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.

Comment The N64 wasn't ever fully used by developers (Score 1) 65

It turns out that the only thing fully made use of the power of the GPU in the N64 was the spinning N at the start of the games. The main CPU loaded up the GPU with some data and then went to sleep for a few seconds while the GPU did all the work. The 3d libraries did make some use of the chip but most of the work was all done in the MIPS CPU.

I wonder if the GPU wasn't used as result of programmers not having any idea how to use it or if using it would make games impossible to move to other platforms.

Comment Re:Stop using OS X and their 10 year old computers (Score 1) 472

I have an aged iMac that has a wonderful true 24 bit display but a bad bios so I can't boot the new stuff. I'm tempted to take it back to the vendor and demand a refund as the only reason it isn't useful is because Apple won't provide an update. The thing works great as a hackintosh so it can run the new software without fail.

Apple made its best code when it also supported the PPC. They had to build things for two majorly different systems and that found lots of bugs early in development. Remember OS X started in 386land and moved to PPC and then back to Intel as it moved from NeXT to Apple. Oddly enough there are people who register performance ratings and have seen modern IBM power CPU running OS X that far out run the current Intel stuff. It sort of sucks that Apple stopped selling top of the line CPUs because of a golf game.

If they are smart, they will talk to their local representatives and say "Not only is Microsoft not paying its fair share of local taxes, they are being anti-competitive."

Many countries make the practice of only offering some products to a limited number of large companies illegal. If those products can provide an economic advantage, the discrimination against smaller companies is illegal and subject to heavy fines.

The movies I enjoy in a real theater tend to be very bad movies. I sometimes go to the Astor in Melbourne and their current calendar has Mothra, The Thing, and Videodrome. They are running a double feature with Wrath of Kahn and Beyond where I expect the audience will be more interesting than what is on the screen. They also do good movies but I'm less likely to go to them but their screening of the Shine might be interesting since there will be a Q&A session with the producer, director and screen writer. The place sells beer and has strict no talking policies for most movies. They also do sing alongs like Meaning of Life and Rocky Horror.

Retirement funds are buying most of the tech stocks. Some of them have the problem that they have another billion dollars every week that they have to invest in tech stocks and there just aren't that many good investments so they dump it into well know tech players. It is even worse in the UK where one type of high growth fund only allows investments into 200 companies that are registered in some government scheme. Some of their stock prices seems to have nothing to do with any type of value.

Richard Feynman wrote in the introduction of one his books that one easy way to find out of a theory is bad is to look at its complexity If it isn't simple, it is most likely wrong. He went on to talk about how strange the orbital mechanisms and mathematics were before Kepler found the correct and simple solution to the problem that disproved nearly everyone in the field. With that he ends the introduction and delves into quantum mechanics.
