Get Some System Information With Archey

Today’s article will be a fun one, where we figure out how to get some system information with Archey. It’s a mostly unnecessary article and Archey is definitely replicating work done elsewhere, but it’ll be fun!

Well, I think it’ll be fun…

I suppose you can decide that for yourself as you read the article. If you want to get some system information with Archey, read on (and maybe have fun)!

As regular readers might know, I’ve covered a variety of *fetch articles.

How To: Display System Information With screenFetch
Screenfetch vs. Neofetch, You Decide!
Show RAM Information With Ramfetch
Get Some Prettified CPU Information in Your Terminal With ‘CPUFETCH’

In fact, the ‘Screenfetch vs. Neofetch’ article is oddly one of the most searched articles on the site, at least from Google’s traffic.

Anyhow, Archey is like those (but written in Python, if that matters). If I understand correctly, it was Archey4 – a maintained fork of Archey. The original Archey project ceased development and now this project is just called Archey as it is no longer a fork but is the actual project.

I think I’m understanding that properly. If I’m not, hopefully, someone chimes in and lets me know the full story. Often my articles are visited by project leaders, so maybe that’ll happen in this instance and someone will set the story straight.

Either way, it doesn’t matter much – but it does explain why I’m simply referring to the project as ‘Archey’. If you check the man page, you’ll learn that Archey describes itself like:

A simple system information tool written in Python

Got it? Good! Let’s get started getting some system information with Archey!

Let’s Get System Information With Archey:

So, the first thing you’re going to need is a copy of Archey. That’s easily accomplished if you want .deb or .rpm. There are some odds that you’ll find it’s already in your repositories (like Arch or BSD). You can also use “pip” (Python packages from PyPI) to install Archey. There’s even a ‘homebrew’ version for Mac users.

Otherwise, if none of those will work for you, you might find you need the source code to build and install Archey.

This link should take you to the current release:

https://github.com/HorlogeSkynet/archey4/releases/latest

From there you can install Archey. Due to the huge variety of installation methods, I’m just going to tell you to follow the directions to install Archey. If you can’t get it installed, you can always ask for help and someone will hopefully get you sorted.

Once you have Archy installed, you can start getting system information with Archey. You just run the archey command and it’ll spit out something like this:

Achey displays system information.
I don’t think you’ll need me to explain. The screenshot should be adequate.

As you can see, Archey’s output is fairly normal. It likely reminds you of things we’ve already covered in earlier articles. That’s okay – it should remind you of things like Screenfetch and Neofetch.

Just like some of the other previously covered *fetch applications, you can take a screenshot automatically. After all, the goal of these applications is to give you some information that si easily captured as a screenshot so that you can show it off to your forum buddies.

However, possibly because I have Flameshot installed (which seems to have taken over the ‘screenshot’ command that Archey uses), I am unable to actually verify the screenshot bit. I dutifully took the screenshot with Shutter. But, the -s flag should work for other people. I tried a few times with Archey but got conflicting errors. Someone smarter than I probably have this sorted out.

I’m not going to go uninstalling stuff just to demonstrate it. If it doesn’t work for you, file a bug at the above-linked GitHub site. Also, you have some additional options with Archey. There’s nothing too fancy, but be sure to check the man page (by using man archey) to learn more about the application.

Closure:

There you have it, you have another article. This article covers how to get system information with Archey. It’s an easy and, likely, familiar task. If you’ve followed along, you’ve learned all sorts of ways to get system information.

Do you really need Archey? No, probably not… I figured I’d cover it because my site shows up in some Archey queries. If people are looking for it, it might as well be here. That’s my line of thinking, at any rate.

Disable Window Grouping In Lubuntu

Today’s article will only matter if you use Lubuntu and want to disable ‘window grouping’ in Lubuntu. I find window grouping an annoying ‘feature’ and look to turn it off whenever I come across it. If you’re like me and want to disable window grouping in Lubunt, read on ’cause this article is for you!

I’m not sure how well I can format this like a normal article, but let’s start with the basics and see where things end up.

What is ‘window grouping’?

Window grouping is when your desktop groups similar applications together. If you have 3 instances of Firefox open, you’ll only have one instance shown in the panel (taskbar). If you click/highlight that one instance of Firefox, you’re then able to pick which of the Firefox instances you want to bring to the front.

This is an example of window grouping, where I have multiple instances of PCManFM-Qt open:

window grouping
That’s ‘window grouping’. Ugh…

I dislike this feature a great deal. It slows me down. It doesn’t reduce clutter, it adds clutter where I don’t want it. If you like window grouping, by all means, enjoy the feature.

If you are like me and find it to be an annoyance rather than a benefit, I have good news! The good news is that it can be turned off! If you’re using something other than Lubuntu, you can probably also turn it off. If you’re using another distro, a distro that’s using LXQt, you can also follow these directions.

Anyhow…

Disable Window Grouping In Lubuntu:

If memory serves, and it has been a while, if you were using Lubuntu during the LXDE days (no longer supported in any iteration of Lubuntu), you’d disable window grouping through PCManFM. This is not the case with modern Lubuntu. The current Lubuntu, and all supported Lubuntu versions, uses LXQt and it’s a different process to disable window grouping.

You can right-click on the bottom panel and select “Configure Panel” (you may have to mouse around a bit to find an empty place in the panel). From there, you’d click on Widgets (on the left) and then on “Task Manager”.

Alternatively, if you have a nice blank space in the task manager section of your panel (the bit of information at the bottom of the screen), you can skip the above step because you can just pick ‘Configure “Task Manager”‘ from that pop-up.

Either way, you end up at the following screen, at which point it should probably become obvious. Find and disable the window grouping option. It will look like so:

there's an option to disable that window grouping feature
Just un-tick the box and you’re on your way! Hit the close button.

When you’ve done that, the changes will take effect immediately and you can just hit the close button, happily going about your day without that silly window grouping feature. Just for completeness, it’d look like this:

the lubuntu task manager without window grouping enbled
I prefer it this way. I am not a fan of window grouping. It’s pretty easily disabled, thankfully…

If you decide you want to keep the window grouping, it’s easily reversed. You can also adjust other features while you’re there, should you want to do so. If you get there via the “Configure Panel” option, you can go through the “Widgets” and customize them as you see fit. You can also add and remove them while you’re there.

Closure:

Hey! There you go. You have another article! This time we’ve not even used the terminal! This time, we’ve just decided to learn how to disable window grouping in Lubuntu. It’s pretty easy once you know how to do it and what the feature is called. It’s one of the defaults that I change soon after I do a fresh installation.

How To: Make Google Chrome Use Less RAM (UPDATED)

Today’s article is going to be a brief article about a previous article, where I gave you one way to make Google Chrome use less RAM. Consider this an updated article. So, if you’re trying to make Google Chrome use less RAM (and power, I guess) read on!

As tech goes, the situation has changed. As the tech changes, so too must we change our reactions to said changes. The thing with tech is that it never stands still, something that I (for one) appreciate.

The article in question is about making Google Chrome use less RAM. This applies to other browsers, but I concentrated on Chrome. Here is that article:

How To: Make Google Chrome Use Less RAM (And Other Browsers)

In that article, I recommended folks use the “Auto Tab Discard“ plugin. That recommendation has not changed. It’s a great add-on that will discard unused tabs, saving you both RAM and some power (which is useful for mobile devices).

Now, Google (along with other browsers) have enabled a new(ish) feature. Basically, to save power, the browser does what Auto Tab Discard does – it puts unused tabs to sleep. So, when you open those tabs that were sleeping you will need to wait a moment for them to reload.

That’s not a problem. The problem is, Google does this indiscriminately by default. Chrome does seem to make an exception for tabs that are playing audio or video, but all other tabs are fair game and will be put to sleep.

I repeat, all other tabs are fair game. They can and will be put to sleep. That’s downright annoying when you distinctly want to keep some tabs from going to sleep.

Fortunately, you have options.

You can disable this feature in your settings and continue using an extension like “Auto Tab Discard”. That’s a fine choice. That was my choice. It’s probably the wrong choice, but it is a choice.

Your other choice is to manually add sites to the whitelist, telling Google to keep those tabs open. So, you won’t need the extension if you choose to do it this way. This is probably the best choice. This is the choice I did not make.

I’ll show you how to make that choice, and kinda format this like a ‘regular article’…

Make Google Chrome Use Less RAM:

For once, you don’t need to open a terminal!

Instead, open Google Chrome. Then, click on the vertical three-dot menu in the upper right, and then you need to click on “Settings”. When that tab opens, click on “Performance” (on the left) and the rest should be fairly obvious.

If you’re like me, you can just disable the feature. That looks like this:

disable the power saving feature for Google Chrome
At this stage you can modify your settings as you see fit. I’ve turned the feature off. Go me!

If you want, you can keep the feature enabled (it was enabled by default at my house) and just add your favorite sites to the list of sites that always remain active. I don’t feel like messing around with it, so I’ve simply disabled the feature and opted to keep the extension.

I suppose that might mean I use a little extra RAM, I haven’t tested but it’d be a very trivial amount and I quite like the GUI offered by the installed extension. When I next do a clean install, I’ll probably just let the browser deal with it instead of using the extension.

Other browsers may use similar tactics to save power (and free up RAM, the two are related). As of the time of this publication, this was not yet a feature that’s in Google’s opensource counterpart Chromium. Right now, this appears to just be a function in the proprietary version, but tech changes and that too may change.

Closure:

And, well, now you can see why this is an article all of its own. It was more than I could reasonably add as an update to the existing article and was enough information to make a new article. After publication, I’ll update the previous article to link to this article. I hope… Hopefully, I remember to do that.

Hmm… I think I forgot to do a ‘meta’ article in February. February is a pretty short month, plus I’ve been otherwise distracted. But, I’ve not been too distracted to skip a publication date! We’re rapidly approaching the two-year mark. It has been a pretty good ride!

Visualize Your Network Traffic With ‘darkstat’

Today’s article is a fun one, an article where you’ll learn how to visualize your traffic with darkstat. It’s a fun little tool that lets you graphically visualize your network traffic in your browser. While it’s likely more of an enterprise-level tool, there’s no reason you can’t use it as a home user.

So, if you’d like to learn how to visualize your traffic with ‘darkstat‘, read on and I’ll do my best to explain it. 

There’s a lot to the tool, but darkstat defines itself in the man page as:

darkstat – network statistics gatherer

We’ll only be using darkstat to visualize your network traffic in the browser, but there are quite a few options available. You’ll want to check the man page after you’ve got darkstat installed and have learned its basic usage.

I’ve previously covered tools like VNstat, which lets you monitor your bandwidth usage. You can even helpfully draw some graphs with the tool. This is quite different. You’ll see…

Visualize Your Network Traffic With ‘darkstat’:

This article requires an open terminal, like many other articles on this site. If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open.

First, you need to install darkstat. It should be in your default repositories for many of you. To save time, I’ll show you how to install it in Debian/Ubuntu-based distros. Just adjust the command to suit your system’s package manager:

With darkstat now installed, you need to start it – so that it monitors your network traffic. To do that, you’ll need to know the name of your network interfaces. It just so happens that I wrote that article last time:

How To: Show Your Network Interfaces

Armed with that data, you want to start darkstat and the format is:

So, for example, you might end up with one of the following commands:

Or maybe this type of command for a wireless connection:

After running that command, you’ll then want to open the following URL with your preferred browser:

http://0.0.0.0:<port_number>

If you used the port above, you’d connect to:

http://0.0.0.0:8080

The results should look something like this:

darkstat in operation
The output of the graph should be easy enough to understand.

You can also opt to see the hosts, those servers you’ve connected to, by simply clicking on the ‘hosts’ link. That’d look something like:

 

darkstat in action, showing the hosts
As you can see, this one shows the hosts you’ve connected to.

The darkstar application will run quietly in the background. It’ll keep running until you tell it not to. One way to kill darkstat would be:

As I mentioned above, darkstat has a number of different options. There’s a bunch more to it, but this is about all your regular user will need to visualize their network traffic. Of course, run man darkstat to view those options.

Closure:

There you go. You have another article, this one less short than the recent articles. I am not well, but I presume I will be. In the mean time, we’ll continue to have articles for as long as I’m able. This time, we learned about how you can visualize your traffic with darkstat. Who knows what the next article will be about.

Another Way To Find The Binary For A Specific Command

In today’s article, we’re going to learn another way to find the binary for a specific command. This won’t be a very difficult article. It’s an article that will be easy enough for even new Linux users to follow. So, if you want to find the binary for a specific command, read on!

You’ll find some similarities between today’s command and the ‘which’ command, which we used in this article:

Find A Command’s Binary

Well, we’ll use the ‘whereis’ command in this article. The man pages for the ‘whereis’ command describe it ‘whereis’ thusly:

whereis – locate the binary, source, and manual page files for a command

You may recognize the command, as we’ve used it to find the man pages for a specific command. In that article, we discussed the possibility of using the ‘whereis’ command to do just this, but I feel it deserves its own article. The first article merely mentions the possibility, so an article specifically discussing this command’s use like this makes perfectly good sense to me.

So, let’s learn another way to…

find the binary For A Specific Command:

As you might have guessed, the ‘whereis’ command is a command used in the terminal. As such, you’ll need an open terminal. Just press CTRL + ALT + T and your default terminal should open.

Now, with your terminal now open, you can try to find the binary for a specific command. Let’s say you want to find the binary for ‘grep’. Then the command would look like this:

The output of which would look a whole lot like this:

whereis command finding the binary for grep
Where is grep? There it is! This will probably not work for Waldo. Or Carmen Sandiego. 

The extra fields are where the man page and info pages are located, and the first field is the path to the binary in question. So, if you want to find the binary file for Firefox, the pattern is:

So, for Firefox specifically, you’d run:

However, if you just want to find the binary for the specific command, you’d use the -b flag. That’s all you need to do in this case. It looks like this:

And that will output just the binary file’s location without the additional fields of man pages and info pages. See? It’s pretty easy after all.

Closure:

Well, there’s another article. This time around, we’ve learned another way to find the binary for a specific command. It’s another article in a long list of articles, indeed a growing list of articles. So, well, there’s that… Which is nice…
