  • How to get Battery status notification when a battery is full or low

    Linux laptops are good for Nix users, but it often drains the battery.

    I tried many Linux operating systems, but did not have a long battery life like Windows.

    Charging a battery for a longer duration will damage your battery, so unplug the power cable when it is 100% charged.

    There is no default application to notify when the battery charged or discharged, and you need to install a third-party application to notify you.

    For this, I usually install the Battery Monitor app, but it was deprecated, so I created a shell script to get the notification.

    Laptop battery charging and discharging status can be identified using the following two commands.

  • Setup a Local Web Server on Windows, Mac, and Linux

    When developing a website, a web designer needs to be able to see his webpages in the same way the end user would.

  • 5 advanced rsync tips for Linux sysadmins | Enable Sysadmin

    In a previous article entitled Sysadmin tools: Using rsync to manage backup, restore, and file synchronization, I discussed cp and sftp, and looked at the basics of rsync for moving files around. There are also a couple of other great articles here on Enable Sysadmin on tar and SSH you should take a look at. Copying files to and from remote systems and having an easy way to run a backup of something you're working on (or, for that matter, critical company data) are basic, useful tools in the sysadmin toolbox that I use again and again. Sometimes, however, you may want to do something a little more sophisticated, like move data across a less trusted or slower link. Rsync can provide encryption to protect it in transit, compression to make it flow better, and checksums to ensure you get what you were expecting.

  • How to Create a file in Ubuntu Linux using command & GUI - Linux Shout

  • How to install Virtualmin on Ubuntu 20.04 for a cPanel/CentOS-like web hosting control panel - TechRepublic

    For many, Red Hat pulling support from the standard CentOS releases had some serious side effects. One of the biggest dominoes to fall was cPanel--for many web hosting companies, cPanel is the de facto standard control panel. It offers absolutely everything necessary to manage the hosting of your every client's needs.

    Once Red Hat pulled the plug on CentOS 8, cPanel announced they wouldn't be supporting CentOS Stream. The good news is that the company is accelerating their efforts to support Ubuntu Server LTS, and should have that ready to ship by late 2021.

    For those looking to either migrate away from CentOS or are looking for something that can be used on the Ubuntu platform for now (or for good), there's always Virtualmin.

  • Partners Feel ‘Betrayed,’ ‘Taken Aback’ By Microsoft’s Direct Calls To Customers

    A California MSP learned a lesson years ago when a software vendor tried to go direct with his end users. So when Microsoft demanded contact information for his customers, he gave them an email address that went directly to him instead. Earlier this week that email account, which was set up about 18 months ago in the hopes that it would not be used, received a message from a Microsoft business development specialist offering his customer “free training.” “That’s exactly what I would do if I was trying to steal someone else’s business,” said the MSP, who asked not to be named because he fears retribution from Microsoft for speaking out. “It’s just wrong. It’s just wrong. Plain and simple.”

  • Windows 10 bug corrupts your hard drive on seeing this file's icon

    In August 2020, October 2020, and finally this week, infosec researcher Jonas L drew attention to an NTFS vulnerability impacting Windows 10 that has not been fixed. When exploited, this vulnerability can be triggered by a single-line command to instantly corrupt an NTFS-formatted hard drive, with Windows prompting the user to restart their computer to repair the corrupted disk records. The researcher told BleepingComputer that the flaw became exploitable starting around Windows 10 build 1803, the Windows 10 April 2018 Update, and continues to work in the latest version. What's worse is, the vulnerability can be triggered by standard and low privileged user accounts on Windows 10 systems.

  • Open source software security in an ICT context – benefits, risks, and safeguards

    In a recent report, contributors to free and open source software (FOSS) claimed they spent only 2.27 percent of their contribution time on security. In our latest blog post, we delve into open source software security, and discuss why it’s key for building robust and open interoperable networks. [...] Is open source software better than proprietary software when it comes to security vulnerabilities? Elias Levy, the person behind the infamous (vulnerability) full disclosure mailing list, Bugtraq, said two decades ago: “No. Open Source Software certainly does have the potential to be more secure than its closed source counterpart. But make no mistake, simply being open source is no guarantee of security”. Building and delivering complex system software without security vulnerabilities requires investment and due diligence, regardless if the code is open sourced or proprietary (see figure 1, below). As the Mozilla Foundation states: “Security is a process. To have substantial and lasting benefit, we need to invest in education, best practices, and a host of other areas”. Tools and resources are available. With safeguards in place, OSS can be used effectively at low risk to realize its intended benefits. ICT products relying on OSS must be developed using methodologies and safeguards that ensure the expected level of security is met. OSS can accelerate innovation, reduce the development timeline, speed time to market, realize cost savings, and be secure. ICT vendors must take responsibility and practice a higher level of due diligence when using OSS components.

  • Email is the messenger you should migrate to

    But the most important thing: Delta Chat allows you to communicate even with people who don’t use Delta Chat at all, all you need is an email address! If you write to someone without Delta Chat, they will just get a normal email. I would argue that even beats Matrix or XMPP.

    Conclusion: If you are concerned about security when chatting and would rather use a decentralized messenger (no silo), you are in good hands with email and Delta Chat.

To list just these accounts rather than include all of the service accounts like daemon, mail and syslog, add the -u option as shown in the example below.
