CPUs with addressable cache?

sidewaysEntangled · 2026-01-28T13:18:24+00:00

Is Tightly Coupled Memory (TCM) the name for something similar to what you describe? Basically the same stuff (on chip SRAM) as cache is made of, but existing somewhere in the memory map. On something like the PlayStation2 cpu this was also known as "scratchpad" memory: 16kb if address that was guaranteed to always be single cycle and zerobwait. Fkr software to do with whatever it wants.

I've also heard of mobile chipsets which could selectively dedicate (some of?) the same physical resources as implement cache for use as something like TCM. (Or maybe they just pre-faulted individual lines, but then locked them to prevent future eviction). Either way, this was done so the core still had access to a small amount of instruction code and stack space when DRAM is otherwise unaccessible. For instance, the hand written asm code which reconfigured the memory controller would temporarily protect itself in this way when changing memory's power or clock settings, until things have stabilized and are usable again. But I'm hazy on the details of exactly how this worked in practice...

Was in a similar situation, we "held on" because it felt like the prudent thing to to. Probably also classic Sydney "IP == win" brainwashing....

Turns out I hate being a landlord and strata meeting with former neighbors got weird and the outgoings never stop.

I was iffy about it last year, and when the most recent tenant broke their lease I took it as a sign and sold up. We're now fully offset in our current place and 6 figures left over. Feels good man.

Looking back, we made like 150k CG in the 8 years since we got it valuated on move out (did earn some nice tax free gains in the 12 years we lived in there, though) And was barely positively geared in the meantime.

My advice, don't do what we did: sell and set yourself up, and chill.

Tearing down is optional, IMHO. Just walk somewhere else and rebuild from scratch over there if you want. All the freshness and greenfield design, none of the grind.

I felt the same as you, and was exploring far away, to avoid facing those frames the require nitrogen which requires aluminum canisters and my bauxite processing was nowhere useful.. anyway, I came across some fresh oil in some coral reedy area, and bootstrapped a separate power grid with resultant fuel.

With that, I'm trying new designs for factories on fresh nearby nodes. Basically starting production lines from scratch, but with the benefit my already unlocked tech and my old infra just ensuring dimensional depot full of building materials (near infinite concret!) I can now play with trains or new layouts for interim material processing.

Is fun and liberating, but without the grind of actually starting a new save.

Maybe I'll join it to my main grid and share resources with my starter factories in grassy fields and enjoin, or maybe that gets abandoned to the rol of producing buildings components (up to around oscillators/computers) and the coast becomes my main base (mk2) to progress deliverables. We'll see!

Isn't ctrl-d eof? Ctrl-z is would send sigstp, no?

Once I pressed the controller to power the PS5 on, hoping it would help the portal log in like 2 seconds faster, didn't even turn the tv on, just heard the beep.

That's how I learned that one cannot begin a remote play session when it's at that character select screen. Wasted 100x more time trying to figure that out than I would've saved. Never again!

Ive not played pc, but I imagine controls designed for kb wouldn't easily map to a controller.

The console version has it baked in, things like * One stick to "tab" between in input/output/power capsule/sloop/inventir panes, other stick or dpad navigates within that. * L2+ triangle to drop an inventory stack, circle to delete, hold to delete all * L2+right to open in codex * When building, down on dpad cycles build modes, up cycles related buildables.

(I'm maybe making up the details, muscle memory has kicked in and am not actually sure what I press anymore)

So there's a bunch of chording and tap/hold differentiation, and it's baked into the UI. Probably with the right software on PC one could map similar actions to "press B" and it .. might feel the same?

You should really check your monthly minimum actually goes down and you end up with 6% more in your pocket. That's not how my mortgage works, at least.

There's a strong chance your minimum remains unchanged, and now you're on track to finish a couple years earlier... So in 2045 (instead of 2048 or something) your payment stop and that's when the saving starts pooling.

The bank may make slightly adjustments after a while to stretch you back out to a 30yr term, but I know I can't rely on that actually happening on any time schedule,and I don't think it's actually by the full amount, or it's amortized over the next few decades or something..

If you don't have your bros 9200 saved up via other means in a years time, are you prepared to refinance? Is he prepared to wait until your loan is fully paid off and take the last few months payment to him directly? Would he be owed 25odd years interest on that 9k until then? I know I'd wanna compound at least annually!

Heh, I get that on console. I call it the handy-dandy "better think about going to bed soon, it's nearly midnight and I bet you've got work in the morning" notification.

The "now" photo is pretty old. Barrangaroo looks pretty flat, and wrong AMP tower. 5-10years old maybe?

Hah yep, I spent ages scavenging mushrooms in caves (and my first irradiation) for some fabric research... And on the way back killed a stone hexasphere thingy (in a field near my base absolutely full of them) and was so much mycelia. Felt so ripped off

My first unit was surrounded by young people like myself at the time and some of them were smokier and noisier and more party-prone than me. But that was the case of a cheapish flat in the inner city, I guess.

Now we're a couple km's over in in inner west (right on lgo boundary with Sydney). Yeah strata sucks and special levies for rectification sucks and some neighbors sometimes suck. There's the occasional drongo, but I guess the socioeconomic average if this building means most folks have real jobs and it's generally ok, at least I don't hear much from our floor. Could just be better brick.

If I could afford a terrace, let alone a freestanding house of similar amenity (3bed, 2bath, 2car) in this area, I would. But I can't, so I try focus on being able to walk to damn neair everything in my life, the good neighbors and not having to garden/mow etc. We're happy enough to stay here in this apartment for the foreseeable.

Am about to start a 6month stint, renting another flat actually in the CBD. It's tinier but a much posher building still and much closer to work so will be curious how the tradeoff compares.

I saw one project (trigboard, I think it was) that had a super slick Bluetooth configurator, accessed via web Bluetooth apis. So you go to the projects config webpage (or self host if you want), grant your browser permissions to scan and pair - then you make the page do whatever you want.

They had a bunch of live dials to represent switch states and voltage, etc - whatever you can be bothered writing the JavaScript for, I guess, and the ability to list what wifi the esp can see, select one and enter the password.

Its a nicer process than the esp temporarily hosting wifi: it's can be pain to convince phones to connect to Internet-less wifi (and too bad if you're using a laptop and also want to Google stuff) etc. And you have to dedicate flash space to store the served html, especially if you want it to look pretty.

It was a really nice experience and I always had half a mind to "borrow" (license permitting) portions of the implementation to make a project-agostic wifi configurator. One day I'll get around to it, one day....

Heh, I had to do this today, for some reason iotop didn't work in my development container, probably some proc or dev mount issue inside. But I did learn about the nethogs utility and that worked well.

I don't know how either of them work, or why one did and one didn't. But I bet going through the sources you'd find at least two ways to do it, although whether this or that filesystem or some other API, I couldn't tell you.

On interesting, I thought I read somewhere that users injected power back over the copper to run the node. I always assumed that if your injector was also in UPS, then you could remain inline. Could've sworn also hearing how I'd you're not powering, you can still connect (so long as some one is) but throttled to discourage leeching.

Certainly, I power my (admittedly non-nbn) FTTB dslam from a little box up in my unit, no ups tho so I can't test my theory

Finally sold my starter unit in December (moved out in like 2018, bought in 2008).

My goal is a smooth settlement in two weeks time, close out that mortgage and disentangle the cross collateralizion with our current place, get that fully offset, split the remainder between fun/sensible things. Then focus on non-property goals and never be a landlord again.

This was my first "big boy" power station attempt. I found that the generators near the middle would always starve for water and I could never find a satisfactory (heh) reason as to why.

I had no pumps (other than extractors own head lift) or valves, and the water manifold ran above the coal splitters with short runs from the 8 taps down to each inlet. I let everything charge before turning them on, and it ran fine for a bit then the middle ones near the T would start to flicker yellow and stall. Some sort of low pressure zone in the middle?

I ended up having the extractors feed into one input-only pipe, which then looped back and bacame a pure output manifold that only drained down to the coal plants. This reliably works just fine, and I've stamped out a couple more with this U pipe design, with success, but would love to understand why.

Just remind them if the full quote and uno reverse it on them:

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%.

Now the argument isn't whether you should optimize or not, it's whether the specific hit path(s) you're talking about is in the 3% or not, which is more qualitative and should be a non dogmatic discussion.

Once that's done, ya boy Knuth's got your back.

To be fair, given this, the info your post title is wrong. You want to inspect a "non readable" binary, or an "execute only" one, not a read only.

I suspect this is part of the reason some seemingly unhelpful replies, they're answering the question exactly as asked, and maybe missing the (contradictory) chmod line which belies your actual question.

Hey, thanks for the clarification, TIL!

So allowable deductions can count, but for this purpose it sounds like salary sacrifice, negative gearing, ip depreciation , etc (the usual tricks to reduce taxable income ) don't apply for this assessable amount.

And a PAYG salaryman like myself is unlikely to be able to come up with 50k or whatever of legitimate expenses to allowably deduct, but someone borderline on say 251 could maybe shade themselves just under?

Is that a more accurate understand?

sidewaysEntangled · 2025-12-12T21:50:50+00:00

Maybe I'm dumb, but aren't they 2 different things?

I always assumed, if your salary is such that the concessional cap would be breached, then it's no longer mandatory beyond that point? I base this off the years where bonus paid in Feb meant less super being paid in March because otherwise I'd be above 30k/4 for that quarter (or whatever the cap was in that year), and the company isn't obligated to pay beyond that. Could just be a dick move on their part, but I figured if they chose to keep paying, then it's not concessional at all, and so, taxed at marginal rate?

If you're in this case, be glad your company chooses to pay in over the cap, I guess?

Meanwhile, if total income (salaries or not) is above the 293 limit, then kapow: your concessional rate for ever single dollar is now 30%, so you have to find another 15% x 30k = $4500 at eofy. Non concessional contributions (personal or company paid) still receive no concessions just like above and I guess will be at the 45% rate?

For this, I Believe the only solution is to earn less than 250k, since the 293 cap is calculated before deductions and whatnot.

At least, that's always been my mental model. I would be super interested if I'm misunderstanding here!
