The RAM heavy duty pickups have a system like this, where it's a lot harder to prevent or cut down noise of a big diesel engine, HD transmission, tcase, and tires. It really works well in practice.

One thing that makes it hard to grok is how large the scope seems to be and the cognitive bias many devs have developed against new platforms due to being burned in the past. It reminds me of a throwback to 90s era RADs that wanted to enco

With my FreeBSD ports maintainer hat on, I don't see a 2.0 tag in github, was this blog premature?

Setting boundaries on what one will and wont do isn't victimhood. He doesn't owe the world his output under any terms but his own.

Just since it's sponsored, Airstream is one of the shittiest luxury products I can think of and owning one of the bigger mistakes I've ever made. The quality is the same as any other RV, so you are paying a huge premium for the a

I always am curious when I see this. I've planned and deployed master setups in two separate 10^4 node count companies now. In my experience the number of hosts doesn't really matter (figuring out an architecture that will work

I've generally seen the opposite, salt works well multi0-platform, ansible is geared toward the LTS distros. It's extremely easy to get bug fixes into salt, and I've done a few dozen. The biggest issue I see with ansible is

The tech industry, but especially and most drastically open source, has been completely taken over by expert marketers called "dev relations" in the past decade. What you say about working too well is true; the business model of

Apple has had the performance per watt crown for quite some time. These chips are not very good for anything outside of prototyping, otherwise hyperscalers would run a sea of small nodes.

illumos concern trolling, this has nothing to do with engineering leadership and is just lashing out a bad faith personal attack because you are friends with joyent people. Being unable to acknowledge that he served his sentence and is ref

Brian Behlendorf and Matt Macy are both fantastic engineers, other people contributed but this is ultimately the kind of thing that must be led by a small number of (in this case two) extremely senior engineers working together for a common

Surprising, I thought RH had drawn pretty clear lines in the sand in favor of evolving XFS to be the universal disk FS for Linux.

In C, because you often use void * for containers, there may be less code bloat than a container multiply used using generics which accessors are monomorphized for each type. In practice this is pretty trivial difference and can be bounded

By the time you subtract all the sub-prime performance from their vulnerabilities, this isn't actually true on properly patched operating systems. They took a sub-prime loan on validation, sacrificing security in the process, and the

Wireless technology is a patent minefield. CPUs generally aren't because the techniques for internals are old, and internal design, manufacturing, and especially validation (where intel fell flat lately) methodologies dominate the cos

I know at least HP, IBM, and Sun had comprehensive X terminal strategies. I think this predated that with for instance cut down 7012s or the 7011-220 RSC (single chip POWER1) pizzabox.

I would have used VIOS for that situation and passed the PCI device through to the LPAR for most the work. It would be about 5 minutes if you had reasonable disks and you could just barrel fish several cards and LPARs for intense debugging

The beauty of OpenFirmware is that it is extended with Forth, which is extremely compact (so could fit on small PROMs in the computer and fcode for addon cards). If you are designing a PCI card, you can write a bit of fcode that will run o

eBay sellers are often silly (I miss when it was an actual auction site instead of a shitty amalgamation of Amazon's 3rd party sellers and craigslist) although a lot of these vintage UNIX machines are now worth at least $100USD or more

I am always surprised by the negativity that surrounds AIX by layperson UNIX users. AIX actually remains ultramodern when the full timeline is taken into account of remaining UNIX-like OSes like Linux, Solaris, and the BSDs. There's

I have actual 3174s with FICON attach for my 9377 and z800. Also have a Memorex-Telex 3174 clone. They are interesting machines in themselves. It's appropriate to think of a mainframe as a distributed system of sorts, where these co

Very interesting observations, thanks for sharing. Can you share any continuation of thoughts into the present and near future? It's hard for me to see what is driving current "tech" culture. I'm loath to even call it t
