Overall the article is pretty good. But be careful that an example doesn't derail the point.

I never knew that either? That is amazing and would certainly explain why users sometimes complain about poor performance! That would be a reason to discourage people to dump everything on their desktop. But that would be the only reason. Otherwise, my view is, I don't like users doing it, but if that's what they like and it's not hurting anyone, I'll do my best to accommodate them.
To take @thanksajdotcom's doctor analogy - sometimes my users are a patient (when their PC isn't performing), but sometimes they are a customer. If the desktop causes performance issues, then I'll be their doctor and tell them not to do it. If the desktop doesn't cause performance issues, then they'll be my customer. Kind of like "if you want extra cheese on your burger, then I'm happy to do that for you, sir", but "if you want cyanide on your burger them I'm going to have to say 'no".

I've heard this from a few people. From the research I've done it never seemed to actually be the case. The only thing that was put into RAM were the objects in the Startup folder and the system services.
Now to A.J.'s point. Placing restored files on the desktop really doesn't make sense as you can easily drag/drop those files into the correct library location.

It definitely has the sound of an urban legend. Can't figure out why they would cripple the system that way and why there wouldn't be all kinds of confirmation from them if that was done.

You can test it yourself actually... throw a big file onto your desktop and monitor RAM usage... I just did it with the ~5GB Fedora 18 ISO. It used 200Mb of RAM for the copy and then went back down to what I was using before.

@coliver Actually that could still cause it to cache because of the transfer. Need to reboot to really be sure. But if it doesn't do it in the transfer, it definitely doesn't load it.

I didn't see that behavior, but you're right that could happen.

When you read the article and post a question about it, then read down the comments and see it's been asked below. Sigh.

What's odd, generally with IT stuff there is an answer generally accepted by the community as a whole. Things like RAID 5 is bad. This however has no consensus. Even though it seems to be fairly easy to test.

Even worse, is it makes a certain kind of terrible sense. It'd be useful to have a space where you put your working files that's a RAM drive mirrored to physical disk. Write out the changes every 30 seconds or something so you don't thrash I/O on the disk and still get all the benefits of insta-run stuff.

Doesn't the system already kind of do this in a more automatic way? It caches documents/files that you are currently working on? Having a central "RAM Disk" to do this would be gimping the operating system automatic processes.

If it does I'd be interested to know about it. Obviously it does when you open the file, but that's what we're trying to avoid (the comparatively slow disk I/O).

I've been doing that since the Amiga days. Just get an SSD today, though.

You want tiering with an auto-load to RAM disk, I guess?

The Wallpaper has been for years, Never heard of the desktop itself being in ram though.

Y'all get so complicated lol
I'd take a simple folder that's mirrored to disk. Mirroring is important to me because I usually care about keeping what I work with, but like Office's auto-save it could be something basic like twice a minute.
Now I'm going to spend the rest of the day setting up a RAM drive and writing a script. Sigh.

I'm not sure how much I can agree with this line The job of an IT Professional is to fix, document, and improve. We fix things that are broken..
That sounds more like a Technician. I would say an IT Professional's job is to apply technology to the business process.

In similar light to the article's title... I've always heard of the seen words ofa dying business: "We've never done it that way before."
Similar in light to the "That's how we've always done it" -- only different.
Doing things because that's the way they have always been done without questioning it is when that becomes a problem. "That's how we've always done it."
What about this way?
"We've never done it that way before."
Why not?

But aren't we often applying technology to improve or fix a broken process?
