crazyjncsu··on Who makes the most reliable new cars?
That’s what I thought too, but it’s not the case.

The transmission of a traditional ICE vehicle is a component commonly prone to failure due to reliance on clutches, friction couplings, gear engagements, etc.

Hybrids replace this transmission with one composed of two electric motors and planetary gear sets. One or both of the motors also act as generators. It’s complex, but the highly variable speed of the output shaft is managed almost purely by torque splitting of the planetary gear sets along with routing of electrical energy within the system— no clutches or gear disengaging/reengaging.

And the ICE engine itself has an easier time (often Atkinson cycle) because the electric motors can provide much of the responsiveness to immediate power demands, allowing the ICE to operate in a much less stressful power band.

crazyjncsu··on ZF makes magnet-free electric motor uniquely compact and competitive
Maybe not your experiences, but, to me, their transmissions:

* hastened the inevitable transition away from manual gearboxes in cars

* gave a bit of a “last hurrah” to ICE powertrains in general

Quick-shifting, gobs of gears, lockup torque converters, and reliable to boot. I don’t hear the word “slushbox” being thrown around like it was previously to describe automatic transmissions. And I credit it mostly to ZF.

crazyjncsu··on Amsterdam to use “noise cameras” against too loud cars
I don’t know about that. I have an older sport quad ATV. Loud AF with custom exhaust the last owner installed. I have full control of the fuel delivery with the carb mixture/jetting/etc, and there is no nothing other than preventing backfiring/popping that has any effect on the noise. I even tried repacking the “muffler” with new stuffing—- didn’t help.

To be fair to those people, they also don’t think you need your plywood and mulch because you should live in a nice little apartment with a surely altruistic landlord who takes care of every need that the plywood and mulch could satisfy.

I did not, but I was only looking for 25 year old trucks as that is the age requirement for import.
crazyjncsu··on Rural Americans are importing tiny Japanese pickup trucks
I’m Jake from the article.

The trucks have all just gone through auction and have inspection reports. Mine I bought for $2k was grade 3.5 and what I’d consider pristine for a 25 year old truck. The Japanese are pretty trustworthy people to do business with, and they build great vehicles.

One thing the author left out was the fascination I had with the whole process. Watching auctions, assignment to a ship, tracking it through the ocean and storms and watching on video as it passed through the Panama Canal. Then the customs and importation paperwork with CBP, going to the port, the driving 200 miles home in my new “truck” that had road manners more akin to my golf cart than anything actually on the road around me. I-95 was terrifying— I barely got off the on-ramp before looking for the next off-ramp to find backroads for the rest of the journey.

crazyjncsu··on Corpse Flower Bloom
I’ve seen a couple of these blooms—- first at the NCSU Plant Biology greenhouse and then at Tony Avent’s Plant Delights nursery.

Both were spectacular. Neither smelled at all.

I think the smell may only last for a short period, likely before the bloom peaks. We didn’t want to jump the gun on the bloom, so we visited a day after we heard it bloomed.

crazyjncsu··on Ivermectin: Much More Than You Wanted to Know
That’s certainly already the case. Ivermectin has lost effectiveness against particularly insidious parasites such as Haemonchus Contortus (barber pole worm). We’ve resorted to other treatments such as Moxidectin, Levamisole, etc, all of which are more expensive and harder to dose safely and effectively.

I can totally understand how Ivermectin got its following— it’s an amazing general purpose medicine around the farm. I generally use it responsibly by verifying the presence of parasites before administering (which can be literally any animal on the farm with almost any parasite) … but then there are times such as when my daughter had a single pet chicken (among many healthy ones) that wasn’t looking so hot … Whereas previously I’d just dispatch the animal and be done with it, now I give a dose of Ivermectin and isolate for a few days before calling in the grim reaper. So far the success rate is something like 90% where now my 9 year old daughter administers it herself. While I acknowledge this isn’t the most responsible, I can imagine others have had similar experiences which explain some of the popularity of Ivermectin with rural folk.

crazyjncsu··on Western Digital confirms speed crippling SN550 SSD flash change
Nothing new folks. 23 years ago I bought a RIVA TNT video card (https://en.wikipedia.org/wiki/RIVA_TNT) where early models (and, conveniently, the ones sent to reviewers) were clocked at 110Mhz. They silently clocked them down to 90Mhz after a month or so before I got mine.

“The TNT shipped later than originally planned, ran quite hot, and was clocked lower than Nvidia had planned at 90 MHz instead of 110 MHz. Originally planned specifications should have placed the card ahead of Voodoo2 in theoretical performance for Direct3D applications, but at 90 MHz it did not quite match the Voodoo2”

I’ve been a bitter man ever since…

Which would be great if any other state had the weather and beauty of California. And California is fucking huge to boot. Not initially splitting it up into multiple states was one of the biggest mistakes in this nation’s history.

The people answering your survey probably weren't aware they could power an entire jobsite with just a truck. Killer features such as this will be how electric vehicles penetrate the holdouts.

crazyjncsu··on Is that ship still stuck?
I expect dredging will be the main solution. Dredges are just slow moving, so they’ve taken a while to arrive.

I’d also expect some long reach excavators and/or draglines to be working from the shore and/or barges.

They probably just underestimated the stuckedness at first. Throw in some ineptitude and corruption, and you have this royal mess.

crazyjncsu··on One of OVH's datacenter in Strasbourg, France is literally on fire
We had a bunch of servers get taken out by this. We were able to failover with backups from the last 12 hours.

The incident sounded suspicious from the start, but the wording “could not control the fire in SBG2” sounds very ominous ... Chernobyl-y even.

And seeing the compactness of the entire facility (https://baxtel.com/data-center/ovh-strasbourg-campus/photos), it seems an uncontrolled fire could take out all three buildings in short order. I’m very interested in seeing the damage and postmortem from this one.

Also interesting they tout all sorts of sophistication (https://www.ovh.com/world/us/about-us/datacenters.xml), but no mention of fire suppression

When did he engage in "explicitly invoking a politicized definition of the word merit"?

I'm very new to the understanding that the word "merit" is now politicized, and I find it very unfortunate.

For the sake of humanity, I would hope that at least the _definition_ of "merit" could be commonly accepted..

crazyjncsu··on Print this file, your printer will jam (2008)
Just so the laymen here don’t think this is some kind of hack, this is what is referred to as “rotating your tires”, which should sound familiar.

The problem is that tires are often not rotatable due to staggered setups where the front and back tires are different sizes (very common) or due to directionality of tires (less common).

crazyjncsu··on 1937 film explains how a car differential works
They aren’t needed in fossil fuel based cars either if you have an engine for each drive wheel. But most electric cars still employ a differential on one or more axles, even Tesla. Typically, due to cost, packaging, or performance, you have more drive wheels than motors and a differential is necessary.

The problem is when “no abuse is acceptable” and at the same time we continue to redefine these types of terms to apply to lesser and lesser offenses.

I personally am tired of working at a firm where everyone has a voice that they’re always using.

crazyjncsu··on Carmakers want to ditch battery packs, use auto bodies for energy storage
The news to me is now arstechnica.com is syndicating content from wired.com ... And as far as I'm concerned, no good can come from that...

... starting with this article which gives credence to these Asp and Greenhalgh fellows, who have deemed the current situation with batteries as a "structural parasite" while at the same time proposing to incorporate them into the skin of the vehicle, which moves mass way upwards and way outwards-- both of the no-nos in regards to stability. The negative effects from just the shifting of mass will likely outweigh any of the gains using their method, which so far seem to be a bit nebulous. And that's ignoring many of the obvious safety, reparability, and complexity concerns...

> Waterproofing has to go on the outside surface to work.

He was fixing cracks, which is effectively waterproofing, and it did work, locally, as he mentioned the water was "rerouted".

It works like this:

- Injection ports are adhered and spaced along the crack.

- Epoxy is smeared along the crack from the inside, providing a temporary seal for the next step.

- Epoxy or polyurethane is injected into the ports, starting from the bottom and progressing upwards as material seeps out of the ports above

This works, but this guy just didn't take it far enough, probably for good reason.
