Why are the poles of a magnet located inside and not towards the edges?
The dirty little secret is that there aren't actual poles on the inside either. A pole implies a point that magnetic field lines emerge from or disappear into from all directions. But it turns out that magnetic field doesn't work that way. Rather the magnetic field on the inside of a bar magnet is like that inside a solenoid:This is in contrast to an electric dipole, which really does have two poles inside:
How is Anycast implemented using IPv4?
As Tony said, anycast is quite simply the practice of numbering multiple hosts with the same IP address (usually in multiple geographic areas), then advertising a route for the IP from each location where there is a host. Traffic to that address will then terminate on the host that is logically closest, in terms of IP routing metrics, to the sender, improving reply latency.The big problem with anycast is that within the scope of a single transaction, all traffic must go to the same end host on both ends. When you have multiple hosts responding to the same IP address, there's no guarantee that a change in routing metrics won't change which host traffic goes to in the middle of your session or transaction, which will cause the communication to fail.As such, applications that work best via anycast have traditionally been single-query/single-response UDP transactions such as DNS resolution. TCP-based protocols are more fragile going to anycasted endpoints, but depending on the use case, that can be an acceptable risk. The fewer packets and time involved in completing the transaction, the lower the risk. Long-lived transactions, on the other hand, are usually a non-starter for anycasted endpoints.The best strategy I've seen is to use an anycasted IP for a DNS resolver that responds to queries with unique host IPs that are in the same location/site. That gets you the benefit of users being able to "find" the closest endpoint, but ensures that all transactions will complete.

Can titration be used to determine the acidity of dark balsamic vinegar?
Yes it can, but it is a little tougher than white vinegar. In order to determine the endpoint of a titration you generally use a chemical indicator, which changes colour at specific pH's. The problem with this approach is that dark balsamic vinegar makes a colour change difficult to spot. Some possible solutions for getting around this problem would be: either dilute the vinegar solution in enough water to allow the colour change to be seen; or use an electrical titration device to determine the endpoint, thus bypassing the colour issue altogether.
Is Mediafire.com safe to download from?
there is a file that I can't get anywhere else on the internet and I have never heard of mediafire so I was wondering if it is a safe place with no viruses or anything

Why is VMWare Airwatch the best option for enterprise mobility security solution?
'Best' is a loaded word. Enterprise Mobility Management is fast developing into a critical tool for organizations adopting mobility. But each organization comes with different needs and requirements. There are a large number of enterprises that have started looking at EMM service providers that can offer customized products and services. While some companies look for a nimble solution, others wish for plug-n-play products that cater to their specific needs. 42Gears EMM solution offers a scalable product architecture that can give tough competition to other market vendors, both product product quality and price point.
When does the Airbnb API launch?
One way you can get access to the Airbnb API is through AirGMS (cloud-based Airbnb management vacation rental software). Thanks to the native integration that AirGMS has with Airbnb, companies that use the new AirGMS API will get Airbnb data from them. This can be really useful for developers who are looking to build custom solutions that take advantage of the features that are native to Airbnb.For more info about how you can access the AirGMS API that was recently made available, click here.
