Consolidating databases has significant storage benefits – and therefore everyone should be doing it
My arguement against...
.. is (for my employer, at least) we buy packaged software, usually with little to no customization. Hence, We do have multiple copies of, say, a list of all employees, because most of the apps don't talk to anything but their own little database. For that reason, we use shared servers to reduce licensing costs, administration headaches (fewer servers to backup and maintain), and we keep tight control over who has server admin rights.
the few apps that we do have major customization on (mainly because they are sold to us that way) are generally their own silos, so if their app decides to start eating database processor time like a fat man at a pasta bar, it doesn't bring down half the apps in the company.
Granted, odds are the database servers are living on the same storage appliance, possibly even the same volume....
My spin on this...
Background: the environment we have consists of multiple database servers, most of them shared, and for the large part not using native clustering. We have a couple silo'd apps that use their own database servers because they are very transaction heavy, and the vendor's coding on the client side is... less than optimal, to put it politely*.
All of the sql servers are virtualized, using a mostly standard virtual machine, but with the data, log, and tempDB files on not only seperate 'disks' , but separate virtual SAS/SCSI controllers within the VM. (i.e., the OS sees four controllers, with one or two disks on each). We've also done some shenanigans with the cluster size on the disks as well at the OS level. These are stored on the same flash/SSD accelerated rotating storage arrays. For the large part, the apps on the shared sql servers don't notice or care. The few apps that we do see performance issues on are the LOB apps that have their own silo of SQL servers, and we spent a couple months going around with the vendor before coming to the conclusion that their queries are crap along with their database design and lack of good index placement.
Consolidation of databases onto shared servers are good, but care MUST be taken with what's put on them, and a competent DBA and system admin need to oversee and maintain them.
* This is the same vendor that I may have mentioned had a habit of going "our code is fine, your hardware SUCKS- throw more hardware at it!!!" only to find out that their databases had no indexes on the tables that were getting pounded on, and their queries were being structured as "SELECT * from *" and using WHERE clauses to filter the results for the data they wanted. They've gotten better over the last five years as we've called them out on rather a lot of their crappy practices and they've gotten competent staff in who are fixing a lot of the design problems we've pointed out to them. But I'm still going to make fun of them, because. :)

I'd be happy with knowing that I can buy that little coupler dingus for the gen 1 Pencil without having to either a) grovel to Applecare, b) grovel to someone at their genius bar, or c) buy one of the 84713 knock off clones on amazon. (or, for that matter, a new cap.)

The Honor MagicBook Pro looks nice, runs like a dream, and isn't too expensive either. What more could you want?
No, that's SOP for Sony VAIOs, at least their notebooks. I had one a number of years ago that had a tendency to BSOD due to a fault in the video driver; problem is, I couldn't use the standard ATI Radeon driver kits, because Sony did something to the GPU's firmware that made the Radeon drivers refuse to install, so I was stuck with the crappy, buggy driver that Sony had for it. Shame, it was an otherwise decent laptop, too.

Exchange (in a DAG) is also like this, along with other things, like restoring mailboxes, exporting mailboxes, etc. In my documentation for testing a DAG failover with Exchange, there's several places where it notes that a healthy dose of patience is needed. One step literally says "Go get a cup of coffee/water/tea/soda/etc."

Like performing remediation on the production vmware servers of real or imagined 'defects' (like disabling copy/paste from the console on an esx5 host, which has that function turned OFF by default to the point that the flag isn't in the vmx file.)
ON CHRISTMAS DAY. IN THE MIDDLE OF THE AFTERNOON.
[RedactedCo] is a 24/7/365 shop, so we are open for business every day; the nature of the business means that holidays are generally amongst the busiest times on the production floor.
Since I was doing remote work at the time to care for a family member that had major surgery, I replied back to him via email, with his boss (the CIO, and a sensible person) simply that no, that's not going to happen, but if he's insistent on it, to put it in writing, and I would start with the VMs that are running the production floor, and that each one has to be powered off first in order for me to add the toggle to the vmx file, which is about a 10-15 minute downtime for each server.
I then disconnected from the work network, turned off the laptop, and spent the rest of the day unmolested apart from the CIO going "you were joking, right? I'll deal with him" via text message.
I think. I have holes in my memory from that boss, he was extremely toxic.

They are absolutely screwing themselves over if they are insisting on using a deprecated certificate authority. Unless they've done something completely outside best practices (like making the CA root have an expiration date of 100 years or something equally stupid), they should be using something at least supported, especially if they are paying MS for support on it. And TBH, it's not too difficult to stand up a new CA next to an old one, which is useful if the CA's name needs to be changed or some such. (That's the route [RedactedCo] took moving away from a SHA-1 signed certificate with a tiny key length- We decided to stand up a new CA that exceeded best practices in terms of algorithm and key length, and just let the old one expire out. (We did have to remove it later on from the environment which was a little shaky, but our AD has a decent amount of cruft in it already from nearly 20 years of existence and a number of admins and people who thought they were admins messing around in it.)

Re: Redefine it
That sounds like an expensive plumber's bill, although I had to have the entire drain line from the kitchen sink to the main drain line in the front yard re-done after ~30-40 years of hot water, grease, and bog only knows what else finally ate through the cast iron part of the line. Had to have the front yard trenched, and part of the front porch saw cut. that was about 3-4 thousand US pesos. I at least got a main line cleanout plug installed in the yard for my money, so there was that.
(The previous owners were cheapsakes and did half-assed fixes whenever possible instead of paying the appropriate money and doing it right the first time. Had I known that, I would have passed on this house.)

Re: the Democrats should have won easily
I think part of it is that they are acting like they have higher morals. In addition, there was enough in-fighting within the DNC during the last election which pretty much prevented a unified front, which is what they absolutely must do this year.
Personally, I don't like either candidate, but I'd rather take an unknown with morals than the lying, narcissistic, sociopathic impeached crook we currently have.

Re: Dress Code
My 'interview' outfit has been my suit jacket, white long-sleeved button down shirt, a neutral tie, my nicest pair of black trousers ('docker' style pants for the USAians) and dress shoes. Seems to work well enough.
Oddly enough, that's the same outfit I use for funerals and formal weddings.
Re: Inappropriate garb? Me? Probably daily ...
I'd do it under the provisio that I get a clothing stipend as that will destroy the nice clothes rather quickly.
My current employer has a 'no jeans' rule as well, but it's at management's discretion, and several of our departments and teams are exempt (like the telecomms team). Fortunately, it's business casual, so we can largely get away with docker style pants, which are more rugged (and cheaper) than suit pants. (although things like cargo pants don't fly for some stupid reason...)
Appeals judges toss out FTC win: What Qualcomm did to its rivals was 'hypercompetitive, not anticompetitive'
A really good example is the v.90 standard for 56K modems back in the mid 90's. There were essentially two companies out there that had a viable process: 3Com/US Robotic's X2 and Rockwell/Lucent/Motorola's 56Kflex. v.90 (and later, v.92) took bits from both (to hear USR's response, v.90 was mostly X2 but with some 56Kflex sauce stirred in; I imagine the same was said on the other side as well), and was incompatible with both.
I know that Cisco is one of the 40 tonne kaiju in the internet standards realm, which is certainly a pain at times, because they have their own special way of doing things.... (Microsoft was also one in the past, and probably still are.)

Re: Customers are committed for the long-haul
Very much this. replacing a VDI solution also often requires a (literal) forklift upgrade/replacement of hardware as well as software. Even if the thin clients support all three of the big players (Citrix, Horizon, RemoteApp (aka RDP), it's generally a pain in the gluteus maximus to implement and migrate from one to the other. And none of the three I mentioned are 'simple, easy' solutions- lots of moving parts and a complex configuration, even for something simple and straightforward, like providing vendors with access for remote support.

Re: Which internet router encrypts traffic?
Operators that do value their traffic - i.e. TV broadcaster - do encrypt it.
Yep. There was a decent trade for a while with some of the people I used to work with many years ago pirating DirecTV signals; apparently, the decryption scheme they were using had some flaws in it or some such. I was never really interested at the time, so I didn't bother finding out more.

Backing up the database before upgrades or major updates is also a good technique/habit as well. It's saved our bacon a couple times at [RedactedCo] when the vendor ran an update to their software which included a database update, and then found that our specific instance of their software install broke their update, which required a rollback.

Burn baby burn, plastic inferno! Infosec researchers turn 3D printers into self-immolating suicide machines
Re: old story is new again
Pretty much any modern laser printer that uses toner also has a fuser to melt the toner into the paper. Now, normally the hot roller in the fuser assembly is coated with something like teflon to keep the paper and toner from sticking to it, but paper's really freaking abrasive over time, and the teflon wears out. (which is why you'll get repeat defects of a certain size when the fuser's old and needs replacement.)
One thing that I had to do a number of years ago was to crack open a brand new color laser printer, because some chucklehead ran a sheet of printable iron-on transfer paper through the printer, thinking it was for an inkjet.
Narrator voice: It wasn't.
The iron on transfer melted to itself and wrapped around the fuser. I was able to fix it, but still....
Also, laser printer do have a thermal cutout (or should!) for the fuser, although I've never seen one trip.
Getting back on topic: I have a couple 3d printers; both are powered off until I'm ready to use them, and I also don't leave the house while they are running, because fire hazard. (also, cats.)

Re: Lost count
See, that's a training issue, and the person handing over the laptop and dock should have taken a couple minutes to explain how to dock and undock the kit.
Unless the line manager was one of those "I work in the technology, and therefore I understand how all this works, despite the fact that this is brand new kit that I've never seen before" people who shoved the tech out the door 500 msecs after getting everything plugged in and powered up....
One hopes it was taken out of his check, or his department's budget.
If you own one of these 45 Netgear devices, replace it: Kit maker won't patch vulnerable gear despite live proof-of-concept code
Re: Thank you Netgear
Yep. They cranked out a model of their Nighthawk X6S for one of the warehouse club chains, the model R7960P. Apparently, a large number of these have a problem where they don't actually save their configuration properly, so when the power is removed from the device, it resets back to factory. Netgear's official response was "pay us XX for a support ticket, and we'll RMA it with another unit that may or may not have the same exact problem". And while I could take it back to the warehouse club to RMA it there, (this particular chain has a fairly generous returns policy!), it was easier for me to just buy something else that was DD-WRT compatible (a TP-Link AC1750, which has a 'beta' firmware on DDWRT that seems to work just fine.)
Linksys was crap since cisco bought them, although I will state that I have a stack of D-WRT'd WRT-54G/GL routers that work rather well, despite being very obsolete. (which was the primary driving force behind getting something that supported both 2.4 and 5Ghz radios and was a little more modern.)

Re: Trump'S Getting Worse
There's been a rumor flying around that he had a minor stroke a few months back during that 'unexpected health checkup' that occurred.
Personally, I had the Orange One's personalty pegged years ago- he's a narcissistic, sociopathic con-artist who does'nt give a load of dingo's kidneys what happens to anyone else but him, as long as he's made out to look good. (which means that 'world leader' is absolutely the worst job to have.)
