Comment Re:Or just make the diesels hybrids (Score 1) 166

Depends on where in the world you are, but diesel locomotives usually have a generator that produces electricity to electric motors for traction. It allows for a smoother transition of power since the electric converters acts as a gearbox. In western Europe most trains are electric but on some tracks there's no overhead lines and then the diesel-electric locomotives are used.

A hybrid is essentially just having both overhead lines and diesel engine/generators to feed the traction engines.

However when it comes to overhead electric lines there are a large number of variants ranging from 16kV 16 2/3 Hz to 25kV DC and in between variants with 50Hz as well.

Comment Re:Hydro = from the sun (Score 1) 130

Considering that solar collectors are requiring quite some resources to manufacture - some of the material is in limited supply - it's looking good on paper but in reality it's not that easy.

A medium sized water power turbine can produce over 100MW while a solar panel can give at best 1kW/m2 given ideal conditions. That means that you need at least 100 000 m2 (24 acres) of solar panels to produce the same power.

So solar panels may be a nice add-on to power production but it won't be a cost effective production for the bulk production.

Fission elements doesn't come from the center of the sun, at least not the current sun we have. And fission energy looks nice on paper but is actually pretty expensive - and emits CO2 due to mining, refining and building of power plants.

Direct solar may sound nice and work fine in small scale, but collectors would have to cover great areas to be effective. Hydroelectric power is concentrating the power to areas in a more effective way. There are of course disadvantages with hydroelectric as well, but the impact from the alternatives is often worse.

Submission + - Free Pascal Compiler 3.0.0 is out, adds support for 16 bit MS-DOS and 64 bit iOS ( 1

Halo1 writes: Twenty-three years ago, development started on the first version of the Turbo Pascal and later also Delphi-compatible Free Pascal Compiler, for OS/2 no less. Two decades and change later, the new Free Pascal Compiler 3.0.0 release still supports OS/2, along with a host of older and newer platforms ranging from MS-DOS on an 8086 to the latest Linux and iOS running on AArch64. On the language front, the new features include support for type helpers, codepage-aware strings and a utility to automatically generate JNI bridges for Pascal code. In the mean time, development on the next versions continues, with support for generic functions, an optional LLVM code generator backend and full support for ISO and Extended Pascal progressing well.

Submission + - Windows Phone hacked! Unlock bootloader, get root, flash custom ROM (

BrianFagioli writes: Windows Phone and Windows 10 Mobile are probably the last operating systems you would expect to be hacker-friendly. After all, despite its occasional embrace of open source, Microsoft is largely a closed company. Today, this perception could begin to change, you see, as a new tool rocks the mobile community. Called "Windows Phone Internals", it allows Lumia owners to unlock their bootloaders, gain root access and even flash custom ROMs. Whoa.

No, you are definitely wrong. Systemd is only sold into the larger distros and forced down on sysadmins all over the world. Not unlike how Windows was pushed.

Systemd != Linux and Linux != Systemd.

Systemd is very much like a prison that locks up users into a closed community. Very much like Windows.

Neutrinos have bad breadth.
