IIRC this feature existed when 4 came out and it's been there since.
  1. Position and size your window as you want it in the future.
  2. Right click on the title bar
  3. More Actions:Special Window Settings
  4. Size and Position tab
  5. Check Position
  6. Change the dropdown to "Remember" (or force if you don't want it to be movable). Note that KDE recognizes the current size and position of the window. You can override these numbers if you like
  7. Do the same with Size
  8. Explore. There are a ton of refinements in these settings.
  9. If you want to adjust the window settings later they're found under Settings:Workspace:Window Management:Window Rules

Comment Seriously? Does the author use KDE? (Score 1) 111

You call this polished and mature? Never mind all the features that got tossed out and have to be rewritten. I use KDE all day every day and I love it, but this release is worse than Windows 10. My screen goes out of sync every time I leave the computer idle and plasma crashes several times an hour. By the way, wiping out all the activities and menu settings with the new platform was brilliant. That just made my day.

So you want a technological solution to solve a human-induced problem created by technology?

Yes, I do. Or rather I want to live in a community where people use all the tools available to protect themselves against threats to their safety. People have such an oversimplified understanding of how natural selection works. It's not only the individual who has to be strongest, it's the individual and it's family and it's community.

In the classic example of a lion pride we think of the male lion who has to be strong enough to procreate. We forget that for a lion pride to thrive it has to eat, and it's the female lion that does the hunting. The strongest pride isn't simply the one with the biggest male. The strongest pride survives drought, disease and myriad dangers. In order for the cubs to become strong adults they have to learn. They explore and test themselves. They make mistakes and survive to live another day.

Natural selection has prepared humans to climb trees to escape danger. It's prepared us to fight when necessary to protect ourselves and our families. Natural selection hasn't directly prepared us for all the noises and lights of the modern world. All it takes to snuff out life is glancing down at a cell phone and absent mindedly stepping off the curb into traffic. Humans don't thrive because we never make mistakes. Humans thrive because we use signals and systems to help us navigate a deadly world. If an app can alert us to danger that's just one more tool in our belt.

The school system had the kid arrested. They suspended him for three days and forced him to sign a statement under duress. They allowed the police to interrogate him, on school property, without legal representation or the presence of an adult guardian. You know what they never did?

Here's how I envision the gradual expansion of these technologies.

On the one hand we will have the open network; the public roads. Over the next two decades we'll see more and more automation integrated into our cars. Within 10 years we'll have the first vehicle-to-vehicle traffic negotiation devices show up. These will initially negotiate with the road signs, traffic signals and other vehicles. Within 20 years these devices will replace the signs and signals. The red light will be on our dashboard. The speed limit that currently shows on our GPS will have the force of law. At first the driver will be assisted by the automation technology. The computer will only take over when the driver is about to crash or run someone over.

Gradually the computer will take more and more of the driving role. It will park itself. It will brake at intersections. It will let off the brake when the light turns green (but the driver will press the gas to move forward). It will control the speed of the vehicle so the car can't go too fast. If an emergency vehicle approaches the car might pull off the road to let it pass.

In the meantime automation technologies will be integrated into private road and off-road networks. Golf carts will almost certainly be used in such a network. Standardization will allow industry to designate closed roads for moving goods between buildings and then within industrial parks. Then someone will want to connect the industrial park with the airport or seaport. Maybe they take a low use rail line and convert it to a closed road. Cities will probably close off downtown areas to non-automated traffic. People will hail a "cab" to get around downtown and use mass transit to travel outside the city.

As the technology advances the closed and open road systems will start to interact. You might drive to the airport but have your car drop you at the gate and then find a place to park itself. You go shopping and your car pulls up so you can load the groceries. In perhaps 30 years time the industrial system and the public system will be mature. Eventually we reach a tipping point where we just switch everything over to automated transportation.

I expect we'll do away with speed limits altogether. They will probably be replaced with an acceptable speed range. For example, where the speed limit is currently 55 the acceptable speed might be 50-60 mph. Once you integrate vehicle-to-vehicle communications this speed can change with conditions. The speed range on an icy interstate might be 40-50. That same section of highway might go to 70-80 when it's sunny and dry. http://www.autonews.com/articl...

The solution to this is already being discussed. It seems likely that in the future all cars will be equipt with vehicle-to-vehicle traffic control devices which will negotiate the right of way at intersections. The traffic signal will be on our dashboard. http://www.cnn.com/2015/01/14/...

It's called the "Emergency Stop Signal" and it's activated by ABS systems. It's required in some European countries. In the US automakers have to apply for special permission to use blinking flashers. Apparently the feature exists in many vehicles already but is disabled by software (and it's illegal to enable the feature in those vehicles). The NHTSA is still studying the issue and will probably have to modify their regulations. My guess is that it will eventually be required for all new vehicles.
