A 9-year-old Minecraft player called MightyMikePLays67 unknowingly spent a massive $118,000 on their dad’s company credit card to promote their YouTube channel. The father, Dave, gave a lengthy update on the YouTube channel, saying he’s lost his job and has to pay the amount within 30 days.

Interestingly, he’s had no issues with losing work, saying that “jobs come and go. I’ve worked my whole life; I’ll find another job… I’ve got two hands, I’m healthy, I’m capable of working. So, if losing my job was the worst that came out of this, I’d honestly probably be okay.” Unfortunately, he’s still on the hook for the massive bill, and it's gotten to the point where he and his wife are talking about selling their home to help pay for it.

Despite the depressing development, Dave and Mike were still about to joke around a bit about it. After Dave thanked his son for bringing him some water, Mike answered, “67.” He then asked, “Mike, do you even know what 67 means?”

To which the kid replied, “To say the least, I do not know what it means, but I think it doesn’t mean anything. It’s just something that makes people laugh and smile.”

The dad then replied, “Yeah, I would have to agree with that, Mike. Actually, I know what 67 means, Mike. That’s how old you’re going to be when you finally have to stop mowing lawns… That’s retirement age for the general public, but not for your old man. After this situation, apparently, I’m going to be working until I’m like 94.”

Interestingly, Dave said that he doesn’t want to accept external help, like setting up a GoFundMe or a crypto coin to help with the bill. “We do not have a Mighty Mike coin. We don’t have a 67 coin. We don’t have any coins. No crypto. We don’t have a GoFundMe. We have no fund raising set up.”

He set up a merch website with 14 different shirt designs that remind people of Mighty Mike’s misadventures, but only three designs are currently available.

A few comments said that this was a scam or a made-up story, but Dave shared a screenshot of the credit card bill (which was eventually removed) showing the $118,479.83 bill on the American Express Business Gold Rewards Card.

Several others encouraged him to take the help being offered and let big news channels talk to him, but he seems to want to deal with the problem on his own. “So, I felt like if I sit down with Fox or CNN or whatever, and I tell them my story, what has that changed?” Dave said during the YouTube video. “I’m still living in this reality, and I still have to sort of dig myself out of this hole. I don’t know if I have the mental bandwidth to sit there and talk to some reporter, but I might, anyway.”

The number 1,000 is a benchmark goal in many disciplines. You know a car is special when it has 1,000 horsepower. An amplifier reaches a different level when it can output 1,000 watts. In computer monitor parlance, 1,000 Hz or 1 kHz is also a plateau. Remember that TVs and most displays max out at 60 Hz. But the best gaming monitors, in pursuit of higher frame rates and smoother motion, have been getting faster with each new generation.

I’ve reviewed several 500 Hz monitors, mostly LCDs, with a few OLEDs sprinkled in. But currently on my desk is Acer’s Nitro XV273U F5, which has a 1,000 Hz mode. And before I get to the caveat, know that it can refresh its screen at 540 Hz in QHD 2560x1440 resolution, so even without trickery, it’s one of the fastest flat panels you can buy. This 27-inch IPS display also features Adaptive-Sync, HDR 600, and wide gamut color. Let’s take a look.

Acer Nitro XV273U F5 Specs

So, let’s get the caveat out of the way first. The XV273U F5’s 1,000 Hz mode happens at 1280x720 resolution. That’s HD, not Full HD, which is 1920x1080. The good part is that this is a multiple of QHD’s 2560x1440. The picture becomes softer but not by as much as you’d expect. Additional video processing features include backlight strobe-based blur reduction and very precise overdrive.

The XV273U F5 also provides excellent image quality from an IPS panel, which has far higher contrast than its claimed 1,000:1 ratio. I measured just over 2,000:1 in testing, which blows away most other IPS panels for dynamic range. The black levels are almost in VA territory, resulting in a very deep, textural image. Acer gets color and gamma right as well, and with a few tweaks that I’ll show you on page four, you can enjoy reference-level accuracy. Gamut coverage is generous, with around 90% coverage of DCI-P3.

The XV273U F5 is fully ready for gaming on PC or console and has all the features to enhance gameplay at any skill level. You get plenty of aiming points and sniper modes, along with a set of timers. The overdrive and backlight strobe are enabled when your system can’t push the frame rates to 540 or 1,000, and they work extremely well, with significant blur reduction and no ghosting or phasing artifacts.

Style is not forgotten here, with a rare white aesthetic. Everything is white, including the base and the included cables. Only the thin screen bezel is black. A handy joystick controls most functions, and there are three control keys, one of which switches the refresh modes.

Connectivity includes two DisplayPorts and two HDMIs. There are no USB ports. You also get internal speakers and a headphone jack. And the ports all face backward for easy access.

The XV273U F5 isn’t a trifling purchase at $700, but if you want a 1,000 Hz monitor, they aren’t exactly common. I’m anxious to pop the hood, then take it for a spin.

Assembly and Accessories

The XV273U F5 comes simply packaged in recyclable pulp forms. A clamshell box opens to reveal four parts: the panel, upright, base, and a snap-on fulcrum. You would omit that if you wanted to use the 100mm VESA mount with an aftermarket arm or wall bracket. The cable bundle includes a white external power brick and an HDMI cable, no DisplayPort though.

Product 360

There’s something cool about white monitors, mostly because they are few and far between. The XV273U F5 has a nice aesthetic that balances purpose between gaming and productivity. The angular bits are reserved for the stand. The base is a metal plate with downturned corners, finished in a white powder coat. The upright has a cable hole and a few small trim pieces, with a tripod socket at the top. It features full ergonomics with a 5.9-inch height adjustment, 5/25 degree tilt, 20-degree swivel, and a 90-degree portrait mode. Movements are firm, but there’s a little play at the fulcrum point. Getting the panel level takes a bit more effort.

In the back is a large gray Nitro logo and a smooth panel shape with no angles or extra curves. The inputs face backward, making them easy to see and access. You get two DisplayPort 1.4, two HDMI 2.1, and a 3.5mm headphone jack. There are no USB ports, but there is a pair of two-watt internal speakers that play clean and politely in the upper midrange frequencies.

OSD Features

The XV273U F5’s OSD will be familiar to users of Acer monitors. It’s divided into four fields forming a logical tree and has eight sub-sections. To summon it, press the joystick twice.

The first two menus are the gaming aids and video processing options. Enhancements include timers, aiming points in multiple shapes and colors, and a sniper mode. The reticle can be moved around the screen if you wish. The sniper scope has three magnifications and night vision. Video processing includes a frame counter, blur reduction with four backlight strobe pulse width levels, and a two-level overdrive. Both are very effective at reducing blur and operate artifact-free. The strobe is one of the very best I’ve seen. At its most extreme setting, it reduces light output by around 40%, but you can increase the brightness slider to compensate.

The picture menu includes the HDR modes. You get two: Auto and HDR 600. You would think they are different, but in my tests they measured the same. I noted that the XV273U F5 does not switch to HDR mode automatically; you must select one of these options after applying the signal. Also important in the menu is Max Brightness. Turn it on to get, you know…

In the Color menu are the eight picture modes arranged by game type or task. Standard is the default, but if you change any setting, the XV273U F5 switches to User. Calibration controls include seven color space options; Native is the most colorful, plus gamma and color temp presets. The RGB sliders include gain and bias adjustments for very precise grayscale tracking.

If you’re looking for the frame rate switch, it’s in the System menu, which is counterintuitive. It should be in the Gaming menu. You can also do it with the far-left control key to switch refresh rates without going into the OSD. Like most dual-mode monitors, you must initially set up each resolution in the Nvidia or AMD control panel. Then, you can make the switch on the fly. When you’ve made your settings, you can save them to the two memory locations under Save Settings to…

Acer Nitro XV273U F5 Calibration Settings

The XV273U F5 comes out of the box looking a little cool. It could probably satisfy most users, but a grayscale calibration takes it to reference level. The Native color gamut covers about 90% of DCI-P3, and an sRGB option is available. In all cases, gamma was spot-on, so I left that preset on 2.2. I had to reduce contrast by two clicks to solve a clipping issue. My suggested settings are below. For HDR, apply the signal first, then choose either Auto or HDR 600 from the Picture menu. And don’t forget to turn on Max Brightness for the XV273U F5’s max brightness.

Gaming and Hands-on

If you are a gamer looking for maximum smoothness and next-to-no input lag, and you don’t want to buy an OLED, the XV273U F5 is easily the next best thing. My perspective comes from the fact that the most prolific OLED category right now is 27-inch QHD 240 Hz. The XV273U F5 has the same size and pixel density, as well as excellent contrast and color. And it’s as smooth as a QHD 240 Hz OLED, albeit running at 540 Hz. I could do this without any problem using a GeForce RTX 4090, though given the fan noise I heard, it was working for it. But this monitor is the first LCD I would compare to an OLED for gaming feel and addictive play.

Motion blur simply did not exist at 540 Hz, and perceptually, neither did input lag. Turn-and-fire and circle strafe maneuvers were super easy and precise. I experienced very little wasted ammo. Competitive gamers will be right at home playing on an XV273U F5.

At 1,000 Hz, the story is different, but not that different. Yes, the picture is soft. It’s a bit like watching old TV shows on YouTube. You don’t enjoy them less, but by modern FHD and UHD standards, 480p is so 10 years ago. However, 1,000 fps is really something. The RTX 4090 worked even harder than before, but it managed to keep the frame rate locked at 1K. Again, there is no input lag, nor is there any blur. And even though the picture was soft, gameplay was just as addictive. It’s just so quick that some scenarios become too easy. For gamers of all skill levels, the XV273U F5 is a weapon.

I’m spoiled by OLEDs, so I won’t pretend that the XV273U F5 looks as good as them. But it’s closer to that standard than many other LCDs. It has one of the highest-contrast IPS panels I’ve seen, with a native contrast ratio around 2,000:1. That’s almost VA territory, but with better viewing angles and more saturated color. You’ll see in my test results on page four that this is a very accurate display, and it shows in practice. I noted that HDR content looked very good but had no more contrast than SDR. But with excellent luminance tracking and rich color, it provided decent impact.

For daily use, you can save a little power and run it at 120 Hz for productivity. That will get you smooth scrolling for webpages and documents. 109ppi pixel density gave me clear fonts, sharp graphics, and solid detail in small objects like icons and toolbars. Color accuracy and a useful sRGB mode provided good functionality in Photoshop.

I enjoyed the styling very much too, especially the white part. I’m a fan of white monitors, and the XV273U F5 is one of the nicer ones I’ve experienced. The rear-facing ports are super handy because they’re easy to see and reach. I’d have liked some USB ports, though. But I was glad to hear decent sound from the internal speakers. They aren’t Wilson Sashas, but they play clean and loud enough for one user.

Takeaway: The XV273U F5 is a superb gaming monitor with a gaming feel and response time on par with any OLED display. It has plenty of contrast and color too, which gives the picture impact and texture. I really enjoyed the styling and the white aesthetic. Though premium-priced, it can refresh at 1,000 Hz, and that is something rare indeed.

To compare the XV273U F5’s performance, I’ve rounded up a group of speedy LCDs that refresh between 210 and 360 Hz. Obviously, the response and lag tests give the Acer an unfair advantage, but I haven’t reviewed a 500 Hz LCD monitor in quite a while. They are Acer’s XB273U F5, KTC’s M27T6S and H27E6, AOC’s CQ27G4ZH, and HP’s Omen 27qs.

Pixel Response and Input Lag

Click here to read up on our pixel response and input lag testing procedures.

For the response test, only the XB273U F5 and M27T6S have been measured by my new LDAT sensor from Nvidia. Interestingly, the 360 Hz screen is the quickest at 2.4ms. The XV273U F5 seems a tad slow by comparison, and there’s only a slight difference at 1,000 Hz. But this doesn’t account for the quality of the overdrive. The XV273U F5 has one of the best I’ve seen, and it removes almost all motion blur at 540 and 1,000 Hz. It’s effective at lower frame rates too. You can run down to about 300fps before blur becomes noticeable.

The lag test is where the XV273U F5 really shines. It’s one of the quickest LCDs I’ve tested at just 14.4ms for 540 Hz and 11.1ms for 1,000 Hz. In practice, any of these monitors will satisfy twitchy gameplay, but the XV273U F5 is firmly on top. Only the XB273U F5 and M27T6S come close.

Test Takeaway: The XV273U F5 is one of the fastest LCDs you can buy. At 540 Hz, it equals many OLEDs in smoothness. The overdrive and backlight strobe are among the best available, with effective blur reduction and no ghosting or phasing artifacts. At 1,000 Hz, motion is uncannily smooth, and though resolution is reduced, it isn’t as soft as you might expect. And it has very low input lag in that mode.

Viewing Angles

The XV273U F5 is one of the better IPS screens I’ve photographed. In the side view, there is a slight blue tint but no change to gamma or brightness. The top view darkens by around 50% and has a red tint, but its gamma is better than most. This is one of the most shareable LCDs I’ve seen.

Screen Uniformity

To learn how we measure screen uniformity, click here.

The XV273U F5’s screen uniformity is also on par with many OLEDs. 5.56% is well below the point where you would see any glow or bleed. Color fields were perfectly uniform in my tests as well. This is excellent performance.

Uncalibrated – Maximum Backlight Level

The XV273U F5 has more than enough light output for any indoor space. You could use it in an outdoor location, too, with almost 500 nits available. What’s truly amazing though, is the black level. I was almost fooled into thinking it was a VA panel with a contrast ratio of 2,003:1. This is twice the IPS average of 1,000:1. Only the AOC, which actually is VA, can do better.

After Calibration to 200 nits

During calibration, I had to lower the contrast slider a bit to solve a clipping issue, but that didn’t make much difference in dynamic range. It’s still an excellent 1,937.2:1, well ahead of the next best KTC. The ANSI score is even more impressive at 1,938:1. It’s rare that any monitor matches its static and intra-image results in my tests. This is excellent performance.

Test Takeaway: The XV273U F5 tries hard to be an OLED with its superb contrast and deep black levels. It’s bright when needed as well, with nearly 500 nits of peak output for SDR content. It also shows excellent quality control with near-identical static and ANSI contrast numbers.

The XV273U F5 ships in its Standard picture mode and includes plenty of picture options like gamma presets, color temps, RGB sliders with two-point control and a gamut selector.

Grayscale and Gamma Tracking

Our grayscale and gamma tests use Calman calibration software from Portrait Displays. We describe our grayscale and gamma tests in detail here.

The initial grayscale run shows visible errors starting at the 50% brightness step. The pattern looks a little cool in tone though it’s not too far off the mark. I would definitely calibrate, but many users will be satisfied with the image. And that’s largely because gamma is within a hair of perfect. Only the tiniest dip happens at 90%, and that is well below the visible threshold. Gamma this good makes the image more textural and realistic. It also increases perceived color saturation.

Calibration takes the XV273U F5 to reference level. All errors are under 1dE except 100%, which just cracks the line. It doesn’t get much better than this. Gamma improves a tad as well, with that 90% dip almost gone. This is excellent performance.

Picking the sRGB color space grays out all other calibration controls, so you get great gamma, but that cool grayscale returns. It’s not a big deal, but I'd like the RGB sliders available. This is decent performance.

Comparisons

The XV273U F5 finishes fourth in the comparison and just cracks the “should calibrate” line. Most users will be satisfied with the picture, but since a few adjustments can produce reference-quality results, it’s worth a little effort. That takes the average error down to 0.67dE, which is awesome but not quite as good as its predecessor, the XB273U F5, or the HP.

The gamma value range is about as tight as it gets, though the AOC is 0.01 better. But when compared to the 2.2 reference, the XV273U F5 comes out on top with just a 0.45% deviation. The actual value is 2.19. The XV273U F5 has gamma on par with the most accurate pro monitors I’ve reviewed.

Color Gamut Accuracy

Our color gamut and volume testing use Portrait Displays’ Calman software. For details on our color gamut testing and volume calculations, click here.

The XV273U F5’s initial color measurement is good, but there is room for improvement. Saturation levels are spot-on thanks to the near-perfect gamma, but hues are slightly off due to grayscale errors. You can see what I mean in the next chart where my grayscale calibration has been done. Now, every point is either inside or in contact with its target box. It doesn’t get much better than that.

The sRGB mode is quite close to the mark, with a slightly warm grayscale but perfect gamma. There are slight hue errors in cyan and magenta, but other colors are spot-on. If the RGB sliders were available in sRGB mode, this chart could be improved, though it is already good enough for color-important applications.

Comparisons

The XV273U F5 has superb color accuracy and gamut coverage, with only minor errors that won’t diminish the picture. A 1.40dE final color score is among the best I’ve recorded. In the gamut volume test, it achieves 89.16% DCI-P3 coverage, which is about average for non-Quantum Dot LCD panels. It only comes up a tad short in the green primary. sRGB coverage comes close to 102% thanks to a little bonus red.

Test Takeaway: The XV273U F5 has excellent color accuracy once calibrated. Out of the box, it’s still solid. In either case, it has gamma tracking on par with the best professional monitors. Color coverage is about average for non-Quantum Dot screens with around 90% of DCI-P3. That suits it well for HDR material.

Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.

The XV273U F5 accepts HDR10 signals with a manual switch. You must apply the signal first, then choose one of the two HDR picture modes, Auto or HDR 600.

HDR Brightness and Contrast

I measured the same peak output in both HDR modes, Auto and HDR 600. The XV273U F5 just cracks the 600-nit mark, earning its VESA Display HDR 600 certification. There is no dimming, either field or zone, to reduce the black level, so contrast is the same as SDR, 1,983:1. This is solid performance, but the HP, KTC, and AOC use dimming to lower their black levels and increase dynamic range, which ultimately provides more impact.

Grayscale, EOTF and Color

The XV273U F5 has a slightly cool grayscale in HDR mode, with errors visible from the 25% step and brighter. This flattens the image a little, but that is mitigated by excellent EOTF tracking. Aside from a light 0% reading, the measurements stick close to the reference line and hit the correct tone map transition point at 65%. This is where it should be for the measured black and white thresholds.

In the color test, you can see some oversaturation in red and blue while green is close to its targets. That primary comes up a tad short at 100%, which was also the case in my SDR tests. You’ll need Quantum Dots or a Tandem OLED to get more green than this. Hues are true for all colors except magenta and cyan, which are pulled off target by the cool grayscale. In the BT.2020 test, color runs out at 85% red, 70% green, and 95% blue.

Test Takeaway: The XV273U F5 has solid HDR contrast but gives away some performance to other monitors that have zone or field dimming. It mitigates this somewhat with very accurate EOTF tracking. Color is also close to the mark and there’s plenty of saturation there to provide decent impact for HDR content.

There’s no question that OLED gaming monitors have raised the bar for motion quality, gaming feel and quick response. But LCD isn’t done yet. With a high refresh rate and good video processing, an IPS panel can provide the same experience. Acer has clearly raised the bar with its Nitro XV273U F5.

At 540 Hz, the XV273U F5 has no visible motion blur. At lower refresh rates, the overdrive keeps motion smooth and if you want a backlight strobe, it’s available and is one of the best implementations out there. You can run this monitor with any gaming PC or console. It isn’t limited to just expensive video cards. And it’s super cool to see “1000” displayed on the screen’s frame counter.

The XV273U F5 panel also provides superb contrast. Though it isn’t going to displace OLED or VA in the black level contest, I measured a 2,000:1 ratio, which puts it well ahead of the IPS average. I also measured perfect gamma, which resulted in a highly textured image with vivid color saturation and 90% DCI-P3 coverage. It can be enjoyed without calibration, but a few tweaks of the RGB sliders put it in pro-monitor territory.

I also enjoyed the white aesthetic, mainly because it’s something different. It stands out from the sea of black monitors in a good way. The only misses for me were the lack of USB ports and the lack of dimming to increase HDR contrast. But neither of these things diminishes its gaming prowess. It’s addictive in every respect.

If you want the smoothest motion and the quickest response from your next gaming monitor, and you don’t want an OLED, the Acer Nitro XV273U F5 deserves serious consideration. Definitely check it out.

A team of researchers at Maynooth University, Ireland, has created a “first-of-its-kind” DNA molecular computer that uses DNA strands to perform complex mathematical operations without electricity. Detailed in the journal Nature on September 16, the system — called a Scaffolded DNA Computer (SDC) — is one of the most complex and fastest molecular computers, and “points to new possibilities for long-term data storage, energy-efficient computation and, in time, molecular systems that could operate inside cells for applications such as disease detection,” according to the researchers. The system successfully executed 10 different molecular programs, including complex 100-bit calculations.

The researchers designed the computer via a technique known as DNA origami. Using specialized software, they mapped out a long primary DNA strand and hundreds of shorter, custom-synthesized “staple” strands. They then added the physical DNA strands to a test tube containing a drop of water and salt. When they heated and then cooled the mixture, the strands self-assembled into a highly organized, microscopic computing grid, with the long strand acting as a structural scaffold.

Traditional silicon computers use transistors to switch electrical voltages between 1 and 0. On the other hand, the molecular computer uses the binding and unbinding of genetic base pairs (A, T, C, and G) to process information. The researchers write the program into the DNA sequences themselves before putting them into the test tube and applying heat. The thermal energy kick-starts chemical reactions, causing the DNA strands to rearrange. As the molecules naturally shift toward their most stable structural state, they mathematically solve the programmed algorithm, with the final structure representing the mathematical answer.

The researchers ran 10 different molecular programs to test the system. The DNA computer successfully performed addition, subtraction, multiplication, and division. It successfully processed 100-bit calculations, proving it could handle complex data reliably without errors. Because the system is constrained by the laws of physics, it removes the need for error-correction software. More importantly, the computing requires zero electricity as the computer runs on chemical reactions. This could have huge potential for the future of computing, particularly in the researchers’ home country, Ireland, where data centers consumed 23% of the country's electricity in 2025

It's been quite a week over on Tom's Hardware Premium: let's go through all of the articles that we've published throughout this week so far.

Kicking things off with a bang, Valve officially released the Steam Frame, its latest VR headset, which adds functionality that allows the headset to act as both a standalone and PC VR headset. Our VR expert Brandon Hill reviewed the headset itself and managed to interview the engineers at Valve about their efforts on the new hardware and the software powering the company's next generation of Virtual Reality.

• Valve Steam Frame interview — why it costs up to $1,300, Snapdragon power, and 10x foveated streaming

Reporter Chris Stokel-Walker investigated the deepening DRAM and NAND crisis, honing in on how SLC and NOR Flash are the next products that have been affected by the ongoing demand for AI. Featuring expert interviews and a grim outlook on the electronics the world relies on, he explored how the ongoing data center gold rush is leaving other supply chains decimated in its wake.

Next up, AI leaders butted heads this week over alleged safety concerns about new, advanced models. It all started with one ex-OpenAI and Anthropic worker warning that the technology could endanger human existence and 'kill us all' by 2030. In response, AI leaders like Dario Amodei and Sam Altman have committed to delivering safe AI and 'pacing the frontier' of AI development, while figureheads like Mark Zuckerberg and Jensen Huang argue against the claim that AI models would do such drastic things, so long as they are developed responsibly.

A PC enthusiast has showcased their new all-AMD build on social media, packing a Ryzen 7 9800X3D and Radeon RX 9070 XT. That’s an awesome combo to behold, paired with 32GB DDR5-6000 during the AI-RAM-pocalypse. However, this build has become headlineworthy entirely due to its steampunk-inspired aesthetics. If Thomas Edison and George Stephenson had teamed up to build a gaming PC, it might have looked like this. Meanwhile, the weight of Redditor voting suggests that most think it looks like some kind of espresso coffee machine.

The crafty PC builder behind this new battlestation is Old-Mate-Fetus. Key to its visual appeal is the extensive use of copper cooling apparatus and wood. The images clearly show this open-build PC made with a custom liquid loop using copper pipes, elbow joints, and welds. These pipes meander around the build, feeding the Alphacool GPU block, the Heatkiller IV CPU block, and circulating around a large radiator up top. A copper design feature that really stands out, though, is the “reservoir made from an old Primus Blowtorch with sight gauge fitted to it.” Nice.

Old-Mate-Fetus sits the PC on a base/backing frame they also handmade using a dark hardwood with an antique finish, and brass screws. We can’t see it in the photos, so it's probably pretty safe to guess that the Corsair 850W SFX power supply is hidden in the wood base. The builder says that they also made custom cables from the PSU to the various components.

Custom PC component list:

If you are thinking the Old-Mate-Fetus design has some Billet Labs influence, and that it would be appreciated by them, “you are correct,” confirms the London-based copper pipe welder in the comments. The builder of this all-AMD machine warmly accepted the compliment. Redditors also joked about this new gaming PC possibly being the ultimate Steam Machine.

In an unexpected turn of events, Terafab has faced an odd roadblock as a small U.S.-based company called Tera-Print sent a cease-and-desist letter to SpaceX and Tesla back in May to stop using the Terafab name. The company with tera-scale ambitions has run into a tabletop-sized problem because the Tera-Fab name has already been used for about a decade by Tera-Print, according to PCMag.

As it turns out, Tera-Print sells tabletop-sized Tera-Fab-branded beam pen lithography (BPL) tools primarily aimed at bioengineering and prototyping of microfluidic devices and has used the brand for about a decade. The U.S. Department of Defense appears to be a client of Tera-print, which uses Tera-Fab.

While Tera-print claims that the Terafab name could be confused with its Tera-Fab product family, Tesla, SpaceX, and SpaceXAI counter that the operations are fundamentally different: Terafab is set to produce chips in extremely high volumes to serve AI, automotive, robotics, and eventually (at least some) space applications, whereas Tera-print's Tera-Fab is a compact lithography tool that can be used for bioengineering or prototyping of electronic or optical devices.

Formally, the trademark coverage puts both names into the same semiconductor technology bucket, albeit with different descriptions:

• Tesla's Terafab covers 'custom manufacture of semiconductor chips, memory chips, integrated circuits, and wafers' (IC 040) as well as 'distribution services, namely, delivery of semiconductor chips, chip carriers, namely, semiconductor chip housings, memory chips, integrated circuits, semiconductors, and microchips' (IC 039).
• Tera-print's Tera-Fab covers 'Polymer pen and beam pen lithography instruments in the nature of 3D micro-printers and 3D nano-scale printers' (IC 007); 'Polymer pen and beam pen lithography instruments in the nature of 2D micro-scale molecular and material printers and 2D nano-scale molecular and material printers' (IC 009), 'Light-directed photochemical synthesis tools; Industrial advanced materials synthesis tools; Advanced light projection systems; High precision force-feedback sample alignment modules; Environmental control sample chambers' (IC 009); as well as 'training services in the field of AI design and development, electronics, computer science, biology, and material science' (IC 042).

The two companies reportedly entered settlement talks, which included an offer from Tesla, but Tera-Print alleges that Tesla expressed interest in continuing negotiations instead of taking the dispute to court. Tera-Print says it will now defend its registered trademark and argues that the companies operate in related fields, which could lead to confusion.

Phoronix reported that Intel appears to have suspended its bounty program that once paid up to $100,000 per bug. Intel’s replacement for the Intigriti program offers no rewards, and no reason was given for the change. The Intigriti site states that it “is a responsible disclosure program without bounties,” confirming the report. A check of the site shows that the bounty board is still up but lists the program as suspended.

Intel’s site still lists details on the bug bounty program with awards that range “from $500 up to $100,000, based on quality of the report” and other factors. This program launched, invite-only, in 2017, and became open to all researchers in 2018, covering software, hardware, firmware, and open-source projects. Almost half of the CVEs Intel addressed in 2020, 105 out of 231, arrived through the bounty program, Intel said.

The old bounty board split vulnerabilities into four tiers, which were priced accordingly: Tier 1 from $2,000 to $100,000, Tier 2 $1,000 to $30,000, Tier 3 $500 to $10,000, and Tier 4 $250 to $5,000. Intel expanded the program’s scope to include web services between mid-2025 and October 2025, but it said in a January 6 update on Intigriti that it was evaluating “enhanced bounty and bonus criteria.” In about eight months, the bounties went from evaluation to suspension.

The outlet speculated that with the Linux kernel and other open-source projects being “bombarded” with security reports, it would not be surprising if AI bug-seeking played a role. Linux kernel CVEs have approached 2,000 per release, a fourfold increase from about 500, with maintainers “completely overwhelmed.” Linus Torvalds, the creator of the Linux kernel, has said that duplicate AI reports on the kernel security list are “almost entirely unmanageable.” Curl, for one, closed its bounty program due to AI slop floods.

As a point of reference, HackerOne’s Internet Bug Bounty (IBB) program paused submissions effective March 27. “AI-assisted research is expanding vulnerability discovery across the ecosystem, increasing both coverage and speed,” HackerOne said on the program’s page. HackerOne is still paying queued submissions, with rewards from $68 to $2,257 based on severity. This supports the idea that AI has affected software programs, but it may not be as significant for hardware and firmware.

Intel’s next steps are worth watching to see if this suspension ends up permanent in a fast-changing landscape. Researchers are still able to submit vulnerabilities through the new program; it just offers no bounties for them. Checking AMD’s Intigriti page today shows that the program there is also suspended, although Intigriti does have an auto-suspend mechanism. This follows an earlier payment dispute over scope with a bounty hunter in June.

Even if AI tools carry a stigma and may be a factor in these recent events, they have proven handy. AI company OpenAI paid Hacktron researchers a $6,500 bounty for a discovered exploit chain using rival Anthropic’s model. Torvalds, who previously dismissed AI as mostly marketing, has also called AI “clearly a useful” tool, and acceptance in the field may grow.

An Intel Celeron 1200 (Tualatin) was revived from the dead following an intricate bit of repair work by Bits und Bolts. The quarter-century-old chip looked like it had a fatal injury, with one of the pins missing and the underlying pad ripped off. As things stood, a system with this close relative of the Pentium III installed simply wouldn’t boot. However, thanks to careful digging “deep into the substrate” and some delicate preparation work, the enthusiast managed to solder on a donor pin and get this CPU running again – and then overclocked it by 33%.

As the Celeron 1200’s missing pin was a data pin (D47), this was a definite fix-or-be-damned situation. Sometimes CPUs can have a pin or two missing, and they will work anyway. I’ve seen CPUs shrug off such missing connections when several remaining pins duplicate a function – power or ground pins, for example.

Bits und Bolts started the repair process with a close-up of the serious-looking damage. Then we see the missing pin area after they have apparently “dug a hole” so that the work/issue can be seen more clearly. Zoomed-in images show that there were several layers of copper exposed from under the green surface. The new pin must be connected solely to the central circular area you can see, and not accidentally connect with any of the copper planes surrounding it. Thus, the TechTuber started by applying solder mask to this area. Remember, these pins are very small, and it would have been an intricate job to mask the surrounding area solidly yet cleanly.

While the solder mask surrounding the Intel Celeron 1200’s vacant pin cured, Bits und Bolts harvested a few pins from another Tualatin chip that was “definitely broken.” Returning to the CPU under repair, it was time to add flux, then try to ‘tin’ the central circular copper area to which the donor pin would be soldered.

Soldering the donor pin went smoothly, leaving it perfectly in position and upright. You can definitely see which pin has been added by Bits und Bolts, but after nervously adding the repaired Celeron 1200 to a socket, the TechTuber was relieved that everything mated cleanly.

Instead of firing up the computer with the repaired processor installed straight away, the tech tinkerer took a few readings with their multimeter. There were no obvious issues. At last, the moment of truth came, and the patched-up processor-packing PC system booted without issues. Bits und Bolts commented that this was the first time they’d repaired a processor pin issue that looked so grave. The end of the video sees the CPU tested in various benchmarks, including SiSoft Sandra. Moreover, it was even overclocked by 33%, stable at 1,600 MHz.
