I think the primary measure is simply "think about it in advance". The major requirement is just to make sure that multiple people have the necessary admin accesses; this is seldom technically tricky. You just need to take an afte

TSB's systemic failure was a result of trying to clean up their tech debt (and dependency on Lloyds' systems), though -- the old systems were working fine for them (and continue to work fine for Lloyds), not falling over all the t

You have to be a little careful with trapping SIGSEGV to implement funky behaviour though -- it's easy to write a handler that works for the expected case, but harder to write one that doesn't result in incredibly confusing behavi

Yes, I loved the catalogues of that era too, especially since they commissioned SF art for the covers: http://70sscifiart.tumblr.com/post/166105106512/maplin-catal... In the modern era their shops were useful for

I suspect in a lot of cases reading the Lions commentaries was not purely for fun. The original audience (Lions' students) were doing it as part of their university course. Many of the contemporary readers would have been reading it be

Yes. Most UK libraries have a setup so that their members can use the online OED from anywhere on the internet (you just have to enter your library card number). It uses cookies so you don't have to log in every time you want to look u

dpkg won't allow one package to overwrite a file from another unless you pass it --force-overwrite, which is not the default.

Mmm. In particular it notes that (a) in previous years the assistant had been only expected to do the first two parts of the job description and (b) after Lorch turned it down they ended up dividing the work between four assistants. So it&#

The major problem with the email-patches workflow is that it is a pretty poor experience for the new and occasional contributor, who will generally find that their email client makes a complete pig's ear of their patch. What I'd r

Note that the Cortex-M chips implement only the Thumb/Thumb2 encodings. Those have different rules for encoding immediates -- the rules this article describes are for the 32-bit ARM (A32) encoding.

Perhaps you could mention the motivation for the trick in the readme? My initial reaction was "either this is an april-fools style joke, or it's a cute but pointless trick", and it wasn't til I got to the bottom of the H

Judging by the descriptions, these VirtualBox bugs are all in the device emulation, host-to-guest communications framework and so on, so they would apply equally whether the VM was using virtualization hardware or instruction emulation. Thi

Yeah, that has hit upstream now. It needs support in both the frontend and the backend so only some host/guest combos will enable it, but arm-on-x86 should now multithread by default for smp guests.

I think it's worth noting that this isn't actually emulating a Raspberry Pi. The option "-M versatilepb" to QEMU tells it to emulate a VersatilePB, which is an Arm development board that's now a decade or more old.

The RM Nimbus was 186-based ( https://www.thenimbus.co.uk/range-of-nimbus-computers/PC-186 ) -- UK people might remember it as it was pretty popular in schools in the late 80s/early 90s. It wasn't fully PC comp

Here's a recent pet annoyance of mine: if you have a lot of output from a command, so you pipe it through less, and then use X cut-and-paste to copy a multiline chunk of it to another terminal, it seems to be arbitrary whether it paste

I think one reason is that if you already know a project as a user you're a long way up the learning curve for understanding it. You know roughly what its feature set is, you know how new features would fit in with the existing ones, y

You can regenerate, and indeed you have to if you need to add support for a new cpu architecture, for instance. Debian has support in its packaging for making it easy to regenerate configure scripts as part of the package build for this rea

True, but there's some merit to being consistent with the naming used by the toolchain (which appears in things like cross compiler binary names) and the name printed by the linux kernel in 'uname -a')...
