kebman··on Improved audio rendering with an optimised version of memcpy (2013)
At HiFi Klubbben in Lillehammer, Norway some guy tried to sell me gold cables, because the sound quality becomes so much better with them. I worked as an audio engineer at the time. I just smiled at him politely, then I left the store.

Next time I came around, he tried to sell me this CD player with a huge brick in it. "You get much better sound quality when the player has a brick in it," he told me. So I answered, "For sure! It makes the sound a lot more stable! Badum, tsch!"

Would that be a way to leverage fees in trades?
kebman··on Jailbreak Chat: A collection of ChatGPT jailbreaks
This is pretty tangential to the topic at hand, but I remember that innocent time, many years ago, when we went to the drug store and basically asked for all the ingredients you'd need to make a small bomb. When the teller heard the list, she frowned and asked, "So are you gonna make a bomb or what?" We grinned and said, "Of course!" Then she smiled and proceeded to hand us all the ingredients. We used it to make small squibs for a film project we had. Worked beautifully. Of course, had we done this today, we'd probably be sitting in some marathon questioning session at the closest police station.

I saw the Aurora in Oslo, Norway about a month ago. It's the first time in my life I saw it that far south. I grew up in Tromsø, where it was pretty common, but man... You never get "used" to really good Aurora. It's always amazing.
kebman··on Intentional Camera Movement Photography Magazine
How do you know their intent? Composition is largely a matter of cropping if you already have the basics down. On top of that, what is perceived as "good" is often very subjective, especially within art. Personally my main intent for using the effect was the vivid colours and the interesting streaks and shadows they make in the final image, and not really to cover anything up. The effect brings a certain life to the photo that a regular still just can't present, especially considering how straight flash photography too often comes off as really dull when you are forced to use only the hotshoe. But there is far more risk involved when using the effect, because when you move the camera, you often cannot be certain of the end result. Even more so with concert photos. They are made in an often very chaotic environment where you have little control, and where you more than likely are shoved around by the crowd as well. The slow flash really accentuates that, and you have to hope your movement syncs up with whatever is happening on the stage or around you while the shutter is open, which can be for quite a while depending on your settings. But then for that reason I think it's the most rock 'n' roll way of taking pictures. On the flipside the images does come out as very stylized, which no doubt isn't everyone's cup of tea.

kebman··on Intentional Camera Movement Photography Magazine
I've used various techniques for slow sync flash throughout my photography career. Worked exceptionally well for stage photography, night-time events, electronica concerts, and the like. Slow sync flash is when you let ambient light expose the film or sensor for a while, before you freeze the scene by activating the flash late. It really takes "painting with light" to a new level, though it's of course not the only way to use intentional camera movement.

Nearly all my photographs from such events use some kind of intentional camera movement together with a delayed or early flash sync. Slow sync flash is a delightful technique that you can be really, really creative with. Try it with double exposures, for instance, or with weirdly synced monoblocs.

I've seen great photos taken of dancers and animals in movement done that way. Moreover, this technique (if you've got it buried in your camera settings somewhere), sets you free to really disregard some of the holy tenets of photography, which is to never, ever move the camera, ever. Nay, in fact it prompts you to be dynamic and jittery, to lounge forward into the music, and let the final image really SHOW how great that moment really was.

No worries, I'll take a look at your site later. :) If it helps, I tried reaching the site from Norway. Thanks for reaching out! Edit: It works just fine now! Looks pretty interesting!
kebman··on WHO: No level of alcohol consumption is safe for our health
I don't agree. For one, I've done it myself, and you can have just as much fun, if not more without alcohol. Though when the crowd gets too pissed, I usually just move on or go home. I like to drink occasionally, though, but I often abstain because I don't like the day after effect. Second I know abstainers who regularly go out with peeps who drink, and they do just fine. It's ofc annoying the third time someone you clearly told that you don't drink still offers you a drink, but most drinkers are completely fine and respectful with it. So IMO it's wrong to force such labels on casual drinkers. Meanwhile I understand why there are labels on smokes, because it's hella addictive and it also seriously unhealthy even for third parties.

kebman··on What if AI didn't make you a bad writer, but a better thinker?
I wonder if this article is written also with AI help? For instance ChatGPT usually ends the last paragraph with "Ultimately". As a side note I've also seen sites use SEO by writing possible search terms into the article itself.
kebman··on Dinner for one: A little-known British comedy famous in Germany
A sequel would be an episode of what happened between Miss Sophie and the butler in bed after dinner.

A prequel would be the life and times of her now dead guests.

Don't get me wrong, a sequel would be cool too! Perhaps we could get a glimpse into Miss Sophie's legacy after she passes away, and how her butler needs to contend with her snarky relatives who wants to get rid of that infernal tiger on the floor, only to replace it with an even larger bear pelt.

I think this might actually be good. Always wondered what happened to her guests. Did she do them in her self? Did they trip on the lion while drunk? So many unanswered questions!

I'm probably gonna get downvoted for this, but a $5k vacation won't bring you lasting happiness. At best it's great in the moment, it'll bring you some fond memories, and perhaps it'll give you some bragging rights. And then that's it. It's nothing compared to achieving your dream. And you don't achieve your dream while on vacation.
kebman··on I am done. I give up
Survivor bias. Plus the mere act of "making it" is a great marketing tool on its own.

People love to hear success stories, and in turn they might spend money on hearing those stories in order to learn the secrets of the survivor as it were. This is why there are so many such stories, yet one may wonder how many simply live off selling stories like that, instead of actually reaping the rewards of their purported success...

IMHO if a guy can give out good advice for free, because he's already making enough on his success, then it's more authentic than a guy who sells his success stories. OTOH I get that successful people might be pressed for time, and that time taken away to tell the story might get in the way of following up on his actual success. In this way I guess success breeds success. And that's why you see a lot of people pushing their success stories due to survivor bias.

We're actually talking pedagogy here. The perspective of a survivor is quite different than a guy still struggling. So the question really being asked is, how can the survivor better explain to the struggler how to succeed? It's difficult to answer, and it may entail such things as silent knowledge, or details that are hard to convey. The path to success is different for people, and some do indeed have it far easier than others.

So how do you learn from that? Is the lessons from one-who-had-it-easy valuable? Well, sure, if those lessons lead to finding an easier route. But it could equally be a dead end. There is little to learn from one who was born with a silver spoon in his mouth, for instance, if your own spoon is made of lead.

On the flipside, there might not be as much to learn from someone who struggled a lot, because what if that person simply made a lot of mistakes? Perhaps he is cognizant of those mistakes; well, then you may learn from them. But if not, then perhaps it isn't as valuable. Though in general, when you reflect over mistakes—your own, or others—there is perhaps a lot to learn from that, as you'll at least learn what to avoid.

kebman··on Jami: Share, Message, Call freely and privately
I wonder how a service like this would look like over IPFS. Or if one could somehow merge the distributive power of IPFS with sharing of end-to-end encrypted information. Or perhaps there's already one? Or perhaps Jami is already superior?
kebman··on A fake job offer gone wrong
I let my guard down once, because of a third party survey from actually Apple. Then actually Apple allowed the third party to funnel me onto their third party site. And that's where I suddenly found myself subscribed to a $15 fun recurring weekly quiz. I trusted them, because it's Apple, right? Except it wasn't Apple anymore. And, well, it wasn't fun to me so I un-subbed pretty quickly, but the first $15 were already payed. When I looked into it, they'd hidden themselves through layers of proxies so it wasn't possible to find an office address. And there was ofc no help to get from Apple, because they assured that they were only responsible the third party survey, and not what happened when you where funnelled onwards. I still think this is pretty crappy customer service from Apple, and that cooperating with such a scammy company reflects very poorly on them. Oh, and I still want my $15 back! (Don't worry, it's nothing compare to what I lost on FTX...)

kebman··on Fantasy Jodorowsky Tron visualisations
Yes, you might be onto something.
kebman··on Fantasy Jodorowsky Tron visualisations
I have, and I think they're epic. That's why I think Jodorowsky has a big cult following that would have made it a financially sound idea to give him both money and creative freedom to make more movies.
kebman··on Fantasy Jodorowsky Tron visualisations
Why aren't film producers throwing money at Jodorowsky? The visuals and stories he'd tell would surely be mind blowing. (I ofc know these are AI generated images, but it still makes me wonder.) For instance I'm certain that it's his influence that made Nicolas Winding Refn make Neon Demon.
kebman··on What Happened at FTX?
This is true. For more on the topic, look up the seigniorage of the antiquity, and not least the ... self issued ... gold certificates of Stockholms Banco of 1661, boasting the first printing of bank notes used in Europe. It didn't go so well...
kebman··on What Happened at FTX?
In the end it would seem that SBF and his gang wasn't so interested in crypto as he was in fiat currency and real estate. As for the ramifications for the crypto scene, the trust of cryptocurrencies has gone right into the cellar now, if not in Bitcoin itself, then certainly in the centralized actors now purporting to offer it to retail customers. In turn, that would of course also warrant a rebate. Not least because it puts pressure on other bad actors on the scene.
kebman··on Is 40 hours a week too much?
I think people conflate "being productive" with "work."

The work is simply the contractual agreement between you and your employer. He or it has a notion about how long it's supposed to take, and you do too. And so on your end, you have to be willing to give up a certain amount of freedom in order to stay productive enough for the workplace to want to award you for the time spent in their service, whether that time is productive or not.

On their end, they of course want you to be as productive as possible, but they also know that it's not possible 100% of the time. And so that is the basis for the contract.

Then there are ways around it. Say you can make a hack that'll make you able to complete the job in half that time, or less. Lots of people get paid obscene amounts of money for very little "work" but the value of that work is simply that high, and so that's what they're paid for it.

So instead in thinking in terms of hours or work, I tend to want to think in terms of how much time I need to provide value. And the less time that is, the better - for both parties. They get better value for money, and I get more time to dream up better ways of creating value.
