In August 2017, the MIT Digital Currency Initiative took a look at the IOTA source code and found that the IOTA hash function Curl produced collisions when different inputs hash to the same output. The team developed an attack by means of which they were able to forge signatures on IOTA payments. The full vulnerability report can be read here and is explained in a blog post by Neha Narula, director of the Digital Currency Initiative at the MIT Media Lab. Since IOTA’s team was informed about the vulnerabilities of Curl, they have been using Kerl, which is Keccak-384 with conversion from 243 trits to 48 bytes using two’s complement. Koen Maris, CTO in the field of cyber security for Atos with a background in software engineering, ethical hacking and security solutions integration. The IOTA Foundation ran some simulations with its MCMC tip-selection algorithm in the Tangle and presented the preliminary results in a paper on November 6, 2017.
The Meaning Of Eli5
For additional information, check out this IOTA Japanese Fan Site deep dive into MAM. As you can see, as new transactions were added to the Tangle, two branches formed as a result of the conflict caused by the double spend, but the top branch was more favored than the bottom branch. At some point, as the top branch gains in cumulative weight, legitimate nodes using the MCMC tip-selection algorithm will not select tip 7 to confirm. As a result, transactions t, y, 6 and 7 will eli5 meaning never become fully confirmed. In the diagram above, a malicious user added two conflicting transactions in different parts of the Tangle in an attempt to double spend. Subsequent nodes might only have one of these conflicting transactions in their validation path, so they will approve these transactions. However, at some point, a node will try to issue a transaction that selects two tips that show the conflict and it will consequently fail to confirm the selected tips.
The simulation of the Tangle using the MCMC tip-selection algorithm differs from the white paper’s predictions. Specifically, note that when α increases from 0.001 to 5, the number of tips goes from a widely fluctuating average to a linear function that grows significantly eli5 meaning over time. This narrow chain would render IOTA ineffective as a distributed ledger, since many sub-chains of transactions would be orphaned and left unconfirmed. As previously mentioned, the success of the tip-selection algorithm determines the success of the Tangle.
What is Zombieing in dating?
Even if you’ve never been ghosted — or ever been the ghoster — you probably know what it is: when someone you’re dating or “talking to” disappears out of the blue. No, this isn’t when you’re ghosted on Halloween. Zombieing is when someone ghosts you, but then decides to come back into your life like nothing happened.
The grey transactions (v–y) are newly added, unconfirmed transactions, also called tips. The blue transactions (n–u) are considered partially confirmed, meaning their cumulative weight is not high enough for them to be considered confirmed with a high level of certainty. Let the two random walkers that reach the tip set first determine which two tips to approve. However, the algorithm will have to discard random walkers that reach tips too early as they may have landed on “lazy tips”—transactions that selected confirmed transactions to confirm rather than unconfirmed tips.
What is curving in dating?
It’s rejection with a smile
Now, there’s a new term to worry about. Introducing “curving”: when someone rejects you in a way that is so sneaky, you probably won’t even recognise it as rejection. It’s a way of letting someone down without actually telling them you’re no longer interested.
The large size of these transactions raises questions about the technology’s suitability for IoT devices with limited storage. In October, the Coordinator was taken offline temporarily after an unplanned shutdown to protect users from an ongoing attack on the network. When the Coordinator eli5 meaning was relaunched, some IOTA users found their token balance was zero and had to go through a claims process to recover their funds. This portion of the document summarizes some of the areas of concern that exist within the IOTA community and broader blockchain community.
if the network address in the original request is not null, compares the source’s IP address to your network address within the TGT. The Ticket Granting Server will first check the KDC database to see if the HTTP Service exists. The Authentication Server will check if you are in the KDC database. This check is only to see if you exist; no credentials are checked. The KDC itself is encrypted with a master key to add a layer of difficulty from stealing keys from the database.
What was the first acronym?
The earliest known use of initialism is from 1844, in an article in “The Christian’s Monthly Magazine and Universal Review” discussing SPQR, an abbreviation of the Latin phrase Senatus Populusque Romanus (“The Senate and People of Rome”).

Primary keys are a fundamental part of a data warehouse, but often people regard them as a technicality- something to tack onto the end of a table creation. In reality, they’re the very building block of tables and reports. When you really dive into it, primary keys are a concept we understood as children but later gave a fancy name to. As always, notes are the technical terms or concepts that Rhys doesn’t need to know, but you may want to know.

If not, segregated systems and a lack of access to metrics and KPIs may be holding you back. Enterprise resource planning software is designed to address these challenges. For companies that want a mixture of both to meet their business requirements, there is the hybrid model. This is eli5 meaning where some of your ERP applications and data will be in the cloud and some on premise. In cloud ERP, the software runs on a provider’s cloud computing platform. There is also a choice of utilizing a public or private cloud, which is gaining acceptance because of the low upfront costs.
In order to issue a transaction, the issuing node selects two other transactions in the Tangle. Ideally these two other transactions are as-yet-unconfirmed tips, selected using the Markov Chain Monte Carlo tip-selection algorithm. In order to issue a transaction into the Tangle, a node has to select two transactions already in the Tangle to approve. The node approves the two selected transactions by verifying eli5 meaning their signatures and confirming that they are not conflicting with any of the transactions it approves either directly or indirectly. The issued transaction is not confirmed in the Tangle until other transactions have confirmed it through the same process. Transactions can be confirmed with either higher or lower certainty. There is no mechanism for token mining and no further IOTA tokens will be created.
