They didn’t use goroutines, which is explains the poor perf. https://github.com/matttomasetti/Go-Gorilla_Websocket-Benchm...

Also, this paper is from Feb 2021.

http.ListenAndServe is implemented under the hood with a new goroutine per incoming connection. You don't have to explicitly use goroutines here, it's the default behaviour.

Doesn't seem to completely line up that they're rushing out iOS updates (ie for phones, etc) for something they're saying they've only confirmed on Intel cpus.

Unless they're assuming it's exploitable on Apple Silicon as well, or are being extra careful just in case.

initplus · a year ago

Will be an underlying safety issue in some system library, but they have only seen "in the wild" exploits targeting Intel. "Defence in depth" - better to push the bugfix to all than to scrutinize ARM security features to understand if an exploit is possible there as well.

I believe pricing was mid 6 figures per machine. They're also like 8U and water cooled I believe. I doubt it would be possible to deploy one outside of a fairly top tier colo facility where they have the ability to support water cooling. Also imagine learning a new CUDA but that is designed for another completely different compute model.

initplus · a year ago

Yeah you can see the cooling requirements by looking at their product images. https://cerebras.ai/wp-content/uploads/2021/04/Cerebras_Prod...

Thing is nearly all cooling. And look at the diameter on the water cooling pipes. Airflow guides on the fans are solid steel. Apparently the chip itself measures 21.5cm^2. Insane.

> Politics injecting a shit load of public money thinking that if you give the money you will be able to reproduce American company success

The problem with public funding is not the what but the to whom?

It works fine if you put the right person in charge.

However, there are very few signals to prevent the wrong person being put in charge, as it removes most considerations / incentivizes private industry uses. Which themselves are already tenuous!

initplus · a year ago

It's not just that there are few signals to prevent the wrong person being put in charge, but this kind of government bureaucratic actively selects for the wrong person. These kinds of government IT projects are often soul sucking to work on, and so they attract a specific kind of applicant.

Exactly this.

I am working on a solution to make it easier to hit the button from the front of a rack shelf, but the fact I have to mess with 3D printing just to hit a power button is silly.

Older Macs also had the power button on the back, which was also annoying, but at least a Mac that's secured to a shelf could have its power button pressed pretty easily.

The Mac mini _requires_ a mechanism to press up from the bottom in any permanent-ish install.

I mean they aren't designed for rack mounting? It's a consumer product, likely <0.1% of units produced will end up in a rack.

The GP's same argument also applies to the Magic Mouse, as it happens:

> It's a way of signaling how the product should be used.

In the Magic Mouse's case, it came out just on the cusp of wireless mice becoming "a thing." Most people, if they were allowed, would have just left the mouse tethered to a computer by its charging cable at all times, since that's what they were used to. But Apple thought you'd be happier once you stopped doing that. So someone (Ive?) decided to make it so that you couldn't charge the Magic Mouse and use it at the same time. This did two things:

1. it forced people to try using the Magic Mouse without any cable connected, so that they would notice the added freedom a wireless mouse affords. It was a "push out of the nest."

2. it made charging annoying and flow-breaking enough that people would put it off as long as possible — which would make people realize that the Magic Mouse's battery lasted for weeks on a charge, and so you really never would need to interrupt your flow to charge; you'd just maybe leave it plugged in to charge when you leave work on a Friday night (and even then, only when it occurs to you), and that'd be it.

---

One could argue that the truly strange thing, is that Apple has never changed this design, 15 years and one revision later. That's an entire human generation! Presumably people these days know that peripherals can be wireless and have long battery life.

But consider: Apple's flagship mousing peripheral — the one shown next to the Magic Keyboard in all product marketing photos — is the Magic Trackpad, not the Magic Mouse. The Magic Trackpad is the first-class option for multitouch interaction with macOS; some more-recent multitouch gestures don't even work on the Magic Mouse. (The Magic Mouse never got "3D touch", for one thing.) In other words, the Magic Mouse is basically a forgotten also-ran at this point — something just there on the wall in the Apple Store for those few people who can't stand the idea of using a desktop computer through a giant trackpad.

Which leads to an interesting question: what is the user-profile for the person who buys (or is bought) a Magic Mouse in 2024?

Well, probably one major user-profile is "your grandpa, a retiree from a publishing company, who's been using the same computer he brought home from work 20 years ago, until it broke last week — that computer being a Power Mac G5 with a Mighty Mouse; and who has never had a laptop, and so never learned to use a trackpad."

And if the Magic Mouse user is your grandpa... then said user probably does still need the cord-cutting lesson that the Magic Mouse "teaches"!

initplus · a year ago

The port on the bottom is really the least offensive element of the design. I know people find it fun to clown on, but if any of them had ever used one for 5 minutes they would realize it's a terrible mouse for a bunch of other more important reasons (weight, feet quality, tracking accuracy, polling rate etc.).

rileymat2 · a year ago

This conversation is confusing without the FDA isn’t everything allowed by default and you get far worse like the current supplement industry?

initplus · a year ago

Regulatory challenge is that the FDA have to combine 3 related but seperate concepts:

1. Manufacturing quality/ingredients accuracy (is the product what is says on the tin) 2. Safety 3. Efficacy

Medicines must pass all three, supplements don't have to meet any.

initplus commented on Apple introduces iPad mini built for Apple Intelligence apple.com/newsroom/2024/1... · Posted by u/diwank

gcanyon · a year ago

If it were possible to do so, I would possibly buy this as my new "phone":

   - I almost never hold my phone to my ear
   - I don't need the dual-lens features of the new iPhones
   - Standby battery life seems up to the challenge
   - Apple doesn't offer the iPhone Mini anymore, which is what I'm carrying now. If I'm going bigger, why not actually go BIGger.

Things holding me back:

   - Not actually sure about the battery life
   - As far as I know you can't transfer your actual phone line to a Mini

initplus · a year ago

You'll likely run into frustrating app availability issues. Releasing iPhone apps on iPad is not universally done. (looking at you WhatsApp)

If you follow news in France, it’s been shown and been shown in court cases that certain pesticides, commonly used in wine farming, cause Alzheimer’s and Parkinson’s.

They have much higher rates of these diseases, and recently in a court case the death of a farmers daughter has been shown to be caused by these pesticides.

Court isn't the place for scientific inquiry into these issues. It's just not setup for it. French courts have also found in favor of "electrosensitivity" issues.
