First post: hello Tildeans!

In fairness, the title question no doubt applies to those on traditional courses/paths too - such is software.

Anyway -- in my experience, reading technical material which is too advanced is without a doubt the most intellectually confusing, emotionally damaging, and personally rewarding part of learning about software development. How about you?

I started basically from scratch last September without any knowledge about programming or Linux except a very brief stint in 2010. I'm a somewhat disorganised person (to say the least), and my learning habits have reflected that: I've followed my nose and impulse, reading pretty much whatever I've felt like. But I've ended up with a presumably ridiculous ratio of hours reading about code vs hours actually coding.

I'm a lazy person, so I'd rather sit and struggle with something I am definitely not ready to understand than go sit in front of a REPL, working from the ABCs til I can do the A-Zs. But the longer I look into things, and the more I play, the more I realise how much coding is like an instrument -- you really do have to just sit down and practice your damn scales! My experiences also support the argument for that 'T-shape' style of mastery (learn one thing very well, then branch). 20-odd Project Euler problems in a week or two has taught me far more than several months half-reading or half-listening to online material.

(Though, I think my 'inverse-T' approach simply has it's own set of trade-offs, rather than being plainly weaker, but that's for another discussion...)

The most ridiculous thing about this field is that there is no end to things you've never heard of: and I hate not having heard of things. My usual style when getting into a new obsession is to read very widely, but it feels like this is at best wasted effort here, if not actively counter-productive. It takes just a few clicks through HackerNews (or say, a read of some of the comments on Systems Programming topics) to find a paragraph that is entirely impenetrable to me. Man, that pisses me off. I think maybe as an ego-defense thing, I've always tried to get a 'gist' of the conversation or topic, but I reckon now this probably just breeds half-formed misunderstandings at best (Alexander Pope, "a little learning is a dangerous thing" etc etc).

Over the past couple months I've made far more visible progress than in any before, and I think a large part of that is learning how to admit when I am completely unable to access some sentences written in English, and how that's totally fine. My path is a lot clearer, and a visceral notion of sub-goals and stages of learning is a really nice thing to have. It's very relaxing to skim a blog post that goes completely over my head and think 'NBD'.

So, what are your experiences? Blocked by hubris/a short attention span like me? Or perhaps the opposite problem - finding you could grasp way more than you gave yourself credit for, after sticking too long with what you already knew? (These questions definitely intersect with things like perfectionism and imposter syndrome.)

I'm really curious to hear how you've dealt with things you feel you 'should' understand -- or how you manage the sheer volume of potentially-useful information out there (RSS, Pocket, something else?). Thanks for reading.

Hi guys,

I often find myself writing small text files for projects, like a bit of documentation or TODOs. I have a proper system in place for larger projects, but would love to be able to scribble down things for larger ones.

As big of a fan of Markdown as I am, I find that it's often inappropriate for these kinds of tasks. For example, I find myself mimicking a task list with multiple-paragraph list items.

What do you guys use? Do you know of any Markdown alternatives that give you a bit more control over the layout?

Thanks!

I hope I’m posting this in the correct place. I’ve been having a disagreement with someone over the abilities of hackers. I kinda hope Deimorz pops in because he wrote automod.

I said that the only way for someone to gain access to a subreddit to make changes is if they steal a moderator’s account password or they are added to the mod team. The person I’m having a disagreement with believes that adding text to the wiki for users to view (like the extensive wiki r/skincareaddiction has) would make it easier for hackers to insert malicious code in order to gain access to the sub. This person also mentioned being able to change the subreddit through browser tools. She insists the sidebar and wiki are potential access points for scripting attacks. Automod just so happens to be enabled which is why I mentioned Deimorz.

I’m not an IT professional. My brothers currently are which helped me learn most of what I know. I’ve supplemented that over the years with whatever info I came across online. What she’s saying sounds like crazy town to me. But since I’m not a hacker, is there a way to use the sidebar or wiki area to hack into a subreddit?

Thanks in advance to anyone who pities me by providing a detailed answer to this thinly veiled request to help me win an internet argument 🙇🏾‍♀️.

Background:
I was deciding what to do since we use Atlassian’s Stride and it will be sunsetted. For us, the options are Teams or Slack. I’m going to give Teams a try since we already pay for it. Someone I know also happens to be a PM there. I texted him “wow, Teams iOS has a 4.7 rating in the App Store!” He said, yes, it’s probably our best client. It made me realize that this is very often the case. The iOS client is often the best client for many services.

Questions:
Do you all find this to be true as well?

If so, why do you think this is? iOS itself? iOS app guidelines? iOS devs are more product minded? Android device fragmentation?

Any and all thoughts appreciated.

note: I am mobile OS agnostic, I use them all (both) regularly.

After seeing the "what OS do you use?" thread earlier, I was wondering what everyone here on ~comp would think of a sort of group demographics survey. I think that it would be super interesting to see the data on things like preferred OS, main programming language, preferred text editor/IDE, device OEM, etc.

Me and my friend arrive at an arbitrary place, we have access to a network from there. Now, we want to share a file and the network connection is all we have. The challenge: make the file go from my device to my friends device in a pure p2p setting. If you know, for sure, that incoming connections are allowed this is very simple but here i want to explore which solutions exist that do not assume this.

Assumptions:

• Same network altough possibly different access points (one might be wired and the other wireless)
• We have no prior knowledge about the network, incoming traffic might be blocked (outgoing isn't for sure)
• No extra machines can aid in the transaction (no hole punching etc)
• Should work reliably for any kind of device that you have free -- as in freedom -- control over. that is PCs, android phones/tablets and macs. most of Apple's other hardware can be excluded because they don't allow for anything anyway.
• hard mode: We are both digitally illiterate

Goal:

• Send a file, p2p, from one party to another.

Me (MSc cs) and my friend (PhD cs) tried to do this last week. And it appears to be among the hardest problems in CS. I would like to discuss this and hear which solutions you might have for this problem.

Edits:

1. this is not an assignment
2. Added some specifics to the assumption set
3. we're looking for practical solutions here.
4. more specs

Right now I dual boot windows 10 and fedora, windows for gaming, fedora for everything else. I'm considering running linux as my only native operating system, and running windows in a virtual machine for gaming. This will be more convenient than restarting my pc every time I want to play a game, and I'll feel better about having windows sandboxed in a VM than running natively on my computer.

To get gaming performance out of a virtual machine, I'm planning to have two gpus. One for linux to use, and one reserved exclusively for the virtual machine.

Have any of you set up a computer like this before? What was your experience like? How was the performance?

Trying to get a sense on how the networking would go down?

If I had one public IP address and say 4 Docker containers on the host, how would the SSH connections work? Would I have to reserve ports for each container?

I'm primarily a non-programmer these days, but have a fairly extensive background in statistical analysis - seeking recommendations for best/cheapest/easiest-to-learn data visualization tools. I have access to PowerBI and Tableau through work, but any other recommendations are welcome. You can take the SQL-family relational database query skills for granted, but not necessarily noSQL, Hadoop or the other popular big data sources.

What domain registrar do you suggest? I have several domains with GoDaddy. I have them there because one of them is a .it domain, and several other registrars didn't offer them at the time. So I kept everything at GD to have it all in one place. And for the longest time, they were giving me great deals, but not so much anymore.

They send me a lot of coupons and try to sell me on the domain club here and there. They sent me a coupon for 20% off renewals. I thought great, but when I checked my control panel the prices of renewing had doubled. GD is really overcharging at this point. I plan to let several domains just lapse and keep the ones worth money and the ones I use personally. Which makes this even more of an ideal time to switch.

I was hoping Name Silo finally offered .it, but they don't. At this point I have been waiting several years for them to offer .it support, and they keep saying check back in 6 months. So I'll just bite the bullet and leave my .it and .me at GD and move everything else out if they end up being the best deal. I'd like the keep them together because I use those two for email, and I'd like them in one place for management ease.

Thanks

As someone who is relatively removed from the programming world (I do basic Python scripting and not much else), I'm curious to see an argument opposing what I perceive as the majority viewpoint. Those against the acquisition have cited examples of Microsoft "ruining" services such as Skype and Minecraft.

Okay, I know the obvious answer is the history of the files. But how can I, from the command line, really understand what is hiding inside that .git directory?

Today I was doing one of my periodic disk space audits, trying to figure out where my usage goes. This comes from having a 64GB drive mounted as /home on my Linux laptop. I found some 15G of old video files to delete today, so I'm no longer as pressed for space. But my interest was piqued by one thing I have downloaded from Github that is ~120 megs for a very simple program. Poking around further I find that most of that usage is a single file:

$ ls -lh withExEditorHost/.git/objects/pack/pack-df07816cd15fb091439112029c28ebc366501652.pack
-r--r--r-- 1 elijah elijah 102M Mar 14 23:28 withExEditorHost/.git/objects/pack/pack-df07816cd15fb091439112029c28ebc366501652.pack

$

Is there a unzip or tar xzf equivalent for Git pack files? Naive usage of git unpack-file is only generating errors for me.

I have to do an assignment for university soon-ish, and it requires Angular. I'm not very fond of that framework specifically, but I would be interested in making it more interesting as a learning project. I've also recently discovered PureScript, which I have no experience with right now.

Searching online, I've purescript-angular, which hasn't been updated in years. I also couldn't find much else. Of course, I may be missing something simple (for instance, it's actually supported by default in Angular these days), so I wanted to ask if any of you know if this is possible, and if so, how?

Hey there!

I'm planning on going full linux again (last time was 5-6 years ago). The only problem is: i've lost track of the community and especially what hardware is currently best to run, especially tech that was really giving me headaches back then (GPU - remember the omega drivers?).

But searching for linux compatible laptops without purchasing a machine from some dedicated vendor is quite hard.

Any recommendations?

I'm going to be flashing a custom ROM on my Nexus 5X device, and I was just curious if I'm understanding all the components involved. I currently have CopperheadOS on my device, but that ROM may be dead based on current events. I'm not switching because of this news, but mainly because I just want to try something else for the hell of it. I think I'm going to make the switch to Lineage, but there are way more options involved versus flashing CopperheadOS.

It seems the main components to consider when flashing are the following:

• The ROM itself (CopperheadOS, Lineage, PureNexus, etc.)
• The custom recovery (TWRP, etc.)
• The kernel (ElementalX, Franco, etc.)
• root (magisk, etc.)
• Play Services (OpenGApps, etc.)

CopperheadOS was kind of it's own package, so I didn't have to consider all of these other options.

My understanding is the minimum decisions I need to make if I want a custom ROM, is picking the ROM itself, and a custom recovery. In my case I'm going for LineageOS and TWRP.

Choosing a custom kernel seems to be optional. I think I might go with Franco on this one based on the little research I've done. But to flash a custom kernel, I think I need root, right? So now I'll need to get root access which requires another tool. I was going to go with Magisk based on not much. Just seems to be common. So that's 4 main things there. The ROM (LineageOS), the recovery (TWRP), the kernel (Franco), and root (Magisk). I personally don't want any Google services on my device, so I'm fine with skipping that part. I currently don't have any installed, and I'm doing fine without them.

So does my view on this seem correct? Are all the things I mentioned necessary for what I want to do? If I want LineageOS then I need a custom recovery right? If I want a custom kernel, then I need root which requires a separate tool, right? Just making sure I'm not doing more than I need to if I decided to go through with this. As a side convo, please recommend whatever ROMs, kernels, or root tools that you want. I have a Nexus 5X, and I'm hoping it doesn't bootloop after I'm done doing all this flashing =)

Hey all,
I've been studying Common Lisp recently, and as far as I can see, this is a pretty capable, mature language. Moreover, Lisp has been around since the 60s and it doesn't see much usage (as far as I'm aware) outside of Emacs Lisp and AutoLISP. What gives?

I've been using Solus for years now as my main driver, but I think I may be switching to Arch soon. Or at least, start using Arch on my laptop, and keep Solus on my desktop. The main reason I wanna give Arch a try is because of how minimal it can be. I don't need a lot of applications, and I like to have the least amount of software installed on my machine as I can. Plus, distro-hopping is a disease, and it's time I try something new, haha.

So, I was just curious what DE people are using with Arch. Ideally I want something very minimal, but not too ugly. I liked using Budgie with Solus, so I may very well just use Budgie with my Arch install, but I thought I would see if anyone has any recommendations first! Thanks!

By coding headphones I mean with active noise cancellation, to be focused on your work. However I'd like to have it more universal since i do play videogames in my freetime, so with a microphone would be best - Or should i have 2 sets for both activities?

Something below 100€ would be nice (naive yes, but I aint got much).

I looked at the Mixcder e7 on Amazon, which looked promising. Thoughts?

There seems to be a solid community of Linux people growing here, so thought I might try asking...

I'm building a head unit for my car, using a Raspberry Pi to a 7" (and eventually 10-14") touch screen.

I'd like to have a fast-booting Linux distro with tiling windows that lets me set up a config file to launch a bunch of programs that are tiled perfectly edge to edge, with minimal border (a 1px line us OK), minimal header (just the name of the program? or none at all maybe), and have them all locked in place so I can't accidentally drag one or resize one when touching audio controls, for example.

The idea is to have a few windows, such as an audio player, a GPS map, 2 dash cam feeds, and an OBDII style sensor readouts, all on screen at the same time, each sized differently.

I've got each individual program working fine on Raspbian right now, but no idea how to go about the tiling-on-boot, locking them in place, etc.

Can I do it with Raspbian with some specific window manager? or do I need a different distro?

Thanks in advance.
