Conversely, on the receiving end, if you aren't somebody who's made a business out of being a contractor then taking some company's money to do a specific piece of work also seems like too much hassle and overhead to be worth

I write code somebody else wants and get paid for it as my day job. It happens to be open source. Some people write the code they want to write, but keep it closed-source. So I don't think your contrast quite works. I think some of the

True, but I think it's easier economically and politically to get from "aging 19th century network" to "modern network" because you can upgrade it piecemeal tackling the worst bits first, compared to starting from &

The Japanese text in that PDF doesn't say anything about cron. It just says that the script was overwritten "while there was an executing script in existence" ("実行中のスクリプトが存在している状態で"), and doesn't say whether th

Language changes slowly but constantly: words evolve new sentences, new phrases are coined, others become less current. The OED is so big that the only practical way to revise it is continuously, a few entries at a time. Every quarter there

If you're in the UK then many public libraries have subscriptions to the OED which include "remote access". This means you can log in from anywhere just by putting your library card number into the OED's login form. So c

Ah, so a Transmeta style approach? That's certainly feasible, in the sense that their technology worked, but I think it would be tricky at best to match the performance of the more standard do-it-in-hardware approach.

Is there much benefit from delaying the zeroing to first-write rather than first-read (which I think is effectively where Linux does it)?

At least some of this complexity and abstraction layer provided by the hardware is done so that the same binary can run on multiple different implementations, though. If you expose low level instructions corresponding to the specific CPU im

Thanks for the heads-up about ps4 bluray playing. Apparently (assuming reddit posts to be correct) the internet requirement is a one-time thing where it downloads codecs, and Sony is supposedly doing it this way so they only pay the codec l

I'm not sure visualization is necessary -- I can't visualize much at all, and definitely don't visualize words, but misspelt words are immediately obvious to me. They don't look right -- so maybe you need to have a memor

Because, as with all dictionaries except the absolutely massive complete editions, you can only put in so many words (this particular volume has 6,000 entries and is aimed at 7-8 year olds). In a related Guardian article somebody from the O

Yes, or send a fake mouse move. It does this already when running on Windows or OSX; there's an open issue for adding the Linux host support: https://github.com/haimgel/display-switch/issues/27 I reckon

Extremely nerdy sub-detail -- M-profile actually has all the handling for the Thumb-to-Arm switch architecturally, with the LSB of a branch target being significant and a T bit in the PSR to tell you what mode you're in, which you can
435.
by pm215 5y ago
Why would a thumb/arm switch invalidate the caches? It's just an interworking branch, it isn't even a context switch.

If you're designing a single CPU that definitely has a simple pipeline, branch delay slots are maybe justifiable. If you're designing an architecture which you hope will eventually be used by many CPU designs which might have a va

I didn't say "take pride in your code because you own it", I said that because you feel some pride in what you've made you feel some sense of investment in it. And I wasn't trying to speak to legal ownership but to

Two reasons, one technical, one social. Firstly, the original developer probably spent more hours thinking over and working on that bit of code than you have -- so maybe they had a good reason for doing it the way they did. You won't k

AIUI the term first became common in the mid-1990s; Labour at the time were in opposition, and I have read Labour were very fond of using the term because it was wider and easier to apply to any even slightly-murky thing a Tory MP had got i

Does your memset version beat QEMU's plain-old-C fallback version ?

Interestingly, we used to have a special-case aarch64 version, but we dropped it because the C version was faster: https://gitlab.com/qemu-project/qemu/-/commit/2250d3a293d36e... (Might or might not stil

Yep, for paper documents I have a 4-drawer filing cabinet, which I got cheap second hand years ago. It takes up some space, but the benefits over the years have been huge: - I always know where to look for a document (even in the worst

The architecture name is also Arm. A lot of people never got the memo about the recapitalization of the company name in 2017, including, apparently, the journalist who wrote this article. The text which is a quote from the company spokesman

It's a bit fuzzy and I don't think there's a single universally agreed on line. See the discussion in the "Microcode in RISC?" section of Ken's analysis of the ARM1 at http://www.righto.com/2016

I think we'd expect to see vestiges of the no-longer-outwardly-visible horn in the skeleton and perhaps during fetal development, like with human tails.

For UK travel it depends a bit I think - a daily commuter's experience will be a lot different to that of somebody who is making off-peak leisure trips. For the latter my experience is that there's rarely crowding (especially in t

Hmm? The A64 instruction set includes instructions to convert from floating point to integer and set the Inexact FPCR flag if the conversion isn't exact, which is pretty much exactly the operation we want here (it's one of the var

In normal userland you have lots of RAM, and the whole virtual address space to play with, and you can make any part of it you like either read-only or read-write, so it doesn't matter much if you end up with either (a) a fixed offset
