And I've taken the bike off 6ft drops and ridden it decently hard most of it's restored life.

CF repair can be done and plenty strong, it's just more risky because the properties aren't isotropic and simple like steel/alu so you can't just weld in a piece of metal of roughly the same thickness. I would not want to repair a bike I don't ride myself.

Your 35mm f/1.4 lens has a physical aperture of 35mm/1.4 = 25mm, so the equivalent 70mm lens with a 25mm aperture would have an F-stop of f/2.8. Hmm, can't think of many modern 70mm lenses besides Sigma's 70mm/2.8 macro which should have the same DoF, or if it's a standard zoom they should have equivalent DoF as well (unless it's Canon's f/2 zoom).

The (acceptable) depth-of-field is derived from blur-disk diameter, and the circle-of-confusion, for an object at a certain distance from subject ("point of focus") and relies only on physical aperture and distance to subject as stated (or alternatively, f-stop _and_ focal-length, because "phys. aperture = focal-length / f-stop").

I still have a 13-year old 24" iMac from 2008 that is working fine and used to let kids watch some Netflix, I only jsut retired it because streaming sites dropped support for the OS and browsers.

I have a 2010 Macbook Air on its original (but limping) battery that I used to use for serial comms and electronics stuff, still working fine. Besides the failing GPU, my old 2009 and 2011 iMacs run well (and some amazing folks figured out how to replace the MXM which I did, baking also worked).

My Samsung, even Microsoft Surface Pros, were pretty creaky and sloppy after about 3 years.

There are a couple threads on DPR, I found this real quick: https://www.dpreview.com/forums/post/59542514

I don't know what they're currently printing weekly, but afair they print a billion or so every couple weeks when they're really at it, that's probably enough to substantially move the market, or at least support it.

What happens when there's no more $1B over a few weeks to support BTC when the price is under pressure next time?

I'm not saying that's necessarily the case but the problem with tether and how it's used is potentially much bigger than the market cap indicates.

Why is the opposite of "bad government" always "no government" and not sometimes just "better government"?

It sounds like they are creating large quantities of the "offending" protein via the vaccine mNRA mechanism in normal cells. Normally the antibodies/T-cells would attack the myelin coating of nerves and the brain but with the protein being abundantly available anywhere the immune cells are "kept occupied" and leave nerves and brain alone.

If this treatment works as I understand, you would need continuous refreshers each time the mRNA injection is depleted.

If Carlsen is a fake, so is every chess player he has ever played, the whole system? Epidemiologists lied about masks (or they really didn't know better 3-5 months into the pandemic, also not good), discount everything else said? I've heard these arguments often lately :/

Experts not being "real" implies that there's no absolute expertise whatsoever and implicitly legitimizes dismissing any argument whatsoever on a single failure and allows people to believe that any opinion (including their own) is just as valid. I think this is in part to blame for our "post-fact/post-truth" phenomenon. Many people decide experts or government were wrong/have lied before and can no longer be trusted. And when an outsider comes along with contrarian but convenient ideas, why not believe them, nobody else is to be trusted after all and every opinion is valid.

Any expert opinion can be wrong but the prior is that an expert opinion is much more likely to be correct than your own, or a politician's, or a blogger's.

NB: I want to note that the author's point is much more nuanced and (more importantly!) narrow, but it's not evident from the title or a superficial reading.

Maybe there's some accounting subtlety I am missing here (or is "gross margin" != "gross profit margin"?).

Looks like a ZWO ASI294 MC could be interesting. It's "only" Micro 4/3 and $700 in the cheapest config but having USB-3 and drivers may be what I was looking for.

Full-frame astro cameras are unfortunately around $5k+ (albeit with a resolution similar to a $3.5k A7RIV).

The EU has really been quite a convenient scapegoat, not just in the UK. I wonder if politicians on all sides will/can continue to blame the EU now that the UK has "full control". I have a feeling that, yes, they will.

As much as I consider myself a pan-European, the European institutions, governance and government unfortunately make for a (mostly deservedly) great political target.

The whole likelihood basically hinges on the fact that the outbreak occurred in Wuhan and that the Wuhan Institute of Virology has been working for decades on enhancing coronavirus strains. That's quite strongly circumstantial but it's not evidence. Possible chimerization and furin-cleavage insertion seem a lot more interesting imo but are weighted much lower.

Based on their report [1], most of the likelihood of lab-escape (almost 50x weight) just stems from the fact that the outbreak is in Wuhan. They state that it's because of the proximity to Wuhan Institute of Virology (WIV) and the lab's gain-of-function research - only one of 5 locations world-wide.

That single "bullet-point" re-weights zoonotic origin from 97% to 56% and lab-escape from 1.4% to 42%. Otherwise their final likelihoods would be: "zoonotic" 85.5%, "lab-escape" 8.5%, "bioweapon" 6%.

His photos from Rwanda with the iPhone 7 just looked so much more natural and "real" [1].

If I were spending that money on a fixed-lens camera, it'd be a Leica Q (thanks, craigmod :/ ) but the concept is interesting.

So of course RAW doesn't make for better photos, but for original input data to do your own edit on. If you don't know how to edit, you're probably better off with the experience/work that the manufacturer put into the in-camera presets.

In my opinion the main advantage is that RAW files save the full color-depth info _and_ RAW files are not gamma-mapped (i.e. linear encoded), that enables all of your use-cases above. You would still get 90% of that advantage if you were to demosaic, color correct to a profile-connection-space but keep the linear encoding and original 12-16 bit depth, even if you were to compress that data via DCT/JPEG to save space. That's sort of what ProRAW is.

That said, Olympus does a couple computational photography approaches (handheld multishot high res) and Fuji recently introduced in-camera HDR - but I tried neither.

RAW files just give you more latitude after the fact, and editing can either really eek out the last 20% or allow the photographer to better express their "artistic vision" and achieve a look (eg split toning or color grading). All this worked before on jpegs even, but raw just closes the camera/smartphone gap a tad bit more - especially when it's easily available to everyone.

You might be right that it's currently a niche, but if the UX improves, widespread adoption might happen.

I bet if you showed 20 non-photographers 2 images a phone screen, one from the phone and one fullframe edited, most wouldn't appreciate the difference.

That said, I wouldn't give up my camera for many shots but I can understand why many people do. Post-processing camera raws is definitely more cumbersome than quickly editing photos on a phone.

OTOH, those robust lenses from the 50s to early 80s survived until today and are often still used and adapted on modern mirrorless cameras.

Just want to point out that, if I'm not mistaken, at that point only heating was covered by welfare but not electricity. In case anyone assumed it should have been covered by welfare and ppl somehow still got cut off.

The point was that high energy prices do not necessarily mean that more people are without power or that the poor are necessarily worse off - like everything it's a broader societal issue.

Btw, I do agree on the disadvantage for energy intensive industries. Industry power prices there are ~3x US prices afaict.

I didn't have time to read the paper, but reading the abstract I don't see a claim that the gradient descent model approximated by a kernel machine is equivalent to an optimal fit obtained by SVM maximum margin hyperplane fitting.

I assume one likely ends up with different hyperplane fits from converting a NN/gradient-desc-learned model to kernel machine vs learning a kernel machine directly via SVM learning.

I don't think the US collects national stats but it sounds like Germany is pretty average in terms of "energy cost burden" amongst European countries. [1]

I found stats for CA AND TX, 700k/40M disconnected in CA in 2016 and 900k/30M in Texas vs Germany 330k/81M - for whatever it's worth, didn't check methodologies. [2]

So going 100% renewable or nuclear for electricity production wouldnt' even make more than 15% difference.

I wonder what causes all that additional energy consumption from fossil fuel sources then? I always blindly assumed ~50% of our energy consumption is in the form of electricity. Cars and transportation, heating are obvious but I wouldn't expect that to account for such a large share. Does industry use so much fossil fuel for energy?

If we look at electricity shares, then Germany did better albeit still at an undeniably high cost.

And second, as has been discussed in another article shared on HN - Germany bank-rolled a lot of the solar "virtuous cycle" and China's solar industry. Now any following country can just follow suit and achieve the same carbon goals much cheaper, even if they 100% follow what Germans did, because the technology is more familiar and manufacturing is more efficient. Kind of a "first-mover disadvantage". Though I think many Germans are ok with financing many of the advances in renewables.

Edit: I forgot to add, this time period also coincides with Germany's prompt/hasty nuclear exit after Fukushima which was expensive but quite popular.

The two very last graphs on energy production mix show that the US mostly increased natural gas for coal and Germany renewables for nuclear, and then the last few years finally renewables for coal.

There seems to be an acceleration of renewables adoption in the last 3 years and Germany decreed to exit coal-based energy production by 2038 afaik.
