Let me start with noise is subjective, one person may not hear a thing and believe it to be silent whereas another may hear the exact same thing and consider it loud.

I keep seeing this question pop up over and over again then when I look in the comments there's still misinformation about side by side. Before answering some context would be helpful to understand why.

Beat frequency, an annoying periodic humming, occurs when two fans next to each other are running near the same constant speed. This happens in push-pull (radiators and cpu coolers) and SIDE-BY-SIDE (CASE FANS, radiators, etc) applications.

There is a Noctua NF-A12x25 two-pack that states the fans are +/- 50rpm to avoid beat frequency.

Why does the NF-A12x25 G2 PWM Sx2-PP have an rpm offset? The G2's have extremely precise speed control and when combined with their SupraTorque feature allowing for extra torque headroom to maintain an exact speed even when against resistance, their speeds are more likely to align together.

Also you may have seen fan specifications saying 2000 ± 10% RPM or 2000 ± 150 RPM, the fan's nominal rated speed with a tolerance. For example, sometimes when two identical fans running at 100% rpm, one may be 2000 rpm vs the other 2200 rpm. These fans have an rpm offset right out of the factory so beat frequency would be negligible. The G2's have a near 10 rpm tolerance, meaning 2000 rpm vs 2010 rpm so they are affected by beat frequency more than any other fan.

With such a tight tolerance is exactly why Noctua went with a technical solution for the G2's with an inherent rpm offset to eliminate beat frequency.

I could get a 2-pack and a single and have all three at different frequencies or just load up 3 identical fans.

A 2-pack and a single may be good enough, the single will have an 25 rpm offset compared to the others out of the box. I'd suggest keeping the PP's together like PPA-PPB-Single so at least two fans have 50 rpm offset instead of PPA-Single-PPB with 25 rpm offsets on all. If you encounter beat frequency, you can put the single on another header and introduce your own offset.

3 identical fans, especially if they're G2's may have beat frequency. If you encounter beat frequency, you could daisy chain the top and bottom together and put the middle on it's own fan header for rpm offsets.

As stated in the beginning you may not be noise sensitive and may not hear a difference. However if you are noise sensitive, 50 rpm offset may not be enough, sometimes 100 rpm or 200 rpm is required to completely eliminate beat frequency which would mean creating your own rpm offsets.

Also curious how that works as I have all three fans on a single header and use FanControl to manage it. Does the offset apply in a way that FC is not aware of or will it override that?

FanControl/Bios only sees the rpm of the one fan with the 4th pwm pin, the other two fans are slaved and do not have this pin (3 pins). The offset is inherent and will continue to have an rpm offset at all times even when daisy chained. FC is not aware of the offset at all, as stated when 3 fans daisyed together it'll report the rpm of only the fan with the 4th pwm pin.

For example, if your setup is like PPA-PPB-Single and the single has the 4th pin then FC may show 1000 rpm from the single while the PPA is at 975 rpm and PPB is at 1025 rpm. If your setup is like PPA-PPB-Single and the PPA has the 4th pin then FC may show 1000 rpm from the PPA while the PPB is at 1050 rpm and the single is at 1025 rpm.

Does Yegge really think that building production software this way is a good idea?

Let's assume that managing context well is a problem and that this kind of orchestration solves it. But I see another problem with agents:

When designing a system or a component we have ideas that form invariants. Sometimes the invariant is big, like a certain grand architecture, and sometimes it's small, like the selection of a data structure. Eventually, though, you want to add a feature that clashes with that invariant. At that point there are usually three choices:

* Don't add the feature. The invariant is a useful simplifying principle and it's more important than the feature; it will pay dividends in other ways.

* Add the feature inelegantly or inefficiently on top of the invariant. Hey, not every feature has to be elegant or efficient.

* Go back and change the invariant. You've just learnt something new that you hadn't considered and puts things in a new light, and it turns out there's a better approach.

Often, only one of these is right. Usually, one of these is very, very wrong, and with bad consequences.

But picking among them isn't a matter of context. It's a matter of judgment and the models - not the harnesses - get this judgment wrong far too often (they go with what they know - the "average" of their training - or they just don't get it). So often, in fact, that mistakes quickly accumulate and compound, and after a few bad decisions like this the codebase is unsalvageable. Today's models are just not good enough (yet) to create a complete sustainable product on their own. You just can't trust them to make wise decisions. Study after study and experiement after experiment show this.

Now, perhaps we make better judgment calls because we have context that the agent doesn't. But we can't really dump everything we know, from facts to lessons, and that pertains to every abstraction layer of the software, into documents. Even if we could, today's models couldn't handle them. So even if it is a matter of context, it is not something that can be solved with better context management. Having an audit trail is nice, but not if it's a trail of one bad decision after another.

I am not getting anything out of the meeting. I am learning nothing. Because there are no experiments, this field is not an active one, so few of the best men are doing work in it. The result is that there are hosts of dopes here and it is not good for my blood pressure: such inane things are said and seriously discussed here that I get into arguments outside the formal sessions (say, at lunch) whenever anyone asks me a question or starts to tell me about his “work” [...] There is great deal of “activity in the field” these days, but this “activity” is mainly in showing that the previous “activity” of somebody else resulted in an error or in nothing useful or in nothing promising. It is like a lot of worms trying to get out of a bottle by crawling all over each other.

Demanding everything be free and open source is important if you don't want independent developers to be able to make a living, and instead wish to create a world where the vast majority of software is controlled by big tech, who are the benefactors of "free" software. The less you're willing to pay people making good software, the more territory predatory ad/tracking-fueled "free" software gets. The more territory you give them, the more they're going to buy out open source software to destroy. We see this happening more and more recently, with uv, bun, vite etc. being bought out - if they can't put food on the table, they will sell out to monopolists.

there isn't really any "prompt engineering" involved

You should make an experiment; take someone who never used any LLMs or agents, and tell them to use it for the first time in front of you, and tell them to build something like a calculator program or whatnot. Bonus points if they're ICs or at least not-managers.

I think there is a lot us engineers take for granted, when it comes to communicating via text, how to state things clearly and what we think/reason when we read things. A lot of people don't have those "skills" innate, and the first time they use LLMs, they basically don't know how to interact with them, until they realize what they're able to do and not. Then they also learn what to say to steer the model into the right way, this is quite literally a "prompt engineering" skill they're now learning.

You don't even have to go outside engineers. I have teammates that get very little out of Claude Code because the way they integrate their own knowledge doesn't allow them to think of what Claude might not know. They'd say a task was impossible with the tooling, and I'd get instant answers, because I understand what is weird internal business logic sitting 6 repos away, and what is knowledge claude has by default. I can commit Claude.md files for them, but I have to include EVERYTHING, because otherwise they'll let Claude make assumptions and waste minutes, if not hours.

It's a big part of what, in my experience, is separating the very good engineer from the iffy one: Do you have a good mental model, and can you put yourself in the shoes of people sitting in a different mental model? It makes you a better dev, and even more so when it comes to AI tools, which have their own kind of alien brain.

Assertions detect programmer errors. Unlike operating errors, which are expected and which must be handled, assertion failures are unexpected. The only correct way to handle corrupt code is to crash. Assertions downgrade catastrophic correctness bugs into liveness bugs. Assertions are a force multiplier for discovering bugs by fuzzing.

It's not even close. The CEMU version is objectively the best way to play the game. Over any Switch emulator or the Switch 2.
All the mods (google BCML and check out gamebanana's CEMU BOTW page), graphic packs, reshade presets, the motion control support with any gamepad incl. Steam Deck, higher performance even at 4k... The ONE thing the Switch emulated version has going for it, a texture mod, is also entirely usable on PC with an unpacked game (the only caveat being some shrines may crash on load, so it's better to keep a vanilla dump for shrines if they do).

Otherwise, CEMU is so much better in every way. Switch also has mods, but they are far fewer and require more steps to set up and use BCML for.

My background is in embedded systems, specifically routers, in which bugs and unexpected operations happen from time to time, causing problems. In this environment, storage space is at a premium (most routers do not have hard drives, and only a limited amount of RAM and non-volatile flash memory), and devices are often deployed at remote sites with no operator at the console. Embedded devices are expected to function properly without human intervention, and crashes or other malfunctions are rare compared to interactive applications.

In this environment, when an error occurs, it is a good idea to record as much information as possible, because asking the operator to turn on extra event logging and then try to re-create the failure is only going to make the customer more angry ("my network has already broken once today, you want me to intentionally break it again?"). That one crash is the only chance you have to learn about the cause.

There's a huge case of survivorship bias when trying to recall historical analogues, because in every instance where margins collapsed and competition made the industry a commodity business, the big proprietary names are no longer with us. Here's a selection of examples, though:

1. Memory chip margins collapsed so much in the 80s that Intel exited the memory chip business entirely. At the time, they were known much more as a memory chip company than a microprocessor company.

2. Margins for high-end workstations collapsed in the face of cheaper IBM PC clones and an explosion of MS Windows software. This led directly to the deaths of SGI, Sun, Symbolics, Lucid, LMI, etc.

3. Proprietary UNIX variants like HP-UX, IRIX, AIX, and SCO Unix have basically completely died out, replaced by lower-cost proprietary OSes like Windows and MacOS, or by open-source descendants of Linux and BSD.

4. Many commercial database vendors like Oracle, dBase, Sybase, FoxPro, and Microsoft (SQL Server and Access) found themselves very much under margin pressure from PostGres, MySQL, and SQLite. Oracle survived thanks to their massive installed base and legal department, and Microsoft survived because they could cross-subsidize from their OS and Office monopolies, but dBase, Sybase, and FoxPro are no longer with us.

LLMs drive the unit cost of cognition to zero. Therefore, you will exhaust yourself near-instantly trying to drive differentiated value out of cognitive work. Non-arbitrable labor is one safe haven: bending steel, drilling wells, running cables, flying drones, etc. Physical agency gets you a premium the clankers can’t (yet?) trespass upon. That’s why guys building data centers are making bank & job-hopping while the SAs administering the computational guts of them are struggling. A second vector is reputational: either by authority (you’re a regulator) or by taste (you’re a rare/reknown specialist) you make quality attestations about cheaply-produced cognitive artifacts. The first vector is a big community; the second is not. Get out of being in a knife fight with the clankers on their own turf, they’ll gut you.

Why Use JetBrains Runtime?

Embedded browser: JetBrains Runtime includes the Java Chromium Embedded Framework (JCEF), which enables you to embed a Chromium-based browsers in your JVM-based application. To use it, download a build with JCEF.

Enhanced class re-definition with the DCEVM technology that makes it easier to reload changed code without restarting JVM; this feature needs to be explicitly enabled with -XX:+AllowEnhancedClassRedefinition.

Better FPS performance for graphics-intensive applications.

Improved font rendering, keyboard input (such as shortcuts and multinational keyboards), HiDPI and accessibility support.

Robust desktop experience: GUI-related fixes often reach JetBrains Runtime much earlier than the corresponding version of OpenJDK.

Additional capabilities that are made available to applications through JBR API services such as, for example, the ability to wrap a native graphics texture into java.awt.Image.

If you are truly exceptional at something, a hard truth you will face is that you can't expect the same standard of others. By definition, you are an outlier, and thus you live on an island.

Many of us struggle with this because:

(a) we wish to be optimists of our fellow man

(b) it is lonely being on an island, or

(c) we seek to be humble about our powers.

But honesty is the best policy in this case. Humility that is not truthful is more like a chain than a virtue. And you can still be optimistic about others. But not by pretending they can emulate you or touch the same bar. Rather, you can be optimistic that if you build the right bridge, they can and will cross to join you where you are.

And an even better policy? To realize that others around you are on their islands too, exceptional from you in their own ways, and ways that you may not fully realize yet. Perhaps there is a bridge or two you may cross also.

I am a very optimistic person when it comes to people's ability to grow, change and develop mastery in their field, if they really invest themselves into it. Almost to a fault :) Most of my writing and the way I choose to lead is based on that belief.

But my optimism comes with a deep appreciation for how hard it is to be truly exceptional. To become an outlier in terms of excellence. In addition to natural talent, good fortune and intent, it requires oodles of mental work and fortitude. And even if you are the rare person to reach the mountaintop, you realize you're... on an island.

It is why I believe bridge-building is an incredible skill to nurture too. In fact, perhaps we should think of this as part of what it takes to be a truly exceptional expert or leader - to bring others along too.

Yes, pleaaaaase. Apple’s modems just do not have the same performance as Qualcomm’s cellular chips. While Apple’s use less power and download/upload speeds are comparable, Apple’s chips frequently drop and regain connection while Qualcomm has been rock solid. This obviously differs a bit based on the area, but everyone in my area that has apple chips, no matter the carrier, frequently deals with random drops while people right next to them on the same carrier with Qualcomm chips don’t deal with this issue at all. At least to me, it feels almost same as the intel vs Qualcomm chips back in the day, and this same area had massive issues with anybody who had intel chips

• We've always tried to do things well at Stripe. I've come to see that attempting to do them beautifully is often a helpful way to break out of standard practices and to do something with greater novelty and in a way that might have other benefits besides. (Also, excellent people want to do great work because it is intrinsically satisfying. Explicitly allowing aesthetic considerations to carry weight avoids having to justify every assessment with some kind of torturous empiricism.)

Just a few days ago they turned on an experiment the forces claude code to use bash over standard tools in auto mode.

From the system prompt directly, new as of August 18th:

Do your work through the Bash tool wherever it can accomplish the job: read files with cat, head, or sed -n, search with grep and find, and make file changes with sed, heredocs, or short scripts, rather than using the dedicated Read, Edit, or Write tools. Fall back to a dedicated tool only when Bash genuinely cannot do the job.

I was wondering why Claude Code started ignoring my LSP tools and such a couple days ago, and this is why. Prompting around it (even with CLAUDE.md) results in low adherence. This can be turned off by setting a special environment variable (setting CLAUDE_CODE_THRIFTY_SONIC to 0), but this is just a bad idea all around.

I'm sure they'll argue they are trying to make it use less context tokens to do things, but if this is the best they could think of, ....

This is of course, also not documented anywhere, as is typical for anthropic, you just have to guess whether you are going crazy or if they changed stuff seriously on you under the covers.

When you use an LLM to author a post, you may think you are generating plausible writing, but you aren’t: to anyone who has seen even a modicum of LLM-generated content (a rapidly expanding demographic!), the LLM tells are impossible to ignore. Bluntly, your intellectual fly is open: lots of people notice — but no one is pointing it out. And the problem isn’t merely embarrassment: when you — person whose perspective I want to hear! — are obviously using an LLM to write posts for you, I don’t know what’s real and what is in fact generated fanfic. You definitely don’t sound like you, so… is the actual content real? I mean, maybe? But also maybe not. Regardless, I stop reading — and so do lots of others.
