all talks are recorded. so you can watch it live or on replay. Talks are free to attend; they are @ ULB campus in Brussels. 31st of jan - 1 of feb.

i remember reading about "lumina probiotic" Has anyone done research on it since, reviewing thier claims ?

their claims on their website:

replaces S. mutans, alters oral microbiome, reduces acid via ethanol metabolism, produces antibiotic, freshens breath, brightens teeth, lasts decades. etc

i am very skeptical of it

I recall they were offering a few people mail-in swabs to test if the colonization had taken hold, but haven’t read any follow-up.

Arch is nice if you want to tinker. Based on your reasoning, I wouldn't recommend it. But if you still want arch-based, I would recommend EndevourOS, and for even a simpler/better distro, Bazzite.

Split the difference, Fedora. its cutting edge but not in a way that can lead you to make mistakes like arch (BTW).

Its still open to customizing but out of the box is very damn usable and flexible.

Even better is Debian testing :-)

some people want machines that do everything but don't want to do everything to maintain them or even set them up

What are the use cases of CO2 appart for making my Coke fizz?

The main commercial use is enhanced oil recovery—shooting it into old wells to extract more oil (super ironic if captured from the air).

One application I think is neat is that it’s a pretty robust refrigerant in a heat pump application.

As I understand it, the main driver behind current carbon-capture tech is selling carbon credits.

You can add hydrogen and make methane for those industries that can't easily electrify

All the vaguely plausible industrial use cases for CO2 are a rounding error compared to the amount coming out of vent stacks and engine exhausts.

The one exception is making synthetic fuels, but in the vast majority of applications it’ll be cheaper to use electricity from clean sources (renewables/fission/fusion/unicorn farts) directly rather than pay all of the efficiency losses of electricity -> thermal -> chemical -> thermal -> (end use).

Ballpark, running a car on synfuels takes 10x the energy of running it on batteries charged directly from renewable sources.

On a much smaller scale I've been hoping for a small solar powered CO2 compressor to exist so I could use it for mosquito traps. The state of the art for those right now is burning propane for the CO2 combined with a scent emitter for the human smell to attract female mosquitos.

Synthetic food is a potentially big one.

Synthetic materials is another. For example carbon electrodes for batteries.

It is used as a shielding gas in some welding processes (notably, MIG welding.)

Off the top of my head, CO2 can be used as a solvent for dry cleaning, it can extract THC from cannabis, and can also be used as a refrigerant.

You can combine it with H2 to produce synthetic fuels. Not ideal but could reduce fossil fuel use and hence new CO2 released.

Third ingredient missed out: lots of energy.

The reaction of 3 H2 + CO2 -> CH3OH + H2O is exergonic, so the H2 already brings all the energy needed.

Dry ice blasting

You can think of industrial CO2 use as basically the same as nitrogen but a little worse and several fucktons cheaper.

CO2 is fairly inert. This makes it useful. Welding steel is a typical example of something you can use CO2 to shield. There are many other examples in the chemicals industries of things like that where you want to do something at a "higher than natural on earth" temperature to make a reaction happen or happen faster but you don't want that reaction to happen with oxygen all around.

And on the other end of the temperature spectrum....dry ice.

Plant food.

some leaked emails show they where quite close https://news.ycombinator.com/item?id=45043807

Peter Thiel was very close with Epstein : https://news.ycombinator.com/item?id=45043807

so it's unsurprising that the UK, which wants to befriend Pres Trump, would also like to befriend the VP (who owes his entire career to Thiel).

thiel and sacks have an old book where they try to make date rape (and intolerance for diversity) sound ok

Link?

This is shown in figure 5 of the paper. https://arxiv.org/pdf/2507.09089

There are many bugs/errors in the spec. LB is here to find most of them.

UPDATE

Update August 28: A day after publication, Apple informed us that the distribution rights (notarization) were revoked due to sanctions-related rules.

“Notarization for this app was removed in order to comply with government sanctions-related rules in various jurisdictions. We have communicated this to the developer,” Apple told us.

No further context was provided, but the developer purportedly had a Russian developer account, despite living in Malta.

Pitiful response with no specifics, as usual.

> The email's provenance isn't really clear, this could be a hoax.

i looked up the docs and it seems legit. the source is iran.
