Hi! Great post, good research with sources, great initiative, thank you. 🙏

Glad to learn that HTTP/0.9 is still “in use globally” then. A bit surprising, but since it’s all about stretching definitions past what is reasonable, for the sole purpose of having the last word, let’s shoehorn anything into anything to the infinity and beyond!!! 🤡🚀

It turns out that “Women Who Code Closing - Women Who Code” actually isn’t about Women that code a software called “Closing”, and Women that code in general.

In fact, what they meant to write was:

The End of an Era: “Women Who Code” Closing – Women Who Code.

I know I’m gonna get downvoted for this, but punctuation matters, and sadly, it has to be said. So here I go.

Maybe they mean it in the sense of “forgery”. You know, as in “let people imagine what it is like to have friendships, by letting them make forgeries of their lives, but with friends in it” 🤪

Fuck yea!

I think we can all agree on that… But without the entire article, one can only parametrise their answer… I was hoping someone with a full version could do an HTML dump. 😅

Or at the very least a markdown dump in here.

Is it using XLR?

Is it just me, or is everyone here commenting on a half article, the other half being behind a paywall? 😬

I think you’re overstating the compute power […]

I don’t actually think so. A100 GPUs in server chassis have a 400 or 500W TDP depending on the configuration, and even if I’m assuming 400, with 4 per watercooled 1U chassis, a 47U rack with those would consume about 100kW with power supply efficiency and whatnot.

Running those for a day only would be 2.4GWh.

Now, I’m not assuming Amazon would own 100s of those racks at every DC, but they probably would use at least a couple of such racks to train their model (time is money, right?). And training them for a week with just two of those would be 35GWh, and I can only extrapolate from there.

So I don’t think that going to TWh is such an overstatement.

[…] and understating the amount of cardboard Amazon uses

That, very possibly.

I have seldom used Amazon ever, maybe 5 times tops, and I can only remember two times. Those two times, I ordered a smartphone and a bunch of electronics supplies, and I don’t remember the packaging being excessive. But I know from plenty of memes that they regularly overdo it. That, coupled with the insane amount of shit people order online… And yes, I believe you are right on that one.

Even so, as long as it is cardboard, or paper, and not plastic and glue, it isn’t a big ecological issue.

However, that makes no difference to Amazon financially, cost is cost, and they only care about that.

But let’s not pretend they are doing a good thing then. It is a cost effective measure for them, that ends up worsening the situation for everyone else, because the tradeoff is good economically, and terrible ecologically.

If they wanted to do a good thing, they could use machine learning to optimise the combining of deliveries in the same area, to save on petrol, and by extension, pollution from their vehicles, but that would actually worsen the customer experience, and end up costing them more than it would save them, so that’s never gonna happen.

IMHO the issue is two folds:

1. The makefile were never supposed to do more than determine which build tools to call (and how) for a given target. Meaning that in very many cases, makefile are abused to do way too much. I’d argue that you should try to keep your make targets only one line long. Anything bigger and you’re likely doing it wrong (and ought to move it in a shell script, that gets called from the makefile).
2. It is really challenging to write portable makefiles. There’s BSD make and GNU make, and then there are different tools on different systems. Different dependencies. Different libs. Etc. Not easy.

Yeah, it is one of the least bad uses for it.

But then again, using literal tera-watts-hours of compute power to save on the easiest actually recyclable material known to man (cardboard), maybe that’s just me, maybe I’m too jaded, but it sounds like a pretty bad overall outcome.

It isn’t a bad deal for Amazon, tho, who is likely to save on costs, that way, since energy is still orders of magnitude cheaper than it should be^[1], and cardboard is getting pricier.

The thing is, devops is pretty complex and pretty diverse. You’ve got at least 6 different solutions among the popular ones.

Last time I checked only the list of available provisioning software, I counted 22.

Sure, some like cdist are pretty niche, but still, when you apply for a company, even tho it is going to either be AWS (mostly), azure, GCE, oracle, or some run of the mill VPS provider with extended cloud features (simili S3 based on minio, “cloud LAN”, etc), and you are likely going to use terraform for host provisioning, the most relevant information to check is which software they use. Packer? Or dynamic provisioning like Chef? Puppet? Ansible? Salt? Or one of the “lesser ones”?

And thing is, even among successive versions, among compatible stacks, the DSL evolved, and the way things are supposed to be done changed. For example, before hiera, puppet was an entirely different beast.

And that’s not even throwing docker or (or rkt, appc) in the mix. Then you have k8s, podman, helm, etc.

The entire ecosystem has considerable overlap too.

So, on one hand, you have pretty clean and useable code snippets on stackoverflow, github gist, etc. So much so that tools like that emerged… And then, the very second LLMs were able to produce any moderately usable output, they were trained on that data.

And on the other hand, you have devops. An ecosystem with no clear boundaries, no clear organisation, not much maturity yet (in spite of the industry being more than a decade old), and so organic that keeping up with developments is a full time job on its own. There’s no chance in hell LLMs can be properly trained on that dataset before it cools down. Not a chance. Never gonna happen.

Do bullets kill soldiers?

Infantry soldiers in the open, possibly. Soldiers in an APC? No.

Same applies to companies. A single sufficient bad review on a small, one-person company can take it out entirely. A single review of a big corporation? Not even one from a big shot like MKBHD.

This headline is dumb.

I believe you’re missing the actual causality chain here.

While it is actually proven that vendors will degrade your experience artificially to “motivate” you to buy new devices, in the never ending pursuit of monetary gain, there is no such potential incentive here: you aren’t paying for new drivers.

And while others suggest biases, I do believe you are witnessing an effect that is at least partially real, if not totally, but not for the reasons you believe:

Most programs that leverage GPUs end up being GPU bottlenecked. Meaning that one can almost always improve the program’s performance by using a better GPU.

But then, why does a new driver not improve performance, and rather, simply “bring a degraded performance back to previous levels”?

Well, that has to do with auto-updates, and the way drivers are distributed.

While, in a world where one would have to manually update everything, a new driver would almost certainly mean better performance for a given program, most programs in our world auto-update automatically (and sometimes even, silently). And the developers are usually on top of things wrt drivers, because they follow drivers updates closely, get early versions, etc.

Meaning that when a driver is updated, your apps usually are, too. In a way that leverage the new driver for more processing, rather than faster processing. But unlike your automatically updated apps, your drivers are updated manually.

And the consequence of such updates, when you are too slow to update your drivers, is a degraded experience.

Not because anyone artificially throttled your device’s performance, but because you lag too much behind expected updates.

Seeing that I’m a senior dev, take it any way you want.

Junior dev:

Straight out of uni, know the latest developments while having also studied long established standards and specifications (like POSIX, LSB, SQL, etc), full of energy, and ready to speedrun burning out any %

Senior dev:

Hasn’t learned anything substantial in decades, uses outdated specs because “who got the time for that, and legacy stuff works just as well anyway”, copy pastes most of their work from stack overflow, is only still employed because of their inside information knowledge and the utter absence of documentation leading to a bus factor of one, and has perfected the art of gaming the system to the point of photoshopping a sloppy IDE screen over their WoW game whenever a picture of them “working” gets taken.

Yeah, checks out.

Oh. Yes, that makes sense. I read it too literally I suppose (“better to test” as in “better to give it a try”, while “better to try it first” was meant). 🤪 thank you! 🙏

Thank you very much for this post. I’m glad someone did the effort of getting some of those and presenting them from the PoV of a first time experience. I was curious.

However, I’m not sure what you meant with:

BUT when I shared it with others, people in body reported less effectiveness due to thickness of skin and under-dermal stuff, so it’s better to test it if you aren’t skinny as a skeleton.

At first it sounds like you say that overweight people have trouble using them (which is logical, the device needs to touch the bones), but then you go on saying that it doesn’t work for underweight people? I’m confused. Could you please elaborate a little? Thanks 🙂
