> Porsche’s eFuels are made out of CO2 and hydrogen and are produced using renewable energy.

Am I missing something obvious? Even if the fuel production is carbon-neutral, wouldn’t the ICE cars still be combusting the fuel and releasing CO2? Hydrogen fuel-cell cars don’t release the CO2 because they use a different reaction. What I don’t understand is how this new fuel would change the fundamentals of an internal combustion engine regardless of how it’s made.
they are often actual cia agents, which means collecting humint and building sources and networks. eg

Please see my sibling response -- Postgres doesn't do async nor direct IO, default is fdatasync() now on linux and before it was fsync().

Here's a breakdown of the write path that is mostly correct which I typed out on reddit[0]:

- (Postgres) transaction occurs, generating WAL records (write()s are issued)

- (ZFS) receives filesystem writes makes transaction(s) and puts them in the current transaction group ("txg"), in memory

- Exception: assuming logbias=latency if size is bigger than zfs_immediate_write_sz then the write goes straight to disk and a pointer is written into the ZIL instead... Bit blurry on this

- (Postgres) wal_write_delay time passes (default 200ms) or enough wal_writer_flush_after (default 1MB) data is added

- (Postgres) initiates WAL flush to disk -- i.e. calling fsync()

- (ZFS) sees the fsync(), and this means it must do a file-specific ZIL flush
- it is possible for the txg to be committed first which will also trigger a ZIL flush

- (ZFS) performs a ZIL flush, writing ZIL records from memory to disk

- (ZFS) zfs_txg_timeout seconds passes and a "SPA sync" is performed

- (ZFS) transactions in the current transaction group are processed (+/- compression, encryption, etc) and are written to disk

- This does NOT concern the ZIL records, these are writes in the transaction group that have not already been committed

- [CORRECTION] direct sync records written as ZIL blocks are also added to the current TxG in memory. They are processed identically to async writes come TxG commit time and aggregate with them (they are async writes once durability is assured with a ZIL write). (see this comment by /u/taratarabobara)

All that said I haven't read/written enough of either codebase (ZFS/Postgres) to consider myself an expert, so there may be logic bugs in there!

Interesting, no wonder AWS head became Amazon CEO.

Their retail/e-commerce side is less profitable than AWS but the absolute revenue is still massive and the risk of losing that a chunk of that revenue(and income) due to tech issues is still enormous risk for Amazon .
Open source doesn't really work like that, there is no top-down decision maker setting priorities for what should be done in any given distribution. Usually what happens is you wait until it becomes enough of a problem that some distribution fixes it, but this one is low priority given that distributions would probably prefer to focus on native Wayland ports for the software they have control over that is packaged in their distribution. And for the external software they don't have control over, it's much harder to find people to work on those.

Early data may be less biased than later data. The data should just be released anyways since the damage has already been done.
A reminder that naivete is valuable. Without it, nothing would ever change.
if you have m-bit numbers you can simply loop all of them and find which one when squared is closest to 2. This alogrithm will run in O(1).

Alternatively you can do the same thing with drawing a square and measuring the distance between the center and the corner. Perhaps it's a little cheaty since you have to include a precomputed sprt(2) for the diagonal length of a pixel.

Yes, but you are correct in another way.

If the US diplomats Uganda used the NSO technology to spy on are intelligence agents, they still possess diplomatic immunity. They are in Uganda with cover (as opposed to non-cover; that is, they are in country without being a public US goernment employee).
Today across a range of digital media referring to different peer review input sources (imperial college in England, somewhere in Scotland, and now this one from South Africa) I've read 40%, 60% and now 80% - I think we can agree the number is still being refined, and probably reflects a range of pre vaccination, exposure, co-morbidity and societal differences
Electric cars are currently mostly charged at night (since that's when electricity is cheaper), but as solar becomes more prevalent, that will swap. Charging cars during the day is pretty easy, just require office parking lots to have chargers (and possibly subsidize).

You are right that you can't have an electric wire across the Pacific to get power from the US to the EU, but more because the EU doesn't border the Pacific. On a more serious note, Novia Scotia to Ireland is about 2600 miles, so it's on the edge of doable with HVDC, but it would be a massive project and slightly hard to justify.

I'm interested to know what rare earth metals make up so much of a wind turbine. According to https://www.nrel.gov/docs/fy17osti/66861.pdf (page 65), around 99% of a turbine is accounted for by steel, fiberglass, iron, copper, and aluminum.

What will be interesting is to see the long term mortality rate. My hypothesis is we’re just accelerating the deaths of people over 70 years old (70%+ of the cases).

If that’s true, you’d see a decrease in mortality over the next few years. Covid is basically doing what the flu does every winter (but on a larger scale) - it pushes people close to death over the edge.

> "Just get rid of the large ornament and generally useless front lawn."

walking (my dog) around my neighborhood, which has a surprising number of different setback standards, has led me to think about this issue abnormally often. some blocks designate as much as ~40 ft of setback, requiring large front lawns, while others have ~10 ft, with just a strip of greenway as a buffer between the street and building.

observing that, i've settled on 12-15 ft setbacks being an ideal transition from public to private space in our urban landscapes: 4-5 ft of parkway, 4-5 ft of sidewalk, and 4-5 ft of vegetation to the building envelope. this provides plenty of greenspace and the requisite public walkway right through that greenery, while also maximizing the space left for housing. for unusually space-constrained blocks, you could remove the parkway, put the sidewalk right on the curb and get this down to 8-10 ft of setback.

on top of this i'd convert all on-street parking to protected micromobility lanes and narrow neighborhood car lanes to 9 ft max. this would minimize the amount of urban space dedicated to cars, while still providing car access, and also allowing a diversity of mobility options.

the last but most difficult change i'd suggest is requiring all car parking be underground, accessible via a single underground alley down the lengthwise spine of each block (houses with basements could have entries directly from the underground garage to the basement, for instance). this drastically reduces driveway cutouts and cross-modal intersections, thereby reducing cross-modal collisions, injuries and deaths, while also minimizing the surface area dedicated to driveways and parking.

For loans over a certain size (definitely anything mortgage size) there is no limit on the length of the credit report given to them. They may not care when it's been so long, but they can see it all.
You're right! This article actually wasn't meant to be a benchmarking-style post, I didn't actually share my notes and numbers, because I originally started just experimenting and kind of fell down the rabbit hole. This originally started as me trying to pick a local filesystem after moving off of Ceph-for-everything -- it started as an mdraid vs LVM vs ZFS experiment.

That said, the reasons I haven't published all my notes is because:

- I only used one testing software pgbench (which is notorious for producing)

- Good evaluation needs a long term assessment of drive fragmentation which is hard to do (and literally takes time)

- Sometimes I changed multiple variables at a time, and not all the values I have in my notes are averaged across multiple runs, etc.

So in the end this post was just gathering what other much smarter people have said that I took inspiration from so it's all in one place.

Some intuition as well on why 16k can work better than 8k is in that scale15x talk -- for sequential table scans, it's almost like you're pre-faulting. A contact I've made through this research also recently suggested to me that I was only scratching the surface -- bigger record sizes should be better, as long as write amplification can be managed and fragmentation avoided (via a SLOG or more tuning).

This was clearly the plan all along. Such companies live and die by their low profiles. Was probably not the founders' first such company nor will it be their last.

Next step will be to close up, take the contacts, clients, capital, the lessons learned and the cream of the staff to whatever mercenary, unethical piece of crap they make next.

This is why killing the industry as a whole is so important. It'll mean going after the owners, suppliers and employees/contractors with naming/shaming, coordinated sanctions, criminal charges, designated persons lists etc. until their reputations are trash.

Its not the first time they’ve been vague about this.

Their wording actually in other cases makes it seem like they have already derived the private keys and move to seize it once establishing any US nexus. They’ll say things like “we noticed we had that private key” and ask a judge for forfeiture, which is surprisingly professional restraint but curious.

Should be investigated further.

People should use multisig in something brazen and see if it still happens. Taproot helps make multisig use indistinguishable from non-multisig.

> Yo, just because a new student getting loans right now can get 4% doesn't mean that 7% wasn't absolutely the norm for many people over the past decades

Subsidized loans were at 6.80% for the first two years they used fixed interest (the academic years 2006-2007 and 2007-2008); this is the highest they have ever been under the fixed interest regime; there are three additional years they were at 5% or higher.

Under the variable interest regime before that, they spent some time at 7% or above in the 1990s, but those would have fallen with general interest rates.

I feel like on dates, light touching should be an expected possibility. Trying to hold a hand, put an arm around one another, etc.

If it isn't wanted, simply decline it.

The idea that no physical touching can be initiated in any manner before asking on a date is a bad thing.

Sure, but what’s the original sin at work here? Google investing their time and resources into their browser projects, or the fact that web became this complex mess because web developers beat the drum for 15 going on 20 years that the web should be an app runtime?

Duplicating an app runtime feature for feature and bug for bug is difficult in a capital intensive sort of way. Even companies that can afford the expenditure, primarily Microsoft, decided to get out of that game because that level of expenditure comes with its own opportunity costs even at their level.

And there are alternatives: WebKit and Mozilla, one of those is the exclusive web renderer for iPhones and iPads which is not an insignificant amount of hardware in the world.

Google puts the work in. It’s really just that, and it’s their private prerogative to put that work in if they so choose, where others choose not to. The diversity of rendering engines isn’t great compared to say 15 years ago, but it’s not so bad that it’s a total monoculture in the way IE6 was. Actually thinking about it, more people are using more and different browser rendering engines than back then because Chromium-based browsers don’t have the total dominance that IE6 did, and there’s a lot more people on the web than there used to be. We had diversity, but we’re talking iCab, pre-WebKit OmniWeb, Opera on Presto, and yeah, Trident’s not really around anymore, but it was there, and so was Gecko and WebKit.

At least you don’t need a browser that supports ActiveX controls for regular websites anymore.
Nothing in the article you linked to supports your claim that "Cloud is not really such a problematic factor". In fact, the article explicitly states:

> However, clouds can block light from the sun. So, do clouds affect the creation of energy by solar panels? Yes, but it depends on the types of clouds and where those clouds are in the atmosphere.

> When sunlight hits low clouds, a lot of that light – and heat – is reflected back into space. […] So, if you live in a place that commonly has a lot of low clouds, solar panels might not be able to produce as much energy as they would somewhere else.

——

> And the nice thing about nights is that they are quite predictable. So not a very difficult problem to solve.

Non-sequitur. The fact that it's predictable doesn't mean it's not a difficult problem.
The desire and pressure to consume conspicuously is something embedded in US culture, much like smoking was. Make it rain. Just don't tell me what my APR is in the morning.

The amount of discipline required to save and defer gratification is enormous, and it is a continuous effort, particularly in this country. You are one of the few. One of the brave. Congratulations!
You're right. That's been my argument against trusting "the cloud" (i.e. somebody else who actually own the computers on which you place all your precious trade secrets and personal business) for the past 15 years...ESPECIALLY when there is no clear agreement or customer/vendor relationship, and they're doing it for "free".
Okay, I've accidentally put a pointer type into an interface, now what? How do I check that the inner value is nil/not nil? Mmmmm?

It's a defect in the language, plain and simple: if a pointer-to-type implements interface, then converting a nil pointer to type to the interface should result in a nil interface value (that would compare equal to nil) instead of a non-nil interface value that has nil value pointer inside it — which is a second kind of nil in anything but name. You compare it to nil, it says "not nil", then you try to use it and it blows up with panic "I am actually a nil, gotcha sucker".

Hospitals are packed... idk what you are talking about.
This comment isn't really correct all, it's not possible to do that with the architecture of X. The best you can get is XSecurity and its related extensions, anything more than that is going to break the protocol. There is quite a good reason that Qubes has not even tried to get X to do this. The main issues are that the protocol is sequential and you can't reorder requests which makes modern polkit-style mechanisms practically infeasible, and also you can't really fail anything because errors are usually treated as fatal in Xlib and most clients don't bother with error handling in Xlib because it is complicated and badly implemented. More about that here: https://news.ycombinator.com/item?id=21267275

BTW none of the issues occur in D-Bus, that was designed to fit these use cases which is why it typically gets used for "privileged" APIs on Linux. Fixing this issue in X11 would probably entail throwing out the protocol entirely and making something new that works more like D-Bus. Maybe you could avoid that by hacking Xlib and making another X server with an elaborate set of heuristics but that won't work for everything and also seems like a really bad way to do security. At best you probably rewrite the whole X server to end up with something roughly equivalent to XWayland.
Both are plausible avenues, sure.

Ultimately, the point is “once law enforcement has you and your devices in their hands, it’s probably all over”.

I'm surprised to learn the third myth is even a myth. My thoughts and feelings change significantly when I switch from sitting to walking/running or move from an indoor room to sitting outside in the sun. When I go from being in shape to out of shape my brain feels much more lethargic. I could go on but the general point is that changes in my physical condition have a big impact on my mental processes and vice versa.

I had thought these responses were normal and the body and brain are deeply linked to each other. Do most people not feel these same effects?

from the UK - groundsource vs air-source heat pumps makes a huge difference. Last i checked:

- ground source was roughly parity with gas (with something like an 8x higher install cost)

- air source heat pumps were more expensive to operate but similar on install costs

However comparing on cost only misses the point, a heat pump is generally capable of cooling as well, which is becoming more of a necessity in the summer.

P.S. You can do silly things with ground loops like use excess solar power to cool during the summer or daytime storing that heat in the ground, then removing some of it in the winter/nighttime.

> There's no "w" sound in that video for the number 5.

Yes there is. You can argue it's not as strong as an English 'w', but it's there.

> This is a really common misconception/mispronunciation caused by pinyin as it needs the "w" for disambiguation purposes (see also the use of apostrophes, xian vs. xi'an).

That may have been the case in the past, but the 'w' is definitely pronounced now, just like all the other 'w' sounds in Pinyin.
