I figured 300 megabit Fios would be enough but I think that when you cheap out, they more severely throttle places like Youtube on the backend.

I started with gigabit Fios when they first deployed in my area then ended up dropping to 300. As a single user, even if I'm saturating the link, I think I'm too used to being patient to accept waiting an extra few minutes or queueing up an overnight download for something massive.

Every online service I've used has been flawless, from streaming media to cloud gaming, and I'm in a fully wireless house with a single Ruckus AP covering it all.

I've seen over a thousand+ devices being covered by a 2Gbps pipe on a large network and not even saturate the link even during peak - and they were throttled to 150mbps per device.


Third party lenses that cannot be updated by the camera body will include a USB port.

Why would this be a good idea to break away from the norm of what has been done before? The mechanism of updating the lens through the camera exists. Why reinvent the wheel? It only increases the BOM for the lens to include the USB and the electronics involved.

Because third party lenses cannot leverage the camera body to update.

Sigma has a dock that allows updates to their lenses in this fashion however.


I suppose it depends on the system? I have updated Sigma, TAMRON, and XiaoYi lenses on my Panasonic and Olympus MFT bodies, as well as Panasonic and Olympus with each other: https://support.jp.omsystem.com/en/support/imsg/digicamera/d... (Sadly not an exhaustive list. I have firmware for several more lenses stashed away in my archive, but the upgrade mechanism is the same.)

I shoot the m43 system (have since the GH2, then E-M5, E-M1, and now a G9 II) and didn't realize this.

I only have one lens tight now (I tend to stay small on my system but this is a low point) but I'll keep it in mind.

Thanks for the info!


You can update sigma lenses through Sony camera bodies but it requires running a program on your desktop with the camera plugged in and it’s a bit of a pain. Especially on macOS where it requires enabling kernel extensions.

Would have been nice if Sony just let you drop a file on the sd card to load an update.


Didn't realize this, thanks!

Only for their old "Art" lenses, the modern "Contemporary" lenses can leverage the camera body update mechanism and only need a file on the SD card containing the firmware update.

"Contemporary" lenses aren’t more modern that "Art". The monikers were introduced at the same time, along with "Sports". Rather, "Art" is Sigma’s high-end line, similar to Canon’s "L". "Contemporary" on the other hand is a somewhat euphemistic term for "consumer" or "affordable".

Ok, that makes actually sense.

The author says PH screwdrivers may be used on JIS screws, but in my experience they strip every single time.

This is incredible work, though.


JIS screwdrivers are 100% necessary. It may seem PH fit at first, but it's _a tiny bit off_ enough to cause damage. The point of JIS is shorter and squared.

Thanks for the kind words! The ifixit screwdrivers I linked are JIS compatible.

The PH-0 and smaller screwdrivers from Good suppliers like iFixit or Wera are actually JIS because there's no downside.

But if you happen upon a real PH-0 it will destroy the JIS screws.


I made myself a pixel font for composite (well, monochrome) video output on an RP2040:

https://github.com/PhobGCC/PhobGCC-SW/blob/main/PhobGCC/rp20...

(search for 1 to see letterforms)

The letters are 8x15 and verticals are 2 pixels wide to work better on older CRT televisions with less-sophisticated chroma filtering on their composite inputs.

I explicitly tried to avoid locking into 45 degree diagonals...

My only question now is, how do I turn this font into something I can use on a computer? I couldn't figure it out the last time I tried.


A few different resources with various ways to go about it, one of which may be near what you were hoping for:

Calligraphr: https://www.calligraphr.com/en/

PixelForge: https://www.pixel-forge.com/


I made PixelForge [0] a while ago just for creating pixel fonts and being able to export to TTF. I had it semi-abandoned for a few years, but I'm about to release a new version in the next few days! [1]

Quite impressive [1]. Did you base it on a specific font, or did you just draw it however you felt like?

I did it with no reference to other fonts, just to my own tastes. It took a bit of iteration to get letter centering on the lower cases to work well but I think it's in a good place.

You can see an older version ("a" has been revised to better center the letter) in action on a monochrome CRT here: https://github.com/PhobGCC/PhobGCC-doc/blob/main/For_Users/P...


It's an organization that is effective as an opposition party of sorts.

Simplex methods can handle those tough situations, though.


Simplex is not applicable. Simplex only minimises a linear function (f(x)=c'x) under linear inequality constraints (Ax≤b). The minimisation problem here is unconstrained, but (very) non-linear.


I guess I wasn't being precise, I meant Nelder-Mead.

Or coöp if you want to be fancy.


It's generally inconsistent. The first sentence is written, "A co-op is an economic system built on the simple idea that coordinating the economic activity..."

Co-op is correct here, but not in the title (Coop). Probably personal taste, but I'd also like to see hyphentation for "co-ordinating", "co-operate" and "co-ordinator" as well.

Then I noticed the em-dashes, so perhaps I'm reading the machine's work anyway.


If you can put something in it it doesn't count as crumple zone and the car has to be engineered with a separate crumple zone anyway.


Collapsing trunks have been a thing since the 90s.

There's no regulatory requirement for crumple zones. There's regulatory requirements for performance. The cheapest/easiest way to meet these is crumple zones.

Your luggage and golf clubs aren't gonna do squat in a collision. The regulators don't care that about the one in a million chance that someone gets into an accident a) where crumple zones matter b) while hauling objects so solid they don't just round to "no effect" because they have bigger fish to fry and if you create a "standard loading" for the test the OEMs will simply design to that and basically create a bunch of work and expense for marginal benefit.


Yeah, but not many people have the habit of hauling solid I-beams of steel in their "frunks".

I don't really believe the average groceries load will add that much rigidity to this space as deny its function as a crumple zone.


What has changed is that the US's failure in Iran has directly impacted many of its former allies all at once, and the current administration clearly shows that it doesn't care about them at all.

This lack of consideration will lead to significantly less favorable trading for all of the businesses you listed, regardless of their current prowess.


Replace Iran with Iraq and this was all true 25 years ago. And that was an actual failure.

Fundamentally nothing has changed about the world or the relationship between the US and its allies. Once Trump is replaced by someone closer to European social values and less of an asshole the temperature will change. Just like it did from Bush to Obama.


Can you really look yourself in the mirror and say with a straight face that fundamentally nothing has changed about the relationship between the US and its allies? Do you really think Europeans will be quick to forgive the wrongs of this administration? They’ve lost faith in our political system and will, rightfully so, do everything in their power to disentangle with us. The problem with your theory is that they know even if Trump is replaced by someone closer to European social values, our electorate could just as easily completely reverse course in 4 years. It literally already happened. Bush never threatened to annex European territory with military force as far as I can tell. But I understand why in these chaotic times you’d want to gravitate towards hopeful fictions.


Yes. Nothing fundamentally has changed about the US/Europe relationship for 80 years. Trump being a royal prick doesn't mean his message is fundamentally different than what any other president would send. If the US elects Kamala, for example, things quiet down and go back to normal almost immediately.


If you buy a ChaDeMo Leaf you do so knowing that it will likely never go more than a hundred miles from home.
