Comment Isn't it obvious why they're doing this? (Score 5, Insightful) 275

Microsoft wants to make using older versions of Windows as annoying as possible for IT departments, to try to push us to move to Windows 10.

Corporate IT departments tend to be the biggest holdouts for moving to new versions of Windows. If a business is running fine on Windows 7, there is ZERO reason beyond security updates to move to Windows 10. Now they're giving us an artificial reason: If a rolled up update breaks something, we have to roll back the ENTIRE batch. Even any included security updates.

Microsoft wants their licensing revenue, and they want fewer versions of Windows to support. This is their play.

You're quibbling over semantics, now. I consider their whole line of notebooks to be "Macbooks". That's probably what OP meant.

I'd ask the OP to clear it up, but at this point who cares? This isn't a topic that has people on the edge of their seat awaiting a resolution. :)

Comment Re:"allows you to download a 5GB HD movie in 40 se (Score 1) 93

You can still buy a movie on iTunes and legally download it to your computer.

Don't know how many people still do this; it usually doesn't cost less than the Bluray so if I'm going to outright buy a movie I'd rather just get the physical disc, which almost always includes a download code anyway these days.

Comment Re:VPN (Score 4, Informative) 71

A regular public WiFi, that you can connect to without installing profiles, etc... is indeed unencrypted. But most services that matter these days use SSL so it's not an issue.

But if you have to install a profile, it can do things like set proxies, install SSL client certificates and so on. It can spy on you VERY deeply. You're actually better off connecting to unencrypted open WiFi than one of these.

Comment I went to use one of these... (Score 5, Informative) 71

I went to use one of these and it wanted to install an iOS configuration profile on my phone.

These profiles can configure your phone on a fairly deep level, doing things like adding proxies, restricting functionality, and so on.

I hit cancel and just continued to use my data plan. Screw that.

Ars Technica allows 30 minutes, I believe, and it doesn't seem to be abused. People that reply will quote the bit they reply to so it's clear what they refer to anyway.

So how about 30 minutes editing window, and a quick, one-button-press to quote the parent post? Just to encourage people to include the original bits in their replies?

For added protection you could colour the edited text in dark purple, say, just to make it clear to people what has been edited?

I read this and I'm just shaking my head at how incredibly ludicrous every word in that statement was.

If it weren't for the fact that millions of people live under the oppression of this sort of thinking, it would actually be funny.

When will these people finally join the 21st century and stop basing their entire lives around this bullshit?

Comment Re:Foolish Investment? (Score 1) 124

Yeah, Golden Beach, FL has this problem. Over a mile of beach with absolutely no public access, except for a small park in the middle where you can't park unless you're a town resident and the police will harass you if you use the facilities there.

Beaches should be public. Period. They are a very limited resource and it shouldn't be possible for the 1% to own them and deny access.

Comment Who the heck watches porn at McDonald's? (Score 2) 284

I've eaten at McD's many times and not once have I seen someone watching porn there. Also, it's not the sort of environment that makes sense for watching that content; you don't have any privacy to do the sort of things that someone watching porn tends to want to do.

What's the point?

Well, yes and no. You're limited to 100Mbit/s, which is if course a lot slower than gigabit ethernet, But normally a scientific cluster (which is what I'm interested in) isn't really limited by bandwidth as much as by latency. Going through the USB subsystem for all packets is going to give you worse latency than dedicated hardware. But then, I also use a cheap switch that's probably not a speed demon for retransmitting packets either.

And the thing is, the Pi is a fairly slow computer. I suspect that as a ratio of computing speed to transmission delays, the Pi has as effective communication as a "real" cluster of server systems connected with high-end hardware. The CPU is even slower than the network if you will.

Any particular reason not to just do it in software, e.g xenserver or virtualbox? Virtual networking is kind of messy, but it leaves less cables around :)

VMs would work well, I agree. But this way I also get real(ish) network latency and delays in the same way a full-size system does. And an actual tiny cluster on my desk is a lot more fun :)

Comment Re:Great (Score 1) 89

It's really easy to set up. Take a few Pi's, add a small switch (get one that takes 5V). Connect them up, and use a single larger power brick that can power all Pis and the switch. Either make some kind of enclosure, or - as I did - rack them up with spacers, drill holes in the switch lid and mount the rack of PI's to it.

One wrinkle is that you probably want to keep the switch only for the internal network. I use a USB-Ethernet dongle on the login node for external communication. it's just as fast as the on-board Ethernet in practice (it's internally treated as a USB device anyhow), and you can set up the login node to act as router and gateway to the other nodes.

Then you can install and play with whatever cluster-related software you like: Slurm, OpenMPI, Ansible, GNU Modules, XscalableMP, ZeroMQ and so on.
