learning maths from scratch a good idea?
Main Post:
I'm a 24 year old, computer science student at university in the UK (about to start second year).
Growing up, I didn't study at all and wasn't that great at mathematics.
So I've been learning from the absolute scratch using KhanAcademy (kindergarten level maths)... and often times I think to myself, "am I wasting my time doing this?"
I want to become a well rounded software developer with no current lean to any specific type. I'm leaning towards learning up to high school level mathematics/A-Level and feel like that will help improve my problem solving skills and it's quite transferrable to programming.
So my question is, is what I'm doing a good idea?
Top Comment: I think it's worth it but skip ahead aggressively using khan academy's placement quizzes to land on your first gap. For CS the highest return is algebra and functions, exponents and logarithms, discrete topics such as sets and counting, probability and statistics, with just enough calculus to read limits and derivatives, and you will retain it best by doing a few problems daily and applying ideas in tiny programs. If you want structure then my advice is to plug GCSE gaps then work towards A level Core using Khan and 3Blue1Brown, and treat the time as an investment in future speed and confidence.
First Guitar from Scratch!
Main Post:
My first guitar built entirely from scratch! I learned so much from this experience like, don’t make a Gibson style guitar for your first build, and don’t use one of the toughest woods for something you’ll have to spend hours working on 😂

$0 start from scratch Vintage realism roleplay: Update 1
Main Post:
Well update 1 is here.
So far so good, progress hasn't been easy, but its still progress.
After grinding over $70k in contracts, I secured myself a niece parcel of land tucked away off the main road, right on the water. All I have is a grass field and a small patch of dirt, but I have made it my home with just a canvass tent for now.
Along the way, a nice JD 3010 popped up in the sale section for less than half proce with 10hrs on it. It needs a service and a repaint, and I couldn't afford any upgrades, but they will come soon. It has been great so far.
Wanting to put my land to use, I picked up a vintage HL 180 Avare mower, and a simple old fashioned Lizard windrower and tedder and got to work cutting and turning my grass. Everything worked great and it was nice working at a leisurely pace with the old fashioned gear.
Finally, I put the hand baler to work and hand made 63 hay bales, 600L each. Ill need to save up for a storage area and that should keep my livestock fed when I can eventually afford them.
I am left with a few hundred euro so will need to turn out a few more contracts before I can start generating reliable income for myself, but we are headed in the right direction.
Loving the challenge so far.
Top Comment: As someone who regularly thinks these mega hard play through's are a good idea, but loses interested after the first month, you sir have the patience of a saint! Looking forward to regularl updates.
$0 start from scratch Vintage realism roleplay: Update 3
Main Post:
Well a lot has happened since last update. First up, my cabin finished building, its not much, but its better than a tent.
The left over lumber sold for a very tidy profit which allowed me to expand operations. I now have 2 medium open air gardens, growing Peas and Lettuce with Seeds and Fertiliser for boosted output.
Selling about 50 pallets a month is a nightmare without autoload, but thats the rules I set for myself.
I have completed my goat pen with 40 goats, who supply enough milk to make about $4k worth of goat cheese a month in the small dairy I built, it is going to take a long time to pay off. They will take about 200 years to eat all the Hay bales I made in the first day on the farm.
I am still selling my vegetables and milk/ cheese at a small market stall but I will build a bigger scale store to suit the output for more realism in the next update.
For my last source of income, I built myself a Silage Shed, it was $75k but will be a good long term investment. With the triple mower set up I can mow the field super quick, and the Silage Spikes set up on the 3010 allow me to pick up and dump the grass without needing a forage wagon. It will pay itself off when I expand into other fields to get grass and silage from in the future. It is handy that it can dump into a truck or trailer to be sold once fermented from grass to silage.
Lastly, I gave the 3010 the love it deserves after all its hard work. Repaired, repainted, washed, a new canopy, and an engine upgrade to the 3020, with a whopping increase of +10hp for 68hp total. It has a nice old shed to keep it sheltered, and a small workshop so it isn't neglected any more.
This is about as big as this tractor can go, and as much as I can really do with this lot. Time to call stage 1 finished and work out where to go next for bigger and better farming in this challenge.
Top Comment: Sweet, nice to see the 3010 getting some much needed love. That little shack is pretty cool!
Do you like to use blueprints or start from scratch on every playthrough?
Main Post:
I personally don't bother making or using blueprints for the early stages whenever I start a new playthrough. Once I get construction bots, I'll only use blueprints for copying designs I've made by hand in my current save. I know this is probably drastically slowing me down, but I feel more engaged when I'm placing stuff by hand and having to resolve a problem I already addressed in an old save.
I'll only use premade blueprints for things like balancers or space platforms (because I hated doing them by hand, manually building them with limited design constraints and resources was not fun for me).
How do you like to utilize blueprints, if at all? Do you only use ones you created yourself, or do you use ones made by others?
Top Comment: I copy belt balancers but I make new set ups for each sub factory
Someone left a deep scratch with a key on my new car

Same as title - people do lack civic sense. Should I let it be or get the panels replaced?
Top Comment: Someone did this to my car too Forget about it. Nothing we can do
$0 start from scratch vintage realism roleplay: Update 2
Main Post:
Well, after a medical emergency that consumed my last 2 nights, I'm back home with a quick update on my farm.
Looking out over my freshly cut grass and collection of hay bales, I started to plan the next stage of my operation. I needed to start making money on my own. I figured out which direction I wanted to go in, painfully worked my way through another $25k worth of contracts and got to work setting myself up for financial independence.
The dirt section with trees in the middle of my plot, housing my tent and equipment, was the easiest way to utilise land with losing any of my grass field. The added bonus of some valuable lumber convinced me to start there. I set up a sawmill and felled all the trees into it for production. I had to sell my tent to clear the way and decided this was a good time to upgrade my residence, I've worked hard enough to upgrade from a tent.
True to the vintage realism roleplay challenge, rather than buying a house, I placed a small constructable cabin, with materials to be supplied by my own sawmill. I set the sawmill to produce beams, planks and long planks and let it do its thing.
Next up I built an outdoor garden by the river. I picked up a very vintage wooden tanker trailer to supply it, and filled it in the nearby river. The poor 3010 was struggling with the weight and could only manage a partial fill of 1200L before it reached max weight so it took a lot of trips to get plenty of water. I set the garden to grow lettuce and went and rested in the new tent I was using until my cabin was built.
The next day I had pallets of lumber and lettuce ready, but realised I didnt have a way to move them. I picked up a 3 point pallet jack and moved enough lumber to build my cabin, with the rest to be sold at the nearby store.
Wanting to stay like a real roleplay, rather than selling my lettuce in town, I set up a market stall to sell on my farm instead, direct to consumer.
Income is finally trickling in, my cabin is being built and I am already thinking of the next step for upscaling which should not be far off at all. As you can see in the last pic, the 3010 is looking worse for wear, it will be getting some love for sure!
So far I have stayed all vintage, and stuck to my own challenge rules and it feels amazing. Thanks for following along.

My bf made me this bad boy from scratch. Please praise him
Main Post:
My bf just did it today for me. Still not fully cleaned, etc, I'll do it tomorrow when I have free time. Please praise him, I think it looks great.
Top Comment: You go, Boy. Nice job. Customizing small, “daily” spaces like this is one of the best ways to improve your skills and enjoy the fruits of your labor. Keep it up. 🚀
Is this scratch only cosmetic?

Question while configuring C1161X from scratch
Main Post:
Hey guys,
I'm trying to configure a new Cisco C1161X but I'm having connectivity issues. I have three interfaces I'm working with:
GI0/0/0
ip address x.x.248.113 255.255.255.248
negotiation auto
GI0/1/0
switchport access vlan100
switchport mode access
spanning-tree portfast
interface Vlan100
ip address x.x.163.1 255.255.255.0
ip route 0.0.0.0 0.0.0.0 GI0/0/0
And I have IP routing enabled.
I have a machine plugged int GI0/1/0 and it can ping Vlan100 but it cannot ping GI0/0/0. Everything I've been seeing online just tells you to ip routing so I think I may just be missing something obvious. I've also tried without switchport mode and spanning-tree on gi0/1/0. Any ideas?
Top Comment: Does Gi0/0/0 have a link up? show interface and show route output be useful.
If you have 0 programming experience, I strongly recommend starting with Scratch
Main Post:
I just finished making a game on Scratch (https://scratch.mit.edu/) and learned a lot very quickly. It is intended for kids/teens, but I'd recommend spending a couple of days with it to anyone. You'll learn how to approach programming problems and all the basics without worrying about the syntax. It's so much better than starting with tutorials that just make you copy-paste their code, as you learn by doing and looking at other people's projects to figure things out. My project's "code" is not perfect and I'm probably not going to spend more time with it, but it definitely got me motivated to continue learning.
If anyone's curious, here's the game that I made. It took 3 days with little programming experience. Working with aspects of the game loop, sprites, sounds, animation, bug-testing, etc really helped me understand the bigger picture.
https://scratch.mit.edu/projects/287503779/
Top Comment: Scratch gets a lot of hate with semi-experienced programmers (the kind to browse this sub) because of its simplicity, but it's actually really good. It teaches you basic programming concepts without all of the complexity of other programming languages. I remember back in school, some of the students in my computer science classes didn't understand the basic concepts of programming: variables, loops, functions, etc. and programming is 90% logic and problem-solving. You can't teach programming by teaching the syntax of a language, you have to teach logic. If you know one language, figuring out another is going to be easy because most of the things are the same, the only difference is the syntax.
Am I dumb for not even being able to understand Scratch?
Main Post:
I've begun learning under HarvardCS50, and one of the first projects they want us to partake in is using Scratch to code something simple. My idea was simple. I'd make a game that was similar to pong, but with only one paddle. You'd have to bounce a ball on the paddle for 5 rounds, with the number of balls increasing by one each time. Creating a bounce function was simple enough, and I got it to work without much effort.
To actually make it a difficult game, I wanted the balls to arc randomly, picking a specific number to curve by on each bounce. My first attempt made the ball vibrate in the air: I understood why, my while loop ("forever loop" in Scratch terminology) was changing the x value randomly every single time it wasn't touching the paddle, so it didn't quite look like an arc. I tried a couple of other things, but a lot of the time, Scratch wouldn't even do anything with the code.
See, I've coded before, but my I struggled with compsci knowledge, and I thought it was gonna be an easy introduction into coding logic, but it's only lowered my confidence with trying to code, if I can't even get this to work. On a similar note, I can't even complete some of the simpler problems on Leetcode. How do I get problems that are actually suitable to my skill level? I feel like my problem solving skills are trash, but how can I improve them?
Top Comment: By tackling problems you don't have the answers to. It's not about consuming answers and how to, it's getting the mental tool kit to keep trying and finding(researching) different ways to tackle the problem. Try to articulate what you want to do and ask the google questions that lead to your answers or at least different things to try
Have you guys ever seen a good game made in scratch?
Main Post:
MIT's Scratch is often the tool that people associate with like junior high tech class. But I feel like it has some serious potential if used correctly. Have you guys ever seen a good, quality, Scratch game? This is all subjective or course.
Top Comment: I think Scratch is great, and I'd thoroughly encourage people to get their kids to mess around with it. But it's not a good choice for making anything of releasable quality. I'm sure if you unleashed a talented individual on it, then they could make something pretty awesome pretty quickly, but they'd be making it despite Scratch rather than because of it.

Reddit brownies

Made them last night. Came out amazing! Recipe from Moonjelly 33!
Top Comment: I did reduce the sugar and omitted the espresso powder as my kids will be eating them but everything else was per the instructions. Also- I baked in a 9x9 square pan and I felt it was a bit too big- Some of the edge pieces were thinner. Are you all doubling the recipe to fit a 9x13?

Matching self-learners into tight squads to ship career-ready LLM projects: the speed and progress of Reddit folks in 5 days just amazed me.
Main Post:
Nine days ago I posted this, and 4 days later the first Reddit squads kicked off. The flood of new people and squads has been overwhelming, but seeing their actual progress has kept me going.
- Mason hit L1 in 4 days, then wrote a full breakdown (Python API → bytecode → Aten → VRAM).
- Mark hit L1 in just over a day, and even delivered a SynthLang prompt for the squad. He’s attacking L2 now with a 3-day goal that he defined.
- Tenshi refreshed his highschool math such as algebra and geometry in L0, and now just finished L1. He’s invested more time in the inner workings of OS.
Lot more folks also done L0, L1 and are putting their experiences, strategies in r/mentiforce.
When I look back at the first wave of Reddit squads, a few clear patterns stand out.
- When the interface allows us to ask anything anywhere, many folks brought up topics far deeper than I could have anticipated.
- The criteria of understanding rises sharply when people apply our strategy to construct their own language, rather than passively consuming AI-generated output.
- Top-level execution isn’t just encouraged here, it’s engineered into the system. And it works.
These aren’t just lucky breaks. They’re the kind of projects you’d normally see in top labs or AI companies, but they’re happening here with self-learners, inside a system built for fast understanding and execution.
Here’s how it works:
- Follow a layered roadmap that locks your focus on the highest-leverage knowledge, so you start building real projects fast.
- Work in tight squads that collaborate and co-evolve. Matches are based on your commitment level, execution speed, and the depth of progress you show in the early stages.
- Use a non-linear AI interface to think with AI. Not just consuming its output, but actively reason, paraphrase, organize in your own language, and build a personal model that compounds over time.
I'm opening this to a few more self-learners who:
- Can dedicate consistent focus time (2-4 hr/day or similar)
- Are self-driven, curious, and collaborative.
- No degree or background required, just the will to break through.
If that sounds like you, feel free to leave a comment. Tell me a bit about where you're at, and what you're trying to build or understand right now.
Top Comment: Hello. Is this open to people who have basically zero knowledge but are willing to learn from 0 and do what it takes? Because if it is I'd be very interested.
