Is the interesting part of Container Linux open-source? Can anyone fork it and build a similar offering, simpler than RHEL?
The author was more saying that this was going to be new way to fund startups, with coins that get speculatively gambled. So rather than crypto-coins being used as per the original dream of wonderful decentralised money with no payment fees and 'better than gold' store of wealth, in fact these coins are going to be the new way for companies to raise capital for taking their startup to the next level - so crypto-alt-coins are going to be replacing 'Kickstarter', 'YC' as well as the big VC companies as cited in the article.

So then the merit of a coin will be 'backed' by business fundamentals, i.e. is the business any good? So think of crypto-coins as shares, not this magic bean currency and everyone is a winner.
> I think this similarity is more than superficial. Energetic systems evolve over time to become tangled, correlated messes, without some other force counteracting this tendency (ie. refactoring).

Well... yes. That's entropy. Any system tends towards disorder.

> I wonder if DNA has analogous mechanisms.

DNA works differently, since there's an advantage to reusing code that naturally leads to spaghetti. Although it's not about minimizing energy- just that it's more likely to get successful code by adding onto existing code than adding a whole new section (unless you transclude it from bacteria/viruses).
You could argue that cartoons or line drawings are "adversarial examples" that are reliably identified by the human visual system as representing a particular thing despite being quantitatively nothing like what they're meant to represent.
It would be dependent on how deep the pipeline is. In the fairly common case of 1 to 2 app threads (ui + rendering) + GPU work you're looking at a pipeline depth of 3, so if it's doing 500fps that must mean no stage of the pipeline is taking longer than 2ms. With 3 pipeline stages that puts your worst-case latency at 6ms.
Why do you assume that identical twins have identical brains?

Brain physical structure is altered during lifetime experience, learning changes large physical properties of neurons e.g. forming some new synapses and pruning others.

Even at birth, identical twins have different fingerprints, different retinas and yes, different cellular structures of their brains. And that only diverges later.

It's not a given that a brain "3D printed from a snapshot of the exact cellular structure of your brain" would be sufficiently good copy, we know that there are other things that matter (e.g. various intra-cell properties and chemical concentrations within particular locations of those neurons) and there likely are some other things that matter but which we don't know yet.

However, assuming that we could make a sufficiently good copy, it would be undistinguishable from you. It would have the same behavior, reactions, memories, skills and understanding; it would have the same beliefs as you do - including a belief that it's you and that it has been you since your birth, supported by memories of living your life. If the copy is sufficiently good, barring the signs of the operation itself (scar tissue? machinery? video evidence of it being done) neither your relatives nor (new?) you yourself would be able to make a distinction.

Yes, you could argue that the new copy is different from the previous one, that it's not the same, that it lacks continuity. But that's arguing about what do we mean when we say "the same". If you didn't know that your parents had died, you'd have no way to tell when their copies come to celebrate christmas with you.
You shouldn't be able to run one unless you're a registered company. It has to be relatively easy to come after you for fraud as an investor.

They left out one. If you have a quality brand and you're not trying to compete on price and you have an upscale market, advertise on podcasts. I find most podcast ads to be interesting, maybe not applicable to me directly at the time but a product that would be on the top of my list if I were in the market for that category of item, and a lot of my recommendations come from hearing about products on podcasts.

Podcasters seem to be a lot more discerning about which products they will advertise.

On the other side of the coin,since most ads for podcast include some type of offer code, you can measure which podcasts are affective at driving sales.
> Most people would accept being able to see and interact with the world a prerequisite to consciousness.

People lacking sight, hearing, mobility, and similar would disagree.

By all means, we want the ability to interact with the world, bidirectionally. But that's not a prerequisite for consciousness. And if the only thing we manage, in the short term, is preservation and continued function, that would be a massive improvement, far larger and more important than the subsequent incremental steps towards I/O.

I'm honored!!! Thanks. Yes, the architecture is P2P/decentralized (see this talk https://youtu.be/5fCPRY-9hkc ), however:

- NAT Traversal sucks and WebRTC is still very glitchy. To get around this, it is easier/better to just run gun on your machine directly (not via a browser) and connect directly to other gun peers with their IP addresses. Then browsers can connect via websocket fallback, but as WebRTC gets better that will work too.

- Peer discovery is not built in by default, but should be trivial to do by starting with some bootstrapping peers, which as other peers connect to them everybody saves the new IP addresses to a common `gun.get('peers').set(IP)` table. So yes, it is easily possible, just not built in (I'm sure in the future we'll have a full fledged extension for it).

- re:"gossip" GUN automatically daisy chains updates through peers of peers, in an ad-hoc mesh-network manner.

Would love to chat more! What is your email? Mine is mark [atatatat] gunDB [dotdotdot] io !
Oh in that case I'm just confused - that's what I know as Einstein notation. Modern physics papers seemed to use much more complex notation, but I probably just misunderstood.

If we're talking about Einstein notation, then I'm a fan - `np.einsum()` is often a great way to create fast tensor computations with minimal code.
I'm pretty sure some alarms use a strobe light at a particular frequency combined with a loud 2kHz tone to discombobulate intruders. That's more sensory overload than an adversarial signal, though.

I'd expect a malicious adversarial example to be more like the ones discussed in Snow Crash or BLIT ( https://en.wikipedia.org/wiki/BLIT_(short_story) )
Sounds better than what I was quoted, so perhaps something changed. I was looking for a model where I paid for the data sitting there in full, but paid only partially for the idle VM capacity.
Seam carving is fascinating, and especially the first version of the algorithm really really simple to implement. However, that algorithm introduces certain artefacts - the boat in this picture[0] makes it pretty obvious.

The cause of these artefacts are mainly that the original algorithm did not look at energy that was introduced by removing a seam: each time this happens, the pixels adjacent to this seam become neighbours, which creates a new energy gradient. So sometimes removing the least-energy seam would produce a net increase in energy.

The original authors of the seam carving paper realised this[1], which lead to the obvious fix for it: instead of only looking at the current energy of a picture, and removing the least-energy seam, look how much of a net energy difference the removal of a seam would make, aka "forward energy".

A few years later another paper came out that used "forward gradient difference maps" which supposedly work even better, but to be honest the formulas described in that paper are too complex for me to understand[2]. Conceptually though, I think they just extended the original energy function (a simple Sobel operator[3]) with a few other ones that include orientation and others:

> The energy function measures the curvature inconsistency between the pixels that become adjacent after seam removal, and involves the difference of gradient orientation and magnitude of the pixels. Our objective is to minimize the differences induced by the removed seam, and the optimization is performed by dynamic programming based on multiple cumulative energy maps, each of which corresponds to the seam pattern associated with a pixel. The proposed technique preserves straight lines and regular shapes better than the original and improved seam carving, and can be easily combined with other types of energy functions within the seam carving framework

With that in mind, it shouldn't be that complicated to come up with more improvements to seam-carving: just stack on different energy functions (either forward or current energy), and compute the ideal seam based on the (weighted) sum of them.

Alexa Flash Briefings – No Coding Required – Say Hello to Speakeasy
The more I read about USDT, more it looks like money laundering. These guys take your USD and issue you equivalent tokens you can trade with. As long as a lot of people don't try to encash their tokens everything will be fine.

Also note that if holding USD is the only problem this is supposed to solve, why not just hold USD? Except if you want to bypass your local laws. I buy USDT in country A. Trade BTC for it, then sell BTC for USD in another exchange in country B. This is the only utility and this itself seems illegal.

I had to do a bit of history rewriting not too long ago. On my professional-facing repo I had some projects from back when I was in college where I had done a mixture of commits from both my professional persona and another username. It was only recently that I noticed and so I used git-filter-branch to clear out the commits I had made.

Thankfully it was a long-dormant project.
> a mapping of a String (could also be called a word) of arbitrary length to a fixed length String

Right. It takes a longer sequence of bits and reduces it to a shorter sequence of bits, with a resulting chance for collision.

> since the identity is a virtual concept it replaces the identity with a randomly generated number

It's not replacing anything. Here's another way to think of it. V8 needs this function:

int getHash(Object object) { ... }

Given a reference to some object, it returns a hash code for it, based on the identity of the object. The requirements are:

1. Returned values should be nicely distributed over the number space.

2. If you same object in, you must get the same hash code out. Even if the object is mutated between calls.

This sounds like a reasonable definition of a hash function, right?

If all this function had access to was the object's properties and it had to be pure (couldn't modify anything), it's actually impossible to implement this function. (This, strangely enough, touches on fundamental ideas around mutability, identity, and equality.)

So V8 relaxes the requirement that the function be pure. getHash() then generates a random number for the object, stuffs it in some hidden chunk of memory inside the object (what the linked article is about) and declares by fiat that that number is now the hash code for that object's otherwise-intangible identity.
That's an interesting perspective to hear about. I am curious, do you (as a merchant) have an Amazon rep you can get in touch with about issues? How has that relationship changed (if at all) over the years?
Calling hyperthreads "cores" is a little fake. Also, not being really upfront about the egress pricing vs market price for bandwidth. Especially for the bandwidth charges on egress to AWS direct connect.

If you could somehow manage to make the proof of work tied to discovering copyright infringements (from crawling the web), and have the rewards come from lawsuits/settlements, then maybe it could work? It seems like a stretch for that to be possible, especially considering any rewards would be dependent upon the lengthy legal system.

But judging from the ridiculousness of the diagram in the article, I feel like this is not so well thought out.
I think electronics could work in the US. Lead times are very important. It takes a very long time for a component to arrive from Shenzen. If you have a domestic electronics industry, even a bad one, it's always at a huge advantage - since they're just a phonecall away. If you have an acceptable one, you can have really low inventory, make phones as people buy them, and cut a corner on your competitors that way.
It is not the case that "before about 1975 unemployment was typically under 5%". Especially if you are alluding to the 1970-75 period.

Edit: nor did unemployment go "steadily up" from 1975 to 2008.

Good question. Isn't Valve the highest revenue-per-employee company in the world? There's no reason to sell a money printing machine. Unless MS is blackmailing them by threatening to lock down third party apps/app stores in Windows, which would rob them of their business model.

But why can't you just move from BTC to actual USD in this case? And hold USD until you think BTC is cheap enough to buy again.
Well, think about what it would mean to remove a seam diagonally: the edges of the picture would no longer line up. The only way to avoid this is to always remove a seam along one of the axes at a time.
Marketing is a broad field and disciplines have different involvement/relationships to how work is done. Plus your company situations etc... so broad caveat that this is limited information answer.

I'd be inclined to recommend someone part-time/contract if you have a reasonably narrow or marketing skillets required. Mainly for 1) You'll probably get better rates going direct vs a company that has to layer a margin on-top. 2) If your company grows its easier to bring in a person contributing to your success than if they are contracted to a larger company.

If you need broad marketing skill-sets, then a agency may be better. They can co-ordinate work across the many people within their agency. If you do go a firm/agency I would really recommend being careful you dont get their talent pitching you, then the work is handed to the cheap drone. This is a problem in many agencies.

Most importantly, do you know what marketing work you need?

I agree, this type of solution is 'trendy' and 'innovative', but is not a real solution to the Bay Area's housing problem.

We do not have a space or money problem, we have a legislative one. Building height limits, NIMBYs and other laws affect how many homes are built. We have plenty of space in the sky to build 12+ story buildings for housing, but we don't.

A ground based drone is orders of magnitude simpler than a multirotor. There is nothing magical about multirotors except being the latest fad for tech geeks.

A ground based drone — eg a modified bulldozer — can carry far more plants as cargo, meaning planting a field of a thousand sapling might require one trip where a flying drone will require a thousand trips.

The only catch is access: for a remote region with no trails of any kind it might be difficult for a large vehicle to navigate through the forest. In this case clearing a path for the planting machine might be a lower cost to the environment than the energy required to fly a thousand sorties with flying planters. A ground based drone will also be able to plant more robust saplings, since payload weight is far less of a concern.

I did some off-the-cuff analysis of some random code a couple of years ago and found the traditional ARM constant encoding to be not as good - for that code, at least - as the MIPS-/POWER-style load low/or high business. So if my code is at all representative I'm not surprised they went for MOVW+MOVT in the end: https://news.ycombinator.com/item?id=11607119#11608650

Regarding the 00XY00XY and XY00XY00 forms: I'm going to have to sleep on this, but this is a bit of mystery to me so far. I'm going to have to keep an eye out for those sorts of constants now! Maybe they're actually quite common?? - I suppose this will certainly let you form many kinds of mask useful for SIMD operations.
A lot of people refer to atom and vscode when complaining about the performance of modern text editors and while they are not the only modern text editors by far, they are definitely some of the more popular ones at the moment.

I can definitely say that atom has performance issues. I get lockups and stutters working on small and medium sized files (hundreds to thousands of lines) and it is infuriating. It is unfortunate because there are a lot of great new plugins for these platforms but they consistently cause me all kinds of trouble.

Old school editors(like vim or emacs) or modern IDEs perform much better as text editors nowadays compared to plain modern text editors.

Yeah I don't understand this. How can this possibly work for programs like this:

var s1 = readWholeFile('file.txt')
var s2 = readWholeFile('file.txt')

// now s1 and s2 are different strings, but with the same content
assert(s1 == s2)
assert(s1 is not s2)

var d = {}
d[s1] = 'xyz'
print(d[s2]) # should print xyz.

However if s1 and s2 really have random hash codes how does this work?

Is there a difference between "strings" and "objects" in v8? Mutable objects have one hash codes based on IDENTITY, whereas strings have a different hashing strategy based on VALUE? I didn't see that in the blog post.

This seems to be an abuse of the term "hash code"?

In Python, you can't hash (some) mutable objects:

mylist = []
d = {}
d[mylist] = 1
