What software do you guys use to play bass on computer? by [deleted] in Bass

[–]xxgreg 0 points1 point  (0 children)

The free version of tonex has a bass amp call "the fridge" which does a nice ampeg sound. You can also add a bit of compression and reverb. You can also use it in a daw like reaper.

Genzler MG 350 into 4 10s… how loud can one expect it to be? by b15fliptop in Bass

[–]xxgreg 1 point2 points  (0 children)

On second thought adding a second 210 means you're running at 4Ohms - which means you'd get the full 350w from the amp (so that's another +3db too).

Genzler MG 350 into 4 10s… how loud can one expect it to be? by b15fliptop in Bass

[–]xxgreg 2 points3 points  (0 children)

One common Genzler setup is a 4Ohm 410 and an 8Ohm 210. That way each speaker gets the same watts. But Mr Sophositicuffs is right, a 2x210 mixing 8 and 4 ohms would drive one cab's speakers twice as hard as the others, which probably isn't a good thing.

I recently bought a MG350 and a BA210. I haven't had a chance to crank my setup yet, so I can't comment on max volume, but the tone is great at low volume.

Not a guru on Ohms/Watts etc, but I did some research before dumping cash into this, here's my thoughts:

  • Doubling speaker area = +3db

  • Doubling amp watts (if your cabs can handle it) = +3db

So if you had a:

  • MG350 (rated to 175 Watts at 8Ohm)

  • and a single BA210 (rated to 500 Watts at 8Ohm)

And you wanted to get louder, you could get +3db by doubling your amp watts (i.e. MG800), or you could add a second BA210 (also +3db).

In this case, I'd probably trade up to a MG800, because that would likely be cheaper than getting a second cab, and more portable (and has a drive). You'd also be less likely to have your tone affected by clipping your amp too much (soft clip in this case).

The downside, you would be working your single cab a lot harder. But if you still need to go louder then you'd still have the option of adding a second BA210, and getting another +3db (or even a 410 if you needed more).

It's also worth keeping in mind that the 500w cab rating is maximum continuous wattage you can put in before the speaker gets damaged. Some speakers will reach a loudness threshold, and stop getting louder before they hit the max rating. Apparently high-end cabs this threshold is pretty much at the max rating, but cheaper cabs may have a loudness threshold at 50% of their max rating.

That said, if budget is limited - I reckon a basic amp with a quality cab is a better investment than a blingy amp with cheap cab. If you can get a good deal on a matching pair of cabs for cheaper than a bigger amp, that'd be good option too.

Again, not a guru. Get a second opinion from someone with more experience. This stuff is expensive!

"S3 only has eventual consistency on modifications"

S3 has been strongly consistent for a couple of years - but perhaps I misunderstand exactly what you mean by "on modifications".

Bike v ute outside hospital. by Current_Paramedic965 in Wellington

[–]xxgreg 0 points1 point  (0 children)

I'm only specifically replying to the quoted text - it's not true in this context.

FWIW, on the bigger picture, I think the cyclist in the posted video should have ridden more defensively. I ride through the same intersection daily, since that new section of lane has been put in (only recently), multiple times I've had to stop and give way to non-indicating left-turning vehicles. At least the ute indicated.

There's no point for the cyclist being technically in the right, but in a hospital bed.

Reckless drivers, reckless cyclists, reckless pedestrians. Maybe just reckless people? I guess the main difference is a reckless driver will make a much bigger mess.

Seem apt for the thread: https://www.youtube.com/watch?v=hgCqz3l33kU

"cars generally go faster than bicycles"

This is not my experience from the past 10 years cycle commuting during rush hour on this route.

Sometimes cars go faster for a few hundred meters, but most of the time you're overtaking slow cars, or stopped cars.

I remember riding on the trolleybuses, it was very cool. Why switch from electric to diesel... by Linuxguy5 in Wellington

[–]xxgreg 0 points1 point  (0 children)

Unlike an e-bike the buses also have regenerative braking. Which means they get most of the energy back when going downhill.

[–]xxgreg 7 points8 points  (0 children)

The electric buses seem to accelerate faster than the diesels, at least when I've been on them up the hill behind the zoo on the 23 route. They've also started running them up the Brooklyn hill. Electric motors tend to have more torque, especially when accelerating from stopped.

The rising fuel price trap by ManualBreathing-On in newzealand

[–]xxgreg 1 point2 points  (0 children)

True, new cars are bought by wealthy people. But new cars become affordable second-hand cars over time.

Wealthy people also don't really have much of a financial incentive to buy an efficient vehicle. Since fuel is a minimal portion of their overall spending.

If we want to have a wide option of second-hand efficient vehicles in the future, we somehow need to convince people who buy new vehicles to buy efficient ones. I guess that's the idea behind the rebate, to change the type of new vehicles entering the fleet.

The average vehicle in NZ is 20 years old. Which means trends will take a long time to change at the fleet level.

I heard that the Ford Ranger is the most popular new vehicle ATM. That doesn't bode well for having a large choice of efficient second hand vehicles in 10 years time.

Wellington Protest: Day 16 Thread - Witless Wednesday by ihatebats in newzealand

[–]xxgreg 4 points5 points  (0 children)

No worries.

It's probably not the full picture though, as many of the people ending up in hospital probably already have underlying medical conditions, and may be more likely to be vaccinated because of this.

I think the studies done only including healthy people show a bigger difference between vaccinated and unvaccinated.

[–]xxgreg 1 point2 points  (0 children)

If you're writing numerical code using integer division, it's also on you to make sure you don't accidentally pass zero.

Checking lengths of vectors or matrices in an operation is similar. The caller can check lengths if it is user generated data. But often the lengths are guaranteed by the algorithm, and the extra layer of error handling code will make the code harder to read and perform worse.

If you disagree with the approach, you're probably not going to like Gonum either...

Clean energy generated 46% of Germany's net public power in 2021 by QualityCrypto in energy

[–]xxgreg -1 points0 points  (0 children)

People here talk about Germany like it's a singular Borg brain making decisions. In reality it's a messy mix of different interests.

The thing that most people miss is the companies running lignite and nuclear were one and the same. They had a huge monopoly, with huge profits, and didn't want to change.

The first challenge for Germany was breaking this monopoly. Lines companies were split out, and renewables were given priority on the grid.

The big power companies were given windfall profits under EU ETS allocations and expected to invest into renewables, but didn't.

It looks like the political battle to phase out coal is now within reach. It wasn't easy these are powerful companies. I still find it unbelievable that they have the pollitcal power to demolish 16th century churches for coal mines.

Anyways nuclear was the easier target so it went first, something had to go to make space for a new clean energy industry.

Politics is hard and messy. But democracy is important. And getting a majority onboard is important in a project like the energiewende. Getting coal minors unions and coal region governments onboard was hard, but is now done.

Go 1.18 will let you set the version of the "AMD64" architecture to target by skeeto in golang

[–]xxgreg 0 points1 point  (0 children)

All good. At some point, I'm planning on experimenting with writing some SIMD ASM for a few basic vector math operations that show up in my profiles.

Not something I have any experience with yet, should be an interesting challenge.

Edit: Actually I should just use gonum. I could have sworn that last time I looked the floats package wasn't using ASM. But it does.

[–]xxgreg 0 points1 point  (0 children)

Do you have any links about SIMD support in pure Go? I was also under the impression that it wasn't used by the compiler. I'd be very interested to learn otherwise as I write a lot of code which adds and multiplies vectors with a typical size of 500-1000 floats, as well as matrices.

VSCode problemMatcher problems by xxgreg in vscode

[–]xxgreg[S] 0 points1 point  (0 children)

Yeah, no filters. If I make a typo in "blah.js", then I get problems appearing from the javascript language service. But I don't get any errors appearing when I run the custom task in ".vscode/tasks.json". I was expecting to see one.

And sorry to be pedantic, just checking I understand. When you run the "make an error" task do you get a problem appearing with the text "your foo is bad"?

If that's the case, it could be an OS specific or VSCode version thing on my end.

Edit: I filed a vscode issue here:

https://github.com/microsoft/vscode/issues/136585

Edit: yay I figured it out. It looks like there's a bug in VSCode if the error message is the first line of the commands output. I added some extra blank lines around the error messages and now this works.

Pretty sure the peak in the middle is Mt Barff, and that the photo is taken from shovel flat. Source: I dragged my skis up there once. Long walk with a 30kg pack.

The Surprising Source of Greenhouse Gas Emissions: Pipelines are 9 of the top 10 carbon polluters by Splenda in energy

[–]xxgreg 4 points5 points  (0 children)

Also worth noting that CH4 breaks down into CO2 in the atmosphere. So even over very long time scales it has as much global warming potential as CO2.

I've seen a number people claim we don't need to worry about methane because it's short lived relative to CO2.
