Fish Drives Tank | Hackaday

Published

on

Fish are popular animals to keep as pets, and for good reason. They’re relatively low maintenance, relaxing to watch, and have a high aesthetic appeal. But for all their upsides, they aren’t quite as companionable as a dog or a cat. Although some fish can do limited walking or flying, these aren’t generally kept as pets and would still need considerable help navigating the terrestrial world. To that end, [Everything is Hacked] built a fish tank that allows his fish to move around on their own. We presume he’s heard the old joke about two fish in a tank. One says, “Do you know how to drive this thing?”

The first prototype of this “fish tank” is actually built on a tracked vehicle with differential steering, on which the fish tank would sit. But after building a basic, driveable machine, the realities of fish ownership set in. The fish with the smallest tank needs is a betta fish, but even that sort of fish needs much more space than would easily fit on a robotics platform. So [Everything is Hacked] set up a complete ecosystem for his new pet, making the passenger vehicle a secondary tank.

The new fish’s name is [Carrot], named after the carrots that [Everything is Hacked] used to test the computer vision system that would track the fish’s movements and use them to control the mobile fish tank. There was some configuration needed to ensure that when this feisty fish swam in circles, the tank didn’t spin around uncontrollably, but eventually he was able to get it working in an “arena” where [Carrot] could drive towards some favorite items he might like to interact with. Mostly, though, he drove his tank to investigate the other fish in the area.

The ultimate goal was for [Everything is Hacked] to take his fish on a walk, though, so he set about training [Carrot] to respond to visual cues and swim towards them. In theory, this would have allowed him to be followed by his fish tank, but a test at a local grocery did not go as smoothly as hoped. Still, it’s an interesting project that pushes the boundaries of pet ownership much like other fish-driving projects we’ve seen.

GrapheneOS takes a hard line on privacy, no ID checks anywhere

Published

on

GrapheneOS is doubling down on privacy at a time when most platforms are moving the other way. The security-focused Android alternative says it won’t require personal information from users, even as governments tighten identity and data collection rules.

In a recent public post, the team said the OS will remain usable without accounts or ID checks worldwide. That decision comes with a clear tradeoff. If local laws demand verification, access in those regions could disappear instead of the platform changing its approach

That puts GrapheneOS on a direct collision path with a broader push toward verified online services. While most companies adapt quietly to stay compliant, this project is choosing to stay outside that system entirely.

No ID means no compromise

The position itself isn’t new, but the clarity is. Access to GrapheneOS and its services won’t depend on signing up or proving your identity, regardless of where you are

Advertisement

GrapheneOS will remain usable by anyone around the world without requiring personal information, identification or an account. GrapheneOS and our services will remain available internationally. If GrapheneOS devices can’t be sold in a region due to their regulations, so be it.

— GrapheneOS (@GrapheneOS) March 20, 2026

Instead of tailoring rules for each market, the platform keeps a single global standard. If a government requires identity checks to distribute or use it, support in that region stops there.

That approach is rooted in how the OS is built. GrapheneOS strips out unnecessary data exposure wherever possible, including avoiding centralized accounts that can tie activity to a person. Adding identity requirements would break that model at a fundamental level.

Why this stance stands out

There’s a practical downside to that consistency. In regions where stricter rules take effect, users could lose access to GrapheneOS devices or updates tied to the platform

Advertisement

The limitations go further than availability. Hardware support is deliberately narrow, limited to devices that meet strict security requirements. Broader compatibility options are avoided because they weaken protections. Even setup reflects that thinking, with preloaded devices offered to reduce exposure to standard Android installs

That tradeoff is hard to ignore. You get stronger privacy guarantees, but you give up flexibility in devices and access.

What happens next

GrapheneOS is still trying to grow without loosening its rules. A long-term partnership with Motorola aims to bring official support to more devices starting in 2027, which could improve availability without lowering its standards

Expansion will stay selective. Devices that don’t meet its requirements won’t be supported, even if that slows adoption.

The project’s funding model also plays a role. It runs entirely on donations, now enough to support a full-time team. That independence gives it room to hold this line while others bend under regulatory or commercial pressure.

If you’re thinking about switching, the value is straightforward. You get a mobile OS that avoids identity checks entirely, but depending on where you live, access could become harder to maintain over time.

Better Faux-Analog VU Meters | Hackaday

Published

on

One of the coolest things about old hi-fi hardware is that it often came with flickety needles that danced with the audio level. You can still buy these if you want, or you can simulate the same look on a screen, as [mircemk] demonstrates.

It isn’t [mircemk]’s first rodeo in this regard. An earlier project involved creating simulated VU meters on round displays, but they were somewhat limited. Using the Adafruit GFX library on an ESP32 netted a working setup, but it was jerky and very jagged and digital-looking. It was more akin to a fake needle display running on an 8-bit computer than something that looked like a real vintage VU meter.

[mircemk] didn’t give up and figured the ESP32 microcontroller and GC9A01 round display could surely deliver better results. The trick was to leverage the LVGL graphics library instead, along with the Squarelinestudio UI editor.  The library was able to display far richer graphics that look like an actual vintage VU meter, even appearing glowing and backlit like the real thing. The moving needle animates far more smoothly as well, pulsing with the music in a way that feels far more realistic compared to the earlier attempt.

It’s nice to see this simple project revisited and so boldly improved just a year later. If you’re looking to implement real-looking gauges while retaining the flexibility of a small LCD screen, you might like to try the LVGL library for yourself. With that said, sometimes you just can’t beat the real analog gauges themselves. Video after the break.

OpenAI to double headcount by end of year, reports FT

Published

on

The AI company is facing strong competition from rivals such as Anthropic.

OpenAI is aiming to nearly double its headcount by the end of 2026, according to a Financial Times report.

The publication estimated that current staff numbers of 4,500 would reach around 8,000 by the end of the year, citing two people with direct knowledge of the matter, and added that the new roles would largely be across product development, engineering, research and sales.

Last month, Irish media reports suggested OpenAI was looking for a new, larger Dublin premises for its European headquarters, having established its Irish presence in 2023. Then, CEO Sam Altman said that the company chose Ireland because it “blends a talented workforce with support for innovation and responsible business growth”.

The company is currently hiring in cities in the US, Europe, Australia and Asia.

OpenAI is facing stiff competition in its field from rivals such as Anthropic, which recently announced the planned expansion of its Dublin operation and the creation of 200 new jobs by 2027 in engineering, sales, finance, legal and compliance, and operations.

As of November 2025, Anthropic had around 300,000 enterprise customers, while OpenAI had more than 1m, but recent data shows that Anthropic is now capturing more than 73pc of all spending among companies buying AI tools for the first time, while OpenAI is down to around 27pc.

Last week, reports surfaced around a planned OpenAI desktop ‘superapp’ that would combine its AI chatbot, coding tool and web browser, although no launch date was yet known.

Meanwhile, Anthropic’s chatbot Claude also overtook OpenAI’s ChatGPT as the most downloaded app in the US last month after Anthropic began engaging in a public feud with the country’s Department of Defense over AI safety concerns.

In late February, a $110bn funding round brought OpenAI’s valuation to $730bn. The round featured major contributions from Amazon, Nvidia and SoftBank – the latter of which had its outlook lowered by S&P earlier this month due to a perceived over-reliance on heavy investment in OpenAI.

In February, OpenAI hired OpenClaw founder Peter Steinberger to develop its “next generation of personal agents”, and earlier this year began implementing age-prediction for users.

Research finds AI summaries are better for learning, even if they can change your opinions

Published

on

Most of us now get our information using AI chatbots and search engines. Even Google shows us an AI summary first before guiding us towards the sources it compiled the answers from.

A new study from Yale suggests that while AI-generated answers are fast, convenient, and easy to read, they can also influence our opinions. Daniel Karell, an assistant professor of sociology at Yale, and his team wanted to find out whether reading AI-written summaries of historical events helped people learn better than reading human-written ones. 

To test this, participants were shown short summaries of historical events, some written by humans and others by AI tools like ChatGPT, and then quizzed on what they remembered.

The result? People who read AI-written summaries consistently answered more questions correctly.

Advertisement

Is AI just better at disseminating information than humans?

Karell attributes this to how AI presents information. “It’s like the model took Wikipedia and made it more readable,” he said. The AI summaries were smoother, clearer, and easier to retain, regardless of whether participants knew they were reading AI-generated content.

That means, even when people were told the summary was written by AI, they still learned more from it than from the human-written version.

Should this worry you?

Here is where it gets interesting. In a follow-up paper published in PNAS Nexus, the same researchers found that AI summaries not only teach better, but also influence political opinions.

If the AI summary had a liberal slant, readers came away with more liberal opinions. A conservative slant had the opposite effect. The researchers believe this happens because AI doesn’t just present facts, but it frames them in a way that feels more logical and convincing.

AI tools are becoming the default way people learn about history and current events. That is not necessarily bad. But knowing that the tool shaping what you learn can also quietly shape what you think is something worth keeping in mind.

At the same time, AI hallucinations remain a significant issue, and AI-generated summaries can be even more misleading for humans. A study conducted by researchers at USC’s Information Sciences Institute found that AI systems can execute propaganda campaigns with minimal human input.

If we add to this the idea that AI can be more convincing than humans, it’s scary to think how these tools can be used to manipulate human thinking and reasoning, guiding us toward a more fractured world.

Meze Astru Review: $899 Titanium Flagship IEM Takes On the Best Under $1000

Published

on

Meze Audio, founded in 2011 in Romania, has built a strong reputation in high-end personal audio with standout over ear models like the award winning Empyrean II, 109 Pro, and the recently updated 99 Classics 2nd Gen. But while the brand has become one of the more recognizable names in premium headphones, its track record with in-ear monitors has been far less consistent.

We had an early preview of the new Astru at CanJam NYC 2026, where one thing was impossible to ignore: wired IEMs are having a moment and were at the center of the conversation. If you think the category is fading in a world dominated by wireless earbuds, think again. Enthusiasts are doubling down on sound quality, and brands are responding.

The Astru is Meze’s latest attempt to finally lock in a true flagship IEM. Featuring a titanium shell and a single dynamic driver design, it builds on earlier efforts like Advar and Rai Penta, both of which showed promise but struggled to fully land with critics and buyers. The question now is simple. Can Meze translate its headphone success into the IEM space, or is this another near miss?

Key Specifications and What They Actually Mean

The Astru uses a single 10mm dynamic driver with a titanium and PEEK diaphragm, a combo designed to balance rigidity and flexibility for a more natural, controlled sound. With a 32 ohm impedance and 111dB sensitivity, it is easy to drive from a phone or dongle, but still benefits from better sources.

Advertisement

Meze includes a 0.78mm 2-pin cable with a 4.4mm balanced termination, which signals this is meant for serious portable gear, not just casual listening. At 13.4 grams with a titanium shell, it should feel solid without being fatiguing, and at $899, it lands in a very competitive tier where sound quality matters more than design alone.

meze-astru-iems-exterior

Who Astru Is For and Who It Is Not

The Astru is aimed squarely at dynamic driver enthusiasts and anyone chasing a flagship IEM experience built around Meze’s house sound. It will appeal to listeners who prioritize cohesion over complexity, delivering a unified presentation that does not sacrifice treble performance, along with a warm, balanced tuning that favors musicality over analysis.

It is not for bassheads, listeners who demand true reference sound, or those chasing maximum top of the line vocal resolution. If your priorities lean toward impact, absolute neutrality, or extracting every last micro detail from a vocal track, this may not be your endgame.

Build

Meze went with titanium for the Astru’s shells. It is an expensive, finicky material, so it makes sense that they also reduced the visual and structural complexity to match. That said, the two-tone character of models like Advar and Alba is missed. This more minimalist approach makes the Astru feel less like a statement piece and more like an unfinished Blender render than a flagship Meze IEM.

meze-astru-iems-interior

Style aside, Meze clearly put real effort into the Astru’s geometric shell design. The titanium nozzles feature precisely cut, integrated debris filters with a clean chamfer leading into a tight lip, giving the whole assembly a more refined, engineered feel.

Like the Alba and unlike the Advar, the Astru uses 0.78mm 2-pin detachable cables, with the sockets housed in smoky black plastic blocks. It works, but it is a step back visually. The Alba at least added a red accent on the right side for quick channel identification, a small but thoughtful detail that is missing here on the more expensive Astru.

meze-astru-y-splitter

The effort Meze put into the Astru’s cable is obvious, from the soft, premium feeling twisted braid to the custom cut hardware on the Y splitter, giving it a true flagship feel in hand rather than something thrown in to check a box. It uses a fixed 4.4mm termination, with a 4.4mm to 3.5mm adapter included in the box for broader compatibility.

Comfort

Comfort is always subjective and heavily dependent on your ear anatomy, so mileage will vary. The Astru is one of the most-comfortable IEMs I’ve used. I was able to listen to it without any discomfort. Its lightweight titanium shells work wonders for long transit rides and intense work sessions, though I did not get the best passive isolation with the stock eartips. 

Accessories

meze-astru-ear-tips
meze-astru-case

Inside the box you’ll find:

  • 1x Semi-hard carrying case
  • 1x 4.4mm-to-3.5mm adapter
  • 5x Pairs silicone eartips
  • 1x Synthetic leather baggie
  • 1x Metal Astru plate

Meze did well with the Astru’s cable. It feels great in hand and is comfortable to use, but the rest of the accessory package does not keep up. The carrying case uses the same overall design as previous Meze flagships, but swaps the glossy black finish for a cheaper feeling satin coating that is more prone to scratches and long term wear like drying or flaking. By comparison, my well used Advar case still looks close to new. At $100 more, this feels like a step backward in overall quality.

Thankfully, Meze has improved on their ear tip offerings since 2022. The Astru’s stock eartips are comfortable and sized-well, but don’t offer the variety and passive isolation found on the sets offered by other brands. Campfire Audio, for example, includes a wider variety on even their entry-level IEMs, including liquid-silicone and foam sets. For $900, it’s fair to expect a more-comprehensive out-of-the-box experience.

Listening

About My Preferences: This review is a subjective assessment and is therefore tinged by my personal preferences. While I try to mitigate this as much as possible during my review process, I’d be lying if I said my biases are completely erased. So for you, my readers, keep this in mind:

My ideal sound signature leans toward competent sub bass, textured mid bass, a slightly warm midrange, and extended treble, though I do have mild treble sensitivity.

Testing equipment and standards can be found here.

The Astru features a gently V-shaped sound signature. It has a warm, healthy lower register, clean upper-midrange lift, and far-extending treble. The Astru exhibits a distinct “balance-first” approach to tuning, deviating from a tonal neutral purely in pursuit of a more-organic presentation. The Astru’s warm and inviting timbre and top-notch performance, blend together to deliver a distinctly “Meze” take on a harmonically-complete version of a modern meta IEM. 

The Sweet Meze Sparkle

The Astru, with its single dynamic driver configuration, faces an uphill battle against the maelstrom of audiophile preconception. Single dynamic driver IEMs have long since been maligned as somehow inferior to alternative configurations, even if the objective measurements demonstrated otherwise. The bulk of the general enthusiast population’s disillusionment with dynamic drivers is concentrated around their treble characteristics, often described as grainy, or lacking in upper-end resolution.

Advertisement

For many poorly-implemented IEMs, that’s actually true — but that’s not the case on the entry-level Meze Alba, let alone the new Astru. The Astru exhibits the best treble performance of any single dynamic driver IEM I’ve heard, bar none. Even some multi-driver, planar-based, tribrids don’t resolve subtle textures as cleanly as the Astru does.

I was particularly taken by the Astru’s ability to resolve the tactile decay of the hi hats in “Careless” by Royal Blood (around 1:20 and 1:23). It also does an excellent job with background textures in “WANTED U” by Joji (around 3:00), integrating treble based effects naturally against the track’s dark, empty soundstage.

Meze’s focus on the Astru’s treble pays off, delivering a more elevated take on the brand’s upper register tuning. The result is a sweet, resolving timbre that avoids sharpness and sibilance, making it an easy listen even on rougher masters, including for those with mild treble sensitivity like myself.

Vivid and Lush Mids

The core trait shared between Meze’s IEMs is a lush, warm, and inviting midrange. That Meze house sound is certainly present on the Astru, as its lower-mids have a healthy dose of emphasis. They blend organically from the lower mids into the mid bass, allowing the Astru to create a strong sense of atmosphere on tracks like “Lisztomania” by Phoenix. The layering of gentle guitar strumming against punchy drums and fluttering vocals feels dynamic and engaging, exactly what you want from a flagship IEM.

The Astru’s vocal timbre benefits from its rich midrange, with male vocals sounding deep and harmonically complete. Singers with complex tones, like Chris Cornell in “You Never Really Knew My Mind,” come through with a haunting sense of weight and texture. That said, vocal intelligibility in busy tracks does not rise above what similarly priced competitors deliver.

Challenging tracks like “Letter from a Thief” by Chevelle push the Astru close to its limit in terms of vocal presence, and as a result, some of the finer edges of the performance get smoothed over. In the pursuit of maintaining a sense of vocal cohesion, Meze limited the forwardness of the Astru’s upper-mids, and this aspect of its performance is what happens as a result. 

Polite, But Firm

As divisive as bass can be, it is hard to imagine anyone putting on the Astru and not thinking this is well tuned low end. It does not lean into basshead levels of emphasis, but there is enough presence to satisfy across a wide range of genres, backed by strong control and texture rather than just quantity.

Advertisement

The Astru held its own in EDM, delivering deep, impactful bass hits in “Fat Cat Adventures” by Tut Tut Child (around 1:20). “Turbulence” by Neddie also comes through with tight, full bodied bass lines, supported by the Astru’s solid and well extended sub bass.

The Astru is just as capable with rock and alternative. It picks up even the faint mid bass drum hits in “Lydia” by Highly Suspect with ease, showing impressive control across the lower register. That control translates into strong contrast and rhythmic drive, and the Astru clearly understands that musical engagement starts with the low end.

That said, some tracks could use a bit more weight. “I Hope You Hate Me” by Dead Poet Society sounds warm enough, but the electric guitar chugs do not hit as hard as they could. The drums in “Bulletproof Heart” by My Chemical Romance are clear and distinct, but they lack the kind of physical impact you get from bassier IEMs.

Comparisons

Comparisons are chosen based on what I find most interesting. If there is something you would like to see added, feel free to drop a request in the comments.

Meze Alba

meze-astru-advar-alba-iems
Left to right: Meze Astru, Advar, Alba

The Alba is Meze’s entry-level IEM. It features slender metal shells and a single dynamic driver per-side. It sells for a fairly-affordable $159, making it significantly cheaper than the Astru’s $899 price-tag.The goal of this comparison is not to decide which one is “better,” especially given the price gap, but to highlight the differences in sound and physical design between Meze’s two newest IEMs.

For $899, Meze includes a five size set of basic silicone eartips with the Astru, while the Alba ships with a lower quality four size set. Both use detachable 2-pin cables, but the Astru’s is clearly the better execution, with a thicker build and a proper 4.4mm termination.

That said, the Alba includes a well designed USB-C DAC, which is notably absent from the Astru. Most flagship buyers will already have a capable 4.4mm source, but it still represents a meaningful loss in out of the box flexibility. The Alba also leans more into design, with a more distinctive two tone look and clearer left and right channel indicators.

Sound wise, the Alba presents hi hats and cymbals more forward, but without pushing the lower treble as prominently as the Astru. The Astru comes across warmer overall, with a fuller lower midrange and a more grounded presentation.

Bass is where the gap becomes more obvious. The Alba is lighter and less controlled, while the Astru delivers greater impact and definition. Resolution is also improved on the Astru from top to bottom, especially in how it handles hi hat decay in busy passages. That makes it the better pick for bass heavy music, though the Alba still holds its own, with a tuning that stays close enough to make switching between them feel natural rather than jarring.

All things being equal, I’d say that the Astru, on tonal merits alone, is my choice. The Alba is an excellent “baby Astru,” but doesn’t deliver the depth and lower-register technicality that I’m looking for in electronic music. Even if both IEMs shared identical physical design and price tags, I’d lean the same way.

Meze Advar

meze-astru-advar-alba-iems-cable
Left to right: Meze Astru, Advar, Alba

The Advar is the direct ancestor of the Astru, acting as the Meze IEM flagship back from 2022 until the end of 2024. Meze came back with the Astru, swapping to monochrome titanium shells and dropping much of the Advar’s visual flare. The Advar is a little weightier than the Astru, and looks quite a bit more stately thanks to its high-contrast design. The Astru uses the more-widespread 2-pin standard for its cables, rather than MMCX, which should allow users to more-easily swap to aftermarket cables.

The Astru’s cable is thicker, softer, and less tangle-prone that the Advar’s cable, which is a major quality-of-life improvement. Beyond the improved ergonomic utility, the Astru’s cable is outright nicer to look at and better-feeling in the hand. While some users may find that the decision to move to a fixed 4.4mm termination is kind of annoying, you can always swap the cable or make use of the included 4.4mm-to-3.5mm adapter to compensate. 

meze-astru-advar-cases

The Astru includes a better selection of eartips and a nicer cable, but it loses ground with the case. Instead of the more premium finish used on the Advar, you get a matte slate colored version with the same shape but a less refined look and feel.

Advertisement

Sonically, the Advar is fairly similar to the Astru, offering a broadly V-shaped sound signature with a warm lower midrange and enhanced upper-treble. The Advar, however, has less bass emphasis. The Astru, while bassier on the whole, also exhibits a tangibly-improved level of control over its mid and sub-bass, leading to an obviously-better experience with bass-centric tracks.

The intro of “Reminder” by Uppermost sounds noticeably more dynamic on the Astru, with tighter sub bass hits and improved texture throughout.

The Astru also features a retuned treble with reduced peakiness and greater overall resolution. There are plenty of treble-heavy elements on the Advar that can come across as too aggressive. The Astru is not exactly laid back up top, but it avoids that sharp edge and sounds more controlled by comparison. The Astru also demonstrates a greater degree of control over percussion decay. Hi hats and cymbals decay for longer and with a greater sense of identity on the Astru versus the Advar.

For me, the choice between the Advar and Astru is straightforward: the Astru simply sounds better. It costs more and comes with a less appealing case, but where it matters most, its musical performance is clearly superior.

Campfire Audio Alien Brain

campfire-alien-brain-iem-pen

The Alien Brain is a $1,000 IEM from Campfire Audio. It features a selection of balanced-armature and dynamic drivers per side and uses a combination of aluminum and plastic for its shells. Coming in at $100 more than the Astru, the Alien Brain features a simple carrying case with a magnetic flap and a pair of flat-braid MMCX cables. The Alien Brain includes a USB-C DAC, which is a utility absent from the Astru’s accessory package. The Astru has a less-robust selection of eartips in the box, notably missing the liquid-silicone and foam varieties found in the Alien Brain’s eartip suite. Campfire Audio also includes a number of tertiary goodies that Meze does not, including a microfiber cleaning cloth, cleaning tool, protective IEM baggie, and lapel pin. And while these are not essential to the core task of listening to music, the level of detail and finish from Campfire Audio feels more in line with a $900 to $1000 experience than what Meze delivers with the Astru.

Sound wise, the Alien Brain leans more into upper treble, with a more forward vocal presentation and punchier mid-bass. The Astru shifts focus slightly lower, with more forward sub bass that lets it dig deeper on drier tracks. The Astru has a warmer, more relaxed lower-midrange, giving it a comforting disposition that contrasts the Alien Brain’s more-analytical timbre. The Alien Brain, though a bit thinner-sounding, has a smoother upper-treble timbre. The Alien Brain’s cooler, more-technical presentation is a lot closer to the tonality you’d get from a classically V-shaped IEM. Its punchier mid-bass, but less-rumble-prone sub-bass, is more immediately-engaging in rock and alternative, though by a slim margin.

Fundamentally, I believe these two IEMs target different audiences. The Meze house sound, imbued into the Astru’s drivers, delivers a warm, moderately V-shaped sound signature with an emphasis on being welcoming and sweet. While I do enjoy the Alien Brain’s stronger vocal intelligibility on select tracks, that’s not enough of a benefit to entirely pull me away from the Astru’s excellent overall timbre. Given the Astru’s lower price tag, I’m gonna have to call a subjective draw between these two well-made IEMs.

Meze Audio Astru IEM Kit

The Bottom Line

The Meze Astru gets the important things right. It delivers a cohesive, natural sound with excellent treble control, strong bass texture, and a presentation that feels more refined than past Meze IEM efforts. It is easily the brand’s most convincing in ear to date and a clear step up from models like Advar, especially in resolution and overall balance.

It is not perfect. The accessory package feels uneven for the price, with a noticeable drop in case quality and a lack of extras like a bundled DAC that some competitors include. And while the tuning is engaging and musical, it is not built for bassheads or listeners chasing strict reference neutrality or maximum vocal detail.

Advertisement

Against competitors in the $900 to $1000 range, the Astru holds its ground on sound quality but gives up some points on perceived value and finishing touches. This is for listeners who want a flagship-leaning dynamic driver IEM with a warm, cohesive tuning and fatigue free treble, not those looking for the most analytical or feature packed option in the category.

Pros:

  • Ergonomic titanium shells
  • Mature, gently V-shaped sound signature
  • Precise and cohesive timbre
  • Tight bass response
  • Expressive, sweetly-toned treble
  • Excellent vocal intelligibility
  • Strong micro-detail capture

Cons:

  • Stock eartips offer mediocre passive isolation

Elon Musk is building a TeraFab chip factory, and it’s unlike anything in the world

Published

on

Elon Musk stated that every chip he can buy today only covers about 2% of what his companies actually need. Rather than wait for the rest of the world to catch up, he announced TeraFab on Saturday night, a chip factory in Austin and a joint venture between Tesla and SpaceX.

The announcement came via a livestream broadcast from the old Seaholm Power Plant in downtown Austin. “We either build the TeraFab, or we don’t have the chips, and we need the chips, so we’re going to build the TeraFab,” Musk said. The facility will be built on the Tesla campus in eastern Travis County.

Why is this announcement such a big deal?

What makes TeraFab different from existing chip manufacturers is its layout. The entire process, from creating lithography masks and making logic and memory chips to packaging and testing, will all take place under a single roof. Musk claims this doesn’t exist anywhere else in the world right now.

The advantage is a rapid design loop. “I can’t emphasize enough the importance of being able to make a chip, test it, and then change the design, do another one, and have that in a single building,” he said, adding that this approach could make their chip improvement cycle “an order of magnitude better than anything else in the world.”

What chips will the company actually make?

TeraFab will produce two types of chips. The first is optimized for edge inference, designed for Tesla cars and Optimus humanoid robots. On the scale of demand for the first chip alone, Musk was blunt and said, “I expect humanoid robot production to be somewhere between a billion and 10 billion units a year. So that’s a lot.”

The second is hardened for the space environment, built to handle the radiation and high-energy ions that would destroy conventional chips. Musk also confirmed that Tesla, SpaceX, and xAI will continue buying chips from TSMC, Samsung, and Micron, and said he’d like them to expand as fast as they possibly can. 

Cool idea, but what’s the timeline??

Honestly, what Musk showed in the livestream is genuinely exciting. The idea of pushing the limits of chip physics, trying unconventional designs, and iterating on them faster than anyone else in the world is the kind of ambition that could change things. 

That said, no timeline was given for when TeraFab will begin producing chips. And given that Tesla announced the Roadster over a decade ago and it still hasn’t shipped, I’ll reserve my excitement until the first chip rolls off the line.

‘Jury Duty Presents: Company Retreat’ Almost Makes Corporate Culture Seem Fun

Published

on

Anthony Norman is your typical Gen Z worker: 25, a little wayward, and struggling to find a full time job.

You can’t exactly fault him for the position he’s in. Unemployment rates are high. AI is creating a crisis for young people trying to enter the workforce. Hiring has slowed. And several companies—including Amazon, Block, and Meta—have embraced tech’s latest era of layoffmaxxing, with some cutting their staff by 20 percent.

So when Anthony lands a temp position at Rockin’ Grandma’s Hot Sauce, a small business in Southern California, he’s just happy for what he assumes is a regular gig: assisting with odd jobs and helping plan the annual retreat.

What Anthony doesn’t know is that he is actually the mark of Jury Duty Presents: Company Retreat, the second season of Prime Video’s experimental docu-comedy where one person unwittingly participates in a staged sitcom (the first season, which blew up on TikTok and snagged three Emmy nominations, was about a fake jury trial). Everyone is an actor except for him.

Anthony joins the team during a moment of transition. The founder, Doug Womack, is preparing to step down. His son, Dougie Jr, is next in line, and because not everyone thinks he’s fit to run the family business, he wants to prove that he’s more than an unqualified nepo baby—“the Bronny of hot sauce,” he says. Having just returned from a four-year stint in Jamaica “jamming” with a hotel lobby ska band called the Jive Prophets, the retreat is meant to be a test for Dougie Jr.

The season trades in the monotony of cubicles and watercooler talk for Oak Canyon Ranch, a cozy resort and recreation center nestled in the grassy suburb of Agoura Hills—about an hour drive northwest of Los Angeles—where the staff convenes for various activities: team building, a client cookout, motivational speakers, and a talent contest. Desperate for “one week without Cocomelon” and her three kids, Jackie Angela Griffin, the distribution and logistics rep, is ready to get away.

Like all offices, Rockin’ Grandma’s is a circus of eccentricity and ego. Accountant and bourbon enthusiast Helen Schaffer has been “cooking the books for 26 years.” Receptionist PJ Green has dreams of being a snack influencer. Sourcing manager Anthony Gwinn, who at one point confuses a flesh light for a water thermos, is jokingly nicknamed “Other Anthony” despite working at the company longer. Kevin Gomez, head of HR, has flashes of Michael Scott: He’s an overeager, comically delusional, hopeless romantic who loves his job and Amy Patterson, the customer relations coordinator. “Hot Sauce is having a moment,” he tells Anthony during the onboarding process. “You don’t see this kind of thing happening with ketchup.”

On day two, eager to demonstrate his instincts as CEO, Dougie Jr. calls an audible and brings in an “emotions and vulnerability expert”—she’s the Walmart version of academic Brené Brown—who confusingly leads the group through a conversation on how to navigate uncomfortable scenarios.

It’s good practice for Kevin’s failed proposal to Amy—they’ve actually never been on a real date minus her birthday, which included eight of her other girlfriends. After a humiliated Kevin makes a quick exit from the retreat center, to the sound of tin cans rattling as he speeds off in his car, Anthony is forced to step up.

“I got a promotion,” he says, improvising on the fly to lift morale and take on the role of “Captain Fun.”

Even as people have struggled to find meaning in their work—or simply find work—TV’s fixation with the American workplace has always been popular with viewers. Mad Men examined the existential toils of advertising executives. Severance has contemplated autonomy, in addition to a lot of other very weird shit. And no series has explored the delightful chaos of workplace hijinks better than NBC’s The Office, which followed the oddball staff of Dunder Mifflin, a Pennsylvania paper company.
