> 2,500x magnification

You can, of course, magnify as much as you want; but you won't see more detail.

"Junior" microscopes often brag of a 1000x magnification; but that only works if the lenses are really good, and in that kind of microscope, they aren't.

You need 1000x to see bacteria. Bacteria are really boring to look at; they appear as undifferentiated spheres or rods. And even then you can't see them at all without fixing and staining.

Single-lens microscopes suffer from spherical abberation (only the centre of the image is in focus) and chromatic abberation (everything has rainbow fringes around it). These problems are worse with greater magnification.

As far as I can tell, the best "mass-market" compound lenses these days are made in China.

Source: I bought my son a microscope a few months ago; he said he wanted to see bacteria. I hoped a "junior" 'scope would get me off the hook, but I consulted suppliers, and they warned me off, and told me quite a lot about how to choose a 'scope. I also bought him a set of stains and solvents, including a gram-staining kit. I did a fair bit of research before I spent money.

The old man needs health and life. Without health, life would just be a tortured existence and at some point "enough is enough".*

Those businesses have some shared infrastructure and brand--maybe more than WeWork--but they're still largely city-by-city labor-intensive retail businesses that still can't clearly profitably operate at scale, at least at their current cost structure.
Dating "strategy" sounds so distasteful, to put it nicely. Just be honest and try to connect with the other human.
And even in the "comforting" movie version, it's still different in real life where they start gasping for breath. I at least thought the person was in pain or suffering somehow. (I did ask the Dr. that came to give us the death certificate and apparently it's because either the brain has shut down or and the body is still trying to perform it's duty or vice-versa and there's no pain or suffering just a part of passing away).
Yes, many (if not most?) providers stopped taking insurance for various reasons. The rates provided by insurers are a fraction of the rates they can get charging out of pocket. And insurers try to shorten therapy sessions, or ask why a patient still needs therapy, etc.

I'm in digital physical design and part of that 99% of the army. The schedule is king. If we make a mistake it is another $30 million for mask costs and 4 months in the fab to get a new chip to test. Contrast with software where you can change 1 line of code and recompile and test in seconds. We do so much to minimize risk by reusing existing blocks, licensing third party IP that has already been validated in silicon, and armies of verification engineers.
*Everything* is covered in lanolin when you're shearing.

I used to wear my scruffiest most ripped zip burst no buttons tied around my waist with string jeans while shearing (in particular while bringing sheep out from the pens to be shorn). I'd wear them for the whole week we were shearing, and then just burn them. There's no way you're rehabilitating anything you wore that week into an item of clothing you can wear in public.
The Buddhist point of view on this is closer to “the default state of life is unsatisfactoriness”. The word “suffering” tends to elicit thoughts about pain and distracts from the myriad of other ways humans “suffer” daily.

> life is no more synonymous with suffering than it is with peace and joy

I’d argue that by default, life is closer to “unsatisfactoriness” than peace and joy, due largely to the evolutionary drives that make us strive for more. While you may be fortunate enough to experience the latter, it comes only through deliberate effort and a successful navigation of life’s basic survival requirements. Living in a modern society shields most people from the more persistent existential suffering of our ancestors.

Hunger, thirst and bodily breakdown are guaranteed. Peace and joy are optional, but what make life worth living. But it is seeing “suffering” for what it is - a mental state that we have the power to change - that makes living a peaceful and joyous life possible.
My replies weren't entirely serious. The parent paraphrased Jurassic park so I think I'm allowed to reference other scifi tropes.

I don't think that's the 'best' case. Dinosaurs evolved from simpler things than tardigrades so if we mess up this planet enough that we have to leave and only the tardigrades survive, our offspring could return to find giant tardigrade type things that eat our not so human children. Or we could time travel forward to that time. The choice of delorean, TARDIS or some kind of planet of the apes time travel, I leave up to you.
In my view FAANG jobs are beside the point. I've puzzled about this a lot, because I'm technically a "hardware person" with a degree in physics yet I'm also a good programmer. Many of my physics classmates became programmers. I could hypothetically bring myself up to speed on the latest software development practices and make myself employable at it. Maybe not at FAANG, but probably somewhere decent. But I've never made that jump.

I work in an office that has a sizable software development department, so I'm quite familiar with what they do, and what their work environment is like. It's not some distant mysterious place. They're my lunch buddies.

There are also lots of people who are quite bright, and do difficult mental work at lower pay, yet don't learn to program for whatever reason. Those of us who program know that it's actually quite easy, yet is an impenetrable barrier for most people, and we just don't know why.

There will always be somebody who makes more than you do, but it doesn't explain why people aren't all leaving their jobs for higher paying ones. Part of it may be psychological inertia -- I might be guilty of that myself. But I think another part is that we don't actually know the recipe for success.
> For comparison, double entry accounting was surely not invented through boredom.

The man that invented it had time to spend writing books and not slaving away at work.

Your "for comparison" is same "a well off man did what they liked" as the thing you're comparing to.
> but if someone has more confidence in their skills than they should, typically that leads them to try things that they otherwise may not have attempted?

Not always. They can also be blinded by the current state of things instead of thinking of new solutions or challenging the status quo. People can be over confident in their code and refuse to write tests or their assumptions based on old knowledge and go down the wrong path...
> It's also - in terms of performance - super fast

Kysely is also super fast. Your bottleneck will always be database requests. If you're chasing every milli, why node.js?

> the extra database drivers being core and developed as part of the main project.

Kysely's dialects are dead simple to implement on your own. As evident by all the 3rd party dialects being open-sourced and all the comments from people using Kysely in production with stuff like cockroachdb, mariadb, clickhouse and such.

Its unhealthy to maintain niche database knowledge in the core. We just don't have the time (FYI we do this for fun, not trying to catch all the sponsors and get VC funded) to play around with all of these technologies, and stay up-to-date with changes.

Both Sami and I have submitted pull requests in 3rd party dialect repositories in the past. I maintain a few dialects on my own.

> It supports prepared statements, which is awesome.

In connection pooling scenarios Kysely was mainly built for, prepared statements are arguably "not that great". In FaaS, a burst of requests might make your database work extra hard, as each new lambda instance comes with brand new connection/s.

> I prefer the way that it lets us write parts of queries, and compose them - like you import expressions like "and" and "eq" and you can write and(eq(users.id, 'x'), eq(users.name, 'Tom')) and you can actually stringify that to the SQL it generates. Or you can do a custom bit of SQL and use the names of table columns in that, like `COUNT(${users.name})`. I can't say scientifically that this is superior, and it's almost a little weird, but I've really found it a nice way to compose and debug queries.

This has been part of Kysely for a while now, and is only getting stronger with new `ExpressionBuilder` capabilities. The fun part is, you don't have to import anything, and are not coupled to your migration code.
I think to portray it otherwise would be to lose the message, and the fact that Wallace commited suicide should give credibility that the thoughts he wrote beforehand were those of an eventually suicidal man.

In my opinion, without the immutability of the situation the metaphor loses its meaning. People don't kill themselves because they feel they're in a situation they can get out of. I think it does more harm for those with suicidal ideation to ignore their feelings rather than validate them.
Software salaries in both places are also a lot lower.

No, you suggested that leaving insert mode to navigate by words is somehow less efficient (since navigating by word is your primary way to navigate in lines) and that maybe that's why you're happy you stopped using vi.

Now we found out that leaving insert mode to navigate by words requires the "same number of keys", so @gsinclair was right and it is unnecessary to stay in insert mode for navigation.

> Same number of keys, but works pretty much everywhere. The box used to enter this comment, for example.

If efficient word navigation was the only thing vim key bindings had to offer I wouldn't be using them. But they do offer many things the current text box does not offer and since (as a programmer) I'm spending 95% of my time in an IDE and not some browser text box, I'll gladly accept some inconsistencies if that means editing and navigating in my IDE becomes more pleasant.
Because the vast majority of them eventually (often pretty soon) change their mind about it.
For me, a couple things stand out, mcdonalds like consistency. I've been to wework in several countries and each time it's quick to get setup and on with your day. Generally, they're run in a consistent manner with an overarching corporate, which takes some of the interesting local customs out of doing business. Think about renting an office for a month in a 3rd world country.

They're community spaces also, group get togethers of similar minded people abroad. The spaces are generally pretty good too. I've been to a bunch of events at my 'local' foreign wework.

They're expensive, but when you're working sometimes that doesn't matter so much or is paid for by your company.

Like Uber, they're not perfect but they enable a cool way to live for me.

I'm a 25 year professional in the industry so I've never really thought of the hobbyist side. I use software from commercial Cadence and Synopsys that has a list price of over $1 million for a single physical design tool license and we use about 200 of those licenses simultaneously to tape out a chip. Then we spend about $30 million in mask costs. If we make a mistake it is another $20-30 million for new masks and another 4 months in the fab for a new chip.

Google / SkyWater / eFabless have this program for 90/130nm chips. That is really old technology from the 2002-2006 time range but it is still useful for a lot of types of chips.

I'm sure co-working is still going on but I work at a fairly remote company and I don't know the last time I've been on a call with someone in a co-working space.
