The lasers alone set you back many tens of k so it's not really possible to do on the cheap presently, even if a lot of the cost is expertise and the high overhead of R&D costs when only producing small number of units.
Oh and to know if it's any good you have to either build two (ideally more) of them to compare against each other (ideally using different approaches so their errors are less correlated), or have access to a clock better than the one you're building to compare to. So you can rarely get away with building just one if you want to know if you've succeeded.
The Carnot limit is the theoretical upper limit of the efficiency of a heat pump, so the stated number is presumably with respect to that, not heat moved per unit energy input like you're quoting.
Melbourne property prices actually haven't recovered from their 2022 peak, and that's before adjusting for inflation. I believe rents are down in real terms as well.
Things have been crazy for a long time, but I am actually optimistic for Melbourne specifically - the construction rate is up and the state government has been decreasing the power local governments have to block or delay development. If this continues, housing affordability should improve. My main concern is that a change of government may put an end to it, but I hope not.
Some details about what VIC is doing differently in this AFR article if you're interested (archive link because original is paywalled):
Population growth rate in Victoria has been 1.9% YOY average for 20 years, with no sign of slowing down. Even if they hit their targets, demand will exceed supply.
The Victorian government has also failed significantly on public housing. The wait time is about 20 months (10 months is VicGov's target, it was 14 months 3 years ago) and they're currently looking to demolish many existing options without many short term optionsnfor residents.
It seems very unlikely to me that Victoria's house prices will drop in any sigificant way this decade.
I don't think there'll be any significant drop on a sub-decade timescale unless there's some kind of financial crisis, but the ideal kind of trend is prices stagnating or growing slower than wages, which is the case right now - and the question is whether it will continue.
I think there is a good chance it will, as long as a change of government doesn't deliberately dismantle the current approach. Yes there's population growth and yet prices have been stagnant or declining the past few years and construction has picked up. That's a good trend!
I'm not familiar with the situation with public housing but am happy to accept if the government has failed there. But this seems like a separate failure rather than an indictment of their approach to increasing supply generally which I think is working.
Parent mentioned specifically finding them from the index, so they've been added but not committed, so they're not even remote nor have an author associated with it, yet.
And why it matters to get them from the diff if they're on disk already? Literally one command to find all of them, rather than going through git?
One advantage of git is it shows you any uncommitted changes. Great way to get context the next day of where you were up to anyway even if you didn't use TODO to make it searchable.
Mercurial on windows was "download tortoisehg, use it", whereas git didn't have a good GUI and was full of footguns about line endings and case-insensitivity of branch names and the like.
Nowadays I use sublime merge on Windows and Linux alike and it's fine. Which solves the GUI issue, though the line ending issue is the same as it's always been (it's fine if you remember to just set it to "don't change line endings" globally but you have to remember to do that), and I'm not sure about case insensitivity of branch names.
Pretty sure Mercurial handles arbitrary filenames as UTF-8 encoded bytestrings, whether there was a problem with this in the past I can't recall, but would be very surprised if there was now.
Edit: does seem there at least used to be issues around this:
When evaluating successors to CVS back in 2007, Mozilla chose Mercurial because it had better Windows support than git. 18 years later, Mozilla is now migrating from Mercurial to git.
I migrated from Hg to Git a few years back, only because BitBucket forced my hand and most of the hosted CI tools stared dropping support for Mercurial.
But I still prefer Hg over Git.
He tried an experimental payload that contained two ADCs, one BRAF inhibitor and something else, maybe PD-1 inhibitor. Then he had surgery. Payload-heavy ADCs are the way forward against difficult cancers.
They're using weakened viruses. Virus use in cancer is nothing new, but an interesting field. I can see why pharma hesitates using it, viruses can mutate, too, similar to cancer.
