I started to write a stupid comment about how insanely fast the focus on the EOS R5 C is- only to remember it’s a non reflex !
The difference in focal time between my 5D mkii even with the best lenses, and the R5 C with a cine servo or vcm is insane. The R5 feels instant and only ever searches if it’s been locked to an inappropriate point.
I’ve self hosted a server for various things going back to somewhere around 2006/7? Whenever I finally had access to a non dial up connection.
I’ve not always used it for anything amazing, over the years it’s been just an ftp server, just http, just a Remote Desktop, a Minecraft server, email server, etc etc. (obviously sometimes combinations, and the hardware has changed from the original - the original being a motherboard without an enclosure I would start by shorting the pins with a butter knife ….)
Not the person you’re replying to but backing up what you’re saying - I read a lot of fiction for pleasure, I can say with some assurance whether I’ve read a certain fiction book, or, any book I’ve read for pure pleasure.
(Though as time goes on and I get older… I once started reading a book and about 15 pages in realized I had read it before )
As a hobby, I do a lot of wood working. Recently I was acquiring some books on wood finishes. I accidentally bought one book three times - not all at once but over a several year period. I realized this while trying to organize.
Mainly because they can have very similar / generic titles, and be by different authors. Since I’m using them as a reference, even if I know the author, I can’t always remember if I own this book by them or maybe I own this book with very similar title by a different author.
Oh yeah I can definitely remember all the books I've read. The only ones I've ever bought twice were ones I hadn't yet read but had sitting on my shelf for a while with the intention of reading sometime.
> Please always use a good quality loudspeaker connection cable from an audio dealer. To prevent impairment of sound quality, we recommend cables with cross-sections of at least 2.5 mm² for lengths up to 3 m and at least 4 mm² for lengths above 3 m.
Interestingly, the table present in the printed manual is not present in the one on the internet. IIRC, recommendation for 100W up to 3m was 3mm² or 4mm² at minimum.
From what I looked at, 14AWG is ~2mm² and 16AWG is 1.3mm². Way too skinny for what the manufacturer says.
Unless you're running speaker cables parallel to some power cables, shielding is not a requirement from my experience. The cable I use is at [0]. I have a roll like this. Mine is thicker than 2.5mm² though.

Those numbers are also ridiculous. They’re recommending 13AWG or higher for a 3m run. That’s about 20 feet round trip, which is about 0.04 ohms. The speaker should be 8 ohms nominal, but let’s call it 1 ohm at some very audible frequency to be conservative. So you might lose 2% of your power or maybe 0.1dB. Keep in mind that you cannot hear frequency-independent attention at all (the volume knob fixes it), so you’ll only hear the frequency-dependent part, which will be smaller, and your speaker plus room already has frequency dependence far in excess of 0.1dB. Note that the speaker power doesn’t even factor in to the calculation — as you supply more power, you’re increasing the current and voltage accordingly, and the effects cancel out.
At very high power you may care about heating. That recommended cable has an NEC ampacity of 15A or more, and 15A^2 * 8ohms = 1800W. Derate a bit because you’re at higher frequencies than 60Hz and you are just fine — in fact, the voltage will become a safety problem at silly power long before the resistive heating matters.
I will admit that there is a good reason to use at least 18AWG cable or so: speaker cable terminations are utter crap, and the crappiness seems to get worse as the fanciness goes up. A thicker wire is more likely to survive being terminated, within limits.
Buy some 16AWG two-conductor CL2 or CL2R or CL2P cable at your home improvement store and be done with it.

I have never heard mains hum coupled from a passive speaker cable. That’s not really a thing — there just isn’t enough power to make it audible under normal conditions.
You can get hum from ground loops which, given how hard it can be to track down, could end up being blamed on nearby mains wiring because you'll always have some sort of mains wiring in the vicinity of the audio gear in order to power it.
Right. I’ve never heard hum from a loop in the amplified wiring to a passive speaker. I did do the math, and it is certainly possible to arrange to couple in enough power to hear it without amplification, but this isn’t the norm.
I wouldn’t relate this directly to cognitive performance.
But my anecdotal experience working with younger employees / interns has been an uptick in situations where they become “paralyzed” by a fear of making a mistake, coupled with the inability to ask questions / seek out help.
They’ll google, or use ai, but if that doesn’t deliver an answer instead of asking a co worker, they will sit on an issue until someone follows up with them.
There also seems to be a huge fear of submitting “something” that’s not good enough where the preference seems to be “nothing” if they’re worried it’s not good enough.
I notice this in organizations I’ve been in leadership roles, but also have had this expressed to me by a half dozen peers in other organizations.
This is true - but it’s hard even for “good” drivers to always understand especially on roads they might not be familiar with.
Example: open space on either side of the road, tends to encourage people to drive faster.
Closing that space (whether by buildings, shrubbery, etc ) will slow the speed.
But I will say there are also “obvious” bad designs - the rare far to short on ramp to merge, where drivers don’t understand how to adjust.
Or the one I most frequently encounter are “blind spots” created by the speed of an intersecting road, where a mirror may be attached to a pole / tree, or a sign reminding people to look left right left, or even instructing where cars should be beyond for a safe pull out.
I know of one intersection near me that both has markers on the road(don’t pull out if cars are at or beyond this marker), and a reminder about looking, but still has a high frequency of accidents.
I’ve stopped using UPS except when I absolutely have to. I would say 10-20% of UPS packages have some delivery issue from damaged to lost.
USPS is sitting at 0 packages lost.
