The main goal is to show the kids a few about science and technology, in order to rise the interest on these fields through practical activities that are carried out during the event. Another
important goal is to spread the opportunities for studying at Federal Institute of Education,
Science and Technology of Paraíba, as well a campus tour, where the event is held.
The first edition was held on October 29, 2016, with the participation of 34 students from the State Middle and High School Professor Maria Helena Bronzeado Machado. Fifty-five IFPB students enrolled to volunteer at the event, from the most diverse majors: Electrical Engineering, Interior Design, Computer Networks, Systems for Internet and Electronics Technical course.
After TechKids, several participants enrolled in the ission process for technical courses at IFPB and two of them were approved for Electronics Technical Course, at 1st and 3rd general place. Among the offered activities, the most important were Programming Workshops (Scratch and AppInventor), Robotics (Lego Mindstorm) and the Chemistry Show. -

Performance Evaluation of Snapshot Methods to Warm the Serverless Cold Start
arXiv
The serverless computing model strengthens the cloud computing tendency to abstract resource management. Serverless platforms are responsible for deploying and scaling the developer's applications. Serverless also incorporated the pay-as-you-go billing model, which only considers the time spent processing client requests. Such a decision created a natural incentive for improving the platform's efficient resource usage. This search for efficiency can lead to the cold start problem, which…
The serverless computing model strengthens the cloud computing tendency to abstract resource management. Serverless platforms are responsible for deploying and scaling the developer's applications. Serverless also incorporated the pay-as-you-go billing model, which only considers the time spent processing client requests. Such a decision created a natural incentive for improving the platform's efficient resource usage. This search for efficiency can lead to the cold start problem, which represents a delay to execute serverless applications. Among the solutions proposed to deal with the cold start, those based on the snapshot method stand out. Despite the rich exploration of the technique, there is a lack of research that evaluates the solution's trade-offs. In this direction, this work compares two solutions to mitigate the cold start: Prebaking and SEUSS. We analyzed the solution's performance with functions of different levels of complexity: NoOp, a function that renders Markdown to HTML, and a function that loads 41 MB of dependencies. Preliminary results indicated that Prebaking showed a 33% and 25% superior performance to startup the NoOp and Markdown functions, respectively. Further analysis also revealed that Prebaking's warmup mechanism reduced the Markdown first request processing time by 69%.

Prebaking Functions to Warm the Serverless Cold Start
Middleware '20: Proceedings of the 21st International Middleware Conference
Function-as-service platforms promise a simpler programming model for cloud computing, in which the developers concentrate on writing its applications. In contrast, the platform takes care of resource management. As FaaS s are billed based on the execution of the functions, platform providers have a natural incentive not to keep idle resources running at the platform's expense. However, this strategy may lead to the cold start issue, in which the execution of a function is delayed because…
Function-as-service platforms promise a simpler programming model for cloud computing, in which the developers concentrate on writing its applications. In contrast, the platform takes care of resource management. As FaaS s are billed based on the execution of the functions, platform providers have a natural incentive not to keep idle resources running at the platform's expense. However, this strategy may lead to the cold start issue, in which the execution of a function is delayed because there is no ready resource to host the execution. Cold starts can take hundreds of milliseconds to seconds and have been a prohibitive and painful disadvantage for some applications. This work describes and evaluates a technique to start functions, which restores snapshots from previously executed function processes. We developed a prototype of this technique based on the CRIU process checkpoint/restore Linux tool. We evaluate this prototype by running experiments that compare its start-up time against the standard Unix process creation/start-up procedure. We analyze the following three functions: i) a "do-nothing" function, ii) an Image Resizer function, and iii) a function that renders Markdown files. The results attained indicate that the technique can improve the start-up time of function replicas by 40% (in the worst case of a "do-nothing" function) and up to 71% for the Image Resizer one. Further analysis indicates that the runtime initialization is a key factor, and we confirmed it by performing a sensitivity analysis based on synthetically generated functions of different code sizes. These experiments demonstrate that it is critical to decide when to create a snapshot of a function. When one creates the snapshots of warm functions, the speed-up achieved by the prebaking technique is even higher: the speed-up increases from 127.45% to 403.96%, for a small, synthetic function; and for a bigger, synthetic function, this ratio increases from 121.07% to 1932.49%.

Second place at Vsoft Contest 2017
Vsoft Company
In the first year of my Bachelor’s degree in Computer Science, I participated in the Vsoft Contest 2017 for the development of a fingerprint recognition algorithm. Vsoft is a brazilian company that develops solutions for biometric personal identification.
The contest main goal is develop a solution to fingerprint recognition with the lowest Equal Error Rate (EER).
My solution as ‘RUSSIAN WEAPON 2’ has got the second place with an 8.89% EER.
