Celsius is too imprecise compared to fahrenheit. To get the same precision you have to resort to fractions which is annoying when speaking or programming thermostats.
Celsius may be more standardizable but fahrenheit was designed to accomodate people rather than state transitions of water.
All of the other measures I have no opinion about. I think we should all at least have a rough idea of the scale and conversions between systems.
"I've heard we have been running out of IPs for years now and it never happened so I don't believe you now."
But when did they say we would run out? It was never tomorrow or the next day..a decade ago the predictions were always sometime in the next decade.
"ISPs benefit from selling IPs to consumers or selling off unused blocks in the exchange"
Except for all the ISPs who have no more addresses to hand out and now must purchase large expensive boxes to keep connection state for protocols..(or buy IPs at ripoff rates from third parties). Routers that can forward packets via an ASIC at wire speed are expensive enough. What happens when they also have to understand the content of data at much higher levels using general purpose processors? What about CALEA compliance hell caused by no longer being able to associate addresses with users without long term storage of massive amounts of state? What about commercial web sites that need an IP for an SSL site or a colo facility or a large business customer? Yea you might be able to make a few dollars more from selling static IPs to the few people who ask for them but in the bigger picture IPv4 shortages suck for operators.
"IPv6 adoption is a failure and will never happen"
Companies who in total are responsible for more than half of total US bandwidth utiliziation will be posting AAAA records on IPv6 day AND the largest ISPs in the US all have active trials. IPv6 is uptake is currently following an exponential curve.
After being forced to think unflattering things about google in recent months search changes and the ever useful "block all results from this annoying site" is starting to make me like google again.
For the love of god they still need to get rid of live preview or just make it such that accidential sneezes don't always trigger it.
Forcing people to do something they may not care about in the name of national pride I think is quite dubious on moral grounds.

South korea is known internationally for their starcraft prowess should they force everyone to play starcraft for 2 hours a day to ensure continuance of their world dominance?
The problem with federated trust used in this way is that it does not give the end user any confidence they are communicating with the party they think they are.
Yea great so you can use the same credentials to login everywhere... Except what happens when a malicious site masquerading as your favorite online store starts accepting open id credentials?
All of the current federated systems as deployed right now rely on SSL CAs to establish trust.. They don't actually solve any security problems in their own right or address any of the core trust issues surrounding CAs.
I know history says that Jesse is wrong. The past is littered with all those who have come before having made the same predictions only to be consistantly proven wrong by history while global living standards for all continue to rise.
However I still wonder if at some point in the future as machine intelligence improves the whole system won't come crashing down.
A world where unskilled labor has no hope of employment I would not be in favor of within the context of the current system.
Globalization is responsible for all kinds of imbalances and disruptions throughout the world. I'm not so sure people who take a stand against them or seek to mitigate these problems should simply be cast aside as holding back the future. It is possible to have your cake and eat it too. To make forward progress while minimizing the side effects of globalization.
You are mistaken. For example as an evangelist this guy may know who Microsoft's weakest clients are, those most receptive to a pitch from Salesforce. He may even know their specific concerns and use such insider knowledge in his pitch
I am not a lawyer but I hope the Minority report concept has no root in the legal system of this country. To make a decision based on the concept someone *may* in the future decide to use privledged information in violation their contract as a pretext to constrain their opportunities is fundementally unfair and illogical in my view.
I hope the judges decision had nothing to do with hypothetical possibilities.
Installed IE9..saw there was no way to configure a separate search bar or disable blurry type and uninstalled it after 10 minutes.
IE10 may be a good browser in its own right but with millions still on XP and Vista they are basically forcing those users to other browsers while pissing off content developers in the process.
The future of semantic web will be in the form of intelligent agents that understand language and auto parameterize information. Expecting humans to willingly take the time and effort to do it themselves to their source data manually is not realistic and a waste of time because it may not be known in advance the best way to organize for all consumers.
Besides there is no commercial incentive. Most of the Internet is run by money with a direct financial incentive to push their own crappy UI and nest of ads upon all who seek their information.
I actually enable individual users to share their data, creating crowd-sourced systems.
1. Individual users have and will continue to have real IP addresses. Their toasters and refrigerators do not. Single IP address is sufficient for peer to peer communication, as countless products (that actually work) had shown.
No, absoultely incorrect. Out of IPs means OUT OF IPs... It means in some part of the world you may not even see a single address to run any servers of any kind... What you will get is a shared IP on a CGN with all incoming requests silently discarded by the ISP CGN... This will be reality for countless millions in the developing world in the next few years.
I'm being serious here with this question: Why do people feel that EVERY new device needs a public address? 99.9% of mobile devices would be quite happy behind NAT. And, the vast majority of 'home' PC's would work behind NAT. Most corporate LANs are also sitting safely behind them.
Sure there are some exceptions, but most people really don't need unrestricted incoming connections.
Is wider use of NAT the 'answer'? Perhaps not, but it would extend use of v4 for decades..
When there are no more IPv4 addresses...there are no more addresses. At that point it is less about making sure every device has its own address and more about would you even get a single address for all your devices? Maybe this will never be an issue in your country but in the developing world it is a real concern.
NAT means end users can't all have the same opportunity to run their own servers or participate equally in peer2peer file sharing, voice (skype)..etc.
Again this won't effect *you* any time soon as a value judgement I would rather see the world move to an addressing system that ensures everyone on the planet equal access. You may not care or agree.. that is your right...
I hope to in decades IPv4 will have been relegated to history.
What freaks me out the most about new homes is the switch from copper to plastic for water pipeing.
Regardless of baseless speculation of TFA..wired ethernet = less latency, better reliability, more bandwidth, less headaches and no driveby/neighbor issues... If it is a new home take some time to string some cat5 before the drywall goes up.. You can get 1000' rolls of the stuff for less than $70 online. Nothing to loose.
Nobody wants video conferencing... Heck people don't even want to *speak* to each other. There is no mass market in it...EVER... Every company who tries fails...
And people are not stupid... if they want video conferencing they'll buy a $60 web cam and use skype or MSN for free...
The mass market will NOT accept hundreds of dollars on hardware and recurring fees to use a service that does not need to exist on top of that.
No, this is incorrect. Both the kinematic time dilation and the gravitational time dilation are extremely small, but they are roughly on the same order of magnitude in many situations in ordinary life. E.g., if you're flying on a passenger jet, the size of the two effects differs by less than a factor of 10. Also, it's not acceleration that determines your gravitational time dilation, it's gravitational potential
FWIW the contribution of gravity is the same as the escape velocity.. on the surface of earth it is about ~7miles/sec.
Wouldn't this "gain" depend on which direction you're walking - along with the rotation of the earth, or against it?
Assuming both people are on earth it would NOT matter which direction realitive to the other or rotation of the earth they were moving. If they were going 100 mph twoard you or 100 mph away from you the effect is exactly the same.
However there is a problem in that the person who gets in their cars or starts walking their realitive velocity is the one in the accelerated frame realitive to the person standing still. So references only work against fixed features like Micro$ft HQ unless both people run the app and the system is able to account for compensating deltas on both sides.
There is another problem in that gravity has the same time dialation effect. Difference in gravity strength with altitude or distribution due to land features realitive to the other person or thing being referenced also matter.
Or if you're comparing to non-earthly reference points - along with the revolution around the sun & galaxy or against them?
Yes, absolutely and it would need to account for their gravity wells.. without having seen the app I'm guessing it was only intended for reference on earth.
Every SSL web site I care about requires me to login. Why not just make mutual password knowledge part of the SSL handshake and be done with it? Then even if a TLA or someone from a convention in vegas decides to take over the world at least the billions of people who have already established trust won't have to worry.
There is still a problem of initial trust when establishing an account but by punting that to the edge people would be better able to make their own decisions. Is SSL good enough? Or would they for example require me to show up in person with ID when setting up an online bank account?
The real issue with the use of DNSSEC is that CAs verify "who" you are...Not "what" domain you have..in practice I'm not sure anyone cares about that. Such a scheme would theoretically be easier to register a typo domain name close enough to a bank to scrape a steady stream of credentials from unsuspecting victims.
Modern commercial RDBMS systems have extremely complex intelligence to manage execution cost including self optimization cost, concurrency, partitioning, escalation, versioning, distributions, index selection, data caches, auto parallelization..etc.
When I see people talking about alternatives be it object stores, key/value, log...etc I ask where is the intelligence... Where is the billions spent on R&D in these new systems? They all appear dumb imitations that always ask you to sacrifice something..be it consistancy, concurrency, model restrictions or for a human to exactly define semantics or access patterns to enable a specific solution.
Is there really a way to create a new **general purpose** data system at least as powerful and useful as the RDBMS without spending on the order of a billion dollars on optimizer design?
For some applications csv flat files run circles around the RDBMS... In the general case flat files suck.
I believe generally the same applies across the board. Yes given a specific problem you can provide a specific solution that is faster better cheaper however the shortcut would not enjoy general applicability.
It's a language, not a data model or representation. In addition, the server sits at the end of a socket and acts like it's an interactive terminal session, using a human-friendly language, one command at a time. This means for instance that the server has to perform queries in the order issued on any one connection, but there is no guaranteed order or way to state dependencies over multiple connections. As opposed to say having a single connection with a protocol (not some chatty terminal session), asynchronous,
All SQL databases I work with have asynchronous wire protocols allowing multiple concurrent execution within a single connection/transaction. Maybe you should upgrade?
...is that SQL sucks as a language. It's not terribly expressive, the ordering of arguments is inconsistent, and whoever designed the way JOIN works should be in jail.
Frankly, I'd like to see SQL die and get replaced with something more modern. We don't program in Cobol anymore, so why the hell are we still using SQL?
If a scientist tells you something you don't like or you want more information about it can learn and get more information it if you care enough about the subject. If it becomes too hard for you...boo hoo..
If the bible tells you the earth was created in a week you can't well ask god for clarification of what he meant.
TFAs tour thru the ideas of trust and authority is not particularly insightful or useful.

Then you wouldn't need to deal with all of the laser measurement problems..

At 10% effeciency I'm not understanding the appeal.

You can get about 30% effeciency today by pointing concentrated solar energy at a stirling engine.
The effect itself is more intersting to me than the possible use in solar energy.
