Apple vs the Law

formularsumo.co.uk — A week ago today I had the pleasure of attending both the Apple and Google DMA compliance workshops in Brussels. More detailed articles on the questions and answers, technical and legal analysis etc will be published over at the OWA blog, where we've just done the first write-up on the Google part. Here though I'd like to focus more on my own experience and personal opinions, and how I feel about some of the gatekeepers' approach to the law... LAW, 1

Postgres LISTEN/NOTIFY does not scale

recall.ai — At Recall.ai, we run an unusual workload. We record millions of hours of meetings every month. Each of these meetings generates a large amount of data we need to reliably capture and analyze.

Btrfs Allocator Hints

lwn.net — From: Anand Jain <anand.jain-AT-oracle.com> To: linux-btrfs-AT-vger.kernel.org Subject: [PATCH RFC 00/10] btrfs: new performance-based chunk allocation using device roles Date: Tue, 13 May 2025 02:07:06 +0800 Message-ID: <cover.1747070147.git.anand.jain@oracle.com> In host hardware, devices can have different speeds. Generally, faster devices come with lesser capacity while slower devices come with larger capacity. A typical configuration would expect that: - A filesystem's read/write performance is evenly distributed on average across the entire filesystem. This is not achievable with the current allocation method because chunks are allocated based only on device free space. - Typically, faster devices are assigned to metadata chunk allocations while slower devices are assigned to ...

The Wet History of Media in the Bathroom

mit.edu — In the 1980s, as Americans were swept up in a fitness craze and growing obsession with personal wellness, self-betterment projects extended from the outdoors to domestic interiors. Bathrooms in particular got larger and larger (some large enough to do cartwheels in), as did bathtubs and showers. Interior designers promoted renovating one’s bathroom to feature the latest high-tech gadgets and encouraged people to reconceive of these spaces as “luxury spas.” These architectural changes imagined that media practices and hygiene practices could seamlessly coexist. Over time, bathroom culture expanded well beyond basic hygiene. WET, 17

Orwell Diaries 1938-1942

wordpress.com — There is evidently trouble in Syria. Handout this morning to the effect that – most unfortunately and much against H.M. Government’s will – General de Gaulle is insisting that Syria is still under a French mandate and it is impossible yet to make a treaty, as in the case of Irak. General de Gaulle’s attitude is considered most deplorable, but as he is, after all, the accredited leader of the Free French and the whole legal position is very obscure (the matter should be decided upon by the League of Nations which unfortunately no longer exists) H.M. Government is unable, etc., etc. In other words the Syrians will get no treaty, the blame for this is placed on our puppet de Gaulle, and if possible we shall swipe Syria for ourselves. When I heard this hollow rubbish trotted out by Rushbrooke-... ORWELL, 26

Measuring the impact of AI on experienced open-source developer productivity

metr.org — We conduct a randomized controlled trial (RCT) to understand how early-2025 AI tools affect the productivity of experienced open-source developers working on their own repositories. Surprisingly, we find that when developers use AI tools, they take 19% longer than without—AI makes them slower. We view this result as a snapshot of early-2025 AI capabilities in one relevant setting; as these systems continue to rapidly evolve, we plan on continuing to use this methodology to help estimate AI acceleration from AI R&D automation 1.

AI coding tools can reduce productivity

secondthoughts.ai — The buzz about AI coding tools is unrelenting. To listen to the reports, startups are launching with tiny engineering teams, non-programmers are “vibe-coding” entire apps, and the job market for entry-level programmers is crashing. But according to a METR experiment conducted in the spring of 2025, there’s at least one cohort that AI tools still aren’t serving. CODING, 30
