But despite its double life on x86 and ARM processors

I think you forgot the PowerPC there, hoss.

And if you're thinking ARM, think ARM6 for iPhone2G-3G, ARM7 for iPhone 3Gs-iPhone 5, ARM8/AARCH64 for iPhone 5S+. NextSTEP and OpenSTEP were also available for M68k (as used by Next), SPARC & PA-RISC.

I was always curious on the "secret double life" aspect of MacOS X. How was it a secret when you could always download Darwin x86 from the Apple Website. It was MacOS X without the Window Server and the Graphical Applications. Same kernel, mostly the same libraries and daemons, different set of applications.

That is one of the most interesting usage scenarios. While a complex operation, you can upgrade the RAM on a MacBook by changing the BGA RAM chips and moving the RAMCFG resistors to a new configuration, but the on-board SSD is not upgradable since the controller can encrypts the NAND, including some of the vital information. Being able to swap the NAND to larger chips and reinitializing it in the T2 would open up some possibilities.

Good luck competing against BlackBerry's QNX which is currently installed in over 50% of all vehicles produced today. Yes THAT BlackBerry.

Those statistics are terribly out of date.Most current generation headunits are converging towards GenIVI/AGL based Linux. The other modules (PCM, BCM, RCM, etc.) don't actually run an OS in most cases as they are microcontrollers.
VWs actual problem is caused by the 10km of wiring found in a car and by the lack of standardisation across the industry. CAN as a bus is standardised, but the messages sent across it are not standardised even across the same generation of products from the same vendor. Obviously, that means that they require special software builds and testing for each vehicle, locale, etc.
Tesla is making interesting changes to this architecture in the near future in order to simplify the wiring in a car.
I've recently "ported" a Mazda CMU entertainment system to a mid 2000s Subaru Forester SG. The wiring sheet *SPECIFICALLY* for the CMU multimedia system was printed on 5 A3 pages glued together. The new generation CMU from Mazda is a bit more interesting as it is a bit more modular with components shared with other Japanese brands. Right now Subaru is the only one still using QNX, but they are switching to AGL as well.

Experimental Device Generates Electricity From the Coldness of the Universe (phys.org) 129

An anonymous reader quotes a report from Phys.Org: An international team of scientists has demonstrated for the first time that it is possible to generate a measurable amount of electricity in a diode directly from the coldness of the universe. The infrared semiconductor device faces the sky and uses the temperature difference between Earth and space to produce the electricity. In contrast to leveraging incoming energy as a normal solar cell would, the negative illumination effect allows electrical energy to be harvested as heat leaves a surface. Today's technology, though, does not capture energy over these negative temperature differences as efficiently. By pointing their device toward space, whose temperature approaches mere degrees from absolute zero, the group was able to find a great enough temperature difference to generate power through an early design.

The group found that their negative illumination diode generated about 64 nanowatts per square meter, a tiny amount of electricity, but an important proof of concept, that the authors can improve on by enhancing the quantum optoelectronic properties of the materials they use. Calculations made after the diode created electricity showed that, when atmospheric effects are taken into consideration, the current device can theoretically generate almost 4 watts per square meter, roughly one million times what the group's device generated and enough to help power machinery that is required to run at night. By comparison, today's solar panels generate 100 to 200 watts per square meter.
The study has been published in the journal Applied Physics Letters.

Battery technology should be making a leap pretty soon. But I'm not familiar with the time scales of these sorts of advancements: https://www.futurity.org/ceram...

Hopefully the technology will become available in consumer devices at a point when it still has the power to impress us with a charge that can last a few days.

Among some of my clients, I administer the UNIX infrastructure of a small Telecom operator. They have about 100 Linux Servers running RHEL, JBoss EAP, FreeIPA, CloudForms, Satellite, etc. This costs about €40k/year. The alternative from Oracle would have been €500k with their incredibly bad support.

I remember being excited when Oracle bought Sun. SUNW was running out of cash, but they had a spectacularly good software portfolio with ZFS, DTrace, Comstar, etc. It all went bust. Solaris hasn't seen any innovation in 10 years.

Suddenly SuXE is starting to look good again.

Comment Economic Difference (Score 1) 171

If there's no economic advantage to recycling over dumping, maybe recycling isn't worth it. Ideally you'd be able to tell that recycling is actually happening because it'd be cheaper than dumping. Of course I'm ignoring the environmental impact. If that's the only benefit of recycling, I fear we're doing something wrong.

Comment You can make it boot in less than 1 minute (Score 1) 253

All you need is to compile your own kernel without useless stuff such as ACPI, PCI, USB, SCSI, MD. This is a config that should work like a charm for that system in at most 3 seconds (instead of 14) on a 386sx PS/1 and with a lot less RAM based on 2.4.37.11. You only need SB32, VESA, EL3 (3COM), TTY, ISA, ISAPNP, PARPORT on the hardware side. It also has support for SMBFS. It can further be trimmed without SMBFS and NLS to around 600kb (loading and decompressing are slow on a 386.

Comment The '93 ps/1s were easy (Score 1) 253

The post '92 PS/1s were easy because they behaved like an AT system, but the '92 ones were a bit more difficult. I've done the same thing on a 2133-W13. It was a complicated PS/1 because linux's setup.s couldn't detect the IDE drives. It incorrectly assumed that the FDPT is at 0x41 and 0x46 and the HDD type is at 0x19 in CMOS. While that is true for the AT systems, the PS/1 systems were not AT. IBM released a unixboot.com binary that can solve this for a single boot. With a bit of hexediting to kill the final reboot you can put it as a syslinux .com executable to use as a preload to the Linux Kernel.

You can obviously solve this by adding ide0=0x1f0,0x3f6,14 ide1=0x170,0x376,15 hda=3884,16,63 hda=noprobe hdc=cdrom, but there are still some issues.
