Minification can help your website load several times faster
In production, it is recommended to minify any JavaScript code that is included with your application. Minification can help your website load several times faster, especially as the size of your JavaScript source code grows.
This will produce a file called like_button.min.js with the minified code in the same directory. If you’re typing this often, you can create an npm script to give this command a name.
DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market.
Under a DevOps model, development and operations teams are no longer “siloed.” Sometimes, these two teams are merged into a single team where the engineers work across the entire application lifecycle, from development and test to deployment to operations, and develop a range of skills not limited to a single function.
In some DevOps models, quality assurance and security teams may also become more tightly integrated with development and operations and throughout the application lifecycle. When security is the focus of everyone on a DevOps team, this is sometimes referred to as DevSecOps.
These teams use practices to automate processes that historically have been manual and slow. They use a technology stack and tooling which help them operate and evolve applications quickly and reliably. These tools also help engineers independently accomplish tasks (for example, deploying code or provisioning infrastructure) that normally would have required help from other teams, and this further increases a team’s velocity.
Move at high velocity so you can innovate for customers faster, adapt to changing markets better, and grow more efficient at driving business results. The DevOps model enables your developers and operations teams to achieve these results. For example, microservices and continuous delivery let teams take ownership of services and then release updates to them quicker.
Increase the frequency and pace of releases so you can innovate and improve your product faster. The quicker you can release new features and fix bugs, the faster you can respond to your customers’ needs and build competitive advantage. Continuous integration and continuous delivery are practices that automate the software release process, from build to deploy.
Ensure the quality of application updates and infrastructure changes so you can reliably deliver at a more rapid pace while maintaining a positive experience for end users. Use practices like continuous integration and continuous delivery to test that each change is functional and safe. Monitoring and logging practices help you stay informed of performance in real-time.
Operate and manage your infrastructure and development processes at scale. Automation and consistency help you manage complex or changing systems efficiently and with reduced risk. For example, infrastructure as code helps you manage your development, testing, and production environments in a repeatable and more efficient manner.
Build more effective teams under a DevOps cultural model, which emphasizes values such as ownership and accountability. Developers and operations teams collaborate closely, share many responsibilities, and combine their workflows. This reduces inefficiencies and saves time (e.g. reduced handover periods between developers and operations, writing code that takes into account the environment in which it is run).
Move quickly while retaining control and preserving compliance. You can adopt a DevOps model without sacrificing security by using automated compliance policies, fine-grained controls, and configuration management techniques. For example, using infrastructure as code and policy as code, you can define and then track compliance at scale.
Software and the Internet have transformed the world and its industries, from shopping to entertainment to banking. Software no longer merely supports a business; rather it becomes an integral component of every part of a business. Companies interact with their customers through software delivered as online services or applications and on all sorts of devices. They also use software to increase operational efficiencies by transforming every part of the value chain, such as logistics, communications, and operations. In a similar way that physical goods companies transformed how they design, build, and deliver products using industrial automation throughout the 20th century, companies in today’s world must transform how they build and deliver software.
Transitioning to DevOps requires a change in culture and mindset. At its simplest, DevOps is about removing the barriers between two traditionally siloed teams, development and operations. In some organizations, there may not even be separate development and operations teams; engineers may do both. With DevOps, the two teams work together to optimize both the productivity of developers and the reliability of operations. They strive to communicate frequently, increase efficiencies, and improve the quality of services they provide to customers. They take full ownership for their services, often beyond where their stated roles or titles have traditionally been scoped by thinking about the end customer’s needs and how they can contribute to solving those needs. Quality assurance and security teams may also become tightly integrated with these teams. Organizations using a DevOps model, regardless of their organizational structure, have teams that view the entire development and infrastructure lifecycle as part of their responsibilities.
There are a few key practices that help organizations innovate faster through automating and streamlining the software development and infrastructure management processes. Most of these practices are accomplished with proper tooling.
One fundamental practice is to perform very frequent but small updates. This is how organizations innovate faster for their customers. These updates are usually more incremental in nature than the occasional updates performed under traditional release practices. Frequent but small updates make each deployment less risky. They help teams address bugs faster because teams can identify the last deployment that caused the error. Although the cadence and size of updates will vary, organizations using a DevOps model deploy updates much more often than organizations using traditional software development practices.
Organizations might also use a microservices architecture to make their applications more flexible and enable quicker innovation. The microservices architecture decouples large, complex systems into simple, independent projects. Applications are broken into many individual components (services) with each service scoped to a single purpose or function and operated independently of its peer services and the application as a whole. This architecture reduces the coordination overhead of updating applications, and when each service is paired with small, agile teams who take ownership of each service, organizations can move more quickly.
However, the combination of microservices and increased release frequency leads to significantly more deployments which can present operational challenges. Thus, DevOps practices like continuous integration and continuous delivery solve these issues and let organizations deliver rapidly in a safe and reliable manner. Infrastructure automation practices, like infrastructure as code and configuration management, help to keep computing resources elastic and responsive to frequent changes. In addition, the use of monitoring and logging helps engineers track the performance of applications and infrastructure so they can react quickly to problems.
Together, these practices help organizations deliver faster, more reliable updates to their customers. Here is an overview of important DevOps practices.
Yes you can delete everything inside of /var/log/journal/* but do not delete the directory itself. You can also query journalctl to find out how much disk space it’s consuming:
$ journalctl --disk-usage
Journals take up 3.8G on disk.
You can control the size of this directory using this parameter in your /etc/systemd/journald.conf:
NOTE: You might need to restart the logging service to force a log rotation, if the above signaling method does not do it. You can restart the service like so:
$ sudo systemctl restart systemd-journald.service
abrt logs
These files too under /var/cache/abrt-di/* can be deleted as well. The size of the log files here is controlled under:
$ grep -i size /etc/abrt/abrt.conf
# Max size for crash storage [MiB] or 0 for unlimited
MaxCrashReportsSize = 1000
You can control the max size of /var/cache/abrt-di by changing the following in file, /etc/abrt/plugins/CCpp.conf:
DebugInfoCacheMB = 2000
NOTE: If not defined DebugInfoCacheMB defaults to 4000 (4GB).
Many modern file systems employ a journal including NTFS, Ext3/4, XFS, HFS+, and others. The journal helps with two things, avoiding file system corruption and speeding up recovery after a failure such as a power loss or system crash. There are two major components to a file system, the data and the metadata. The data is the contents of a file, image, video, documents, and ultimately it is what gives the file system it’s value. The metadata is what describes the structure of the filesystem including how files are named, stored in directories, access permissions, file modification times, and recording areas of the disk that are in use or are free to be allocated to other files as they grow or are created. If the metadata becomes corrupted because of a system crash, it could lead to further data loss/corruption. For example, part of the disk might be selected for allocation to a file, but if it’s not recorded correctly before a crash, it might be added to the file’s list of data blocks, but still in the list of free data blocks and allocated to a second file later on. Now, there are two files that are sharing the same data blocks/content.
The journal is a place on the disk reserved for recording changes to the file system. The exact details of what is being changed it written first to the journal located in a single location on disk, then, after the journal is updated, the changes are applied to the appropriate locations on the disk which might require several writes. One the updates are done, the journal entry is marked as complete. After a crash, the system only need to examine the journal for incomplete entries and complete them to fix the file system. This speeds recovery and ensures a change is made entirely or not at all. If a block is allocated to a growing file, it will be added to the file’s block list and also marked as in use.
Also, on file systems that support journalling, most often it’s only metadata journalling to preserve the structure, but not the data itself. Full data journalling is normally quite expensive and slow, but less crucial than metadata. It’s possible to enable for data as well if needed.
Also, to complete this, there are some file systems that don’t currently offer journalling including FAT32, exFAT, Ext2, and UDF. If there’s a crash during an update, a full scan of the filesystem needs to be done to track down any errors or corruption.
It is run-queue i.e a queue of processes waiting for a resource(cpu, i/o etc.) to become available .
Consider a single-core cpu as a single lane of traffic with bridge and process as cars.
Now in this situation System load is
0.0 – If there is no traffic on the road.
1.0 -If the traffic on the road is exactly the capacity of bridge.
More than 1 – If the traffic on road is higher than the capacity of bridge and cars have to wait to pass trough the bridge.
This number is not normalized according to your cpu. In Multiprocessor system, load 2 mean 100 % utilization of we are using dual-core processor, load 4 means 100% utilization if we are using quad-core.
