Literally every industry publication and BOM analysis since... the first iPhone?
genmud··on TSMC Arizona chip plant will be a paperweight
That's what they keep saying, but other projects seem to be able to get stuff built just fine if they are paying market rates.

From what I hear, they are being extremely tight with their budget, while simultaneously demanding aggressive timelines. These things are for the most part, mutually exclusive.

genmud··on TSMC Arizona chip plant will be a paperweight
They aren't asking to bring their PHDs or material science people... my understanding is they are asking to bring project managers, foremen, construction workers, pipe fitters and electricians.

I live about 10 minutes away from the plant and anecdotally from what I can see of the Taiwanese employees, most seem to be people who are in jeans and cotton work shirts... not button downs or polos.

genmud··on Foxconn's promise to invest $10B in Wisconsin is now a distant memory
No, because in the case of TSMC, they actually are building things in AZ and have already spent hundreds of millions on construction.
genmud··on America is building chip factories. Now to find the workers
There needs to be more money and/or a non 4 year degree path for more of these jobs if they want to fill them.
genmud··on Lidar on a Chip Puts Self-Driving Cars in the Fast Lane
This is really neat, there are some really cool, low cost integrated packages for ToF sensors (not what the article was talking about though). ST makes a bunch of them and they are surprisingly small.
genmud··on Linus Tech Tips: What do we do now? [video]
While I'm one to frequently laugh and dismiss "nerd drama", GN has some pretty valid points, considering how much reach and influence they have on the PC market, candidly dismissing it as "online drama" seems a bit hand wavy.

The follow up from GN [1] was interesting as well... ironically many of the techniques Linus used in his response are taught in PR and crisis communications, telling me that they didn't really care or understand the scope of the issue.

genmud··on Ask HN: How do you look for jobs in 2023?
Walmart has like 2 million+ employees, which is insane to think about. I have worked at a few ultra huge corps, one which had about 140k people, and like 240k devices in their org.

When I changed jobs there in 2007, I had just come from a hosting provider where we had engineers that managed 500-1000 servers per person, depending on their role or the amount of automation. It was like I stepped back in time to 1999 and everything was manually managed/maintained.

genmud··on New York Times: The U.S. government should end its prosecution of Julian Assange
I think it would be fair to stop prosecuting him if he stopped being an active adversary of the US.

I’m a firm supporter of holding the US government accountable when they do bad things, however, Assange is most definitely not someone who is partial or somehow morally correct in his behavior.

During his years of activity, he has been a willing conduit for a number of foreign intelligence services and has actively put his thumb on the scales to harm US interests. His closeness and willingness to launder FSB, GRU and MSS data stolen from western governments make him a legitimate target for the US government.

He isn’t a hero like some people want to believe. Fuck that guy.

You don't even want to know how little security is in the RF signals garage door openers use.

Most use rolling codes, but those have a fairly small key space, which is further reduced by manufacturer IDs.

genmud··on Arizona restricts Phoenix home construction amid water shortage
Arizona resident here...

We have a canal that goes to the Colorado river, and Phoenix is in an active management area (AMA) water district. The state is actively working to be at a point where the canal isn't necessary to supply our water needs, and any excess capacity gets "banked" into aquifers or water reservoirs. People love to shit all over Phoenix for being in the middle of a desert with no rivers, but there are some extremely well managed and healthy aquifers out here (and ones where it's the Wild West, which is what you hear about on the news, like in Rio Verde).

In fact, the water management here is probably one of the most forward thinking and strategic in the entire country.

Our aquifers in Phoenix have been RISING since we enacted more stringent measures in the 1980s. Read that again, because it surprises people, but we have more water in most of the Phoenix metro water wells than we did 40 years ago.

Last I heard, we were planning on being entirely water neutral for our water aquifers in Phoenix, Prescott and Tucson by 2025. That means like 80-90% of the states population will be located near water sources that are sustainable and well managed.

genmud··on How real is America’s chipmaking renaissance?
Do you not keep track of current events?

Chinas activities in the South China Sea, the fact they openly say they will integrate Taiwan, by force if necessary and unemployment being 20-30% for young people are just a few red flags.

genmud··on USB-C Confirmed for the iPhone 15
I have had experience where the cables/connectors are just a hair bigger than spec to provide a better connection to the shield, and they cause the receptacles to wear and become loose over time. Then you use an in spec cable and it's loose.
genmud··on JTAG 'Hacking' the Original Xbox in 2023
Decapping is well within the realm of hobbyists, I have thought about putting together an open source equivalent of the JetEtch, which can sometimes be found on eBay for fairly cheap. My main concern is that the chemicals used are really dangerous.

Things like laser glitching are feasible in the $thousands range and power or RF glitching is in the $hundreds range.

With low cost fiber laser cutters and etchers, lots of techniques can be applied. I imagine with the high resolution X-ray stuff starting to come onto the used market, lots of things for hardware hacking will become extremely affordable.

genmud··on Nuked-MD-FPGA – Emulating Sega Mega Drive chipset using decapped chips photos
I don’t think the old gaming hardware really ran an OS in the way you think of it.

IIRC the cartridges were effectively just PROMs (I could be wrong and maybe they were fabbed / silicon and didn’t get programmed) which held the application code.

genmud··on FCC allows blocking traffic from robocall-friendly provider One Owl
If a bank is comprised of 66% of their customers being narcos, the bank gets shut down.

You don’t get to facilitate in illegal shit and hide behind your legitimate customers. Likewise, if you are a customer of theirs and know they heavily transact with illegal services, it’s on you for getting blocked.

Yes
genmud··on TPG, Francisco to take software firm New Relic private in $6.5B deal
It feels like CA is one of the most litigious companies in software, maybe worse than oracle for patent shenanigans.

Just because they settled, doesn't mean the whole story is being told. There is nothing any of these companies have been doing that are massively novel.

Call the abuse department, not sure if they still are like they used to be, but they used to be 24/7 and would actually pick up the phone, 480-624-2505.
genmud··on Systemd 254 released, deprecating sysvinit scripts
Oh goodie, another way for shit to break and force maintainers to write systemd only service scripts.
genmud··on Cigna Sued over Algorithm Used to Deny Coverage to Thousands of Patients
I would rather write software for precision guided bombs than write software for a U.S. insurance company. Over the course of your career, the bombs will by far have been responsible for less death and ruin fewer peoples lives.
genmud··on Ask HN: What is the best thing you learnt or got out of Hacker News?
I think the constant drip of interesting hardware related stuff has gotten me out of my software comfort zone.
genmud··on Intro to Drone Detection Radar with Emphasis on Automatic Target Recognition
It certainly was an intro, but not very comprehensive, and feels like it was written by people who obviously don't have much first hand experience with counter UAS or counter battery offerings.

The things they were talking about with regards to target ID and recognition have existed for many, many years now. Most counter battery radars that I am familiar with could be fitted with electro-optical systems for ID, and that was at least 10-15 years ago.

genmud··on Intro to Drone Detection Radar with Emphasis on Automatic Target Recognition
I would say the majority of them that I have seen online are very obviously using jammable transmissions.

It shows how having distributed EW capabilities are really important if you wanna keep your vehicles alive.

genmud··on Hollywood is on strike because CEOs fell for Silicon Valley’s magical thinking
> I'm not clear on how long residuals can last in a sustainable way

They were possible before, since there was much less content available at any given time. The media industry is in a bit of a death spiral it feels like, with a race to the bottom in many ways.

When broadcast tv was a bigger thing, syndicated shows were licensed to stations, who typically sold ad slots, allowing them to pay the licensing fees.

The problem is in many ways streaming platforms just really aren’t that cheap to run in the US when compared to old methods of distribution and the margin is almost entirely going to the platform, not the people making the content.

genmud··on Big Tech as the New Big Tobacco
But all of these businesses have dirty, neutral and clean heavily commingled.

Meta is an ad company and has a device business and happen to use social media to sell ads.

Amazon is rapidly shifting to be an ad company, who happens to use an e-commerce platform to place ads. They bought a healthcare company who collects massive amounts of PII and provide affiliate programs which funnel traffic into their ads and marketplace.

Apple, Microsoft and Google all have ad units that are major contributors to their overall profitability.

genmud··on Ask HN: How to find users (developers, DevOps) for paid market research?
Depends on what your budget is. Posts on HN for the area of focus, specifically on threads can be great ways to find people, though might not be the easiest way to do it. Most of the time I just ask former coworkers or ping mailing lists.

I'll give you feedback on your process or product if you want.

genmud··on An invitation to a secret society
Yea, it totally should be. Many of the ultrasonic sensors from robots use similar methods, but all this stuff could be wired up to simple projects.

I would be interested in exploring with you if you wanted to.

genmud··on An invitation to a secret society
Are you in Arizona? Any tips on where to start?
genmud··on An invitation to a secret society
While I totally get where you are coming from, I don’t think integration is necessary in 99% of usage. Sure, it helps people build intuition in the field they are specializing in, and for those people it can be invaluable, but having a better way to recall things would solve most use cases.

IMHO the biggest disservice to students in much of the education system in the US (including some colleges and universities ) is the focus on memorization vs focusing on problem solving. The older I get, the more I reflect on how much opportunity was wasted with poor quality teachers who just wanted us to memorize facts and be able to reproduce those facts in tests.

I don’t need to memorize maxwells equations to know that they exist, what they focus on, or how they can be applied to certain problem sets.
