You mean the total lack of comments didn't help? ;-) SPARC has two attributes (I hesitate to call them features) that this code interacts with: register windows and a delay slot. Register windows are a neat idea that leads to some chal

I have a uniquely soft spot for SPARC, having written and disassembled a bunch of SPARC early in my career. If this is its swan song, I'll take the moment to share some code the takes advantage of the odd (today) delay slot architectur

What is the latest on RAID-5/6 support for BTRFS. RAID-Z has its issues (saying this as the triple- and double-parity author), but it's been stable.

@dlurton since you seem to be speaking for the PartiQL team on this (congrats on the launch!): The reference implementation is open source; what's the plan for the language spec? Is that something that AWS is going to own and control?

Really cool project, @wing328hk. Congrats on the new release.

Biased, but also extremely excited for this. What catches our collective attention are systems we hate, systems that suck, systems that fail--or systems too new to know. It's refreshing to consider systems established and clever enough

The author (me) isn't a Rust expert, but has played with it a bit. Rust, I think, suffers from a lack of empathy with a novice audience. I'm a big fan of Rust and I think it introduces some novel, valuable, and fascinating new con

Engineers who have worked on HFS+ believe that it actually is losing data left and right. I'm inclined to believe that they're right and that most people simply don't notice.

That use of multiple partitions I think qualifies as uncommon which is not to suggest that it's not useful.

The author (me) isn't dismissive; he's skeptical. Siracusa did a great job of upbeat, critical, accurate reviews. Conversely, the coverage of APFS has been inane. A video, a PDF, and some high level docs were shuffled and reworded

COW is great. It has applicability around on-disk consisteny, and it makes snapshots much more coherent. It's also not without downsides such as fragmentation--though that's far far less important on SSDs than HDDs. Apple's f

I'm inclined to agree that 3 years to squeeze out a perfect file system is ambitious to say the best. That said, consider the robustness of HFS+; APFS is blessed with desperate, captive users.

Good catch; thanks.

Yep! They paid me the usual fractional pittance offered to authors. edit: and to be clear I'm delighted and flattered to see my work featured in Ars!

The failure mode of hardware is not all or nothing. A single sector in an HDD or a single page in an SSD can fail and the rest can be fine for years; both HDDs and SSDs have many spares for this expected condition.

Talking to the Apple engineers it really didn't seem to be an issue of computation. They seemed genuine in their belief that they could solve data integrity with device qualification. While I asked them 100 questions they asked me 2: h

Unclear, but a member of the ZFS development team at Apple told me that Giampaolo complained that ZFS would never work on the phone. So the team demonstrated it working on the phone. I know of no obstacles to making it work on the watch oth

This guy (i.e. me) wasn't aware of this functionality in btrfs. Are reflinks commonly used? Yes, I know more about ZFS than the other filesystems mentioned.

Fair enough; and right now cp doesn't use the fast clone functionality, but it assuredly will. I'm not sure 'cat <file >file.dup' is reasonable for most users.

Apple started in 2006 with no deal or coordination with Sun. Later when the FUD started, they were looking for protection from patent lawsuits (i.e. from NetApp), for support and expertise, and, possibly, reassurances around patent clauses
