> But they don't have stable qubits and so they can't run Shor's algorithm. So D-Wave's machines are similar to AMD's and NVIDIA's

I don't see what's "unstable" about a D-Wave qubit; it has an input bias and it has biases about the qubits it is connected to, which you can tune, and quantum coherence is held for long enough for there to provably be tunnelling effects involved in the process of settling down to a ground state.

I think there's a massive lack of understanding about quantum computing that includes a huge bias against these quantum annealers, and it's baffling to me - why wouldn't someone want to see this process work? Certainly their early customers and developers see something there that you might not.

Everyone's obsessed about Shor's algorithm, but it's not the most interesting thing in the world, is it? I mean, do you really want all current encryption to be rendered worthless by whoever owns it? I'm happier to see things go in the direction of solving optimization problems for traffic flow and scheduling instead of military uses, for once.

I'm a paying customer of Trustle, for a few months now, and absolutely love the service. I don't know the founders, I just work with one coach and couldn't recommend her highly enough. I proselytize to friends and family, but they never seem to understand and just give me blank stares as I explain how much she helps. Maybe I do a poor job pitching, but I don't think that's it.

If I had to guess, I think most people prefer to be reactive, not just with children, but in every facet of life. Whereas other people (especially on HN) are instinctively proactive and are always looking for new ways to invest in the future. The reactive people don't seem to understand why I need the help of a professional when my infant child seems calm and grounded. Proactive people understand immediately; they get that it's an investment.

When I signed up, I didn't even know what Trustle was planning to offer. They said they do "parent coaching". Huh? I just knew for $x/month if I could bounce ideas off a professional it would be more than worth it. Fast forward a few weeks and I quickly learned to trust my coach's advice more than any pediatrician, day care worker or family member. The reasons are long and detailed, but suffice to say I'm a serious fan.

I've spoken to my coach a couple of times about tough situations, like sleep problems (she was impossibly helpful), but mostly I see value in our discussions about learning, discipline, philosophy, independence, etc. I've come to love her pragmatic, balanced and evidenced-based approach.
There's nothing wrong with trusted computing as a technology. The problem is users don't own the keys, fundamentally antagonistic companies and government agencies do. It'd be great if we could install our keys in the system and use the technology to make sure only software we have signed ever executes.

The problem with trusted computing is in how Apple, for example, uses it to prevent users from running software they don't like on their own phones. The problem is the fact that Apple is in control instead of the user, not the technology it uses to maintain the control.
The compositor would have to talk to the virtual GPU driver to allocate additional surfaces on the host and make them available to the guest.

The next best alternative currently is looking glass[0]. Linux host with GPU1, Windows guest with GPU2 via pass-through and then copy the framebuffer from the guest to the host.

Oh, no doubt, and I bet you could get someone from any of the current QC companies to go hog wild with ideas over a beer or two, but in practical reality what matters is execution and manufacturing - something that Honeywell, Google, et. al. have been scant on but seems to be core to what D-Wave is doing.

Maybe I misunderstood it but why would you create a react app for writing Hello world. In Javascript you can do that in one line 'document.writeln("Hello world")'

That's equivalent of installing Laravel first just to write Hello world in PHP and saying look how big my vendor folder is.

> It proved that they could use a quantum computer to compute something that would be infeasible for a classical computer to solve in a reasonable time frame.

Yeah, but they were basically computing noise, and it's bloody difficult to say that the ability to do that is meaningful enough to have claimed "supremacy" already. It's a huge premature celebration for a team that has had incredible difficulty trying to scale up beyond a tiny number of noisy qubits; like, good for them, but the purpose of this effort really seems to be to make for good water-cooler conversation among the Google execs than it is to actually do useful science.
I think it's an unambiguous ethical failure that Bitcoin's traffic isn't opportunistically encrypted. As protocol developers we have an obligation to provide for users at least a basic level of protection and because of known threats on the modern internet that protection almost always needs to include encryption.

In particular, due to material published by Edward Snowden we know for a fact that nation state attackers have exploited this weakness to compromise the privacy of Bitcoin users, but even if before we knew that-- it's a reasonable assumption for any protocol which handles private information.

Unfortunately, Erik Voskuil (maintainer of "libbitcoin", a bitcoin node implementation used by virtually no one) has aggressively argued against any implementation of encryption with arguments that it would create a false sense of security and ultimately convert Bitcoin to a permissioned network. (e.g. https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2016... and the surrounding thread; note that this was in _2016_. The same fruitless discussion repeated in subsequent years.)

I don't think any of Bitcoin's regular contributors have found his arguments persuasive in the slightest. Personally, I believe the arguments are outright incoherent. Never the less, these arguments are repeated every time its discussed.

After years of vicious abuse many Bitcoin contributors simply no longer have sufficient will remaining to proceed in the face of even more drama. It would be perfectly possible for Bitcoin Core to deploy encryption and for software like libbitcoin to not do so-- it doesn't have to be universally supported... but even so, the drama remains and no one wants to deal with it.

As a result little progress has been made in bringing the encryption functionality to completion and users are left needlessly exposed as a result.
It's only an awkward phrase because of what it reminds you of; maybe stop thinking about the bogeyman so much.

With server side font rendering all but forgotten among other things, any modern app will struggle over a low bandwidth link well.

Element manipulation is normally slow because of layout computations, but explicit transforms remove the element from the layout flow (it doesn't affect nor get affected by the sizing and content of other elements), cutting nearly all of that cost. Also, in most browsers explicit transforms get computed on the GPU.

So for this type of case there isn't nearly as much going on between the DOM and the raw graphics code as you might think
That's... slightly better? I think? Honestly SGX is complicated enough that I'm not entirely sure I have this straight. Am I correct in thinking that:

1. A user-programmable MSR would allow the device owner to falsify the attestation of enclave initialization (when using their own keys).

2. The ME (and other firmware) would still not be replaceable or owner controllable.

3. Due to 2, enclave compromise would have to be premeditated. That is, once an enclave is up and running IIUC it can (potentially) use MRENCLAVE to derive the sealing key. Without control of the ME that enclave would be unbreachable, correct?

So realistically, to maintain control of code running on my device I would have to set my own SGX keys and configure my system to actively compromise all enclaves at launch. From a security standpoint, there's still a black box (the ME) with super-root that could be compromised by attackers that I can't inspect, modify, or disable. And from a political standpoint, there's still a tragedy of the commons regarding DRM if the majority of providers decide to require SGX with Intel root keys as a condition of service.

Have I misunderstood anything?

(While responding, I stumbled across an interesting paper regarding using SGX to protect malware against researchers: https://arxiv.org/abs/1902.03256)

Edit: It appears I was overly optimistic - playback of 4k BluRay already requires Intel SGX. (https://old.reddit.com/r/Amd/comments/bw0cwq/will_ryzen_3rd_...)
TL;DR - If you are a hard-working entrepreneur, let this be a reminder that we're prepared to abandon you when the global economy is in recession. We expect you'll pay it forward by treating your hard-working employees the same way. If you follow our lead, your company may survive long enough to raise money from our firm in the future. This thought leadership blog post is an example of our founder-friendly approach, and demonstrates how we add value to our portfolio companies.

Objectively speaking the advice is prudent. Still, someone should tell their marketing team that this piece is seriously off-brand. It signals to entrepreneurs that the firm's messaging around the notion that "People Build Companies" is not to be taken seriously.

In snes Zelda, the dungeons were designed such if only you had an item, it would be so much easier. Like a rope to clear ledges vs having to go all the way around.

It is said that this teaches without words.. makes players long for an item before they have it and when they get it, they already know why it exists and how it is used.

One advantage of going slower with students and helping them with things like (oh that didn't work because Microsoft Word changed your quotes), is they build an understanding of the tools.

Git is a good example. I have so many CS student friends who talk about how annoying their teacher is for making them use git, and how they don't see any point in it. From their perspective I totally understand. As soon as they realize like (oh I needed code I deleted, or oh I need to merge two people's code) will git start to actually make sense.
You make a good point, a good UBI pilot would incorporate the necessary tax increases.

But that's not what this study did. Crucially, the disincentive to create only applies to low income earners. Under, UBI everyone pays the taxes and thus everyone gets that disincentive to work. If we want to see what UBI would do, we should actually do UBI.
I have noticed that a lot of people treat work as a social event. They spent a significant amount of their day shooting the shit. As an introvert who can't stand smalltalk, I don't. I think 40 hours or more makes sense for employees who spend half of their day chatting or surfing the internet. When I'm at work, I am working. I still do more than 40 hours, but I'm not sure if it's sustainable. I was recently asked to increase to a minimum 48 hour workweek and turned it down because I know it would upset my work life balance and not increase my output.
If many people are doing roughly the same "thing" then surely it makes sense to automate that "thing". It's much like how we don't build and develop software for every business process: we look for an existing solution that is general enough to fit our requirements (usually Excel).

Have you ever written a program that incorrectly looped forever? or one that deadlocked? or had any such other liveness bugs? I can't speak for you, but I certainly have, and, if the questions on stackoverflow are to be considered representative of typical humans, then it seems most other programmers have also done this at some point
in their lives.

In general, human answers to halting problems have no guarantees of soundness or completeness, and can't be guaranteed to be correct unless presented as some kind of proof in some kind of logic.

Then, if a human can use some logic system to guarantee that a particular program halts, then a turing machine could also trivially solve this problem, by simply enumerating and verifying the possible proofs of program in the logic system. This proof strategy has further benefits beyond ad-hoc human reasoning, in that it is guaranteed to eventually find the proof if it exists.

Ethos Capital is comprised of ex ICANN staff, and have tight commercials relationships with people actively running PIR.

Coincidentely the price caps disappear by ICANN ruling and suddenly Ethos Capital is formed to buy a property from PIR - an organisation that was specifically set up to care for .org.

You seem to be confused about this whole situation. We arent talking about a registrar - we are talking about the registry. There is no market pressure affecting the price of a .org from the registry, so there is no "price cap". PIR is an NGO and they are happily cash-positive, so there is no direct reason for them to increase the prices.

It is only in Ethos interests that the price would be increased. Its literally a license to print money. They have even just announced that they would cap price increases to 10% a year for 8 years. That means that within 8 years the price would be over 2x what it is now, and after that, they can set it to whatever they like.

I dont get your rant about NGOs pissing money away. If you mean PIR, I already mentioned that they are happily cash-positive, and certainly waste money on stuff outside their remit.

No-one really cares about $10 vs $15 - which is kind of the whole point. This whole situation has come into existence for Ethos to be able to make a "generous-looking" 1 billion investment with guaranteed return within 6-7 years without even increasing the number of domains sold.

So yeah, its clearly corruption. There is no viable reason for PIR to sell .org. If they want 1 billion they should just raise the price caps 10% a year and in 6-7 years they will have it by doing nothing, and still have .org.
Agree to disagree then. X is shit. I remember first reading that chapter in 1998, and it resonated then just as well as it does now. X is shit. It is the weirdest abstraction of network "transparency" which inevitably manages to require state on both ends of the network connection -- it isn't robust. How well does your X session do when there is a network hiccup?

The protocol is round-trip heavy. Even with xcb, X clients need to make a tremendous number of round-trips, especially early on. There have been mitigations for X for low bandwidth links, but X networking has never been usable on high latency links. Ever forward X on an airplane? I pity you.

The drawing model of X is an antiquated relic. Server side rendering is pretty much useless, such that X has basically become a sort of bastardized inefficient VNC.

There's a reason no widely used screen remoting or thin-client system uses the X design. It was a poor idea then, and it is still deficient today.
Why is there a focus on people working at all? I thought one of the reasons UBI was so interesting is that people who are stupid, lazy, incompetent or just too obnoxious to work in customer service can stay at home and out of my way.
How would you install cams at general aviation terminals? It's not like you could just walk into them.

There is no parking there(allowed). It's all gated and guarded.
>Compare this to have a service that edits (let say an HAProxy) configuration and populates it with IP addresses.

Just edit the hosts file? If you have access to machines that run your code and can edit configuration, and also don't want the downsides of resolvers (pull-based instead of push-based updates, TTLs), DNS still seems like a better idea than some new stacks, plus you can push hosts files easily via ssh/ansible/basically any configuration management software

EDIT: The only issue I see with DNS as service discovery is that you can't specify ports. But usually software should use standard ports for their uses and that's never been a problem in my experience.

What if it enables those same people to take the time off work they need to treat their depression? Getting help takes enormous energy that a depressed person likely doesn't have if they're spending all their energy just trying to survive.

> First, peoples’ satisfaction is primarily influenced by the visibility of the inequities immediately around them.

I agree. What follows from that? Do we let some people live in the 21st century but hide their life style from the rest so we can keep them happy at a level that we can more easily automate?

And sure, it's not going to reverse necessarily (though it will to some degree, because we can't "automate" the 2020 economy). My point is that people aren't satisfied with no progress. Wanting to change things for the better seems to be a very natural part of humanity, making plans that don't account for that drive doesn't seem wise.
