stagger87··on Claude Opus 5.5

No need to assume, the phrase is literally a link to the blog post the defines it!

stagger87··on An Interesting Fourier Transform – 1/f Noise (2007)
If you change your Fourier transform approach into a time domain convolution, then you can generate it sample by sample. White noise -> FIR filter, this is a pretty simple and direct algorithm as far as DSP goes. The wiki on pink noise mentions this. I've done the FIR filter approach to simulate 1/f phase noise.
stagger87··on QuadRF can spot drones and see WiFi through my wall
Nice project, congrats!

Rx/TX isolation?

Typical image rejection (dB)?

Does it support hardware level timestamping to align tx and rx samples through soapy?

stagger87··on Previewing GPT‑5.6 Sol: a next-generation model
> I even referenced multiple code bases on GitHub

Well, GPT referenced every GitHub code base, no wonder it won! :)

stagger87··on Ford AI hiccups push carmaker to rehire ‘gray beard’ inspectors
> The return of the veteran engineers at Ford cuts against the prevailing wisdom — and fear — that AI will replace all kinds of knowledge workers. But Ford found the machines couldn’t replace experience.

I'm not sure this story is illustrative of that, when you have a VP of engineering saying “Over prior years, we didn’t pay as much attention as we should have to the experience of our most knowledgeable engineers that have been with us through many product cycles.”

He's saving face while almost certainly trying to figure out how to make the new systems work so that next time he won't need to rehire engineers.

stagger87··on For thirty years I programmed with Phish on, every day
I'm in the same boat, I code mostly by hand. I really enjoy it. The OP seems to have given it up without a fight, and that doesn't make sense to me. Especially because with 30 years experience I'm guessing they have FU money and are probably better than most people using AI anyways. Keep doing what you love and "surrender to the flow".
stagger87··on How Passive Radar Works
Uninformed FUD, not a single dsp "trick" related to passive radar is ITAR controlled. The equivalence the OP mentioned is literally described in every undergraduate dsp textbook.
stagger87··on How Passive Radar Works
That's very evil to recommend a graduate electrodynamics book to learn more about passive radar. I would suggest taking a look at Platos Republic to get some intuition on why that is. </s>
stagger87··on Is legal the same as legitimate: AI reimplementation and the erosion of copyleft
I'm probably spitting in the wind, but stuff like this is why I removed all my hosted open source projects. I manage several niche projects that I have now converted to binary only releases (to almost no push back). It's niche enough that it's not very hard to get LLMs to output chunks of code that it managed to scrape before I took it offline. I don't see many people talking about this angle, but LLMs ripping off my work killed my open source efforts.

stagger87··on Microsoft forced me to switch to Linux
Why did you want to install windows 11 anyways? I also have a PC stuck on Windows 10 and it makes me happy that it's now stable and not part of the forced rolling releases in Win11. Im going to run it on Win10 as long as I can.
stagger87··on Open source USB to GPIB converter (for Test and Measurement instruments)
FWIW, You can buy legit used 82357s for quite a bit less than 1k. Anecdotally, I've never had one fail in 20 years. Probably bought a dozen over that time frame. All used daily.
stagger87··on Microsoft lets bosses spot teams that are dodging Copilot
I seem to remember a similar arc with Cortana. Didn't it briefly appear everywhere in MS365?
stagger87··on Philz Coffee close to closing deal to sell to private equity firm for $145M
I agree with you and don't know enough to speak authoritatively. That being said, I did find this definition of liquidation (below). The article hints the business was in trouble, the way I'm reading it, if the sale doesn't cover all obligations, its would be a liquidation.

"Business liquidation involves selling off a company’s assets, such as equipment, inventory, and real estate, and using the proceeds to pay off debts and obligations. This process usually occurs when a business is no longer profitable, facing insurmountable financial challenges, or the owner decides to retire or pursue other opportunities."

stagger87··on Philz Coffee close to closing deal to sell to private equity firm for $145M
"In a liquidation, common stockholders receive whatever assets remain after creditors, bondholders, and preferred stockholders are paid."

Coupled with what sounds like an already bad financial state of the company... I'm not claiming no foul play, but it looks like there is a reasonable avenue for what is happening.

stagger87··on Rising graduate joblessness is mainly affecting men
> "young people collecting disability."

Can you elaborate?

stagger87··on Inside the box: Everything I did with an Arduino starter kit
There is no one way to learn electronics. The Arduino will hold your hand through lighting up an LED, but depending on how much depth you want, may not teach you how it's happening. Working with an Arduino is like bowling with bumpers, which is a good place to start.
stagger87··on Every 5x5 Nonogram
Not OP, but you don't ever have to guess and backtrack, you can always work out the next move. After playing about 100 boards several simple "rules" emerge which allow for this.
stagger87··on 'I found your dad': The mystery of a missing climber
That's fair. If you use any of the numbers closer to the activity described in the article (mountaineering at 22k') then you see the disparity. Even non elite mountaineering (mt ranier at 14k') has twice the mortality rate, according to this data.
stagger87··on 'I found your dad': The mystery of a missing climber
Even a cursory glance of mortality rates for driving vs mountaineering show orders of magnitude higher rates for mountaineering.

stagger87··on Perplexity Deep Research
> You are a bit behind.

Quite the opposite. I'm familiar enough with these systems to know that asking the question "List the college majors of all Fortune 100 CEOs" is not going to get you a correct answer, Gemini and you.com included. I am happy to be proven wrong. :)

stagger87··on Perplexity Deep Research
Hopefully the end user of these products know something about LLMs and why asking a question such as "List the college majors of all of the Fortune 100 CEOs" is not really suited well for them.
stagger87··on Quiet Quitting: Why Employees Are Demanding Fairness and Boundaries
Working on weapons is important to maintain the freedom to be disappointed in others working on weapons.
stagger87··on Can SpaceX land a rocket with 1/2 cm accuracy?
Well, to be fair, the engineers working on this system have been thinking about the accuracy this whole time even if you haven't. Even on the first go, it still had to land on a relatively small pad floating in the ocean.
stagger87··on Mira Murati leaves OpenAI
It's in nobodies best interest to do this especially when there is so much money at play.
stagger87··on Marketing to Engineers (2001)
I suspect you're overthinking it. Consider the difference between someone wanting to know the technical specifications of an iPhone and the electrical engineer wanting to know the technical specifications of a resistor they want to use to build the iPhone. The marketing efforts for the iPhone and resistor should be different. Replace "electrical engineer" with anything you want and it still can work, for instance, how about a marketing person that wants to know the specifications of some cardboard materials when designing the product box for the iPhone. No longer engineering but the marketing for the cardboard will probably look more like the resistor than the iPhone.

It's really the product and it's intended use case that's driving the audience, which the link is just generalizing to "engineer".

stagger87··on Nasir Ahmed's digital-compression breakthrough helped make JPEGs/MPEGs possible
EE and CS are both going to be where the "rubber meets the road", or the application of these concepts, especially at the BS/MS level. Specifically in classes covering things like communication codecs, video/image processing, signal processing, and compression. If you're interested more in the foundations of these ideas, you really need to look more towards pure math. For instance, the beginning of every coding book I own starts with a review of abstract algebra, and lot of signal processing ideas are built on top of complex analysis.
stagger87··on Zen5's AVX512 Teardown and More
Seeing 2 consumer CPU generations in a row not only support but improve AVX512 capabilities will hopefully go a long ways towards regaining the confidence of the developers that use AVX512 in the consumer space. I know I personally have been holding back as I watched Intel fumble AVX512 for the last 10 years. With their even more recent fumbles there could be a near future where AMD CPUs have majority market share in both desktop and mobile. Great news for developers that can use AVX512.
stagger87··on Every company should be owned by its employees
In an ESOP, stocks are not normally fungible and cannot be traded easily. Usually they are bought back post employment. In my case I was able to either get cash or have it put into a 401k.
stagger87··on Every company should be owned by its employees
In an ESOP, employees typically own 100% of the stock.
