Another important fact about me is that I collect ISA cards. I still don't believe in magic- just concepts I don't understand yet.

100/1000baseT1 to baseT media converter schematic done and review complete (although if anyone else wants to have a look, the sch is at https://www.antikernel.net/temp/baset1-media-converter.pdf).

181 components, pretty small compared to most of my recent designs that are pushing well above 500.

Starting layout now, should be pretty straightforward.

@azonenberg I subconsciously read this as 10BASET to 10BASE2 converter, and I thought:

  1. Well, that's trailing edge for Andrew.
  2. 181 components? I didn't know you could practically do a converter w/ discrete only.
  3. Then I see the ICs.

Ahhh, makes much more sense now :D.

@cr1901@mastodon.social avatar

@azonenberg I have thinnet because I accidentally* bought a bunch of 3c509 cards off Ebay that didn't include a 10BASET port.

I decided to make do, and over the years have gone through various hubs and 10BASE2 to T converters to keep my vintage fleet online.

At least RG-58 cable and BNC tees aren't in short supply.

  • The listing either lied about which version of the cards they were providing, or I just didn't see the lack of port. It was late 2010, I don't remember.

@azonenberg Looks up Haswell... yea, that's a reasonable trailing-edge to have.

The leading edge I have at home is a Skylake i7 of some sort.

Gonna be honest, when it came time to buy a computer last in 2017, I just used an Acer recommendation @regehr gave me a few months prior LOL.

(Works just fine, other than the PSU having to be replaced.)

I feel like the fact that Tesla batteries are having problems in colder regions is a perfect "hoisted by your own petard" moment, given that Tesla's whole thing is ignoring a century of industry experience and good practices in order to "disrupt the market" or whatever, whereas industrial engine manufacturers solved this exact problem years ago by supplementing their primary lithium batteries with a small AGM to run a preheat cycle.

question: given rsync.net's features and pricing, is there any reason to use tarsnap at all?

cr1901,

@whitequark I remember someone in IRC got a $500 lifetime deal. If you are able to get such a deal, please send it my way :P.

cr1901,
@cr1901@mastodon.social avatar

@whitequark Anyways, I'm very partial to borg and rsync. I've not felt a reason to use tarsnap.

The site seems a bit dodgy/minimal, but they say they've been around for 20 years.

I would say it's worth the risk. P(you_losing_local_backup_in_time_period ∩ them_folding_in_same_time_period) is probably pretty low.

Bar for time travelers. A programmer from the 21st century is complaining about bugs caused by time zones. A programmer from the 31st century scoffs and starts talking about bugs caused by relativistic time dilation. Next to them, the guy who writes the firmware for the time machines is grinding his teeth

@azonenberg NJ DOT has some pretty horrendous bot detection, that makes me go through like 5 "find the traffic lights to train the UI" prompt.

cr1901,
@cr1901@mastodon.social avatar

According to Wiki, Eastmancolor was early 1950s. The linked short was ~1936-37. AFAICT, when Paramount sold of it's cartoons to U.M. & M./NTA in the 50s, they created 16mm Eastmancolor prints for television. These prints had to have a further amplified red to be compatible with dodgy B&W equipment at the time.

I wonder how hard it would be (and how you would) design a program to have reproducible memory addresses.

like "address space unrandomization"

cr1901,
@cr1901@mastodon.social avatar

@foone Run it on DOS 2.x on your IBM PC :P.

(In all serious, I was able to get consistent memory locations using this method when developing https://github.com/cr1901/devdriv/. DEBUG.COM has a "search memory space" command.)

I have a Python script in which I have an assert. The assert is always true; that's why I'm asserting it. The assert is a canary in case I change a constant in one place without changing code that depends on it having that value.

Python 3 gives me a warning that the assertion is always true. That's annoying. Can I turn the warning off?

/path/toplevel.py:10: SyntaxWarning: assertion is always true, perhaps remove parentheses?
assert(VID_V_ACTIVE == 144, "constant different from expected")

cr1901,
@cr1901@mastodon.social avatar

@mcc IIRC, asserts don't have parens in Python. I.e. "remove the parentheses and the warning will go away without changing the meaning of your assert".

So Broadcom, the new VMware owner in less than a quarter changes the licence model to subscription only, and kicks out most service and sales partner, informing them on the quick that their contracts will be terminated and not renewed. Or perhaps, nobody exactly knows.

That literally screams build your business on closed source products, doesn't it?

They call the anti business , but somehow the mainstream is quite okay to overlook unacceptable behaviour from the big players?

cr1901,

@yacc143 @koz Broadcom is a cancer and RPi is a thinly-veiled advertisement for Broadcom IP.

For the last year I've been semi-daily posting "What I'm Listening To Today" links in this thread:

https://mastodon.social/@mcc/108199886340178151

The thread is now so long it is increasingly breaking Mastodon, so I am making a new thread, starting here.

To recap, here's the entirety of the year-one thread in the most impractical possible format: A YouTube playlist containing 246 songs and running for just over 47 hours:
