Re: I will put up with the occasional reboot

"Your uptime represents the amount of time since you last tested your startup."

And my long term health represents the amount of time since I last tested my immune system. I don't want to get sick to test how good I am at getting better thank you very much.

I also don't want to lose all my data to test my backup/recovery process. Sure, I'll schedule it in on my own planned schedule; when it's convenient for me. Maybe I'll eat something a little bit "iffy" tonight to test my digestive system...

Linux

Re: Indeed

Why don't you just use Linux, it does everything and it's free. It even orders your round in at the bar while you don't even wait for the ticks, cause it's all fully hidden away and automated (if you like that sort of thing)

YES, I have ridden the UNICORN: The Ubuntu Utopic unicorn

DanDanDan

Re: so many versions

You'll only get downvoted if people think your question is rhetorical.

Your main problem with lacking understanding of "What is Linux" comes down, probably, through lack of experimentation and experience of it.

Linux is, at its core, just a way of bringing together hardware interfaces with software ones. That's the kernel: it manages memory usage, separation of separate "programs", etc. It's all the invisible stuff that you don't think about. On top of that, you can place whatever you want.

Most people place free and open source (FOSS) software on top, which has sort of been known as "Gnu/Linux", since a lot of software that falls into this category and is used is made by Gnu. It was originally intended as a unix clone, but has now grown its own wings and deviated significantly.

A collection of different software and configurations is known as a Linux distribution ("Distro"), of which Ubuntu is one, Fedora is another, Red Hat is a 3rd, Debian, Gentoo, etc. They're all just subtly different ways of pulling together a whole system, which is useable by someone like you to run things like a Web Browser or Office program.

The main topic of this article was "Window Managers". These are what you would recognise as "The Desktop + Start Menu". There are a few of these about, the main traditional ones being KDE and Gnome. Basically, different people have different preferences, so they prefer different Window Managers. If you think about the difference between Windows 7 and Windows 8, the main differences that you see will be in the Window Manager used. Android could be argued to be another window manager, designed primarily for mobile application.

The best way to find what you like is to install a couple of versions (probably in a virtual environment for ease) and give them a go. You can even run many different versions from USB stick; no installation required!

Brother, can you spare a DIME for holy grail of secure webmail?

DanDanDan

Re: Key management

Doctor Syntax - you may want to read up on the importance of authentication in asymmetric key crypto. i.e. How do you know you're sending the message to Alice and not Charlie? If you can't validate the authenticity of the public key (i.e. that it definitely *is* Alice's), then you're wide open to man-in-the-middle attacks.

The other thing is that quantum computing threatens to undermine the whole P=NP robustness of many asymmetric key crypto. And you can bet the NSA are somewhere in the frontline of getting this stuff working (if they haven't already).

This could actually alleviate many of the problems with short battery life and long charge times. I had the idea of just using plug-n-play batteries, that you trade in at petrol stations; but then found out almost the whole car is made of battery. However, something like a hire-car scheme where you can pick up a car at a charge point and drop it off at one closer to your destination: that just might work.

Cambridge Assessment exams CHAOS: Computing students' work may be BINNED

DanDanDan

Re: GCSE Computing still a joke????

"A level maths and physics don't have this diffuseness."

Uh... yes they do. Pick and choose which modules you'd like to do in maths/physics. In maths, there was a choice of stats, decision and discrete (i.e. algorithms, linear programming and graph theory), mechanics or numerical analysis. In physics, there was a choice of quantum, relativity or... something else that I don't remember. In addition to certain core modules (in maths, this was things like calculus and geometry and in physics this was things like mechanics).

Computing is (or rather should be) quite a tricky subject in actuality. Taking account of the limitations of teachers is just pandering to a lack of teaching ability. They should be hiring decent computer-literate people, not asking the maths teacher to teach a bit of computing on the side, in addition to their already full schedule. Computing is being treated like PE and we'll end up struggling as a result in the future, in a tech-oriented world in which we really could thrive.

Massive news in the micro-world: a hexaquark particle

Re: Neutron decay

@Destroy All Monsters

While you might be right, you might also be wrong. It's been a while since I did much actual computation with quantum physics, but I remember Feynman's 3rd volume showing how the exchange of "Virtual" photons binds stuff together (he shows a lot with simple two state systems). It wouldn't surprise me if the binding force between neutron and proton was in some manner comprised of the exchange of the "virtual" electron contained in the neutron in an atom. This would lead to a lower energy state when they're combined and that would back up your claim of "The reason that neutrons do not decay... is because doing so would result in a nucleus with HIGHER energy".

Either way, it might be an interesting calculation...

EDIT: Ignore that - Heisenberg tried it already:

Robotics pioneer: Intelligent machines are 'scary for a lot of people'

DanDanDan

Re: More AI Fluff and emty promises

And the Eurofighter...

I can fully understand why you want your industrial robot to do the same thing time and time again in a well-defined model. As for the example in the text, I don't want my robot to drop stuff in the first place. If it does, that should be a special case scenario and it should just stop, waiting for an engineer to come along and find out why it didn't work as expected (broken sensor, lack of vacuum, something in the way?) There are an almost infinite range of possibilities that may be encountered by a robot (someone might have confused one of its sensors to bypass some normal behaviour for example) and it makes its decisions based on *its own interpretation of reality*. That sounds dangerous to me. Unless it can *know* that "something's a bit fishy here guys", then it's not safe for it to be making its own decisions.

Achtung! Use maths to smash the German tank problem – and your rival

Re: 1+1/E seems dubious for low values of E

There's no "lower bound" as such, but you want to have enough samples to be confident in your estimation of N.

You're looking for information on "Confidence Interval" Check out the best answer from the below page. It details how to find the confidence interval of the maximum likelihood estimators for "a" and "b", where a and b are the lower and upper bound of the distribution.

Re: Bitcoin is strongly deflationary

"Moderate inflation is a good thing". It's good if you're in debt, yes. If you've worked hard for your money and saved a bit away for a rainy day (like a sensible person is advised to do), then it screws you over. It's a tax on savers. It encourages spending and debt and financial inability. I hate inflation and wish we'd stop trying to curtail it. If we start getting to a point where we're on the cusp of deflation, we can just print more money (like Japan did).

I don't buy the idea of permanent deflation either - I think it only lasts long enough to deflate whatever bubble has been building up for so long. It's the bubble that's the problem, not the boom. Bitcoin is one such bubble - it's a pyramid scheme by any other name. I don't understand why no-one else seems to notice this. Lack of transparency + technology seems to be the equation for bubble-building these days and it seems like the only sensible thing to do is to buy into it on the basis that govt. will support those who invest unwisely (as has been evidenced multiple times in the last decade).

Austrian economics is pretty much common sense when you think about it, I don't get why it comes under such fire (well I do, it's because Keynesian economics works on about the same time-frame as political voting systems). Traditional Austrian economics would *NOT* support bitcoin as you seem to suggest!

OpenSSL bug hunt: Find NEXT Heartbleed, earn $$$ – if enough people donate cash

DanDanDan

Re: Open Source Funding...

The same thing that prevented forked OpenOffice (LibreOffice) from devolving... better project management by a better team, with more outside involvement and input. It wouldn't be easy to do (which is why it's not been done yet I suspect).

Re: Open Source Funding...

From what I hear, OpenSSL has a small (half a dozen) group of core developers who reject any and all outside contributions in terms of bug fixes, etc.

They also have a TERRIBLY HORRIBLE code base (think #if 0 everywhere), barely any evidence anything has been refactored and barely readable code, with feck all comments in it.

Frankly, it needs to be forked and the forked version needs funding from the megacorps who profit from the code. They can all benefit from open source by sharing the development cost and shared benefit.

Web data BLEEDOUT: Users to feel the pain as Heartbleed bug revealed

DanDanDan

Re: Simple solution

"But have they issued a patch yet?"

Uh, yes... Patched on the 8th of April, but compiling from source is not difficult either.

Confirming whether you're safe or not is as simple as:

# opkg list | grep openssl

Updating to the latest version is as easy as

# wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/libopenssl_1.0.1g-1_ar71xx.ipk

# wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/openssl-util_1.0.1g-1_ar71xx.ipk

# opkg install libopenssl_1.0.1g-1_ar71xx.ipk

# opkg install openssl-util_1.0.1g-1_ar71xx.ipk

# reboot

As far as "It was open source that caused the problem in the first case" - I don't even know whether to bother explaining the errors in logic. How does publishing the source code of a program cause it to be insecure? Either it's secure or it's not.

Ask yourself:

•Can I easily find out if my router is running OpenSSL, and if so what version? (Answer: probably no)

- With OpenWRT this is pretty easy

•Can I easily upgrade to a secure version? (Answer: only if my vendor or the ISP that provided the hardware ships a firmware upgrade)

- With OpenWRT this is pretty easy

•Will old devices get upgraded? (Answer: probably not in a hurry and almost certainly not automatically)

- With OpenWRT this is pretty easy

•What can I do? (Answer: turn off remote management, if you can).

- Keep using open source router firmware? :)
