Timestamp Quotes

I want you to travel roads that aren’t there, build bridges where none exist, sing songs that haven’t been written. I want you to love yourself fiercely, love others courageously, love life unapologetically. I want you to shatter expectations, break out of cages, and dance in crowded streets while it rains.

I am the offspring of their sacrifice, the fruit of a freedom tree planted by the enslaved and watered with the tears of the shackled, the daydream of slave minds drunk with precious thoughts of liberty, the answered prayer of an oppressed people. Because they were, I am.  

The macrohistorical log is largely siloed across different corporate servers, on the premises of Twitter and Facebook and Google. The posts are typically not digitally signed or cryptographically timestamped, so much of the content is (or could be) from bots rather than humans. Inconvenient digital history can be deleted by putting sufficient pressure on centralized social media companies or academic publishers, censoring true information in the name of taking down “disinformation,” as we’ve already seen. And the advent of AI allows highly realistic fakes of the past and present to be generated.

Morgan Stanley or the U.S. federal government. Every ten minutes, like the heartbeat of the bitcoin network, all the transactions conducted are verified, cleared, and stored in a block which is linked to the preceding block, thereby creating a chain. Each block must refer to the preceding block to be valid. This structure permanently time-stamps and stores exchanges of value, preventing anyone from altering the ledger. If you wanted to steal a bitcoin, you’d have to rewrite the coin’s entire history on the blockchain in broad daylight. That’s practically impossible. So the blockchain is a distributed ledger representing a network consensus of every transaction that has ever occurred. Like the World Wide Web of information, it’s the World Wide Ledger of value—a distributed ledger that everyone can download and run on their personal computer.

When a read request comes in to a node, the data to be returned is merged from all the related SSTables and any unflushed memtables. Timestamps are used to determine which one is up-to-date. The merged value is also stored in a write-through row cache to improve the future read performance.

Different names in columns are possible in different rows. That is why Cassandra is both row oriented and column oriented. It should be remarked that there is no timestamp for rows.

The Map data structure gives efficient key lookup, and the sorted nature provides efficient scans. RowKey is a unique key and can hold a value. The inner SortedMap data structure allows a variable number of ColumnKey values. This is the trick that Cassandra uses to be schemaless and to allow the data model to evolve organically over time. It should be noted that each column has a client-supplied timestamp associated, but it can be ignored during data modeling. Cassandra uses the timestamp internally to resolve transaction conflicts.

Column Column is the smallest data model element and storage unit in Cassandra. Though it also exists in a relational database, it is a different thing in Cassandra. As shown in the following figure, a column is a name-value pair with a timestamp and an optional Time-To-Live (TTL) value:

If no time zone is specified, the time zone of the Cassandra coordinator node handing the write request is used. Therefore the best practice is to specify the time zone with the timestamp rather than relying on the time zone configured on the Cassandra nodes to avoid any ambiguities.

A value of the timeuuid data type is a Type 1 UUID which includes the time of its generation and is sorted by timestamp. It is therefore ideal for use in applications requiring conflict-free timestamps. A valid timeuuid uses the time in 100 intervals since 00:00:00.00 UTC (60 bits), a clock sequence number for prevention of duplicates (14 bits), and the IEEE 801 MAC address (48 bits) to generate a unique identifier, for example, 74754ac0-e13f-11e3-a8a3-a92bc9056ee6.

If the data is different on different replicas, Cassandra will return the copy with the most recent timestamp, ensuring that we are getting the most recently written copy of the row.

CREATE TABLE IF NOT EXISTS 'users' (   'id' int(10) unsigned NOT NULL AUTO_INCREMENT,   'username' varchar(255) COLLATE utf8_unicode_ci NOT NULL,   'password' varchar(255) COLLATE utf8_unicode_ci NOT NULL,   'email' varchar(255) COLLATE utf8_unicode_ci NOT NULL,   'phone' varchar(255) COLLATE utf8_unicode_ci NOT NULL,   'name' varchar(255) COLLATE utf8_unicode_ci NOT NULL,   'created_at' timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',   'updated_at' timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',   PRIMARY KEY ('id') ) ENGINE=InnoDB  DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=3 ;

Besides, the paper pushers refuse to let the world end until every form is turned in, timestamped and properly initialed. Apocalypse is the last gasp of bureaucracy.

In a little more detail, why is the Bitcoin blockchain so resistant to the rewriting of history? To falsify the “who” of a single transaction you’d need to fake a digital signature, to falsify the “what” you’d need to break a hash function, to falsify the “when” you’d need to corrupt a timestamp, and you’d need to do this while somehow not breaking all the other records cryptographically connected to that transaction through the mechanism of composed block headers. Some call the Bitcoin blockchain a timechain, because unlike many other blockchains, its proof-of-work mechanism and difficulty adjustment ensure a statistically regular time interval between blocks, crucial to its function as a digital history.

Tesla > NYT. Elon Musk used the instrumental record of a Tesla drive to knock down an NYT story. The New York Times Company claimed the car had run out of charge, but his dataset showed they had purposefully driven it around to make this happen, lying about their driving history. His numbers overturned their letters. Timestamp > Macron, NYT. Twitter posters used a photo’s timestamp to disprove a purported photo of the Brazilian fires that was tweeted by Emmanuel Macron and printed uncritically by NYT. The photo was shown via reverse image search to be taken by a photographer who had died in 2003, so it was more than a decade old. This was a big deal because The Atlantic was literally calling for war with Brazil over these (fake) photos. Provable patent priority. A Chinese court used an on-chain timestamp to establish priority in a patent suit. One company proved that it could not have infringed the patent of the other, because it had filed “on chain” before the other company had filed. In the first and second examples, the employees of the New York Times Company simply misrepresented the facts as they are wont to do, circulating assertions that were politically useful against two of their perennial opponents: the tech founder and the foreign conservative. Whether these misrepresentations were made intentionally or out of “too good to check” carelessness, they were both attempts to exercise political power that ran into the brick wall of technological truth. In the third example, the Chinese political system delegated the job of finding out what was true to the blockchain. In all three cases, technology provided a more robust means of determining what was true than the previous gold standards — whether that be the “paper of record” or the party-state. It decentralized the determination of truth away from the centralized establishment.

Don't worry I know the timestamp. Wait, what was the timestamp?

We can now see how the expansion of blockspace is on track to give us a cryptographically verifiable macrohistory, or cryptohistory for short. This is the log of everything that billions of people choose to make public: every decentralized tweet, every public donation, every birth and death certificate, every marriage and citizenship record, every crypto domain registration, every merger and acquisition of an on-chain entity, every financial statement, every public record — all digitally signed, timestamped, and hashed in freely available public ledgers.26 The thing is, essentially all of human behavior has a digital component now. Every purchase and communication, every ride in an Uber, every swipe of a keycard, and every step with a Fitbit — all of that produces digital artifacts. So, in theory you could eventually download the public blockchain of a network state to replay the entire cryptographically verified history of a community.25 That’s the future of public records, a concept that is to the paper-based system of the legacy state what paper records were to oral records.

The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power.

To past generations, You grew up in a time of tall trees and flowers. Stumbled through the dark, blameless and carefree. When you were at fault, you answered only to yourself. The pain you’ve caused others—now inconsequential—because no one was watching. You belong to a world of forgotten transgressions. Our generation blooms in the era of eyes and judgment. Where our mistakes are timestamped; our broken hearts livestreamed. But does this give you a right to throw stones at us? Self-growth is a long and winding road, and the ground we are treading is unlike any other. Please be patient with us. Be kind. Understand that we must lose our way, over and over, before we can find the best version of ourselves.

Music has that ability, you know. The ability to transmute your pain into something poetic. The ability to move your heart when it’s feeling joy or hold your hand when sadness is your only companion. It can time-stamp a perfect moment etching it into the archives of your mind. It transcends all other mediums. Music is the beginning and end, of every human emotion.

No!’ McNally’s sunken cheeks, usually a ghoulish pale yellow, were flushed. Adam scribbled another note, pushed it across the desk to Jonathan. The judge was watching him like a cat watching a spider. ‘Could we please show the CCTV from timestamp 11.54,’ Jonathan said. The officer did as he asked,

They explained the records that were held by the ice, the chemical isotopes, trapped gases, and dust particles that would permit a time-stamped window into past climates—benchmarks for the broadening recognition that a man-made increase in global temperature was underway.

No matter how many times I go back and forth between dreaming and dreading it, love always calls me back home. Through tender love songs and cute love stories and quirky rom-coms (which I actually don’t watch too often), it always manages to renew my faith in its existence. I may not have it yet, but I believe it’s out there somewhere waiting to find me or be found. That will always give me hope.

hey asshole u r missing a good time 2nite! Caleb’s text was time-stamped from an hour and a half ago. u still up? Mikah typed. u aren’t going to believe this shit. THE GUY is asleep in my bed right now. Mikah wasn’t sure that Caleb would still be awake, but it was only a moment before the screen lit up again. OMFG YOU SLUT! the message read. tell me EVERYTHING!!!!!!! not much 2 tell, Mikah typed. this is insane. still don’t even know his name. SCANDALOUS! A few long moments passed before Caleb continued. sry, hot trick @the bar. hard 2 focus. FOCUS! Mikah replied. I need help here. what do I do? Caleb’s response was quicker this time. Idk check his fucking pants for his DL. g2g, about to get some dick. night. xoxo

pick the write with the highest ID as the winner, and throw away the other writes. If a timestamp is used, this technique is known as last write wins (LWW).

The revolution will not be televised. It will be time-stamped on the block chain.

An important aspect of total order broadcast is that the order is fixed at the time the messages are delivered: a node is not allowed to retroactively insert a message into an earlier position in the order if subsequent messages have already been delivered. This fact makes total order broadcast stronger than timestamp ordering.
