31. Putting email in its place with Emacs and Mu4e
I had a few free hours recently and decided to have a go at a long-simmering idea: To improve how I manage multiple email accounts. As someone who struggles mightily to cope with distractions (I have the attention span of a gnat), I was hoping to consolidate several separate interfaces into one, simpler, less distracting, more focused client.Sadly, I wasn't quite successful -- my work emails remain out of reach. But I learned a lot and ended up in at least a better place.

35. 10 Years of Let's Encrypt
On September 14, 2015, our first publicly-trusted certificate went live. We were proud that we had issued a certificate that a significant majority of clients could accept, and had done it using automated software. Of course, in retrospect this was just the first of billions of certificates. Today, Let’s Encrypt is the largest certificate authority in the world in terms of certificates issued, the ACME protocol we helped create and standardize is integrated throughout the server ecosystem, and we’ve become a household name among system administrators. We’re closing in on protecting one billion web sites.

43. Linux CVEs, more than you ever wanted to know
It’s been almost 2 full years since Linux became a CNA (Certificate Numbering Authority) which meant that we (i.e. the kernel.org community) are now responsible for issuing all CVEs for the Linux kernel. During this time, we’ve become one of the largest creators of CVEs by quantity, going from nothing to number 3 in 2024 to number 1 in 2025. Naturally, this has caused some questions about how we are both doing all of this work, and how people can keep track of it.

48. Passing the Torch: James Gross on the Next Chapter of Micromobility Industries
When people talk about micromobility, the focus tends to stay on vehicles, better scooters, longer-range batteries, and safer brakes. But the biggest transformation in the industry is happening somewhere far less visible: in charging.

51. Apple's Slow AI Pace Becomes a Strength as Market Grows Weary of Spending
Through the first six months of 2025, Apple was the second-worst performer among the Magnificent Seven tech giants, as its shares tumbled 18% through the end of June. “It is remarkable how they have kept their heads and are in control of spending, when all of their peers have gone the other direction,” said John Barr, portfolio manager of the Needham Aggressive Growth Fund, which owns Apple shares.

53. Operando interlayer expansion of curved graphene for dense supercapacitors
Supercapacitors deliver high power but are limited in compact applications by low volumetric energy and power densities. Two-dimensional materials like graphene, despite their high packing density, are hindered by poor ion transport kinetics. A rapid thermal annealing step generates unusually curved turbostratic graphene crystallites, integrated and interwoven within disordered domains in micron-size particles to yield multiscale graphene. Ion insertion into the interlayers enables precise pore-ion matching and partial charge transfer, enabling a high Brunauer-Emmett-Teller surface area-normalized capacitance of 85 µF/cm2. Here, we show that multiscale graphene exhibits rapid ion transport dynamics within the curved crystallites and disordered domains. When the thin electrodes are assembled into symmetric pouch cell devices, they deliver a stack-level volumetric energy density of 99.5 Wh/L in ionic liquid electrolytes and 49.2 Wh/L in organic electrolyte with a high power density of 69.2 kW/L at 9.6 Wh/L. Supercapacitors are high-power energy storage devices that suffer from poor volumetric performance. Here, the authors demonstrate that unusually curved graphene crystallites exhibit rapid ion transport dynamics and enable the fabrication of thin electrodes for compact energy and power delivery.
