Comment Re:The whole "blue light thing" is pure BS. (Score 1) 118

Humans don't need complete dark to sleep.
Some humans do need complete darkness to stay healthy. It turns out that people on common anti-cancer drugs who use night lights or have other sources of light 24 hrs a day have a much higher fatality rate than those who sleep in complete darkness for at least 2 hours a night.

There have been plenty of studies linking light pollution to melatonin levels and several types of cancer.

Based on numbers I've seen for Australia, light pollution is interfering with the one of the most common drugs used for breast cancer increasing the factuality rate by as much as 10%.

Comment The crypto is the easy part of this (Score 2) 196

The cryptography algorithms are the easy part. The vary hard part is protecting keys so I hope someone provides plenty of examples of how to do that properly. I hope they don't go down the Java route of showing how to use the functions without proper key management.

Comment Re:SCSI Voodoo (Score 2) 611

A real cool thing about a SCSI chain is that you could have several drives shared between several computers. A friend had an Amiga, Sun and PC all on the same bus with a few drives. There was even a program on the Amiga that could pretend to be a block SCSI device made up of parts of others disks.

I once ran a name server that would boot from a disk that was shared and maintained by another system. Named was run by init after the network setup stuff had run. The right signals on the serial line and bind would stop, remount the disk and reload its config thanks to a small program. That was when I started to like the idea of virtual servers that didn't have shells in them at all.

Work has more than 2 decades of experience supporting software products. The maintenance costs of Perl are far less than C which is less than c++ which is far less than C# which is far less than Python which is far less than Zope.

Zope has been the worst by far. We have hired 3 different people to rewrite a Zope app and import the data into a new system. The thing is the Zope app took about 2 weeks to write in the first place. 3 complete failures. The last time we needed a custom report for the system, it was a few minutes of work in SQL and Perl.

I've meet many people involved in getting men to the moon.

One was in charge of life support for the Mercury, Gemini and Apollo programs. Shortly before he died we had a long talk about Apollo 1. He was convinced that it was his fault that he didn't know that high O2 environment would have been highly flammable. There are likely a thousand guys who thought the same thing.

He also pointed out that USAF has a museum inside the Cape grounds and I should go see it.

There was some climate change occurring as a result of the widening gap between South America an Antartica at Tierra del Fuego. The increase in water flow of the Antarctic Circumpolar Current helps with the deforestation of Australia. There was a major event that widened the gap about 100,000 to 50,000 years ago which might have led to the migration to Australia. As the water flow increases, southern Australia will get drier.

Comment Security? (Score 1) 303

If physical security is an issue, do it right.

Around here they built a bunch of mini-police stations at every train station. They used metal studs about 6 inches apart in the "holding cell" part of building. That was covered inside and out with 7.5 mm cement sheeting and they seem to use a stock steel door. They don't have to worry about windows but I would go with a triple glazed or put bars over them but don't make it obvious so maybe like a sun shade or inside. I use protec locks because they are very good locks and they are somewhat unique.

Put that cat6 in a duct and do something about the ground isolation. I would be tempted to move the fibre to the new building and then just use wireless back to the house. A rack means rack mount equipment and that stuff tends to be noisy so it needs to be in a different room and you need to have an insulated wall between them and I would be tempted to build it as an isolated sound wall and in your case, maybe its own exterior door just to keep the office quiet. A modern 19 inch server rack is 600 mm x 1200 mm and needs 1200 mm in front and 600 behind or else you can't slide servers into it or work on it. Access on the side is good. For small computer rooms I do like raised floors but you must make sure the tiles are the same as your rack (so no metric tiles for a two foot rack). Also builders finish floors by cutting tiles to fit the room. In a small computer room, you must make sure the walls are the right size and builders don't like building walls to interior dimensions. If your rack is too tall, you might not be able to get it in the room.

Split air conditioners work great but if you have two rooms, you need two of them and a way to deal with a failure if you have to run the computer 24x7. The smaller ones are more efficient than the larger ones. Figure where the water will go when the A/C drain backs up.

Put in a large electrical panel. More circuit breakers mean you can have stuff fail without taking out everything else. You don't want a cheap USB charger taking out a server.

This happens to be in the state of Victoria in Australia but other states here also have strong consumer protection laws that basically say you can't be selling an unfixable product at a premium and not support it. The same is true for much of Europe as well and the few US states that haven't battered down their consumer protection laws.

I own a few Mac mini (Early 2009) and once they are no longer supported by Apple, they are subject to a full refund should they fail under the local state laws. There have been many rulings involving full refunds for non-supported white goods with one example of a $400 washing machine failing a few years after the warranty with no ability to repair it and the ruling said something along the lines that "the device was expansive and people expect it to last much longer than the warranty period" with ordered a full refund. Similar cases have resulted in orders for a new product to replace the old unsupported one. Since the current Mac mini is slower than some of the older ones and cost over $1,000 with reasonable memory, I can't see Apple winning let alone arguing that it is "obsolete" or "vintage".

I've spent much of the last two decades dealing with people who are attempting to correctly deal with money. Float problems show up all the time. For the longest time all CPUs had BCD arithmetic but modern CPUs are getting away from having any but the most basic instructions and sometimes they are suboptimal and use far more cycles than they should.

I think the largest missing feature of Go is the lack of a true currency type. The lack of that type means that every program that copes with money in any complex way has a very high probability of being very slightly wrong in some small number of cases.

Comment Re:Where exactly was the bug... (Score 1) 88

Until older machines (like the millions of 32 bit intel and PPC macs) get fixed, the ethical solution didn't happen. Is Google big enough to force Apple to fix those? If you think the recent IoT bot net was bad, just wait for those million of older macs get p0wned. The unsupported old macs don't get thrown away, they get handed down and they are still out there on the net waiting to cause problems. The software update option appears to still work even on my old mac mini g4 that wants to update printer drivers every few months undoubtedly leading many people into a false sense of security.

In most of the EU, some US states, and most of the Commonwealth countries, a manufacture is required to repair defects indefinitely that are likely to cause harm to others.
