Top 5 Developer Articles of the Week on CoderLegion

Every week, the CoderLegion community brings together developers from around the world to share practical insights, experiments, and honest experiences from the trenches of coding.

Here are the five posts that made the most impact this week — whether through comments, reads, or shares — all written by real developers who love to build and learn.

1⃣ Null: The Billion Dollar Mistake

by Max Contieri Read the full article → https://coderlegion.com/6462/null-the-billion-dollar-mistake Sometimes the biggest performance wins come from rethinking your tooling. Tony shares how embracing safer patterns around null references can drastically reduce production incidents — and what trade-offs came with it. A must-read for anyone still battling NPEs.

2⃣ Vibe coding is bullshit if you don’t know what you’re doing

by Kenliten Read the full article → https://coderlegion.com/6497/vibe-coding-is-bullshit-if-you-dont-know-what-youre-doing Readable code doesn’t just improve quality — it preserves sanity. Ken breaks down why “vibe-coding” (jumping straight into AI-scaffolded apps) may look fast but can cost you maintainability, clarity, and long-term control.

3⃣ The post compares G1, ZGC and Shenandoah Java garbage collectors

by webMethodMan Read the full article → https://coderlegion.com/6543/the-post-compares-g1-zgc-and-shenandoah-java-garbage-collectors AI tools like Copilot and ChatGPT are reshaping how we code — but should we be worried or excited? This deep dive sparked major debate this week on how developers can adapt GC tools, choose the right collector, and manage performance in large-scale Java apps.

4⃣ My SQL Mistakes Almost Broke Me… But I Learned a Lot

by DuchessCodes Read the full article → https://coderlegion.com/6542/my-sql-mistakes-almost-broke-me-but-i-learned-a-lot Rust can be intimidating at first, but DuchessCodes’s personal journey in SQL captures both the frustration and the aha moments. She shares real mistakes (including wiping a table without a WHERE clause) and the lessons behind them.

5⃣ Building a Robust API with Laravel, Clean Architecture and SOLID Principles

by Fernando Richter Read the full article → https://coderlegion.com/6596/building-a-robust-api-with-laravel-clean-architecture-and-solid-principles Debugging isn’t just fixing bugs — it’s a mindset. CodeForgeTemple walks through building an API in Laravel + Clean Architecture, emphasising SOLID principles, error handling, and what every junior developer needs to know about designing maintainable systems.

Similar for me, also in Ontario. I got a three zone mini split this year that I’m hoping can cover most of the shoulder seasons and keep me from using the gas boiler, though it remains to be seen if that’ll actually pan out; so far the kids have complained that their rooms are a lot less evenly heated when it’s the heat pump running rather than the rads.

I'm jealous of your financial learnings. However, your model is not accurate as it doesn't factor in the 4 degree improvement in comfort and indoor pollution from propane furnaces: Propane furnaces can cause indoor pollution through the release of pollutants like carbon monoxide (CO), nitrogen dioxide (\(NO_{2}\)), and benzene, which are byproducts of combustion.

It also doesn't include the negative externalities because of tragedy of commons. Sadly, these kind of flawed 'financial' calculations are widespread.

What is inspiring from the OPs comment is that this is doable in harsh Canadian winters with negligible solar and it breaks even. Most of the world is living in significantly more sunshine, so it should work out a lot better financially for >99% of the population.

I hate this bullshit employee. But, in reading the post, I was not sure the OP was "the boss" as he stated he was "team lead" [Then I joined as the lead. I helped to stabilize the team over the last year. It’s grown from four to ten engineers. Three engineers joined specifically to work with me.] So, that's why I advised to better understand what is going on. I've been a "powerless" team lead more than once, and if you are not doing reviews and if the "manager" is not actively involved in making the team better but using input to perform a review, then its really frustrating. So, either he has the levers to fix the problem or he needs to go to his manager and figure out what levers there are to fix this.

There may not be any "free messaging" or similar offers is my guess. In fact using ECH it is already possible to spoof the SNI but make a real TLS handshake to the underlying domain; you can try it on my test website[0] with wireshark open on the side (if your browser supports ECH)

My personal anecdote? Don't.

I have a house where the first floor is served by a gas/ac combo unit, and the second floor with a heat pump.

I literally see no advantage to the heat pump and wish I didn't have it. It takes forever to heat and cool, comparitively, and likes to ice over when it gets too cold in the winter while running 24/7 doing nothing. The emergency heat eventually kicks in and fixes it, so I'm considering just running emergency heat all winter.

> How could updating the software possibly make a difference here? If the encryption is cracked, then who is to say who owns which Bitcoin? As soon as I try to transfer any coin that I own, I expose my public key, your "Quantum Computer" cracks it, and you offer a competing transaction with a higher fee to send the Bitcoin to your slush fund.

So if this understood knowledge, it means you cannot really transfer to quantum safe algo for Bitcoin. Are we only ones aware of this? Because if this true, it's actual alpha and Bitcoin should be sold asap and exchanged for land and physical gold.

Am I wrong here?

Win32 will be preserved forever in a glass museum case with life support bolted on -- just like how in Valve’s Source Engine, the Quake physics component (Qphysics) is treated as a ancient artifact to be called upon when its power needs to be channeled, but kept isolated from the "normal" VPhysics lest its Eldritch power corrupt the rest of the codebase.

Though judging from how CS2 is going, it seems that the quarantine measures aren’t particularly airtight.

I looked into the precharged DIY option and the lengths just didn’t work out for what I needed in my space. I ended up paying a licensed installer C$12k to put in a three head system (two conventional, one ducted), and then a separate guy $5k to do the ducting for the bedroom level.

It would have been nice to do it as one, but the HVAC firm didn’t want to get their hands dirty with my wacky ducting plan, and the duct guy wasn’t licensed to charge the refrigerant lines.

Yea, I run wireguard & OpenVPN on port53 (different VPS) just in case it works. Unfortunately my experience with the "pay to use" WiFi so far has been they validate that port 53 is valid DNS traffic, and often don't allow arbitrary resolvers (e.g. `dig example.com @1.1.1.1` will not work)

Corporations are bad because the diffusion of responsibility and legal liability shield turns them, to a first approximation, into amoral paperclip maximizers that will employ slave labor to save nickels and dimes.

The invariably sociopathic leadership is a symptom, not a cause: they're the least encumbered by ethics, and the best fit for corporate leadership.

The cure is a strong regulatory state.

Wow. Looking at the schema for gif, it’s so readable, I can’t help to wonder why something like this hasn’t become the standard way to work with binary formats over the decades already!

Seems like eveything has to be JSON and text based these days, because binary is more difficult DX.

When reading articles discussing binary formats, I usually see them using box diagrams of packets, description tables or hexdumps.

This neatly describes nested structure, names and ”types” - just enough.

I wonder if there’s a hexdump like viewer in IDEs that can present binary files like this? I can also imagine a simple UI to make the files editable using this.

I believe there are some high concurrency hash tables out there where the data structure contains two tables, and so each get results in a constant number of fetches, but the count is almost always greater than one. But if it avoids concurrency issues that ends up being acceptable.

I remember Cliff Click presenting one that was lockless and if I'm recalling correctly, where capacity growth operations could happen in parallel with reads. And possibly writes.
by noduerme | 2025-10-25 06:43:18+00:00
Yeah. As a debugging aid, I think it's fairly solid at surfacing things to look at and fix manually. And when you do that, you're actually hoping for more false positives than false negatives - which plays to the strengths of an LLM. When it comes to asking for rewrite suggestions for anything, I have to really go over its logic with a fine-tooth comb, because there are usually edge cases that can be spotted if you really think through it. I abhor its tendency to use try/catch. I've seen it write weird SQL joins that slow down queries by 30x. I'd never trust it to debug a race condition or to consider any side effects outside the 30 LoC it's currently looking at.

I guess I wouldn't trust it to confirm that new code would give the same result, but it can't hurt to ask, since if it told me the code wouldn't, that would make me look more closely at it.

I think as long as you look at it as part of a distillation process, and aim for false positives, and never actually trust it, it's good at helping to surface issues you may have missed.

> I'm sure if such a relationship became public,most Americans will forget about it in few weeks time and half will be surprised what the big deal is. But apple will lose out on Asia and Europe where it has solid competition. Their hardware is their bread-and-butter.

Everyone is somewhat aware that their phone are not impermeable to government agencies and it doesn't matter, that's the case for Americans of course because they are well used to it, but also for Europeans.

If they were to purposely make 'mistake' to allow Israeli spying companies to compromise their phone, it most likely wouldn't change anything.

REST, including HATEOAS, was largely retrospective documentation of the architectural underpinning of the WWW by Roy Fielding (who played an important role in web technology from 1993 on, was the co-lead for the HTTP/1.0 spec, the lead for the original HTTP/1.1 spec, and also, IIRC, lead or co-lead on the original URL spec. The things it documented existed before it documented them.

No. There is 0 reason to be toxic or an asshat in general. It should not be accepted. He might have reasons to be protective, but one can do that in a respectful manner. But going around, making something up, banning people for asking or criticizing is not the way to go.

Once you make something public it's not a private garden anymore.

The role of the engineer in large enterprises with deep legacy systems is indeed quite like a surgeon, but not for the reason suggested. Rather, it involves delicate operations on a complex and confusing object that you didn’t design or build, that maybe nobody really understands in full, where simply locating the problem is more than half the job, where parts depend on other parts in unexpected ways, where one tiny mistake can have catastrophic consequences, and where a litany of credentials and clearances are required before they’ll even let you near the operating table.
by gf000 | 2025-10-25 06:48:27+00:00
There is nothing mathematically 100% safe, the human meaning of the word inherently involves some kind of uncertainty.

Going for a test itself via car has a quite significant risk itself, should the doctor say that you shouldn't move out of this room, it's not safe?

Like even regularly used medicine has some slight chance of an adverse reaction, that's how minuscule side effects multiplied to human population times the number it's taken results in.

Guess what often has many orders of magnitude greater risk? Continuing having the disease you went to the doctor with in the first place, or having it lie undiscovered.

I was in a intercontinental flight few weeks ago and when everyone was sleeping my wife was able to open Instagram and scroll the feed, while other websites were not accessible. I did not have a PC with me, but I immediately guessed about they are doing filtering based on SNI. Appliances like Allot or Sandvine are in this market since more than a decade.

> You aren't saying hypermedia/hyperlinks served by a backend equal hateaos are you?

That’s exactly what it is.

> hateaos is from 2000 isn't it? Long after hyperlinks and the web already existed.

> Over the past six years, the REST architectural style has been used to guide the design and development of the architecture for the modern Web, as presented in Chapter 6. This work was done in conjunction with my authoring of the Internet standards for the Hypertext Transfer Protocol (HTTP) and Uniform Resource Identifiers (URI), the two specifications that define the generic interface used by all component interactions on the Web.

This is straight from the intro of fielding’s doctoral dissertation.

Very common in Germany. Non-existant in Finland. Finnish consumer rights are very weak, they only work if the business cooperates[1]. Finnair is a state-owned company that acts like if they were legislation and courts themselves. I have avoided them as much as I can for many years.

[1] Probably the majority of businesses does. But shady used car dealers etc. and Finnair don't.

I think "discuss" is actually an interesting and probably accidentally specific (and correct) choice of word here.

If you look up the definition, you find

> to talk about a subject with someone and tell each other your ideas or opinions

> to talk or write about a subject in detail, especially considering different ideas and opinions related to it

In contrast, the garden text:

> You can take inspiration from it and bring that home to your own garden, giving it a personal twist and adapting it as needed. You can even make friendly suggestions if you have a really good idea that ties into the vision that is already there.

Sadly, my sense is that the article's author doesn't understand passenger rail. Nor RR safety. Nor history. And doesn't want to.

> ... a professor of urban and regional planning at Florida Atlantic University who has lived in the area for most of his life. “Brightline is unique nationally,” he said. “It’s operating right through the urban fabric.” Just by leaving their houses, people encounter it, whether they want to or not, and they sometimes have to react quickly, in a life-and-death situation, to a system they don’t intuitively understand. “This is why we see the issues that we have,” he said.

Vs. I live in SE Michigan, and RR tracks go right through all sorts of urban and residential areas. One little old train station near me is now a Montessori preschool. Back in the 1940's, my mother found herself in a situation similar to the elderly couple the article describes dying - but at a grade crossing with 6+ tracks, and boxed in by cars with oblivious drivers. However - the house she'd been born in was 2 doors down from a multi-track grade crossing, and she understood both "there is more than one train in the world" and "sit on the tracks and you will die" - so she got the hell out in time.

That doesn’t explain Bitcoin’s price. Even if what you say is true, assuming BTC gets cracked within 2-3 years, smart money would get out of it and would go into real estate, land and physical assets instead. Why isn’t this happening? I mean anyone who is able to graso exponentials and there are a LOT of people who can, will come to same realization.

Also, you can’t really switch Bitcoin to quantum-proof algo. It’s pretty much inpossible.

This is phenomenal advice. The post itself strikes me as either lifted directly from reddit (experienceddevs or another sub), but your advice is generally great for any reader curious about how to handle this type of problem employee.

From the perspective of a line manager, your statement about not coddling and directly confronting the issue intuitively sound correct. If it's possible to address behavioral issues in this type of high-talent high-friction engineer, it actually doesn't hurt to bruise their ego a little--if anything, doing it respectfully means they listen, and value the feedback more than usual.

Edit: also, took a look at your profile--couldn't tell, what type of org are you VP of eng at? (Private, equity-funded, late-stage, early stage, fintech, biotech, saas, etc.). Curious as the advice rings sound, but I only saw your consultancy work.

Well, that just goes to show that these tools are wildly unpredictable. I've had bad experiences generating Go, whereas I've read many experiences of the opposite.

> I chalked it up to the LLMs not having a large enough corpus of training text.

I'm inclined to believe the opposite, actually. It's not so much about the size of the training data, but the quality of it. Garbage in, garbage out. Typst is still very young, and there's not much bad code in the wild.

And the language itself plays a large role. A simple language with less esoteric syntax and features should be easier to train on and generate than something more complex. This is why I think LLMs are notoriously bad at generating Rust code. There's plenty of it to train on, but Rust is a deep pit of complexity and unusual syntax. Though it helps when the language is strict and statically typed, so that the compiler can catch issues early. I would dread relying on generated Python code, despite of how popular and simple it is on the surface.
by jmogly | 2025-10-25 06:54:14+00:00
Respect, sometimes we forget that our software is actually supposed to do stuff. Will say though you can have both, especially now with llms where you don’t have to trim each piece of wood yourself. Also, it’s not always about cutting corners to make a buck, sometimes it really is about creating a great product that people love using. Engineering quality is part of that.

I don't know why you're being downvoted (it shows as slightly greyed out). This is true. I had a roommate who is a HVAC salesman. Very smooth talked. The 'HVAC' company offers free HVAC maintenance. They techs go in, do some stuff and they point out some problems. Sales guy goes in, smooth talks his way to 5K - 70K bill to most people. Of course, when something goes out and people don't have a choice (like in peak summer or winter), they make out like bandits.

Most of the local firms (Dick's local $town hvac/plumbing/electrical) are owned by massive PE firms (Saudi + other billionaires) which pretty much own the entire businesses all over US. They keep the local name to make people believe they are giving business to a local guy.

Another roommate of mine was a plumber.

The guys who do the actual work get paid close to nothing ($20 - $22/hour) and live on day to day basis.

Plumbing company quoted me $3000 to replace a broken water heater in the middle of peak winter. I paid my guy $300 for labor (heaters are $500 - $1000 from lowes depending on how long of warranty you want) and he was super happy for making a lot of money.

"In the era of AI and data-driven enterprises, reducing architecture debt will no longer be a technical choice. It will be a strategic differentiator that separates the companies that can transform from those that will fall behind."

Yeah. Whatever.

How is AI even related to architecture debt in software? By vibe coders forgetting to specify "decent architecture" in their prompt?

Same for data driven. For most companies data driven just means focusing on one more or less relevant metric, but ignoring all rational arguments on topics cannot be measured in an easy way. Leading to short term thinking and optimizing for a metric instead of for business success. Not great, but still not a lot to do with software architecture.

And as much as I'd love software architecture to be a strategic differentiator: It really is not. Companies need software that is good enough. Good and consistent architecture just lessens the developers pain in dealing with it (and technical/architecture improvements are much more fun to do, since there is no customer with strange requirements). There are many companies out there with horrible software quality that still succeed.

Surely Linux should be developed Google style, with a Web Scale perspective. uucp, tar, yacc, roff removed (with a 30 day notice, of course!), all the uses of "creat" amended to add the final "e", etc.

And systemd already follows Microsoft best practices, such as "Fire and Motion" https://www.joelonsoftware.com/2002/01/06/fire-and-motion/

The article seems a few months too late. Claude (and others) are already doing this: i've been instructing claude code to generate code following certain best practices provided through URLs or asking it to compare certain approaches from different URLs. Claude Skill uses file "URLs" to provide progressive disclosure: only include detailed texts into the context if needed. This helps reduce context size, and improves cachability.
by trashtensor | 2025-10-25 07:00:44+00:00
Big companies tend to have Staff/Principal/Distinguished type roles. Usually those roles give you a lot of independence. But that independence means you need to be able to find projects to do and advocate for them and get them staffed and planned and executed and out to production. Often those projects can span many teams and multiple organizations, depending on how the company is structured. So I suppose the most valuable skill is being able to earn the trust of the managers so that you're able to even get them to listen to you so your stuff ends up on their roadmap.

so i do sympathize with a lot of the negative sentiments about the role here in this thread, and i think that in general there is a lot of navel gazing about the staff+ tech ic roles, there is an actual place for them as tech leads of large projects.
