O início dos anos 2000 assistiu às aclamações públicas extravagantes em favor do software livre na América Latina. Em setembro de 2004, o então presidente da Venezuela, Hugo Chávez, reafirmou sua postura de esquerda ao prometer adotar o uso de software livre nas instituições governamentais. Uma declaração similar foi feita pelo congresso peruano no começo dos anos 2000, que resistiu à forte oposição da Microsoft. O Brasil também se posicionou cedo neste cenário, quando o PT, liderado pelo Presidente Luiz Inácio “Lula” da Silva, assumiu o desafio em prol do software livre depois de tomar posse em 2003. Para receber o apoio do governo brasileiro, programadores de software livre trabalharam junto de afiliados do partido e com empresas de computação com ampla operação no Brasil, tais como a Sun Microsystems, a IBM e a Red Hat.

Open Source no Brasil Ebook free download pdf pdf

O Brasil, que não faz muito tempo era um dos destaques da economia mundial (lembram-se da promessa do grupo BRICS, formado por Brasil, Rússia, Índia, China e África do Sul?), foi recentemente abalado por sua conjuntura política, localização geográfica e história. Quando se acrescenta o desalento de ver um grupo de políticos sendo acusado de corrupção (por outro grupo que, por sua vez, também é acusado de corrupção); a queda no preço das commodities; a crise da gigante estatal petrolífera (Petrobras); as pressões de sediar os Jogos Olímpicos (e os frequentes protestos decorrentes disso); a ameaça do zika vírus; os problemas com a saúde pública; e a ameaça de criminalidade enfrentada com incursões policiais hostis, pergunta-se como o Brasil consegue seguir adiante.

HDFS is not the only, and in fact, not the earliest or the latest distributed file system. CEPH claims to be more flexible and to remove the limit on the number of files. HDFS stores all of its file information in the memory of the server which is called the NameNode. This is its strong point - speed - but it is also its Achilles' heel! CEPH, on the other hand, makes the function of the NameNode completely distributed. Another possible contender is ZFS, an open-source file system from SUN, and currently Oracle. Intended as a complete redesign of file system thinking, ZFS holds a strong promise of unlimited size, robustness, encryption, and many other desirable qualities built into the low-level file system. After all, HDFS and its role model GFS both build on a conventional file system, creating their improvement on top of it, and the premise of ZFS is that the underlying file system should be redesigned to address the core issues. I have seen production architectures built on ZFS, where the data storage requirements were very clear and well-defined and where storing data from multiple field sensors was considered better done with ZFS. The pros for ZFS in this case were: built-in replication, low overhead, and - given the right structure of records when written - built-in indexing for searching. Obviously, this was a very specific, though very fitting solution.

I cannot count the number of times I have encountered CSS scoping issues through‐ out my career. Some of them were due to broad selectors such as div , the overusage of !important , or improperly namespaced CSS. Other times it has been difficult to override widget CSS or widget CSS has bled out, impacting application-level CSS. As an application grows in size, especially if multiple developers are working on the code base, it becomes even more difficult to prevent these problems. Good standards can help to mitigate these issues, but most applications leverage open source libraries such as jQuery UI, Kendo UI, Bootstrap, and others, which makes good standards alone inadequate. Addressing these problems and providing a standard way of apply‐ ing styles to scoped elements are two of the benefits of using a shadow DOM.

Troubleshooting OpenVPN  Ebook free download pdf  pdf

Troubleshooting OpenVPN Ebook free download pdf pdf

In the case of OpenVPN, a user certificate may be added to the local CRL because the employee left the company, or perhaps a given OpenVPN server has been decommissioned so that server certificate is no longer required. It is best practice to deploy the CRL with OpenVPN on the server side. Technically speaking, it is possible to deploy the CRL on the client side, as well, but the utility is limited and the logistics of pushing an updated CRL to clients is difficult. There is talk of OpenVPN 3.0 adding support for CRL Distribution Points (CDPs) that would allow the client to query a special URL, LDAP, or other source to pull on-the-fly CRL data.

R and Python are likely popular because they are easily accessible and effective open source tools for analysis. More traditional statistical programs such as SAS and SPSS were far less common than R and Python.

In April of 2015, Microsoft announced Service Fabric for their Azure cloud offering. This new service lets you build microservices using containers and is apparently the same technology that has been powering their underlying cloud offerings for the past five years. Mark Russinovich (Azure’s CTO) gave a helpful overview session of the new service at their annual //Build conference. He was pretty clear that the underlying technology in the new service was not Kubernetes—though Microsoft has contributed knowledge to the project GitHub site on how to configure Kubernetes on Azure VMs. As far as I know, the only fully managed Kubernetes service on the market among the large public cloud providers is Google Container Engine (GKE). So if your goal is to use the things I’ve discussed in this paper to build a web-scale service, then GKE is pretty much your only fully managed offering. Additionally, since Kubernetes is an open source project with full source code living on GitHub, you can really dig into the mechanics of how GKE operates by studying the code directly.

Presently, there are many within the ChatOps community who are discussing and engineering ways to address security concerns. Although many of the existing and widely used chatbots available are open source, contributors to those projects are beginning to add components that allow for interaction with authorization services or internally hosted Lightweight Directory Access Protocol (LDAP) or Active Directory (AD) servers. By establishing user-, group-, and role-based rules regarding who can execute commands, many of the existing security concerns of organizations can be addressed. As mentioned previously, all commands are automatically captured in real time from within the chat client, including details of who executed the commands and timestamps. Additionally, a few chatbots and ChatOps frameworks currently under development (such as Cog) are providing access control functionality and logging for audit and reporting purposes. This further addresses the compliance control and safety concerns that prohibit many organizations from exploring the opportunities and benefits that ChatOps may provide them.

We’ve looked at several case studies of open source, open governance, and the foundation model and seen the value and future of true openness as the path to collaboration with innovation and co-opetition for cloud technologies. We’ve also noted that among major cloud initiatives and projects, there is a growing sense that cross-collaboration with other major projects is the way forward to solve the cloud computing challenges looming on the horizon. We can also see that the lines are blurring between operator, developer, producer, and consumer, and that the nature of the code, community, and culture of open source is shifting, transcending traditionally designated roles. This is leading to an era where truly anyone can be an open source developer and contribute to projects that interest them, whether by shoring up

Fast-forwarding to the modern era, the introduction of the GNU project and accompanying free software ideas from Richard Stallman in the 1980s, quickly followed by Linus Torvalds and the Linux operating system in 1991, were milestones that, combined with the increasing ease of network connectivity around the globe and mass communication via access to email, early primitive websites, and code repositories on FTP servers, led to a huge influx of new participants in the open source movement. Linux and various GNU project components provided a free base layer for open source activities. All the tools necessary for participating in open source—compilers, editors, network clients, and additional scripting languages and utilities—were embedded in a single freely accessible operating system environment, thereby significantly lowering the bar for entry and involvement by any party with access to a basic personal computer.

Prior to using clip art from a vendor or website, you should ascertain what kind of licenses are available for the graphic. Early in the history of SVG, most graphics were released under some kind of Creative Commons license, but increasingly, high-quality artwork is produced by professional artists working within traditional copyright domains. Although there are plenty of free-to-use graphics available (some with noncommercial restrictions or attribution requirements), others are offered under paid license systems similar to those used for stock photos or web fonts.

Unless you are working or have worked at this scale, you haven’t run into the issues and scenarios that come up when running a web application nationally or globally. To compound the issue, no one was talking about these specific issues; or if they were, they were focusing on different aspects of the problem. Things like scaling at the backend, resiliency, and virtual machine (VM) tuning are all important topics and get the lion’s share of the coverage. Very few people are actually talking about utilizing cache tiers to scale at the frontend. It was just a learned skill for those of us that had been living and breathing it, which meant it was hard to find that skill in the general population.

Implementing SSH  Ebook free download pdf  pdf

Implementing SSH Ebook free download pdf pdf

Most security professionals probably discovered SSH very early in their careers and have fallen in love with it ever since. SSH to the security profes- sional is like a donut to Homer Simpson: a godsend. Professionals continually ask themselves if there is anything SSH can’t do. For the security professional, SSH provides everything one could ask for, including a free car wash on week- ends (well, that is what it seems like sometimes). One of the great things about SSH is that not only do security professionals use and love the utility, but non- security technical professionals and nontechnical professionals love it as well. Furthermore, SSH is compared with other security utilities in the industry, such as RSA SecureID tokens, it is evident that security professionals are the predominant end-users of these other utilities. SecureID tokens are not widely used by nontechnical personnel and are not deployed often in environments that are not closely affiliated with corporate security. On the other hand, SSH is deployed in many Unix workstations/servers, Windows workstations, and a variety of network devices such as Cisco routers and switches.

workflow, the step, and the microinteraction before you can get to the crux of the problem. The overhead can discourage feedback, and the longer you go between check-ins, the more you have to explain, and the greater risk the team will have gotten something wrong. By having the pair in the room looking at the same problem at the same time, the information overhead is dropped to zero and the course-correction is continuous, which enables free- flowing, constant, and confident iteration. Meetings with other stakeholders can of course require backing up to earlier design choices, but that the design pair will have lots of practice vocalizing rationale, so this becomes less

A utility class is a class that contains grouped functionality but no persistent data mem- bers (attributes). Although utility classes are not part of standard C++, some program- mers like to create them; the UML therefore offers support for them. The purpose of a utility class is to take a set of functionality (such as trigonometric math functions) and group them together in a common class. There is no need to create an instance of this class because each function in the class is declared static : You simply use the functions contained in the class by fully qualifying the desired function name. For example, the trigonometric class may contain the Cosine() , Sine() , and Tangent() functions that can be called at any time by any class. The class diagram notation supports utility classes by prefacing the class name with <<Utility>> . The class diagram for the
