Comment A few obvious corrections (Score 1) 48

First, DES is 56 bit (near enough 60). Triple DES as per first mode (the authorised standard) is 168 bits. The article fails to distinguish, implying the authors are just a little bit naff. 3DES seems to be quite safe, as long as not used in DES emulation mode. And who the hell emulates a mode that was broken in the 80s?

Second, Blowfish was replaced by TwoFish, ThreeFish and Speck. Skein, an entrant to the DES3 challenge, makes use of ThreeFish.

Third, the Wikipedia page states it has been known for a long time that weak keys are bad. This particular attack, though, is a birthday attack. You can find all the ciphers vulnerable or free that you should be using. Anything not on the list is something you are solely responsible for.

In other words, this information is about as useful as telling up that Model T Fords weren't good at cornering at highway speeds. Below are some links, I can't be buggered to HTML-ify them.

I do not trust most encryption software these days, but that's because programmers these days are sloppy and arrogant.

"So I'm afraid I must repeat (and I take no pleasure in saying this, believe me) your only three options this election are Trump, Clinton, or throwing your vote away."

If you vote for someone you believe in, your vote is never thrown away. They may not win, but people will see how much support they get, and that can lead to more support next time. You are right though, that FPTP is a poor system. It's particularly poor when it comes to electing presidents because (as far as I understand it), it is not possible for two candidates to combine their votes in any way, unlike parties which can combine their votes and form a coalition. The upshot of this is that people like Bernie Sanders won't risk standing as an independent for risk of splitting the left wing vote. You could have a system where candidates can pledge to transfer their votes to another candidate in the event they fail to secure enough votes themselves. It could bring an end to the endless oscillation between Republican and Democrat presidents.

Any battery developed by Dyson will no doubt be massively overpriced like their other products. Even if he were able to double the energy density of batteries, it seems likely you would be able to buy several of the conventional batteries for the same price.

Besides which, it looks like there is already quite a breakthrough happening right now. http://news.mit.edu/2016/lithi...

The fact the whole state is a river flood plain and only stupid people build homes in a river flood plain?

Global warming may have cause the weather pattern changes, but it does not change the fact that if you build in the low lands, you have to expect flooding because it will absolutely happen with a 100% guarantee.

Comment Re:Travelling at 20% of the speed of light (Score 1) 218

I love the whole "it's only 20 years if you travel at 20% of the speed of light!" part. It makes it sound so close.

What's a human lifetime, anyway? Insignificant.

Let's say we set the bar a few orders of magnitude lower. Say, 0.15% the speed of light. Leave around the time the ancient pyramids of Egypt were built, arrive today.

Now pick something in between. Say, 1% the speed of light. One-way trip ~425 years. Is it so hard to imagine that in a # of decades, we might have probes able to accelerate to that speed? Now replace 'probe' with 'city-sized starship'. Something big enough to allow generations of people to grow up & have offspring. Decades of technological progress not enough? How about a century from now? Or 2 centuries?

In other words: all we need is patience, and imagination. And (as mankind) not be stupid enough to blow ourselves up before those spaceships are on their way. As long as travel group can sit out the ride, who cares if the actual trip time is 20, 200 or 2000 years.

Comment Re:I use Plasma (KDE) and system.d (Score 1) 512

I, on the other hand, love systemd on my Kubuntu 16.04 with Neon running on top. In System Settings, at the bottom, is the Systemd Icon. Open it and you have the GUI to start and stop all services with a mouse click, if you don't want to us the CLI.

Linux and KDE. They keep on giving you choices because one size does not fit all.

Comment Re:KDE-Look a ghost town (Score 1) 512

I love KDE4's look and feel, and am not partial to the default Plasma5 L&F. So, I changed themes, splash screens, wallpaper and icons and now I have my Kubuntu 16.04 with Neon on top looking pretty much like my old Kubuntu 14.04 DE, except that Plasma5 is at least TWICE as fast on my laptop as Plasma4 was.

Trolling like that it is no wonder you post anonymously.
I've been using KDE since 1.l0 beta in SuSE, in September of 1998. I tried Gnome but didn't like it and I have never had to install Gnome to get a KDE app to run. For a long time Gnome and KDE dev teams worked together to create a compatibility layer so that each could run the other's apps without having to install the entire DE. It's still that way. I don't have Gnome installed on my Kubuntu Neon 16.04 with 5.73 Plasma5, but I can install Synaptic and run it without installing Gnome, but I run Muon instead.

Your second claim is entirely bogus. Unless you are running Gentoo or Arch or LFS you rarely have to compile anything. VERY FEW apps installed from the repositories have to be compiled, but when they do it is done automatically without the aid of the user. Examples: VirtualBox requires dkms, which requires kernel headers and some compiling, but its all done on the fly during the install. All the user has to do is reboot to activate the change. Installing GoogleEarth causes an automatic recompile of the source but it, too, is automatic. So, requiring the user to be a developer and compile source is NOT part of any of top 100 or so distros, save for the rare exceptions I mentioned. Of course, if you insist on going outside the repository and downloading tar file sources of apps not in the repository then you will have to know how to do a) ./configure b) make c) make install. But NO distro developers I know require that for elements of their distro, save Arch, Gentoo and LFS, and those are not distros that everyday mom and pop users would run.

You stated "When there is a day, that someone can be handed a USB stick with a flavor of Linux that they can run from it,have all their hardware supported, without having to install, compile, or download anything, we will have finally a Linux OS that is at least comparable to Windows 95." How about comparable or even better than Win8 or Win10, and more open and free as well? I have such a USB stick in my pocket as I type. It is a persistent Kubuntu 16.04 LiveUSB. It is easy to make with the mksub app, which is also in Kubuntu's repository. The fact is, the top 100 or so distros in DistroWatch's page hit list are just the kind of distro you claim doesn't exist. There are always the corner or edge cases of hardware for which is difficult or impossible to find Linux drivers for, but if you've spent any time on Windows help forums you see the exact same problem, and that is with vendor configured copies of Windows.

So, better luck next time trying to conflate an experience you might have had with a Linux distro 15 years ago into what you think are problems today.
