The tech layoffs continue

A quarter of a million tech workers were laid off last year from the likes of Google, Amazon, Meta, Microsoft, and thousands of other big and small companies in the industry. And it looks like this year is not going to bring any relief. Google just announced more layoffs, Twitch cut 35% of staff, Discord is axing 17%, and Unity is cutt...

Google Cloud cuts egress and promotes cloud exits

The absurd egress fees charged by major hyperscalers have been one of the biggest impediments for companies to leave the cloud. We’ve been preparing for our own departure from AWS S3 at 37signals, and the price for taking our data elsewhere is in the crazy-land region of $300,000-$400,000! So imagine my surprise seeing the announcement...

Apple approves the HEY Calendar

I’ll admit it was a bit cheeky to make our new HEY Calendar app “do something” by including Apple’s own history as a preview for people who don’t have an account. And I didn’t give the gambit better than 30% odds of succeeding, but lo and behold, it did! Apple has approved our app, and it’s now available in the App Store! What a relief...

We’ve resubmitted the HEY Calendar app to Apple

Apple waited until end of business on Friday to send us the formal rejection of the HEY Calendar app. It seems they love to play these little games to try to drown any controversy with the cover of a weekend. But we don’t roll over that easy, so the team worked through the weekend to prepare a new build to appease the App Store’s bully...

Pessimism is on the retreat

“I feel it in the feed. I feel it in the discourse. I smell it in the vibes. Much of the pessimism that once was is lost, for none now wish to remember it.” We’ve lived through some strange years in the recent past. Much stranger than any I can remember since my earliest, solid memories of the broader world from the mid-80s. I’m not go...

Keeping the lights on while leaving the cloud

It was a big year for ops at 37signals. In 2023, we moved seven major applications out of the cloud. Including HEY, our email service, which had been born there, and has an extremely high level of uptime criticality. Moving out of the cloud could not interfere with that obligation, and thankfully it did not. In 2023, HEY had a stellar ...

Happiness is never having to ask for permission

If there’s one value Jason and I put above all else in business, it's independence. The freedom to make our own choices, good or bad, without ever having to ask anyone for permission. Not from investors, not from naysayers, not from platform gatekeepers. It’s why we’ve built our business on the web. The greatest, freest computing platf...

Apple rejects the HEY Calendar from their App Store

There should at least be a standard of double jeopardy when it comes to the app store monopoly regimes. If you’ve managed to overturn a rejection of your service once, they can’t come after you on the same service again later. We could have used that today! But unfortunately there is no rule of law with the app stores, except that of t...

The reality of the Danish fairytale

Denmark has long ranked high on the list of societies that American liberals dream about turning the United States into. And for many good reasons. Education is state-funded, and students are even paid a stipend to go to university. Health care is equally free of individual charge, and there’s generally a robust social safety net for u...

A writer's Ruby

Programmers at large seem eternally skeptical of style. And I’m not just talking about the stereotype of nerds in uncoordinated outfits or using pocket protectors. But style in the broad sense of aesthetics. Many appear imbued with fundamental opposition to the idea that how something looks should even matter. That somehow such a focus...

New year, new calendar

We’ve spent the last year tackling the number one request for our email service HEY.com: Adding a calendar! And now, in celebration of the new year, it’s finally ready, and we’re rolling it out to the first customers starting today 🎉 See, it turns out that lots of people would love to switch their email to HEY, whether it’s because the...

We’re so back

Under the old Twitter regime, politics seemed to seep into everything, especially tech talk. There was scarcely a programming or product topic that couldn’t be turned into a struggle session on account of some perceived transgression or privilege. It was, to use the trauma language of those days, exhausting. It also simply seemed like ...

Picking a purpose

Victor Frankl wrote Man’s Search for Meaning after surviving a concentration camp during World War II. He observed the outer extreme of what happens to people who no longer have a WHY to live for. They’d wither and die in the camp. Even the most dire rations and punishing labor could be survived by many, as long as they had a purpose s...

Finished software

One of the driving aspirations behind once.com is the notion that not all software needs to evolve forever. We’ve become so used to digital services being malleable that we’ve confused the possibility of software updates with their necessity. Some software can simply be finished, and a lot would be better if it were. That’s basically t...

Commit to competence in this coming year

It’s that time of year where people often start thinking about new year’s resolutions. I want to lose 10 lbs, I want to read more books, I want to x, y, and z. Often, it’s just a fantasy. They’re not actually going to lose 10 lbs or they might order some more books but never read them. But at least there’s a spark of hope there. A fund...

Challenging the guardians of the paradigm

I swear the intention isn’t to constantly start fights with guardians of every sacred paradigm in the tech world. To be honest, it’s been a bit exhausting at times to concurrently argue on at least three major flanks. But that’s just how this year has turned out, given the work we’ve been pursuing. Whether it’s telling people that you ...

ONCE #1 is entirely #nobuild for the front-end

The dream has come true. It’s now possible to build fast, modern web applications without transpiling or bundling either JavaScript or CSS. I’ve been working towards this personal nirvana ever since we begrudgingly started transpiling and bundling assets in the late 2000s. Browsers just weren’t good enough back then to avoid it. But th...

Five big open source gifts from us

It’s been an incredibly productive year at 37signals. Perhaps our most productive one yet, in terms of total number of product improvements, new product developments, and open source extractions. But it’s only by looking back at the work from a distance that you can really appreciate it. So allow me to do that here. To appreciate the b...

The Big Cloud Exit FAQ

Just over a year ago, we announced our intention to leave the cloud. We then shared our complete $3.2 million cloud budget for 2022, and the fact that we were going to build our own tooling rather than pay for overpriced enterprise service contracts. The mission was set! A month later, we placed an order for $600,000 worth of Dell serv...

Patek levels of finishing

We’re in the final phase of getting the first ONCE product out the door.

That’s usually where the temptation to cut corners on internal quality beckons, but we’ve handcuffed ourselves to the virtue of beau...

Native mobile apps are optional for B2B startups in 2024

I continue to see new B2B software startups struggle with native mobile apps. Consumer software makers can usually start by going all-in on a single platform, but for business tools, that’s rarely an option. So they must face the tall task of tackling web, iOS, and Android at the same time. Hence the proliferation of toolkits like Reac...

The early bird sees the sunrise

I’ve found that you eventually get bored or at least used to every form of material trapping you can buy. Cars, watches, cameras, computers, whatever. It’s not that fancy stuff stops being nice, but it does stop being wow. That’s the essence of the hedonic treadmill. But do you know what never gets old? Nature. And I mean nature in the...

What is HiFi

I grew up in a home where music was always playing. My father repaired electronics, so an endless stream of speakers, amplifiers, turntables, and TVs passed through the household. And all of it had to be tested, of course. At max volume. Sometimes at odd hours. While that was frequently a bit of a nuisance, it did seed a deep appreciat...

The origin of Ruby on Rails

I can't thank Honeypot and Carolina Cabral enough for the producing The Rails Documentary that was just released today. Looking back on those early, formative years of Ruby on Rails with Tobi, Jamis, Jeremy, and Jason was actually kind of profound. I usually don't spend much time looking back, so for once to stop and marvel at how we g...

From Lamborghini to Pagani, Porsche to Ferrari, Aston Martin to Bentley, I have owned and loved them all. A+ use of lottery money, would do it again! It's against all these delig...

Workfeed goes to America

During my three years in Denmark, I invested in five local startups. All on the premise that we'd work towards becoming profitable, remaining in the country, and avoiding the VC timebomb. The one that has already fulfilled all the objectives is Workfeed, and now they're ready to take on the American market. It's a proud moment! Workfee...

Negative visualization in practice

The most counterintuitive of the Stoic mental exercises is that of negative visualization. Willfully imagining all manner of terrible things that might befall you, but haven't yet. Described like this, it sorta sounds like a fancy word of anxiety, but if you look closer, it's in fact its opposite. The point of visualizing the consequen...

X celebrates 60% savings from cloud exit

Musk has taken a cleaver to the costs and complexity at X. It hasn't always been pretty, but it sure has been effective, and in the process, he's proven his detractors wrong time and again. Not only has the site stayed up, despite hysteric proclamations that it would crater soon after his personnel changes, but X has been able to incre...

Buying the seller

We've just moved the 37signals podcast to Buzzsprout. Podcast hosting is to some extent a commodity market, so this was less about pining for a specific feature or even working to reduce the bill. This was about buying from Tom Rossi, the technical cofounder of HigherPixels (who make Buzzsprout), and his team, because we'd just prefer ...

The open source gift exchange

I love writing and sharing code as open source, but it's not an abstract act of pure altruism. The first recipients of these programming gifts are almost always myself and my company. It's an intentionally selfish drive first, then a broader benefit second. But, ironically, this is what's made my participation in the gift exchange of o...
