netlab release 25.12 (25.12.02 to be exact – I had a few PEBCAK moments) was published last Friday. Here are the highlights:
Note: This post was updated with additional details regarding AWS Lambda.
Last year we announced basic support for Python Workers, allowing Python developers to ship Python to region: Earth in a single command and take advantage of the Workers platform.
Since then, we’ve been hard at work making the Python experience on Workers feel great. We’ve focused on bringing package support to the platform, a reality that’s now here — with exceptionally fast cold starts and a Python-native developer experience.
This means a change in how packages are incorporated into a Python Worker. Instead of offering a limited set of built-in packages, we now support any package supported by Pyodide, the WebAssembly runtime powering Python Workers. This includes all pure Python packages, as well as many packages that rely on dynamic libraries. We also built tooling around uv to make package installation easy.
We’ve also implemented dedicated memory snapshots to reduce cold start times. These snapshots result in serious speed improvements over other serverless Python vendors. In cold start tests using common packages, Cloudflare Workers start over 2.4x faster than AWS Lambda without SnapStart and 3x faster than Google Cloud Run.
In this blog post, we’ll explain Continue reading
Go’s embed feature lets you bundle static assets into an executable, but it stores them uncompressed. This wastes space: a web interface with documentation can bloat your binary by dozens of megabytes. A proposition to optionally enable compression was declined because it is difficult to handle all use cases. One solution? Put all the assets into a ZIP archive! 🗜️
The Go standard library includes a module to read and write ZIP archives. It
contains a function that turns a ZIP archive into an io/fs.FS
structure that can replace embed.FS in most contexts.1
package embed import ( "archive/zip" "bytes" _ "embed" "fmt" "io/fs" "sync" ) //go:embed data/embed.zip var embeddedZip []byte var dataOnce = sync.OnceValue(func() *zip.Reader { r, err := zip.NewReader(bytes.NewReader(embeddedZip), int64(len(embeddedZip))) if err != nil { panic(fmt.Sprintf("cannot read embedded archive: %s", err)) } return r }) func Data() fs.FS { return dataOnce() }
We can build the embed.zip archive with a rule in a Makefile. We specify the
files Continue reading

Selama hampir 160 tahun, Amandemen ke-14 menetapkan bahwa setiap orang yang lahir di wilayah Amerika Serikat berhak menjadi warga negara Amerika. Aturan itu hanya membuat sedikit pengecualian. Misalnya untuk anak diplomat atau anggota militer asing. Karena itu, banyak orang menganggap aturan tersebut sebagai fondasi utama identitas Amerika.
Namun, pemerintahan Donald Trump memicu perdebatan panas sejak awal masa jabatannya. Ia menandatangani perintah eksekutif untuk mengakhiri hak kewarganegaraan otomatis bagi anak yang lahir dari orang tua tanpa izin tinggal atau berstatus visa sementara. Trump melihat hal tersebut sebagai bagian dari reformasi imigrasi besar. Dia menilai bahwa keamanan nasional selalu menjadi prioritas utama.
Sementara itu, aktivis hak sipil dengan tegas menolak langkah keras tersebut. Mereka menyebut hak kewarganegaraan berdasarkan kelahiran sudah dijamin konstitusi, bukan sekadar kebijakan politik yang bisa diubah secara sepihak. Bahkan Cecillia Wang, Direktur ACLU, menegaskan bahwa tidak ada presiden yang bisa menghapus janji fundamental Amandemen ke-14.
Selanjutnya, banyak pengadilan federal langsung menghentikan perintah eksekutif Trump. Mereka menyatakan tindakan itu melanggar Konstitusi. Continue reading
In this episode of the Hedge, Geoff Huston joins Tom Ammon and Russ White to finish the discussion on the ideas behind DNS over HTTPS (DoH), and to consider the implications of its widespread adoption. Is it time to bow to our new overlords?
This is part two of a two part series. This is a “best of the Hedge” repost.

AWS Graviton5 Strikes A Different Balance For Server CPUs was written by Timothy Prickett Morgan at The Next Platform.
Note: This post was updated to clarify the relationship of the internal WAF tool with the incident on Dec. 5.
On December 5, 2025, at 08:47 UTC (all times in this blog are UTC), a portion of Cloudflare’s network began experiencing significant failures. The incident was resolved at 09:12 (~25 minutes total impact), when all services were fully restored.
A subset of customers were impacted, accounting for approximately 28% of all HTTP traffic served by Cloudflare. Several factors needed to combine for an individual customer to be affected as described below.
The issue was not caused, directly or indirectly, by a cyber attack on Cloudflare’s systems or malicious activity of any kind. Instead, it was triggered by changes being made to our body parsing logic while attempting to detect and mitigate an industry-wide vulnerability disclosed this week in React Server Components.
Any outage of our systems is unacceptable, and we know we have let the Internet down again following the incident on November 18. We will be publishing details next week about the work we are doing to stop these types of incidents from occurring.
The graph below shows HTTP 500 errors served by our network during the Continue reading
Sean Goedecke published an excellent set of recommendations for good technical writing, including:
Based on some emails I received in the past (and the lack of response to the lengthy emails I sent), we should apply the same rules to emails (and all other forms of technical communication).

It was only a matter of time before Marvell was going to make another silicon photonics acquisition, and the $2.5 billion sale of its automotive Ethernet business to Infineon for $2.5 billion has given the company this past summer netted out to about half of the $3.25 billion that the company is shelling out to get its hands on Celestial AI, one of the several upstarts that hopes to hook compute engines, memory, and switches together using on-chip optical engines and light pipes. …
