Suggestions & Concerns / Re: Unofficial Debate Guidelines

You didn't even link to the thread you're talking about. I've already lost interest because you're expecting me to do all the work.

As in unless you're doing something illegal, why do you need to hide your IP address? And having a problem with them storing your online data, is like saying that a phone does the same thing, even though it says that they have the right to use browser and data information in a court. You sign away a lot of freedom while using electronics, and IP address can be shared throughout a large amount of people, IE a school or company. It makes zero sense to hide it. Is this a better statement?

No, it's a worse one. Nobody "signs away" anything by using a computer. You're confusing terms of use of specific online services with the use of a machine.

You don't need to be doing something illegal to worry about your IP address being stored, but hyperfocusing on the IP address part is probably why you're getting confused. Google collects too much information from too many different sources about people already. If we can do something small to anonymise that data a little bit better, such as obfuscating part of an IP address, that is an improvement.

I would be equally in favour of, say, anonymising user agents. The fact that we're talking about IP addresses is incidental.

43
You really don't need to hide your I.P Address if you're a normal citizen though...

This is too vague a statement to respond to. What do you mean by "hide your IP address"? You can't hide it in connections you make since it is what identifies you on the Internet, but there is quite a big difference between obfuscating your IP address with a proxy and having a megacorporation forever storing your every online move associated with your IP address.

44
Actually it really is Google's business. Google has a Privacy Policy page, and a Terms of Service page. Both state that google can collect information on you, I.P. Addresses included. If you have a problem with this, don't use the internet.

Or you can just, you know, configure your browser not to send your information to Google.

I use five privacy-related browser extensions:
  • Privacy Badger to dynamically detect and block trackers.
  • uBlock Origin, primarily an adblocker but also blocks some known trackers.
  • Decentraleyes, which caches static content from content providers locally to avoid passive tracking through the hosting of static files like jquery.
  • Cookie AutoDelete to delete cookies from (non-whitelisted) websites after I close their tab.
  • DuckDuckGo Privacy Essentials, which, aside from replacing the default search engine with DuckDuckGo, provides its own tracker-blocking functionality.
There are also others such as uMatrix which you can use if you're really paranoid, but they require more work to maintain. The five I listed above are set and forget.

Edit: I should add that Google Analytics is automatically blocked by three of these extensions (Privacy Badger, uBlock Origin and DuckDuckGo), so I don't get tracked by Google here regardless.

Technology & Information / My weekly 9front time
« on: May 09, 2018, 08:47:35 PM »
In the spirit of the last great OS contribution thread, I am now focusing my attention on an even better OS by the name of 9front. Since tomorrow is a public holiday here, I'm going to take the opportunity to get started.

Thursday, 10 May, 2018

Problems to fix
  • Investigate why the etheriwl driver will not associate to my home WiFi (while it works just fine with my phone's WiFi hotspot).
  • Fix some quirks in autocompletion in rio text windows.
  • Debug man -b.
  • Investigate having different tabstops for different sam windows.
  • Try out 9webdraw as a substitute for drawterm, and extend it to support dp9ik authentication.
Long-term investigation to start
  • Implement a RADOS 9p server, which could later be used to support CephFS mounts.

This isn't a debate forum.

This seems like a reasonable change and I'll try to get around to looking at it more closely this weekend and hopefully applying it. In the meantime, can everyone please refrain from giving me a reason to split the thread?

Edit: Split, because some people don't know how to take a hint.

Who cares, they're both shit companies. Regardless of which benefited more, you can be sure that one person who didn't benefit is you.

Update: A fellow 9front user on IRC has informed me that the Contour Mouse is actually really good. I trust people with a high enough IQ to understand Plan 9 way more than random Amazon reviews, and I haven't ordered an Evoluent yet, so the Contour is now my preference again.

3. Came with a sturdy little mouse that has a mouse wheel. I am not going to use it, but knowing I have one and Parsifal would like one can be chalked up as a little bonus.

I don't know which is worse, the fact that you think a mouse having a scrollwheel in 2018 is notable or the fact that you don't use a scrollwheel in 2018. Do you still just drag scrollbars around?

The Matrix (The Wachowski Brothers, 1999)

Hadn't seen this in years. Decided to rewatch it. Totally worth it, even if it is overflowing with clich├ęs.

I would happily use this if it were still available.

Isn't the CPU downgrading strictly as a power save feature and people like me who turn that off don't see it downstep?

Why would you turn that off? You don't need your CPU's full power 99% of the time, because most programs are very rarely CPU-bound. Operating systems are very good at increasing the clock rate when needed, so there's no (or negligible) performance impact. You're just wasting electricity, as Rushy says, and possibly also making your fan louder than it needs to be.

This is mind boggling nonsense. If my PC has a TDP of 65W, I can expect it to warm my PC as much as any other 65W TDP processor on any given day. I shouldn't expect it to run cooler than a 35W TDP processor of yesteryear.

So you actually don't know the difference between TDP and heat output. Colour me surprised.

And I rebutted that by saying my processor had TDP of 65W and therefore was no cooler than 65W desktop processors of 20 years ago.

Which is not necessarily correct. Have you considered the problem may be that you don't know the difference between TDP and heat output?

Show me TDP = power draw.

Nobody is saying that it does. That doesn't make your fantasy world in which CPUs absorb energy and violate fundamental laws of physics real.

And you are claiming that all of the petrol goes into heating the engine and none of the energy does into driving you anywhere.

If the CPU's job was to impart kinetic energy unto the computer, this might be a valid analogy to make. Unfortunately for you, a CPU does a negligible amount of useful work, for the physical definition of "work".

Stop talking about electrons. When it comes to the behaviour of electrical energy in a circuit, the individual charge carriers are irrelevant. What you are saying is equivalent to claiming that pollution in rush hour doesn't happen because the cars go back home at the end of the day.

You obviously don't have the basic foundational knowledge required to understand how electricity works. I'm far from an expert myself, of course, but I'm amazed you can get an engineering degree with so little understanding of... well, anything. Please just stop before you sap what remains of everyone else's IQ.

Well, some of the power is passed on to other components. CPU needs to talk to the ram? Needs to send electrical signals to it. Wants to talk to the GPU? More signals needed. Motherboard, resistors, signals to drives and other chips.

This is negligible, since the purpose of these signals is to transmit information and not power, so there isn't a lot of current involved. But more importantly, this will just be turned into waste heat when it reaches those components anyway, so it makes no difference to the total heat the system generates.

Some is lost to electro-magnetic radiation.

Which is a form of heat, albeit not one that needs to be extracted by a cooling system.

Some is noise, you can hear a CPU.

Not over a 10W speaker. Also negligible.

Some is vibration. If a CPU operates at 4GHz ... that's a lot of very shallow amplitude but high frequency oscillation. Imperceptible to you as a human, but guzzling power all the same.

4 GHz waves cannot permeate effectively in air. A 4 GHz sound wave in air has a wavelength of about 80 nm, which is short enough that it spans about 20 nitrogen molecules. You're playing pool with molecules at this point. This means the vibrations are never going to leave the computer, and therefore do not qualify as a form of loss.

Guess what happens to vibrations when they impart energy but don't travel very far as waves. Go on, you can think about this one for a bit.


Electrostatic losses when not all power send to capacitors/transistors reaches them.

Another form of heat...

These days even quantum tunneling is a loss. Not all your electrons do the thing they were sent to do.

"These days"? Are you aware that quantum tunneling didn't just spawn into existence when it was discovered?

Nevertheless, this is both negligible and irrelevant, since electrons are matter and not energy.

There are loads. A CPU isn't just made to generate heat.

Actually, that is literally what a CPU is designed to do. It's an entropy machine.

Are you familiar with the Second Law of Thermodynamics? It states that the total entropy of a closed system must always increase. Now consider what a computer is supposed to do. The job of a computer is to take disorganised data -- with high entropy -- and turn it into a form that can be easily accessed by humans -- with low entropy.

Now we have a problem. To do its job, a computer needs to reduce the total entropy in its memory banks. Since the entropy in a closed system cannot decrease, this means that the computer cannot be a closed system, and it must generate more entropy than it removes. The more entropy it generates, the better it performs.

This is the technical reason for the common sense correlation between higher TDP and better performance. When it comes to computers, better performance is more waste heat.
