The WalMart Atomic Clock | Hackaday

Published

on

In the realm of first-world problems, your cheap wall clock doesn’t keep time, so you have to keep setting it. The answer? Of course, you connect it to NTP and synchronize the clock with an atomic time source. If you are familiar with how these generic quartz clock movements work, you can probably guess the first step is to gut the movement, leaving only the drive motor.

The motor is somewhat like a stepper motor. The ESP8266 processor can easily control the clock hands by sending pulses to the motor. The rest is simple network access and control. If the network time is ahead, the CPU gooses the clock a little. If it is behind, the CPU stalls the clock until it catches up.

If you’ve ever done a project like this, you know there is one major problem. At some point, the processor needs to know where the hands are now. On initial setup, you can force the issue. However, if the power goes out, it won’t work well. If the power goes out at, say, 8 AM and turns back on at 9 AM, the CPU will be happy to correct the time to agree with the NTP time. The problem is that the processor has no idea that the hands started at 8 AM, so the time will be off.

To combat this problem, the design uses an EERAM chip to store the current time. In the event of a power failure, the CPU knows where its hands are and can adjust accordingly.

While you usually use these movements to keep time, once you can control them, you can do any crazy thing you like. Or, even anything as artistic as you can dream up.

India has 100M weekly active ChatGPT users, Sam Altman says

Published

on

India has 100 million weekly active ChatGPT users, making the country one of OpenAI’s largest markets globally, CEO Sam Altman said ahead of a government-hosted AI summit.

On Sunday, Altman outlined ChatGPT’s growing adoption in India in an article published in the Indian English daily Times of India, as OpenAI prepares to formally participate in the five-day India AI Impact Summit in New Delhi, beginning Monday. Altman is attending the event alongside senior executives from several of the world’s leading AI companies.

The growth comes as OpenAI, like other leading AI firms, looks to India’s young population and its more than a billion internet users to fuel global expansion. The ChatGPT maker opened a New Delhi office in August 2025 after months of groundwork in the country, and has adjusted its approach for India’s price-sensitive market, including rolling out a sub-$5 ChatGPT Go tier that was later made free for a year for Indian users.

In the article, Altman said India is ChatGPT’s second-largest user base after the United States, highlighting the South Asian nation’s growing weight in OpenAI’s global strategy. The disclosure comes as ChatGPT’s overall usage has surged worldwide, with the platform reaching 800 million weekly active users as of October 2025 and reported to be approaching 900 million.

Altman also highlighted the role of students in driving adoption, saying India has the largest number of student users of ChatGPT globally.

Indian students have become a key growth segment for leading AI companies more broadly, as rivals race to embed their tools in classrooms and learning workflows. Google has similarly targeted the market, offering Indian students a free one-year subscription to its AI Pro plan in September 2025. Separately, India accounts for the highest global usage of Gemini for learning, Chris Phillips, Google’s vice president and general manager for education, said last month.

“With its focus on access, practical Al literacy, and the infrastructure that supports widespread adoption, India is well positioned to broaden who benefits from the technology and to help shape how democratic AI is adopted at scale,” Altman wrote.

ChatGPT’s rapid growth also highlights a broader challenge for AI companies in India: translating widespread adoption into sustained economic impact. Indian government initiatives such as the IndiaAI Mission — a national program aimed at expanding computing capacity, supporting startups and accelerating AI adoption in public services — seek to address those gaps. However, the country’s price-sensitive market and infrastructure constraints have made monetization and large-scale deployment more complex than in developed economies.

“Given India’s size, it also risks forfeiting a vital opportunity to advance democratic AI in emerging markets around the world,” Altman wrote, warning that uneven access and adoption could concentrate AI’s economic gains in too few hands.

Altman also signaled that OpenAI plans to deepen its engagement with the Indian government, writing that the company would soon announce new partnerships aimed at expanding access to AI across the country. He did not provide details, but said the focus would be on widening reach and enabling more people to put AI tools to practical use.

The India AI Impact Summit is expected to draw a wide cross-section of global technology and political leaders, including Anthropic CEO Dario Amodei, Sundar Pichai of Google, and senior Indian business figures such as Mukesh Ambani and Nandan Nilekani. Political leaders including Emmanuel Macron, Sheikh Khaled bin Mohamed bin Zayed Al Nahyan, and Luiz Inácio Lula da Silva are also expected to attend, spotlighting India’s ambition to position itself as a central player in global AI debates.

For global AI firms, including OpenAI, the summit underscores how India’s vast user base is translating into growing influence over how the technology evolves.

Oldest Active Linux Distro Slackware Finally Releases Version 15.0

Published

on

Created in 1993, Slackware is considered the oldest Linux distro that’s still actively maintained. And more than three decades later… there’s a new release! (And there’s also a Slackware Live Edition that can run from a DVD or USB stick…)
.

Slackware’s latest version was released way back in 2016, notes the blog It’s FOSS:


The major highlight of Slackware 15 is the addition of the latest Linux Kernel 5.15 LTS. This is a big jump from Linux Kernel 5.10 LTS that we noticed in the beta release. Interestingly, the Slackware team tested hundreds of Linux Kernel versions before settling on Linux Kernel 5.15.19. The release note mentions… “We finally ended up on kernel version 5.15.19 after Greg Kroah-Hartman confirmed that it would get long-term support until at least October 2023 (and quite probably for longer than that).”

In case you are curious, Linux Kernel 5.15 brings in updates like enhanced NTFS driver support and improvements for Intel/AMD processors and Apple’s M1 chip. It also adds initial support for Intel 12th gen processors. Overall, with Linux Kernel 5.15 LTS, you should get a good hardware compatibility result for the oldest active Linux distro.
Slackware’s announcement says “The challenge this time around was to adopt as much of the good stuff out there as we could without changing the character of the operating system. Keep it familiar, but make it modern.”

And boy did we have our work cut out for us. We adopted privileged access management (PAM) finally, as projects we needed dropped support for pure shadow passwords. We switched from ConsoleKit2 to elogind, making it much easier to support software that targets that Other Init System and bringing us up-to-date with the XDG standards. We added support for PipeWire as an alternate to PulseAudio, and for Wayland sessions in addition to X11. Dropped Qt4 and moved entirely to Qt5. Brought in Rust and Python 3. Added many, many new libraries to the system to help support all the various additions.


We’ve upgraded to two of the finest desktop environments available today: Xfce 4.16, a fast and lightweight but visually appealing and easy to use desktop environment, and the KDE Plasma 5 graphical workspaces environment, version 5.23.5 (the Plasma 25th Anniversary Edition). This also supports running under Wayland or X11. We still love Sendmail, but have moved it into the /extra directory and made Postfix the default mail handler. The old imapd and ipop3d have been retired and replaced by the much more featureful Dovecot IMAP and POP3 server.

“As usual, the kernel is provided in two flavors, generic and huge,” according to the release notes. “The huge kernel contains enough built-in drivers that in most cases an initrd is not needed to boot the system.”

If you’d like to support Slackware, there’s an official Patreon account.
And the release announcement ends with this personal note:


Sadly, we lost a couple of good friends during this development cycle and this release is dedicated to them. Erik “alphageek” Jan Tromp passed away in 2020 after a long illness… My old friend Brett Person also passed away in 2020. Without Brett, it’s possible that there wouldn’t be any Slackware as we know it — he’s the one who encouraged me to upload it to FTP back in 1993 and served as Slackware’s original beta-tester. He was long considered a co-founder of this project. I knew Brett since the days of the Beggar’s Banquet BBS in Fargo back in the 1980’s… Gonna miss you too, pal.

3 Home Depot Finds That Outshine Lowe’s In Price And Quality

Published

on





We may receive a commission on purchases made from links.

When it’s time to shop for items to complete our DIY projects, we often compare prices and availability between Lowe’s and Home Depot to see which store offers the best deal. Since we can generally find at least one competitively-priced version of what we need at either store, sometimes the difference comes down to which store is more convenient. Both Lowe’s and Home Depot offer online shopping and expansive stores with knowledgeable retail associates to help you select DIY products, Pro Desk services to streamline your business, and rental counters that provide access to the tools and equipment you need on occasion but don’t want to purchase.

The big-box home improvement stores each sell a number of popular name brands and some that are unique to each. Home Depot has its own private label brands, Husky is one example, while Lowe’s carries its Kobalt brand tools. Some name brands only appear at one or the other, like Lowe’s sells Craftsman tools but not Milwaukee, while that situation is reversed at Home Depot. Other than the particular brands found at Lowe’s and Home Depot, another difference is the number of physical locations they offer. Home Depot’s website boasts “more than 2,300 stores across North America,” while Lowe’s claims it “operates over 1,700 home improvement stores.”

Home Depot’s tool and equipment rental service outshines Lowe’s

Lowe’s and Home Depot are just two of the stores that offer tool rental services. I have personal experience with Home Depot’s rental counter because it was the closest place available to rent a mini excavator on a sub-zero New Year’s Eve morning to repair a waterline break at my house. However, I haven’t used Lowe’s rental services.

On that day, there was a Lowe’s that might have been closer, but it didn’t have a rental department, which is one of the things that makes Home Depot’s rental service better: it’s available in more locations. For example, while there are several Lowe’s stores within 50 miles of northeast Oklahoma, the nearest Lowe’s with a rental department is in Farmington, Missouri, over 300 miles away, according to the Lowe’s store finder.

Both stores offer a wide variety of tools and equipment for construction, lawn care, portable power, painting, and floor care. While we didn’t compare prices and specs of every rental product, many of the items were of similar quality with nearly identical prices and terms. One specific equipment rental category where Home Depot outshines Lowe’s is skid steers.

Lowe’s lists a single model, a John Deere Wheeled Skid Steer 318G, on its website. It comes on a trailer and has a combined weight of 8,842 pounds, requiring a ¾-ton or larger pickup equipped with a 2-5/16-inch trailer hitch ball to tow it. Lowe’s rental fees range from $284 for four hours to $379 for 24 hours and $1,137 for a full week. Home Depot rents a similar machine for a few dollars less, but really outshines Lowe’s with its selection of seven skid steer classes offering both wheeled and tracked versions, plus two more mini skid steer options.

Home Depot’s Husky 14-inch pipe wrench outshines Kobalt

A pipe wrench is a must-have tool to have on hand before starting a plumbing project. Pipe wrenches can also serve as a heavy-duty wrench to loosen stubborn nuts and bolts, as long as you don’t care what they look like when you’re finished.

Advertisement

Home Depot and Lowe’s both sell pipe wrenches, of course. You will find Husky and Kobalt pipe wrenches featuring aluminum and cast iron construction in a variety of lengths at their respective stores. A common pipe wrench selection with a variety of DIY applications is the 14-inch cast iron version. That specific pipe wrench from the Lowe’s Kobalt brand lists for $26.36, whereas the Husky 14-inch Cast Iron Pipe Wrench from Home Depot is a couple of bucks less at $23.97.

Both pipe wrenches have a 2-inch maximum jaw opening designed to work best on pipes up to 1.5 inches in diameter. However, the Kobalt pipe wrench lists its minimum pipe diameter at ½-inch compared to Husky’s ⅛-inch. They also each have a lifetime warranty.

While the Husky 14-inch cast iron pipe wrench from Home Depot beats the Lowe’s Kobalt pipe wrench on price, it’s also better quality, according to a video review posted to the Catus Maximus YouTube channel. Maximus reports that both pipe wrenches are less expensive and lighter than premium brands, while the Husky is a little lighter than the Kobalt.

The Husky 14-inch pipe wrench really outshines the Kobalt with its superior movable jaw. While pipe wrench movable jaws always have some play, the Kobalt design has an excessive amount that makes it less efficient to operate. Maximus demonstrates that Kobalt uses a movable jaw that’s thinner than Husky’s, resulting in a larger gap between the jaw and the frame and allowing for more side-to-side movement.

Entry-level DIY 2-tool combo kits

Whether it’s time to replace your old power tools or you’re just starting your collection, choosing a brand you can grow with is important. One reason is that whichever brand you go with will use batteries with proprietary designs. That means you’ll want to choose from a selection of power tools designed for that battery system going forward.

Home Depot carries Ryobi power tools, a popular entry-level DIYer budget-friendly option, and part of my personal tool kit. If you’re just starting to dip your toes into the proverbial power tool pool, Ryobi is a great brand with several tool options, but you won’t find them at Lowe’s.

Ryobi also has one of the least expensive options to get started. Home Depot lists a Ryobi 2-Tool Combo Kit for $99.00. The kit includes a ⅛-inch capacity drill/driver, an impact driver with a ¼-inch quick-connect collet, a 1.5 amp-hour lithium-ion 18-volt battery, and a battery charger. The 2-speed drill/driver provides up to 515 inch-pounds of torque and speeds up to 450 rpm in low range or 1,750 rpm in high. The impact driver delivers 3,450 impacts per minute (IPM) and up to 1,800 in-lbs of torque. Both tools have integrated LED work lights.

The least expensive comparable power tool kit from Lowe’s is the Black+Decker Drill Impact 2 Kit at $119.00. Lowe’s doesn’t provide detailed specs for the drill provided with the kit, but the impact driver generates up to 1,375 in-lbs of torque with 3,900 IPM. Generally, reviews comparing Ryobi power tools to Black+Decker find the Ryobi brand superior.

How we chose these Home Depot finds

The process of choosing Home Depot finds that outshine those from Lowe’s in quality and price involved the author’s personal experience and a lot of combing through offerings from each home improvement store to compare prices and online reviews to ensure superior levels of quality.

As always, prices and availability can vary in different parts of the country. Sale prices can also create instances where Lowe’s products beat those from Home Depot. In general, manufacturers of name-brand products, tools, and appliances control pricing, so the cost of those items is largely the same at both stores.

There’s the Mac Mini, and Then This Mini Mac You Never Knew You Needed

Published

on

Custom Mini Mac Build Wondermac
Apple’s Mac Mini has been sitting quietly on desks all across the world, pushing through daily business and creative chores with the simplicity of a small powerhouse. In spirit, if not in design, it is right next to an equally little, yet quite different, machine known popularly as the Mini Mac, or Wondermac in some circles. This little device began life as a Maclock, a desk clock that looks exactly like the original 1984 Macintosh, complete with the instantly identifiable beige shell, a teeny-tiny screen bezel, and even a false floppy disk port, but what occurs next adds a lot of complexity to what was once a simple gimmick.



YouTuber This Does Not Compute disassembled the Maclock and then rebuilt it from the ground up, using a Raspberry Pi Zero 2 W, a chip small enough to fit discreetly inside the clock’s shell but powerful enough to tackle the work at hand. He combined it with a 2.8-inch Waveshare LCD panel, which is small enough to fit comfortably behind the curved plastic lens that attempts to simulate an old-school CRT monitor. The resolution is a respectable 640×480, which complements the old atmosphere perfectly. For power, he used a customized USB-C connection on the back, which was tuned to produce a clean 5 volts after some fiddling with the original charging circuit to bypass it. Then there’s a little heatsink that quietly keeps the Pi from overheating without creating any fan noise.

OIJ Maclock Retro Pixel Alarm Clock, 1984 Computer-Inspired USB Desk Clock with Pixel Display, Multiple…
  • 【Retro 1984 PC Design】 This miniature ivory-colored ABS/PMMA alarm clock revives the charm of the early computer era. A perfect nostalgic piece…
  • 【Multi-Mode Pixel Display】 The high-contrast LCD simultaneously displays time, calendar, date, and room temperature. A hidden pixel smiley…
  • 【Adjustable Brightness for Comfort】 Gentle, warm backlighting in the morning and dim lighting at night protect your sleep. Simple bottom dial…

Custom Mini Mac Build Wondermac
The front bezel required some custom work, which he solved by designing and 3D printing a black bracket to put the Waveshare display in place, cleaning up a bit of plastic in the process to ensure everything fit together smoothly. The original clock’s screws end up holding everything together. As an optional extra, you can sandwich the original’s old LCD layer between the lens and the Waveshare screen to maintain the real border look, albeit this will cost you a sliver of useful screen space. When all is said and done, the finished piece appears to be so beautifully put together that it could have come directly from the factory.

Custom Mini Mac Build Wondermac
The real magic comes from the software, Raspberry Pi OS, notably the 32-bit version, which is stored on a fancy 32GB microSD card. After setting up the essentials like Wi-Fi and SSH, he installed the display drivers and adjusted the output to match the Mac case’s portrait orientation. The big event, however, is Mini vMac, a lightweight emulator that replicates ancient Macintosh computers in one fell swoop. Unfortunately for the project, newer versions were too hefty for the Pi Zero 2 W, so he reverted to an older release that he compiled from source. The laptop then boots directly into System 7 after loading a Mac ROM file and some system disk images, ready to run some vintage apps or simply sit there looking nice with one of those mesmerizing After Dark screen savers.

Custom Mini Mac Build Wondermac
Wondermac operates as a headless machine, displaying its replicated desktop on that little screen, essentially serving as a constant desk ornament. It uses very little power and is extremely silent. Overall, it cost him roughly $100, depending on where you can obtain the Maclock and parts. He’s retained a repository of all the software phases on GitHub, from getting started to mucking around with compilation notes, though he admits the project isn’t seeing much active activity right now.

Can A Scan Tool Kill A Car?

Published

on

It’s no real secret that modern-day cars are basically a collection of computers on wheels, which also means that we get all the joys of debugging complex computer systems and software with cars these days. Rather than a quick poke under the hood to rebuild a carburetor and adjust the engine timing by hand, you’ll be pulling out a scan tool to gain access to the computer and figure out why the darn thing won’t start after someone else used a scan tool on it, as happened to [DiagnoseDan].

The question was whether the third-party scan tool that was used by the owner had done something to the software settings that would prevent the engine of this 2012 Renault Megane RS from starting, such as erasing keys, or if it was something more subtle. With no stored fault codes and the engine having healthy fuel, spark, and cam sensor readings, the conclusion was that the ECU was not doing its fuel injector things for some reason.

Ultimately, the root cause was that the ECU had been modded, with a re-mapping performed in 2020, meaning that the scan tool that [Dan] was using couldn’t properly interact with the ECU. Reflashing the ECU with the original manufacturer’s firmware was thus the next step, which is pretty involved in itself.

Reinstalling the OS on the car proved to be the solution. Likely, the modded firmware had stored some fault codes, as the ECU normally doesn’t start the engine if there are active codes stored. The third-party scan tool was thus likely blameless, but the inability to just clear fault codes was the real issue.

You Asked: TV brightness fatigue, Samsung’s format choices, and the best TV for bright rooms

Published

on

On today’s episode of You Asked: Can we give it a rest with pumping up the TV brightness? Why is Samsung adding Nvidia G-Sync support but not Dolby Vision? And what type of TV will work best in a room with wraparound windows?

Can we stop pumping up TV brightness?

@allclear4115 asks: I’m depressed about TVs nowadays.. Not because they’re too bright, but because they can’t be tamed at all. Rest in peace, dark room!

First off, I definitely understand the brightness fatigue. Everything seems to be “X times brighter than the previous generation” or “brightest ever!” The claimed Nits, the measurement for brightness, is all over the box and the marketing. It’s just everywhere you look, and it can be exhausting.

But I think one of the reasons we see brightness being pushed all over the place is that it’s one of the ways manufacturers can show the most improvement year after year.

Take OLED TVs, for example. The large panels we know now have been around for more than a decade, but they certainly weren’t always this bright. Even as few as four or five or six years ago, they weren’t hitting the levels they are now. And as we’ve talked about a lot, that overall brightness mainly helps with contrast against pure blacks of OLED and peak highlights having the sparkle that makes a viewing experience really special.

Advertisement

With a lot of Mini LED TVs, that increased brightness means being able to overpower ambient light in bright rooms and even sunlight. So brightness does bring some notable quality-of-life improvements.

But that doesn’t mean they aren’t tamed. In fact, some TVs have specific picture profiles for making a pleasurable viewing experience in dark rooms. Hisense, for example, has Theater Day and Theater Night modes. You can set one to have the brightness juiced up during the day to overpower ambient light. And at night, when you don’t want the TV lighting up the entire room, you can turn it down quite a bit.

It’s a similar story for a lot of TVs we talk about on this channel. While they can get very bright and reviewers love to talk about that, they also come with lots of settings that can be adjusted and tailored for what suits you best.

So again, I get where you’re coming from, and I’m sensing a little bit of sarcasm there too. I just don’t think TVs are too bright unless you want them to be. And personally, I’d rather have some room to spare on the bright end than finding my TV too dull when the sun’s out.

Why G-Sync but not Dolby Vision?

Parker Tyler asks: So they’ll pay the licensing for G-Sync, but they won’t for Dolby Vision?

The frustration from Samsung not supporting Dolby Vision continues, and I’m kinda torn on it. I’ve seen the improvements that Dolby Vision 2 brings, but I also have a Samsung Mini LED TV at home that I watch every day without Dolby Vision and have zero complaints.

And I’d imagine a lot of Samsung OLED owners feel the same way. Those QD-OLED panels on the high-end models bring a more colorful punch than most of the competition, and HDR 10 and 10 Plus are nothing to scoff at.

I’m just guessing that Samsung doesn’t see Dolby Vision as enough of an “upgrade” to put it in their TVs. And they sell tons of units every year. So a good chunk of the market also agrees.

For gaming, on the other hand, I would assume having Nvidia G-Sync gives more to that crowd than Dolby Vision does to the general audience. I’m also assuming they’ve done the research and see that adding that feature would sell more of their OLED TVs to gamers.

Advertisement

They’ve also doubled down with HDR 10 Plus Advanced, a new format that boasts great picture control through enhanced metadata. Sound familiar? Safe to say Dolby Vision isn’t coming to Samsung anytime soon. But at least they’re servicing the rest of the market with gaming upgrades.

What’s the brightest TV for a room with wraparound windows?

@YeCannyDaeThat asks: I have a really bright room with wraparound windows. Which is the brightest type of TV?

The brightest type of TV that you’ll find most available is Mini LED. And in that scenario with wraparound windows, especially if there’s a window behind the TV as well, you’ll definitely want to look at some of the brightest available.

TCL and Hisense make some really great options. Think TCL QM8K or the Hisense U8QG. You can also find these in some large sizes to really help the TV stand out among the light around it. And since those are 2025 models, you can probably get them for a really good price right now.

Sony’s Bravia 9 is another great pick for a bright room. It also does a great job holding its contrast at high luminance levels.

I haven’t seen it with my own eyes, but TCL also has a QM9K that looks insanely bright, rated to hit up to 6,500 nits with 6,000 dimming zones. It’s overkill in most scenarios, but maybe not in yours?

Advertisement

I also shouldn’t slight OLED options here, since there are a couple that I think would be suitable for bright rooms. Samsung’s S95F and its anti-glare screen do great battling reflections. LG’s G5 has also stepped up its game in terms of brightness compared to previous models.

You’ll have to see which fits your budget, but like I said before, I think if you can get one of those bright TVs in a bigger size, it’ll really help it overcome the light in your room.

How to get into a16z’s super-competitive Speedrun startup accelerator program

Published

on

Without a doubt, one of the hottest new startup accelerators in tech right now is Andreessen Horowitz’s Speedrun program. Launched in 2023, the accelerator has an acceptance rate of less than 1%. In a January blog post, the program said that over 19,000 startups pitched and fewer than 0.4% were accepted into the latest cohort. 

The program used to focus on gaming startups, then expanded into entertainment and media, and is now a “horizontal program,” Joshua Lu, the program’s general manager and a partner at a16z, told TechCrunch. Today, founders of any type of startup can apply, and the program runs for about 12 weeks in San Francisco. It once had a program in Los Angeles, but Lu said the focus will be on SF from now on. 

There are two cohorts a year, and around 50 to 70 startups are accepted into each. The program invests up to $1 million into each company, though the downside is that it’s a bit pricey. It typically invests $500,000 up front in exchange for 10% of the startup’s company via a SAFE note, and another $500,000 if the next round is raised within 18 months, at whatever terms agreed to by the other investors.

In comparison, Y Combinator typically takes a fixed 7% of the company for $125,000, with another $375,000 “invested on an uncapped MFN safe.”

Speedrun said its program is more “equity expensive” because of what it offers founders. It provides them with access to a16z’s advisory and business networks that assist with tasks like go-to-market, brand development, media strategy, and talent sourcing. Plus it offers the startups perks like $5 million in credits to vendors such as AWS, OpenAI, Nvidia, and Deel.

Given the high interest, and low acceptance rate, TechCrunch spoke to Lu for some tips on how startups can best stand out. The latest cohort began in January and will end in April with a Demo Day. Applications for the next cohort open in April, though it looks at off-season applications year-round, Lu said. 

Focus on the founding team  

Speedrun focuses on early-stage startups. Because of this, they really examine who is on the founding team and whether their skills complement each other, Lu said.

“That doesn’t mean one has to be technical and one has to be commercial and one has to be marketing,” Lu said. It means that “we prefer not to see any glaring holes in capabilities or interests. We want the founding team to be self-aware and for that to be part of the hiring plan.”  

Advertisement

They also like to see teams that have worked together before or have a shared history. 

“There are lots of things that a founding team has to navigate in their startup journey and having a bit of pattern recognition, being able to work with each other, knowing how to disagree and how to come out the other side of a disagreement, those are all things people on founding teams with shared histories have an easier time with, on average,” he continued. 

Even though AI has lowered the barriers to building software, it’s still incredibly helpful for a founding team to be technical, Lu said. At the same time, because AI has made it much faster to build and validate hypotheses and get a product out there, Lu said the Speedrun team likes to see when a startup already has a little bit of market validation or traction for their product.

“Speedrun as a program is really great at helping teams pour gasoline on a very small spark or fire,” he said. “We look for teams that have endeavored to build and try to show us that there’s a little spark we can fan the flames on.”

Limit the market “theory”

Lu said one common mistake founders often make in the application process is spending too much energy talking about the market theory or why there is a defined problem and why their solution is the right one. “All of that may be true,” he said.

At the same time, he added, even the biggest, most successful tech companies faced unexpected blockades when they were young, sometimes even pivoting completely. What a company thinks it’s going to build at the beginning isn’t necessarily what will make it successful at the end.

“What we really want to hear about is why this founding team is really good together,” he continued, “why they’re a great founding team, the best possible founding team to solve this particular problem.” And then on top of that, any validation on the idea itself. 

It’s okay to use AI for the application, but…

Lu said the program encourages every founder to use AI to “clean up” their application. He said there is now no excuse for grammar errors or misspellings given the rising sophistication of AI tools. He also said AI can help founders sort out their thoughts, making them clearer, more concise, and more coherent.

But if AI did all the work in explaining the startup, that may backfire. If a founder makes it to the next round, it will be a live video-call interview. “At that point, their live narration explanation skills are going to be put to the test,” he said. So founders should be prepared to talk cogently about their startup without the help of AI.

Only about 10% of founders make it to the video-call stage. There are typically two to three investors on the judging panel at a time.

After the live interview, the team typically conducts a few more screening calls with the founders, and then a final decision on the cohort is made.

Be greedy to network

There are, of course, other accelerator programs for startups to choose from. Lu said Speedrun itself was inspired by some of these other programs.

Still, he said, this accelerator prides itself on giving founders access to a large, specialized operating team. In fact, he said the best teams that get the most out of the program are the ones most “greedy about getting exposure to the amazing people and programs” Speedrun has to offer. 

Lu listed off just a few points: a16z has around 600 people, and 10% of that staff is on the investment team, he said; everyone else is an operator who supports the companies the firm works with. As a result, founders in Speedrun will have access to experts who can help with marketing, banking, finance, management, and many other functions. So it helps to know who the startup wants to connect with and why. 

“We tell founders that come through the program, what you get out of Speedrun is what you put into it,” he said. “We think founders who want to take advantage of world experts in many different domains early in their startup journey would be really smart to choose us.”

Advice from a founder in the program

Founder Mohamed Mohamed, who is in the recent cohort, just announced a $5 million raise for his proptech startup Smart Bricks led by a16z’s Speedrun. He was attracted to the program because he said it stood out as one of the few “explicitly designed for co-founders working on frontier AI applications,” and he picked it because he wanted a program that would allow him to “stress-test an ambitious technical vision.”

Mohamed said he treated the application like an internal strategy memo rather than a pitch. “Instead of polishing buzzwords, we focused on clarity — the real problem, why it’s structurally hard, and why our team is unusually well-positioned to solve it,” he said. “We were explicit about what was working, what wasn’t, and where we needed help. I think that honesty and clear articulation of why this problem matters” is what helped the company in the application process.

He called the whole process “rigorous but refreshingly thoughtful,” and said it was designed to understand how founders think, not just what they have built so far. “The conversations went deep into product architecture, data strategy, and long-term ambition. It felt closer to a partner-level discussion than a typical accelerator interview, which was a strong signal for us,” he said.

His overall advice is to be “intellectually honest and precise.” For example, he said in his application he avoided “over-optimizing” for the sake of hyping up his company. “If you’re vague, derivative, or overly defensive about your idea, it shows quickly. Don’t try to sound bigger than you are; clarity about where you actually are is far more compelling than inflated narratives,” he said.

In the end, “Speedrun isn’t looking for perfect companies; they’re looking for founders who can reason clearly about complex problems and build with conviction,” he said. “Articulate the hard parts of what you’re doing and why they’re worth tackling. Depth beats polish every time.”

Best Vegan Meal Delivery of 2026: We Tried the Top Vegan Meal Kits

Published

on

When trying to find a vegan meal delivery service, several factors should be considered to find your perfect fit. 

Prepared meals versus meal kits: Prepared meals come ready to heat in the microwave or in a pan on the stovetop. Meal kits, on the other hand, provide all the ingredients and instructions you’ll need to prepare the meals yourself. Though prepared meals are easier and take less time, meal kits may be good for those who like cooking or want to learn to cook.

Fresh versus frozen: On this list, we only have one meal delivery service that offers fresh meals you keep in the fridge for eating or heating: Thistle. All other prepared meal delivery services offer preprepared meals that are frozen.

Dietary restrictions: If you have certain dietary restrictions, you’ll want to ensure that the service you choose caters to all of them. Some services are strictly vegan, while others are vegetarian. If you’re gluten-free, counting calories or carbs or want high-protein meals, those are also factors you should consider. 

Cost: Out of the services tested for this list, costs range from $6 to $18 per serving. Before choosing a meal delivery service, you will want to determine your budget and what you’re willing to pay for time saved and convenience. Also, are you willing to pay more for meals that are already prepared versus meal kits you make yourself?

Variety: Depending on your diet, only a certain number of meals may be offered per week. Each meal delivery service should allow you to view its menus a few weeks in advance, so you can take a look at how many meals you’ll have to choose from. If you plan to rely on this service for most of your meals, you’ll want to ensure it caters to your specific diet with a wider variety of dishes.

Number of servings: If you’re looking for a meal delivery service for a couple or family, check to see how many servings are offered. Meal kits are likely to offer a greater number of servings (around four to six), while prepared meals are better suited toward individuals.
