According to the writeup; there are two methods: it is possible for an extension to mark some parts of itself as 'web accessible'; and linkedin has assembled at least one characteristic file for 6,1000-odd extension IDs and attempts to fetch it to confirm/deny the extension's presence.

The other is based on the fact that the whole point of many extensions is to modify the site in some way; but the site normally has largely unfettered access to inspect itself, so they have theirs set up to walk the entire DOM looking for any references to "chrome-extension://" and snagging the IDs if found.

Not exactly a 'declare installed extensions'; but it looks like, out of some combination of supporting the use cases where an extension and page actively interact by design and either not wanting the possibility or not wanting the complexity of trying to enable 'invisible' edits(presumably some sort of 'shadow' DOM mechanism where as far as the site and everything delivered with it knows only its unedited DOM and resources exist; but the one the user sees is an extension-modified copy of that one, which sounds like it could get messy), inferential attacks are fairly easy and powerful.

Artemis II is breaking Apollo 13's record by about 4100 miles. The primary reason they're going further is because they're passing much farther from the moon, about 4000 miles, compared to 158 miles for Apollo 13. The moon is also a little further from Earth, accounting for the other 250 miles.

Agreed. I live in the mountain west, and our forest and mountain landscapes are just covered with fencing, even though most of it is public land, because it's BLM "multi-use" land -- a lot of cattle graze on it. Fences are expensive to build and expensive to maintain. If you think a fence is something you build once and then ignore, you've never dealt with cattle.

Cowboys (and sheep herders) have a term "ride fence" as in "Bob, you're gonna ride fence today", and it's a regular and tedious task that means "get on your horse (or ATV) and ride past miles and miles of fenceline, looking for places where the fence is broken or going to break, and fixing them". It's necessary and expensive drudgery and having all of those fencelines is bad for other uses, and bad for wildlife. I've put down a few deer that jumped a barbed wire fence and didn't quite clear it, slicing their guts open and leaving them in agony as they slowly die.

In addition, there's an obvious tension between the cost of building and maintaining fences and the cost of rounding up cattle when it's time to move them. Obviously if you slice the land up into lots of small fenced areas, the cattle will be easy to find -- but they're also going to graze it out fast, so you're going to have to move them more often. If you use very large enclosures (common on BLM land), then your cows may have hundreds of square miles to roam and feed... but when it's time to move them you have to find them. Luckily they're herd animals so when you find a few you've found them all, but still. And occasionally, singles get separated from the herd and you just lose them, which isn't great since a cow is worth about $2k.

So... if we can replace those miles of expensive and constantly-breaking fences with virtual fences, that's good news for everyone. Wildlife and outdoorsmen can roam unimpeded, cattle can be far more tightly controlled, strays quickly identified, located and reunited with the herd -- via remote control!. This is an innovative idea that is worth quite a lot.

Where exactly does supporting 3 people on $133k/year count as 'upper middle class'? You could be doing a lot worse, and many are; but that's not just tons of money in a HCOL area; and that's also lower than twice the median salary for full time employees with bachelor's degrees; so you are calling either a single income household doing a bit better than median or a dual income one doing worse 'upper middle class'; which seems pretty ambitious.

It's hard to train a cow to keep its cellphone charged; so you can see why you need something to keep their tracking collars topped up.

Realistically, the status quo has arguably outrun the dystopia there. Your phone already does far more than anything you could get into the power envelope of a bracelet or embedded chip implant, and if for some reason you've raised enough eyebrows that you'd be hauled in for an RFID read DNA is a pretty indelible identifier.

It's not 100% ironclad; but penetration is broad enough that you've basically got the majority carrying highly fingerprintable RF beacons and the minority standing out for their relative radio silence and attempts to deal in cash. Expensive and uncomfortable ankle trackers are good business and feel nice and punitive, just to remind the wrong sort of people we aren't happy with them; but you don't really need to impose a surveillance society when it will build itself for you.

My (admittedly anecdotal from the totally unscientific sample of random stuff I've had reason to work on) impression is that some 'shared' BMC ports had oddities related to network controller sideband interface speeds, since NC-SI is what the BMC is depending on if the NIC is on someone else's PCIe root. It's not like the BMC actually needs a faster link for much(normal management traffic probably doesn't fill 10mb and mounting virtual media may be literally once-in-a-lifetime) so the actual speed of the NC-SI interface was not a burning priority; but it left things up to the NIC whether it would support remaining at gigabit speeds and just quietly slipping the trickle of shared traffic in(presumably slightly more complex; but seems to be what the newer ones do) or if it would knock the link rate down visibly to simplify the case.

You see little echoes of similar behavior elsewhere. The intel desktop and laptop NICs that support 'vPRO' will be GB or 2.5GB when the system is on; but quietly drop back to 10 or 10/100 when it is off and it's just the management engine listening. Some enterprise vendor USB docks do similar things; looks like a normal USB NIC when the OS is up; but drops to a lower speed and operates quietly over, I think, some sort of oddball vendor-defined messages if one of their systems is plugged in but off.

Does it actually bog down a reasonably-speced computer? I don't think it does, I think the sluggishness is just from the sheer volume of stuff that has to be downloaded, and the inefficient way it's downloaded. And the reason the web devs don't notice the awfulness is (a) their browsers have 98% of it cached and (b) they have a GigE (or 10 GigE) connection to the server. They certainly don't have computers faster than your M4.

I think you didn't understand what this feature is. It's pretty much the opposite of annoying, and it has no effect at all on bandwidth consumption. Though I suppose when devs get used to their sites seeming to load faster they'll bloat them up even more...

I assume that, as an exercise, getting 5 simultaneous introductions working makes for a better paper; but is there a reason why you would want that in practice? Especially if there is any wobble in the ratios either randomly, across generations, or in the presence of certain environmental conditions that tweak the plant's metabolism one way or another that sounds like it would be a real pain in the ass to have to re-balance (and, if different patients are deemed to need different combinations even a perfectly stable plant is going to need re-balancing of the outputs) vs. very specifically going for a specific target output per-plant(or e. coli or yeast or whatever is easiest to bioreactor) and then just mixing to taste after purification. Is there some advantage I'm not seeing?

I realize that there are cases where some plant-sourced pharmacological effect looks like it is actually driven not by the identified 'active ingredient'; but by dozens or hundreds of assorted things, and in that case you just have to live with the complexity if you get better results with that than with purified isolates; but if you are deliberately engineering for very specific outputs why a mix of 5?

To what are you alluding?

Basically everyone who lives in the area or studies the climate or hydrology would tell you that you're insane.

More like a once-in-a-millennium event. Though I suspect it's going to be considerably more common going forward.

Deserts have some amount of normal precipitation, too. And when you get a lot less than normal, that's called a drought. Yes, even in a desert.

We do have pretty good data from tree rings. Unless you think the trees came from somewhere else?

Even worse is when they compromise the VPN operators and then monitor your usage until you do something that makes them decide to crack down on you.

People erroneously think of VPNs as privacy protectors. They aren't, not unless you have very good reason to trust whoever is running the server. If you don't, then they're concentrators for likely subversive traffic and its origins.
