Comment Re:Data rate or transmission delay? (Score 1) 59

I'm guessing that the throughput is slow enough that sending a command to the spacecraft takes 20 seconds of tx time - e.g. it might take 10 bytes to send a command and are getting a data rate of 4 bits per second.

Latency isn't as much of an issue in this case, as once they send the wake up command, they can have the other commands in flight on their way to the satellite, but it's going to stop listening and do something they don't want it to do ~2 minutes after it gets the wakeup command - likely due to a fault with a sleep timer or similar.

Comment Re:The problem with FreeDOS... (Score 4, Insightful) 211

Have an old legacy proprietary DOS program that you need for your business? Then throw it into /dev/null, and hire some talented programmers to write a modern free open-source replacement for GNU/Linux, that will get published on github.

Why, that just sounds like an absolutely wonderful idea. Why would anyone insist keeping on using some old software that has been paid for many moons ago, and we all by now know exactly where and when it does and doesn't work because it's been doing the same task for 20 years? Why not instead pay thousands and thousands of dollars for someone to attempt to write a replacement for it, possibly reverse-engineering a proprietary and undocumented hardware interface (costing thousands and thousands of dollars more more in time) only to give it all away to the handful of other people on the planet who also use the same version of WHATEVER.EXE that I'm using?

Yep, what a smashing idea!

Modern drives will silently remap sectors without telling you (unless you look at the SMART status).
Once they exhaust their pool of spare sectors, then they start telling things higher up the chain that there are bad sectors.
By the time a disk is reporting bad sectors to the OS (as a bad sector, instead of incrementing a SMART counter and silently carrying on) it has remapped so many bad sectors that it can no longer automatically remap them and is now telling you there is a problem.

In my experience, every single drive that I've seen reporting even a single bad sector will soon go pear-shaped and shouldn't be used.

Yeah, but then you can't accurately know the cost of de-duplication, additionally you're doing work against already committed files which is a big no-no if you want stable storage. If I commit a file, I don't want a background process to read/write it and a software bug to screw it up years down the road.

Additionally, you're taking away resources from a system that will already be taxed. My file server has a load of 1.2-2.5 on an average day (because I'm running against the IOPS limits on my 5-year old SSD's), doing ANYTHING (even streaming a backup) has to be meticulously planned so as not to affect the system.

Wow, what are you doing on your server that you're thrashing your SSDs with 500+ IOPS 24/7?

You have inordinately cheap disk

Because of Apple's tendency to solder the SSD to the mainboard in the Mac Pro and all current MacBook laptops other than the non-Retina MBP, an upgrade requires replacing the whole computer at a substantial cost. Only external storage is "inordinately cheap" on a Mac, and not all laptop use cases make external spinning rust practical.

I don't know what Mac Pro you're looking at that has the SSD soldered to the mainboard, but in the one on my desk, the SSD is a PCIe interface that's plugged into a socket on the back of one of the graphics cards. There are even third party replacements for them: https://eshop.macsales.com/sho...

Sure, you could find lots of value in compression.... and you can get it with file compression utilities.

That's fine, so long as these utilities can let the user mount an archive read-only as a folder and thereby let other applications see the archive's contents as files in as a folder. Does macOS Sierra introduce anything that interferes with OSXFUSE?

You mean like creating a compressed .dmg disk image (a capability that's existed all the way back to 10.0.0) that (by default) is mounted in /Volumes/[disk name] but from the Terminal can be mounted anywhere you like?

Comment Re:Sierra with Siri (Score 1) 249

Exactly.
On one side of the camp we have Mac OS X (and later just OS X) 10.0, 10.1, 10.2, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8, 10.9, 10.10 & 10.11 with minor updates coming out at 10.x.x
On the other side of the camp we have Windows 95, Me, 2000, XP, Vista, 7, 8, 8.1, 10 with some of them receiving service packs, some receiving rollups and some getting service releases.
