You know he's not actually coding the software, designing the cars, or the battery tech, or the rocket trajectories, right? He's a CEO, he's a glorified mid-level manager.

The real greatest technologists here are the engineers that have to put up with him. Maybe he should listen to them and we wouldn't have cars that actively tried to drive us into trains! https://qz.com/tesla-full-self-driving-train-1851489554
This itself is a fallacy derived from the Keynesian crowd. There isn't unlimited demand for labor and never was. In the real world at microeconomic and local levels, labor demand is absolutely limited to discrete job posting and people who are already employed. This number is ultimately countable and finite. There are not infinite jobs available.
Conversely, I bet that Musk has so many demands on his time that he doesn't go to any meeting that isn't 100% essential.
You had me thinking we were in some type of simulation for a second.

B+ Trees (which store data at leaves) rather than B-Trees are what you want for good iteration performance usually.

An ordered B-Tree iteration would jump between different arrays in the tree often, but a B+ Tree would only have you jump to another array once you’re done iterating over all the elements in the current array.

Congratulation on upcoming new addition to your family!
> 35) When you dig deeper there's a range of other peculiarities at Tesla. Unlike every other S&P/OEM company, Tesla uses its own ERP system (vs Microsoft, SAP, Oracle etc) called WARP - which when you consider the accounting / governance issues is worrying erpresearch.com/knowledge/whic…

Out of all the things you could pick on, this actually makes Tesla look good.

The "standard" ERP systems are steaming dogshit. They are terrible. They make everybody miserable. And they don't do a damn thing to prevent accounting fraud.

Every company I have worked for who had their own ERP system thought it was terrible ... and then SAP/Oracle came in and everybody realized that things somehow got so much worse.
I think gcloud has CAS by comparing etags. Surprised to hear S3 can’t.
You can have a rational discussion about a company without it being an attack on the CEO.

In absolute numbers, Tesla is underperforming relative to previously. It is worth examining why and understanding if this is a blip or an accelerating trend.
> Good abstraction layer: length prefix, or JSON encoding.

> Bad abstraction layer: (...)

In this context, it shouldn't matter. Sure, "mostly plaintext except some characters in some special positions..." is considered bad in modern engineering practice, however it's not fundamentally different or more difficult that printf and family. You wouldn't start calling printf without at least skimming the docs for the format string language, would you?

> It is a bad engineering decision, and it also obfuscates the fact that there even is an abstraction layer unless you carefully read the spec.

There's the rub: you should have read the spec. You should always read the spec, at least if you're doing something serious like production-grade software. With a binary or JSON-based protocol, you wouldn't look at few messages and assume you understand the encoding. I suppose we can blame SMTP for design that didn't account for human nature: it looks simple enough to fool people into thinking they don't need to read the manual.

> There are very few good reasons to use a text-based data interchange format.

If you mean text without obvious and well-defined structure, then I completely agree.

> One of them is to make the format self-documenting, such that people can easily read and write it without consulting the spec.

"Self-documenting" is IMHO a fundamentally flawed idea, and expecting people to read and write code/markup without consulting the spec is a fool's errand.

> it should be binary - then you have to either read the spec or use someone else's implementation.

That's mitigating (and promoting) bad engineering practice with protocol design; see above. I'm not a fan of this, nor the more general attitude of making tools "intuitive". I'd rather promote the practice of reading the goddamn manual.

> But there's no excuse for the brain-dead approach that SMTP took. They didn't even use length prefixing,

The protocol predates both JSON and XML by several decades. It was created in times when C was roaming the world; length prefixing got unpopular then, and only recently seems to en vogue.
There is not a batteries included framework a-la Django or Rails for Clojure. I would argue that is one of the biggest pitfalls to the language/ecosystem. If you are building a web application, you will need to invent the entire thing yourself. There are micro frameworks and tools that exist standalone to deal with HTTP, DB ORM, etc... but that will be an exercise left to the reader.

Some will say this is a good thing (and as a very experienced engineer I will agree) but the barrier to entry for a newbie is quite high in this regard. You have all the rope to hang yourself with - and you will. Especially if you are on a team full of lots of interns and junior folks.
as long as supply << demand.
Ah, I missed the "copy wholesale" aspect.

When I started reading it, the first thing that came to my mind was the issue with copying the structs. The article started looking at the issue, but didn't really follow further with the changes needed to make it work, which is that you start needing to introduce tracking which instance is responsible for the resources and providing a way to transfer that responsibility (a.k.a. ownership and move semantics).

Cross checking with units : A coin of diameter 25.4mm=0.0254m has an area of pi(0.0254m/2)^2=0.00016129m^2, and 9.81N/kg450kg/4=1103N, so that gives 1103N/(0.00016m^2)=6.819MPa. Sounds right, pascals are quite small. :)
Right. It's the workers that have zero value add and not the people who sit in offices or at home making hundreds of thousands, tens of millions, or hundreds if millions doing a job anyone could do or even a job that isn't needed at all.
Yup. I often find people learning ML Engineering struggle a lot with shapes and broadcasting. The goal of these puzzles is to force you to really learn the semantics of broadcasting and internalize that data shapes in ML correspond to how most people think about loops.

S3 Object Lambda solves a lot of these "problems" with this design
This matches my experience as an amateur programmer. The initial hill was steep, but I don't think it was because people weren't friendly.

There is one cultural thing that might be confused with unfriendliness. Sometimes people react badly if someone posts incorrect information. But I think that's good. When you search for information about Python or PHP you have to wade through quite a bit of junk. Ironically, it's sometimes easier to find correct answers for Clojure.

Clojure itself is very clean and consistent, it's got a lot of polish to it, which makes it comparatively easy to learn. And there isn't that much of it. But for a long time the tooling was hard.

That's far less of a problem than it used to be. deps.edn and shadow-cljs both made things easier, as has Cursive. People say nice things about Calva, but I don't know it.

I'm a big fan. Babashka alone is enough to make learning Clojure worthwhile. Also, for someone like me, it's kind of nice that it feels almost finished. Once you learn it, you know it, and now that the tooling has settled down a bit you don't have to keep running to keep up.

The suggested code tests for bitfield borrows with

Couldn't this be written equivalently as

auto c = x ^ y ^ (x - y);
c &= 0x10820;

where the literal bitmap now contains the bits just left of each bitfield?

Many people around the world can invest only small amounts per month. A 1000$ price makes the entry high.

The underlying logic is that lower per share price would increase volume and maybe a bit the price.

This seems like it's unrelated to divorce.

I don't think it's fair to look at divorces on a century basis given that no fault divorce only became possible in the United States in 1969 - before that you needed to prove there was some sort of abuse or infidelity involved.

It certainly becomes more complicated to try and draw trends, and impossible to assume it was stronger family value that held them together before that point - in fact, the peak in the early 70s indicates that once it became possible it was used with gusto.
This stock is a great example of invest in stocks where you have strong knowledge.

I invested last year at ~$250 when redditors we're posting that "Nvidia is the best shorting opportunity" without any of the knowledge of the market.

It looks like it's now going above $1000 and still going up.

I cannot trust any company with any modicum of success not to immediately exit into the hands of megacorps. I cannot hope that companies have any type of morality/"want to make the world better" anymore.
All that means is the market already expected the result to be a good one. The share price already went up on that expectation.

Snowflake Announces Agreement to Acquire TruEra
We all understand that this cannot and will not continue, right? One of two things happens:

1. The AI boom goes bust. Nvidia sales and/or margins crater. The stock craters with it.

2. The AI boom is the real deal. Companies aren’t stupid and won’t keep paying Nvidia these prices forever. Pretty soon hardware and software architectures are standardized enough that anyone who can get onboard with TSMC, Samsung, or Intel can churn out hardware optimized for the right few functions and sell for a faction of the price. Nvidia can still be an innovator but they won’t be able to sell “bread and butter” products at these prices. Sales and/or margins crater, as does the stock.

Ethics among programmers is for sale, sadly.
During an internship, I was part of a team that developed a collection of tools [0] intended to provide pseudonymization of production database for testing and development purposes.
These tools were developed while used in parallel with clients that had a large number of database.

Referential constraint refer to ensuring some coherence / basic logic in the output data (ie. the anonymized street name must exist in the anonymized city).
This was the most time consuming phase of the pseudonymization process. They were working on introducing pseudonymization with cross-referential constraint which is a mess as constraint were often strongly intertwined. Also, a lot of the time client had no proper idea of what the field were and what they were truly containing (what format of phone number, we did find a lot of unusual things).

(I don't necessarily no-sell all that boosterism, either. The most basal ancestor of today's GNU Emacs dates to the mid-1970s; if the 'Lindy effect' holds true, it really is the 100-year editor.)

You ought to have the system detect slow progress / low success during the first 5 minutes, and then go "wait, this isn't working, try Plan B with much smaller chunks", and switch to drilling on a smaller number of questions over and over until the recall rate is high. Slogging through a long sequence of fail,fail,fail,fail does not generate enthusiasm or a sense of progress.

From your description, it sounds like, when a user flubs a question in a session and is shown the answer, you do not quickly re-test them on the same question during the session to improve recall, but just go on to other questions instead.
At scale?

transparent HA means that I can fail over services to other regions without having to get the programmers to think about it. Most of the busy work at scale is managing state or, more correctly recovering state from broken machines.

If I can make something else do that reliably, rather than engineer it myself, thats a win.

So much of the work of standing up a cluster (be it k8s or something else) is getting to the point where you can arbitrarily kill a datastore and it self heal.

If you're talking about s3 partial updates, its about cost/and or performance. If you dealing with megabyte chunks, and you want to flip a few bytes over hundreds of thousands, thats going to eat into transfer costs.

Sure you could chunk up the files even smaller, but then you hit into access latency (s3 aint that fast. )
The paradigm can be flipped now for these distributed storage systems.

The blocks of a filesystem can now be objects, replicated or erasure-coded - like Ceph running filesystems on top of its low-level object storage protocol, which is done on raw disks, not a filesystem.

This can't be done for something like Minio just running on your filesystem, but if you're building the storage system from the ground up it can.

We will see more and more of these products appearing.

Those use strontium-90, which decays much faster than americium-241. That makes it hotter, at first, but its useful life is less. Being more than 4x less dense, you might carry enough more to make up the difference (and discard the extra heat, at first) if you have the room.

Strontium-90 decays by beta emission, ending up as stable zirconium, meaning you don't have to vent helium.
