Based on yesterday's discussion at Dan Allosso's Book Club, we don't include defense spending into the consumer price index for calculating inflation or other market indicators. What other things (communal goods) aren't included into these measures, but which potentially should be to take into account the balance of governmental spending versus individual spending. It seems unfair that individual sectors, particularly those like defense contracting which are capitalistic in nature, but which are living on governmental rent extraction, should be free from the vagaries of inflation?
Throwing them into the basket may create broader stability for the broader system and act as a brake via feedback mechanisms which would push those corporations to work for the broader economic good, particularly when they're taking such a large piece of the overall pie.
Similarly how might we adjust corporate tax rates with respect to the level of inflation to prevent corporate price gouging during times of inflation which seems to be seen in the current 2023 economic climate. Workers have seen some small gains in salary since the pandemic, but inflationary pressures have dramatically eaten into these taking the gains and then some back into corporate coffers. The FED can increase interest rates to effect some change, but this doesn't change corporate price gouging in any way, tax or other policies will be necessary to do this.

Sustainable consumption scholars offer several explanations forwhy earth-friendly, justice-supporting consumers falter when itcomes to translating their values into meaningful impact.
- Paraphrase
- Claim
- earth-friendly, justice-supporting consumers cannot translate their values into meaningful impact.
- Evidence
- “the shading and distancing of commerce” Princen (1997) is an effect of information assymetry.
- producers up and down a supply chain can hide the negative social and environmental impacts of their operations, putting conscientious consumers at a disadvantage. //
- this is a result of the evolution of alienation accelerated by the industrial revolution that created the dualistic abstractions of producers and consumers.
- Before that, producers and consumers lived often one and the same in small village settings
- After the Industrial Revolution, producers became manufacturers with imposing factories that were cutoff from the general population
-
This set the conditions for opaqueness that have plagued us ever since. //
-
time constraints, competing values, and everyday routines together thwart the rational intentions of well-meaning consumers (Røpke 1999)
- assigning primary responsibility for system change to individual consumers is anathema to transformative change (Maniates 2001, 2019)
-
This can be broken down into three broad categories of reasons:
- Rebound effects
- https://jonudell.info/h/facet/?max=100&expanded=true&user=stopresetgo&exactTagSearch=true&any=jevon%27s+paradox
- increases in consumption consistently thwart
effciency-driven resource savings across a wide variety of sectors (Stern 2020).
-sustainability scholars increasingly critique “effciency” both as:
- a concept (Shove 2018)
- as a form of“weak sustainable consumption governance” (Fuchs and Lorek 2005).
- Many argue that, to be successful, effciency measures must be accompanied by initiatives that limit overall levels of consumption, that is, “strong sustainable consumption governance.
-
Attitude-behavior gap
-
Behavior-impact gap
- Rebound effects
-
The resulting focus on saving the world as a consumer, onegreen-lifestyle action at a time, blocks inspirational avenues to work-ing collectively as citizens toward the good life.
// key observation
-
People cannot reason and weigh every consumer decision every timethey act. Most of the hundreds of small decisions we make are basedon daily routines. We simply would not be able to function otherwise.And our routines, in turn, are strongly infuenced by their social andmaterial contexts. Time, societal norms of comfort and appropriatebehavior, and fnancial structures, all play a role here. Breaking rou-tines and practices requires far more than the provision of informationabout products and product use. It requires a change in the institu-tions and structures supporting them.
// argument against consumer sovereignty
-
Another is strate-gic coordination: a great many consumers must make the same productchoices at the same time, with persistence. But this requires a level ofdiligence, focus, conviction, and resistance to greenwashing that doesnot emerge spontaneously. It comes from collective action, most oftenpromoted and organized by civil society organizations.
// - indeed - coordinated collective action is what is missing here
-
The starkest danger of the “consumer in charge” narrative is that itdepoliticizes the challenges before us, at a time when a citizen politicsis most called for. With consumers in charge, only the softest and mostbenevolent policy interventions are required from governments, likeproviding consumers with information on the environmental and so-cial characteristics of products, and information on how to use theseproducts in a better (especially more effcient) way. For these reasons,the consumer sovereignty narrative is attractive to politicians, as itshifts responsibility away from producers, retailers, and those taskedwith regulating commercial activity
// - this, however, can be transformed through coordination. After all, it's the same principle of having enough people in consensus - one is in the economic arena, the other is in the political (voting). We can and should do both
-
The advent of a consumer sovereignty/individual control narrativeparallels the re-emergence, in the early 1980s, of neo-liberalism, a po-litical and social philosophy that emphasizes individual responsibilityfor larger social conditions.
// - consumer sovereignty, neoliberalism and democracy have elements in common of the individual having some form of power to determine collective decision

Unlike a cryptocurrency like Bitcoin, the digital yuan is issued directly by China’s central bank and does not depend on a blockchain. The currency has the same value as its analog equivalent, the yuan or RMB, and for consumers the experience of using the digital yuan is not that different from any other mobile payment system or credit card. But on the back end, payments are not routed through a bank and can sometimes move without transaction fees, jumping from one e-wallet to another as easily as cash changes hands.
Not a cryptocurrency, not a bank card

The processing systems fee is generally fairly low, around one 10th of a percent of the total purchase. There's a large market the merchant can choose from, which can keep this cost down. Then there's the credit card's network fee, around a quarter of a percent. And the largest fee of the system also happens here. The interchange fee, it's usually around two to 3%.
Credit card fees
The interchange fee is variable, and is paid to the bank. If a merchant wants to accept a network's cards, it must accept all of the variable interchange fees.

From society’s perspective, the wide availability of cheap credit is generally considered a good thing, as it allows for productive investment, consumption smoothing over consumers’ lifetimes, and a form of risk-pooling not entire dissimilar to public support or insurance programs. (It is underappreciated that consumer credit is, effectively, one of the largest welfare programs in the United States. Chargeoffs of e.g. credit card debt effectively transfer a private benefit to the defaulting consumer in return for a diffuse cost to the rest of the public, mediated by the financial industry; the net amount of them is almost as much as food stamps.)

What happens in Indonesia when a textile manufacturer illegally dumps dye waste!
This is an example of the manufacturer / consumer dualism created by the Industrial Revolution. Since manufacturers have become a separate layer that no longer exist as part of the community, as artisans once did, along with globalized capitalism, the consumer does not know the life history of the product being consumed. The sensory bubble limits what a consumer can directly know.
One answer is to promote a trend back to local and artisan production. Relocalizing production can empower consumers to inspect producers of the products they consume, holding them accountable.
Another answer is to develop globalized trust networks of producers who are truly ethical.
Cosmolocal production has networks by the commons nature can promote such values.

EU consumer law applies to contracts or other legal relationships between consumers (on one side) and professionals, businesses, companies on the other (B2C). It does not apply to B2B (e.g. a supermarket places an order with its fruit supplier) or C2C relationships (e.g. I sell my old bike over eBay).

In the US, there is no one national law in regards to returns/refunds for purchases made online as in most cases, this is implemented on a state-by-state basis, however, under several state-laws, if no refund or return notice was made visible to consumers before purchase, consumers are automatically granted extended return/refund rights. In cases where the item purchased is defective, an implied warranty may apply in lieu of a written warranty

When Casper filed its S-1 in January, analysts, investors, and business nerds descended on the document like vultures. Not only was it a precarious moment to take a startup public, it was the first time anyone could actually access the raw numbers under the hood of a DTC. “The economics work better if Casper sent you a mattress for free, stuffed with $300,” jabbed NYU Stern marketing professor and tech doomsayer Scott Galloway. “This appears to be Casper’s business,” tweeted number-crunching Atlantic columnist Derek Thompson. “Buy mattress at $400. Sell at $1,000. Refund/return 20% of them. Keep $400, on avg. Then spend $290 of that on ads/marketing and $270 on admin (finance, HR, IT). Lose $160. Repeat.”

As with neoliberalism more generally, New Public Management is invisible, part of a new “common sense” that has somehow become hegemonic, whereby the “entrepreneurial spirit” has infused the public sector, leading to “businesslike government”. As with the claims of neoliberalism more generally as to its positive outputs in terms of prosperity, NPM has never been shown to have been successful even in its own terms. NPM “introduced punishments and rewards to produce better services with lesser staff. Instead of having freed energies and creativity of employees formerly shackled by their bureaucratic turfs, NPM reforms have bound energies into theatrical audit performances at the cost of work and killed creativity in centralizing resources and hollowing out professional autonomy... Fundamental deprivation of the legitimacy of public employees . . .has traumatized many most-committed employees and driven others toward a Soviet-type double standard.” (Juha Siltala, New Public Management : The evidence-based worst practice?, Administration; Vol. 45, No. 4.; 2013 pp. 468-493) Sekera quotes Christopher Pollitt et al., who “after compiling a database of 518 studies of NPM in Europe, determined that “more than 90% of what are seen by experts as the most significant and relevant studies contain no data at all on outcomes” and that of the 10% that had outcomes information, only 44% of those, or 4% of the total, found any improvements in terms of outcomes.” But in the end, the point of NPM is less that of measureable outcomes, and more that of the ideological victory of turning the public and its good into customers exercising their “choices” (see tax revolt example in Duggan), along of course with the radical disempowering of public administration workers and their unions, instituting “cost savings” by cutting their real income and putting more and more of the public sector’s production directly into the profit-making market.

The cache for consumers has a default maximum size of 64. If you expect to be handling more than (64 * number of executors) Kafka partitions, you can change this setting via spark.streaming.kafka.consumer.cache.maxCapacity.

A better alternative is at least once message delivery. For at least once delivery, the consumer reads data from a partition, processes the message, and then commits the offset of the message it has processed. In this case, the consumer could crash between processing the message and committing the offset and when the consumer restarts it will process the message again. This leads to duplicate messages in downstream systems but no data loss.
This is what SECOR does.
-
By electing a new leader as soon as possible messages may be dropped but we will minimized downtime as any new machine can be leader.
two scenarios to get the leader back: 1.) Wait to bring the master back online. 2.) Or elect the first node that comes back up. But in this scenario if that replica partition was a bit behind the master then the time from when this replica went down to when the master went down. All that data is Lost.
SO there is a trade off between availability and consistency. (Durability)
-
keep in mind that these guarantees hold as long as you are producing to one partition and consuming from one partition.
This is very important a 1-to-1 mapping between writer and reader with partition. If you have more producers per partition or more consumers per partition your consistency is going to go haywire

On every received heartbeat, the coordinator starts (or resets) a timer. If no heartbeat is received when the timer expires, the coordinator marks the member dead and signals the rest of the group that they should rejoin so that partitions can be reassigned. The duration of the timer is known as the session timeout and is configured on the client with the setting session.timeout.ms.
Time to live for the consumers. If the heartbeat doesn't reach the co-ordindator in this duration then the co-ordinator redistributes the partitions to the remaining consumers in the consumer group.

The high watermark is the offset of the last message that was successfully copied to all of the log’s replicas.

Kafka scales topic consumption by distributing partitions among a consumer group, which is a set of consumers sharing a common group identifier.
Topic consumption is distributed among a list of consumer group.

Kafka consumer offset management protocol to keep track of what’s been uploaded to S3
consumers keep track of what's written and where it left off by looking at kafka consumer offsets rather than checking S3 since S3 is an eventually consistent system.
-
Data lost or corrupted at this stage isn’t recoverable so the greatest design objective for Secor is data integrity.
data loss in S3 is being mitigated.

incidents are an unavoidable reality of working with distributed systems, no matter how reliable. A prompt alerting solution should be an integral part of the design,
see how it can hook into the current logging mechanism
-
Consumers in this group are designed to be dead-simple, performant, and highly resilient. Since the data copied verbatim, no code upgrades are required to support new message types.
exactly what we want

The Kafka cluster retains all published records—whether or not they have been consumed—using a configurable retention period. For example, if the retention policy is set to two days, then for the two days after a record is published, it is available for consumption, after which it will be discarded to free up space. Kafka's performance is effectively constant with respect to data size so storing data for a long time is not a problem.
irrespective of the fact that the consumer has consumed the message that message is kept in kafka for the entire retention policy duration.
You can have two or more consumer groups: 1 -> real time 2 -> back up consumer group

For a topic with replication factor N, we will tolerate up to N-1 server failures without losing any records committed to the log.
for Eg for a given topic there are 11 brokers/servers and for each topic the replication factor is 6. That means the topic will start loosing data if more than 5 brokers go down.

The way consumption is implemented in Kafka is by dividing up the partitions in the log over the consumer instances so that each instance is the exclusive consumer of a "fair share" of partitions at any point in time. This process of maintaining membership in the group is handled by the Kafka protocol dynamically. If new instances join the group they will take over some partitions from other members of the group; if an instance dies, its partitions will be distributed to the remaining instances.
The coolest feature: this way all you need to do is add new consumers in a consumer group to auto scale per topic
-
Consumers label themselves with a consumer group name
maintain separate consumer group per tenant basis. Helps to scale out when we have more load per tenant.

If this were true for modern society, it has multiplied in ourage of social media, in which control and value are indissolubly linked to the machine ensemblesthat comprise contemporary digital infrastructures.
I have studied in my International Marketing course here how social media is a cultural institution in society and has an extremely powerful influence on societal structures regarding preferences, levels of acceptance of products/technology, and how consumers are influenced to use them.
