Really, you just have to accept that a print made from a negative is a picture-of-a-picture. There is no inherently "right" way to convert a negative to a positive, any more than there is an inherently "right" color balance for a film to make the first capture with. The color balance and contrast levels you select are just an interpretation of the image, just like the initial exposure.

It's not too bad to get color balance right when scanning, as long as you didn't mess up the exposure too badly. Set the white and black points according to the histogram, adjust the gray point until the contrast looks right. Then, if there's color shifts in the highlights or shadows, play with the white/black points on one of the color channels until it looks right. Then pull it into Lightroom and do your final adjustments. It's intimidating at first but mechanically it's not that difficult, after you do a couple rolls you'll have the hang of it.

(background: film is basically three separate emulsions with their own color response curves, that happen to look normal when shot at box ISO. The farther you get away from box ISO, the more color shift you tend to get, eg clouds will start going yellow in an overexposed image)

Also worth noting that a flat scan is preferred to a high-contrast scan in most cases... you can always increase contrast in Lightroom but you can't pull back data that's clipped to zero or doesn't have sufficient bit-depth for good tonality. To phrase it more specifically, you want to try and allocate a good chunk of your bit depth to whatever tonal ranges are significant for a particular image, while trying not to clip anything to pure black or pure white.

Also, you should definitely give wet printing a try, it's a lot of fun for techie types who don't work with their hands for a living. You do pretty much have to be shooting B+W these days, not a whole lot of people still wet-printing color anymore, but as with everything B+W it's quite simple. With variable-contrast paper, you just make a couple exposures on test strips to find your highlight exposure and shadow exposure, then add these to produce a final print (split-filter printing/split-grade printing). You can then scan the finished print, if you like.

It's more of a fun thing than a technical necessity for 8x10 prints of 120 film, there is plenty of detail there for a 8x10 even on a basic flatbed scanner. But if you are doing 8x10s from 35mm film or larger prints from 120, then it's usually noticeably superior to do wet prints. If you are really going balls-to-the-wall on your hybrid digital workflow you can get a decent 8x10 or maybe 11x14 from a 35mm negative, but you'll need something like a Flextight or a drum scanner, which start getting pretty expensive to buy and run. Or, you send it out to a pro shop and pay $100 to have them scan it for you.
+up for Walden! great book (you mean H.D. Thoreau, I guess)
Indeed, I think of that book (which I read over a decade ago) every time I push or pull a door the wrong way. Reading it is like being able to see the matrix - but it’s simultaneously enlightening and frustrating when you realize how poorly so many things are designed.
I know it is a thing. My question is if there is actual money/progress being made there. Hence my comparing it to alchemy. A widespread practice that generally did not produce any results in what they were attempting.

This is standard practice in AI training. There are countless workers in Asia (typically) who are perfectly willing to help train your algo for less pay than Western workers, and the location where the work is performed doesn't matter at all.

What would be news is if Google were paying $11/hr + social security, etc. just to have people tell an algo which pictures have a dog in them. That would put them at a competitive disadvantage.
Is it built in to pg now? Last time I set up pg I had to add an extension to get UUID support.

Sadly, copypasting resulting URI as plaintext is most probably the only option for modern browsers, because any other way of top level frame navigation to dataURI document is blocked.

The primary form of escape reading provided for me was an escape from poverty. Books were my ladder, and my hope. Having few mentors to tell me of a 'world' outside of the one I was living, books were able to transport me to foreign lands, they helped me understand myself, others around me and the world a little better.

Through good books, I could have access to mentors who would would never know me, but I knew them through their writing, and I acquired the tools to add value to the world.

Yes there are many mass marketed B.S books, that's why I tend to read older books that are battle tested and still relevant today(Lindy effect).

Yes, some books have more impact or less depending on what period in our lives we read them, our personal motivations or what prior knowledge and the context that makes the book relevant to us.

Of the hundreds of millions of books in the world, we may only get to read maybe a thousand or so if we try. Someone could invest years of their life into something that takes 8 hours or so to read. I think there's a high chance that their experience reveals to us something which we wouldn't have imagined and amazes us about the world we share.
Unfortunately the way that comments are rendered depends on which view you use. There's probably a subset that works for both but many [new.]reddit.com users won't realize that their post doesn't render correctly for old.reddit.com.

Given this design, I suppose one must suffer: [new.]reddit.com adoption or the experience for old.reddit.com.
I would guess that with an app users are signed in and precisely identified 100% of the time, which allows for very reliable and deep user analytics.
To be fair, that's been tried a lot, and it keeps causing issues.

I'm at the point where I believe that you can't "layer on" or "abstract away" security like you can with other things, it needs to be thought about at every step.

Just look at attacks that can take advantage of content-length to pluck out which page the user is requesting of a mostly-static site, or how compression and encryption seem to almost be at odds with one another.

You can't ever just assume TLS will handle it when it's abstracted away, and while HTTP/3 may not get rid of those kinds of attacks entirely, bringing "security" closer to the application logic may enable better protections.

Choosing a house based on external appearance makes about as much sense to me as choosing a surgeon based on how handsome they are. Especially when that appearance ranking has nothing to do with cleanliness, or neatness, but, I don't know how to interpret this, culture or era of origin? Aesthetic, but not based on color or comfort or neatness or cleanness?

"Scarcity: Why Having Too Little Means So Much" - by Sendhil Mullainathan, Eldar Shafir.

Access to scarce resources induces a particular scarcity mindset, which the authors -- both behavioural economists at Harvard and MIT respectively -- show with a large variety of
well-chosen examples.

The kicker is that time is one of those resources. In other words, I may be economically well-off, but if I'm short of time, I adopt the same scarce mindset that poor people (poor in money terms). I fritter away my time, I don't save it and so on. This book really showed me to deal with my time as carefully as I deal with my money. Great read, of the Freakonomics kind.
There is very limited evidence that the bilateral stimulation has _any_ impact on treatment outcomes [0].

EMDR is PE with a marketing machine behind it. To quote Robert Ursano, a prominent figure in trauma research and treatment at the VA, “I concur with the view that what's new about EMDR is not helpful and what's helpful is not new,"[1].

There is a disturbing trend of EMDR being billed as a panacea by commercial training institutes without educating clients about equally or more efficacious treatments (PE, CPT) that are studied primarily in academic centres.

It's better to just not be on the computer consuming online content instead of switching websites.

I don't go on reddit and am here only occasionally (would be 100% gone if I could delete my account). Instead of replacing reddit/HN time with X.com, I just do other stuff entirely.

Is there something you'd rather be doing with your HN time?
I had that problem for a long time but eventually it stopped occurring. I assumed someone had fixed something.
>We spent too much time firefighting and not enough time innovating

I honestly don't mean this in a back-handed manner, but what innovations have come about since that time? Reddit is great because of its momentum and user generated content. That model does best when the admins stay out of the way for the most part. Many (including myself) are not at all a fan of the more recently emerging dark patterns or the site redesign. I don't see those as innovations.
I pruned my comments about a year prior, so anything useful should still be there.
They fixed that a few weeks ago.
That's disturbing! Why is that?
Absolutely. If you're friends, of course. Or maybe if you have enough money? But at that point, you might as well just go to the clinic.
Yes, it's incredible. Almost as many in Tokyo alone as in the entire USA.

You'll notice too that Japan (along with other Asian locations) received their first Michelin star in only 2008.

European restaurants have stars dating from the 1960s, so this is really just the beginning for the East.

When they finally get around to surveying Bangkok I've little doubt we'll see our first street-food Michelin star.
Many people can learn to program and companies that pay poorly will only be able to hire people who aren't very good and they will go out of business. Finding good teachers is very hard as well but the government will only pay terrible salaries and mostly hire poor teachers. The difference is when the teachers suck and students do poorly, the school doesn't go out of business, they just reduce the budget and it gets worse.

Version 4 UUIDs pretty much have to be generated from reasonable(-ish) CSRNG. The assumption that the resulting 122bits are universally unique requires that they are truly chosen at random, CS(P)RNG is the most sane way to accomplish that.
I got so sick of the "use our app" shit on every page that I installed a third-party reddit app (Apollo). They wouldn't be pushing the app so hard if it was actually to my benefit.
Yep. Look at woodworking, sailing, overlanding, etc. and you'll find people who care about their hobby and are knowledgeable.

Some popular subs can have good content, too - askreddit has a good topic once or twice a month, and depthhub (used to) have good curation of deep learning.
You could say the same thing about YouTube -- just look the "YouTube trending" page any time, it's a bunch of stuff only children and dumb people would be contributing statistics for (sorry to be pretentious, but am I wrong?). That doesn't mean YouTube isn't a valuable source of information -- you just have to find the right channels.

The Selfish Gene by Dawkins, back when he was more young and idealistic. It changed my relationships with people. Recently reading Sapiens I recognised the same qualities in the writing.
Interesting. Still, it's unclear to me why that exclusion is a valid way of doing the analysis.
Me too, but The Fountainhead struck me more.

Likewise. In addition, The Fountainhead was, IMO, better written... and it has the additional perk of being shorter than Atlas Shrugged. If anyone was thinking of sampling Rand, I'd almost always suggest starting with The Fountainhead.
Many internal bank audit processes ignore small discrepancies but eventually notice large ones. As apparently this did get noticed. Once you know a single withdrawal works, it's not a meaningless test try a large amount or longer time period.

I can't believe you wrote "Internet 2.0". Not sure why.
And even if you are generating v4 UUIDs, they are not necessarily cryptographically secure. So it might be possible, if lets say, a user gets a bunch of UUIDs that your system generated, it might be possible for they to figure out other UUIDs that the same system generated. Which is totally fine for what they were built for.
reddit ads aren't very profitable as most of the userbase is probably logged out or just goes to /r/all.

reddit also houses tons of NSFW and controversial content which probably scares some companies away, even if their ads won't show up there.

I don't understand how the pictures help. The core formula is compact, but that doesn't make it bad. A few sentences of explanation is great for people who haven't learned standard high-school-level math notation or who want a walkthrough as a refresher (so thanks tonthr author for writing it down ), but refusing to learn math notation is going to make learning every math concept harder, penny wise and pound foolish. I don't see how this blog post/book chapter's explanation is novel as it claims to be, or why every other explanation of floating point is supposedly poor. I suspect it's just a matter of learning concepts requires thinking, so thrilled author jotted notes while he was thinking, and misattributed his progress to the specific visuals and no to the process of thinking about the formula.

The hard part of floating point isn't the representation of numbers, it's how to perform arithmetic with rounding/truncation in the specified way (and why the specified way is preferred). The blog post doesn't touch on that at all.

Anecdata is also all that supports TMS and Ketamine. There's not been sufficient time for longitudinal studies to be conducted or more efficacious protocols to be developed.

Had your loved one tried ECT prior to ketamine infusion? Though its reputation has been sullied by popular culture, it is bar none the most efficacious treatment we have for treating severe and persistent depression, and its efficacy is well supported by decades of research and outcome tracking.
Lack of proper DCVS hinder the possibility of committers to publish early version of their work outside huge diff. Getting the code and submitting changes are a huge PITA.

It's not hard to find out why 90's cathedral style hierarchies hinder development process.

That being said, unless you are already a committer, it's gonna be very difficult to get your code blessed...
Though there hasn't been much research on it, I suspect that methoxetamine (MXE) might have the same anti-depressant effects as ketamine. Also, it doesn't have the urinary tract issues.

Also, it's much much cheaper on the black market than ketamine. We're talking around 1000 (recreational) doses for $20. Compared to say 10 (recreational) doses of ketamine for maybe $50?
I've also yet to find a subreddit I like. I admit I haven't tried recently, but the "high school" vibe is very much the one I get. I don't even mean in a bad way, I just mean in a very naïve way. I came of age on the internet, as a teen in the mid-90s, and I just feel like, 20+ years later, I've moved beyond the "everything is new" phase, and reddit still feels like everyone discovering things for the first time. Whether it's a car subreddit where nobody knows how cars work, or a tech-specific subreddit where nobody has the background of my peers.. I'm all for helping people along, but on every topic it feels like 95% rehashing the same old things I rehashed as a teenager.

I think it's just that, ultimately, younger people have more time for online community than middle-aged folks, and the average tone of most subreddits clearly shows this.

Perhaps I'd have a different perspective if I was pursuing a new hobby, so I was the n00b, but I'm.. not.
My contention is that median variability of cultural attributes between those cities is signifcantly less than median variability of cultural attributes in US cities.
I do mind them promoting their app, it’s a horrible app and they’ve continually ruined their website. The only way I can stand to use reddit anymore is through Narwhal, at least until they kill their 3rd party apps API.
>I'm very much concerned that rather than traditional psychotherapy

Why on earth would you be concerned about a tool which allows clinically depressed individuals to see immediate, significant improvement in their condition with relatively few side effects? You should also not group ketamine therapy with prozac, they are completely different drugs with completely different mechanisms of action, grouping them under a broad "antidepressant!" umbrella is borderline negligent.

Psychotherapy is often a long, drawn out process which doesn't necessarily always guarantee results. Not to mention the large amount of variance between individual therapists.

Psychotherapy is useful as an adjunct to psychiatric drugs, and vice versa. They are both useful tools when fighting mental illness, and are even more efficacious when combined. Drawing a line between the two for ideological reasons, instead of purely evidence-based results, is a mistake.
I take the same approach. Compared to something like amazon reviews the information tends to be more reliable.

I'm sure there are plenty of paid shills but my sense is that most people who post on reddit aren't trying to sell you something.
Neat, I had no idea. Michelin-star food for $2 is a steal!
> it really should be graded based on how much you improve over time rather than whether you can reach certain goal

Agreed. After my first year of regular P.E. I signed up for a class focused entirely on strength and fitness. No team sports. Two days on the track, three days in the weight room. Physically it was a far more demanding class, but it was taught by a far more reasonable teacher. Despite being among the slowest when it came to running the mile, I still received an A for showing effort and improvement.

We should probably be cautious about using the term "dark pattern" so liberally, otherwise anything on the web that we don't like could eventually be categorized as such and the term loses its power.
