> The other problem is really with consumers.

Nobody ever wants to admit that they make bad choices, but this is the most important explanation for why a lot of stuff sucks. If people were willing to pay more for a reliable refrigerator, that's what would get made. In empirical fact, their actual priority is cheapness, so that's what they get.
> it looks like today's fridges are _orders of magnitude_ more efficient to run than those from about 15-20 years ago

15-20 year old fridges are about 35% less energy efficient than the best modern fridges, not 100x. We just haven't made that much progress in refrigerants, compressors, nor insulation.

It looks like very efficient fridges today use about 400kWh per year. Those are the best (not the average).

In the late 90s, the overall average (not best) figure was ~850 kWh/yr and from the early 2000s (20 years ago), it was ~550kWh/yr.

A 15-20 year old average fridge is about 35% less energy efficient (550/400 - 1) than the best modern fridges.

> Universal back and forward buttons

I didn't realize people actually wanted this! I thought it was just a thoughtless default from hardware manufacturers. Every time I activate back or forward via a special mouse button (or via gestures!), it's an annoying mistake.

I would much rather have (and do have) next/prev tab buttons than browser back and forward!

I'll second LinearMouse, though! It's nice that there's a free solution for this now. Apple seems to periodically break third-party tools that fix their mouse acceleration problems.
> What is their moat?

That's only a useful question if you're an entrepreneur trying to answer the question of "How do I get in on this game?" The question currently being asked is closer to "Is it a problem for society that so many players are in on this game?"

If every big business is just a moat and/or backdoor for banking, that might be indicative of a problem.
Fantastic work Rapawel! As someone who manages multiple remote Linux servers, I can see the immediate value in Cryptreboot: The practicality of providing the passphrase before rebooting instead of after, is an innovative solution that addresses a significant inconvenience in headless setups. Your tool seems lika a solid step towards mitigating potential security risks caused by outdated kernels.
I ran away from Twitter because of Musk but I will (maybe) go back because of your point.

I agree that people value different things but I wouldn’t say information about brand reliability is widely available. I have a consumer reports membership for checking that kind of thing simply because all of the info out there is mostly blogspam and fake review sites.

Information from reputable sources on large appliance purchases is incredibly hard to find since most people don’t buy appliances often, so even consumers used to doing online research will be hard pressed to know which sites to trust. I know that I wouldn’t have a clue.

If there is a place besides consumer reports, which is a paid service, where you can. Heck these things I would be very interested in hearing about it.
The article/webpage is a nice walk-through for the uninitiated. Half the challenge of doing matrix calculus is remembering the dimension of the object you are dealing with (scalar, vector, matrix, higher-dim tensor).

Ultimately, the point of using matrix calculus (or matrices in general) is not just concision of notation but also understanding that matrices are operators acting on members of some spaces, i.e. vectors. It is this higher level abstraction that makes matrices powerful.

For people who are familiar with the concepts but need a concise refresher, the Wikipedia page serves well:

> Schools should aim to maximize learning for every child, irrespective of their starting point or their parents' resources.

Lets say you have two kids at opposite ends of the natural talent spectrum and you have $30,000 per year to spend on educating them. Do you spend $15k on each knowing that you'll get very unequal results? Or do you spend the bulk of they money on the one that needs the most help at the expense of the one who has the most natural talent?

Schools are making these types of decisions all the time. The average school does not spend 25% of their budget on the top 25% of their students.

Not gonna lie, I checked their price and it didn't jump 200% in one day. so...?

As the article questions - "Is this a super-specific single use case, or something that will be able to roll out to a wider market?"

Reading the other comments, and understanding that the technology (brake-to-charge) exists already in the market, I wonder what is the 'patentable' thing that would propel their stock. Would they manufacture engines & components (i.e. to install to every wagon's braking system?) Doesn't that IP/patent already exist?
A basic, white, 18-20 cu ft refrigerator/freezer can still be purchased new for under $400 in 2023 dollars. In the 1950s, a TV or refrigerator was a major purchase for most families. Therefore there was more concern over quality of materials, repairability, and longevity.

Today, a TV is basically a throwaway item. Nobody really repairs them, if you have a problem under warranty you exchange it, or if it's out of warranty you replace it. Refrigerators, laundry machines, are not far behind.

If you wanted a repairable appliance built solidly enough to last a couple of decades, you'd be paying the inflation-adjusted 1950s price. Instead you're paying much less, for something that you will probably want to replace anyway due to changing standards, changing styles, better efficency, more features, etc. (Who would still be interested in using their 19" CRT television in a heavy wood console cabinet in 2023?)
I agree but this blog post is hardly about that. It’s way less “companies bad, OSS good” as I expected it to be after reading your comment.
"MySQL is probably still the world's most popular open source database by install base."

I wonder how much of that statement is a result of (1) WordPress and (2) large web hosting providers who only offer MySQL as a database (because WordPress is the dominant hosting need)?

Good point. I got into a few discord groups about that. But I've seen some issues, everybody is very motivated.. but about incompatible things. So it doesn't work well (at least so far).

To the point I was investigating the value of money (which I often despise).. because all of a sudden, people collaborate a bit more when there's a stupid material advantage in the end.
I actually like the metaphor, although I agree it's flawed.

> "Extraction" in the literal sense of pulling something out, when dealing with physical material means that others cannot have what you've pulled out; it's gone.

For instance, look at the amount of brainpower wasted on using tech to steal our attention via adtech (and its supporting industries), large companies using OSS to increase their monopolies instead of giving back, small companies trying to build nothing of immediate value, but rather blitz-scale so they can get sold at valuations not reflecting their value.

Not sure if this was the feedback you were looking for but I spent about a year in a similar field trying to build out a product before we successfully pivoted. The product was very similar to grid.is

Ours was really tough sell as a product because it wasn't really a product. It was kind of a no code platform that worked with excel models. It was technically very capable and cool, converting excel logic to run in browser but no one really cares about the tech, but what are you supposed to do with it. And you can use it for a lot of things, like someone can embed it into an existing website to serve as a calculator (eg. Mortgage calculator), you can run Monte Carlo on workbooks easier or a solver, share simplified workbooks hiding the model guts, etc

But it wasn't a product. Every one of those problems (are they problems?) Could have been solved in a better way. No code space is also very competitive and we knew we couldn't keep up with the high bar of generalized no code platforms and the sell wasn't big enough. It was classic solution looking for a problem

Luckily we stumbled on one workbook people actually used and realized that we were held back by our old tech and built a solution to address that one problem the wb was trying to solve.

So all that's to say I think you should focus on a single very specific problem you're trying to solve (something a lot more specific than "data stories"). And think about the pricing and how many $15/mo subs you need to support your team.

I may be way off and you may already have a few thousand active users and are well on your way in case disregard what I said (we got maybe a dozen or so users at a higher price point but very little actual usage)

I have a lot of other stories to share if you're curious. But best of luck.
They're a liability of the airline, and they're an asset of the customer, but they are not an investment, because they can only go down in value, not up.

So I'm no database guru or anything, but I do spin up a database instance for projects from time to time. These days it's more likely to be SQLite rather than a multi-client one like MySQL or Postgres but it does still happen.

I choose Mysql every time, despite knowing that Postgres has been "better" historically for a few things. The reason is simple, I can get my shit done a lot faster in MySQL. I can type "SHOW TABLES" and ... see the tables, instead of looking up in the manual for whatever obscure escape sequence is required for Postgres. When I do a SELECT * in the shell, the default is a nicely formatted result that's easy for me to read. That's not my experience with Postgres.

I know that Postgres can do all these things, but I don't care - MySQL makes it easy, and that's one less thing to keep track of. Less barriers to entry == more times I'll use it.

Just my $0.02.
Yep, helped a friend buy a $700 LG yesterday. No features beyond a freezer box and fridge box. No water dispenser, ice maker, no holes through the door, nothing. Just two boxes that get differently cold. I expect it'll last 10 years+.

And without any of those features, it has the most internal space too. All that add-on crap takes up space that could be used for food.
Java Class Loader System
Honestly, I'd say most engineering is like that outside of the software world. In the classic engineering disciplines with actual licensures at the end of the pipeline, the responsibility and ethics of this are ingrained into students from day 1. (Budget and importance of the application doesn't always allow for the indulgence of this though, at least to a point.)

This type of thinking also follows from decades of experience.

For some reason the software engineering world largely abandoned esteem and respect for all of the above.
I just had a glimpse look at it. A good sum-up.

It seems that these topics are covered by the first one or two semesters of a Math degree. Of course university is a bit more advanced.
I think this is a good example of the VC mindset, but I think it is also flawed on their part.

LLMs are a lot more like a generalized processor than people are admitting right now. Granted you can talk to it, but it becomes significantly more capable when you learn how to program it -- and thats where the value will be added.
> ... just having the same x86 architecture I run on my desktop and servers.

Yep! For me, it's the same ARM64 architecture I run on my desktop and servers[1]. :-)

Hetzner's offering is very competitive, cheaper than their already rock-bottom x86 offerings. Then there's AWS Graviton, Oracle with their free tier (not sure how expensive that gets if you actually have to load it) and both Azure and Google also have ARM offerings.

And despite being a leading IoT innovator for decades, myself (I designed and manufactured the world's first embedded web-enabled wireless and PoE sensors), there is almost nothing useful in having WiFi/Net-connected appliances, especially if they require an app or cloud services of any kind. (Seriously, what kind of state do you really care about even for monitoring, much less control, in your appliances? Unless you're a wack job, pretty much zero...)
The big change of the last decade has really been the cloud explosion and with it a serious bias towards valuing deployment and operations over development, to the degree that if you're doing development which is not about deployment and operations then you're a sucker.

The emergence of the LLMs etc makes the classic open source business model of relying on incomprehensible documentation to drive people to pay you as a consultant fall apart as they will get answers on demand. You just have to look at things like Docker to see how hard it is to turn even wildly successful projects into viable companies even before all this.

> It's not 12%, it's 18% as a whole company. 12% is 20 year average.

So, 12%. Got it. One successful year doesn't paint much of a picture. Especially when you remember that employees don't usually take pay cuts when business is not doing so well. In many jurisdictions, it is even illegal to see employee pay cuts.

I was thinking about the essence of open source recently, and I came to the following conclusion: open source is when you treat people as developers, not as users. Which means: it should be trivial to build and run from source, debug, add extra logs and apply patches. Moreover, creating and applying your own patches should be encouraged, anything that can be easily patched shouldn't be a configuration option.

Most corporate "open source" fails this test, they treat people as users, create marketing websites while publishing zero developer documentation.

What's interesting, JS ecosystem accidentally has this property, thanks to packages being distributed as source, standard logging system (console.log) and widespread use of `patch-package` tool.
It would be interesting if those were two different systems: a system where the outcome is a declaration of "what the state believes to be true" being entered into the books; and then another system that — perhaps quite efficiently — can just consume the output of the former system, to evaluate the application of law in the deciding of punishments for crimes. An "is" system, and an "ought" system, per se.

There actually is a very limited "is" system in use in common law in many countries — the https://en.wikipedia.org/wiki/Inquest (usually: "coroner's inquest.") But they're really only used in practice to find cause-of-death. A "libel inquest" would be quite novel.

> To the contrary, building off the OSS ecosystem can make it healthier, if for no other reason than they are cultivating more engineers that know how to use these tools. "Extraction" is not the right metaphor.

It can, but it often does the opposite. "Extraction" may not be a metaphor that's quite true to the material. But it's very true to the attitude with which many companies operate, and that's because a lot of business culture was developed in extractive contexts and then applied elsewhere.
Yet slips are bound to happen, while systematic security measures could have prevented the accident even in the presence of slips. Though perhaps there is a difference between drama and tragedy. Or between superficial and thoughtful.
