  1. Just a bunch of blocks? on Intel Unveils Optane SSD DC P4800X Drive That Can Act As Cache Or Storage (hothardware.com) · · Score: 1

    When are we going to get drives that are just a bunch of blocks so that we can do our own wear and use leveling? Why should I trust a tiny computer on the SSD when I've got one that can do far more on the other end of the SATA line?

  2. The last time I checked, a passenger was about $20 to $60 of fuel per hour of flight time on most jets.

    If the costs per square foot is considered, the cheap seats are seriously subsidizing business and 1st class.

    I think that adding 2 inches of pitch and width to the 1970s standard wouldn't effect prices very much at all considering how many other factors go into how much a seat costs on a route.

  3. I've seen something like this before on Quantum Computer Learns To 'See' Trees (sciencemag.org) · · Score: 1

    A friend was doing image processing work in the late 80s and managed to get some funding for image recognition test. The idea was an alarm camera could detect the family pet and ignore it but detect bad people and set off the alarm. The system was trained using photos of dogs. The end result was a program that could identify pictures of dogs. It was hopeless at detecting real dogs, but it was spot on about detecting pictures of dogs.

    Yes, pedestrians using phones running into other pedestrians is a real problem. Wrist and hip fractures are the common problems seen. A typical situation is a young fit person using a phone bumps into and elderly person who falls. There are also tram lines and an amazing number of people mange to trip over them over the last few years and most were using a phone at the time. I wonder if the jay walking laws need to have words like "or using a phone" added in the right places.

    I know the UK started trying to collect stats about these things after their NHS found out how much Pram Rage was costing them.

  6. How is that Traffic Calming working out? on UK: New Drivers Caught Using a Phone Will Lose Their License (bbc.com) · · Score: 1

    It seems that the number of distracted people hurt in distraction accidents is related to how much traffic calming used in the local area. Around here when they drop speed limits on roads with many shops from 60 km/hr to 40, the number of people jay walking increases and areas where there were a few near misses a year turn into a minor injuries per year.

    In the high traffic areas that are now pedestrian and tram only areas, the tram drivers are having far more emergency stops which can injure passengers. A nurse has told me that the number of people who are getting hurt in falls because they were run into by other pedestrians seems to keep going up.

  7. 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%.

  8. 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.

  9. Re:SCSI Voodoo on Ask Slashdot: What Are Some Things That Every Hacker Once Knew? (ibiblio.org) · · Score: 2

    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.

    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.

    I had that spec in a book that I threw out this month. It is amazing how much of the modern web look seems to have been out of the 1st edition of that book in the 1980s (if you ignore the function key stuff). At that time all the cool GUI work was done on the Amiga and later in NextStep.

  16. Re: Not so innocent after all on Humans, Not Climate Change, Wiped Out Australian Megafauna (phys.org) · · Score: 2

    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.

  17. 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.

  18. 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.

  19. 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.

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.

  23. The N64 wasn't ever fully used by developers on 'GoldenEye: Source' Updated: A Classic, Free Multiplayer Game (theverge.com) · · Score: 1

    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.

    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.

  25. Yeah, and what are they gonna do about it? File a complaint? bwahahaha

    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.
