I bought a Herman Miller Aeron off eBay a few years ago while I was working remote. Until then I'd been experiencing pretty regular circulation and back issues (and I'm a relatively healthy person under 35). Now I have no pain and no circulation problems.

I ended up taking the Aeron to work when I took another office job, and bought a second-hand Steelcase Leap V2 for home. I like them both for different reasons. The Aeron is more comfortable over long sessions (which is why it is still at the office), but the Leap is still plenty comfortable and, to me, is more adjustable.

My only complaint about the Aeron is the front lip prevents me from _ever_ folding one of my legs under the other (sitting on my ankle, basically). The lip makes that particular position painful (and probably I should not be sitting that way, but not being able to is a bit limiting).

EDIT: Also seriously, go find a dealer near you and try some out. You'll know pretty quickly whether you want to spend 8 hours in the chair or not.
> I don’t think I’ve ever written one correctly on first try.

Please don't take offense, but this is odd to me. I honestly severely doubt I am some sort of programming super genius, but I have never had any issues setting looping logic correctly. (I took four years to teach myself programming & CS and now I've been at my first professional dev job for ~6 months.) None of my colleagues seem to have such issues either. What are you experiencing trouble with most? Off-by-one?

Well we have such quandaries with yaw dampeners too. But yaw dampeners are not computer controlled. I think it's a substantial betrayal of FAR 25 if computers are being allowed to paper over aerodynamic defects or non-compliance with applicable FARs.

Using computers to aid safety, to reduce pilot workload, that's all fine. But to use them to certify an airplane as having certain aerodynamic behaviors when they do not really have those behaviors? Perverse.

And further, the software routine under discussion can in effect be neutralized, easily, in-flight, by flipping two switches. Is it really acceptable, by Boeing and the FAA, to render an airplane legally unairworthy by flipping two switches? And even more damning, to me as a pilot, is they apparently found it acceptable to require no training for the true behavior of the airplane minus this augmentation that is easy to disable inflight and is in fact recommended to be disabled as a memory checklist item for certain kinds of emergencies?

Seriously what the fuck?

If true it is wrongdoing. It's wrong for Boeing to go down that road, it's wrong for the FAA to permit it - until the FARs are changed. There should be public hearings and all kinds of regulatory requirements for expected computer and software standards, failure rates, redundancies, and other guarantees. We have such guarantees in writing for the physical aerodynamics of the airplane! There absolutely should be equivalents for computers and software if they are somehow going to take up the slack for otherwise inadequate aircraft design. You don't just get to silently wordsmith everything and say oh this computer thingy here will satisfy the aerodynamic requirement.

Fucking hell. It makes me angry. And that's why I really hope there is a misunderstanding, that really the airplane is certifiable as airworthy without any computer augmentation, and that the problem is merely that the pilots were kept out of the loop to avoid type rating required difference training. That's bad enough. But I think it's worse to paper over aerodynamic short-comings, waiving it off with computer augmentation when not a single allowance for that is made in the FARs.

Happened the same to me. I felt really overwhelmed. The only solution I have is doing less. Furthermore I pick things which do require no/low maintainence/time/energy. Now I feel much more satisfied.

The real question to me is how and when to say no. Accepting I won't have the time for everything and chosing certain activities which makes my future freedom broad.

My priorities are: health(physical activity & food), connections: close family + a few close friends - and dedicated "random" time to feel more freedom and have some opportunity + work(+personal project)

Many areas have office liquidator types of places where you can get almost new Steelcase Leaps for $200-400. I got one for $250, it retired my Aeron, I find it to be much much better.

I use SQLite, although like you I also do not have huge databases with a huge number of accesses. I run a NNTP server with SQLite for the data storage. Also, Fossil uses SQLite, so anyone (including myself) who is using Fossil repositories also has SQLite. And many other programs also use SQLite for their own data, including Firefox and many others.

The "light khaki" is definitely "yellowish", whilst the "dark khaki" is someewhat more "greenish".

It is entirely possible that the confusion, at least in English, came continuing to call khaki the uniforms even if the colour was actually later changed to a grey green called "olive drab".

I'm sitting on a Mira right now and I have a Mira at work. I used to have an Aeron at work also so I would recommend either one.

I have used Steelcase chairs and those are great too.

I know how views work in several RDBMS, and I don't think that description lines up with what I understand.

> That is to say, it doesn't stupidly requery the whole base table each time, nor is there any risk of inconsistency

I mentioned materialized views, but then you mention the base_table. I think this statement is inaccurate whether it's a materialized view or not:

1. With materialized views as implemented by PostgreSQL and MS SQL Server, it doesn't query the base_table, it queries an artificially generated table. In the case of PostgreSQL, that table will be out of date (inconsistent) the moment there is a change to base_table. A manual refresh is necessary and expensive every time the view becomes inconsistent.

2. With non-materialized views, you are incorrect with at least PostgreSQL and MS SQL Server, the view does not "cache" its filters or joins or clauses. The view just functions as a query modification, and it does in fact query the "base table each time".

I think what you need to satisfy your requirements is actually a filtered or partial index, of the form:

CREATE INDEX latest_idx
ON base_table (some_base_table_keys, ...)
WHERE record = latest;

That index will be consistent and will keep the query optimizer from, as you say, stupidly requerying the whole base table, as long as the criteria holds and the keys your searching for are a prefix of those keys.
This is also why US CO2 emissions have been decreasing for years.
Second handed Aeron. Also, no matter how good the chair is, you'll need to take breaks, get up and walk around every now and then. We're animals that require motion. Our bodies have simply not evolved to be sitting for long periods of time.

Finally, your chair is not the only component in being comfortable. I recently discovered that my knee pain was because my setup wasn't fined-tuned to my height. This website[1] helped me to tweak my setup and now the knee pain is gone.

You can get the Aeron's on Ebay for under $500.
After owning one for a while they are nice. Quality is decent but I think they're overrated for their "new" price. As with many popular things, you can search for the word followed by "sucks" to find plenty of legit complaints. The pressure under your thighs is the one I find the most annoying.

That said, I'm overall happy with my used one I own. I appreciate that it's popular enough that I can replace arm rests when they get worn out.

I have it paired with the Autonomous.ai standing desk frame, a cheap Amazon desktop & a cheap standing mat. I like this because sitting for 6-10 hours a day isn't ideal for me, but I understand for some people standing isn't an option.

I enjoy my setup more than any office one I've ever been in.

Steelcase Leap is an amazing chair, but more than $500 (or at least it was when I bought mine). I tried a bunch when I finally decided to upgrade from the $200 Staples chairs that wear out in a year and found this one the most comfortable by far. Have used it for a few years now with absolutely no complaints.

This is a seriously awesome piece of work. The mathematics in the paper are pretty dense but if you're ok with vector calculus its not too bad.

The implication here is that you can build lenses that have a consistent focal plane across their entire surface. A pair of glasses made this way would have crystal clear vision regardless of your 'look' direction (as an example). It also suggests that you could build lenses for lasers that were much more consistent, so a laser projector could project an in focus image from edge to edge rather than "fuzzing out" at the corners.

You cannot go wrong with most Herman Miller chairs. I originally started researching chairs because I have was having severe back pain. After several doctors appointments I found the cause, my old Ikea chair. I ended up going with the Mirra 2 and fell in love with it. It completely solved my back pain within two months. The price can be off-putting so I recommend checking out Design Within Reach's outlets (owned by Herman Miller) where you can get Aeron's and Mirra 2's for half off. Hope this helps.
It's not actually the thrust MCAS counters; that is counterable by elevator alone. MCAS counters extra lift generated by the nacelles shape and position at high Angle of Attack. No thrust is required to reproduce the aerodynamic effects MCAS is intended to counter.

That's why this damn kludge of a system is so concerning. It's an active airworthyness hack to counter a passive aerodynamic characteristic of the airframe.

So if a double flameout occurs, killing all power, and killing the Flight Control Computer due to unreliable voltage being supplied from the Ram Air Turbine, the pilots are stuck flying a glider that'll try to pitch into a stall on them if they aren't careful.

Again, normally wouldn't worry about something like this, but they missed/intentionally left out the single AoA sensor...

So...yeah... I have severe concerns about this design, and the effort put into known, unlikely, but highly severe failures.

If by "zone" you mean "flow," then yes; here's a relevant quote from Deep Work:

> The connection between deep work and flow should be clear: Deep work is an activity well suited to generate a flow state (the phrases used by Csikszentmihalyi to describe what generates flow include notions of stretching your mind to its limits, concentrating, and losing yourself in an activity—all of which also describe deep work). And as we just learned, flow generates happiness. Combining these two ideas we get a powerful argument from psychology in favor of depth. Decades of research stemming from Csikszentmihalyi’s original ESM experiments validate that the act of going deep orders the consciousness in a way that makes life worthwhile."

Steelcase furniture can be bought at pennies on the dollar at office space auctions.

In fact in many places companies hold “clearing sales” to clear the office space from any furniture due to the high costs of disposing of the furnishings when their tenancy ends or when they sale the building.

I bought a Steelcase workstation desk complex that costs around £3000 in the UK for £257 at an auction such as that.

I was getting my Master's in 2003 and Haskell was very hot amongst all the professors and students who were into functional programming.

I learned it because of group projects where we could pick the implementation language and that's what our group wanted.

At that time, Simon Peyton Jones was employed by Microsoft and, at least as I perceived it, was allowed to work on ghc full time because of the goodwill it generated amongst programmers for Microsoft to be the patron of Haskell.
He dismisses type-theory research as irrelevant because he doesn't think strong typing plays well with macros. This could probably be considered a jab at Haskell and similar languages.

Hmm...go back and look at how the Theranos debacle played out.
For me, their business model was the biggest turn-off, I didn't even give it a try because of that.

Hearthstone is already strong in this market, they have $0 entry fee and only charge for the cards. It's a pay2win game, some like/accept it, and some don't. I don't. Because I'm not willing to pay some unknown amount of money for a game just to stay competitive everytime the meta changes. I play games for fun, and being destroyed in a game because of IRL money is no fun.

Now what I would consider as a strong alternative to Hearthstone, would be a game asking for a triple-A entry fee, and then charging nothing extra. In this game everyone would have the same chances, and nobody would have to feel bad just because they didn't invest enough money in a gambling scheme.

What Valve offered is a triple-A entry fee, and then charging for anything they can. Now how is this can ever be a good offer? I don't know. I simply ignored the game and moved on.

The worst bug I ever introduced was when refactoring duplicate code.

I was refactoring handling of dates. The code was littered with date handling that was not thread safe and duplicated all over the place. So. I made it thread safe and pull it all out into a central place. But while doing so I accidentally introduced a new bug that then hit every single time dates where being handled. Which was all the time. Several thousand times per minute.

Oh my. The cleaning up we had t do after that.

The lessons I learned was: 1. Don’t be so eager to refactor code.

2. If you refactor repeated code you are introducing a single point of failure. Make sure it works.
True, although in this case it's an non-issue because most attributes for humans follow a normal distribution.
Perhaps an uncomfortable chair would be actually better, because it will nudge you in the direction of taking breaks more? I think office chairs are a rabbit hole just like mechanical keyboards are. Many people will be comfortable with the cheap option, while others will tell you you're risking your health by not going for the highend option.

That'll likely depend on the definitions of trade and winning/losing.

If you're starving and I'm the only one around and I sell you a loaf of bread for a million dollars, did we both win? Sure, you'll live another week, but I sold you a bread that you'd usually pay a few bucks for and got a million in return.

If I'm paying the mafia for protection, do we both win? Sure, my restaurant doesn't burn down, but if the mafia didn't exist, it wouldn't burn down either.

What about forced trades without perceived value, like a mandatory membership in organizations whose services you don't care for? What do you gain, besides not being thrown into jail?
