Backed by the Blockchain

One of SignHash’s biggest strengths is its simplicity and privacy-first approach. Because only a hash of the document is recorded, the original file never needs to be uploaded or retained, which is appealing for sensitive or proprietary materials. This makes it especially useful for creators, developers, and professionals who want proof of authorship, version history, or chain of custody without relying on centralized storage. Any future change to the document would immediately break the hash match, making tampering easy to detect.

That said, SignHash isn’t meant to replace legal notarization or full electronic signature platforms. It doesn’t verify signer identity or capture intent in the way tools like DocuSign do, and its legal weight depends on how courts or jurisdictions interpret cryptographic timestamping. It works best as a supporting layer of proof rather than a complete signing or contract workflow.

The best part? The cost. SignHash doesn’t rope you into subscriptions or contracts. You pay per document, and it’s less than $5. Imagine getting full legal control over a document for less than $5?

SignHash is (Probably) The Future

Overall, SignHash fills a specific but valuable niche. If your goal is to prove that a document hasn’t changed since a certain moment—especially while keeping the contents private—it’s a clean, focused solution. For businesses that need formal signatures, identity verification, or multi-party approval flows, it’s better seen as a complement to traditional e-signature tools rather than a replacement.

The canvas of commerce is transforming, with technology creating new paths of opportunity for small businesses. This digital revolution is more than just a buzzword; it’s a practical toolkit for growth and competition. From e-commerce platforms to cloud computing and automation, technology has leveled the playing field, giving small enterprises a fighting chance against industry giants. 

E-commerce: A Global Storefront 

E-commerce has transformed small local businesses into global vendors. Platforms like Shopify, Etsy, and Amazon have erased geographical boundaries, bringing global customers to virtual doorsteps. Online shopping isn’t merely a convenience, but a vast market frontier that businesses are exploring with growing enthusiasm. 

Digital Marketing: Beyond Traditional Boundaries 

Digital marketing has revolutionized outreach efforts, offering cost-effective and targeted solutions. Small businesses can now connect with their audience through social media, SEO, and email marketing. These techniques provide valuable insights into consumer behavior, fueling data-driven decision-making that ensures greater marketing efficacy. 

Cloud Computing: Powering Up Productivity 

Cloud computing has democratized access to high-end computing power and storage. Small businesses can leverage these services to optimize their operations, streamline workflows, and scale up with ease. Cloud-based software also promotes remote collaboration, a crucial asset in the modern work environment. 

Automation and AI: Efficiency Unleashed 

Automation, driven by advancements in AI, has eased the burden of repetitive tasks. From customer support chatbots to automatic invoicing, small businesses are freeing up valuable resources. AI’s ability to learn from its interactions with customers is a game-changer, enabling personalized service without straining human resources. 

AI Adaptability: The Smart Business Assistant 

Artificial intelligence is more than just a responsive tool; it’s an adaptive one. AI systems can override previously set parameters based on customer interactions, improving service delivery. This adaptability is continually improving, with AI algorithms learning and refining their responses over time. 

Tech in Michigan: From Operations to Promotions 

Tech empowers Michigan businesses to streamline operations, explore growth opportunities, and engage wider audiences. Technology underlies critical business functions including e-commerce, marketing, and even creating incentives like Michigan casino bonuses to attract customers. It’s a shining example of how technological adoption can redefine business landscapes. 

Industry Leaders: Harnessing Technology 

Industry leaders like Amazon and Google set impressive examples of leveraging technology for business efficiency. Their success inspires small businesses to emulate these strategies, integrating technology into their operations, customer service, and marketing endeavors. 

AI and Customer Service: A New Dawn 

Customer service has entered a new era, powered by AI. Chatbots and voice assistants deliver immediate, personalized assistance, enriching the customer experience. This technological intervention has proven crucial in sectors where rapid response times are essential, like retail, food service, and logistics. 

The Way Forward: An Inclusive Digital Future 

The digital revolution is far from over. As technology continues to evolve, small businesses will find new avenues to compete, grow, and thrive. By embracing this digital tide, small businesses are not just surviving; they are flourishing in spaces once dominated by industry titans. 

Deep-Dive into E-commerce 

E-commerce is not just about selling products online, but also about creating a unique brand experience. Small businesses can utilize innovative technologies like Augmented Reality (AR) to allow customers to visualize products before purchasing. Similarly, the integration of AI can enable personalized recommendations, mimicking the attention-to-detail once exclusive to physical stores. 

Demystifying Digital Marketing Strategies 

In the realm of digital marketing, the strategies are endless. Pay-per-click advertising, influencer marketing, and content marketing are just a few examples. By harnessing data analytics, small businesses can determine which strategies work best for them, allowing for refined, successful marketing campaigns. 

Cloud Computing: More Than Just Storage 

Beyond storage and computation, cloud services offer a multitude of business applications. They host software for project management, Customer Relationship Management (CRM), and Human Resource Management (HRM), among others. As a result, small businesses can employ sophisticated software tools without investing in hardware infrastructure. 

Automation Beyond Boundaries 

Automation has implications beyond cost-saving. It improves accuracy, minimizes errors, and ensures consistency in business processes. For instance, automated supply chain and inventory management systems can significantly enhance efficiency, leading to satisfied customers and reduced overhead costs. 

AI: The Ever-Learning System 

AI is continually evolving, not just from software updates but through ‘machine learning.’ This branch of AI enables systems to learn from experience, improving their performance on tasks like predictive analytics, fraud detection, and market forecasting. Such tools give small businesses a competitive edge. 

On-the-Ground Impact: Illinois’s Tech Boom 

The impact of tech adoption is vividly seen in Illinois. Small businesses, powered by technology, are reaching out to customers through personalized promotions and virtual interactions. This shift has invigorated the local economy and demonstrated the potential of technology as a catalyst for business growth. 

Inspiration from the Titans: Learning from the Best 

Amazon’s use of automation and AI in their warehouses, or Google’s reliance on data analytics for decision-making, serve as valuable lessons. These practices illuminate how technology can be effectively employed to improve productivity and customer satisfaction. 

AI in Customer Service: Revolutionizing Interactions 

AI-powered customer service goes beyond responding to queries. By analyzing customer data, AI can predict customer needs and provide proactive assistance. Furthermore, AI tools can offer 24/7 support, filling in the gaps when human operators are unavailable. 

Anticipating Challenges in Tech Adoption 

While technology offers numerous benefits, small businesses may face challenges in adopting it. These can range from financial constraints to a lack of tech-savvy staff. Overcoming these hurdles often involves investing in training and seeking cost-effective tech solutions. 

Crafting a Tech-Savvy Future for Small Businesses 

Small businesses stand on the cusp of a tech-driven future and embracing this wave of digital transformation can result in unprecedented growth and success. As the pace of technological development accelerates, it’s up to these enterprises to ride the tide and make their mark in the digital arena.

This article will discuss 6 of the most common employee engagement barriers and provide tips on overcoming them. Are you ready to take your business to the next level?

Lack of Recognition

One of the most common employee engagement barriers is a lack of recognition. If employees feel their hard work goes unnoticed, they will likely become disengaged. 

How can you overcome this barrier? Try to find ways to recognize employees regularly. This could include sending monthly awards, public shout-outs, or simply taking the time to thank employees personally.

Toxic Work Environment

One of the most common employee engagement barriers is a toxic work environment. This can be caused by several factors, such as

– poor management

– bullying

– harassment

– favoritism

To create a positive work environment, you need to promote a culture of respect and open communication. Employees should feel like they can approach management with any concerns, and management should be willing to listen and address issues immediately. Employees who don’t feel safe or valued at work will not be engaged.

Disengaged Leadership

Another common barrier to employee engagement is disengaged leadership. If your leaders aren’t bought into your company’s mission and values, they will not be able to inspire and motivate their teams.

To engage your leaders, you need to ensure they’re involved in the decision-making process and feel their opinions matter. You should also give them regular feedback and opportunities to grow and develop.

Lack of Direction

If your employees don’t know what’s expected of them, they will not be engaged. Lack of direction is a common problem in many businesses, but it can be easily fixed.

Ensure that your employees know your company’s goals and how their work contributes to those goals. Assign clear roles and responsibilities, and provide regular feedback on performance.

Using Outdated Software

One of the most common employee engagement barriers is outdated or ineffective software. If your employees are using software that isn’t easy to use or doesn’t meet their needs, they will not be engaged.

You need to invest in high-quality, user-friendly software to overcome this barrier. Employee engagement platforms can help you track employee satisfaction and engagement and make it easy for managers to give feedback.

Just make sure your software is up to date and meets the needs of your employees. Using employee engagement software will result in a more robust, more engaged workforce.

Lack of Training

If your employees don’t know how to do their jobs, they will not be engaged. This is especially true if the job requirements need to be clarified or the employees need training on how to use the tools and equipment necessary for their work.

You must provide employee training promptly and ensure it’s accurate and up-to-date. It would help if you also created an environment where employees feel confident asking questions about their work. This will help them become more engaged in their duties.

Providing quality training is essential to achieving employee engagement. Effective and customized training will help your employees learn what they need to do their jobs effectively.

Conclusion

At the end of the day, it all boils down to how employee engagement is seen and managed in your business. To ensure that you have a high-performing team, you must address each of these issues.

In addition to this list, there are also other factors like bonuses and salaries as well as benefits that can influence employee engagement levels. It is essential to look into all aspects while managing these issues simultaneously.

According to the FengOffice website

Feng Office is an integrated suite of software designed to help your organization run better. Stay connected to your customers, meet project deadlines, find information faster and grow your organization.

This is a tool that can be very useful in professional environments. We also have a paid version with professional support and a community version that we can use in smaller projects.

Install FengOffice on Debian 10

The installation of FengOffice is possible using a server that has MariaDB, PHP, and of course, a server like Apache.

1.- Install Apache, PHP 7.1, and MariaDB on Debian 10

So, it is necessary to install Apache, MariaDB, and PHP 7.1 which is the version that will not give us problems with FengOffice.

So, we have to add the repository to install PHP 7.1

wget https://packages.sury.org/php/apt.gpg
sudo apt-key add apt.gpg
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php7.list

And finally, install all the necessary packages:

sudo apt update
sudo apt install apache2 mariadb-server php7.1 php7.1-mysql php7.1-curl php7.1-json php7.1-cgi libapache2-mod-php7.1 php7.1-xmlrpc php7.1-gd php7.1-mbstring php7.1-common php7.1-soap php7.1-xml php7.1-intl php7.1-cli php7.1-ldap php7.1-readline php7.1-imap php7.1-tidy php7.1-recode php7.1-zip php7.1-sq unzip catdoc xpdf ghostscript imagemagick wkhtmltopdf

Don’t forget to configure MariaDB with the mysql_secure_installation script

mysql_secure_installation

Define the root password and answer the questions indicated.

2.- Creting the new Database for FengOffice

Now it is necessary to create a new database together with a new user using FengOffice.

Open the MariaDB shell:

sudo mysql -u root -p

And it creates the database as well as the user and assigns the corresponding permissions:

CREATE DATABASE fengdb;
GRANT ALL PRIVILEGES ON fengdb.* TO 'fenguser'@'localhost' IDENTIFIED BY 'fengpss';
FLUSH PRIVILEGES;
EXIT;

You can change the values of the database, the user, and the password on your own. The password must be strong enough.

3.- Configure PHP before using FengOffice

To ensure the highest possible stability, it is recommended to make some changes to PHP. More than anything else we will increase the resources it can consume.

So, in the files /etc/php/7.1/cli/php.ini and /etc/php/7.1/apache2/php.ini set the following values.

max_execution_time = 300
max_input_time = 300
memory_limit = 512M
html_errors = Off
post_max_size = 250M
upload_max_filesize = 200M

As you are using nano, a very quick way to do this is to press the CTRL + W keys to enable the search and make everything easier.

When you make your changes, close the editor and apply your changes:

sudo systemctl restart apache2

4.- Download FengOffice on Debian 10

Now we can download FengOffice without any problem

And after the download is done, you can decompress the file with the command unzip

unzip fengoffice.zip

Move the generated folder to the Apache root directory.

sudo mv fengoffice-3.7.0.5 /var/www/html/fengoffice

And assign the necessary permissions to the folder. Also, make Apache the owner of the folder.

sudo chown -R www-data:www-data /var/www/html/fengoffice
sudo chmod -R 777 /var/www/html/fengoffice

After this, create a new Virtualhost for FengOffice:

sudo nano /etc/apache2/sites-available/feng.conf

And add the following:

<VirtualHost *:80>
          ServerAdmin admin@your-server.com
          DocumentRoot /var/www/html/fengoffice
          ServerName your-server.com

         <Directory /var/www/html/fengoffice/>
               Options FollowSymlinks
               AllowOverride All
               Require all granted
         </Directory>

ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

Replace the ServerName and ServerAdmin values with your own.

Save the changes and close the file.

Then, activate the new Virtualhost as well as the rewrite modules and headers

sudo a2ensite feng.conf
sudo a2enmod rewrite headers

And apply the changes by restarting Apache

sudo systemctl restart apache2

5.- Secure the installation with Let’s Encrypt

If you are going to use FengOffice on a server that will be accessible from the Internet then you should use HTTPS

There is nothing better than Let’s Encrypt to generate certificates for your domain quickly and conveniently.

So, install the packages with the following command

sudo apt install certbot python-certbot-apache

Now create and add the certificate with the following command

sudo certbot --apache -d your-domain.com

Follow the instructions and at the end, you will be able to access it using HTTPS

6.- Install FengOffice on Debian 10

Now you can access https://your-domain and you will see the following screen:

Afterwards, the installer will verify that the whole system meets the requirements.

Then you have to type the values of the database we have created as well as the credentials of the new user.

Next, you will see a screen indicating that the installation was successful and then you will have to create the new user by clicking Finish.

Create the new admin user with the credentials you want.

Then you will see the login screen

And now yes the administration panel.

Enjoy it.

Conclusion

FengOffice is used by many companies worldwide as a practical solution to collaborative environments. This application is quite good and easy to install as we have noticed today

sudo apt -y install nginx

Here we’ll see two different methods to configure Nginx.

• Configure Nginx HTTP Proxy For Odoo
• Configure Nginx Using Let’s Encrypt SSL Certificate for Odoo

Step 6: Configure Nginx HTTP Proxy For Odoo

Run the below command to create a new config file for Odoo.

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

If everything ok, simply restart nginx services.

sudo systemctl restart nginx

You’ll face no error on restart if all settings are ok.

Step 7: Configure Nginx Using Let’s Encrypt SSL Certificate for Odoo

As for security reasons, it is recommended to use SSL certificate for production deployments. Let’s Encrypt provides free SSL that can be used in order to enhance security.

To obtain Let’s Encrypt SSL certificate for your domain, type

wget https://dl.eff.org/certbot-auto
chmod +x certbot-auto
sudo mv certbot-auto /usr/local/bin/certbot-auto
sudo systemctl stop nginx

export DOMAIN="erp.osradar.com"
export EMAIL="sabi@osradar.com"
sudo /usr/local/bin/certbot-auto certonly --standalone -d ${DOMAIN} --preferred-challenges http --agree-tos -n -m ${EMAIL} --keep-until-expiring

You’ll see the similar output.

IMPORTANT NOTES:
Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/erp.osradar.com/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/erp.osradar.com/privkey.pem
Your cert will expire on 2020-01-17. To obtain a new or tweaked
version of this certificate in the future, simply run certbot-auto
again. To non-interactively renew all of your certificates, run
"certbot-auto renew"
Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.
If you like Certbot, please consider supporting our work by:
Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate
Donating to EFF: https://eff.org/donate-le

Now, add a cron job to renew certificate.

15 3 * * * /usr/local/bin/certbot-auto renew --pre-hook "systemctl stop nginx" --post-hook "systemctl start nginx"

Then create Nginx configuration file.

sudo nano /etc/nginx/conf.d/odoo.conf

Modify the given data to fit your setup.

Graphite has front-end and backend that can be used to get and store the data from numeric time-series to the graph format. Main purpose of graphite is to store numeric time-series data and provide the graph of the stored data when requested. So, let’s move towards the installation process.

Step 1: Update Your System

As usual we do update your system to have the latest packages installed. To do so run the below command.

sudo apt update && sudo apt upgrade -y

Once, the update finished reboot your system and move towards the next step.

sudo reboot

Step 2: Install Docker Container Engine on Ubuntu 20.04

Type the following command after the system reboot in your terminal.

sudo apt -y install vim apt-transport-https ca-certificates curl gnupg-agent software-properties-common

Now, import the docker GPG key using the below command.

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

And then, add the Docker CE repository in Ubuntu system by hitting the given command.

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Finally, fire the below command to install Docker CE on Ubuntu 20.04 server.

sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io

Once, the installation finished add your user to the docker group. To do so, fire the given command in your terminal.

sudo usermod -aG docker $USER
newgrp docker

Make sure the installation is successfull.

Step 3: Running Graphite in Docker Container

As we’ve finished the installation of docker engine, now we’ll start docker container for Graphite. Here we’ll use the official docker repository for graphite.

Get the latest docker image by typing

sabi@Ubuntu20:~$ docker pull graphiteapp/graphite-statsd
Using default tag: latest
latest: Pulling from graphiteapp/graphite-statsd
df20fa9351a1: Pull complete
a30ee9926b20: Pull complete
51a4bd789783: Pull complete
9eb78f4a78c8: Pull complete
Digest: sha256:aaec5e5daadad64efb8039dd128e89dc6ac95bc129553427fca980a049d1fb40
Status: Downloaded newer image for graphiteapp/graphite-statsd:latest
docker.io/graphiteapp/graphite-statsd:latest

This image will contain the following parts.

• Nginx (Reverse proxy the graphite dashboard)
• Graphite(Front-end)
• Carbon(Back-end)
• Statsd(UDP based backend proxy)

Following default mapped ports will be used.

Graphite and Statsd should be handled carefully as they are very complex to setup. The docker image downloaded above help us to run & collect the stats in few minutes.

To see the available images type

sabi@Ubuntu20:~$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
graphiteapp/graphite-statsd latest 976c24bf0bc6 4 weeks ago 723MB

Now, create the following directories on the host system for persistent data storage.

sudo mkdir -p /data/graphite/{data,logs,conf,statsd_config}

Make sure to set the correct timezone and then run the following commands.

docker run -d \
--name graphit \
--restart=always \
-p 80:80 \
-p 2003-2004:2003-2004 \
-p 2023-2024:2023-2024 \
-p 8125:8125/udp \
-p 8126:8126 \
-v /data/graphite/data:/opt/graphite/storage \
-v /data/graphite/conf:/opt/graphite/conf \
-v /data/graphite/statsd_config:/opt/statsd/config \
-v /data/graphite/logs:/var/log \
-e GRAPHITE_TIME_ZONE='Asia/Karachi' \
graphiteapp/graphite-statsd

Verify the status of graphite container

sabi@Ubuntu20:~$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
420150f994b9 graphiteapp/graphite-statsd "/entrypoint" About a minute ago Up About a minute 0.0.0.0:80->80/tcp, 0.0.0.0:2003-2004->2003-2004/tcp, 2013-2014/tcp, 8080/tcp, 0.0.0.0:2023-2024->2023-2024/tcp, 0.0.0.0:8126->8126/tcp, 8125/tcp, 0.0.0.0:8125->8125/udp graphit

If you face any error, refer to the logs

docker logs -f graphite

Output:

,,..

As by default, statsd is listening to 8125 UDP port,you can change it to tcp port if you want. To do so, you’ve to set the environment variable STATSD_INTERFACE to TCP port while running the container.

Step 4: Access Graphite Web Dashboard

Access the Graphite web interface by typing server IP.

Use the pre-defined credentials to login.

User:root
Pass:root

For security reasons, change the default credentials, by typing IP/admin/auth/user/1/

You’ll get success message of password change.

So,this is how you can install graphite & graphite web on Ubuntu 20.04
