Level1 Community Update
I figured it was a good time for a small updated and shout out for things people have been up to. Let me know if you’d like to see more of these in the future.
Some Forum Changes
Moderator and Leader Tagging
You can now mention moderators and leaders with
@leaders in case you want to get someones attention but don’t think it needs a flag, or is a question, etc. But please remember not to over use it or you’ll just end up with an angry mob of people
The FAQ is missing guidelines on how necros are handled which was brought up the other day, so we’re looking at how those will be handled and will update the FAQ to reflect how they will be handled going forward shortly.
Forum Software Update
mentioned a couple of days ago we’ve updated to the most recent software version. This has included some feature updates and a bunch of bug fixes. You can read more here.
We tend to keep up to date with releases, so might only mention it if there are large changes or useful changes for everyone to use.
A New Leader
We are welcoming a new leader to the group,
Things Going on From the Community.
There’s a bunch of interesting things going on and posted by the community which are worth checking out.
A Minecraft Galacticraft is up for people that
@wendell and co were playing on last weeks stream, you’re welcome to join. (the server info might be TL2 locked on the forum) Recent Community Game Giveaway
@Dje4321 organised a recent games giveaway (now closed) and with many people contributing keys.
A big thanks to those who contributed keys for the giveaway:
@DehydratedSlugs, @Superfish1000, @poly_salama, @AsimpleRadio, @Phantom, @MichaelLindman, @psycho_666, @MFZuul, @SlipperyVagoo, @yourwolfsdengaming, @SgtAwesomeSauce, @S1lent_5am, @NeOZeN, and others.
I’m sure we will have more in the future as well, so keep an eye out.
@Phantom and I have started on the grand three-dimensional journey of learning Blender.
This will be a catalog of our experiences as we progress. I know there are some seasoned 3D artists who lurk around here occasionally. Any feedback/pointers/insight would be greatly appreciated.
Also, anyone else who would like to learn along with us, please feel encouraged to do so and post here.
We began by following this tutorial which we were both mostly happy with:
Some of This Months Notable Picks
In the recent Linux Gaming video from L1T, Wendell made a request to see if the Level1 community could lead a project in getting some diagnostic and benchmarking tools for Linux.
Pretty light specifications:
Measuring and benchmarking performance and frame times for games and APIs.
ocat, fcat, and fraps.
Additionally, these will need to be easy to use for gamers and non-engineer types. It will also need to be modern, to handle 60+ fps and high resolutions.
So, this is a tall task, which I think is why he asked for the community to frontier forward. It looks like ocat is C++*, and I’m willing to bet the others are as well. Definitely feel free to pitch some ideas.
Golang would be another option, as they have a plethora of tools in the standard library.
Anyone up for the challenge? Got any boilerplate or ideas to begin with?
Google Wi-Fi. Google’s Answer to the Home Network.
Right now it did cost $99 but now it’s back up to $119-$129 cause the Amazon Prime day sale ended…
First off, it’s a pretty reasonable router. it has a lot of Basic goodies. it has an LED light around it
when the light is blue, that means it’s waiting to be connected. when the light is green, it means everything is ready to go, if the light is Amber, that means it has no connection to the internet and if the light is Red it means their is an error.
Here’s the screen in the settings
[edited for security]
Now for most of the tech users here, we only care about this part. “The Network and General” type things…
Here is the Advanced Settings Tab
DNS tab you can change it to Automatic, your ISP’s DNS and or a Custom One
WAN tab shows you your IP address and you have the option of setting it to DHCP Static or PPPoE
LAN tab, you have the option of changing your Router LAN address, your subnet mask, and your DHCP Address Pool
DHCP IP Reservations TAB - You can make DHPC IP Reservations
Port Forwarding: Self Explanatory
UPnP (Universal Plug and Play… devices can quickly discover each other on the network, you have the option of enabling this feature or not
NAT tab: you can set your router to be NAT or Bridge Mode: Bridge Mode is great if you bought the 3 pack Google Wi-Fi so you can connect the three routers as a Mesh Network. if you’re like Me and have just one router. you can set this to NAT.
IPV6 tab: Self Explanatory. you can enable this or disable it, if your ISP supports it.
would be nice to tinker with but this is for people that just want to get their networks setup quickly and f…
DISCLAIMER: CONCENTRATED NICOTINE IS AN ACUTE CONTACT POISON, AND ILLEGAL TO PURCHASE AND USE IF YOU ARE UNDER 18. THIS GUIDE IS FOR ENTERTAINMENT PURPOSES ONLY AND I HOLD NO LIABILITY FOR ANY INJURY OR DAMAGES CAUSED BY WHAT YOU DO IN YOUR OWN TIME
Before the avalanche of vape naysh and popcorn lung memes descend on the post: let me explain why I do this, and why it’s a fun hobby and probably a better idea than buying commercial e-liquid.
I used to be a half-pack a day smoker, and vaping was the only thing that helped me taper off. If used correctly, I feel like it’s a very viable strategy to remove your dependence on nicotine, but how the market is at present isn’t exactly conducive to health consciousness. The way e-liquid is being manufactured is essentially just an open case study on what substances/adulterants are harmful to inhale, and if you have a propylene glycol sensitivity there’s no way to reliably avoid it.
With a little research, and chemistry know-how, though, you can reduce the potential health implications of vaping and still start yourself on a path to being nicotine free. Anhydrous chemistry can be a bit daunting, so not many take this route.
This guide serves as a foundation to help those who’d rather know what they’re putting into their bodies, but can’t get the patch or other nicotine containing alternatives to work for them. I make no concrete claims about the benefits, perceived or otherwise, of this process.
With that out of the way, Here’s what you need to get started:
Basic working knowledge of algebra
amber glass containers, 4 Oz. or larger
60ml dropper bottles (the nicotine levels in this post are standardized to this container size, you will have to do your own stoichiometry and dilution calculations if you deviate from this, or the nicotine stock solution concentration)
24mg/ml 100% VG extracted nicotine (preferably natural, USP grade recommended)
organic USP/Food Grade vegetable glycerine (as close to anhydrous as i…
I figure we have The Small Linux Problem Thread, but that kind of encourages cool solutions or hacks to problems. We need a thread like the Windows section has, about hidden Windows 10 things that are awesome.
So, here’s one that I use every day that is SO FREAKING AWESOME.
tmux is a program that allows you have multiple terminals open at once and multiple sessions of terminals open.
I’m usually at my battlestation, hacking away in a terminal. Sometimes I leave, take my laptop into the living room or whatever, and ssh in to resume my work.
Ctrl + b and d will “detach” the session on the server wherever it’s at. On my laptop, I can ssh into my battlestation (or my server) and tmux ls to find the session (if there are multiples) then tmux attach -t session number
BOOM. If I had three shells open, one ssh’d into another server, one with Vim open, and another tailing logs, I’m back in the saddle, picking up right where I left off.
@wendell thanks for the tip. I used tmux for a while as a i3wm supplement. I had no idea this functionality existed until I watched your Linux Admin beta series.
So, everyone, what Linux Pro Tips do you have?
Awwwwww YEEEEEAH! It’s ma’ fak’n GO TIME!
Inspired by this thread:
I’ve decided to reinvigorate myself for not just August, BUT FOR LIFE.
Books are fun.
Books sometimes have decades of research condensed into a few hundred pages. Books allow our minds to work in the way they were intended: processing data, painting rich pictures, interpreting details, changes in tone, texture, smell, and taste.
Next time you find a book, sniff it like you’re Jack Nicholson in a Vegas sex club with an 8-ball of cocain in 1981. You’ll thank me later.
Stolen from other places:
The written version of the above video:
The goal is simple. Read one book every week for a year. The books can be anything you like, don’t like, or something you’re not sure if you like.
I am starting with something I’ve put off for a long time. I read it a while back, but sometimes you need that second run to really hammer home the message. I tend to take notes when reading, writing in margins or using a separate notebook. So I plan on reflecting and see if I’ve changed my perspective at all this next go around.
Cal Newport is a pompous Computer Science professor, but a good writer that brings good points to the table.
After this, I’ll probably start The Horus Heresy
What are you going to read? Will you take this challenge with me and start to unplug more and more throughout the year to better yourself?
I’ll update my status weekly, to keep myself and others motivated. In other communities I’ve participated in we’ve listed our books, reviewed them (optional), and discussed what we learned, for better or worse.
Join me, Level 1 Techs!
Rebuilding some things. This will just be a place for people to have a look, ask questions and scrape any bits they may like to use.
Will be dumping old front end and rewriting/designing new. Will not include user authentication right now, maybe later.
And Devember project HERE
I started rewriting the thermostat program to include outside air temp control when in auto. Also added a short delay between fan state changes to keep from cycling the unit too quickly.
Want to add in a fan cycle timer, so if the unit doesnt run for an hour or so it will run the fan for a bit just to circulate the air.
Also would like to add in something to control exhaust and intake air for free cooling and to help indoor air quality. This may be much later.
Theres lots of extra and missing pieces, not ready for use.
Look in Arduino/Controller_HVAC2
Today I spent a bit of time messing with pcb layout and schematic programs. I chose fritzing because it seems easy. I have eagle to try if fritzing doesnt work out.
This uses an opto-isolated relay board for the outputs to drive the stat wires (r,g,y,w) and theres an extra output for humidifier.
The inputs are for some cheapo 3 wire temperature sensors.
I just figured out what is probably the easiest way to view VMs with Spice protocol enabled from Windows.
I figured that might be helpful to people on this board since there’s lots of people using KVM but spending time on Windows desktops.
I pretty much always use Windows (I like Linux, but I get more done in Windows myself) so I am really happy to have this capability to view my KVM VMs when I need to and not be limited just to SSH (I guess there’s always VNC but this is easier and KVM defaults to Spice protocol, so…)
Anyway, here’s what to do:
Head on over to
https://virt-manager.org/download/ and download either 32 or 64-bit virt-viewer MSI installer for Windows (doesn’t matter which if you have 64-bit Windows - if you’re on 32-bit, get 32-bit because 64-bit won’t work…)
https://www.spice-space.org/download.html is also a good resource for all things Spice…
Install the Virt-Viewer MSI - if SmartScreen throws an “unknown vendor” error just ignore it and install anyway. If you’re paranoid, there’s a GPG key on the virt-viewer web page you can use to scan the MSI.
Then go to C:\Program Files (x86)\VirtViewer v5.0-256\bin (32-bit version) or C:\Program FilesVirtViewer v5.0-256\bin (64-bit version) and look for the executable named remote-viewer.exe
Double click on remote-viewer.exe and it’ll bring up a window. In the top bar, type the IP or FQDN and port of your Spice VM address-bar style and hit enter, like so: spice://192.168.1.200:5900 or spice://kvm.vm.localdomain:5900
That should be it, you should see the GUI of your VM now. If you have any problems, try adding a rule in Windows Firewall for remote-viewer.exe - if that doesn’t work, try the opening the port you’re using. For convenience, I pinned the icon to my taskbar since I know I’ll be using it a lot and don’t want to have to navigate to the folder every time.
There’s a ton of other apps inside the bin folder, too. I am trying to figure out how to connect using Virsh next - not that I …
So, you want to be a sysadmin, eh?
You think you have what it takes to ascend past the day to day I.T. gig? Are you tired of building computers, tweaking operating systems, and working within the rules of your parameters? Ready to design, innovate, and build architecture that powers your entire company across 14 countries?
Well then, let’s do this.

Getting Your First Gig
What is Systems Administration?
First and foremost, systems administration is about solving problems. Mathematicians use functions and formula, Data Scientists use prescriptive analytics and reporting services, the sysadmin uses systems, networks, and software stacks to solve problems. If you are looking to build awesome monitoring solutions, stand up servers for cutting edge applications, and experiment with the latest and greatest tech, this gig might be up your alley. But, unless you’re in R&D (lucky duck), those are secondary objectives to keeping the business online and solving problems for development, accounting, marketing, etc.
How can I get into Systems Administration?
A common path for becoming a sysadmin is join a help desk, become desktop support or field operations for a company. This is right and wrong, depending on your experiences and availability of computer hardware.
What are the pros of following a more traditional path?
You get your foot in the door. It has been said for decades that it’s not what you know, it’s who you know. What easier way to mosey into a sysadmin position if you’re already in the I.T. department doing help desk, application support, or desktop work?
You will have a unique perspective. Before making that potentia…
