Postgres and Sql Server are both similar generations of database architecture, so I would expect them to perform similarly in some aggregate sense. For Postgres, I would argue that the major architectural limitations that impact relative performance are in three areas:

- The storage engine architecture is obsolete and highly suboptimal. It has no way to accommodate modern high-density or high-bandwidth storage, both of which are the norm now, nor is it possible to implement any of the (very successful) I/O schedule optimization concepts that have emerged in recent years. The net effect is a gross underutilization of the capabilities of modern storage hardware.

- The internal page layout and table architecture in Postgres is a textbook classic but not appropriate for most workloads on modern hardware. Modern page engines need great performance across diverse categories of workloads and data models -- we use databases for a lot more than accounting systems these days -- while also being amenable to aggressive use of hardware optimization like SIMD. Thinking in terms of "row-oriented" and "column-oriented" is a false dichotomy; optimized page engines commonly have many elements of both but are not identifiable as pure expressions of either nor even a simple hybrid (e.g. PAX layouts). This is one of the easiest changes to backport into old database architectures.

- Indexing in some modern systems have been completely reimagined to great effect. Tables are effectively index-organized with no secondary indexing structures but without loss of high query selectivity across diverse columns; there is a separation of the concerns regarding fast search and key constraint enforcement; major increases in index write throughput concurrent with major decreases in storage and memory footprint (no B-tree bloat). For small tables, this optimization has no effect and may even be a mild pessimization depending on the workload. As tables become larger the performance starts to diverge greatly, becoming multiple orders of magnitude faster. The Postgres architecture can't be modified to support this.

If you built a database engine that was approximately state-of-the-art in these three areas, I would expect a 100x difference in performance relative to Postgres for many large data model workloads using server hardware like an AWS i3en.24xlarge. Obviously building such a database would be a hell of a lot of work, it isn't something you can reasonably do for fun on nights and weekends.
In-the-matress savings are money that is not invested, such as cash stuffed in a matress.

This is the opposite of soaking the rich. The well-off generally have a very large proportion of their wealth invested in productive economic activities, with returns well above inflation.
That only fixes the Internet part, but not the rest of the infrastructure issues which need a lot of investment to break the vicious cycle of neglected infrastructure, people moving and the tax base to fund the maintenance of the infrastructure eroding as a consequence.

In the early 80s with high inflation and therefore high mortgage rates, the first years of mortgage payments would be a relatively high percentage of income: it's very front-loaded. However, the debt owed quickly gets deflated away, so over the span of 25 years you're actually paying a much lower percentage of your real income. To take it to the extreme, if inflation was approaching infinity, and mortgage rates were 2% + inflation, your first payment would be 99.9% of the value of the loan, and all subsequent payments would be essentially 0% of your nominal income. Add to that fact that a downpayment went a lot further (if you saved to 50% of your median income, that was 20% down payment of median house), and affordability back even in the worst of the early 80s, while not great, was better than now.
I'm not an expert but I am writing a game using DOD and ECS, in Java, for Android, and it's a 2D game so performance is not an utmost concern. I can say that using the ECS pattern and being data-driven has absolutely saved my bacon and made the dev process so much easier. Tricky things, like adding new enemy or elevator behavior, have turned out to be not so tricky when I get to the implementation bit, because the ECS makes things orthogonal when they would be tangled up with each other in a strictly OO model.

With all due respect, I don’t pick up on this at all. I get the distinct impression that everyone realizes how much we’re getting screwed but has a learned helplessness that we are no match for the corruption of our corporate political overlords.

Protest over $150/mo cellphone plans? We don’t even do that over 35% growth in housing prices year over year over year.
if they normalized the budget such that extra things not purchased in previous years is not taken into account, it could be used as a personal inflation measure. Normalizing the budget means you remove any life-style creep that gets in.

This way, you can look at your salary, and determine whether you're gaining income above your own inflation, or not.
There's a channel on Youtube called Jimmy Darts, he gives out $500 to random people or whoever he deems they are poor. Lot of silly little tasks but you know I enjoy watching the content and people who really need the money get it.

Go read the comment that begins "Top 10 maintainer here". Not even a shrug.
Under federal law, when you get your credit card bill, the bank is required to include a breakdown of, for example, how long you have to pay if you only make the minimum payment, and how much your total payments will be if you only make the minimum payment.

We need something similar and conspicuous for mortgages. Let people really see/feel the interest.

Another way I’ve seen it phrased is in terms of buying power, and I think that can be effective. I’m ball parking some numbers here, but I think I saw something along the lines of, for the same monthly payment you can buy a $275,000 house with 5% interest or a $350,000 house at 3% interest. I think that drives the point a bit

The monthly payment is often used because people are comparing the cost to rent, or the monthly cost of their current mortgage.
> Walking up to some children you do not know and offering to take them to a secondary location

heh yeah and some kids are very well trained to defend themselves. An offer like that to a larger than average pre-teen or teen may result in way more than you bargained for. If they see you as a threat and the flight/fight coin toss lands on fight, well, you're in for a ride.
I’m curious why you would do it this way vs publishing to SNS and having that fan out to multiple queues where each consumer can listen for the things it needs to work on (as mentioned in the original article.)
I my complaint that they are calling this atx, when the only thing remotely ATX about it is being designed to work with the atx motherboard power connector.

This in no way meets the atx form factor for power supplies, neither the original, nor the 12V version. Like I could forgive it if it failed to be a rectangular prism in favor of having more open space, as long as it had a frame with proper mounting points.

And I could also forgive it if they went with the rectangle, but far shorter than the official 140mm depth (that has always been mandatory per intel specs), given that the market already accommodates non-conforming lengths, and this could be made to not require the bottom of case mounting holes, allowing for absurdly short lengths.

But the photos show none of that, and just a fully custom form factor, without any apparent mounting mechanism.

Conceptually it is still a terrible idea to have multiple consumers (By multiple consumers I mean things doing different actions on a message, not concurrent consumers doing the same action) on a single queue. Why overload a queue like that for 2 different actions when one can fan out on an action to 2 queues with SNS? Then your consumer does not have to determine if the message is for them or not. Visibility timeouts are for concurrency/errors by a single action. Yes you could hijack it and have 2 consumers act on one message and do different things but that is confusing and no benefit over just having 2 queues

> You could say "ok, disband the regulation and let them compete" but many times that just leads to the total collapse of certain domestic industries because they simply can't compete with US capital.

What’s wrong with this if it leads to lower costs for consumers and better service?
Well given that a union at least initially isn't part of the formal company structures almost by definition then there needs to be some process of recognition that yes this organisation that claims to represent my employees does in fact represent my employees.

But in this case, the union is already established and recognized by the acquired employer. MS (or any other acquiring entity) shouldn’t be allowed to ignore an existing employer-labor relationship. If that were true, any time a company unionized, the stockholders could just continually buy itself with another shell company and terminate the union relationship.
The author, Bret Victor, put his money where is mouth was and founded a tangible computing organization named Dynamic Land[0] that is funded in part by the research organization led by Alan Kay.

Dynamic Land might be the most interesting approach to collaborative computing in person that I’ve seen to date.

Bret designed the system, wrote the operating system, and the libraries used to interact with the OS via physical objects. It’s awesome.

It would significantly reduce the size and reach of these entities. There would be no global financial system, and that would be a Good Thing (tm).
I'm not sure what it would even mean for a union to "just show up".

A union is by definition a group of employees. I guess you're talking about, maybe, representatives of a national union coming to an employer without there first being a union vote within...?

That's not remotely like what's being discussed here. What this situation is, and what's being talked about, are a union formed within the company (whether or not it's affiliated with a national union) and whether the employer has to recognize it and bargain collectively.

I can't even fathom the idea of a union with no members at a given company or organization "just showing up" and trying to get the management to bargain with them on their workers' behalf. It's just utterly nonsensical.

Imo, the idea that it would be great to type on a glass touch screen is Steve Jobs biggest and most long-lasting misstep.

Overall I think it's interesting and bizarre that both modern technology and visions of the future have totally sacrificed tactility. It seemed to be all about removing the real world: tactile interfaces are old fashioned, in the future everything works in a way that has minimal connection to reality, e.g. a Minority Report style UI, and so obviously is ethereal and cannot be touched. It makes me wonder why we had that ideal in the first place, and whether that ideal shaped technology or vice versa. Why did we fantasise about losing tactility?

Something I've also noticed is that we almost seem to be unable to imagine a programmable tactile interface, even in science fiction. I guess humans wanted "something extra/futuristic/other-worldly", and that meant having things be unlike anything else in the world, which as the author points out, means something without tactility.

Studies about this (you didn’t even know that existed, did you?). Well,
there is one, it’s quite serious–run by a General, bright guy. I said,
“have you heard about geoengineering?” and he smiled–seraphically–and he
said, “Mmm. Yes. Your question?”

I think people are wrong about what a degree proves.

Sure, it's no 100% guarantee, but it should at least mean you're familiar with the domain enough to find the answers you need.

You said yourself it entails loss of sanity and time - agreed, completing one shows discipline, character, time management skills and enough sanity that you can afford to lose some. Again, it doesn't mean people without a degree don't have these things (self-education can require some of them even more), but that's one way to demonstrate them.

Finally, there's different degrees, mines are from MIMUW so they do prove quite a lot.
It is true that if you need energy density then you want to carry fuel and not use batteries, although whether biofuel makes a good choice I'm dubious about.

'course if you're just driving a hundred miles to see Aunt Tilly, and then fifty more to see Grandma, and then a hundred more to see your old friend from high school, well, those people all got electricity, and as we saw the EV doesn't care that it's not that premium Supercharger electricity, it's all the same if you can wait. So stay the night.

Long distance wilderness trips are both (a) not something most people ever do, so we are not talking about a mass market product here and (b) not well suited to the typical private motor vehicle of today. Who is maintaining roads across the wilderness that so few people use there's no gas station ?

I didn't ask who built them 'cos that'll be the US Government or a State Government, both huge fans of building sexy new projects. But to drive on it a decade later it needs maintenance, which isn't sexy new infrastructure and I'm guessing if there's no gas stations there's no road repair budget. Which means now you need an off-roader, maybe a pretty serious one, or running out of fuel will be the very least of your problems.

Hey there HN, I’ve been working on a prototype over the past day or so that I’m calling MemLink.

The idea is that MemLink enables you to put content on the web with zero friction - no hosting, no deploying, no storing. You author the content, and it simply exists such as any other content asset that you could share.

Very much still rough around the edges. The editor supports dragging the blocks to reorder. Not all of the block types are hooked up yet. There is a custom shorthand syntax to each block metadata value to adjust settings like theming, positioning, and size. The plan is to polish up the authoring experience and abstract away the shorthand for UI controls.

Some issue seems to be:

1) distribution/lack of update mechanism. If you edit your site and someone has an old link, they don’t just get the update.

2) the links are ugly - works great with url shortening services though

3) there’s a size limit to the query param. Working on some dynamic data blocks that would allow you to pull content from other places such as a google sheet or bucket.

Any ideas or suggestions? Please let me know.

Thanks for checking it out!

I'm in the same boat. I don't see "position in hierarchy" as a "trait". The second biggest indicator seemed to be getting income from property (land, investments, etc.) vs. labor. Looking up the dictionary definition of trait seems to define it as one's distinguishing qualities, especially those of personal character. The author seems to have expanded this, and ends up with what is essentially a tautology. Being in a high-income role is the greatest predictor of income.

However, if we're going with the author's definition, then I'm saying the trait most associated with income is "unicorn startup founder".

Capitalism begins to break down when the primary driver of purchasing power is availability of debt. Long term debt is particularly antithetical to the efficiencies promoted by a free market.

Add on the fact that a quasi-government body is the primary provider of that debt and not just through the central banking system but in many cases direct to consumers.
That is not at all a stretch and is slightly offensive that you used the word “stretch” here given what that word is supposed to mean. This is a perfectly valid concern where many people will be pressured into complying.
The question should be, can we have a device with a programmable real-time tactile environment?
Is there any research into causing flat surfaces to simulate a bump while still remaining flat?

It should be "viewBox" (with uppercase "B"):

> Especially in our age it's a life or death skills to have.

I'm not so sure. Many critical thinkers end their life with suicide or end up in mental asylum. It's easier to be a sheep for sure.

The reason for that is of course the fact that critical thinking allows you to see and ponder how f'ed up everything is. It is a dangerous road.
> The major sense I get from Canadians whenever I arrive back is an enormous sense of financial illiteracy.

Completely false. Ask any Canadian how they feel about their internet or mobile phone bill and they will tell you they're being ripped off. We have been battling Rogers and Bell for decades, they have too much money and influence at this point.
You’re forgetting about inflation here. Sure you’re paying 300k of interest for a 400k house at 5%, but your mortgage payement keeps decreasing in real terms.
I guess we can debate the semantics of it because it is technically possible. But it is terrible design to have a SQS to many different consumers. If someone did that I would reject it on review. In any proper usage of SQS it is many to one.

the only audio oriented comment system that i appreciate was the one from soundcloud

you select the exact time, and you put your comment

everyone listening to that music could see what people say about that very specific moment, as they listen

encouraging podcast creators to time their podcast would allow platforms to offer precise comment system that users can consume and contribute to consistently

but nobody cares, because the people who build the platforms are not users, it's not built organically, therefore they don't understand these kind of special things
You're missing the point. It's too easy for the majority to support taxing the minority over anything like this, cause it's no skin off their back. [Not to mention there are already laws pretty much everywhere restricting smoking to places where secondhand smoke isn't an issue- people can smoke at home you know. If you are worried about air quality, then driving in the city should be taxed, but it wouldn't be b/c the majority does it regularly]
1) the slowness of many society's willingness to update their ideas about geocentrism (or other astronomical phenomena) was not that they didn't like admitting they were wrong, but rather that it didn't matter much. Many societies had very accurate ideas about, say, the patterns of tides, or which plants were poisonous. It wasn't that they were so resistant to admitting they were wrong, it was that geocentrism mattered so little.

2) I have never read a single economist's take on inequality that says that "...all is fair with the distribution of income." Perhaps there is such an economist out there, but every economist (neoclassical or otherwise) that I have ever read on the subject, admits readily that all is not fair. They may in some cases think that the cure could be worse than the disease, but all major economists of whom I am aware admit that there are unfair aspects to inequality.

I find Tilt Five[0] to be 100x more interesting than Dynamic Land. They don't serve entirely the same purpose, but I think it illustrates the difference between clinging to the past (Dynamic Land) and embracing a digital future (Tilt Five). Both solutions are powered by projectors and sensors, but Tilt Five pushes the envelope a lot further than Dynamic Land.
