The Ups And Downs Of RAM

After reading a few articles about the 30th anniversary of the introduction on the Apple Macintosh computer, I was a little surprised to be reminded that the original Mac only had 128KB of RAM. That's 128KB, not 128MB (most PCs now have at least 4GB, by comparison). The original crop of personal computers were 8-bit systems - so they could not really use a whole lot of RAM anyway. Applications were small too, as were disk space requirements. Over time, we got 16-, 32- and 64-bit systems, each able to access (and to require) more RAM. Programs got more complex, and grew to gobble up whatever extra RAM and CPU performance was available.


However, when smartphones and tablets became so insanely popular, they brought with them the low power requirements of mobile devices. The amount of RAM in these types of devices might only be 256MB or 512MB in the first round of devices, and currently perhaps 2GB in the more upscale tablet models. The Apps shrunk down too, as did the the available local storage.

As technology tends to do though, we are on the road to more RAM and more performance again, as Apple brought us a 64-bit processor in the latest iPhone, and we should see 64-bit Android devices this year. If I am blessed enough to be around in another 10 or 20 years, I'll probably be looking back at 64-bit as being really quaint...

VPN Use Is Up, Up, Up

Since the repeal of the Broadband Consumer Privacy Rules, VPN use and traffic is rather predictably spiking, according to many VPN providers. VPNs are not the b-all and end-all of privacy though, and indeed the usual cretins have stepped in to provide shady VPN services that may actually sell on user data.

Also remember:
ISPs still track your location data and DNS records, even if you're using a VPN. Similarly, a VPN doesn't stop a company from using on-device snoopware to track you (remember Carrier IQ?). Neither will it stop ISPs from charging you a premium for privacy (something both AT&T and Comcast have already experimented with). Nor will a VPN stop a company from using your credit score to provide worse customer service (something CableONE has crowed about). DSL Reports

Microsoft's Mild Mea Culpa Over Windows 10 Obscure Upgrade "Choice"

In a cleansing act before the turn of the year, a Microsoft bigwig has admitted that they may have gotten a little carried away in their zeal to upgrade as many users as possible to Windows 10.
Specifically, Chief Marketing Officer Chris Capossela referred to the upgrade notification that appeared to be deliberately deceptive in the way it handled a users response. If a user clicked the red "X" at the top right of the notice, that closed the dialog box but went ahead and installed the upgrade anyway.
To actually not accept the upgrade, you had to click a link in the notification window itself. Not a few users would come back later and find their system upgraded to Windows 10, or in the process of doing so, when they thought they had expressed their wish not to do so. "Within a couple of hours of that hitting the world, with the listening systems we have, we knew that we had gone too far and then, of course, it takes some time to roll out the update that changes that …

pCloud Cloud Storage On Linux

As a cheapskate user of the Dropbox free plan, I was looking to see if there was another provider that offered a little more free storage than the 2GB from Dropbox (I actually have 2.5GB, due to a couple of bonus offers).
After a bit of research, I came up with Swiss-based pCloud: it has a client for Linux, as well as Windows, Mac, iOS and Android. The free tier offers 10GB of Cloud storage with no file size limits, which is fantastic for my (pretty basic) needs. You can set up your account first from the pCloud website, or during the client install process.
