Conceptually, you can think of it as "RAID for memory".

A consumer DDR5 module has two 32-bit-wide buses, which are both for example implemented using 4 chips which each handle 8 bits operating in parallel - just like RAID 0.

An enterprise DDR5 module has a 40-bit-wide bus implemented using 5 chips. The memory controller uses those 8 additional bits to store the parity calculated over the 32 regular bits - so just like RAID 4 (or RAID 5, I haven't dug into the details too deeply). The whole magic happens inside the controller, the DRAM chip itself isn't even aware of it.

Given the way the industry works (some companies do DRAM chip production, it is sold as a commodity, and others buy a bunch of chips to turn them into RAM modules) the factory producing the chips does not even know if the chips they have just produced will be turned into ECC or non-ECC. The prices rise and fall as one because it is functionally a single market.

Apply the same logic you did to chair acquisition to headphones. Yes, the good stuff costs more, but also lasts longer. I bought top-end turtle beaches a while back and actually saved because I can use them on my work and home machines, and they sound great. Metal band, low pleather (which always fails after 6 mo to a year), great sound, Bluetooth, 2 dongles for 2 devices. Win.

You got it. The LVT doesn’t work unless it’s so high it can force Grandma out of the house she grew up in, the one she thought was built on “her” land in Alameda.

It has to act like a market rent paid to the government, or it can’t induce the behavior changes it’s supposed to.

Hard to believe Americans, at least, would accept that shift in property rights.

> are the taxes to be so large punative that half of everyday home owners need to sell up?

Yes, either you are rich enough to occupy land in an expensive area for a suboptimal use (usually means central to transportation and population), or you have to give it up to someone who can make use of it.

Note that homeowners who live further away from stuff are not impacted. It’s for underutilized lots that are being squatted on due to someone laying claim to it first decades ago, but that is not an efficient way to allocate resources in a society.

Hence, why China can develop rapidly to benefit 80% of its population, while other developed countries are stuck catering to 20% of its population who got theirs first (or really, their ancestors did).

Eh, newtons theory of universal gravitation is still a theory, even if he had no access to particle physics, and even if later the Theory of General Relativity (among others) largely supplanted it. It’s also still useful (and used!) in most real life engineering situations. It’s rare where time dilation applies in say civil engineering.

That folks with Autism and ADHD may have large portions of their symptoms occur because they focus too much on some specific things, to the detriment of others - like emotional well being/regulation - can still be falsifiable (better than most psychiatric theories for sure!) and useful clinically.

Personally, it lines up with what I’ve seen and experienced.

That there is another (perhaps chemical, or brain structure) theory too doesn’t necessarily change that!

As an ex-Unity dev, it's clear Unreal crushes Unity on the "AAA" vibe side, and Godot marches forward on the "indie" vibe side. The writing was on the wall - I personally switched to Godot and couldn't be happier. Tools have new versions before being deprecated, bugs get fixed (and fast!), and there's no looming threat of Unity coming down and squeezing more money out of our products

I'm curious what you use its ai for?

so far I only use it to come up with long and chained commands I don't remember.

for example, kill all processes match certain pattern,

count the lines of code of certain files under a repo

kill processes listening to certain ports.

but other than a few use cases, I don't use it much.

I'm asking, because before warp came out, I also thought about creating a terminal as a side project. I hope to understand how important the ai feature is for today's market. I love warp's usability, but I don't find its integrated ai that useful.

As a parent I can’t stand Roblox. A while back Bedwars game on it was all the kids would talk about, then it was Grow a garden, now the worst of them all, Steal a brainrot.

Friends turn on friends and steal their items. Lots of crying and yelling. My child starts having tantrum if they can’t play. A friend’s child started hitting them with fists because they weren’t allowed to play.

The problem is that all the kids play this game and it’s their form of communication so I don’t want to completely ban it. Right now I block it on the router during the week and only allow it on weekends or when friends come over.

My other complaint is the currency they use, Robux. After 10, all kids want for their birthday is that. Some kids spend it on the stupidest things. When they run out of currency they go into a game called please donate and beg for more money. They also trade rare items for currency and some make items and sell them in the store to make money.

If the kid is banned by parents they find creative ways to play, they hide the app from Home Screen and play when studying, or wake up really early to play on their device, they play on school laptop using websites that run android emularors, etc.

I guess I’ll mention something positive as well. One child I know actually enjoys building their own games and publishing them. It rare thought and I haven’t seen many kids do that. They usually load up Roblox studio, play around with it for a bit and never ouch it again.

I miss the days of creative fun with Minecraft and wish the kids would have played that instead of Roblox.

Surprising they took so long. Most wealthy Chinese exfiltrate their children and as much of their capital as they can get away with from the clutches of the CCP. That's why there are so many Chinese twentysomethings driving Ferraris in Vancouver, and changing them every 6 months. Also why China has put tight controls on buying real estate abroad and banned bitcoin

I notice that angry hackers are going nuts with their down votes. Make an argument instead if you have something to say.

Tourism and travel is one of the worlds largest industries, and companies in that sector can improve their revenue with double digits if they can reach and communicate with more customers. That's real impact, which is worth something, while hacker votes are worth nothing.

I think this concept is good from the perspective of focus and targeting issues, meaning that de-emphasizing certain issues seen out of touch with the mainstream is important. But remember that a lot of that is the fruit of the right's propaganda arm, Fox News and all the rest, hanging cultural albatross in order to push the perception that candidates are extreme left. One of the most successful things about Mamdani is message focus - he's as good if not better than Bill Clinton - which if managed correctly can become shared talking points. Having a central messaging office like Fox News is what sits behind most of the Republican Party's success. Of course, one must be careful to ensure the messaging does not start to warp reality, which explains much of what has gone wrong with the Republicans. (e.g., They believe their own Bullsh*t)

I use em dashes for the same reason that I use semicolons: it’s how I’m hearing the sentence in my head as I’m typing it.

I think it’s a bit of a stretch to call a part of grammar pompous. It’d be analogous with me calling your post lazy due to its various typos — I’m not, I just found the comparison apt.

Yes. $30/victim is the negotiated amount at which the lawyers make an acceptable profit.

I'm talking about the lawyers who initiated, orchestrated, and covered all costs associated with the class action lawsuit.

They typically get ~30% of the announced settlement. The headline figure in this case was $5M, so the lawyers likely got ~$1.5M.

That has nothing to do with the worth of each victim's information.

Unity is absolutely being squeezed between the two. I can't really see how it can compete with Godot at the low end; it's hard to compete with free, and most of the goodness in low end games is the gameplay logic, not graphics or animation. And Godot can only get better; look at how Blender ate the CGI tools market. This leaves Unity having to either compete with Unreal at the high end - a very high bar - or somehow finding a new business model. The switcheroo they tried to pull on their customer base can best be viewed in that light.
Tell HN: Archive.today Partially Inaccessible

Since beginning of november, maybe since end of october, archive.today is being inaccessible in Estonia. Tested in different devices and networks. There is endless captcha cycle. Same happens with other archive.today domains, like archive.ph.

That issue isn't only Estonian related. Similar problem seems affect web.archive.org. Last time archive.today was successfully accessed (redirected) was 3 october. Manually archiving gives error "Cannot resolve host archive.today."

> One thing that needs to be emphasized with “durable execution” engines is they don’t actually get you out of having to handle errors, rollbacks, etc.

I think this is a gross misrepresentation of what durable executions are. DEs were never expected to magically eliminate the need to handle errors. What DEs do is provide an high-level abstraction of the same pattern that is recurrent on all workflow engines, and they provide a simpler way for developers to implement rollback and compensation steps when workflows fail.

If you are designing and implementing a transaction with a DE, you still need to design and implement a transaction. DEs simplify much of the logic, but you still need to design and implement a transaction. There is no silver bullet.

> Even the canonical examples everyone uses - so you’re using a DE engine to restart a sales transaction, but the part of that transaction that failed was “charging the customer” - did it fail before or after the charge went through? (...)

That's immaterial to the discussion on DEs. You, as a software engineer, still need to design and implement a transaction. DEs greatly simplify your job, but you still need to analyze failure modes and perform the necessary compensation steps.

> All of these problems are tractable, but once you’ve solved them - once you’ve built sufficient atomicity into your system to handle the actual failure cases - the benefits of taking on the complexity of a DE system are substantially lower than the marketing pitch.

I completely disagree, but you do you. Some durable execution engines greatly simplify tracking state and implementing activities and rollback logic. Some cloud providers even provide services that allow you to implement long-running workflows with function-as-a-service components that provide out-of-the-box support for manual approvals. If you feel you are better off rolling your own support, good for you. Meanwhile, everyone around you is delivering the same value with much less work.

I was diagnosed with ADD as a kid (before it was ADHD). People always describe the disorder as "lack of focus" but that's a really poor description for what I have.

I would say I have "hyper focus", to the point where if I'm working on something interesting, I will lose track of time and am unable to redirect my attention to anything else.

This makes me incredibly "spacey" as often my mind is still fixated on the task even long after I've stopped working on it. It also makes it very hard for me to accomplish any task I don't think are interesting...

And often a new idea will strike me like an epiphany that immediately takes the top spot of my attention.

The result is I have hundreds of half finished projects in flight across countless areas of interest.

The funny thing about event sourcing is that most teams adopt it for the sexy parts (time travel, Kafka, sagas), but the thing that actually determines whether it survives contact with production is discipline around modeling and versioning.

You don’t pay the cost up front, you pay it 2 years in when the business logic has changed 5 times, half your events are “v2” or “DeprecatedFooHappened”, and you realize your “facts” about the past were actually leaky snapshots of whatever the code thought was true at the time. The hard part isn’t appending events, it’s deciding what not to encode into them so you can change your mind later without a migration horror show.

There’s also a quiet tradeoff here: you’re swapping “schema complexity + migrations” for “event model complexity + replay semantics”. In a bank-like domain that genuinely needs an audit trail, that trade is usually worth it. In a CRUD-ish SaaS where the real requirement is “be able to see who edited this record”, a well-designed append-only table with explicit revisions gets you 80% of the value at 20% of the operational and cognitive overhead.

Using Postgres as the event store is interesting because it pushes against the myth that you need a specialized log store from day one. But it also exposes the other myth: that event sourcing is primarily a technical choice. It isn’t. It’s a commitment to treat “how the state got here” as a first-class part of the domain, and that cultural/organizational shift is usually harder than wiring up SaveEvents and a Kafka projection.

Sure you can cherry pick an example that would be difficult for me to monetize.

However I can think of plenty I’d do with the model weights for ChatGPT, Claude or Gemini. Can’t you?

I can go on with hundreds of examples. The Waymo source and models, as another example. Enumerating everything would detract from the message so I’ll stop here.

Sure, every business owner has incentives that point to delivering a worse product (eg cheaper pizza ingredients increase margins). For most businesses there is a strong counteracting incentive to do a great job so the customer returns next week.

The key variable is how long that gap of time is. In the online dating example, if the dating app does a sufficiently great job you will never return. A milder version: if the used car salesman gives you great value, you might be back in 10 years. This creates very weak incentives for good service, so more predatory tactics dominate.

They're trying to increase their "compute capacity" over 5 years but aiming for the same cost and energy consumption. It's a drive for some buildout combined with hardware/algorithm efficiency improvements.

They're not trying to build double the data centers every 6 months. But Ars likes the "economic collapse" narrative because I guess their journalist spends too much time on social media.

If a recession comes it likely won't come from AI anyway, and anyhow nothing will happen to these huge tech companies.

Author is deluded. LLMs aren't the quiet, smart assistant. LLMs are regurtitators of "truths" they have mapped in their models. The outputs are always subtly wrong, and, at best, an average of existing outputs out there.

You will never make something completely "wow" with an LLM alone. You will spend more time debugging the output than you would have making it from scratch. And, at best - you'll end up with mediocre results, by definition.

Author needs a serious case of a holiday, rest, and mental reset.

The problem to me doesn’t seem to be the em dashes but rather the multiple people around you that actively talk about “being an intellectual writer“ and how they need to signal it with their choice of punctuation. Frankly they sound ridiculous. But again, that has nothing to do with the actual punctuation itself. Writing off a writing tool because of two people you agree are ridiculous doesn’t seem like the right way to respond to their behavior.

I’ve used it for literally decades for both formal and informal writing. On social media and in text messages. It is a very useful way to communicate/pace your sentences.

The Hidden ROI Problem with LangChain Agents

After analyzing hundreds of production agent workflows, we discovered something: 40-70% of agent tool calls and text prompts don't need expensive flagship models. Yet most implementations route everything through their selected flagship model.

Here's what that looks like in practice:

A customer support agent handling 1,000 queries/day: - Current cost: ~$225/month - Actual need: 60% could use smaller or domain specific models (faster, cheaper) - Wasted spend: $135/month per agent

A data analysis agent making 5,000 tool calls/day: - Current cost: ~$1,125/month - Actual need: 70% are simple operations - Wasted spend: $787/month

Multiply this across multiple agents, and you're looking at hundreds in unnecessary costs per month.

The root cause? Agent frameworks don't differentiate between "check database status" and "analyze complex business logic" - they treat every call the same.

The Solution: Intelligent Model Cascading

We built CascadeFlow's LangChain integration as a drop-in replacement that:

1. Tries fast, cheap models first 2. Validates response quality automatically 3. Escalates to flagship models only when needed 4. Tracks costs per query in real-time

The integration is dead simple - it works exactly like any LangChain chat model. No architecture changes. Just swap your chat model for CascadeFlow.

What you get: - Full LCEL chain support - Streaming and tool calling - LangSmith tracing out of the box - 40-85% cost reduction - 2-10x faster responses for simple queries - Zero quality loss

Real production results from teams already using it.

Is this still the case in 2025, though?

In a traditional pork cycle there's a relatively large number of players and a relatively low investment cost. The DRAM market in the 1970s and 1980s operated quite similarly: you could build a fab for a few million dollars, and it could be done by a fab which also churned out regular logic - it's how Intel got started! There were dozens of DRAM-producing companies in the US alone.

But these days the market looks completely different. The market is roughly equally divided up between SK Hynix, Micron, and Samsung. Building a fab costs billions and can easily a year of 5 - if not a decade - from start to finish. Responding to current market conditions is basically impossible, you have to plan for the market you expect years from now.

Ignoring the current AI bubble, DRAM demand has become relatively stable - and so has the price. Unless there's a good reason to believe the current buying craze will last over a decade, why would the DRAM manufacturers risk significantly changing their plans and potentially creating an oversupply in the future? It's not like the high prices are hurting them...

I dont really know what has happened, but many forces have had to improve Linux kernel incrementally. 15 years ago, linux was terrible at suspend-to-ram, wifi drivers a nightmare. Power efficiency was lagging far behind on most architectures. Everyone from intel, to amd, router vendors, server datacenters and android manufacturers have gradually improved these parts over years and years and now, there seems to be enough vested interest that linux compatibility is not a third afterthought, but having good linux support early means you can launch on a android phone, in the datacenter, or build for a custom SoC.

I've already used some "adult" exams where someone fucked up and forgot to set minimum ages and got my kids through them perfectly fine. The kids are not the problem, or at least, having them pass the normal exams at the normal age for those exams is possible. The schools simply aren't doing it.

The issue with that approach is that it's a lot of work, and I would love an alternative. But I don't have an alternative.

That doesn't follow. I could be incredibly sentimental about something and still very happily part with it for millions of dollars. You are inventing a dichotomy that doesn't exist.

Further, saying that men shouldn't have emotions, or display the same emotions, lest they be labeled "drama queens", is absolutely gross behaviour. It's one of the contributors to the male loneliness / suicide epidemic, and you really should do better.
