jocaal··on Apple is America's semiconductor problem
> But I find an article that doesn't even address any other companies a little hard to swallow. Are other companies simply not able to "reshore" chip fabs?

I urge you to look at the earnings of some of the most popular chip manufacturers and then look at the earnings of apple (also ignore nvidia as it is an obvious outlier). Creating a modern chip fab takes A LOT of money and is simply impossible when some of the most popular semi companies struggle to even make a small profit. TSMC's fabless business model allows many chip companies to share the capital investment required, but apple just straight up has the money to make the investments but choose not too. Also it would be quite scary if apple is allowed that type of vertical integration.

jocaal··on Defense of Lisp macros: The automotive field as a case in point
What they didn't tell you is that these state-machines are differential equations as well. Again, the math is more important than the code. If you want to look more into it, just search for state variable control.

> It turns out non-programmers actually like graphical tools. Go figure.

I'd rather say that visual tools are better abstractions than what text based tools can provide for those specific scenarios. Some problems are easier solved with diagrams.

The people using matlab are typically experts in things other than programming. Matlab is for people designing antennas or control systems, where the math is more important than the code.
jocaal··on Apple introduces M4 chip
> better for edge AI than whatever is out there, so I'm looking forward to this

What exactly are you expecting? The current hype for AI is large language models. The word 'large' has a certain meaning in that context. Much larger that can fit on your phone. Everyone is going crazy about edge AI, what am I missing?

Memory bandwidth is literally the main bottleneck when it comes to the types of applications gpus are used for, so everyone is counting

jocaal··on Keeping your data from Apple is harder than expected
Information doesn't have to be explicitly linked to a person in order to identify them. Search browser fingerprinting as an example. The best policy is really to not collect this information.

> I'm sorry, but I want to maximize my (and really all humans) time on this Earth, if that costs energy, that's the cost

But by using too much energy, you are reducing the expected lifespan of future generations. I can't tell if your being sarcastic. Tragedy of the commons.

In my experience, whenever relationships get involved in business, things go sideways fast. You should definitely fight this, as other people have mentioned, get a lawyer.
jocaal··on EU Probes Apple's Decision to Shut Down Epic's Developer Account
> Given one of the things you can get on an app store is a replacement keyboard, "security" is, in addition to all the things you listed, "make sure there are no installable key-loggers".

"This keyboard app requires access to network resources, do you want to allow this?" Or better yet, let the operating system block apps from using both network resources and keyboard api's.

> And for web browsers, which are basically an inner-OS, making sure that plug-ins can't read arbitrary content from the pages you visit.

My web browser allows me to choose when I want an extension to have access to a web page.

> "And given that "phone" is an app, that it can't wiretap all your calls."

I'm gonna guess it does this with a man-in-the-middle attack. "The operating system has detected that this phone app always calls the same number. We have disabled it for security reasons." Also if you buy a phone, it might be reasonable to let there only be one phone app.

I'm kind of tired of people claiming the hand-holding argument, that apple helps people who do not understand technology. My sister uses apple devices exclusively, but at her work, her employer regularly does tests for phishing and she always fails. It is time people get educated about how to use their computing devices. These devices have been around long enough that people who fall for obvious scams should be considered incompetent.

Through security enhancing features in the operating system, like not allowing processes to access other's memory spaces. Or prompting users to allow an application to use potentially harmful api's. What do you think is the role of an operating system?
jocaal··on The Psychopolitics of Trauma
Making the assumption that the majority will always make the right choice is absurd. The real value in democracy is kicking out whoever is currently in charge every few years and you can indeed do that by picking the next person at random.
jocaal··on Embedded Swift on the Raspberry Pi Pico
probably, I didn't really check it, but I found [1]. Rust has a lot of support for embedded systems, even from the companies that provide the chips, like Espressif.

jocaal··on Embedded Swift on the Raspberry Pi Pico
It scares me how many people don't realize this. A language is only as good as the things it allows you to build. Swift can be a great language from a PLT perspective, but it is pretty much only good at making apple UI's. Anything else and you are making some important compromises you might not be aware of.
jocaal··on Facing reality about the EU is a core requirement for good management
> And also to have the US stay in control, that was the deal post WW2. This is changing though, looking at how much EU countries spend in terms of GDP they are slowly closing in on the US

a quick search said the EU spent 240B euro on defense in 2022, that number is likely higher now. That isn't a small amount. If you bundled the EU as a country, that would be 3rd on the list, and puts their military spending in the same class as china. The EU isn't piggy backing off the US for defense, the US is just spending an obscene amount on defense, because how else do you make the shareholders of the military industrial complex obscenely rich?

jocaal··on Insecure Features in PDFs (2021)
Trying to design a perfect system is a pipe dream. There will always be interactions between components that weren't expected. The best we can do is fix the problems as they come and occasionally break some api's to build better systems with hindsight, but backward compatibility is such an essential requirement to customers.

Sometimes you need safety from the vendors. Linux is the only OS that doesn't use dark patterns to make me create a cloud account.

> Android tablet but I'm still yet to find one with a decent pen and memory

I don't have one, so take with grain of salt, but I've seen reviews of the Galaxy Tab s9 Ultra are pretty good [0]. Super expensive though. Also as a bonus, android is possibly getting a VM [1], so in the future you might be able to install full fat linux on high quality tablets.

jocaal··on Tesla is the worst-performing stock in the S&P 500 this year
Musk is a great CEO because he is free marketing. Tesla would be a fraction of its size without musk, not because of technical merits, but because the general public loves (or atleast loved) his wacky personality and his links with high tech. The "elon musk is a real-life iron man" statement was a thing before tesla's rise during covid. Personally I think he got trapped with self-bullshit and that allowed cracks to peel through. Had he been less open about politics and stuck with generic memes, tesla would have still been on the rise.

You can easily access the chinese version of tiktok and from what I've seen, douyin has exactly the same garbage as tiktok. These apps aren't hostile for national security reasons. They are hostile for monetary reasons.
jocaal··on Ask HN: What means to live without a phone?
When my current phone dies I won't be buying a new one. I will be buying an LTE smartwatch. That way I get to keep a number and will still be able to contact family and friends.

> How do you manage your digital life

The hope is that without a phone I won't be distracted by all the garbage that we call our digital lives. I already uninstalled all social media from my phone, including youtube. Sometimes I still get the urge to watch videos in my browser and obviously still lurke on HN.

> relationship with the Government

This stuff I do on the computer anyways.

Hopefully the experiment will work and allow me to be more open in life in person. It is so weird seeing everyone on public transport glued to their phones.

> Ok, so when is the US going to become part of the west?

I'm from Africa. Here "the west" is an expression refering to europe and the US and/or advanced democratic countries. I thought it was a common expression, I apologize if I was unclear.

> The previous elected president of the United States believes that because he's privileged - by virtue of being a nepobaby...

Trump doesn't act the way he does "because he is priveledged by virtue of being a nepobaby". He acts that way, because he is old and grew up in times where acting that way was socially accepted. In modern times it is not accepted and people are growing up knowing it is wrong.

The point of my post was basically that preaching to a tech focussed website full of mostly middle aged men is the wrong strategy. If you want to make a difference, go to the youth and don't expect change to happen overnight.

jocaal··on Orange Site Hit
> Our industry is still full of sexism and racism.

Im curious what people like you want. If you look at the rest of the world, the west seems like it is decades ahead with this sort of stuff than anyone else in the world. And social change on national scales don't happen overnight. Yes improvements can be made, but HN is a site focussed on technology and that is what is mostly discussed. If some sexism or racism or whatever slips through, thats just the world we live in today. If you look at the youth today, they are already much more accommodating towards diverse views. Just give the world time and you'll see on average things will get better. But forcing your views onto people who grew up differently than you is just annoying.

[edit] when saying "people like you" I am refering to the highly vocal inflexible people on the interwebs.

jocaal··on US ban on some Apple Watch sales now in effect
> ...giving nothing in return

Patent law is there, because creating original work is costly and can take years in engineering and scientific fields. The patents are there to give a time-window for the people who made the investments to make their money back and get some return on their investment.

jocaal··on US ban on some Apple Watch sales now in effect
Masimo made investments into R&D. They payed salaries to researchers to create new products and got awarded a patent for that investment. If the employees knew they were onto something big, they should've started a company or negotiated higher salaries before the patent was filed. If you want the reward, you have to take the risk.

Apple sits on heaps of cash and could have done the same.
