Hey y’all. Recently picked up a Cyberpower prebuilt. Looking to install a Linux distro on it for gaming. Currently have Ubuntu on my laptop, so I’m not a total noob, but my experience is still low. Not a big fan of having to use the terminal. Any distros y’all would recommend? Am leaning toward Pop_OS or SteamOS.

I'm starting grad school in neuroscience/biomedical engineering soon, and one of my most dreaded parts of it is inevitably having to develop Matlab code. I understand why people use it -- it's arguably best in class at a lot of engineering tasks, and the matrix-first approach of the language makes it very fast to prototype things if you think like a mathematician/engineer.

However, the language also seems to actively discourage good software practices, and many frequently used scientific projects have atrocious code. Think python dependency management is bad? How about NO DEPENDENCY MANAGEMENT? Yes, that's right, the way you share code in matlab is by importing collections of loose files from github/matlab file exchange. The Matlab neuroimaging code that I have worked has also frequently abused the workspace to share state implicitly between scripts, which makes the code virtually incomprehensible. Instead of using packages to create namespaces, common practice is give function names a prefix and import them into the global namespace.

I know there's multiple large companies that rely on Matlab for their products, so it must be doable; I just haven't seen it for myself yet.

Do you guys have any experience developing in Matlab, and if so, are there any good resources to learn how to build robust software in it? What are some open source projects that have good Matlab code?

I cannot push nor pull to/from my local repo to/from my remote. I get the message "Your branch and 'origin/main' have diverged", etc.

I will be able to fix it, I'm already in the process of refreshing my memory on how to rebase this cleanly.

But ... I am the only person working on this. I have only one local and one central/remote repository. And I never made a branch.

It's just me, working on one computer, right here ... make a few commits locally, then push 'em ... make a few commits locally, then push 'em. That is my entire workflow.

How in the hell did I end up with "my branch" (???) and the origin/main branch being in conflict with each other?

Any Git gurus care to take a stab at this?

Thanks in advance.

Edit, more info:

I am guessing here, but for awhile I was working in a VM on my local machine ... but Android SDK is too much of a resource hog, so I committed and pushed everything on the VM, shut it down, and then pulled latest down to my actual machine ... or at least, that's how I remember it.

My working theory is that, somehow, I screwed up that "switching between machines" process, although, so far, no clue as to how/why I did.

Theory #2 is that Android SDK did something sneaky/stupid behind the scenes -- my last several commits have been done through the Android Studio IDE, not directly in the terminal.

Last Edit:

D'oh!

Found it. I made a couple of "quick changes" to the project's README.md file directly in the remote forge, and that's what screwed me up.

The history of the web is littered with with many a dead image/video hosting service. Echos of their existence plague older forums in the form of broken links and images. It seems like they all follow the same path, starting up as the new "simple" service that just hosts images, no fuss. But then as interest grows, so do costs, and the service owners have to scramble to monetize. Generally this is done by stuffing the place full of ads until everyone leaves. Alternatively the owners are stubborn and stick to their guns, until they inevitably have to shut down due to drowning in costs. When they do shut down, millions of assets are lost and the graveyard of broken images across the web grows some more.

https://gfycat.com/ is the latest notable victim of this.

With all the recent social media turmoil, there as been lots of exploration of alternative sites, and all of them have to overcome the problem of hosting media in one way or another.

Tildes obviously does this by avoiding it entirely which, while a very effective solution, is just handballing the problem elsewhere. Users will still want to post images and videos but they will just have to find alternative hosts. Over time those hosts will die and Tildes posts will be filled with dead links.

Mastodon has similar problems,the biggest cost of hosting a mastodon instance is the storage and bandwidth required to facilitate media posts. And there's a real danger of an instance incurring high costs if a particular post becomes popular and is hotlinked on a big centralised social media site.

It seems like a really tricky problem to solve, something peer-to-peer could sort of solve the costs created by traffic peaks but has problems when there is many small files viewed by few individuals each.

Are there any other solutions out there? Web3, IPFS? Or is it just not that much of a problem, do we accept that media on the web is ephemeral and will be lost after a while?

This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?

Hey there! Any web developers/designers out there that have resources on creating websites that are fully accessible? I am getting back into web development after a decade away and want to learn the correct way. Thanks for any tips!

Self-hosting has been a rabbit hole of wonder that I've explored and delved into over these past few months. I'm curious to hear what others use it for, what apps they love, and their rationale for doing so?

I'll go first.

First, in terms of rationale, this is a wonderful article that I think is worth checking out that encapsulates much my of ethos about pursuing self-hosting.

https://kylechayka.substack.com/p/essay-the-digital-death-of-collecting

The TL;DR is that we no longer have control over the things that we 'own' digitally for these massive cloud companies. For instance the songs / artists you listen to on Spotify may suddenly and unexpectedly become unavailable, certain things (most recently podcasts) may be forced upon you in unpleasant ways. Having complete control of your digital data is a very liberating feeling.

In terms of apps:

Hyperbackup - I use a synology NAS, so hyperbackup has been wonderful and use both external HD's and a cloud interface to create encrypted backups of everything which gives me peace of mind.

Plex - One of my most used apps, being able to stream anything remotely has been a dream. Plexamp has given me back control of my music library in a way I never thought I would have.

Tautulli - Great for more informatics on my plex usage

Calibre / Calibreweb - Phenomenal for keeping track of my book collections

PiHole - Ads be gone!

*Arr apps - Specifically Sonarr/Prowlarr/Radarr, really like Overseerr for an interface tying everything together

Daily Notes - A clean interface for keeping regular notes

Some things that I'm not currently self-hosting but would love to hear if others are using alternatives...

Instapaper - I know there are a few similar FOSS apps out there but haven't found one as convenient and well laid out

TickTick - To do app, but similarly haven't found a FOSS alternative that was as robust and nice to use

OneNote

Back in the day I remember setting up squirrelmail + qmail to host my own email as well as for others. And then I got that coveted gmail invite and never really looked back.

I've started to get into the mindset of erasing my digital trail, at least for my personal activities, and email seems to be the main one that I need to figure out.

The idea of setting up my own email solution came up again because I wonder how transparent / private services like protonmail and mailbox.org really are.

Any suggestions or insight would be appreciated. Squirrelmail seems to be now defunct, and I am pretty sure the world has changed enough that residential ISPs don't allow running of servers at home anymore. I guess I could setup something on AWS if I had to.

So, I'm using Arch i3wm. I have multiple copies of my /home/username (I am the sole user), and I have a "Spare" drive with media, games, and other goodies, some of which are also stored on partitions on the m.2 in question, but they have backups.

And the reason I ask this question is because while I've had my m.2 fail at the end of '21 (I didn't even know that was a thing, but it barely lasted a year, and things are acting shoddy now... though the original failed without a warning), I just bought a second m.2 for my games. I guess I could swap most of the whole thing over, but I know the boot partition is easier just rebuilt from scratch... which I had to do last week.

Ultimately, what's making me suspicious is when I upgraded to the new drive and unplugged all my non-m.2 satas, I also added some memory and a new power supply. But then after the upgrade (Monday of last week, so the 5th), the system wouldn't boot up. I used a usb to troubleshoot and my /boot partition was apparently no gouda. I redid that, and everything was fine... until this week. Then my new Games partition (basically the new drive) failed fsck and it got stuck in a boot loop on Tuesday. I could boot emergency to root, but not skip the fsck and keep the Games disk auto mounted (I know I changed something to randomize fsck on bootup, but that's something I'm still kinda looking into how I managed...), so I just removed it from my fstab and it booted fine. For two times. I just manually mounted the drive, all was great, then my SO sent me a screenshot today while I was at work stating that my / partition (on the older m.2) apparently rebooted because it bypassed my screen lock, and was stating EXT4-fs error, reading directory lblock:0 and whatnot.

So, that's my history on what's going on, and if anyone can offer any advice [mostly] on the backup stuff, though as I said, /home and the important tangible stuff is saved, but if you also have any input on something more than I suspect the drive is failing (since the /boot partition and now the / partition are crapping out), please feel free to share.

(Also, thanks for letting me in. This is what I'd typically post on reddit and probably have to repost 10 times depending on the sub to get the right keywords and tags and yes, I already searched the internet but my search will not match yours... sigh)

While pondering an off-grid microcontroller project, I got to wondering: A light sensor can obviously detect day vs night. So it could be used as a very cheap way to set a device's clock - but how accurately? To within an hour? A few minutes? How would you do it?

Questions that arose from this include:

• Should it detect dawn/dusk (light <-> dark transition), or noon/midnight (brighest/darkest time) ?
• How do dawn/dusk times relate to clock time? Does it depend on lat/long?
• If using dawn/dusk, what light level threshold to use?
• The same threshold for dawn & dusk, or different ones?
• Better to detect a darker threshold (start of dawn, end of dusk) or a lighter one?
• Some days will be lighter/darker than others, so how to manage averaging of times?
• How accurate could it be made?

My naïve first stab at this would be: Pick a light threshold. Record the dawn/dusk times according to that threshold. Average them, call that "noon", and gradually tweak the clock time over several days to bring it into line with the sensed/calculated "noon" - but a searching for graphs of sunrise/sunset times quickly showed that the midpoint of sunrise & sunset is not noon.

Googling threw up lots of results for sensor lights combining a clock and a photocell, but I couldn't find anything about using the photocell to set the clock. So does anyone know if this has been tried before? Is it a non-starter for some reason?

Edit:

Perhaps it's worth sharing the project I had in mind, which is a rain alarm so I can rush out and get the washing in from the line when it starts to rain. I was thinking how annoying it would be if I left it switched on and it rained in the middle of the night and the alarm woke me up. So I decided should automatically avoid triggering during the sleeping hours of night (say 10pm to 8am). My first thought was a photocell so it wouldn't trigger when it's dark. Then I remembered that it gets light at 3am at the moment, which wouldn't work. So it needs a clock. How to set the clock:

• Manually - Needs a user interface with buttons and a display. Seems overkill just for a clock.
• Serial port - Clunky to plug a laptop in just to set the clock.
• WiFi - Needs a username and password or WPS, and an ESP32 or similar - again seems overkill just to get the time.
• GPS - also overkill and expensive.

Hey,

I use Windows 10 and Arch in a dual boot configuration.

I use both of them for software development and want a shared partition to store all the projects.
Unfortunately, it's not as easy as I had thought.

Initially, I tried NTFS as the Linux support seemed fine. I tried both, ntfs-3g and the kernel implementation.
Besides the issue that hibernate could lock the drive - which you can disable - it periodically caused problems during compilation and other stages.

Especially Rust based projects have thrown weird errors during builds, but I also had this on certain Go projects as well.
It sometimes felt like, that the NTFS driver returned the wrong files when the compiler asked for them. Unmet dependencies, missing files, etc. Usually, when the project is huge.

In certain scenarios symbolic links didn't work and permissions were not set correctly - which you can fix by adding some args to the fstab mount - never got it really stable though.

I then tried to format to Ext4, and all issues were instantly gone on the Linux side.

Fortunately, there are tools such as Linux FileSystem from Paragon which promise to make it work (I even bought a proper license) - and it did for a while, until it didn't.

I once copied a bigger folder that included a bigger node_modules folder and during copy, files were missing, corrupted, the copy process hung - then crashed.

I was so desperate that I even tried out FAT32, but I quickly found out that it doesn't support symbolic links at all, and therefore breaks Git and other tools depending on it.

Is it still so hard in 2023 to have a shared partition between two OS? Has anyone made better experiences?
I really don't want to split the partitions as I sometimes work on the same project on different OSes.

Thanks in advance!

I am currently going through the official Rust book and have gone through some of the Rustlings exercises. Both resources have been excellent so far.

What resources have you enjoyed?

Additionally, is there anything about Rust that particularly caught you out when transitioning from other languages?

How does Mullvad removing port forwarding affect an Unraid setup using deluge-vpn container?

I don’t access my server from outside my network and just use a basic binhex deluge-vpn docker setup. Any issues I’ll have here?

Currently out of town and won’t be back until after this change happens tomorrow. Curious what to expect when I'm back home.

Hi
Android Mozilla browsers with access to about:config.
Examples are...
Firefox Beta
and
Firefox Nightly

Back in the day there were lots of config tweaks for PC Firefox.
But there's not much config information about Android Firefox.

I found these two posts on Reddit.
https://www.reddit.com/r/firefox/comments/11shvus/fixing_performance_problems_in_firefox_on_android/

https://www.reddit.com/r/browsers/comments/1278zp5/improving_performance_in_firefox_android_part_ii/

Does anybody here have other about:config suggestions?

Been lurking for a week on tildes now and I am really glad this place exists. The crow here is exactly what I have been missing on Reddit for a while now.

Having said that, the whole Reddit situation has some-what motivated me to get the balls rolling on an idea that I have had for a while and I am looking for advice on the same.

I have often heard this phrase "Learn programming by building" but whenever I dive in to the resources, I fall flat due to the information overload and the general abstractness that the field has (I appreciate abstractness but here it demotivates me) and I have never found a proper resource that I could follow to actually build something instead of just blindly following tutorials and playing with them.

So, my question is how do I translate "learn by building a project" into a practical framework.

I know of 100 days of swift and I really like that approach however I don't think I want to start with swift or build an iOS app right now.

For most of my life, I've been a hobbyist programmer. From Qbasic to Python and JavaScript. I've always wanted to create an Android app, really just for me, just to do it. It's a bucket list thing.

Can you give me a book or a website guide that is up to date and complete but not 100,000 pages long that could help me get it done? A book would be preferred! I just want to cross this off my list!

Lox is a toy programming language that is designed in Java and C at craftinginterpreters.com.

My challenge to you is: given the constraints of the Lox language, what are some creative or advanced programs you can create?

This page provides a rundown of the design of Lox.

To kick it off, here's a simple function that estimates the value of pi:

fun estimatePi(rounds) {
	var pi = 0;
	var alt = 1;
	for (var i = 0; i < rounds; i = i + 1) {
		pi = pi + alt * 4/(2 * i + 1);
		alt = -alt;
	}
	return pi;
}

print "The value of pi is:";
print getPi(100000);

I have to preface this question with a disclaimer that I am an eager learner of Linux and servers in general, but I'm still a beginner and often run into roadblocks.

Current setup:

• Raspberry Pi 3 with Adguard Home acting as primary DNS
• unRAID server with Adguard Home acting as secondary DNS
• About a dozen other containers running on same server
• DHCP is handled by my router

Goal:

• provide local DNS names for the containers running in unRAID so I don't have to enter IP:Port (e.g, calibre.local) which also has the side benefit saving the various username/password combos into Bitwarden with an actual domain attached to it instead of 14 occurrences of 192.168.x.x

Additional info:

I had PiHole running on the Pi before as the primary and only DNS previously. And I seem to recall you could put IP:Port as a custom DNS and have it resolve. AGH does have a feature for DNS Rewrites but it does not allow for port numbers, IPs only. I switched to AGH because it seems to be more effective at blocking ads, which is likely more a function of the provided DNS blocklists out of the box as opposed to what I was doing in Pihole. I would prefer to stick with AGH for adblocking/DNS if possible.

I looked into just modifying host files on the main computers I touch these apps from, but again, can't include port. What is a good solution for this? Preferably something approachable for a newb like me.

You could use any SQL database to create a few tables, insert some data, and do queries, while ignoring anything vendor-specific. But Postgres has a lot of other features and many extensions. What do you recommend checking out beyond the basics?

I've used a lot of databases, but it's been many years, so I assume things have changed quite a bit. I skimmed a few PostgreSQL release notes and learned that there's now a MERGE statement that looks pretty handy. (It's standard SQL.) And from Neon's list of supported extensions, the plv8 extension caught my eye. It would let me write stored procedures in JavaScript. Does anyone use that? Do you use stored procedures at all?

I wonder what Tildes uses?

(To keep discussion organized, please write about one feature per top-level comment.)

Hey folks, looking for recommendations. What's your go to word processor on Ubuntu? (EDIT: For regular writing, not a text editor for coding.) I haven't been the biggest fan of Libre office tbh (please don't hate me...) There were just several bugs in Writer that made it unusable for me. I'm curious about alternatives. I read that WPS office is on ubuntu, but I've always found it to run kind of slow (however, my experience was on Windows.).

I don't need a lot of fancy utilities, but would enjoy something a little more beautiful than notepad++ :) My biggest concern is just that it's a stable software. I'm OK with glitches or UI bugs, just nothing that's going to crash and burn and corrupt my work. (I mention this because there are several newer word processors made by single developers, and I'm a little weary to use them because I don't genuinely know how stable the software is.) I'm also not a fan of software that saves in some special format where you rely on that software to open it (or have to go through hoops to convert it.)

Any recommends?

EDIT: I'm new to Ubuntu, in case it makes a difference.

Pretty much, the title.

I have been coding professionally for over 2 decades, been using Git for almost as long ... and to this day, it still feels alien and uncomfortable to use. I keep feeling like I am relearning it all over again. I would really like to find some kind of different resource that helps me to make Git "stick" in my brain, and become more intuitive. Maybe that's just not possible, but I keep hoping.

Meanwhile, my roommate is just starting her journey into programming, and her class just started teaching Git ... and I'm eavesdropping a bit, and they're teaching it okay, but I'm sure there are better tutorials out there for a newcomer.

I am aware of -- and currently reading my way through -- both this recent tildes post and the various tutorials mentioned in it. But I am looking for other recommendations, as well ... and I bet I'm not the only one.

Thanx in advance.
