Sorry if I was not clear. I understand what a proof of work is. I was just wondering what the specific proof of work was going to be for the blockchain alluded to in the article. If it's a distributed network ledger based on a Byzantine fault tolerant consensus algorithm then it seems like it would be susceptible to attack if > 1/3 of the nodes on the network were traitors to the purpose of the network. What prevents a large numbers of traitorous nodes from joining the network to serve the purpose of a single party? It seems like Bitcoin's system of requiring a computationally expensive proof of work (SHA-256 to find a nounce) makes it harder for a large number of traitorous miners to exceed the 1/2 network threshold required to make a double-spend stick.
Most of these blockchain articles fail to mention the important technical details about how a blockchain would be used. The questions I'd like to see answered are: What is the "proof of work" used by the blockchain to decide which node gets to commit to the permanent blockchain record? How will the blockchain handle if a pool of nodes consisting of > 50% of the computing power for proof of work decides to "double spend" or alter a blockchain record? How decentralized will access to the blockchain be? Will it only be companies or individuals with access? Who decides who gets access? What is the minimum amount of time you will need to wait for a blockchain record to be permanent and unable to be altered? How big will blockchain be on disk? Will each node need a full copy of the blockchain?
Yes. I recommend Firefox's password manager which can encrypt passwords stored in your browser with a master password. Then add to that Mozilla's sync feature to store an encrypted copy of your passwords on Mozilla's server. They are stored encrypted and cannot be recovered without the sync password and e-mail access. If you don't trust Mozilla's server, despite the passwords being encrypted, they provide the open source software so you can run your own server to sync your encrypted passwords to.
If someone (you or hacker) does not know the sync password and resets the password with access to your e-mail account, it will not give them access to the passwords that were sync'd previously. This is good because it keeps a hacker from being able to just hack your e-mail account then use that to get access to all your passwords.
You are wrong. In my example, using ==, it will report equal. Using ===, it will report not equal. $ php -r "if (\"0E54321\" === \"0E12345\") { echo \"equal\n\"; } else { echo \"not equal\n\"; } " not equal $ php -r "if (\"0E54321\" == \"0E12345\") { echo \"equal\n\"; } else { echo \"not equal\n\"; } " equal
The string "0E54321" and "0E12345" both get converted into the integer 0 for comparison purposes when you only use ==.
The 5% gross fee is only after the first $3000 made per quarter. Also this royalty fee is only for the free version of unreal engine that has no monthly/upfront cost. Epic offers alternative licensing schemes if a developer would prefer to pay upfront for UE4 instead of paying a 5% royalty. https://www.unrealengine.com/c...
Perhaps they want a system that can be used by multiple companies besides just Walmart. If I was a farmer whose food might end up at Walmart, Target, Whole Foods, etc why would I want to submit tracking data multiple times to multiple companies' databases when I could just submit it once to this 3rd party IBM based blockchain and then any end-company which uses it can have the info they need.
The production of products using raw milk is not illegal in the EU. They are authorized with some very reasonable stipulations concerning the health of the animals producing the raw milk, labeling the product and making sure the conformity of the milk is consistent.
Some officials in the European Union (EU) want the United Kingdom (UK) to invoke article 50 of the Lisbon treaty before beginning any negotiations. The Lisbon treaty amended the Treaty on European Union (TEU) and the Treaty on the Functioning of the European Union (TFEU). The TEU and TFEU form the constitutional basis of the EU. The UK agreed to the Lisbon treaty when their house of commons debated and passed it on Jan. 21st, 2008.
Invoking article 50 of the Lisbon treaty simply means that the UK would be officially notifying the EU of their intention to leave the EU. The UK and EU would then have up to 2 years to negotiate the UK leaving the EU. The EU council could extend this 2 year deadline if an extension was agreed to by the UK. Once invoked they would be automatically not in the EU, which just means not subject to the TEU and TFEU treaties, after 2 years if no agreement could be met. If the UK changed their mind and wanted to cancel the leaving process then they would have to invoke article 49 during that 2 year period.
As long as users of Google, in your scenario, could continue to view all search results, regardless of moderation, why would it matter? Here on Slashdot we can all view all the posts regardless of the moderation. Negatively moderating the post does not change where it shows up in the list of posts. It's still there for all to see whom choose to see it.
If a user decides to subscribe to the group think of moderation and browse only at +5 they see what they the group wants them to see. If on the other hand a user decides to ignore the group think and browse at -1, they see things as they are. The control and choice is entirely in the hand of the viewer.
I agree with you that sometimes a moderator will negatively moderate a post they do not agree with. I disagree that this is censorship. A viewer's ability to see your post has not been suppressed. Every viewer of this website can see all the posts no matter the rating on the post. Some viewers will choose to look at all the posts while other viewers will choose to only look at posts which their peers have moderated to a certain level.
Walmart has a better selection of Amy's(tm) organic frozen food that is less expensive than most of the other generic grocery stores in my city. The exact same frozen organic food items are available at Nature's Grocer and Whole Foods in my city but are more expensive. Why should I pay more for the same item at those other stores? Now granted there are some additional brands of frozen organic foods at Nature's Grocer and Whole Foods but given the increased cost I don't see a reason to shop there.
It's a meal box. Unless you don't eat fast food at all or don't order food to-go from restaurants, surely you've eaten tasty food out of small cardboard boxes before. Personally I don't eat out of a bucket either because I'm snobbish about eating meat on a bone with my hands. I'm not caveman. I don't need to hold the bones of the animals that have been slaughtered for my nourishment. Usually only *that* kind of fried chicken is sold in buckets.
KFC in India has many vegetarian dishes to choose from. In addition to fried chicken sandwiches and strips they have fried vegetable "strips" and fried vegetable sandwiches. They have several spicy chicken choices we don't have in US KFC as well that are quite tasty.

You can also use DRBD (Distributed Remote Block Device) https://www.drbd.org/en/ to replicate block devices between servers.
Btrfs and ZFS have metadata and data checksum support.
XFS has only metadata checksum support.
You are wrong. In my example, using ==, it will report equal. Using ===, it will report not equal.
$ php -r "if (\"0E54321\" === \"0E12345\") { echo \"equal\n\"; } else { echo \"not equal\n\"; } "
not equal
$ php -r "if (\"0E54321\" == \"0E12345\") { echo \"equal\n\"; } else { echo \"not equal\n\"; } "
equal
The string "0E54321" and "0E12345" both get converted into the integer 0 for comparison purposes when you only use ==.
The documentation clearly explains this behavior. I'll link it again for you.
Type Juggling
String Conversion
PHP has a comparison operator === that evaluates if the two things it is comparing are equal and of the same type.
$ php -r "if (\"0E54321\" === \"0E12345\") { echo 'equal'; } else { echo 'not equal'; } "
not equal
Without ===, variable type conversion can cause a string containing numbers to be converted to an integer. See these links for details:

Wesley Crusher was awesome. I loved him when I was a teenage boy.
If the screen is indeed 720P, that's 44% of pixels of 1080P. So down-clocking the GPU by 40% seems fine to me.

You can keep the 6100mAh charger. The meal, including charger, costs about 149 rupees ($2.20).
