Quantum Fields: The Real Building Blocks of the Universe - with David Tong

The very best theories we have tell us that the fundamental building blocks of nature are not particles, …but … fluid-like substances which are spread throughout the entire universe and ripple in strange and interesting ways.  That’s the fundamental [physical] reality in which we live. … We call them fields.


Angela Walch, The Bitcoin Blockchain as Financial Market Infrastructure: A Consideration of Operational Risk

For another “AI”
and governance issue.

Walch’s argument can be retargetted as a problematization of 
the present financial system itself, and of any infrastructure software technology...



Abstract:

Blockchain” is the word on the street these days, with every signifi- cant financial institution, from Goldman Sachs to NASDAQ, experimenting with this new technology. Many say that this remarkable innovation could radically transform our financial system, eliminating the costs and inefficiencies that plague our existing financial infrastructures, such as payment, settlement, and clearing systems. Venture capital investments are pouring into blockchain startups, which are scrambling to disrupt the “quadrillion”- dollar markets represented by existing financial market infrastructures. A debate rages over whether public, “permissionless” blockchains (like Bitcoin’s) or private, “permissioned” blockchains (like those being de- signed at many large banks) are more desirable.

Amidst this flurry of innovation and investment, this Article inquires into the suitability of the Bitcoin blockchain to serve as the backbone of financial market infrastructure, and evaluates whether it is robust enough to serve as the foundation of major payment, settlement, clearing, or trading systems.

Positing a scenario in which the Bitcoin blockchain does serve as the technology enabling significant financial market infrastructures, this Article highlights the vital importance of functioning financial market infrastructure to global financial stability, and describes relevant principles that global financial regulators have adopted to help maintain this stability, focusing particularly on governance, risk management, and operational risk.

The Article then moves to explicate the operational risks generated by the most fundamental features of Bitcoin: its status as decentralized, open- source software. Illuminating the inevitable operational risks of software, such as its vulnerability to bugs and hacking (as well as Bitcoin’s unique “51% Attack” vulnerability), uneven adoption of new releases, and its opaque nature to all except coders, the Article argues that these technology risks are exacerbated by the governance risks generated by Bitcoin’s ambiguous governance structure. The Article then teases out the operational risks spawned by decentralized, open-source governance, including that no one is responsible for resolving a crisis with the software; no one can legitimately serve as “the voice” of the software; code maintenance and repair may be delayed or imperfect because not enough time is devoted to the code by volunteer software developers (or, if the coders are paid by private com- panies, the code development may be influenced by conflicts of interest); consensus on important changes to the code may be difficult or impossible to achieve, leading to splits in the blockchain; and the software developers who “run” the Bitcoin blockchain seem to have backgrounds in software coding rather than in policy-making or risk management for financial mar- ket infrastructure.

The Article concludes that these operational risks, generated by Bitcoin’s most fundamental, presumably inalterable, structures, strongly undermine the Bitcoin blockchain’s suitability to serve as financial market infrastructure.

backup | archive strategy (thanks SuperDuper)

backup | archive strategy which may be generally useful  (from SuperDuper)
Time to cycle out our off-site drive?

Introduction

First, a little of the background and philosophy behind SuperDuper!

Backing up is one of those things that never seems important until something goes horribly wrong, and things never go horribly wrong until the worst possible moment. Many backup programs do too much for the “normal” user: rather than making it easy and faster to get their data backed up, they overcomplicate the process to the point of frustration.

That complexity can alienate and confuse users, and a proprietary, single- vendor format leaves them without an alternative should a problem arise. We think it’s important that any solution be easy to understand, usable, and not have any “lock in”.

Staying Balanced

So, to determine whether that complexity is worth adding, it’s important to ask: when do most people need to restore? In general, we’ve found that “regular users” (and by that, I mean real “end users” like yourself) need to use their backups when:

  • They’ve made a “bad mistake”, like accidentally deleting an important file, or overwriting one (this kind of mistake is almost always recognized immediately)

  • Their drive (or computer) fails catastrophically, requiring a full restore

  • They sent their computer in for service, and it came back wiped clean

  • An application they installed, or a system update, caused their system

    to become unusable/unstable

    None of these situations require much other than a high-quality, up-to-date, full copy backup. (The last has a better solution than a backup – a “Sandbox” – which we offer in SuperDuper! as well.)

    Covering the 99% Case

    Given that, it’s pretty easy to see that most end users don’t need to retrieve a two-year-old (or even six-month old) version of a file from a backup. (An archive is a different thing: I’m talking about backups.) It’s just not that common a case. Developers, on the other hand, do need older versions of files, but they should be using a version control system: something a backup should absolutely not be.

    But, it is possible that a user won’t notice a problem in a “bad file” until they’ve already overwritten their backup, thus losing any chance of recovery with a “full copy”. While this is a problem for some, we have a good solution: rotate more than one full backup.

3

Any need for this kind of “temporal rollback” can be significantly reduced with a single rotation – say, on a weekly basis – and nearly eliminated with two, a weekly and a monthly. It’s incredibly rare that, on a non-archival basis, you’d need to go back more than four weeks.

Simple to Understand

The advantages to this kind of approach are many, not the least of which is that a non-technical user can easily understand what’s going on. It’s incredible how many people are confused by conventional backup terminology – “incremental”, “differential”, backups “sets” and the like. And, complicated storage mechanisms require a significant amount of expertise to perform a full recovery in the event of that all-too-common disaster: the total drive failure.

Simple to Restore

With SuperDuper!, recovery in that situation is literally a matter of booting from your most recent backup. And restoration – which, should you be on deadline, you need not do immediately – is just a matter of replacing the drive and copying back.

Individual files are also easy to restore: just drag and drop from the backup. (Yes, applications without drag-and-drop install, or system-level files, are harder, but can typically be reinstalled/archive-and-installed should that be necessary... or, see the Sandbox for another rather unique idea...)

Use It or Lose It

SuperDuper!’s approach is the kind of thing that regular end users like yourself can do, and feel confident about.

We know your time is valuable, and that a backup isn’t useful unless it’s recent and includes the files you expect. We’ve made the process of backing up extremely simple, and – with Smart Update – we’ve also made it fast and efficient.

Global Cafe - Plates, flatware & glasses

Thanks Ri!

what’s the total cost ?  $50-$80 for 10 sets would be fine.  Can you work w Pete on actual purchase?

Let’s get ceramic plates and metal flatware.

Simple classy design is good.

It would be really great  to get plates that can hold a projected image.
eg matte surface like “stoneware” 
white is fine, but  projecting into dark slate gray could yield images with much richer color and good contrast.

(I’m not sure about exactly which colors are optimal — best to experiment by shining a portable projector onto the plate — but there’s no time. :)

Global Cafe + Object Theater: toward Media Architecture Biennale 2020

Hi Yanjun, Shomit, Christy, Haakon, (other interested folks welcome!)

Shall we build the Global Cafe and related works into a joint project  on augmented social refreshment space
the we can exhibit at world-level venue such as:

Media Architecture Biennale MAB 2020 Utrecht

Ingredients:

The local responsive objects as well as telematically mated objects have behaviors that are designed first 
with social & dramaturgical power (think experimental puppet theater), and 
with experiential research questions such as:

I think the Global Cafe Team should receive the notification of a shared Google "Cafe Project" folder.  If you are not, please remind me. 
I built a Google Project folder in which I uploaded all files, clips, a poster and a note(DRAFT) from my understanding and a summary based on Xin Wei and Christy's emails during these days for this project. I hope this is helpful for our Monday meeting (9/16, 3-4) and future communication. The Note named "notes for TEAM to edit" is a mutual place for us to share thoughts, suggestions, resources, even an online discussion space. I hope this helpful for teamwork and also for Xinwei, Christy, Lauren to edit any suggestion on here to us.

Hi Everyone, 

To follow up Christy –

Christy Spackman, Lauren Hayes and I think the social form of the meal / cafe gives a concrete “boundary object” in which to try out speculative, experimental artistic / computational techniques, as well as  conceptual questions.  It is rich enough to be a site for individual special research work, and simultaneously meaningful to people from any walk of life.  So let’s make the meal / cafe social form one of Synthesis focal research platforms.  (The other remains improvisatory events and participatory steering of complex systems in responsive environments.)

I’m hoping that this term, with Shomit, Yanjun, Ri, and Andrew R, Garrett, and 
supported by key Synthesis researchers, we can build a new generation of experiments that will lead to publications and internationally exhibitable work that can attract support from outside ASU, even outside the academy.

We’re very lucky to have faculty like Lauren and Christy interested in advising us in this work.
We are interested in helping focus the really exciting explorations into tangible iterations.

Yanjun, Shomit, Ri, Garrett, 
In order to make progress let’s propel this with the initial constraints and questions that Christy and I pose.  To repeat:

Imagine you are at a cafe. Three people are there. 
1) who are the three people whose interaction you want to prototype?
2) what might a "normal" script be for those interactions?
3) what new script(s) are you hoping to inspire?


In order to have impact, we’ll need to have an adequate production level : I will take responsibility for this — with Connor and Pete as “goto” experts, as well as Todd, Lauren, Brandon, and the Tech Team (Pete, Luke, Ozzie).   Remember the Tech Team are advisors but they have very limited time to actually fabricate solutions.   So it will be important to collanorate, recruit students, and pool skills.

Let’s talk today if we can .

I’ll Zoom in in about 15’ as soon as I get to a quite spot  and hang out near my zoom for a couple of hours as long as I can today.

PS  Thanks Garrett, Shomit, Yanjun Andrew’s for earlier ideas…
