Personally, I would like compilers to better exploit vectorization, which can get you 2x to 10x faster on random things within typical workloads, rather than worry about dubious optimizations that have performance improvements that may or may not be caused by changing the alignment of code and data blocks.

I would like to see more effort dedicated to basic one liners that show up in real code like counting how many of a given character are in a string. E.g. `for (str) |e| count += e == '%'`. For this, LLVM spits out a loop that wants to do horizontal addition every iteration on x86-64 targets with vectors, at least. Let's focus on issues that can easily net a 2x performance gain before going after that 1-2% that people think pointer aliasing gets you.

„It‘s entirely possible to sway your group of friends from WhatsApp to Signal“ is an assumption, I don‘t think is universally true. Especially since you base it on your own experience. I just recently made the switch but for me it meant cutting some contacts for now. Especially non-tech people put you in a tinfoil-hat category pretty fast so its not an easy problem if you can‘t communicate well enough.

"Even very rich nations have a handful of prototype plants for CO2 capture right now at best, and the budget for things like this is the first thing that gets slashed by Doge et al."

Might want to take a look at China, or at least what IEA writes about CCUS and the like there.

If you’re working with them I’d like to highlight that if they have a messaging platform with children on they are going to have to take safety extremely seriously. I know the laws in the uk are not popular here but the checklists of risk assessments are worthwhile doing - cases where people can privately message children are really high risk because you’ll get a bunch of people who really want to message children. If users can send images you’ll have CSAM to deal with.

And I blame the media. Politicians continue to post, and the media continue to quote them from twitter. I think it's shameful that politicians and other officials are using twitter as some sort of official media/announcement platform.

In my own African country twitter has become the de-facto channel for various updates and announcements by various state organs and officials. Makes it even worse when you consider the majority of the population has no reliable way to access this information.

And now its locked behind a user account! And it's owned by a potentially rival politician!

> Twitter's back-end is written in Scala, but they used "better Java" style so an average developer should have no problems making changes

You sound like someone completely oblivious to software development practices who somehow felt compelled to post opinions on software engineering.

Your choice of language is irrelevant if your goal is to maintain software. What matters is systems architecture and institutional knowledge of how things are designed to work. If you fire your staff, you lose institutional knowledge. Your choice of programming language does not bring it back.

Do libraries carry Mein Kampf? Would the books you suggest be categorized and contextualized appropriately? (… like all other books, and a job that I believe librarians already perform.) "Categorized and contextualized appropriately" might also mean "not on the shelf / by request, but available for research"; a good many books that are considerably less objectionable and of greater literary value already are in libraries, as there is only so much shelf. Again, deciding what merits shelf space is a function of the librarian.

But you see no qualitative difference between {a book written by a white supremacist, neo-Nazi organization; a fabricated text (i.e., propaganda); and a book the SPLC describes as "'widely revered by American white supremacists' and 'a sort of anti-immigration analog to The Turner Diaries', and attributed its popularity to the plot's parallels with the white genocide conspiracy theory."} and "The book Pride Colors by Robin Stevenson, which explains the meaning of the rainbow colors in the Pride flag"[1]?

What is the literary value of white supremacist drivel or a fabricated text to a community library? (I'd wager approximately none.) Versus the books being complained about (anything and everything LGBTQ+). (Definite value from helping people exploring LGBTQ+ topics for themselves, simply trying to learn about LGBTQ people, to helping non-homophobic parents raise inclusive, tolerant children who don't want to spread hate & intolerance, and which need only be checked out by those who actually desire to read them.) There is demand for books of the nature being banned here; I cannot see there being anywhere near the same demand for books filled with bile.

And again, the empirical position (and for some subsets, outright stated position) of the right is to remove any and all traces of LGBTQ media from libraries. (And more broadly, from society, as well.)

In this particular instance[1], we can see this in one of the complaints:

> “Our library should not be carrying ANY material about LGBT,” one person wrote.

and,

> “Family has 2 moms — unacceptable,” the person wrote of another book. They also complained, “This book makes LGBTQ+ look ‘harmless’ and acceptable.”

Someone else points out exactly your quip; what about equal representation?

> She continued, “You said taxation without representation. What about my representation in the library? What about what I want my children to read? What about the 4 percent [of] LGBTQ members in your community that you represent that only get 1 percent of the books? Are they not being represented fairly with their tax dollars?”

In the broader national debate, we've seen this pattern endlessly; "protect the children" is a wedge to open a fissure towards a wholesale and complete ban. E.g., see the FL Don't Say Gay Act, which started as objections that education on such topics needed to be "age appropriate" but was then subsequently expanded until is was a wholesale ban on education of numerous topics.

You see that scale problem everywhere. Once a business has become large, it no longer cares about “small” costs like unused buildings. That’s basically the reason so many buildings in towns and cities can be left unused for decades.

The impact it has on that town is often huge. But for the business, it’s just a small overhead. A small landlord couldn’t afford to leave their asset unproductive. A multinational conglomerate can.

The death of local high streets is in part due to the unwillingness of landlords to actually rent their properties out for market rate.

Lock-in. LLMs are today's hammer: everything looks like a nail now. LLMs are super useful for certain tasks (generating boilerplate code, generating tests, providing examples for API usage, summarising etc.), but the demo to me just illustrates a solution in desperate search for a problem. "Create A TODO" using a chatbot? That's an example gone wrong in so many ways and goes to show what happens if you start with a solution and work your way backwards to a use case without actually thinking about it yourself...

I think we're not in disagreement that both play a role. But maybe not in how much each contributes. My claim is that luck is often heavily underappreciated. That's not surprising - it's hard to measure, and it feels less good to attribute your success to something outside your control like random chance rather than your hard work, dedication, skill, smarts, whatnot. Nobody gets praise for luck, and ultimately success stories are often going after praise if they are honest with themselves. Which is fine, but don't discount the luck factor.

Just being born a white heterosexual male in a developed country somewhere between the 70s and the 2000s puts you so vastly ahead of everybody else that even if you don't tick all those boxes the luck factor is enormous. Few people openly appreciate that.

Public-private "partnerships" backed by private equity will always raise prices, cut costs arbitrarily, reduce service, take out loans, and saddle the organization with debt to pay themselves huge dividends before driving it into bankruptcy. This is what happens when corrupt, unregulated capitalism is allowed to run amok and have zero skin in the game except to extract maximum profit like vampires.

Significant pronunciation differences are related, but not covered in this list.

For example, in Ontario (perhaps elsewhere in Canada) the word asphalt is pronounced like “ash fault” (ˈæʃfɑlt) as opposed to U.S. pronunciation like “ass fault.” (ˈæsfɔlt)

Also “pasta” is often ˈpæstə as opposed to ˈpɑstə in American English.

Do you have any source for this extraordinary claim? It's practically a claim of perpetual motion.

Carbon dioxide a tiny fraction of the atmosphere, even in concentrations which are immediately harmful to human life.

At the moment it's 400 parts per million. So in order to extract 1kg of Carbon Dioxide from the atmosphere you have to pump 2500kg of air through the system. This alone makes it unlikely we can do this profitability.

You then need to extract the carbon dioxide using some technique which will probably involve cooling or pressuring that volume of air. Before finally transforming carbon dioxide, a very stable chemical compound, into a reagent which is actually useful (probably carbon monoxide).

> If you look at the actual profit margins it’s low single digit percentages.

Didn't I see somewhere that that's an artifact of Hollywood-style accounting? If you spin up a sub-business then have that sub-business charge high fees for services you can't live without, the main business might even be losing money!

What's indisputable is:

* in America, we pay more for less healthcare

* most of the money does not go to the doctors and nurses actually providing services

* it also does not go to research, which is funded elsewhere (assuming it keeps being funded at all)

* it's often possible to pay less for a service if you pay the provider directly rather get your insurance involved

If I'm being honest, the magic of Go was lost when generics were introduced. It now feels akin to Java, which I guess was inevitable and for anyone to really take it seriously maybe it needed to get here. But I am not a fan of generics. While that level of abstraction and composability is clever, it also lends itself to more complexity and systems that can be harder to concretely understand. Just an opinion that I know many will not agree with but I come from the systems side rather than pure software engineering. It's probably ironic considering go-micro leans heavily on interfaces for abstraction but in that there are many hard learned lessons.

There are several scenarios where it would contribute:

1. You have access to a charger at work 2. You’re retired 3. You take public transportation or bike to work (fairly common scenario in Europe) 4. Work-from-home (got more common after covid, I know many people who do it at least once a week now, and that’s generally enough to charge what you need to drive for a week) 5. You charge only during the day on weekends (should be enough to cover the week for most people, even if you feed say 20% of it back to the grid through the week) 6. Rental fleet operators (booking data can inform charge/discharge policy) 7. Residential batteries, where you charge the EV at night with what you got during the day, every day, but set up a policy where you allow both the home battery and the EV battery to discharge if the electricity is expensive enough. I could see myself making decisions about WFH or biking to work based on electricity pricing.

> Does a truly distributed solution have no additional cost at all?

If you literally just drop in etcd or Zookeeper rather than Redis and then develop in the same way then I'd say there's no additional cost to doing that. (I mean sure if you dig hard enough you can always find a way in which solution A is worse than solution B - e.g. most things have worse latency than Redis - but in this scenario the latency of the external API is going to make that irrelevant). Of course if you're just running those in single-node mode and developing against them without thinking about the distributed issues then you've still got plenty of ways to shoot yourself in the foot, but it's a small step in the right direction.

Developing more fully distributed from day 1 requires discipline that takes time to learn, but I'm not convinced that it's actually slower - I'd compare it to e.g. using a strongly typed language, where initially you spend a lot of time bouncing off the guardrails, but over time you adapt yourself and can be productive very rapidly on new projects.

> To be honest, for me, in an interview-type situation, if you insist that Redis is the problem in that scenario - you would have failed the interview (the interview is never one-way, interviewers can fail it too).

Interesting - to me Redis in a system design is very often a case of over-architecting. It's easy to use and programmers enjoy working with it, but very often it isn't letting you do anything you couldn't do without it, and while it can speed things up, I see a lot of cases where the thing it speeds up is something that was already fast enough.

Yep, and it doesn't make it right.

I recently told my bank I don't agree to their new privacy terms. I sent them all 26 pages, marked up with various red lines crossing out the objectionable clauses. One was about tracking pixels, web beacons and the like.

There was also much worse stuff contained like behavioral profiling and sharing my data with outside advertising conglomerates.

After-the-fact opt out mechanisms were described for a lot of it, but I explained very clearly that I am not consenting in the first place. The fact they provide an opt out for some of the most shameful portions reinforces that they don't need consent in the first place to provide me with banking services. I don't know who in their right mind would accept such terms. Unfortunately most individuals I know wouldn't have a clue what the jargon means or how it affects them.

A meeting was set up with my bank manager, and to underscore my point I brought in the original, aged-parchment paperwork I signed over two decades ago to open the account. That was only 5 pages long by comparison.

I also brought in a screenshot from Facebook that proved the bank uploaded some information about me to them in a Custom Audience customer list (a tool offered to advertisers that perversely deputizes them in Meta's quest to ingest all of our personal information). They have no business telling Meta or other third parties who I bank with (which is what the hashed uploaded lists are used to match & confirm).

The manager was quite understanding of my concerns and agreed none of what I objected to is legitimately needed to provide me with banking. I politely explained if they expected me to agree to this garbage I would take my personal and business deposits elsewhere.

I was pragmatic, and realize they're not going to reprogram their whole web portal just for me, but told them if they were going to go ahead and embed web beacons and the like in pages served up to me, or engage in more aggressive privacy violations, then they're doing so without my consent (an important distinction if I suffer damages down the line). In the end, my redlined version of their policy was affixed to my file to document that I do not in fact accept their terms, and they got to keep me as a customer. Not as good as a countersigned revised agreement, but enough to indicate my intent should consensus ad idem come into question.

I realize this was a lot of time and effort (and some risk of further nuisance if it failed and my accounts had to be closed), expended for something most people don't seem to care about. But the growing trend of companies outside tech adopting all our worst dark patterns really gets my gears grinding.

The story goes to show that if you choose to push back, sometimes you can win.

Good job Europe, keep blazing a trail which I hope my country eventually decides to follow.

The very first question's "accepted answer" is a red flag for me: the person obviously does not have time to debug the code. Inconsistent times are the logical necessity: the candidate will switch between exploration/learning, debugging, prototyping, and writing the actual production code, and the proportion of the time spent in each activity is dependent on the stage the project is in. If there is a tough bug reported by a user, I spend zero time coding; I spend time debugging (adding debug prints does not count as coding).
Ask HN: Would it make sense to have a "memes" tab for developer humor/stories?
by FerkiHN | 2025-07-10 06:33:57+00:00
I know Hacker News values high-signal discussion, but hear me out:

Many developers have funny, real-life stories or coding moments that others can relate to — bugs that felt like boss battles, compiler errors that haunted dreams, or memes that reflect the struggle of shipping code. These aren’t "memes" in the TikTok sense — more like inside dev humor, insights through irony, or just light relief after hours of debugging.

What if there were a small “mem” tab — like ask, show, or best — where the community could share developer-centric humor, stories, or short sketches?

Done right, it could still follow HN values: thoughtful, relevant, high-quality — just with a lighter tone.

Curious what others think. Would this dilute the HN culture, or could it be a useful way to connect through shared struggles and laughter?

> 3. Didn’t go well? I don’t remember twitter (x) crashing for days or data erased. Means that organizations don’t need that many people.

I don't think you have a solid grasp on the problem. To start off, Twitter did experienced major outages that it never experienced before. Also, you hire and retain people when you need to implement changes. If your goal is to cease any form of investment in your platform, like rolling out a new product or providing a new service, then your responsibilities are limited to keep the business barely aflost while coasting.

See it as a navy ship. You need full crew to perform all your missions, but mothballing the ship requires a skeleton crew.

Here you are, boasting that a ship doesn't require more than a skeleton crew to be kept afloat. I mean, sure why not? But are you saying what you think you're saying?

Health insurance isn’t a great example. Profits are capped relative to premium costs so denying claims isnt a good strategy.

The only way denying claims can become a profit booster is to deny enough that premiums can be lowered enough to bring over more new members than was lost in revenue through the premium discount.

So denied claims come from people shopping for the cheapest insurance coverage possible.

Can't some shady legal firm now just dig out who is in the exact same situation as this user, and sue on behalf of them, keeping (say) 10%? I'd be happy to let them.

But in the end this kind of thing shouldn't be regulated by lawsuits from individuals. The fines as I remember it can be up to 4% global annual revenue and it's about time someone actually handed a fine of 4% global annual revenue to a company the size of Meta, so companies finally realize that the law isn't just a recommendation.

If you're using an LLM and you are surprised it makes things up, I don't know who to blame?

The overblown claims? The systems prompt "team" that ensure "I don't know" can never be uttered? Or user expectations?

I find it unfair to blame users, but I tend to think creating a system prompt that accentuates "with an air of certainty" over ... straightforward honesty, both telling of the org culture, and the wider trend of "look like you know"...
