I know right? Almost like it should be called Spaceballs II: The Search for More Money.

On low end CPUs you can max out the CPU before maxing out network---if you want to get fancy, you can use rsync over an unencrypted remote shell like rsh, but I would only do this if the computers were directly connected to each other by one Ethernet cable.

I have one, it's been great.

That said, "exactly what the problem is" isn't always the same as telling you the solution. I had a "misfire on cyl #3" error or something like that, which can be a number of things. Replacing all the coils and plugs myself was probably still cheaper than taking it to the shop though!

Not sure I agree.

First, stocks tend to be highly correlated with "the market" (see financial "β"/"beta coefficient"). For example, look at, say, The Home Depot or Ford Motors. From January 2000 to January 2003 (spanning the dot com bubble) they each lost about a third of their value, yet these are not "dot com"-centric companies.

Second, the promise of AI is that it will help every company that has desk jobs. So every company has this expectation now priced into their stock, and if the bottom falls out, well...

Not an analyst/I don't pick stocks, but just my 2¢.

If you're running it via docker compose it's trivial to upgrade, and there are no breaking changes. Pull, down, up, you're done.

In grad school I bought a blue (405nm) laser pointer. It was supposed to be <5mW, but I measured it at over 70mW.

When I criticize my baby, he looks me in the eyes and asserts dominance with a "what you gonna do about it?" shit grin.

Comparing him to Stephen Miller is just offensive.

I think "boring" (making a hole with a revolving but) in the title is a pun on this...

Prescriptive vs. descriptive is different in colloquial language than in science.

If my data logger captures 1kB/km, how many bytes/meter is that? In every other quantitative unit I can think of, the k should cancel out; but if you want computers to be special, that's your preference.

Metric sucks. Powers of ten are arbitrary, a fluke of biology. Powers of two are the only sensible way to make a system of measurements.

Then why are you trying to shoehorn binary into decimal? As in: why are you using decimal prefixes in the first place? Answer is probably that most people have intuition behind powers of ten. You can easily express in log2-bytes instead (a GiB is 30, a TiB is 33...etc.). Be the change you want to see!

I'm born and raised in the USA, and while imperial units can be handy for a few every day tasks, there's a reason why the sciences in the US tend to use metric.

Regarding cooking, I'll stick to metric, measured by weight. I can double, halve, or multiply my recipe by pi, and all I have to do is look for a different number on my scale.

My favorite is habanero


there's no ñ, just n, but some will make a show of pronouncing it with the incorrect ñ sound.

Giga, Mega, Kilo...these are all SI prefixes; they differ by a factor of one thousand, which is very clean in base ten.

Ten in binary systems isn't special, but two is; and two to the ten is very nearly a thousand, and a thousand separates the major SI prefixes. This is a neat coincidence, but should not IMHO change the meaning of the prefix.

Metric units are awesome in large part because of the use of prefixes; messing up the meaning of prefixes is a disservice to the SI/metric system. Giga == billion independent of the context. A light-year is close to 10 petameters, but no one would claim it's exactly 10Pm.

Now, if you want to call it an "imperial gigabyte," by all means...

The crazy thing is, d-limonene can be used as a paint thinner, you can burn it in a diesel or a jet engine, and when ingested it can reduce heartburn.

 

People often complain about San Francisco's public transit


and to be sure, it's not perfect by any means (multiple separate agencies doesn't help). But the historic streetcars are pretty neat!

They're painted with the livery of various historic streetcars from all over the country (and a few international, I think). Best of all, they run alongside the modern fleet


same route, same fare.

 

Noticed a few days ago that Sutro Tower's red blinking lights are now white. Just asked them on their website form, but wondered if anyone else knows the story with this.

Personally, I miss the red ones!

Howdy!

I got my Technician in early 2000s, and last year finally upgraded to Extra. Looking to set up a very basic shack.

I'm looking for an HF setup, with most of my use probably using digital modes, but would like the ability to use voice.

Current transceiver is on loan from girlfriend's dad, a Ten-Tec Scout 555


50W HF unit with separate modules for each band. One limitation of this is that the modules set the mode, so it's LSB on 40m, making e.g. FT8 not possible (without some hacking of code or perhaps hacking the module).

Antenna is end-fed with an off-the-shelf 49:1. Currently only have 20m half-wave, but have just enough room for a 40m half-wave in the attic, which is the ultimate goal.

For digital modes, it looks like there are sort of 3 classes of radio:

  • "full digital" where the radio has e.g. a USB port and handles audio, transmit, and frequency set.
  • Some computer-control with RS232, but uses computer audio+adapter to transmit.
  • No digital, use adapter to transmit. This is what the current setup uses (and it works great!)

I'm leaning towards a conventional transceiver, e.g., something from ICOM, Kenwood, Yaesu, (or others) rather than an SDR unit. I'd like the ability to go up to 50-100W if possible.

I don't have a hard-and-fast budget; would like to keep it <$1000 if possible; mostly just looking at used transceivers. Something like a Kenwood TS-590 looks pretty amazing and very "plug-and-play" (but pushing up against price). Something like a Yaesu FT-920 looks pretty feature-rich too; and even something more affordable like an ICOM 706 or even a 725 is probably more radio than I need. Or just grab a new 7300 and call it a day!

Anyway...clearly, I don't know exactly what I want, but figured I'd ask folks with more experience if they have any wisdom. Thanks!
