One of the radio links in my network was down for 3 hours a few days ago. Why? An unintended interaction between parameters on the Ubiquiti radio on the client side of the link collided with a DFS radar detection event on the access point

On GPON or XGSPON, sending 1490nm on the upstream will have no effect unless you get to incredibly high power levels where they cause damage to the transmit laser on the OLT's optics for GPON (many dB higher for XGSPON). Fibre optic c

The opioid epedemic likely contributed as well. Opioids are not exactly conducive to dancing all night. The MDMA supply in Toronto was turned off overnight when the guy that processed barrels of chemicals at one of the chemistry labs at th

There were still underground events held in parks and other unofficial spaces after the regulations came in; I attended a number of small events by Moonshadow and others. Black Light Activists kept going with a regular dose of psytrance, a

In Toronto the decline of the scene in the late '90s was accelerated significantly when the city clamped down on promotors by restricting them from renting venues on city owned property. This was after gradually requiring EMTs and inc

I lived on 36 hour days for a good year or so as well. It made being social very difficult, and was not the greatest thing for me overall, although I did get a lot of code written. A few months ago I finally got a CPAP machine after gettin

It's hard to determine without meaningful regular/frequent interaction, and by that I mean more than just a weekly phone call to catch up on things. I've been watching my father's interactions with one of his older brot

This is a comment I've seen a number of times, but I really don't agree with. All C is constrained by the compiler that you are using, and there is no way to ensure code written today will work exactly as expected 20 years down t

Linking is a skill that's worth picking up if you ever intend to do system level things. I ended up learning the basics in a few different projects: back in the days of 8 bit systems using DOS and real mode 8086 applications, segment

I think that Intel being split up into separate design and manufacturing firms might well be the optimal path forward. It is quite clear that AMD did the right thing when it spun out Global Foundaries 15 years ago. Were Intel to do so, th

The US military will never be the "biggest customer" of a fab. The only true volume products the military needs are bullets. For reference, Intel CPU sales are on the order of 50 million units per year. As a comparison, Apple is

1 "good" process node does not a trusted partner make. Leading edge semiconductors have design lead times measured in years. This means that the design decision for what fab to use for a given product that is being manufactured

Even if the 18A process is awesome, that doesn't help without the right product(s) to run through the fab. Have a look at the graveyard of firms that tried being Intel Foundry customers over the past 15 years. Achronix was the perfect

My biggest disappointment with C++ is that the standard libraries are completely unsuitable for use in embedded systems where you have to control when, where and how many memory allocations occur. This is particularly important when the sy

Not in the embedded space. When you've worked on embedded systems long enough, you learn that you have to accept the compiler that the vendor provided you with, and you adapt your codebase to the limitations of that compiler. This me

Except that it's not just "providing information" as it does not supply information to both the buyer and the seller. In a stock market, both the buyer and seller see the range between bid and ask, and historic prices are re

I was referring to gcc bugs. Doing Linux kernel development 20+ years ago certain complex functions with lots of register spills would occasionally trip up gcc's register allocator on i386. Architectures with more registers and less

Alas, since the author only looked at the past 20 year it misses out on the time when alternatives like Enlightenment [ https://www.enlightenment.org/ ] were shipped in Red Hat Linux. I have fond memories of the cool eye can

Alcoa and Phinergy demonstrated an aluminium-air battery over a decade ago that enabled 1600km range. The downside is that it had to be swapped out and recycled after it was spent (which explains why Alcoa's interest since it would ga

Is it worth the risk? Any company buying Intel would have to deal with the internal cultural rot that has taken hold. Would the buyer be able to survive and make things better or would it turn out like the McDonnell Douglas merger with Bo

However, subsidies always come with requirements for companies to fulfill. While it may sound great that Intel is getting billions of dollars in money to build and operate new fabs in the US, those fabs come with massive operating expenses

In my experience, if your variable names are long enough to overflow an 80 column limit, you've probably already got a problem. Longer variable names have a cognitive load in and of themselves, which, to me, usually means someone didn

Modern NICs will do that for you via a feature called TSO -- TCP Segmentation Offload. More shocking to me is that anyone would attempt to run network throughput oriented software inside of Chromium. Look at what Cloudflare and Netflix do

Yes, even in single mode fibers light is bouncing around between the layers of glass with different diffraction indicies. The pulses just aren't dispersing while doing so.
