I keep reading in posts here comments about Firefox as if they don't rate it as a worthwhile browser or am I just imagining it? If not, why don't you like it, and what do you recommend to use as a browser then?

Nah it's a secondary browser here for testing reasons for a good reason. It has some seriously fucked up things going on inside it. I actually spent an hour last week working on an issue related to Firefox which was resulting in cookie data being appended to over and over and over again until the server rejected the request. Of course as the dude responsible for the server this was my issue to deal with until I had proven otherwise :). This is due to a weird ass bug in Document.cookie.  I'm not joking i have opened over 50 bugzilla tickets against it. It's a shit show.

On the quality front it's the worst of all of the mainstream browsers now. I hate saying it but Chromium/V8 is actually rather good.

Edit: oh and the other one this week - wireshark and firefox dev tools don't always agree on what is going on over the network  >:(

This is the "why" from back when bd gave me the aghast look after I told him I was using FireFlumph again.

I countered that from a lazy end-user standpoint, it was much quicker now and generally less personally invasive. :-//

Oh, OK, I'll continue with it then because I admit that I like FireFox, it is far better than Chrome and MS offering.

It’s really like driving a well marketed rust bucket (there a shit joke hiding in there for anyone in the know) and claiming that it’s good for the environment but in fact it’s drinking more fuel than the modern cars. At the same time if you’re in a crash you’re fucked because the whole thing is held together with putty and sticky tape. But it doesn’t call home like modern cars.

That’s a through review of Firefox :)

Really the problem is there isn’t a good browser on the market and that’s because the whole html and http shebang is a fucking monumental shit show of hack jobs layered on top of each other for 25 years.

This. Pretty much all modern, mainstream browsers suck. And they suck because the browser vendors decided that the browser couldn't just browse... no, it also has to be a shitty, poor-man's version of an X-server and try to do application UI remoting, as well as being a shitty, poor-man's operating system unto itself, including f%@#ng assembly language (WebAssembly, I'm looking at you). Don't get me started on WebRTC, WebXR, WebGL, yadda, yadda, yadda. Any one of which might be fine ideas in isolation, but when you look at the sum total of all the bloat packed into modern browser.... UUuugggghgghghgghgh!!!! |O |O |O

Yeah, we tried to do the "standards-compliant" thing more than a decade ago... every ass-crack web dev and his cousin IT had conniption fits because their site was "optimized" with stupid workarounds that were essentially exploits of something broken in one or more of the popular browsers, and fixing it would literally require man-years of labor unfuckerizing multiple layers of shit going back to ie6. Or further.

Fast forward to now and that stupidity has multiplied exponentially with new layers of shit every couple of years or so to accommodate all the data-miners and built-in advertising and mental midget software engineers who think their website is made of unicorn poop that is how the whole world should be run... in all honesty, it's a wonder any website anywhere works at all for more than 5 minutes. |O

Man, that makes me sad. Grandpa died and that´s whats left over. At least the stuff goes to some afficionado.

Might not be. The dude I bought that Marconi 2019A off a few years back was having a mid life crisis and selling all his stuff to disappear off to the US with his new floozie. I thought it was an SK sale to start with  :-DD

I got a great deal on a nice DC bench power supply from a guy that was shedding his guitar amp- and guitar pedal-building dreams and getting ready to move to a new city after his recent divorce. It's a shame that so many great deals on TEA represent a loss of luck or life for the seller or the surviving family, but I guess that's true of anything of great value or utility. What I'm trying to say, is that if something bad happens to any of you, I can be be there with a trailer and a cash offer within an hour (if you are within driving distance)  >:D

W(here)TF are you?

Ulua is a genus of trevallies in the family Carangidae. They are native to the Indian Ocean and the western Pacific Ocean.

Something TE related and vaguely productive. Have updated OCXO module github project with KiCAD files. Took me a while to work out how to frig it to actually check stuff out in a state where KiCAD won't puke and I'm not 100% sure it still works with PCB footprints correctly. Link in picture  :-DD

I caught the Ulua a little bit north of Waimanalo. I think it was at Makapu'U

I haven't dared to go near KiCad and git together yet. In theory I want to but thankfully so far I've only been messing about and not got to the point where I'd feel uncomfortable moving on without version control. However, at my current rate I'm only a couple of weeks away from the point where I have to bite that bullet. I did start, a couple of weeks back, researching other people's experiences with combining the two but didn't get far - I'll have to get back to that. Any tips or tricks learned along your journey will be gratefully received here.

Yeah make sure you check in the library links file, keep any libraries local to the project and add all the bak and cache files to gitignore. That’s about it so far! Needs more testing as I’m not sure if full schematic / pcb sync works with the footprints I did.

On the Bench Tonight:

Testing a quick & dirty power pack for the headlamp on my fatbike. The headlamp is designed to plug into one of those Li USB/5V power bricks, and I have several such 1 cell power packs; however none of them will fit in my new hollow tube stem riser. Bench testing indicates the headlamp will keep going well down to 3.3-3.4V; this eliminates one step of power conversion while at the same time making a nice compact power pack that does fit inside the tube.

Currently just hacked together and wrapped in gaffer tape; if it performs sanely well in real-life testing, I'll print up a shell for it.

Stock Scematic and the stock PCB opened fine BUT.....

Renamed the PCB to try make a new one, generated new netlist etc and then a small footprint Error. No idea how you do this in KiCad to include it as I am a total newb. Can you export a component and add it to the Git?

EDIT Quick check in the footprint editor you can export footprints which should sort it  :-//

...So I clear off my desk/bench so I can get on my Windoze PC to read in here and grouse aboot the Mac kakking that video card again and Firefox (which just updated itself last night) crashes in the middle of this post.

Suddenly I'm back in familiar space, and all is right with the world again...  :-DD

And then the Trifecta... after messing around with the new handlebar setup over half an hour, and getting it all back together with even the grips intact and untorn... I realize that the reason I'm having such a hard time getting the brake levers situated so they feel right is that last night, before I pulled the plug on the project due to bleary eyes and aching back, I put the brake lever assemblies on the wrong sides and upside down. :palm:

To swap them around, I need to tear the whole thing apart again.   |O

mnem
Oh look... there's some more blood...

Not sure if you know, but an air compressor blow gun is very handy to float the grips off the handlebar with a cushion of air.  Makes it quick and easy with very low risk of damaging the grips.

Well, please do not do real-life testing on certain mechanical aspects.
I highly recommend changing that USB connection so it does not protrude as much.  Also, cover up the top of that riser tube.
I have plenty of experience with end-Os (going end over end) and you want to make sure none of that stuff is going to put a dent in your chest....
