    I doubt you understand what social justice even means. It means that justice should be defined by the zeitgeist of the "social studies" departments at colleges/universities instead of existing laws and regulations. This issue IS defined by laws and regulations which the government is trying to skirt around.

    Although I understand the comment is a bit of a quip, even if you trusted the government or don't mind the government has access to it (eg the key is for a government agency), you can be sure the government won't be able to retrieve it when either you or they need it.

    This is the thing with the iPhone the FBI is trying to crack - the government did have the key and was even capable of changing the key remotely because they owned the phone but couldn't be bothered to keep track of the new key. The NSA has the same problem, they have data on trillions of phone calls but don't know how to find, sort or filter it. There was a story they even asked Google to help them.

    Interact with any government agency and they all have the same problem, my kids SSN letter got lost in the mail, even with all the evidence that we were the parents and when and where the kid was born, birth certificate etc, the office couldn't retrieve the newly generated SSN and it took them ~3 weeks for their "systems to process and synchronize" (which was already ~3m after the original SSN was sent to us)

    Not sure what you mean by eliminating insects and reptiles, afaik none of those are endangered. The problem with killing large animals like orcas, sharks, lions, elephants etc are that those are very impactful on local ecosystems. You kill 1 lion or 1 whale and suddenly you have an entire family in trouble and that has an immediate impact on other species in the area and the entire system goes out of balance. You kill a bug and there will be millions more to do their job and we typically only kill bugs/reptiles that overpopulated and threaten "our" ecosystem of food production or that threaten existing ecosystems that have gotten out of balance (such as invasive non-native species).

    The problem in a lot of other countries (not sure about Ireland) is that they are even less protected than the US. Even though we're chipping away at it, the US has somewhat decent protections against government overreach and if this goes to the Supreme Court (which it seems like it will), they should reaffirm those protections. In England the crown could just tell Apple to give them the keys/code and there is little to no legal recourse.

    The thing is that most federal agencies require "public" data sharing for any grants >500k. The reality is that nobody does it.

  7. It's kind of important to know whether or not windows are possible at all in these things before you build them. Some issues I might see is the weight of the windows or the issues when the windows fail (either by inherent forces of the system or internal/external damage (bird strike, crazy person)). Also it might be important to know what the physiological reactions of your passengers will be if they zoom by the countryside at Mach 1 (or eventually higher) speeds, I think motion sickness may be a big issue if you can look out the window but your eyes can't lock onto an object, so why bother with windows if half of your passengers puke with them, and how many people can or like sitting in a tin can for hours without any either real or simulated windows? How heavy will those displays be and their power requirements and what do we need to show so people still have a sense of location and time.

  8. Set up a kickstarter on Ask Slashdot: Alternatives To "Atomic" Clocks? · · Score: 1

    The reason these things are expensive is because it's neither cheap nor easy to "just" implement something with WiFi-to-NTP. You need some sort of an interface to enter WiFi settings, you almost need an entire OS with a DHCP daemon, TCP stack, NTP daemon, you need the WiFi chip and be able to power it (you would hope) using a battery for ~1y. Then you also need a way to fix your clock either using a stepper motor or some sort of time stretching mechanism (where you ignore or add a number of ticks until you have 'corrected' the thing). Then you have to go through FCC regulations because you're creating a transmitter and that will set you back a few $1000's and months of engineering time. That's your entry cost without any ongoing 'tech support' you have to have live for people that can't figure out the thing, security updates (as if) and time zone and daylight savings management/updates.

    That's a LOT to get done, even if you boot for a few minutes every 24h to sync the time (and what if you don't have a WiFi signal right then and there) and your market for that tech will be relatively low; most people don't mind spending 1 minute every few months fixing their $5-25 clock, having them spend more money only to get the privilege of changing their battery just as often as they need to change the time is not worth it, the product is dead before you even have it marketed.

    If you need such accurate clock, they do exist, they are expensive because the people that need them neither see the direct cost nor have the objection to pay thousands for an accurate clock. The other 'markets' are so niche they already have custom products that don't rely on buggy WiFi/TCP/OS implementations.

    GPS has similar cost problems as far as the tech goes, it takes too long to lock onto the required GPS satellites especially indoors where it just becomes a very expensive broken clock.

    But doing it like that requires significant investment in extra wiring and zoning ordinances which depending on your electric code may not necessarily be either easy or cheap to implement/retrofit. Retrofitting some COTS "smart" switches on an Android would cost ~500-1000/room including labor, running new electric will cost at least 5-10x as much.

  11. I just don't see where it makes sense, even for Microsoft; disabling an activation key because they found it on Google should be trivial for them. Even if they somehow got all the ISP's in the world to do their job, it still is more work to notify ISP's and wait for their cooperation than simply clicking a check box in a database.

  12. Not all of them but at least they would know which entity holds a particular key and they could (and do) limit it to a particular IP range.

    I understand the potential in shared hosting and it's good as long as you stay under a certain amount of scale. For most small business, shared hosting is great because you don't have to buy into an IT guy but can just rent Google or Microsoft to do it and until you spend more than having your local IT guy do it, it makes some sense.

    However in most large companies and Universities especially, most of that scale is gone because a University (super computers, workstations, smaller clusters etc) requires PB's of storage to be semi-locally hosted. So you'll spend $100k/month on something you could easily have had by leveraging your existing investments for a little bit of document storage yet the requirements to have people supporting said cloud locally doesn't magically go away. Maybe your second level support staff can be slightly cheaper as you're offloading some of that (except you're still responsible for deploying, supporting and managing said solution) but you still need the same expensive talent not just managing your local datacenter but also managing your 'cloud' infrastructure so you need even more expensive talent and products and vendors to tie them together.

    If you can't see the problems both in cost and performance with shared hosting, you're probably not very good at your job.

    Whether it's called cloud or saas or iaas or shared hosting, it's all the same; you can't abstract certain problems away, if you're spending more on "vendors" locally than you would having the same "vendors" doing it remotely with the overhead of internet connections, 3rd party data centers and profits you're bad at either knowing what you need or knowing what you're getting.

    This University bloke is most likely unaware of the 100s of TB of data that are amassing in local department server closets. Not because cloud isn't available but because it just doesn't work.

    Transversing metadata is not my primary concern. It only happens once every few months when someone forgot where they put their files and it's usually deductible in other ways.

    The only solution for that is actual block level backups. This requires file system support to be able to snapshot and/or indicate blocks that have changed. It still takes a week or so to take the initial backup but after that, you could take a snapshot every 5m and replicate just the changes across multiple volumes. If your ingress of data exceeds your capacity of egress to a backup however, then you need to rethink your architecture.

    I have a system that can take hours just to transverse and read the metadata of each file (doing a find or ls) with multiple volumes. Reading the entire dataset to dev null takes 72 hours. Snapshots every 15m complete in under 1m although the initial block level backup takes ~2 weeks over gigabit.
