How to enable suspend-hibernate in Alpine Linux

Yes, I'm still trying and experimenting with Alpine Linux and gave it a full install (sys mode) it in the machine I found from the trash a few months ago. FreeBSD is still safe and sound since I'm using another HDD that I also found on the trash.

A laptop is not a virtual machine, so power management is necessary to keep sessions alive as human beings go to sleep or to work. Can you do that in Alpine? You bet. Here's how I did it:

  1. Edit /etc/apk/repositories and uncomment the lines containing the community and edge/testing repositories to enable them (along with 90% of all the packages available for Alpine).
  2. Install elogind from the community repos with apk add elogind. This is the clone of systemd's elogind but only the bare minimum to play nicely with Alpine's OpenRC.
  3. Start the elogind service with rc-service elogind start
  4. You now can suspend the system with sudo loginctl suspend and hibernate to RAM with sudo loginctl hibernate.

The end result is a power management system similar to Artix, with one difference: you need to sudo it. I'm not sure how you can remove this requirement, though I know it's possible (in Artix a regular user can do without it). The closest I've got was to edit sudoers and remove the password requirement (sudo is still required).

Anybody got any ideas?

Happy World Penguin Day!

April 25th is World Penguin Day, the day when Adélie Penguins from Antartica begin their migration northwards in search for food, giving continuity to the species interesting lifecycle of hunting, mating, birthing and raising their own.

Tux, the Linux Mascot

Though the similarities are little in my view, I feel we Linux Users should pay more attention to this amazing bird that we have taken mascot of, not only for the Tux connection but also due to the fact that climate change extinction will likely start affecting those guys first before other species realize it's too late.

So this Sunday, take the time to appreciate a little more of these amazing species, just like we usually stop to appreciate the impact of Linux and the Free Software movement in our lives. Perhaps have a look at the March of the Penguins documentary, perhaps there are some full videos available on YouTube.

Me, I'm going to try out Alpine Linux on another machine and see how it goes as a desktop.

Happy World Penguin Day 2021!

Podcast episode 13: Installing and Setting up Alpine Linux

I've been recently talking a lot about Alpine Linux, my newfound love in Free Software, and my favorite distro at the moment. Some people are curious about trying it, but are not sure where to start. To that, my recommendation is always this: try it in a VM. The image is about 100MB in size and you need less than 300MB RAM to run it. You can't go wrong!

In this episode, I explain some of the different modes of install of Alpine and walk through the install steps (spoiler alert: it's really easy).

"How Linux works

I remember reading this book way back in 2016 and it helped me understand quite a bit what makes Linux click together:

How Linux Works by Brian Ward

However, only reading is not a good exercise as actually getting your hands dirty, and implementing, changing and operating stuff. This means that a follow-up exercise of sorts should happen later... maybe with Alpine or even Linux From Scratch! I might even re-read the whole book.

Giving Alpine a try on the Raspberry Pi

After trying Alpine Linux on a virtual machine and pretty much falling in love with it, I decided to step my game up and try it on some bare metal, and installed it on my Raspberry Pi model B from 2012. After all, at a single core and 512 MB, it seems to be the right match for it.

I couldn't be more right. Snappy, light and versatile, this distribution is amazing for the resource-slim platform and it seems to run even more smoothly than FreeBSD on it. And the package management is blazing-fast.

There's only one small tricky bit, though: the installation itself. Unlike other Raspberry Pi-oriented distros, where you pretty much burn the boot-ready contents to the SD card, you must pretty much do everything from scratch with Alpine. It's not exactly "hard," just a little more work compared to the others. The steps are greatly detailed on their Wiki, and are roughly as follows:

And with that, you can insert the SD card on the Pi and then you'll be ready to setup-alpine and do an installation on it normally. Just don't forget to lbu commit at the end of it and you'll be ready to rock after reboot!

The "technical philosopher" and the IT market

As much as I enjoy or write about it, I still don't see myself as a "technical" person when it comes to Free Software. Time using it does help it a lot, but come down to it, there's lots of things I don't understand how they work or perhaps more precisely, haven't had the motivation to look up.

I think my position is better described as: a Technical "Philosopher" kind of person, who writes about how free software can help individuals and perhaps even change the world, while providing some tips and tricks that can become technical themselves. However, I'm not much of a developer type and perhaps of limited Sysadmin knowledge so I wonder if there are still spaces for people like me in the world of IT.

Will job offerings for "Unix Hacker" or "In-house helpful hacker" start appearing? Because that would be I think the most appropriate title for me, but I wonder if any HRs would approve of such titles.

Do you consider yourself a technical philosopher type? How best do you fit the "corporate" IT world - or do you think it even matters?

Fixing mouse issues with VirtualBox

Sharing this just in case if you get this issue when test-driving OSes with Virtualbox (my favorite choice in trying out new Linux distros and OpenBSD): how to restore the mouse on the guest in VirtualBox

Happened to me and freaked me out for a moment. Turns out that the solution, like the previous issue of maximizing the screen, is much more low-tech than it seems. No fiddling with config or command-line options, just go to "System," "Motherboard" and change the Pointing device from Tablet to PS/2 Mouse. Reboot the guest and voila.

But why the fuck was this switched to Tablet mode as a default in first place? It doesn't even make sense however you look at it. PC emulates PC, guys...

Free Learning Programming resources to start hacking on a budget

Just came across this Free-as-in-freedom collection of Programming Languages resources (books, guides, etc) in the form of a Github Awesome list, of which most if not all are freely available on the internet.

EbookFoundation/free-programming-books

I wouldn't exactly call some of them "books" as per quality and quantity, but most are very concise guides, or cover specific aspects of programming that physical books tend to oversee, like Graphics Toolkits or platform specific stuff.

Oh, and this is not limited to programming either, though, just browse the parent repository and have a look yourself (you're welcome). I know I will.

Analysis paralysis with Linux

I'm currently running on what I believe is a case of analysis-paralysis with Linux: too many things that I want to learn/try, but due to a limited time shared with my other responsibilities of life, I don't know where to begin. This might be some kind of "first world problems" I know, but it still sort of sucks. But it's sort of the good suck, where my attention is divided into things that are constructive.

Akihabara Live Tooting finished

Thanks to everyone who followed up the live tooting at Akihabara where I went around looking for interesting computer stuff and parts to look and buy. I had fun, and hope you did too.

It was fun doing, but I sorta feel a little guilty for using my phone so much (but then, if it was with an old fashioned camera, it wouldn't be exactly "live").

If you don't host it, how can you be sure you own it?

"We get all of this great stuff, and for free! I mean, how do they manage it?"

ZDNet: Yandex said it caught an employee selling access to users’ inboxes

Another reason why ownership of your own data, and its protection through the means of encryption, is paramount in importance. Technology may mask this point, and abstract away who else has access to the stuff you upload, but the importance has been and always will be there.

And by the way, this is not the kind of stuff that can get guaranteed protection with the "Protonmail approach" of "supposedly end-to-end encryption" either: even the German "champion" provider Tutanota was forced to backdoor one of its users too.

Part of the reason why this problem is allowed to exist is how email itself is structured: thanks to spam, it's practically impossible to self-host, so you have to defer it to the "Big Three." I don't know the solution to this yet, but I presume it has to do with going with a peer-to-peer model, where you own both the data and the infrastructure required to use it.

Featherweight and lightweight browsers

Getting to use the Raspberry Pi Model B from 2012 in a graphical mode again makes it feel like I'm coming back full circle back to 2010 and looking for lightweight Graphical programs to do my computing in any platform I want, independently of how many resources I have there.

This time, it's up to browsers. Going command-line only for a week did teach me that it's possible to survive there, but sometimes seeing other colors and images does add to the whole experience. So here's a quick list summarizing my findings about lightweight graphical browsers:

Insulting move, even more insulting explanation

If there's one thing that pisses me off that pisses me off more about corporate PR people than their marketingspeak is when they try to "talk down" to customers to hide their true message and intention.

"We're sunsetting $SERVICE starting from next month"

Oh yeah, that kind of crap. This though, seems to be the latest, and really does take the cake in my opinion: ISP imposes data cap, explains it to users with condescending pizza analogy (from Ars Technica).

"You've already had your share of bits and bytes (pun intended!!1) of $SITE this month, Billy! Gotta wait until your next allowance comes in!

Not only they're doing an apples-to-orange comparison (scarce physical goods like food vs digital bits that by definition cannot be scarce), but their way of handling the whole situation is absolutely insulting.

Once there was silent traffic shaping: you'd notice that "something" was going slower with your browsing, but wasn't quite sure, and the ISP sort of shrugged it off. Now, though, thanks to the obliteration of Net neutrality, they don't have to hide it. But hey, don't be surprised if your customers start giving you the finger when you patronize and talk down to them.

2021/04/04, 05:45: Beginning OpenBSD

I might have come full circle in my trial of OSes yesterday night by trying out OpenBSD for the first time, after about 11 years of Linux and about one month of FreeBSD usage.

I frankly have no expectations of what to find in this interesting and apparently much more secure OS, but just want to have some fun and see what I can do with it. So far, the install was very straightforward, very much like the FreeBSD installer, and there were some interesting install messages explaining where to get help, documentation, etc signed by the man himself - Theo de Raadt. Granted, this is just like an automated email sent out after a purchase, but still, seeing his name welcoming you does give some warming to the whole thing.

Let the learning (and fun) begin again!

2021/04/03, 09:33: yet another documentary on Social Media manipulation

A subject that has been overexposed and almost overblown (much like privacy after the Snowden Leaks in 2013), manipulation of social groups on Social Media has had a fair share of its reports and documentaries along the years.

Here's another one, though, plainly available on YouTube (link points to an Invidious instance). At this point, "The Creepy Line" is more of grab-the-popcorn and head-nodding for those of us literate about privacy in the modern world, but at least I think I can use this for my "weekend watching."

2021/03/31, 10:04 - loosenin' up the web

As part of my journey to try to limit my mindless wandering of the web without a goal, I realized that the barebones model of plain web pages without barriers (ex: having to use a certain device, a platform, or even a specific protocol) is the best way to make the web more "writable" and unfiltered.

Plain text files hosted in a web server that serves HTTP requests. That's all you need to "speak" today.

No distraction, no hiding, no manipulation and almost no way to track you. That's my goal in publishing from now on, and in obtaining interesting content. Therefore, I'll build a web feed for this so you can read it absolutely barrier-free, and only integrate Mastodon/Diaspora for convenience.

This essentially makes my content write-only as this backend is purely static, but that's part of the goal. And while there are similar propositions for this goal including twtxt, I think mine is a simpler (and more modest) goal.

2021/03/31, 07:08: "Write-only"

To fight the "addictions" that dealing with a lot of web content has caused to me, I'm trying to make an effort to from now on adopt a write-only stance to my interaction with the Internet.

I find that too much of the internet nowadays is exactly the opposite: designed and carefully engineered so that you can may only consume it like a TV feed. Not only that way providers can dominate your attention, but they also are able to passively manipulate you with feelings like lust, fear, guilt or envy to keep consuming more of it. And unlike TV, they don't have to force you to keep watching the show - you will voluntarily keep going back for more.

How do you break away from this? How do you rid your mind of this distraction and start getting more meaning in your life? Jolly good question, but I think part of the answer lies in becoming more active and creating rather than consuming.

From now on, I'll switch to a more "write-only" approach to my internet experience, posting more and reading less. This feed will be my communication with the outer world, and I may make an RSS Feed just for it.

See you around!

Some of us like to say they "left" the reach of Social Media because they don't participate in those surveillance-laden websites, but in reality, they're still in the net and they just don't realize it. How?

Messaging apps.

You can't name a single major messaging app nowadays that is not tied in any way to a major tech giant, which means that any time you use it, you are providing them with your data one way or another. And what's worse, this is a much harder trap to escape from because they have pretty much all the people you care about held in ransom (family, friends, potential employers...). And let's not forget that all messenger apps today are some sort of a social network themselves (status, follows, broadcasts...)

This is an ugly, but important truth that exists nowadays that we don't like to admit: unless we quit messaging apps as well, we'll remain in the hands of surveillance capitalists. I am yet to find a solution for this, but it seems pretty clear that asking people to use proper messaging solutions that respect your freedom is a losing battle - they won't switch.

In the meantime, I'm letting everyone else know that I'll be on my email address. No privacy? None in those "encrypted" messaging apps either, so might as well.

And the saga continues - learning FreeBSD one command at a time.

Turns out that suspending the system is not that bad, in fact you can do it via command-line even on the console, like this:

acpiconf -s 3 # must be root

My guess is that you can probably edit your /etc/sudoers file to include yourself and that command specifically as a NOPASSWD entry, and then be able to issue that command without hassle (a-la Linux's loginctl), which then would allow you to run the following to "lock" the screen upon suspending:

acpiconf -s 3; logout

Next step is to bind this to some action and run this graphically. Or use it with a power manager, that's probably better.

Learning FreeBSD one command at a time: if your sound isn't coming from the right speaker, or you want to change its source, the sysctl hw.snd command is your friend.

For example, to set the sound to go through the 3.5mm jack, run:

sysctl hw.snd.default_unit=1

And to switch back to the the other PC speakers:

sysctl hw.snd.default_unit=0

There's actually a lot more you can do with sysctl, which is great. That way you don't have to memorize the syntax of many different programs for administration tasks. Off to learn more, I guess!

Increasing eye candy when performing work in a console-only environment: change the prompt cursor back to the blinking block like in graphical terminals. Run the following command as root:

Valid values are anywhere from 0 to 7, and you can try different solutions to best fit your needs. This may only seem to be a small thing, but it helps bring back that old familiar feeling of graphical terminals into a workflow done completely inside the Linux Console.

It's getting clearer to me now that the ZIM format is the future of information storage. Spearheaded by the Kiwix Project originally as a way to read Wikipedia offline, its reaches are now far beyond the original scope, and virtually any content (text or not) can become compressed and quickly-searchable knowledge.

Just have a look at the collections listed by the Kiwix wiki to see how much information is out there, ready to be read in an offline manner without the need for a connection. There are ZIM files for Stack Exchange QA sites, and even TED talks (!).

After searching so long for a solution as to how can I pipe content in and out of the tmux buffer, I finally found a sane, simple answer. And what's best, it is built-in inside the tmux functions.

Simply put, I wanted a way to load the "clipboard" of tmux by piping output into it, much like you can do with xclip or xsel like command | xsel -ib and then that output would be available for you to paste with standard Ctrl+V. And yes, you can do it using only the tmux buffer too:

command | tmux loadb -

Now you can paste the output of command into any tmux pane with the Prefix Seqquence + ] combination. Now, why would I want to do that? For cases where I'm ssh'ing into a server with its own tmux session and need to pass data along different panes, or when I'm down to just bare Linux console.

Took one (relatively) small step towards asserting my independence from cloud platforms by self-hosting a git repository in my own house.

What originally sounded to me like a huge, complicated task, actually turned out to be quite simple - if only for a very simple implementation of the protocol. Thanks to this easy guide, I was able to get my Raspberry Pi hosting a few repositories in less than 30min (I spent more because I had to do some debugging to get it up and running).

The final solution is pretty clever, and uses SSH as the backbone for transport and authentication. So if you want to learn more about how the git protocol works and the "innards" of something like GitLab works, the above is definitely a good read.

Anonymity is a hard topic, even for experts, due to the sheer number of moving parts that can interfere with it.

Haha! just found one of the first images I drew after learning how to use GIMP ten years ago after just starting to use Linux.

Internet - Piracy Rocks!

Interesting to see how Free Software really fosters an atmosphere of "learn it, master it, enjoy it." Before, when I used Windows, I had no incentive to learn how to use my computer other than games and browsing. With Linux, I feel that the mindset is (and always has been): "you can do anything here, as long as you're willing to learn."

And learn here is really the key; I have an understanding on what a computer is and how it works (skills which were turned necessary even for my career at one point) that I'd quite frankly never have had I not discovered Free Software.

I'm not sure if anyone made this before, so I decided to just go with it myself: a curated list of alternative frontends to many websites

Probably not complete or comprehensive at this point, but does the job to cover most of the popular websites today, giving browserless alternatives when possible.

"Why do people keep using slack at work? There are so many better alternatives that are free and federating out there."

"I wish we could use Linux in our office. That way, our computers would be so much more efficient and IT incidents would be cut down."

"I hate Office365, the company should've self-hosted Nextcloud so we could collaborate efficiently and with freedom."

All of these are valid arguments, and frankly I've thought of them myself for quite the longest time of my professional career. However, this Linux user-centric view shadows away a very important and often overlooked thing for an IT department: availability of support.

Say what you want, support for Microsoft stuff comes almost built-in for enterprise, and with centralized services, you can always put the blame on them instead of your internal IT organization. If I want to get help setting up my Nextcloud service in my NAS, though, I better hope there are enough motivated people in IRC to help me out.

Am I praising centralized services? Absolutely not. But this area of professional support provision is definitely something that Free Software needs to improve on if it must tackle the enterprise beast. Canonical, Red Hat, etc all noticed this already. Who's missing next?

Here's a good, but brief writeup on why so many IT organizations shy away from Free Software alternatives.

I've been thinking about a sort of "semi-disposable" (think: burner) means of communication can be made using temporary and disposable email addreses such as GuerrillaMail or YOP Mail and a combination of GPG and Tor.

Once anonymous identities are established via Tor, two people with mutually-recognized PGP keys could start exchanging messages over these services, with a (brief) history until they burn these identities (and start over in the future).

Of course it could be done with something like Mastodon DMs or even XMPP, but the "burnable" part of the stack is a little questionable. These email providers, however, would probably gladly throw away everything related to the account once you're done with it (GuerrillaMail at least seems to be Open Source).

Only in crazy times like this would watching a movie illegally (how do you define this anyway???) be equal to committing a murder or assaulting someone in terms of punishment.

The more you use, the more you learn... that's a good Linux metaphor, and a genuine truism. Having switched to Artix Linux, an Arch-based rolling-release distro without the use of systemd, I recently found myself struggling to understand how to start and stop services in it. Turns out that one of the goals of becoming systemd-free is to restore a classic init system a-la BSD, with a start and stop script for such "daemons."

So, if anyone has been having this same problem, here's how you can solve it (with OpenRC):

  1. Install the software you want to run as daemon. Example: tor.
  2. Install its init package. In Artix, this follows package-openrc convention, which, for Tor, would be tor-openrc.
  3. To start the service in a systemctl fashion, run as root: rc-service tor start

And that's about it! It's so great to be able to learn and solve things yourself in Linux!

It's almost 2021 and IT organizations still are not shipping their end-user computers with a password manager.

Look, how about we all just agree that people downright suck at picking passwords and remembering multiple ones? Just pick one strong one that you can remember well and let your computer do rest for you: generating a distinct strong password, assigning a different one to each service you access on the internet, and backing them up so you'll never lose them.

That's exactly what a password manager does, and if everyone uses them, we will never have to implement stupid password policies or worse: rotate passwords every three months.

Permalink 20201201_0453

It really amuses me how some seemingly simple things can spur an enourmous amount of arguments. Take password strength, for instance.

When Randall Munroe posted this famous comic about how correct horse battery staple can be a much stronger password than your l33t_h4xoR666-style passwords, an entire new category of discussions arose, dragging in even people like Bruce Schneier in the mix.

xkcd's "Correct Horse Battery Staple"

The simpler something is, the better it is to use, adapt, and study, and a password policy is no different. People suck at generating random values; let the computer do this for you. And if you need one master password to manage these for you, use Diceware.

What do you use to manage your passwords?

They say "too good an offering, too good to be true." MEGA, an online storage service and spiritual successor to Kim Dotcom's MegaUpload, offers 15GB presumably end-to-end encrypted storage services (it's 35 + 15GB for the first month or so, later it drops to 15 and you have to invite others to get it back).

As usual, without an auditing, there is no way to confirm Dotcom's promises (Free Softwre should make this moot). But thankfully, there's still a chance to guarantee that you won't have to trust him, or any other host as a matter of fact: preventive encryption.

If you PGP-encrypt your data before it gets uploaded, you won't have to ever care about what the host can read. For stuff that changes little or never (images, etc), this is borderline perfect.

Just found out about Tildes.net, a content aggregator that looks similar to Reddit and probably works in a similar way as well. The difference, though, is in the whole ethics of the platform and its operations: see their Philosophy for an example.

I think this is a great step forward for the fediverse in general, as I had not seen a service like this anywhere before. The only downside is that it doesn't seem to federate (yet?) unless it uses the tildeverse ID as credentials.

Great job, Tildeverse!

Although perhaps the RIAA did "win" the case and took down youtube-dl from Github, the wonderful Streisand Effect made a pyrrhic victory out of it. Witness the tens of new repositories that sprung from it, as complete as possible with even commit history, and the hundreds of anonymous copies (like this one in IPFS) that were made following the announcement.

People will not be silenced by corporations, that's for sure. Now we need to work the other side: how do we switch away from a culture that worships big corporations to one where our culture gets made by the people and for the people? That's the key question. And the answer will essentially disrupt any influence the RIAA and MPAA might have on the media.

This copyright madness can't continue. Github does not have a monopoly on youtube-dl source code, and go the RIAA does not have a monopoly on free speech.

If you care the slightest bit about Internet Freedom, please take 10 seconds to run the following command in your terminal:

git clone https://codeberg.org/polarisfm/youtube-dl

Even if you're not going to develop or distribute it, having the source with yourself means that the program will not disappear and it will become much harder to censor. You can take this one step further and redistribute it, either in clearnet or alternative networks, like in IPFS, where it's now available through this hash:

My next step is to become a persistent seeder of all of my works I upload there. To do so, I'll do it like this:

  2. Upload and publish the episode in my instance (diode.zone).
  3. Delete my original file on my computer.
  4. Download my own video through torrent (essentially becoming my own seeder).
  5. Contribute to the persistence of the federation.

It's good to be back to the Fediverse with a new Mastodon account.

Part of me wishes to keep exploring a "side-fediverse," that of the Tildeverse. When I signed up for the town, I didn't originally know that there were so many other tildes around, they form like a real parallel federation by themselves. Previously, the closest thing I had experienced was the Peers community, and it's pretty small by comparison.

I guess it's time to go exploring this weekend too!

Ok, it's finally done. My new Mastodon account is under Fosstodon, and you may follow me there at @kzimmermann@fosstodon.org.

I initially was a little reluctant about using that instance as it has more than 13k members, and didn't want to unbalance the federation by overloading a single server. However, unlike the old Quitters, Fosstodon seems to be doing just fine and has an extensive history dating back from 2017. Also, see Mastodon.social doing just fine with 500k members.
