> do you have one palace per book?

Yes. Some people chain together small locations that in aggregate serve as a large palace

> Many bullet points per location?

At first I used the "roman room method" which put 10 items per room. Later, I store "memories within the memories" which is like zooming into a single item that itself serves as a mini-palace. For example, maybe Mr Rogers is in a room. I can zoom into him and he could have something on his head, in his mouth, on each hand, etc and he could store an additional 10 ideas.

> Very big memory palaces?

They are places I've been like houses with 5-10 rooms. I tried using the British Museum because it has google street view.

The key to memory is link ideas to what you already know well.

>do you memorise as you read, or do you take notes and learn those?

I've tried both. If it's a "concept book" then I read it once, take short short notes of only 3-5 bullet points per chapter, then memorize those at the end.

With "course/class/do-it" books where you're learning by doing and spending a long time with the book, I paper clip a folded sheet of paper in the book and do it on the fly.

> any guides that you found particularly useful?

I'll share some below. One point to share is that this is a skill (like bike riding). So studying the method (at first) is almost useless. Just try it, learn by doing. Answer your own questions by doing the experiments yourself. Start with memorizing something you actually care about. You will totally suck at first, and rapidly improve. :)

No, it would be the opposite. If people think they have access to privileged information then they will follow their trades, making them profitable even if they are bad trades.

Thanks for the feedback! We're working on improving the onboarding flow. Sorry about the Docker link issue - it should link you to a copy of the environment binary so that you can play around without Docker (no docs for this workflow just yet unfortunately).

It's essentially a Bomberman-inspired game, where you program the agents to play in it and can play against other users' agents. You can try it out without an account by cloning one of the starter kits here: https://github.com/CoderOneHQ/bomberland and following the usage instructions (but you'll need to create an account to use the visualizer and to submit agents).

We recommend the Docker flow, but if you get stuck feel free to reach out to me (Joy) or @thegalah (Matt) on our Discord: https://discord.gg/NkfgvRN

They did imagine it. That's why it works. Even though it's stretched to its limits, most of the traffic on there is IPv4 which dates back to the 80s.
Weird circumstance? It seems like an entirely predictable outcome, and as such it seems like it may very well have been the actual point.

Especially since NFTs confer no actual assets or rights in anyway that matters EXCEPT for in an adjacent speculative market.
I think HTTPS has been oversold. We've had a very myopic focus on men in the middle, which, for sure are a problem, but they aren't the only problem, the first problem, or the last problem in digital security.

HTTPS helps against some attack vectors, but makes you incredibly vulnerable to others. It essentially forces you to blindly trust your software, since you can no longer inspect what is entering and leaving your network. Especially as it's becoming ever more common that our software dials home with opaque "telemetry" that for all we know could contain anything.

HTTPS protects you against the neighbor's 17 year old son with his pringles cantenna and laptop full of scripts, but makes you much more vulnerable from large scale attacks, which become much more viable for those who have the capital to back them.

It's pretty dang weird that EFF has been leading this charge, especially in the wake of Snowden.
No I've been to Belgrade recently and there are no more bombing ruins to speak of. All of that was cleared years ago. In fact there's a lot of new construction happening in the waterfront area.
When you turn it into a binary "we need to stop them from absolutely sharing any privileged information" or all is lost, it's an unsolvable problem.

Alternatively a few achievable steps could make a large improvement:

- Force them to put everything into a trust that they don't have direct control over for the duration of their term vs. allowing them to make trades and disclosing it eventually.

- Have enforced laws on sharing information, and actually
send people to jail a few times a year.

How would crypto help with moving money out of a country if mining is banned?
Gordon is amazing, and it's almost impossible to beat him to an answer for certain types of questions :) I had the chance to meet him a few years back to talk through some new SQL features coming to BigQuery (I'm at Snowflake now). He had a lot of great insights into what could make the product better, and what he thought was missing relative to other OLAP databases.
I know it’s utterly distasteful, but I am fairly amused at the youthful rebellion of defacing a web page in this fashion. Feels very old Internet.

Its an interesting piece, people just reading the comments or commenting on NFTs in general are missing out.

>>[Status symbols] also need alibis, plausible excuses for ownership other than the intentional acquisition of status symbols ... The best alibi for NFTs is that they are an investment ... to cunningly flip later.

So when the market becomes saturated and the ability to flip (aka the alibi) is gone, will the market collapse?
Dr. Lynne Kelley the author of The Memory Code and Memory Craft has it. She uses memory palaces. With aphantasia you still have a hippocampus so thinking about the concept of space to encode info works just the same. :)
Yes, and other people I know don't have the same problem. Making me think that everyone who has this issue is part of some A/B testing [1] bucket for an internal Gmail spam filtering experiment.

These A/B tests are quite common for products like these to test new features, such as a new spam filtering algorithm. Or even test the efficiency of an existing spam filtering algorithm by degrading the experience of a subset of users.

To be clear, I'm assuming by "array" you mean "vdev" not the overall pool, since adding new disks to a pool has always been the normal way to grow a pool. PR was opened by Matthew Ahrens (one of the OpenZFS founding devs) back in June for RAID-Z expansion if you're actually curious. It almost certainly won't hit any stable major releases until next year while everyone kicks the tires, though should be noted ixSystems has a history of pulling new ZFS features into TrueNAS early (they might be more cautious to be ultra careful about this one though). But working code is there, it just adds another capability to the existing [zpool attach] command.

FWIW I honestly don't think growing an array vs adding to a pool is actually that interesting given the modern state of drives and how capacity growth has lined up with data growth across the spectrum. At the consumer/soho/small business scale growth curves for storage blew past data needs a while ago, so by the time somebody needs more storage the drives are old and it makes more sense to just replace them with much bigger ones (which ZFS supports fine, replace all the drives in an array one by one then it'll expand), or small drives will be so much cheaper that just adding another set to the pool makes sense. Much bigger then that and people aren't going to be doing array expansion ever anyway. Still, cool to see that one checked off the list, and if the functionality ultimately enables generalization to RAID-Z type conversion or better rebalancing that'd be very interesting.

>Then same question but with a disk which is not the same size that the rest of the array.

Don't do that simple as that? There isn't any great way to handle that with full performance and redundancy, and any possible value seems way way too niche to be worth bothering with. Although again if you want to add uneven vdevs (single or multidisks) to a pool you can always do that if you want.

Edit: One other practical consideration I've always had regarding expansion, adding disks and so on, is that the troublesome brute force method to me is an excuse to promote good habits and practices most of us are very lazy about in general. Having to tear down a pool and restore to get best performance and flexibility out of adding a bunch of disks is certainly a pain. But we should be able to do this at any time anyway, we should be semi-regularly testing that it works, and we do all do that testing right? Right? OK probably not, plenty of people aren't in the habit which is why automation is so important. But even if ZFS gained full perfect flexibility, I still think I wouldn't use it in general because I think the exercise of making sure that yes I can do a full restore and everything is working at least once every few years is so valuable.
Yeah, the spousal loophole is a hard one. Having an elected position restricting a spouse isn't right, but the fact that money can flow freely within a marriage basically annihilates any restrictions.

Other non-marital transactions can be controlled - that's the basis of half the tax system in every country. The moment money leaves a household or arrives in a household, there are laws about the transaction. But within a household? All bets are off.

In a vacuous sense, but in practice you almost always use asynchronous code to achieve concurrency.

The canonical Microsoft tutorial on async spends about half its time talking about hiw to make your code concurrent to take advantage of async.

This. This 100%. I don’t think my nerd cred is in any danger. I regularly write kernel code, bare metal code, assembly, etc. I know how to computer.

But the older I get, the more I find I’m just happier in the Apple ecosystem. I don’t want to fiddle with X11 settings or tons of dot files. I just want to open my computer and hack on the shit that interests me. There’s things about Apple that annoy me, but the same can be said for Android, Windows, any of the free *nixes, etc.

Every platform and ecosystem has trade offs and it’s fine to just use what you want to use. Personally I’ve got Apple laptop, phone and tablet, a Windows desktop for games, several RPis running various Linux distros, and a Proxmox server running VMs for infrastructure and tinkering. None of that makes my farts smell better than anyone else.

… except for those nasty Emacs users of course :P
There is no technology that monitors trades of friends or family outside the US banking system.

Why else are there thousands of companies based in the Cayman Islands? It is to obscure the identity of the traders.
Good point. Maybe all that’s needed is for better prosecution of insider trading for these guys?

Of course the problem is the power they have to resist or meddle in any prosecution efforts… that’s always the problem with holding the powerful to account, I guess.

Is Stage Production the Software Engineering Metaphor I've Been Looking For?
I am a mechanical engineer by training. But a software developer of many years. The majority of the work I have done has been in the bridge space where real world gadgets and software meet. I have worked with companies that have tangible products with all of the manufacturing and engineering discipline that goes along with then. Invariably, these companies want to treat software efforts the same as they do the rest of their engineering disciplines. Why wouldn't they? After all, we call ourselves engineers too.

I have looked far and wide for analogs to help them understand what's different. I have often seen the collaborative production that goes into movie production as similar to that of software development. We tell stories. There's creativity. Rewrites. Lots of mundane behind the scenes work. Those individuals that make or break the execution of the effort. The problem with movie production, is that once the movie is done, it's done. Which is similar to actual mechanical widget production. The product evolves very little once it's "published."

Stage production is similar to the movie making model. But you have to expend ongoing work to keep the production alive. Sure, there's an up front investment that is more creative in nature to producing the opening night show. But even after the show touches down, you have to continue to be creative to keep it running. You have to pay the ongoing bills. Deal with different actors who come and go. Changing social issues mean tuning the play to keep it fresh and relevant. Does this work as a metaphor?

China seems to be hell bent on exiting the global speculative markets. Can the stock markets absorb this shock?
Pollution is also a huge problem in China. While China would like to still keep its electricity cheap, especially in the hinterland where people can’t really afford higher prices (and otherwise would resort to direct coal use for heating), crypto miners taking advantage of the cheap rates in a way that government didn’t intend.
In the simplest way, not unlike Windows Update: snapshot filesystem, start filesystem transaction, unzip changed binary files, check new files integrity, end transaction.

Indeed, Apple used to distribute patches this way in the past.

You also could ship a list of updated system files hashes, compare to the installed files and just download the changed ones, like rsync.

Better than shipping a whole new disk image every small update they do.
I’m not so sure it’s complete bs. Ive worked with Steph on a dozen design projects through his brand. Typically I’m actually only interfacing with his team so I’ve only met him personally a few times and only for a few minutes. The last project I got to meet him again at the roll out. I pitched the idea of creating NFTs for his foundation to the guy running his foundation. The guy was totally interested. A few seconds later Steph walked by (and wasn’t being mobbed by everyone around) and the guy told Steph “this guys talking about NFTs” … Steph did a triple take and eyes wide and seemed genuinely juiced to talk about it. Moments later he got mobbed by kids for autographs and that was it.

Not saying NFTs are not a sham, just that I was super surprised at how interested he seemed in the subject.
> Could they firewall the entire bootstrap IP list for Bitcoin mining?

I mean, yes that would be one way. But apart from that, they don't need to find every last one. Nobody cares about a miner making $0.5 per day on their GPU. The target is the big mining farms drawing multiple megawatts of electricity and you can just ask the power company for the address of anyone using that much electricity. There can't be _that_ many of them, so just visit them all and see if they are running a legit power-intensive business like a metal foundry or if it is a crypto mining farm.

If you think anti-cryptocurrency sentiment on HN "appeared suddenly a few months ago" you really haven't been paying attention. People have been whining that HN is so so negative about cryptocurrencies for years.
Look at Facebook stocks, they don't seem to be "kneecaped" at all. My theory is that tracking is a nice to have but not necessary to make huge amounts of money on ads. They lost a few percent of value over this, a huge hit to investors but even with that they are still one of the tech giants with more money than they know what to do with.

AWS Lambda for beginners: overcoming the most common challenges
async/await is not for CPU-intensive parallelism. I think that's pretty much stated in the .NET docs. That's why Parallel Compute APIs like Parallel.ForEeach/For are not async. Their purpose is to enable non-blocking waits for IO, as well as to do stuff like animation on UI where you might want to execute procedural code over a larger timeframe.

You’re not correct on a number of fronts here.

ZFS is not tied to the memory allocator in Solaris, I’m very unclear how you could have made that mistake.

128bits might feel wasteful, but you’re likely never going to have the problems FAT32 has had- it’s designed for the next 100 years- which has drawbacks but prevent the kinds of ugly hacks that NTFS has gone through to maintain forward compatibility (rolling on disk upgrade).

And yes, the 1G per TB is for the in memory block map, which is a requirement for deduplucation on the default block size.
