> We're staring at a monitor for 8+ hours a day folks and there's no art or craft in staring at things, thinking or drawing diagrams. Yes, there's a whole invisible universe unfolding in the depths of the machine and the mental models can be incredibly complex and maybe one can even admit that there's a certain beauty to some designs or pieces of code. But programming remains very different form any kind of art known by man or the crafts which typically result in the creation of a physical object.

I think I get your point but I respectfully disagree. The same could be said of a writer staring at a piece of paper (or a computer screen) and good literature is uncontroversially considered art. I believe this is more a consequence of newer technology initially perceived as less valuable (photography vs painting, computer rendered vs manual processes, etc) in art, which seems a romantic view of how art should be created.
I'm not bashing ruby or something. I love ruby, I have been using ruby/rails since rails 0.9. Still using ruby with roda/sequel, and i think it is the best language to rapidly prototype and explore ideas.

But the reality is, that all the interesting and cool stuff is happening somewhere else now. Ruby is still a great language, but the active community outside rails is shrinking and the creativity isnt there anymore. People prefer to explore novel ideas in different languages now - rust, go, elixir etc, even if they do ruby for a living.

And rails is showing its age too. Every rails project i encountered was a petrified spagetti monolyth that had to be broken up and refactored into smaller pieces.

How to hold successful meetings (in academia)
pre-historic peoples would travel with their cattle -- their assets were the cattle themselves, not the houses. That doesn't mean they wandered around lost, you would have places you'd go to at different times of year, and may even set up some wells and more permanent structures around those places for you to stay in, but the cattle business was one of always being on the move.

Fun Fact: the word for "capital" derives from "cattle". Cattle was the first form of capital that was accumulated in the neolithic era. It would grow (bear interest), people would hoard it, so you had cattle-inequality, etc. This continued even into the bronze age

From Genesis 13

"So Abram went up from Egypt to the Negev, with his wife and everything he had, and Lot went with him. Abram had become very wealthy in livestock and in silver and gold.

From the Negev he went from place to place until he came to Bethel, to the place between Bethel and Ai where his tent had been earlier and where he had first built an altar. There Abram called on the name of the Lord.

Now Lot, who was moving about with Abram, also had flocks and herds and tents. But the land could not support them while they stayed together, for their possessions were so great that they were not able to stay together. And quarreling arose between Abram’s herders and Lot’s."

HSLuv is a sphere: https://www.hsluv.org/

They took the CIELUV/LCH/HCL solid and compressed it into a sphere, similar to HSL on top of RGB. The L* (perceptual luminance) value is consistent across hues, it can also replace the 100/200/300 scale for design systems.

But even the CIE model has flaws, chromacity is inherently linked with brightness/luminance, no color model can change that. A more saturated/chromatic color will always be perceived as more bright than a less chromatic one at the same luminance. And in order to create a palette you need normalization, which will always weed out individual color defining peaks.

The existing big players have all the customers. But the reason for that in this niche is the clients are hospitals, clinics etc., who are not always willing to search for better and affordable alternatives than what everyone around them is using.
Salaries work a little differently for pro athletes: they're not just earning money to live off now, but they also need to save up for when their career inevitably ends and they don't have any other skill to fall back on.

Seen in that light, $35,000 isn't much.
Oooh. Yeah, that makes sense.

I sadly don't know enough F# to even begin to think of something to make the tokens context safe.
Like SQL Server's row-level and page-level compression, you get more rows per page, so need to read less pages to process the query. From cold this means less disk or network IO loading the pages from storage into RAM, and it means you can fit more into RAM (and potentially CPU cache when spinning over small enough chunks of data) so you can do the same with less RAM or reduce IO so be faster with the same RAM allocation (as pages will not need to be evicted as often to make room for others).

The trade-off is a bit of CPU time, every time the page is referenced. Not just when it is updated or read from storage, but potentially every time it is accessed, even just reading, as the pages held in RAM are in the same format as on disk so the decompression needs to happen on read also (unless postgres keeps a cache of pre-decompressed pages to help with this but my gut suggests that would not be worth the complication - where it would help significantly you would just not use this technique anyway).

In a great many scenarios, I would say most, this trade-off is worth it because of the relative cost of IO and CPU time needed to save some of it.

It might be significantly detrimental to performance in situations where enough of your data fits into RAM anyway and you are performing CPU-heavy analysis upon it.

Side benefits include reducing the size of your backups and reducing the time needed to take them, so there are other potential infrastructure and administration savings to be had too.

These pseudo manager positions are so exhausting because one gets the job to do some things but not the full required authorities to carry it out. It is the cognitive dissonance that makes it so stressful and exhausting. Managers delegating without really delegating. I try my best to avoid doing them, asking enough questions, having enough demands beforehand to either make sure the scope matches the authorities or the requester walks away frustrated.

Just once, not every year. The cow have to be pregnant to start making the milk, but if you keep milking the cow, it will keep making the milk. The cow however does not have to have calf every year.
“Magic” in any language is always bad.

It makes for great demos but it basically means “this just works so you don’t need to know how it works”.

The problem is you always need to know how your tools work, often sooner rather than later, as you inevitably end up with edge cases and bugs in your application that simply can’t be resolved without that understanding.
As I think Naomi Wu said, the paper tests are extremely accurate in the lab, the majority of errors come from failure to read the output correctly (misinterpretation or otherwise).

So adding a digital readout that produces unambiguous results justifies the price.
The less memory unsafe languages get used the better, regardless of sandboxing.

Here C++ has an edge over C, because it offers the language features for memory safe array and string manipulation, and most C++ compilers do offer bounds checking support, enabled by default in debug mode, and selectively in release if one so wishes.

Ideally, Swift, Rust, Ada, .NET Native would have replaced all use cases, but we are far from that ideal, so 2nd best solution, C++ for the time being.

Note that Apple and Google also reduce to the minimum the usage of C, and equally advocate C++ instead, alongside their managed languages for their OSes.

So yeah, you get C11 in the box, pity that the OS APIs are a mix of C++ and their own languages.

The stack is regular 16 bit CPU-stack. Unlike most or all others, i was using the CPU stack for Lisp-nodes. The garbage collector made many errors when marking data from CPU stack. But it does not matter, with 16 bits you can have 65000 nodes, enough for all eternity.

Not much luck. That's a mobile game and probably cancelled since there hasn't been any news about it for more than a year.
Same. I have never even heard there is a relation to ruby, I always just thought it was just a functional language for the Erlang runtime. I had no idea the syntax was "Ruby like".
I wouldn't feed the troll. The many people who know and appreciate your language realise how much of an improvement Elixir represents over Erlang.

I use 1 email address for a lot of services, so that's the identifying key, e.g. online shops would upload their customer database to Facebook so they can target past customers with ads on FB. Actually, sadly using a different email wouldn't help me much because my name is quite unique, and of course the online shop would have my name for shipping.

Facebook's tool about third party data (not sure if that's the name) that they had to provide surprised me because it showed me which services actually did what I described above.
that's one way.

It's a tricky position as you want somebody with the right mix of tech knowledge, business knowledge and bullshiting ability.

Sadly, in my limited experience, there seems to be a large amount of people that excel at the latter but not so much at the other categories.
This is a really hard problem because news is inherently biased, political in nature and the incentives are on all sides huge.

EU Copyright Directive is requiring tech giants to license the right to reproduce copyrighted material on their own websites. It could make it impossible for Google to display brief snippets and photos from news stories in its search results without paying the news sites.

As a consumer, I find it difficult to form a clear opinion about it:

At one side, I don't want Google to become too powerful and can filter what reaches me as "news". It is also not fair that Google is earning disproportionate amount of money by facilitating search on the content of news agencies while they aren't getting anything.

At the other side, I want to easily find different sources for news with different perspectives and I don't want to be dependent to a couple of big news agencies like AP and Reuters.

I guess there is simply no black and white solution and that a balance needs to be struck with policy for distributing the power in a weighted way between the different actors.
What's behind the unequal threat of Covid
I gave up trying to reason about color models when I realized the CIE model wasn't determined rigorously and empirically. A full critique is beyond the scope of 3AM, but, it's kind of fascinating to go back to the roots of color models and read about how precisely they came up with them. Remember to turn on your skepticism when you do.

"X is a sphere" has to be reconciled with "What are the chances that our visual system would evolve into a perfect sphere with no flaws?"

For some reason, people are so determined to turn complicated phenomena into a pure and simple form. Even astronomy wanted to believe that orbits were circles, since circles are clearly more perfect. But nature isn't perfect; it simply exists.

It is a very smart turn of the Polish side to support the political crysis is Belarus. When the country is turned into chaos it will be beneficial for the Polish economy when many Belarussian workers go to Poland.

"IT haven takes authoritarian turn". Really? Isn't the so called IT haven exists under the exactly same government? What changed?

What changed is the situation of foreign instigated chaos intended to weaken a key Russian ally with the additional benefit that when many Belarussian workers leave the country they will serv someone's else economy. The competition of Belarussian IT industry will also be eliminated.

I really wouldn't advise to use CAS in 2020. It's an historical curiosity that stopped being relevant some years ago.

It's an old protocol to do single sign on within a company. It worked well and I've seen it used in large companies circa 2010, allowing to support sso in their internal web applications, for employees.

CAS is irrelevant now. The world has standardized on OpenID Connect (and SAML as second choice). Anything that's on CAS was migrated or is pending migration to OIDC.

As a developer you will have to deal with OIDC (and maybe SAML) for integrations with google auth, facebook auth, microsoft active directory. You really don't want to go for a dying ecosystem (CAS), that's a dead end for your career.

How can you demonstrate better that a product is in a healty and natural condition?
Most free range eggs are nothing more than branding just like fair trade coffee.

If it’s a large industrial farm free range or not the likelihood of the eggs being fertilized is pretty much zero, smaller farmstead/homestead farms that sell their eggs directly or to resellers can often have fertilized eggs tho.
That's the reality in every industry right now. The financial structures and power structures have interlocked. Companies will use inferior products because their business relationships are not based on merit but on personal connections between company directors.

Companies everywhere are using inferior products and inferior processes. It's obvious even in academia. Social networking is the only force which drives business nowadays. Social networks are not based on skills, they're based on kin selection. If you want to get business from psychopaths, you need to be a psychopath (or act like one).

Faking psychopathy worked for me. My bosses didn't like me for years when I was a nice guy trying to make things better, never promoted me then one day I blew up and quit the company in a really bad way which probably scared the crap out of them, then they ended up indirectly helping me with my next venture. Maybe they did it out of fear but it worked.

It's not about value creation, it's about being an asshole. Assholes respect assholes.
Our teachers tended to try that. Result - nobody read that except most disciplined individuals who skimmed the texts. I think the results with videos would be the same. The experiment was reproduced the same way in elementary school, high school and college. Readings are skipped unless you have to give the teacher something.

But most importantly, it is absurd to make this into a "system". The teachers can do mix of activities in school and homework can be mix of activities. There is zero reason to decide for one place for each activity, put name on it and then demand compliance.

Teachers help is necessary at times, then again students doing individual work and problem solving with no help is important in reasonable doses too.

I believe you can hit it with an HT, although the Youtube videos I've seen of doing it have been an HT with a hand-held Yagi cabled in in place of the usual whip antenna. A resonant dipole would probably pick it up - as others have said, the signal's fairly powerful.

This isn't a direct answer to your question, but here's some background as a starting point.

Some Asian cultures, especially Japan, have an inside-outside psychology. They present one face (image) to themself, family and close friends, and another to the office and strangers. It's like a mild form of multiple-personality disorder, but on an hourly basis:

https://en.wikipedia.org/wiki/Honne_and_tatemae

Also there can be extreme pressures within the family on what to study or do as a career, and resulting shame in not measuring up. One of my Japanese female friends had to run away from home to the US to study at art college, for example.

(To summarize, you cannot apply Western cultural norms to countries like Japan, which have no cultural similarities.)

For non-Japanese countries, religion can result in an inside-outside split personality also, especially with social media and surveillance culture today.

Most of my Muslim friends have private social media accounts for that reason, and even then are very selective about what to post for even friends and family to see, to avoid shaming drama. Doubly so in Islamic republics.
Their reaction to their main cities being napalmed down? Nukes, obviously...
Lots of condescending negativity in the comments here. Although a lot of it is true, it's not necessarily helpful.

I've been through this exact frustration, read everything there is on the topic, and have discovered things that work and things that don't.

First and foremost - DO NOT go hire anyone to do this for you. No one can. You MUST learn to sell your own products and services, there is no way around it. And no one can do it better than you.

Second, avoid paid advertising before you've learned how to generate high-ticket sales WITHOUT it.

Paid ads and sales people are for scaling only, once you've got your offer and your messaging down to a proven working system.

The good news is, you can get started easily and you can see results quickly, without spending a fortune on anyone or anything.

it then mixes syntax and data type issues. For example arguments are then vectors, probably to have [] as syntax. Though in Lisp one would keep argument lists: there is no technical need to make them vectors.

Talk as much as you can to your potential customers about their problems in your area of expertise & try to best align. Try to identify, understand and solve points-of-friction from these conversations.

Where to find potential customers? I'd try in following order:
- Talk to existing customers / contacts for referrals
- Talk to your past colleagues / friends for referrals
- Quality cold emails with decent research & pre-work
- Hang out on social wherever your potential customers hang-out and engage in meaningful conversations.

You may not strike success right away but do persist & keep identify what's working / not working. Follow-up regularly. If above gets tiring once-in-a-while - write content that can market your expertise.
