How to check the file checksum on MacOS


The internet has brought many facilities in our life, but a general use increasingly born without a negative. As the spread of the Internet continues to be done as before, security issues are also increasing. It has become so easy for hackers to insert downloaded viruses into a file. In addition, the files may be corrupted or changed during download. In that case, how do you guarantee the integrity of the downloaded file? The answer is in the checksum.

Checksum is a code that consists of a series of characters provided by the site to ensure the integrity of the files downloaded from the site. To do this, download the file, run a local checksum on your computer, and compare it with the checksum specified on the site. Both values ​​are based on the fact that if the letters and letters match, the downloaded file was not modified in the download process, it is exactly the same as the intended font. On the other hand, if both checks do not match, it can be concluded that file integrity is corrupted, corrupted, or likely to be defective during download.

Some sites offer their own services to test the checksum of the file after download, and if you do not provide this tool? For Apple Mac users, here is their answer:

Terminal application for MAC users
The terminal application already exists on your Mac computer and can be used to check the local checksum of the downloaded file so that the online checksum generator or application help is not required. Just perform the following steps and generate a checksum for the purpose of comparison.

First, download the target file from the site to the Mac. For example, I downloaded a free WinMD 5 tool to check a checksum and a Mac terminal. They had a checksum available on my site that I could compare my sum of locally generated check.

Click the Launchpad on the Mac’s dock and select Terminal. Then the Terminal opens.
First, when you start, type the command ‘md 5’ in the terminal, press the spacebar and enter the path of the last downloaded file. If you’re worried, just type the full path or simply drag and drop the file into a terminal window to see the full path of the file right away. You can then start by pressing the Enter key on the terminal.

The terminal will immediately generate a checksum of the target file and display it so you can observe it. This is usually a series of letters and digits at the end.

Compare this locally generated checksum with the checksum on the file site and note the difference.

If there are no differences between the two strings of text, you are good. However, if both are different from each other, this means that the file has been corrupted or changed.

With Terminal on Mac, you can easily understand the integrity of the downloaded file in minutes. You no longer have to worry about the modified files that are on your system.


Bulutta Supercharged web hosting

If your site suffers from many users, or if you just want to get good performance in the future, you probably think you want to update your web hosting page. While “advanced users” tend to see projects against standard hosting standards, the cloud offers the new ideal home.
What is an advanced user?

The term “advanced user” is used in various technology industries. It refers to someone using the most advanced source of a product or service. Advanced users determine higher requirements than average consumers, but at the same time they do not have a high level of technical experience.

In the context of a web hosting, there are advanced users, traffic-intensive sites, and other intensive applications such as e-commerce. If you are an advanced hosting user, you can use your site in high traffic on a shared hosting platform.

Perhaps this hosting solution meets your needs at first, but when the company grows and demands it, the shared bandwidth and processing power can not easily accompany it.
Hosting sharing limits

With the restriction of multiple users on the same server, shared hosting can cause significant restrictions. Even in high end packages, a shared platform will always fight to handle larger volumes of traffic.

More visitors mean more people not only looking at your site, but more concurrent requests, more data flying back and forth, and more servers.

When shared hosting comes to you, you can expect slow load times, frustrated customers and lost sales, especially in e-commerce transactions. This does not mean the potential damage to your organization.

Needless to say, a big problem for any online business – what are you doing?
Dedicated hosting is updated dedicated

The obvious solution is updating a dedicated server. However, as noted, an advanced user is not necessarily an expert in hosting because it sets high standards. Configuring, maintaining, and maintaining a server can be complex and time-consuming and requires some special skills.

Even if you are an experienced developer who knows the coding language of your choice in detail, you may not have the time or experience to manage your own server.

If you want the performance of your own server resources, but you do not want to do it yourself, what are your options? Of course you can hire a server administrator to do it for you, but a more infectious and flexible solution is managed as a cloud hosting platform.
Cloud hosting for advanced users

In a next-generation cloud hosting platform like CloudNX, resources are entirely reserved for you, and your projects are completely isolated from other client’s activities. In this way, it is exactly the same as its own dedicated server – with virtualized resources instead of just a physical box.

But unlike a traditional server, our platform offers a managed choice. This provides a special environment for the language or scripting application you choose while removing the complexity of the server and operator.

Simply choose the stacking components (scripts, webserver and database) and Fasthosts provide you with the knowledge and skills to keep the environment safe and up-to-date, leaving you more time at the end of your projects.

Less friction, less load and server maintenance is not required – all of which comes with simplified projects and potentially shortened market time.
Options for losing or retaining a collision

But do you have the disadvantage of ignoring the server administrator? Managed cloud hosting provides a solution for users who do not want or need root access to change every file on the server and load applications across the entire server. For highly customized configurations, root access is generally preferred, but often not required. Cloud hosting management still offers all the tools users need to run a wide range of applications; it is not necessary to access the roots.

And then if you need servers with root access, coverage is off. CloudNX provides a central interface for all your virtualized services; you can return virtual machines with options for Windows and Linux operating systems, along with stacks and applications managed from a single intuitive control panel.
More performance, more flexibility

Another question for advanced users is flexibility. Quality accommodation should provide dynamically scalable resources according to the current student. It is not possible for a hosting package to be shared on a dedicated physical server without the time to update or the hardware must be manually changed.

Advanced users also require space to grow. Projects start small, but with anticipation of future expansion. Again, you do not want to be locked down on a hosting plan or physical server that will not wait for a few months.

With next-generation cloud services, you have the option to increase or decrease server resources on demand. So if you need to add RAM and additional processors to make a temporary increase in web traffic, or if you need to make new software drivers part of a long-term plan, everything is possible on a single virtualized platform.

What is Mobile Cloud and how does it work?

Today, there are already mobility platforms that, based on a distributed computing process, serve the most diverse business areas
In today’s cloud computing model, state-of-the-art servers and data centers are available to meet the most diverse market demands, thus ensuring the best availability and scalability of solutions. Actually, that’s what happens on the SERVER side. But on the CLIENT side, we have mobile applications that drag data through a very limited communication channel – the Internet.

When talking about Internet access through mobile telephony, we speak, at best, of LTE and 4G, which guarantee fast access to the Internet. But can we have that access in every corner of the country? In the capitals of Sao Paulo, Rio de Janeiro, Brasilia and others, how many times do we not find a very high response time to download an e-mail or a message, this is a reality and, in the coming years, we will have improvements , but still be limited.

In this way, we ask ourselves: why request resources from the cloud through a limited channel if we have smartphones and tablets with the latest technology capable of storing and processing Gigabytes of information locally?
Today, there are already mobility platforms that, based on a distributed computing process, serve the most diverse business areas (sales, commercial marketing and field services), causing only relevant information to the requesting user to be trafficked. In this way, operations and complex scenarios can be supported with maximum performance through the concept we call Mobile Cloud.

How does the Cloud Cloud work?

– In the first access, the user downloads all the information relevant to the mobile device. Example: customer portfolio, visit script, customer data, credit limit, products, inventory, prices and payment conditions relevant to this portfolio.

– All information is stored and available on the mobile device, there is no need for Internet connectivity, and also provides quick access to information.

– Only the data that changed the device or the server is trafficked, either through data synchronization or sending, where the server notifies the cell that there is information available to be trafficked (differential method).
With the Mobile Cloud concept, several business processes are provided, such as:

– Sales processes:

– Traditional pre-sale channel

– Modern pre-sales channel

– OrderTacking

– Van-sales

– Commercial marketing

– Field Service Processes:

– Management of Field Technicians

– Engineering Project Management – GIS Mobile (Utilities)

– Audit of stores (retail sale)

– Maintenance and Asset Management. (Retail and banks)

Nowadays, many solutions are already available for companies, the important thing is to find and find what best suits your needs. In the case of companies that need to speed up their commercial representatives, but can not count on the effectiveness of the Internet, we can use that alternative.

What cloud computing means: less cost, more result

What is cloud computing? Well, in the letter, cloud, in English, means cloud. And computing, it was easy: computing.

Putting everything together, we have: cloud or cloud computing, if you prefer. Ok, but what does cloud computing really mean? Why cloud? Does your data and information float without control?
No, not even! Cloud computing is much safer for your data, in fact, especially if you are a small or medium-sized company looking for cost reduction and outsourcing of tasks that are not your core business.

But before talking about the great advantages of cloud computing being used correctly in your company, will we better understand how this company works?
Imagine a small company with about 10 employees. Let’s say it is an accounting office that has its own payroll management software, invoice issuance, tax calculations, many documents, applications, passwords, licenses, digitized and archived contracts, licenses, addresses, clients, etc.

All this may have been developed by them, be on worksheets distributed by the company’s computers or even be software “off the shelf”, that this company bought several licenses and installed on all its machines and on one server.
Now imagine the cost of all this:
Develop systems (or buy ready) and install on all machines.
Keep all this and install (or develop) updates continuously.
And more: keep the servers active and always be careful if they are with an error or access error.

Server maintenance and concern about power failure, for example.
It’s not over: manual backup, file to another server or other medium, sort it into folders and know where to find it.

And, finally, the most difficult of all: to guarantee the security of this confidential information of the companies of the clients: to install firewalls, to supervise attempts of intrusion, losses of physical files, like diskettes and pen drives, etc.

In short: a lot of money spent, people, hours of teamwork and diverting the attention of employees to what matters most: efficiently accounting for their customers to satisfy them, keep them loyal and continue to generate profits.

And if you can change everything for an affordable and more efficient solution and still offer much more teamwork, collaboration and results?
It is what cloud computing means!
But how does all this work?
Companies the size of Microsoft and Google created huge and secure facilities, equipped with the most modern servers in the world and distributed in the four corners of the earth.

With all the professionalism and experience of these companies, you can save files and access applications there, even hundreds of kilometers from your company, and have all the convenience you already have when using a computer, dragging and dropping icons, using simple searches and edit your documents normally.

And with the advantage of being much cheaper, secure and accessible from anywhere and by the most diverse devices, as if they were floating in a cloud. But they are not. They are very well guarded by these business information technology icons!
Here is a summary of what cloud computing means in terms of benefits for your business!
Collaboration and teamwork: access and editing of files in a shared manner, levels of access defined according to the responsibility of each employee.

Mobility and agility: view information and applications (CRM, actions, financial or any other available in the cloud – SaaS) wherever you are and have access to up-to-date, reliable and real-time information.

Ease of remote work and in transit: your employee is visiting a client in another country? You have access to everything in the company without problems. Have you had a setback at home and need to work from there for a few days? Everything is alright!
Information security: we already talked about how big companies guarantee for you.

Scalability: As cloud-based software is usually offered in the form of monthly signatures, it is very easy to register or remove users quickly, paying only for actual use.

Freemium options: you can try an application before buying the signatures (in a “free” version – free – of Premium level, but with some restrictions of use) or even use this free solution definitely, depending on the case.

Without backups and maintenance: we already talked about this, as well as constant updates.

Now, is it clear to you what cloud computing means? Do you see how there is no mystery behind that concept?

Cloud consultant in cloud computing services: how does it work?


The cloud is already a reality for many companies, even those of small and medium size. Day after day, more entrepreneurs migrate their businesses, databases and operations for cloud computing services.

Although the advantages and ease of use of this technology are many, its implementation and maintenance are not necessarily simple enough for anyone to take care of it.

Many companies pay fortunes in cloud services that offer full support and hire additional IT professionals or even outsourced teams to handle this innovation. Part of the objectives of a cloud migration are lost, with the remaining high costs and an even higher level of managerial complexity.

For this reason, some of the biggest players in the world in the IT services of the company.


The services provided by the so-called “cloud log” are a model that provides the best solution advice, support and manages all the infrastructure and technical aspects of a cloud-based system.

The delivery of services in this mode also begins to plan the migration and adoption of a cloud infrastructure, change management, and continues indefinitely, solving problems, supporting the company in the use of platforms and making changes whenever necessary. Wide and varied experience is an indispensable necessity in the case of advice in cloud computing – there is generally no room for failures in systems of that nature, and improvisation and amateur are risks that a company can not execute.

Of course, anyone can hire an online cloud computing service – however, configure, manipulate and do it completely for your company is more than five hundred.

The cloud consulting contracts, in addition to helping in the search for the best solution for your company, in the implementation and migration, has several other advantages.

Advantages of the cloud consultant in contracting services in the computig cloud:

Accelerate the migration process from servers and physical systems to virtual systems in the cloud.

Improve processes and operations, optimizing and monitoring local hardware and software and the cloud platform.

Reduce operational and partial costs resulting from the local management of cloud computing platforms.

Eliminate common problems when deploying a cloud architecture.

Planning and reports

Technical problems, complex IT routines and support phone calls are turned into practical reports and action plans in the cloud consultant model. The client company migrates its systems to the cloud and makes use of the new platforms, but does not directly support the burden of maintaining and configuring those systems – which offers a return on agility and costs and an optimal way to improve work productivity.

The programming architects that provide this type of service, for the most part, have certifications in the systems to be implemented, such as Google Cloud, Microsoft, Salesforce and others. More focused and experienced in the cloud computing architecture than internal IT professionals, these “advisors” perform a series of tasks within the scope of the cloud counselor, including:

Scope of the advisory tasks of a cloud computing service:

Implementation and development of projects.

Creation of prototypes and systems for tests.

Governance in IT

Reports and platform diagnostics.

Innovations in operations and approaches.

Strategic plans in cloud computing.

Rationalization of resources.

Systems architecture.

Suggestion of new software, systems and frameworks.

With all the expert-driven management, your company can focus on key KPI analysis related to the use of IT and the cloud, as well as ROI cost reporting. Thus, with more time for the main business of your company, the management of teams and the management of activities become much more agile.


How does the Cloud Advisor work?

The cloud consultant is not just a migration to cloud computing services.

It works in different stages, starting with the identification of needs so that there is an improved migration to the online systems in the cloud.

From the surveys, a plan is designed so that the correct options are transferred in terms of cloud computing services.

The implementation, when conducted with a cloud consulting service, depends on continuous support, mitigating the impacts that may occur during the migration and providing the necessary contingencies for the customer’s operations to get used to the new routine.

After the implementation, unlike other migration options, the support does not end. Continuous consulting continues to identify new solutions and modifications that can make cloud computing systems more convenient, optimized and customized for the client’s processes.

The cloud consultant operates under continuous process improvement values, with uninterrupted monitoring of the efficiency of the platform and actions taken in case of loss of quality or performance.


In summary, it is possible to say that the cloud consultant model makes the migration to cloud and cloud computing services just another corporate decision, to be operated by professionals specialized in platforms with constant information flows.

What defines a good cloud counselor?

As the term itself may seem new, even before you can adhere to this new trend, you need to know what is important: what makes a cloud consultant a competent provider?

First, the vast majority of cloud-related technologies, such as Google, Microsoft, Oracle, and so on, have specific certifications that demonstrate quality and level of service.

A good provider of cloud computing services has technicians with training and certification in various platforms and is licensed and certified to operate with these systems, a type of endorsement by developers, which shows that the company is able to operate and service customers with the standards and methods required and charged by the company responsible for the development of these technologies.

Another interesting way to mark your hiring, as happens in other segments, is the existence of good service cases.

A cloud counselor is a provider capable of generating large structural changes in the IT area of ​​any business. Such cases, to identify a better level of service, should include data and information on productivity gains and cost savings – perhaps the two factors that most “push” new customers to the cloud today.


Specialists in various IT areas and even other support segments, cloud computing, seals and cloud certifications, successful and memorable, consistent with the cloud technology sector – everything that defines a full service cloud advisor and really useful for your company.

More than an “outsourced IT team”, the key aspect of a good cloud advisory service is intelligence – creating new processes, conducting consistent analysis and experiments, and always looking for results.

An example of successful implementation of cloud computing services occurred with the Julietto Group, where internal communication and between teams did not share and distribute agile information, mainly with the matrix. From this point of view, it has been suggested to use G Suite (formerly Google Apps for Work), which allows centralizing easily editable and shared documents, integrating the various units and the matrix in an agile way.
