Whoever wrote that rule was probably long gone, and in their defence, they probably weren't expecting one of the authors of C to turn up.
The real idiot was whoever his boss was, who didn't just tick the "passed the C test, ok to commit code" box, manually.
As they're going to be on the side that Pink Floyd was singing about
Sorry to ruin the poetry, but the far side of the Moon isn't actually always dark, it's just always turned away from the Earth*. Also they're not planning to land there, but instead at the Moon's south pole, where there's some areas in permanent darkness (about twenty five Kelvin), and others in permanent sunlight (about four hundred Kelvin), so the suits are going to have to potentially deal with the whole range of temperatures.
* Although, when the near side of the moon is not being lit by the sun, it does still get some illumination from the light reflecting off the Earth. So it would be fair to call the far side of the Moon the "darker side" of the Moon. Which sounds like the title of a remix album now I think about it.
Back in the day, when the best upload speed you could expect from ADSL was about 256k, my boss decided to get an SDSL line (Symmetric, rather than Asymmetric), which was a blistering 2MB both ways. (Better solutions were at least 100 times more expensive, and out of our budget).
This worked pretty well for a while (paired with an ADSL line to cover staff web browsing), until one day it stopped working for no obvious reason.
After a lot of back and forth, it turned out that we were one of only three other customers in the South West using SDSL. Consequently, most of Open Reach's staff had never seen such a thing, and so one soul, seeing what looked to them like an incorrectly wired ADSL line, took it upon themselves to 'fix' it.
IIRC it took a couple of days for them to find someone who knew how to wire it back up.
I remember seeing a friend's PC, that he refused to upgrade to XP SP2*, which kept getting spammed with messages from the internet. He was very thankful when I showed him how to disable the service and stop them. I have no idea how he put up with them for so long.
*(he was already running XP, he just didn't want to install the service pack because he's a stubborn sod)
I guess that's why elReg linked to their own article on that story. Along with a couple of other articles on the exact same idea.
Or did you skip over the sentence reading: "In fact, the concept of heating buildings and homes using servers is something we've all heard before, again and again."?
In terms of orbital mechanics it's actually easier to raise an orbit, than lower it (because you're getting further away from the Earth and the effects of it's gravity lessen). The big difference though is that as you reduce your altitude you get more and more drag from the atmosphere which does the work of slowing you down for free.
So to put the ISS (say) 100km further up would take a lot of energy, but to bring it down 100km to the ground, you only really have to get it into the thick part of the atmosphere.
Of course, then you have to work out where it's going to land. Predicting where a uniform shape like an Apollo or Soyuz capsule will land is tricky but possible (within a few miles). Predicting where a big complex shape like the ISS will land is much more difficult. Even aiming for something as big as the Pacific ocean is tricky.
Falcon Heavy hasn't launched any Lunar-bound payloads (yet). Falcon 9 did launch the 'Transiting Exoplanet Survey Satellite' on a Lunar flyby, although I suppose it doesn't count, because it was only really using it for a gravity assist. And of course, Firefly's first mission is currently scheduled to fly to the moon on an F9.
The obvious rocket that's been missed out though is RocketLab's Electron, which has already launched a (fairly small) payload to Lunar orbit (CAPSTONE).
I recall us getting a 512k expansion for our A500 within a few months of getting it (I could be wrong). I also remember that the one my dad got didn't fit unless you left the trapdoor off, so we just sellotaped some paper over the hole to keep the dust out.
Oh, and it had a real time clock unit too!
They didn't forget how to build the RS-25 engines, they only shut down production in 2007/8. Instead they're building a new, cheaper*, non-reusable version (RS-25E).
* They claim it will be cheaper, but I'm sure this is a cost-plus contract so we can guess how that will turn out.
A couple of friends of mine came back from the pub, stuck a pizza in the oven, then sat down on the sofa to wait for it and fell asleep.
They were shaken awake by a fireman, who had been called by a neighbour who had seen the smoke, and they'd arrived to find the front door wide open. They'd walked in, turned off the oven, put the fire out and somehow* my friends hadn't ever woken up.
* spoiler, it was the booze.
Don't feel like you have to wait and then switch over. Try installing Mint (or any other linux) on a spare computer, or in a VM. There's a good chance it won't do everything you want, but you'll pick up a bit of knowledge, and it's just a spare computer so it doesn't matter if you just wipe it off afterwards. Then next time you try you'll have a little bit more starting knowledge, and can get just that little bit further.
I still don't run linux as my main desktop, and I don't think I ever will, but I do now 'have' to have a linux VM constantly accessible, just so I have an outlet when I need to do linux-y stuff.
Even once the checksums of the vulnerable binaries have been added to the revocation list, that list still needs to be imported into the UEFI of each device.
Presumably Microsoft could make sure that the dbx update wasn't applied until after the bootloader had been updated in the same way that fwupdmgr
on Linux checks before it applies a dbx update that it's not using binaries that are about to be blocked.
I guess you could run into a problem if you update your 'BIOS'* and that updates the revocation list, before you've upgraded your OS
* Technically it's a UEFI not a BIOS any more, but I keep using the old name
Linux already had this problem a few years back, when a vulnerability was discovered in grub
(CVE-2020-10713).
In that case, the vulnerability was fixed by August 2020, but the UEFI revocation list wasn't updated until at least October that year. Unless you've used fwupdmgr
to update your UEFI since then, your system will still be vulnerable to an attack leveraging the old version of grub
. (As well as this new malware I guess).
That's not how relativity works.
Lets pretend that there is a massive difference between the passage of time on the Earth and the Moon, such that humans could actually perceive it. Next, we make a one metre-long stick, by carefully measuring how far light travels in ~3.3ns, on both the Earth and the Moon.
If you used a telescope to look from the Earth to the Moon the Lunar metre would appear to be too short. Conversely, someone on the moon would perceive the Earth's meter as being too long. (Unless I've got that the wrong way around).
However, if you took both metre sticks up into orbit and put them next to each other, they would be exactly the same length.
The SI units don't change. Our measurements of things might change, if we're in a different reference frame from the thing we're measuring.
In reality, generally the differences are too small for humans to have to bother about them much, fortunately.
Ok, now that is news. Do tell, who is this manufacturer?
I mean, you could imagine that maybe some of the high end brands selling luxury cars have to take care of their customers, but from what I've heard they're even worse than the 'normal' manufactures. Ferrari, for example, treat their customers like absolute mugs.
My mum has no interest in technology, but one thing she does care about is image quality. Consequently, we always had a Trinitron.
The first one lasted at least twenty years, before a dodgy power switch retired it to Amiga monitor duty, and it was replaced by another one in the 90's and finally a widescreen Trinitron in the 2000's. These days they have a horrid Samsung flatscreen that everyone in the family loathes.
More likely they don't have a new Soyuz ready for the next crew, until near September (because they're effectively down one craft now).
So the current crew get an extension, otherwise there'd be a gap with no Soyuzs docked to the ISS, and that would be embarrassing for Roscosmos. (Although the US was in a similar situation for several years after the Shuttle stopped flying, and they got over it.)
Of course, her policies were mischaracterised by the "left-wing economic establishment". Every economist who ridiculed her plans is clearly a communist, and the cataclysmic fall in the GBP was clearly a perfidious foreign plot. If only more people would read Ayn Rand, they'd understand!
So if I split the cost of something with a friend, and they transferred the money to me, it would be taxed at 0.01%
Or if I was getting a refund for something?
Wouldn't this hit people on weekly incomes, (who are typically earning less), harder than those who are paid monthly?
If you're going to invent a fantasy tax in future, try and concentrate on it hitting the rich harder than the poor.
I'd take issue with:
The goal of this content is always to promote a particular product/service/thing
That's just an advert. Quite a lot (most?) 'content creators' aren't making adverts, they're making entertainment of some form or another, and then being paid by Youtube (or wherever) a proportion of the revenue for the adverts that the hosting site has shown to viewers. Some income also comes from subscribers.
Often they will also make adverts for specific products, but on most platforms it has to be clearly marked as 'sponsored'.
At the more professional end it's pretty much the same as a production company filming a TV show, and selling it to a channel. Indeed some 'content creators' have shifted to making TV/streaming shows.
I suppose the only gas stored in my house is what's currently in the pipes, but rather than a tank full of a set amount of gas, it's connected to the gas main, which will keep pumping flammable gas in.
I'm not sure that's any safer.
(Not that it's particularly unsafe, but then nor is most gas storage, as long as it's built well and is well maintained).
