In recent days, Cloudflare, a major web infrastructure and website security company, has been wrestling with several service outages. On October 30, an update rollout to its globally distributed key-value store, Workers KV, went awry, plunging all Cloudflare services into a 37-minute-long outage1. Just a few days later, on November 2, 2023, another outage occurred, impacting many of Cloudflare's products, including its dashboard and related application programming interfaces (APIs)2. The company pinpointed a power failure at its core North American data center as the catalyst for the November 2 outage. While this hiccup was partial, with most of Cloudflare's services remaining unaffected, it nevertheless posed significant challenges3. Cloudflare's reaction to the power loss was swift, as it aimed to assess the impacts on its data centers and work on a fix, all while failing over services to maintain as much functionality as possible4. The situation escalated on November 4, 2023, when Cloudflare began experiencing either complete or partial outages across different services, further including its dashboard and APIs5. As Cloudflare scurries to restore its services to normalcy, these incidents underscore the vulnerabilities even major internet services business face, and the cascading effects such outages can have on the myriad websites and online services reliant on Cloudflare's infrastructure.
Google's Layoffs: A Cautionary Tale of Ambition and Poor Leadership in the Age of Unrestrained Capitalism
The recent Google layoffs, affecting 6% of the workforce, have sparked debates about personal ambition, poor leadership, and unrestrained capitalism. The publicly listed tech giant, once known for its "Don't be evil" mantra, has come a long way since its early days, ballooning to a market cap of over a trillion dollars and nearly 200,000 employees. But as the company continued to grow rapidly and compete for top talent, spiraling compensation packages raised questions from investors about the return on their investments. However, instead of addressing the root causes of its wasteful deployment of people, Google chose to take a blunt force approach to headcount reduction, which is unlikely to lead to improvements in productivity and may even harm the company in the long run. The way the layoffs were handled - with some employees being fired by text message and ghosted - has left a bad taste in the mouth of former employees and is a far cry from the company's original vision of serving the greater good. The pressures of public ownership, with its fiduciary duty to act for the benefit of shareholders, have driven Google down a path that prioritizes short-term profits over long-term thinking. This is a problem with unrestrained capitalism, as institutional investors with the means to take companies to court have the upper hand in shaping a company's priorities. Despite the efforts of Google's founders to maintain control and operate as a long-term-focused company, the reality of public ownership has resulted in a company culture that values profits over people trying to pick up…
Sometimes, it would be awfully convenient to grab the installer for the latest release of your favorite Github project directly from the command-line. And if it could incorporate awk, that would be great too.[1] Well, the following command-line is a pretty nifty template to do just that! You will need cURL, shipped with macOS, or Wget, shipped with Linux, for this to work. Substitute in the user or organization name, the project’s name, and the desired file extension for the <user>, <repo>, and <extension> fields respectively. Download the latest Github release (cURL) $ curl -s https://api.github.com/repos/<user>/<repo>/releases/latest \ | awk -F': ' '/browser_download_url/ && /\.<file extension>/ {gsub(/"/, "", $(NF)); system("curl -LO " $(NF))}' Download the latest Github release (Wget) $ wget -q -nv -O - https://api.github.com/repos/<user>/<repo>/releases/latest \ | awk -F': ' '/browser_download_url/ && /\.<file extension>/ \ {gsub(/"/, "", $(NF)); system("wget -qi -L " $(NF))}' Here is a quick explanation. First, cURL or Wget obtains the response from an HTTP GET request.[2] This response contains the URLs for the various artifacts for the latest release of the project. Next, awk processes the response, finding the line containing a download URL and matching the given file extension. It then removes the quotation marks surrounding the URL and downloads the file directly with cURL or Wget. It’s also easy enough to modify the match pattern for the file extension to make it more specific if need be. The following example demonstrates this by fetching the latest Linux release zip file of the Ninja build system. Download the latest Ninja release (cURL) $ curl -s https://api.github.com/repos/ninja-build/ninja/releases/latest \ | awk -F': ' '/browser_download_url/ && /linux\.zip/ {gsub(/"/, "", $(NF));…
What is swap space/memory? When the amount of physical memory (RAM) is full, swap space in Linux is used. Non-active pages in memory are moved to the swap memory if the system requires more memory resources and also the RAM is complete. While swap memory can help devices with a percentage of RAM, it should not be thought about a substitute for more RAM. Swap memory is located on hard disk drives, which have a slower accessibility time than physical memory. What is the formula to determine the required swap memory? The swap space ought to amount to 2x physical RAM for approximately 2 GB of physical RAM, and after that an extra 1x physical RAM for any kind of amount over 2 GB, yet never ever less than 32 MB. For systems with actually big amounts of RAM (more than 32 GB), you can likely get away with a smaller swap partition (around 1/2 half the physical RAM). So, if: Using this formula: A system with 2 GB of physical RAM would certainly have 4 GB of swap memory. A system with 3 GB of physical RAM would certainly have 3 GB of swap memory. A system with 64 GB of physical RAM would certainly have 32 GB of swap memory. If you intend to upgrade your RAM at a later time, creating a huge swap space partition can be particularly practical. Identifying current swap space Before you start, check if your AlmaLinux installation already has swap enabled by typing: cat…

ConfigServer Security & Firewall (CSS) is an iptables based firewall for Linux systems. In our previous tutorial read installation tutorial of CSF on Linux system. CSF also provides in-built web UI for the managing firewall from the web interface. In this tutorial, you will find how to enable CSF Firewall Web UI on your system. Step 1 – Install Required Perl Modules: CSF UI required some of Perl modules to be installed on your system. Use the following commands to install required modules as per your operating system. Debian based systems: $ sudo apt-get install libio-socket-ssl-perl libcrypt-ssleay-perl \ libnet-libidn-perl libio-socket-inet6-perl libsocket6-perl Redhat based systems: $ sudo yum install perl-IO-Socket-SSL.noarch perl-Net-SSLeay perl-Net-LibIDN \ perl-IO-Socket-INET6 perl-Socket6 Step 2 – Enable CSF Firewall Web UI: To enable CSF web UI edit /etc/csf/csf.conf file in your favorite text editor and update the following values. $ sudo vim /etc/csf/csf.conf # 1 to enable, 0 to disable web ui UI = "1" # Set port for web UI. The default port is 6666, but # I change this to 1025 to easy access. Default port create some issue # with popular chrome and firefox browser (in my case) UI_PORT = "1025" # Leave blank to bind to all IP addresses on the server UI_IP = "" # Set username for authetnication UI_USER = "admin" # Set a strong password for authetnication UI_PASS = "admin" After making changes, edit /etc/csf/ui/ui.allow configuration file and add your public IP to allow access to CSF UI. Change OUR_PUBLIC_IP_ADDRESS with your public IP address. $ sudo echo "YOUR_PUBLIC_IP_ADDRESS" >> /etc/csf/ui/ui.allow Web…
Introduction Config Server Firewall (or CSF) is a free and advanced firewall for most Linux distributions and Linux based VPS. In addition to the basic functionality of a firewall – filtering packets – CSF includes other security features, such as login/intrusion/flood detections. As mentioned CSF includes UI integration for cPanel, DirectAdmin and Webmin, but this tutorial only covers the command line usage. CSF is able to recognize many attacks, such as port scans, SYN floods, and login brute force attacks on many services. It is configured to temporarily block clients who are detected to be attacking the cloud server. The full list of supported operating systems and features can be found on ConfigServer’s website. Installing ConfigServer Firewall First we need to make sure that perl is installed yum install wget vim perl-libwww-perl.noarch perl-Time-HiRes Then we can go ahead and download CSF cd /usr/src/ wget https://download.configserver.com/csf.tgz The next step is to extract the downloaded tar archive and run the install script: tar -xzf csf.tgz cd csf sh install.sh Configure CSF CentOS 7 has a default firewall application called “firewalld”. You have to stop firewalld and remove it from the startup. Stop firewalld: systemctl stop firewalld and disable it: systemctl disable firewalld Now we can enable CSF disabling the default TESTING state: cd /etc/csf/ next open the csf.conf file using your favourite text editor - vim, vi ,nano and etc vim csf.conf On line 11 you will see that the “TESTING ” is set to “1” , make sure this is set to “0” TESTING = "0" Now we can start and enable both lfd and csf `systemctl…
I recently ran into an issue where I wanted to test a deployment using Windows Server 2019 Storage Migration Service feature. It turns out an Evaluation installation does not support storage migration service and it will not appears to be missing in the Windows Admin Center. I needed to upgrade Windows Server 2019 Evaluation to Standard edition. which is fortunately very easy! First open up a Powershell window and run as Administrator. Enter the following command: DISM /Online /Set-Edition:ServerStandard /ProductKey:N69G4-B89J2-4G8F4-WWYCC-J464C /AcceptEula DISM will proceed to make the required changes and will request a reboot. Press Y to reboot the server. Once the server has rebooted, log back in and open up Powershell again and type: DISM /Online /Get-CurrentEdition Congratulations you now have standard edition installed!
