thread_id··on The window trick of Las Vegas hotels
This is the scale that you need to wrap you mind around. The maps are deceiving. Stayed recently at Park MGM to attend conference at Aria. They share the same physical "Block" so it appears they are close. It still took 30 minutes of walking through connecting hallways and up and down escalators to traverse between the two hotels/casinos.

Sorry to break it to you Elon but you really did spend $44 billion on the next MySpace. There's nothing you can do about it now. All we ask is that you please stop trashing your Tesla brand. Oh!!! and by the way recommend to the BOD to make Tom Zhu CEO of Tesla. You can stay at Twitter.

All that innovation was introduced to the world with Apple and then later became standard on Microsoft PCs. It underscores the fact that Bill Gates innovated nothing but simply copied every body else and sold it to the corporate market.

In general, when travelling internationally, it is just easier to leave your phone at home and buy a cheap phone with a prepaid plan when you get to country. This avoids all of the potential intrusions that come with passing through security and borders.

Love the "Periodic Table of DevOps Tools"!!! Not only is it brilliant in its creativity - it is a very useful analysis of DevOps capabilities and where each platform provides functionality to support that capability. Nicely done.

What is interesting is that the technology that is most useful for providing verifiable online identity is blockchain. Yet the current applications of blockchain technology have become the greatest enabler of fruad and crime that modern civilization has ever known.

Very little of what we do as developers or software engineers is transactional. This is very creative work we do. So I don't take status about anything that they are doing. Rather I discuss all aspects of the problem they are trying to solve. Or ask questions about how they approach solving those those problems. I usually enter the conversation with the same verbal queue: "indulge me while think out loud about this....". We discuss concepts like technical debt or design patterns or junky data in our database and how to improve data quality. I also deliberately avoid creating artificial time boundaries. Everyone knows I prioritize quality and stability. (faster, better, cheaper - it's always better)

You have provided a wonderfully elegant description of the two ends of this spectrum. Spectrum is a perfect term to use becasue technical leaders who become managers exist on that spectrum in very dynamic ways. Everyone is surrounded by 360 degrees of team members who have different perspectives, expectations, needs, wants, etc. No one can be all things for all people at all times. For my own experience, depending on who you ask - my peers, my leaders, my reports, they will all have varying opinions of how I land on that spectrum and what it means to them. And if you ask this month and ask again next month their perspective may change both positively and negatively. You have to keep trying and growing and learning. You also have to be agile and flexible. Let go of the past and focus on the future. Assume best intentions about everyone. There is no perfect. Its all about the journey.

At 64 years I am still going strong. I consider myself blessed that I have landed a position that allows the to be the leader (I manage a small team) and still be hands on with everything: Architecture, desgin, coding, infrastructure, cloud engineering, DevOps engineer, DBA, the list goes on. It is a Goldilocks job. The technologies that we manage and master are miriad. We are a small company and my team owns the entire space. All my years of knowledge and experience enable me to be coach, mentor, and teacher. Over the course of my 44 year career I have played every instrument in the band. I manage with a socratic method which my team enjoys. Because I have been a life long learner, I have sought out and explored new technologies with eagerness and hunger. This enables me to lead the team to adopt some of these technologies in usefull and vaulable (to the enterprise) ways. The team absolutly enjoys learning and applying new and emerging technologies. I could not have asked for more from what will probably be the last gig of my career. I don't intend to retire until 70 (assuming I am that lucky - you'll know what I mean when you get here). I am having so much fun I wish had 30 more years ahead to enjoy what comes next. I always like to say: It's good work if you can get it - not everybody can.

Classic example of a hidden economic and social cost of a technology that is not born by the final end use of the products - in this case storage of electricity for many applications.

thread_id··on 2022–The Year the Hydrogen Economy Launched?
Here we go again. I refer back to this article from 2007 (which I just read again) and I am not sure that there is a compelling case for hydrogen....still. The subsidy forces the price equation but the energy cost of creating hydrogen does not change it's inherrent quality:

"The trouble is that making hydrogen requires more energy than the hydrogen so produced can provide. Hydrogen, therefore, is not a source of energy. It simply is a carrier of energy. And it is, as we shall see, an extremely poor one."

thread_id··on Applying a rule from Pixar with a camera from 1961
36 is the largest number of exposures available on a roll of film (in US the brands most commonly available were FUJI or Kodak). Normally 12, 24, or 36. So the split frame would allow you to take a maximum of 72 exposures. The format is still 35MM. (ok so this was based on memory)

But I did notice that the number 40 was red on the counter implying significance. I quick google search revealed the same question and answer plus additional manuafacturer: AGFA

https://www.photo.net/discuss/threads/20-exposure-35mm-film-...

"Got an offer to buy several hundred rolls of packaged Agfa APX 400 speed film. It is all in 20 exposure cassettes. Where have I been that I don't recall "20 exposure" rolls? Were they a special run for point-of- purchase at some kind of strange outfit like (insert schlock discount store here) or a serious product?...."

"They used to make 20 expsure rolls before they switched over to 24 per roll. That change happened in the 70s I believe, so the film is probably pretty old if it has got only 20 exposures per roll. While thats my best guess, you could be right, and it could have been special order."

The camera is from 1961 so would have reference to 20 exposure rolls.

thread_id··on Tell HN: I'm Afraid We're Shutting Down
Have you considered reorganizing as a not-for-profit and then seeking funding from foundations or combination of croud sourcing plus foundations.

You have a proven model and track record - clients that need support and businesses that are willing to participate. Well defined funding needs and a well defined road map for expanding your network nationally.

This way your idea gets to live on, you get to stay involved with your dream project, you get paid (and made whole as a creditor).

It occurs to me that part of this debate could be expressed in more modern terms as Declarative vs Imperitive programming.

In firstclass languages a complex problem can be solved by chaining together functions and can be written in a single statement (this depends on the implmentation of functions and types that are returned). Somtime 2 or three statements.

Versus using core language statements and packages to implement conditional logic, control structures, and operations. Relying less on packages that extend the launguage. Having full control over the implementation.

Personally I prefer declarative and wrapping it with verbose inline documentation.

One downside to this is maintaining the build environment. Packages are versioned and fucntions change overtime (deprecated in favor of new implmentations that replace the old function). Somtimes Declaritive implementations must be refactored to support newer version of packages.

Impertive implementations tend to be more durable and have fewer dependencies.

thread_id··on Mental illness, attention deficit disorder, and suffering
"...There are bigger downsides to ADD, like the weeks when I can't focus on work, or when I get distracted by some awesome new thing and don't do the things I should be doing, or how I lost interest in projects and don't always finish them, blah blah blah. I am not going to complain about any of that, it is just part of being me and I like who I am pretty well. Everyone has problems and mine are less severe than many. ..."

What he is describing is everyone. The last sentence should read "Everyone has these problems just like me."

We are conditioned from a very early age to compare our insides to everyone elses outsides - the personas that they represent - or more accurately that we represent for them. Whether we imagine ourselves better than that persona or inferior in some way - it is all illusion.

Nothing is good or bad but thinking makes it so (where have you heard that before?)

Reading the comments below I feel there is a lot of beating oneself up. I know... I do this all the time. When I recognize that I am doing this I redirect it to accept and love my natural self (very liberating). This is our human nature. We all share in this. We should feel perfectly natural and ok about our nature.

The difficulty is in adapting to the structure of society. We are challenged to find ways to adapt and manage our nature in order to find some measure of accomplishment in that structure. Some adapt readily. Others have to work at it. We all face the same challenge and we all acheive different measures of success. Just make sure that it is your measure of success that you are striving to achieve.

The labels and their definitions are all a product of a feckless mental health industry that needs to create something to justify their existence. The definitions describe observable human nature and the labels categorize them. The negative connotation is a judgement - this is what causes so much stress.

This body of work is dynamic and changing. The American Psychaitric Association Diagnostic Criteria at one time included homosexuality as a mental disease. Can't suffer from Aspergers because technically it is no longer a diagnosis. So consider these examples to help keep it all in perspective.

thread_id··on Ask HN: People who use different emails everywhere, who sold you to spammers?
SpamGourmet will be sutting down soon (circa 2019)

https://bbs.spamgourmet.com/viewtopic.php?f=5&t=1785&sid=3e7...

There are intersting tales of how users of this service used multiple accounts to thwart spam.

thread_id··on Ask HN: People who use different emails everywhere, who sold you to spammers?
I have multiple emails for most online accounts. None of them are generating unwanted emails. There are two accounts that I have had for a long time prior to this newer practice and these are constantly receiving unwanted spam. I was able to correlate this to a project I worked on 15 years ago when one of the other contractors on the project gave me a thumb drive to install software related to the project. It blue screened my laptop - but it was too late - my laptop was hacked. Ever since then those emails have been out in the wild. I learned my lesson about good thumb drive hygiene after that.

thread_id··on Ask HN: How do you deal with getting old and feeling lost?
> The problem is that by 35 you can't get by on novelty anymore because you've seen some version of everything there is to see.

This could not possibly be true. You have only just begun. The mere thimble full fo knowledge and experience that you have accumulated thus far is nothing compared to what lies ahead. But only you can make it happen. Make a decision. Take an action. The comments here are loaded with wonderful and practical advice. Louis Pasteur: "Chance favors the prepared mind".

Also consider this (this is a quote that I cannot give attribution for): "In youth we struggle with illusion of certainty. As we grow older we struggle with the certainty of illusion." We create the worlds that we live in. It is easier to follow a path that mimics and conforms to the structure of your environment. It is much more difficult to break away and define and follow your own journey. The feedback is not avaialble so you have to rely on your own internal compass. The choice is yours.

thread_id··on Delta CEO wants U.S. to put unruly passengers on 'no-fly' list
Under no circumstances should the Department of Homeland Insecurity should be co-opted into blacklisting U.S. Citizens on behalf private commercial corporations over disputes that it has with its customers. The CEO of Delta should be fired over such an abject failure in leadership.

And.... what keeps on getting lost is airlines like Delta and United would never find the space to get this bad if future customers would vote with their dollars and simply choose not to purchase their product. Then change would happen.

thread_id··on Texas scientists’ new Covid-19 vaccine is cheaper,easier to make and patent-free
Bottazzi said the reason she and her team did not patent the vaccine was because of her team’s shared philosophy of humanitarianism and to engage in collaboration with the wider scientific community.

“We want to do good in the world. This was the right thing to do and this is what we morally had to do. We didn’t even blink. We didn’t think, ‘how can we take advantage of this?’ You see now that if more like us would have been more attuned to how the world is so inequitable and how we could have helped from the beginning so many places around the world without thinking ‘what’s going to be in it for me?’, we could have basically not even seen these variants arise.”

thread_id··on Ask HN: Why does a busy man build a shed?
Compared to the abstract, conceptual, and ephemeral nature of engineering solutions from many diverse technologies that are forever transitory and evolving - Making things in the physical world from many different materials with their concrete physical properties that are governed by the laws of physics and require specific skills and tools and sequencing and order to be able to fashion them into a physical object that provides actual utility… Making things in the physical world can be quite cathartic and grounding. More like meditation.

thread_id··on AWS US-East-1 Outage: Postmortem and Lessons Learned
Jeremy Daly, 'Off-by-none' "For the other 99.99% of us building workloads in the cloud, a multi-hour outage may sting, and perhaps even result in significant revenue losses, but compared to the cost of implementing and maintaining solutions to mitigate these outages (that only happen every few years), it’s a drop in the bucket. I’ve got more important things to focus on."

This is an interesting perspective. All of our servers were up and running, our applications were accessible and running. We manage our DNS through an external provider. However, by design, our applications integrate tightly with multiple AWS services for various architectural components. The features that depend on those services were faililng intermitently throughout the event window.

As a remediation, we could replace all of those services with various platforms hosted on servers or provided by SaaS - therefore eliminating the dependency on AWS. Our cost model, support model, and speed of delivery would change significantly. This would obviate our reasons for adopting cloud based architecture in the first place.

Instead our approach is to examine how we have also tightly coupled our integration to us-east-1. And look for 'High Availability' design patterns that will loosely couple to a region with the ability to fail over to warn/hot region when needed.

Let me know how you are defining your response. I would like to consider additional points of view as we work through this problem.

thread_id··on How to develop black and white film at home with coffee (2019)

thread_id··on Xenobots: replicating living robots made from frog cells
"“This is profound,” says Levin. “These cells have the genome of a frog, but, freed from becoming tadpoles, they use their collective intelligence, a plasticity, to do something astounding.” In earlier experiments, the scientists were amazed that Xenobots could be designed to achieve simple tasks. Now they are stunned that these biological objects—a computer-designed collection of cells — will spontaneously replicate. “We have the full, unaltered frog genome,” says Levin, “but it gave no hint that these cells can work together on this new task,” of gathering and then compressing separated cells into working self-copies."

What could possibly go wrong here?
