Comment: Ubuntu maybe, but Kubuntu on the other hand... (Score 3, Interesting) 272

I've been using kubuntu everywhere: home, work and family computers. For the past few (at least 5) years, upgrades have been smooth with very few minor bugs since the kde3 -> kde4. But this time it's close to a disaster on the only machine I upgraded. They didn't do small incremental changes this time, they updated: kde4->kde5, qt4->qt5 (or the framework), whatever->systemd, lightdm->sddm.

I think the latter is the cause of all the graphic problems I've been having. If I use the fglrx graphic driver (for AMD/ATI), I cannot sleep anymore (it wakes up to a black screen) and I don't have ctrl-alt-F consoles anymore. If I use the xserver-xorg-video-ati driver, I cannot unlock the screen (it loops back to sddm). Which makes having a laptop rather useless.

And there are plenty of other issues: opened windows are lost between logins (or moved to random places, and always to the 1st desktop), all opened konsoles are lost, kate doesn't reopen files, some login screens are all white. Or all black. The date on the clock is too big and doesn't fit ! And one thing that ails me is that your preferences are not kept between KDE4 and 5. You have to spend an hour or way more to go through all the options to try and get the desktop the way you want it again.

Before I met my GF's mom, she told me that her mom looked much younger than she was, without telling me her age (or I forgot). So when I met her, she proudly asked me how old I thought she was. As a good programmer, I compensated knowing the way the bias went, and gave her a good decade more than she actually was. She didn't appreciate. Yeah, social skills, blah, blah, blah...

But, if they call it an engine, it must have a lot more specific impulse / momentum than just beaming microwaves off the back of the device. You CAN move by pointing a flashlight the opposite way (in space), but the acceleration is so low that you'll be dead of old age before you've moved a meter. So this must clearly be different and quite a few orders of magnitude better.

Comment: I would have said one... (Score 1) 301

...until I recently got a brand new laptop. The internal wifi cannot work properly at the same time than the internal bluetooth (thanks Dell!), so I need to disable one in the BIOS and add a USB wart. Then with all the variants USB2, USB SuperSpeed, USB3, USB Power, to which to add eSata with possible USB, all of those incompatible in mysterious ways, that makes at least 6.

An intelligent person from say Pharonic times, would be able to understand modern technology after some exposure to it.

It's something that somewhat pissed me off in the movie The Mummy: they used Imhotep as the bad mummy came back to life. It's an insult to that guy who was a true genius of Galileo/Newton/Einstein caliber. 5 millennia ago he wrote medical texts, built the very first pyramid (still standing), invented collumns, performed surgery, astronomy, poetry, philosophy, was a prime minister, was born a commoner but was accorded divine status after his death... One of his diagnostics is still used in current medical textbooks. Come one Hollywood, have some respect ! OK, besides that, the film was halfway decent.

Proprietary (and supported)

Well, if only that was true... I remember a long time ago (Win95 ?) I applied a service pack in a different language than the OS. The result was a clusterfuck. I called MS and from the conversation I could tell that something wasn't right. After a while I asked: "It sounds like you think I'm using a pirated version", which I wasn't (full on-site license with hundreds of seats). I think it was my beginning of a search for something better.

TL;DR: Attempting to artificially create a human language is a complete waste of time.

Right on the money. The only artificial language I did find interesting is one whose premise that you could use any word that exists in at least 4 European languages. I think it was Interlingua, but I can't find its specs right now. I did find it very easy to read. But then a chinese or bantu wouldn't understand a word anyway, so why bother ?

Nondeterminism means never having to say you are wrong.
