Back in 2017, Hackaday featured an audio reactive LED strip project from [Scott Lawson], that has over the years become an extremely popular choice for the party animals among us. We’re fascinated to read his retrospective analysis of the project, in which he looks at how it works in detail and explains that why for all its success, he’s still not satisfied with it.
Sound-to-light systems have been a staple of electronics for many decades, and have progressed from simple volume-based flashers and sequencers to complex DSP-driven affairs like his project. It’s particularly interesting to be reminded that the problem faced by the designer of such a system involves interfacing with human perception rather than making a pretty light show, and in that context it becomes more important to understand how humans perceive sound and light rather than to simply dump a visualization to the LEDs. We receive an introduction to some of the techniques used in speech recognition, because our brains are optimized to recognize activity in the speech frequency range, and in how humans register light intensity.
For all this sophistication and the impressive results it improves though, he’s not ready to call it complete. Making it work well with all musical genres is a challenge, as is that elusive human foot-tapping factor. He talks about using a neural network trained using accelerometer data from people listening to music, which can only be described as an exciting prospect. We genuinely look forward to seeing future versions of this project. Meanwhile if you’re curious, you can head back to 2017 and see our original coverage.
Home appliances are a necessary part of life. Whether you rent or own your home, you’ve likely dealt with a defrosting refrigerator, a leaking dishwasher, or a washing machine that’s refusing to drain. When we purchase a new appliance, we hope to get years of service without costly repairs. Samsung, which sells all major types of home appliances, from basic, entry-level models to bespoke options with artificial intelligence, has been recognized by JD Power with high rankings for customer satisfaction. Yet many Samsung appliances tend to generate mixed reviews, with praise for design offset by concerns about reliability, performance, and customer service; in fact, the company recalled 2.8 million of its washing machines in the United States in 2016 due to issues that caused the top to detach while in use.
Of course, any appliance can break, and washing machines are typically heavily used and have complex components, facts that often tend to contribute to these home appliances having a slightly shorter lifespan than others. Overloading your machine or failing to clean it and perform regular maintenance may lead to your washer needing expensive repairs, or it could shorten that lifespan even further. If you already own a Samsung washing machine or you’re in the market for a new washer, here are four common problems endemic to the brand to watch for.

The controls stop working

We’ll start the conversation with a common problem and a simple fix. If your washer won’t start, the buttons aren’t working, or the control knobs won’t allow you to select a cycle, you may have accidentally turned on the child lock. That’s right, you can lock your child out of YouTube, into your car and, it turns out, also out of your washing machine.
The child safety locks disable the machine’s controls and often lock the door. They help keep your child from playing with the buttons, accidentally starting the machine, or even from crawling inside, where they could be hurt or worse. If you don’t have children or your children are old enough to leave your washer alone, you probably don’t bother with the lock. On most Samsung machines, it’s not easy to accidentally turn on, but it is possible. The lock is activated with a two-button combination that’s labeled on the control panel. It’s typically labeled with the words “Child Lock” or a lock icon. Check your user manual if you’re unsure how the lock on your machine works. When the lock is activated, you should hear a chime and an icon should light or flash. To deactivate the lock, press and hold both buttons once to see the icon flash, then again to make the icon turn off.
If you try these steps and your washer still won’t start, it’s likely a different problem. Samsung recommends you unplug the machine, let it sit for at least a minute to reset, then plug it back in again.

The washer isn’t filling properly

You load up the washing machine, add detergent and press start, only to be met with silence. You lift the lid and take a look, and your clothes are still dry and dirty. The machine isn’t filling, or perhaps it’s only filing part way and not finishing the job. Even high-efficiency washing machines need water, so what is going on?
A filling error may be indicated on a Samsung machine with an error code or by a blinking light on the indicator for the fill level (Extra Large, or Extra High, for example). The manufacturer has several recommendations if you encounter this frustrating problem. First, be sure your supply hoses, both hot and cold, are properly connected to the washer and aren’t kinked or pinched anywhere. Also verify that the water valves are open. You should also check the drain hose connections. Samsung recommends that you don’t remove the screw on the back of the washer that holds that drain hose against the machine. If the screw is missing, use any screw that fits to replace the holder.

If all the hoses appear functional, try unplugging the washer or flipping the circuit breaker for at least a minute to reset the machine. If it still isn’t filling properly, call a professional.

The washing machine isn’t draining

If your problem is too much water rather than not enough, your Samsung washer may not be draining properly. If you’re lucky, you may simply receive a “no drain” or “overflow water” error code. If you’re unlucky, your washer will leak, possibly overflow, and likely create a big, expensive mess. Water damage is no joke, so this is a problem you’ll want to address before that happens.
If you didn’t have your washer professionally installed, be sure the machine is level before you use it, otherwise it may not drain properly. If you know the machine is level, inspect the drain hose. Samsung advises that the hose should not be inserted less than 6 inches and more than 8 inches into the standpipe. Be sure it is secured to the machine and is not bent or damaged, and has not formed an airtight connection. It needs to be placed at least 18 to 24 inches high, depending on the type of washer, and no higher than 96 inches. Samsung also notes that users should not install a drain hose extension kit.
Finally, if you have a front load washing machine, you may need to clean the pump filter. If the filter is clogged, the draining system may not work effectively. Once you run through all these steps, try to run the washer again; if it’s still not draining, it’s time to call in a professional.

The washer’s door is broken or its buttons are jammed

Problems with washing machines don’t always involve water. If your Samsung machine isn’t working and the “Hot” and “Large” (or similarly labeled) buttons are flashing, or you receive an error code that indicates a door error, your washer is telling you that it’s detecting that its door is either damaged or not closed properly. Check your manual to confirm the error code, then take a look at the door latch. It could be as simple as a sock or a drawstring stuck in the door. The door lock may also be malfunctioning, or the problem could be with the door itself. If you don’t see anything wrong with the door and cannot clear the error code, you should contact Samsung’s support center.
If you receive a jammed button error code, your washer is telling you that one or more of the buttons on the control panel is stuck or being continuously pressed. Samsung recommends that you turn off your washer, then check each button individually. If a button is damaged or the code doesn’t clear after you power on the washing machine, again, request support from Samsung for a repair.
Of course, there’s a long list of other possible error codes and potential problems or malfunctions. If your washer displays an error code or simply stops working, check your manual or Samsung’s website for support. If you’re unable to diagnose or solve the problem, a dreaded repair or replacement may be in order.
The global AI boom has exposed how unprepared we really are for such rapid data center expansion, and we’ve already reached the point where construction is struggling to keep pace with the continued rate of innovation.
Nowhere is this more evident than across the US, where hyperscalers and cloud providers are racing to build out new data center campuses capable of supporting the next wave of agentic AI workloads. This is, of course, as companies continue to push the boundaries with next-gen frontier models, with both electrical supply and cooling infrastructure in hot demand.
However the hype has left utilities under pressure to make grid connections faster than ever, and contractors are facing strict and often unrealistic timelines to get facilities built and connected.

Rapid scaling is driving misalignment between tech, construction and utilities
However, Steel Tube Institute’s Dale Crawford doesn’t believe that the ongoing skills shortage is necessarily a lack of capable people. Instead, the problem lies in how quickly the sector is scaling before a shared understanding has fully developed across the workforce. In other words, the sector is expanding before companies have had time to upskill their employees.
The challenge extends far beyond AI data centers alone, though, with similar high-density electrical systems increasingly appearing in hospital, industrial facilities and food processing plants, suggesting the industry may be entering a much bigger shift in how infrastructure demands are to be met.
It’s the speed of AI growth in particular that’s really highlighted this problem, though, leaving little time to develop standardized best practices, leaving suppliers to learn in real time instead,

To better understand the AI boom’s impacts on electrical infrastructure and construction, I spoke with Steel Tube Institute Executive Director Dale Crawford about the growing expertise gap, the pressure that contractors and inspectors are facing, and why standardization and investment in people may become just as important to AI infrastructure as GPUs.

The utility business is notoriously slow to change and often plagued by underinvestment. The AI industry is exactly the opposite, flush with cash and wanting tomorrow’s progress yesterday. Surely getting these two to work together can only end in tears?
The bigger issue isn’t incompatibility, it’s alignment at a very technical level. Projects are moving from design to installation before there’s a shared understanding of how these high-density systems are being implemented in the field.
When that shared understanding isn’t fully developed, the margin for misalignment across design, installation and inspection narrows, and that’s where challenges begin to surface.
From a steel conduit standpoint, that shows up on how raceway systems are specified versus how they’re installed and inspected under compressed timelines. Steel conduit is often selected for its durability and predictable performance, but if the team isn’t aligned on installation practices and code interpretation, even proven systems can become points of friction.

When that shared fluency isn’t there, the margin for misalignment narrows significantly. That’s where issues emerge. Because the system as a whole hasn’t developed a consistent, shared understanding at the same rate as the infrastructure is being deployed
Can you dig deeper into the challenges contractors, inspectors and project teams are encountering on these data center projects?
The systems themselves have evolved quickly. High-density loads, redundant architectures and advanced distribution configurations have become standard in a relatively short period of time.
The challenge is not any one part of the project team. It is the speed, scale and density of these projects. Contractors are installing large raceway systems in tighter, more congested environments, designers are adapting to rapidly evolving load and redundancy requirements, and AHJs are reviewing highly complex installations on aggressive schedules.
When design intent, installation practices and inspection expectations are not aligned early, issues can surface at the handoff points.

The best way to reduce delays and rework is to build that alignment into the project from the beginning through clear specifications, proven materials, code-aligned installation practices and early communication among the project team and the AHJ.
You mention a raft of solutions in an email you shared with me. On paper, they look great but they would take time to implement and if there’s one thing hyperscalers and the AI industry is short of, it’s definitely time.
There is a perception that standardization and education slow projects down, but in practice, the projects that stay on schedule are often the ones built around systems everyone already understands.
Well-established, code-aligned materials like steel conduit provide familiar performance characteristics and a common language across designers, contractors, inspectors and owners.
That consistency helps reduce interpretation gaps, supports a smoother review process and lowers the risk of late-stage changes or rework. In fast-moving data center construction, standardization is not a delay. It is one of the ways projects keep moving
Part of the problem is that the current explosion in demand was not foreseen by anyone. It just happened, making it impossible to gather data sets and expertise that is often the driving force for long-term reliability of mission critical facilities. What are your views on that?
The pace and scale of demand, particularly tied to AI, accelerated beyond expectations, and the traditional pace of workforce development hasn’t kept up. That puts the industry in a position where systems are evolving faster than experience can accumulate, making continuous, structured education essential for deeper technical understanding.
From a conduit perspective, the applications themselves aren’t new, but the scale, density and integration of these systems are. At the same time, established standards and proven approaches help bridge that gap by providing a consistent framework that supports alignment even as systems evolve.

Now, let’s be blunt. The industry needs experts and people with experience and we need them now. That will take years given the current environment. Should investment in training happen right now or could we end up with a bunch of experts twiddling thumbs after the AI bubble exploded?
This isn’t limited to data centers. The same complexity in electrical systems and the same reliance on robust, well-understood raceway solutions, such as steel conduit, are showing up in hospitals, food processing facilities and other mission-critical facilities.
This reflects a broader structural shift in electrical infrastructure, not a short-term cycle, so investing in training is about ensuring systems can be delivered safely and consistently.
The greater risk is the cost of operating without sufficient expertise in environments where performance, uptime and compliance leave very little margin for error.
Go from 4K resolution for Crimson Desert to 680Hz for Counter-Strike 2.

Gaming monitors that let you switch between two modes aren’t new, but MSI is pushing that even further with its OLED monitor can shift across three modes. For Computex 2026, MSI is claiming a world’s first with a 31.5-inch gaming monitor that can bounce between 4K resolution with a 360Hz refresh rate, 2K resolution with 520Hz and FHD resolution with 680Hz.
Officially named the MPG OLED 322URDX36, the monitor lets gamers go from maximum resolution for AAA titles that are graphically demanding to an ultra-fast refresh rate for more competitive games where split-second decisions matter. Along with MSI’s Triple Mode feature, the upcoming monitor also has its Penta Tandem technology that the company advertises as a five-layer stack of panels designed to reduce color fringing and make text more legible. MSI also equipped the Triple Mode monitor with a DarkArmor Film that’s supposed to boost black levels by 40 percent and increase scratch resistance.
Besides all of MSI’s included proprietary technologies, the upcoming monitor can hit a peak brightness of 1,500 nits and will have a DisplayPort 2.1a and a USB-C port. MSI didn’t reveal any pricing or release details, but said the MPG OLED 322URDX36 will be on display at its booth during Computex 2026, which kicks off on June 2.
Rust is the kind of survival game where choosing the right server matters almost as much as choosing the right weapon. This also reflects on the platform of your choice. If you’re you’re friends are spread across PC, PlayStation, and Xbox, you’ll want to know exactly who can play together before anyone starts building a base.
The answer to the question is simple in one way and annoying in another. Rust supports crossplay between PlayStation and Xbox players, but PC players cannot play with console players. So yes, there is cross-platform support, but only inside the console version of the game.
And because Rust on PC and Rust Console Edition are not treated as one shared version across every platform. They are separate enough in updates, content, performance, and server structure that you can’t just jump from PC into a console lobby.
Rust – Naval UpdateFacepunch
Can you play Rust cross-platform?
Rust is cross-platform on consoles, but not between consoles and PC. Rust Console Edition players on PlayStation or Xbox can play with other console players. This includes both the PlayStation and Xbox ecosystems, though the console version has been changing as Double Eleven moves toward native PS5 and Xbox Series X/Series S support.
On the other hand, PC players are kept separate. Rust players on PC are playing exclusively in the PC pool, and not with PlayStation or Xbox users. So a player on Steam cannot join his friend playing Rust Console Edition on PS5 or Xbox Series X/S.

Does Rust have cross-progression?
No, don’t expect your progress to follow you across platform families. Double Eleven has said cross-platform progress transfer is not an option in Rust Console Edition. So you should treat your paltform choice seriously. This is even more important to note before you start purchasing skins and are focusing on progressing in one ecosystem.
What about modded and community servers?
This is another reason PC remains the best version if you have the choice. PC Rust has a stronger server ecosystem, including modded servers and more custom ways to play. This is exactly what made Rust so popular, and why fans gravitated towards PC. Console players are not completely stuck with official servers, with support for community servers. These let you tinker with the rules, settings, moderation, and other aspects. But it’s still behind the modded servers on PC.

A single npm user on Thursday published 14 malicious packages within a four-hour window, all mimicking popular OpenSearch, Elasticsearch, DevOps, and environment-configuration libraries, according to Microsoft.
Using a newly created maintainer alias, vpmdhaj (a39155771@gmail[.]com), the threat actor published 14 packages impersonating legitimate libraries from the @opensearch and @elastic ecosystems and targeting Amazon Web Services, HashiCorp Vault, GitHub Actions, and the npm registry itself. This suggests that the attacker “likely chose a developer audience to have AWS and Elastic cloud credentials in their environments,” Microsoft warned in a Thursday blog.
All of the malicious packages include the same install-time stager and the same Bun-compiled, second-stage payload: a 195 KB credential harvester purpose-built for cloud and CI/CD environments.
Plus, as we’ve seen with all of the other open source supply chain attacks of late, after stealing tokens and other secrets, the attacker can move laterally across cloud environments, steal additional sensitive data, and push even more poisoned updates to packages owned by hijacked maintainer identities, thus expanding the attack beyond the initial 14.
All of the malicious libraries have since been removed, and Microsoft published a list of all 14 in its blog. Give that a read to help identify systems that installed or built affected package versions on or after May 28. Be sure to also rotate an AWS IAM/STS, HashiCorp Vault, npm publish, and GitHub Actions tokens that may have been exposed.

To trick users into installing these developer tools and search engines, the attacker used typosquatting – naming a package one or two letters off from the legitimate one – or lookalike naming (such as opensearch-setup-tool, opensearch-config-utility, and elastic-opensearch-helper) to impersonate well-known libraries.
In addition to this social engineering technique, used to drive installs through users’ typing mistakes or trust, the attacker also used two other techniques to make the supply chain attack more believable.
This includes spoofing upstream metadata. “Every unscoped package sets its package.json homepage, repository, and bugs fields to the legitimate github.com/opensearch-project/opensearch-js project,” Microsoft’s threat hunters explained.
And finally, they inflated version numbers, so the phony “releases” jump straight to 1.0.7265, 1.0.9108, or 2.1.9201 to indicate a mature release history.

After tricking users into installing the npm packages – all 14 are listed in the blog, so give that a read – the credential-stealing payloads automatically execute through preinstall hooks as soon as the victim runs npm install.
For this, the attacker used one of two stagers. The Gen-1 stager uses install, preinstall, and postinstall hooks that all invoke preinstall.js, and then collects a ton of host information including hostname, platform, arch, Node version, USER/USERNAME, cwd, INIT_CWD, npm_package_name, npm_package_version. It then base64-encodes the JSON, and POSTs it to the actor’s command-and-control server, which then serves a second-stage payload, written to payload.bin in the package install directory.
“The package’s index.js re-launches the same payload.bin on every subsequent require() of the module – a quiet persistence mechanism that survives across CI build stages and developer rebuild loops,” according to Microsoft.
The later Gen-2 stager replaces the install-time C2 roundtrip with a stealthier loader that checks whether bun is already present on the host. If not, it downloads the legitimate Bun runtime v1.3.13, and then executes the second-stage payload, which sets to work stealing credentials across AWS, HashiCorp Vault, npm, GitHub Actions, and other CI/CD environments.®
Meta is developing an AI-powered pendant that it plans to start testing in the next year, according to a memo viewed by The Information.
This device would presumably build on the work of Limitless, an AI device startup that Meta acquired at the end of 2025. The startup made an AI pendant that users could attach to their shirt or wear as a necklace to record their conversations. At the time, Meta said the acquisition would allow it to “accelerate our work to build AI-enabled wearables.”
The memo also reportedly states that the company is planning to expand its lineup of AI glasses and launch a business subscription called Wearables for Work. With all these planned devices, Meta is apparently hoping to reverse the fortunes of its hardware-focused Reality Labs division, which lost $4 billion in the first quarter of this year.
A new pair of Beats headphones are on the way, as a new unnamed model surfaces in a series of Instagram posts by football star Lamine Yamal.
On May 23, some mystery headphones appeared in an FCC filing, indicating a new pair was coming out of Cupertino. One week later, an Instagram post has shown that it’s from Beats.
The shots on the official account for Lamine Yamal showed the sporting celebrity wearing and carrying around some bright pink headphones. In the four photographs and one video, the headphones are either around his neck or hanging off a bag to his side.
Three of the shots give a clear look at the headphones, complete with the side “b” logo synonymous with Beats headphones.

Though the post doesn’t mention the headphones directly, nor offer any real information about them, we can tell from the images that they have an over-ear earcup design. This closely matches the simple drawing shown in the FCC filing.
While there are no real rumors about Beats headphones, the most probable match would be an update to the Beats Studio Pro, originally released in July 2023. While there are no other details for the headphones as of yet, the appearance with a celebrity indicates that a launch could happen within weeks.
Celebrity tease
Lamine Yamal is a prominent football player who plays for La Liga club Barcelona, as well as the Spain national team. In the clips, he is shown traveling to a training camp ahead of the World Cup.

At the time of publication, Yamal has 43 million followers on Instagram. After an hour, his Beats-containing post achieved more than 1 million likes and 5.1 thousand comments.
The use of a celebrity on Instagram as the initial tease for a product launch is a typical promotion strategy for the Apple subsidiary. Regularly, Beats uses sports stars to promote earbuds, headphones, and speakers long before their launch.
BORK!BORK!BORK! The National Space Centre in England took things a little too far with its simulation of a rocket launch, unless it was seeking to recreate NASA’s leaking Space Launch System (SLS) via a plastic bottle and some water.
The Leicester-based museum features exhibits aplenty, including some rockets to gawp at, an intriguing parafoil-equipped Gemini capsule, a planetarium, and lots of interactive stations to educate and inform visitors about the space age.

Some of those interactive exhibits can, however, be a little too realistic for comfort, such as a bottle rocket intended to illustrate the Space Race between the United States and the Soviet Union.
It’s a simple enough concept. Select a rocket type, learn some stuff about it, watch as a water bottle is pressurized, listen to the countdown, and then liftoff! It’s an activity that kids – and adults – might have attempted in a garden or park.
Things didn’t go as planned at the National Space Centre, and was reminiscent of the repeated leaks NASA’s SLS suffered during launch preparations. Where the exhibit’s Soviet Union’s bottle blasted off as expected, the American one did not. It spewed water from the base in an unintended recreation of NASA’s initial attempts to fuel the SLS, before giving a pathetic twitch when the countdown reached zero.
The National Space Centre exhibitRichard Speed
Still, it could have been worse. Had the museum decided to recreate the failure of the Soviet Union’s N1 Moon rocket, or Blue Origin’s explosive test of its New Glenn this week, onlookers might have needed a change of clothes after a sudden, and very watery, boom.

The interactive display might not be quite what the museum intended, but it indicates that even in the high-tech world of the space age, the curse of bork is never far away.
Unless, of course, the plan was always to remind users of SLS leakage, if not the explosive excesses of today’s commercial providers.
The National Space Centre told us:
“We currently have one water rocket out, the USA rocket. There are these bands that are needed to keep the bottle in place within its frame, the bands for that rocket snapped a few times recently so we have run out of spares and are waiting on parts be delivered for it to be back in action, but the soviet rocket is completely fine and has been all week.” ®
This is, without a doubt, more work than setting up Wispr Flow. When you’re done, though, you have a working application with no monthly subscription. I recommend trying it out.
A Few Other Free Alternatives
Like I said before: AI transcription and LLMs are both widely available technologies. It should be no surprise, then, that there are many Wispr Flow alternatives out there right now.
For Mac users, the completely free and open source MacParakeet is a great option. It’s open source and completely free to download and use without an account. There’s also no upselling in the application. Transcribing is handled using local models, either Parakeet or Whisper, and a variety of LLMs—both local and online—are supported for the formatting step. That’s the closest completely free app to Wispr Flow I’ve found.
VoiceInk, another Mac-only option, is open source and free to use if you download the code from GitHub and compile it yourself. The app otherwise costs $25, one time, after which you can use all features without any ongoing payments. Note that the formatting step for this requires an API key from a service such as Gemini, Anthropic, OpenAI, or Claude.

Windows and Linux users should look into FOSS Voquill, which is completely free, open source software (hence the FOSS), and works offline. It doesn’t offer a formatting step, which is disappointing, but I’m including it because it’s the best free Windows and Linux option I’ve found without any annoying upselling.
Windows users and Mac users who don’t like the above options for any reason have one more choice: OpenWhispr. This open source tool doesn’t require an account (but you’ll have to find a tiny “Continue without an account” button). The application offers a subscription, but you can opt to set up local models and external API keys instead to avoid paying.
Do You Really Need to Type With Your Voice?
Wispr Flow has its upsides. It’s easy to configure, for one thing, and has a consistent user interface. I can understand why someone might opt to pay for a subscription. But if money is tight right now, there are free options available.
I had fun exploring this growing field, but I’m going to stick to my keyboard. Wispr Flow, and apps like it, promise to let you write at the speed of thought, but I type faster than I think. If I can be philosophical for a second, writing is how I think. Typing a sentence, looking at it, and refining it isn’t an annoying part of the writing process—it is the writing process. And I often don’t know what my opinion on something is until I take the time to refine my thoughts. I can’t help but feel a lot of that would be lost if, instead of typing, I just talked to my computer.

But every brain is different, and these tools may work well for you. Which is why I’m glad there are so many options out there.
