you can be like "I want to make an app that is both a dating app and a financial management app and a trash calendar" and they'll prompt you back by asking if this is really a good idea

Hello everyone! I’m interested in radio astronomy, archaeoastronomy and SDR. I’m currently looking for hardware and software that work well with an older MacBook Pro.

I’m in QRX for logistical reasons, but I hope to return to active radio soon.

why do i say we're onto a loss of memory efficiency by using a gc? because a 1.3x working set heap is probably quite tight and that's already wasting 30%, even assuming everything else is perfect. more realistic would be 1.5-2x for most apps i think.

of course we don't usually think about the bookkeeping overheads of malloc when we work with non-gc'd memory. they're not free. even assuming our malloc refuses allocations larger than 4gb (not entirely unreasonable tbqh), that's still a 32 bit size to store for it, even pretending we won't have other overheads (lol).

most modern allocators use size classes. we're disincentivised to use size classes for a gc because it means we're not filling blocks as often and we can't relocate different sizes into the same block to save space.

anyway i suspect that the memory overheads of allocators are not in practice wildly different from the memory overheads of GCs, albeit arranged somewhat differently.

It's kind of infuriating how, as soon as you try to do good, you're held to impossible standards.

People are shit and companies are shit all the time and nobody bats an eye. But do volunteer work for your FOSS community, start a project that tries to do things more ethically, just be visibly not shit, and people left and right come out of the woodwork to point out all the ways in which you are not being absolutely flawless and perfect, and all the work that needs doing that you're not yet taking upon you.

The people actually doing the work are also the people who are being asked to do even more, and who are being critised the most. It's a really insiduous pattern and we all need to be better at recognising it and squashing it.

littlegem: i have been thinking about heap layout with immix-style heaps. you know how most heaps put the header just before the value? turns out when you think about it, this is just a size optimisation that doesnt pessimise every allocation to the minimum size over putting them all in an array.

why? because if we're to avoid an inline header, we need a predictable place to find the metadata for a given pointer, which means one header per minimum object size, even though some objects might be larger than that. and turns out this gets quite large.

alternatives that still uses a predictable layout:

• fixed number of slots smaller than the worst case
• for each line, an index of the slot for the first object in the line. there are only 256 lines per 32kb block, so this is a much more manageable size)

this seems to have some difficulties associated, such as what to do when a block isn't full but has run out of object slots. perhaps we can make the block metadata external and put a pointer somewhere?

immix advertises "0.8% overhead" while having the audacity to talk about correct accounting and ignoring the size of the per-object headers entirely. this is not helpful for trying to work out what is a reasonable gc overhead actually. and since we're already on to a loss on memory efficiency by using a gc at all, it would be nice to bound it better

Hell yes. One, "don't engage, just block" is a great way for dealing with shitty people. It removes them from your sight, and you don't expend any further brain cycles on them, which is good for one's mental health. Two, there are lots of people for whom a single post is enough of them for blocking purposes. Three, there are literally hundreds of millions of Threads users still available to see after you block someone! You will not lack for people to see and read on the site! Block freely!
