Youtube would be a prime example: I’m guessing the storage required for the metadata of all videos is too large to be stored on a single server, so how do they achieve millisecond-level performance on searches and handle millions of queries routinely?

And how to do it? Looking for a tutorial.

I’m currently learning js as my first programming language. I want to learn DSA and leetcode for getting a job

I’m guessing that we’ll see lots of news in 2026 about how companies are hiring developers to help improve the memory efficiency of their software because they just can’t get enough servers. Also, the servers they do get will have reduced RAM compared to what they wanted.

I’m looking for a way to wrap up a cloudrun API that does an automated analysis behind a paywall, and I’ve never done any of this kind of billing etc.

I've absolutely grown to hate everything AI/LLM related.

For context, "no hello website" is a term I'm using to describe websites like https://nohello.com. The gist is that it's trying to get people to no only say "hello" but also ask whatever it is they're trying to ask you about. (In my opinion, this can even extend to generic conversations, like "hey, how are you?" versus just "hey!")

I'm a Senior Principal Engineer at a large tech company. My work is to define the 1-3 year future for a $1B slice of the company's revenue, that 1% of it's employees work on.

I'm looking to set up a server of some kind that I can use to store more or less arbitrary files on demand.

I'd like actual examples instead of "I work faster", something like "I can move straight to the middle of the file with 7mv" or "I can keep 4 different text snippets in memory and paste each with a number+pt, like 2pt", things that you actually use somewhat frequently instead of what you can do, but probably only did once.

I'm a senior engineer (web full-stack) at a bank. I've been doing this for about 5 years.

US, Georgia if it matters.

im using peerJS and its configurable as described here: https://peerjs.com/docs/#peer-options-config

hope this question doesn't sound too vague.

Hello fellow devs.

I work in research (uni) and am writing a framework for heat processes to optimize their costs. This goes both for private houses and industrial processes. The goal is to enable industry players to see that/when renewable energies and heat reuse with heat pumps are cheaper than fossil fuels. I do this using digital twins for components and on a system level.

I'm just so exhausted these days. We have formal SLA's, but its not like they're ever followed. After all, Customer X needs to be notified within 5 minutes of any anomalous events in their cluster, and Customer Y is our biggest customer, so we give them the white glove treatment.

The problem is I am using beam.ParDo to call api, to enrich my data.

I want to document my debugging sessions in a text file but I don't know if anyone did this before.

Sorry for the burner account.

I'm really enthusiastic about anything involved with Unix/Unix-like operating systems and their ecosystems (Mostly Linux and a bit of BSD variations). I also know a couple of programming languages including C, C++23 and OCaml. But other than doing a couple of tiny projects mainly to practice my programming skills in the languages mentioned above, most of my experience is theoretical and it comes from reading books, blogs and watching conferences.

Referring more to smaller places like my own - few hundred employees with ~20 person IT team (~10 developers).

I'm thinking of ways to help people move from established software to more open, flexible forms that don't lock them to another organization.

I am professionally a software developer for 8 years and I simply don't have ideas for personal projects (Can't find any problem that I can fix with programming). At times I feel like that's natural and I shouldn't worry about it. But on the other hand, I do like to imagine having something personal that I can work on so that even if some days on my main job are not satisfying, I can always work on my hobby project and find that missing satisfaction.

Imagine, your are a Java developer with multiple years of experience in the job. You really like working with the language.

I've been doing some interviews lately, and my most recent one seemed to be my most promising one so far, until he started doing what he called "light tech screening" and did some trivia questions to test my knowledge on what goes on under the hood. I do admit, I should have been better prepared on the topics, and didn't do as well as I could have. At the end, he said my experience was interesting but I needed a better grasp of the fundamentals, and that we should keep in touch. Afterwards, I messaged thanking him for his time, and that I needed to review my course material, asked if he thought I should review anything specific and if I could do that for a few weeks and revisit it like he said. He suggested I do a deep dive into JS/TS to really understand what goes on and why, and would be happy to revisit it in a few weeks, and again said to keep in touch.

My current team runs weekly retrospectives using the Lean Coffee format. More and more, I find that the items people are bringing up aren't really important or could just be a question in Slack.

Would I have to drive there myself or could I pay an on-site tech to do it for a courtesy fee? Does it depend on the company?

I've interviewed for and been interviewed by companies large and small. We all know software engineer job interviews suck. But it's hard on the other side of the table too.

We have a team AMA coming up with a director. Apart from the typical "what are plans/goals for the team" type questions, what else could be useful or insightful questions?

Was just wondering what's popular nowadays, maybe I find something new and better - what kind of tools are you using to access and manage databases?

I'm looking for an external monitor for both programming and gaming. Currently, I'm using a 1080p monitor, but I'm tired of turning my head between the macbook and the monitor when I have to deal with 3+ windows.

Hi.

Hi experienced devs , I am a beginner programmer. I mostly use code completion and go-to source , and rename function and objects, code-pretty. Other features not so much. What features do you use often And what features are not that useful in an IDE and can be considered bloat? P.S.- Which is that one feature that you can't live without?( sorry for sounding like tiktok wannabe)

I am opening a woocommerce store pretty soon and I was looking through a various drop shipping/fulfilment on demand services. One of them offers their services through an API and there is some documentation on it, and how to run a test if it works correctly on my end but no information on how to "install" it on my store.

I got this article in a reply to a different conversation, and for the most part I agree with it. Gpg is old and we have better ways. I like signing my commits, I like feeling that these commits are actually and provably mine. But I'm not married to GPG like I used to be, I'd like a better way. The problem is that git used gpg for signing. I learned about this new thing called minisign and I wanna use it with git. So how do we switch? And if we can't switch, then how do we fix GPG?

For a personal project, I’m not exactly sure how to decide between cross-platform mobile frameworks (e.g. React Native, Ionic, Flutter, etc.).

I know this is a very generalized question, as it depends on the company, product, position, etc. But in general, what sets someone apart as ready for a senior position over an intermediate or junior position? Experience I would think would be a big one, but say you have a candidate that shows problem solving abilities to solve code problems, but is newer to the tech field vs someone who's been in the field x years, does the first guy have a shot without really knowing the ins and outs of working as a software engineer, hoping to pick it up quick?

A friend of mine has an eCommerce company of ~30 people. They're now collaborating with an Odoo Partner to implement Odoo as their ERP. He wants me to become their Odoo Developer and Maintainer in the future. He wants me to not just know how to code, but also understand the parts the business is running. From where should I start learning?

Over the years I feel brainwashed by the thoughts of others with no willpower to affirm my own beliefs.

I'm well aware this post has been asked to death on Reddit, but I couldn't find anything relevant on Lemmy so I thought I'd give it a shot.

And does it matter if they show up on applicants LinkedIn profiles or just resumes?

TLDR: I am not talking about the CCNA material (which is great for learning networking, albeit a bit too much detail for software devs), I am asking about the certificate itself, is it worth it to spend months preparing for the certificate, spending $300 on it, passing it and then putting it on your resume? Does it matter if I am open to move to DevOps positions in the future?

I have a repository on github for a project that deals with importing/processing/sending reports to clients. There is now talk of creating a similar application for a different set of users, without the import part, but multiple send parts. The existing code base already has 90% of what the new application needs (and some extra that is not needed for this new project).

What advice would you give to someone who is trying to teach themselves software development skills? I'm doing that right now, and I'm finding it easy to understand, yet difficult to implement in computer code. I want to move onto more advanced stuff, but I feel that I don't have enough experience quite yet. What skills/courses would you recommend I take? How did you get better on your coding journey? Any tips to make the process go faster? Thanks in advance!

I know other version control software exists, but does anyone use it? Why? What are the differences? All I've ever actually seen people use is git.

I'm a back-end developer who wants to play with some desktop/front-end development.
