrix for position and orientation was derived. The workspace was taken as the common area of the three circles, whose radius was the maximum arm length. The position and orientation of the end effector were traced. In the form of the end effector traces, no singularities in the mechanism were observed. The path of the robot manipulator was observed in all the possible positions and orientations. The multi-body simulation was also conducted on the 3-PRPPS manipulator, the main findings of which are presented in this article.

A review of trends and applications of learning analytics in higher education in the post-pandemic era

Learning analytics is defined as collecting, analysis, and reporting of data about learners inside a system. Users’ interaction, which is a form of digital traces can be processed and identified into pattern. In comparison with subjective methods such as surveys and questionnaires, learning analytics provide deeper insight on students’ behaviour and assist learning institution with data-informed decision-making regarding students’ learning issues. This paper reviews on existing literature on the latest application and the trends of learning analytics in higher education over the last few years, within the period of pre and post pandemic era. As online learning was adapted rapidly during the pandemic, learning analytics became an important tool to assess students’ learning. The literature review was obtained from Scopus and Web of Science databases by using Boolean search techniques with the right keywords. This study reviewed and provided a comprehensive analysis according to certain criteria of searched studies from the year 2018 to 2023. The result showed that the research trend in learning analytics was fluctuating in Scopus and gradually declining in Web of Science due to the pandemic and shifts in research interest. In this post pandemic era, Artificial Intelligence (AI) is trending upwards, and researchers are putting interest in integrating AI with learning analytics in education. As such, this paper could help educators see the trends of LA over the last few years, as well as the innovative practices recently.

Evaluation of the Physico-Chemical Composition and Fatty Acid Profile of Cashew Nut Oil (Anacardium Occidentale) Compared to Sunflower Oil

The cashew nut (anacardium occidentale) is rich in fat, but little exploited in Côte d'Ivoire, the world's leading producer and exporter. A better perception and consumption of cashew kernel oil could contribute to improving the population's nutrition. The aim of this study is to determine the physico-chemical quality and nutritional value of artisanal oil derived from the artisanal pressing of cashew kernels in Côte d'Ivoire. To achieve this objective, the physicochemical parameters and fatty acid profile of cashew kernel oil were determined and compared with those of sunflower oil in accordance with standard methods. On completion of the work, the fat extraction rate for roasted cashew kernels was 60.75 ± 5.6%. Physicochemical analysis of cashew nut oil yielded moisture content 0.2%, oleic acidity 0.93 ± 0.00%, acid value 17.95 ± 0.00 mg OH/g oil, peroxide value 10.1 ± 0.00 meq O2/kg, saponification 192.14 ± 0.00 mg KOH/g oil, iodine value 79.31 ± 0.00 g I2/100 g, ester value 174.19 ± 0.00. As for the fatty acid profile, the total fatty acid concentration was 94.02%. The most representative unsaturated fatty acid is oleic acid (62.19 ± 0.007), which exceeds that of sunflower oil by a factor of 4. Linoleic acid represents 16.30 ± 0.007% and linolenic acid is in trace form with 00.2 ± 0.014%. In conclusion, the analysis of the various properties studied shows that cashew nut kernel oil is a highly valued edible extra-virgin oil, which could be valorized in the food and cosmetics industries.
