Do you love the puzzle and Linux/Unix-like system? Command line? Try ncurses based Tetris clone which is harder than every other Tetris out there. From the project home page:
Have you ever thought Tetris(R) was evil because it wouldn’t send you that straight “I” brick you needed in order to clear four rows at the same time? Well Tetris(R) probably isn’t evil, but Bastet certainly is. >:-) Bastet stands for “bastard tetris”, and is a simple ncurses-based Tetris(R) clone for Linux. Unlike normal Tetris(R), however, Bastet does not choose your next brick at random. Instead, Bastet uses a special algorithm designed to choose the worst brick possible. As you can imagine, playing Bastet can be a very frustrating experience!
From the announcement mailing list:
I’ve just uploaded a version of OpenSSL to unstable that disables the TLS 1.0 and 1.1 protocol. This currently leaves TLS 1.2 as the only supported SSL/TLS protocol version.
This will likely break certain things that for whatever reason still don’t support TLS 1.2. I strongly suggest that if it’s not supported that you add support for it, or get the other side to add support for it.
OpenSSL made a release 5 years ago that supported TLS 1.2. The current support of the server side seems to be around 90%. I hope that by the time Buster releases the support for TLS 1.2 will be high enough that I don’t need to enable them again.
ls is a command to show files in Linux and Unix-like operating systems. A ls command first appeared in a version of AT&T UNIX as well as in Multics. BSD and GNU Coreutils package provides the ls command with minor syntax changes. There is now third alternative named exa. It is a modern replacement for ls.
Groupware (also known as “Collaborative software”) is nothing but an app that helps users in everyday tasks such as calendar/scheduling, address books, email, forums, mailing lists, IM, wiki and more. The use of collaborative software in the work space creates a collaborative working environment. You can synchronize and share your files and photos easily using your hardware while maintaining privacy and security. Here is a list of 5 of them that you must know.
I wanted to generate RSS 2.0 feeds in Python. Nothing fancy but for certain tasks I needed it something that is quick and just works out of the box. I found rfeed – a library to generate RSS 2.0 feeds in Python. It is in my opinion straightforward to use.
I recently read that TCP BBR has significantly increased throughput and reduced latency for connections on Google’s internal backbone networks and google.com and YouTube Web servers throughput by 4 percent on average globally – and by more than 14 percent in some countries. The TCP BBR patch needs to be applied to the Linux kernel. The first public release of BBR was here, in September 2016. The patch is available to any one to download and install. Another option is using Google Cloud Platform (GCP). GCP by default turned on to use a cutting-edge new congestion control algorithm named TCP BBR.
Fedora Linux version 26.0 has been released ( jump to download ) after many months of constant development and available for download in various media format. Fedora 26 is a free and open source operating system includes various new features such as GCC 7, Golang 1.8, Python 3.6, DNF 2.0, OpenSSL 1.1.0 and more. Fedora 26 runs on both ARM servers and desktop boards too.
Like any good sysadmin, I kept my servers and desktop side up to date and patched all the time. However, recent Java updates have broken my IPMI KVM Java Applets on Dell, IBM, HP, Supermicro and FreeNAS mini servers. You will get an error that read as follows:
Unsigned application requesting unrestricted access to system. The following resource is signed with a weak signature algorithm MD5withRSA and is treated as unsigned.
I recently setup a small server which is running Debian 9. The purpose of this machine is to run OpenVPN server on port 443 to bypass censorship. It runs the following services and nothing else:
- Squid on private IP belongs to VPN pool (10.8.0.1:3128)
- SSH on private IP belongs to VPN pool (10.8.0.1:22)
- DNS resolver on private IP belongs to VPN pool (10.8.0.1:53)
- OpneVPN on public IP port 443 (server_public_ip_address:443)
Debian GNU/Linux version 9.0 stretch has been released ( jump to download ) after many months of constant development and available for download in various media format. Debian 9.0 is a free operating system includes various new features such as support for mips64el architecture, GNOME 3.22, KDE Plasma 5.8, LXDE, LXQt 0.11, MATE 1.16, Xfce 4.12, Linux kernel 4.9 and more. Debian 9 is dedicated to the project’s founder Ian Murdock, who passed away on 28 December 2015.
