  • Celebrate Sysadmin Appreciation Day today

    Happy Sysadmin Appreciation Day, and thank you for all you do. When email is flowing, databases just work as they should, and the network is screaming (in a good way), you can focus on more challenging things, like how to automate tasks to make your sysadmin life easier.

    But when things break, and we know they will, it's all hands on deck to fix the problem and find the root cause, so it doesn't happen again. Sometimes, you'll find that elusive answer, and sometimes you put your hands up and move on to the next fire.

    Here at Enable Sysadmin, we're building a great community of authors who want to share their stories, their expertise, and learn from each other. In May 2020, we officially launched our Sudoers program to recognize our core contributors, and we invite you to check it out and join us.

  • July 31, 2020: Celebrate “System Administrator Appreciation Day” Today

    Ted Kekatos, a System Administrator by profession got inspired by an Advertisement in Hewlett-Packard Magazine where an Administrator is greeted in the form of flowers and fruit-baskets by thankful co-workers for their new printer installed.

    Kekatos idea was further recognized and promoted by lots of IT organizations and professional including the ‘League of Professional System Administrator‘, SAGE/USENIX, etc.

    The first System Administrator Appreciation Day was celebrated on July 28, 2000. And since then celebrating System Administrator Appreciation Day every year gets a worldly recognition and today we reached the figure 21st.

  • What sysadmins wish their co-workers knew about their jobs

    You have a problem, and reach out to the help desk or your friendly neighborhood admin. It's a quick fix, you're sure, but ugh they want you to file a ticket! What a pain, right? It might sound like they're giving you the cold shoulder but that's (usually) not the case. Admins want users to file tickets for a number of reasons.

    First of all, it helps them manage their time. It's hard to focus on longer projects when you are pelted with "this will just take five minutes" requests all day. Also, other people have been waiting for their ticket to be handled.

    Secondly, admins may need to account for their work and demonstrate that they are -- in fact -- busy and not just playing Doom Eternal all afternoon.

    Also, it helps keep track of problems that crop up frequently and assists with institutional memory. A well-kept ticketing system with a good search tool can help admins identify long-term problems that need fixing, and reduce the time to fix problems in the future by documenting how they were fixed today.

  • The sysadmin's journey: A series of unexpected events

    As part of the 21st annual System Administrator Appreciation Day celebration, I want to share these four pillars to help you improve your skills, just as they did with me.

Has Ubuntu 20.04 Finally Come Far Enough to Take on Windows? It Sure Seems Like It

Filed under

Ubuntu

Microsoft Windows has become the default operating system on Laptops and PC. So much so that Laptops now come with Windows pre-installed. Previously it used to be the case that many laptop manufacturers used to offer their products with no operating system or DOS. Since Windows 10 came into the world everything changed. You can run Windows 10 for free and get all the updates as well and without using any cracked versions. One could even argue that Microsoft went the Google route with Windows. So is windows better now or not?

Well, it certainly seems that offering your product for free does come with a few compromises. One of the biggest ones is the compromise on Privacy. Most people are just average users who buy a machine and just use it without reading the terms of service and don’t tinker around with the settings. So is it worth it to use Windows still? The answer depends from one person to another but most users will argue that Windows has a polished UI and as a ton of support and software that will run flawlessly on the OS. That aspect of the argument is true if you are a content creator or video editor but if you are a developer or just a tech nerd then it might not be the case.

  • My Thoughts On GNU Guix After Three Days

    I have spent several hours each of the last three days playing around with GNU Guix ( mostly watching packages build Big Grin ). I have it running in a VM and on a Lenovo Thinkpad. There is a lot to love about Guix, but there are also some challenges with it. Some of the problems I initially had were configuring Guix to recognize new window managers that I installed. Also, running a "make install" doesn't work on my Suckless builds. And qtile isn't packaged for Guix and a "pip install qtile" fails on Guix. But I'm still having fun!

One of the primary testaments to the success of Linux is its amazing dominance in the area of supercomputing. Today, all 500 of the world’s top 500 supercomputers are running Linux. In fact, this has been the case since Nov 2017. I know this because the TOP500 organization has been tracking the 500 most powerful commercially available computer systems since 1993 and their data documenting Linux’ takeover of supercomputing since 1998 is nothing short of inspiring. A graph of Linux' ascension is available on this TOP500 page.

Free software in business: Success stories

Filed under
GNU

Even though the vast majority of software development and news articles on technology still predominantly focus on proprietary software, public pressure is increasingly shifting the conversation to include ethical considerations. Whenever you feel that free software is not making strong enough waves, I urge you to look at the LibrePlanet conference video collection (or listen to the talks), to strengthen your belief. Making free software a kitchen table issue in every home can at times seem like an insurmountable challenge, but there are so many community members doing incredibly inspiring work driving user freedom forward.

This is why we have been updating our "Working Together for Free Software" pages in the last few weeks, with new testimonials from activists and enthusiasts. We have heard why people believe in free software, and how free software can make a difference in all industries. This third blog post in the series inspired by interviews with community members will bring some attention to the success that people have had advocating for free software through their occupations. It manifests how appeals to user freedom, and successful free software implementations, are driving forces behind the advancement of businesses all over the world.

Want to run Mac OS 8 on Linux as an Electron app? Well, you can anyway

Filed under

Mac

After creating Electron-based version of Windows 95 in 2018, Felix is back with a new virtual machine package (and a new apology for creating it).

Called macintosh.js, Felix brings Apple’s ancient Mac OS 8 system to the masses via the medium of JavaScript and everyone’s favourite app creation framework¹ Electron.

His free-to-use-but-don’t-ask-me-if-Apple-approve version of Mac OS 8 runs like a champ on Windows, macOS and Linux (I tested it on the latter). It runs as a standalone app that boots the OS up directly, i.e. there’s no need to fuss around with installers or set up dialogs).

“The virtual machine is emulating a 1991 Macintosh Quadra 900 with a Motorola CPU, which Apple used before switching to the PowerPC architecture (Apple/IBM/Motorola) in the mid 1990s,” Felix says of his effort.

A suite of era-specific software and games is bundled inside as trials, demos, or shareware. This includes Adobe Photoshop 3, Adobe Premiere 4, Netscape Explorer, Duke Nukem 3D, and plenty more.

While there’s no working internet connectivity (meaning the bundled copy of Internet Explorer must go unloved) this is a functional version of Mac OS 8. All of the apps work; this isn’t a superficial reconstruction with the veneer of usability — it works.

IPFire 2.25 - Core Update 148 is available for testing

Filed under

Security

As we have already pre-announced some time ago this side-project inside the IPFire Project is finally ready for prime time.

It comes with a new implementation to build, organise and access a highly optimised database packages with loads of helpful data for our firewall engines, as well as our analytics to analyse where attacks against the firewall are originating from.

With it, IPFire can block attackers from certain countries, or do the opposite - only permit access to certain servers from certain places. Combining rules with the rate-limiting feature allows to limit connections from certain locations which is very helpful for DoS attacks.

No new features have been added, but those that we had have been massively improved. The database is now being updated once a week which makes it more accurate and we no longer require complicated scripts to convert it into different formats to be used in different parts of the operating system.

Instead the database can be opened and ready extremely quickly which allows access in realtime making pages on the web user interface load significantly faster.

We hope that many other projects choose to use our implementation as well, since we have chosen a truly open license for the data as well as the library that works behind it.

I will talk more about this in a later blog post and explain to you the advantages of libloc.

Open Hardware With Arduino: Counter and MKR ZERO

  • Keep track of your laps in the pool with this Arduino counter

    PeterQuinn925 swims for exercise, and to train for the occasional triathlon, but when doing so he often zones out and forgets how many laps he has swam. To solve this problem without spending a lot of money on a commercial solution, he created his own counter using an Arduino Nano and an ultrasonic sensor. The sensor detects when a swimmer approaches, and the system calculates distance based on this, assuming that a lap is roughly 50 yards or meters. This info is announced audibly via a speaker/amplifier using an Arduino speech library and is shown on a 7-segment display.

  • Recreating Rosie the Robot with a MKR ZERO

    While 2020 may seem like a very futuristic year, we still don’t have robotic maids like the Jetsons’ Rosie the Robot. For his latest element14 Presents project, DJ Harrigan decided to create such a bot as a sort of animatronic character, using an ESP8266 board for interface and overall control, and a MKR ZERO to play stored audio effects. The device features a moveable head, arms and eyes, and even has a very clever single-servo gear setup to open and close its mouth.
