Caveat programmer: this could be problematic, not in the sense it doesn't work, but in the sense that someone working on backend code may have a preconceived expectation that UUIDs are also effectively a keyspace i.e. they're hard to guess. The validity of that is already challenged by variants defining temporal or logical order, and evaporates completely if you let clients declare their own that you accept at face value. Applications may have potentially guessable/gameable object identifiers sloshing around inside as a consequence, which is modestly ironic given that one benefit many folks expect from adopting UUIDs in the first place is hardening up the attack surface of trivially enumerable sequences.

There are a few mitigations but my favourite is the "casino chips" approach: pregenerate them server side, and allocate to clients on demand, including en masse if need be ("here kid, have a few million UUIDs to get you started"). Verify with whatever simple signature scheme comes with your application server framework, or at small scale just toss them in a crude LRU store.

Or, remember where the UUID came from, and apply their organisational scope to any trust you place upon it. This might work particularly for multi-tenanted SaaS. However it requires that all usage is tenant-bounded end-through-end throughout your application. This may be in conflict with a) your framework, b) your zenlike contemplation of simplicity in data management, or c) programmers in a hurry forgetting to scope their queries properly.

Ultimately, relying on UUIDs as intrinsically unguessable security tokens is probably not a great idea, but it's one that remains thoroughly embedded in the programming zeitgeist. As ever, nothing useful comes without a compromise. Keep your eyes open to the systemic consequences of design choices, and don't leave traps for your fellow developers.
My HOA has rules designed to prevent blue collar people from living in the neighborhood. No work icons on any vehicle parked outside a garage.
They can't keep you from moving in, but once you do, they can nickel and dime you with fines and make your life miserable until you move out.
Most HOAs have enough legalese baked into them that they can even hold eviction over tenants heads. It's absolutely a class weapon that gets used as a bludgeon. And if they can't technically evict you, they sure can make your life hell until you leave. Selective enforcement is the name of the game with these types.
Exactly. There's a ratchet effect to this. Economies of scale mean it's easier to keep something going than it is to start it anew once it's gone.
Exactly - I have 0 issues with mine either. I'd love to build a big garage in the yard, but I realize I can't for the better of the neighborhood aesthetics, and I'm fine with it.
The Mississippi mouth would have already moved to Morgan City if not for the Old River Control Structure.
I hate HOAs, but if all parties involved agreed to this "contract", the Government shouldn't tear it up and throw it away.

Similarly, while I am for solar panels and flying the American flag, I don't like politicians who pass laws forcing HOAs to allow both:

https://www.flsenate.gov/Laws/Statutes/2011/720.304#:~:text=...

and

https://www.solarunitedneighbors.org/florida/learn-the-issue....

I feel if I was smart/savvy enough to buy a home where I'm allowed to fly a flag or have a solar panel, the people who agreed not to should have to suffer with the devalued property they chose to create.

Because you said so in System Preferences.
Well, this example is a bit extreme. There’s some nuisance behavior that is made illicit on the basis that it is harm to the public as a whole. Having people defecate on your front lawn in view of everyone probably runs afoul of something in most jurisdictions.

What happens behind closed doors is mostly still fine, though, even though it can lower property value. A lot of things can lower property value that aren’t fair to you, and the mere fact that they happen doesn’t mean you personally were wronged nor does it mean anything illicit has happened. Could be a nearby factory shuttering causing the local economy to struggle, or something.
I'm still smoking at the moment.

I've quit for years and started again.

It's the push and pull .. the need and that satiation that I find so satisfying, and to a certain extent it's that rhythm I find ultimately attractive.

The slow build up of a hunger, before you end it with a delicious meal. The relaxing bath after a 30 mile hike. The 10 hour sleep after a stressful few days running on caffeine. The buzz of endorphins after breaking through the pain barrier on a run.

Unfortunately, I'm a bit of a junky at heart. But I would like to stop smoking.
That sounds like a pretty good deal. But are you really protected from a new board being elected to the HOA and the board instituting restrictive rules and increasing fees for the "common good"?
I opt into personalization and am constantly getting ads for tampons (not a woman), essential oils (yuck), iced tea (I only drink water), chinese clothing (lol), and then sporadically...

100k+ metal 3d printers and other industrial engineering equipment. I am a disabled, unemployed student.

I also have serious doubts that "personalized" ads even really exist. It's like they're trying to show me the least applicable products to my life.
This does not match my personal experience. I live in a 10,000 person neighborhood that is covered by an HOA, and it is a very diverse place. In fact, one of the things that I like about living here is that there are people from all over the world living here.
> That quote is about sharing knowledge not about educating people.

So what is educating people, if not sharing knowledge?

> Different things with different requirements, a different (related) activity.

That's one way of looking at it. Another is: Just different words for the same thing.
> but you'd still be missing the point.

No, I don't think they are. The key thing is that you sign the papers and so does everyone else.
Right, they have formal laws that cover the things an HOA in the US would normally prohibit or restrict.

Go mow your lawn on Sunday in Germany and let me know how long until someone tells Ruhetag at you.
My old HOA was $20/month in SoCal and got me access to the community pool with well maintained lawn around it. The HOA was basically powerless otherwise. We tried to use it to stop an old, reclusive guy from feeding crows and releasing his pigeons(literally blanketing the surrounding backyards with bird shit), but they couldn't do anything.

HOAs vary quite a bit. The older I get, the more I want to live in a strict HOA community though. I want the stability and improved neighbor relations(the HOA is the bad guy, not me, when the neighbor stops maintaining their property).

I understand why people don't like HOAs. Yes they were born out of racism. I don't think that invalidates the concept.
Setting aside economics, James Madison developed an interesting categorization of systems of governance, based upon their method of obtaining civic energy, which seems rather timeless:

Where do you (personally) draw the line at material harm...? We already have a system (the courts) for redressing material harms.

Many HOA bylaws (house color, RV parking, minimal landscaping requirements, etc etc etc) aren't material harms. They are "harms by association" -- e.g. my house value goes down because you have bad taste in paint colors. Hence "Home Owner Associations".
> Nothing has corroded my belief that humanity is capable of governing itself in a sane, common sense manner, as much as serving on Strata (Canadian version of an HOA for a condo building) for several years.

People cannot govern without injecting extreme bias. With regard to something like home ownership, I'd like my home to be subject to only my own biases. Power corrupts absolutely, even at the smallest scale.
How many people are actually effectively organizing their data in files? If a system doesn't work for vast majority of users, then it does deserve rethinking. Its great that desktop model works for you, but I strongly suspect you are not representative of the greater user base.
Property taxes can go to _those people_ who can't afford to live in your burbclave.
Yup! In a similar vein: My old HOA didn't allow you to have vehicles parked on your own driveway after 6pm until 6am.
This is comment is unhelpful in the extreme.
People vote for the co-op board members. Why not vote the people out?
Done it many times, no problem. People who say "there are no HOA neighborhoods" typically mean there are not any neighborhoods that don't have HOAs but look like those that do have HOAs.
Yes, but the much quieter, battery powered electric ones are lighter and more powerful. Anyone not using electric leaf blowers at this point is just being a cheapskate. And considering the lower or nearly non-existent maintenance, they aren't even being a good cheapskate.

Anyone in a position to do so should require in their lawn care contract that only electric leaf blowers or none at all must be used.
I was a half-pack-a-day smoker for about 10 years, quit several times (once for several months), and the only thing that "worked" ultimately was realizing that I simply could never have another cigarette. After the physical cravings subsided, I still had frequent longings for that wonderfully ubiquitous way to 'fix' my internal itchiness/discomfort, but I had made such a commitment that I would have literal nightmares in which I smoked a cigarette--and then woke up in a panic, similar to dreams where I found out I'd accidentally killed someone and was debating whether to turn myself in or go on the lam.

Then one evening about 10 years later I was at a festival wandering around and I had this desire in my brain for something, I didn't know what, and it was a few hours later that I realized the thing I really wanted was a cigarette. It was that night that I changed my internal conception of myself from "ex-smoker" to "non-smoker". I don't have cravings any more for cigarettes, though there is a certain pang, I guess I would call it "nostalgia", and maybe it includes "envy" of people who can smoke a cigarette/cigar socially at an event and then not think about it again for years. Occasionally I will have accidental contact with nicotine (like buying a joint on vacation and getting a weird taste while smoking it and realizing half-way through that it's actually a spliff), and for a few days or a week afterward the light switch is again visible in my mind--though I'm thankfully not tempted to flip it. I wonder in those times whether a never-smoker who has a cigar once does have the same cravings in the days after, but doesn't recognize them as such.

So at least for me, who admittedly was never a heavy smoker, it doesn't resonate that I will struggle with this addiction until I die. The only apparent lasting (mental) consequences are that I have to consciously refuse nicotine even when it would be a legitimately fun and interesting experience (like when I was offered some fancy snuff at a party which everyone else got to enjoy). And when I see someone smoking a cigarette I might get the nostalgia or envy I mentioned above. But when I get within smelling distance it's just foul and unappealing.

Best wishes for anyone who's thinking of or trying to quit.
Good for you.

Sorry I don't have a better analogy, but it's like coming home from a tour in the military, and telling everybody "hey guys, war is perfectly safe, look at me I'm still alive!" — I'm really happy for you, but others are going to listen to your "story", follow your example, and have drastically worse results.

I think it's more interesting learning from those that went through hell, not the reckless lucky ones that managed to stay unscathed and think they're hot shit. Luck ain't a skill nor wisdom.

I know these are strong words for the matter at hand, but there must be an ex smoker or three that know exactly what I'm talking about.
Question out of curiosity:
I’m German so I don’t know the US law that well but don’t you for example have laws that forbid being noisy after a certain hour of the day?

If my neighbours were throwing a loud party past 10pm I could simply call the police/ Ordnungsamt (police light) and they’d tell them to quiet down.
By this argument nobody owns anything because there is always some level of state authority that can make rules about what you’re allowed to do with it. What’s the fundamental difference between an HOA and a small local government?
The difference is that you only need the local neighborhood to agree that it wants a well maintained park, not the city, which may have other priorities.
It can actually be even weirder. The land might be worth -$money (in some cases like Detroit, tax liens and other issues meant the ‘$1 house’ was actually $50k+ because of the liens.)

And yes, no sane bank is going to lend against collateral that is fundamentally worthless. Construction loans are problematic because the property can be worth -$$$ if
say the work isn’t finished and the builder starts putting (western concept, not sure how
it maps to Japan) builders liens on the property for all the work they did, and then it all rots because no one put windows or a roof on it.

These properties are at these prices because they are currently fundamentally not worth more. They sit on the market because they won’t even sell at that price.
I think parent was wondering what the word "accelated" in "software-accelerated" could mean. Faster than what? (faster doing the calculations by hand? :)
I'm genuinely glad that is the experience you've had. I hope that model would be the one that's more common.

Unfortunately in my experience it's the exact opposite. Here they're used and abused by exclusively rich, mostly-white neighborhoods to keep them that way.
I wonder if HOA neighbourhoods are cheaper for the city?

I could imagine costs of policing being lower and various kinds of complaints being dealt with by the HOA before it gets up to the city.
The mundane answer is that you don't necessarily have a choice within your desired combination of budget + location + quality + ...
> it's obvious that ... painting your shutters the wrong color is on the other side of it

It might be obvious to you (it's obvious to me too), but it was manifestly not obvious to the board members who voted to enforce the shutter-color policy, nor to the people who voted for them.
I absolutely have not. But I don’t think the possibility of buying tracking ads is somehow excused because e.g “you couldn’t start internet businesses otherwise” or even “most of the free content online would disappear”.

Targeting doesn’t have to imply tracking or trading in my info. Facebook knows my age and gender, and some of my interests (from groups etc). That should be plenty. That means a company that sells kitchens can’t target people “interested in kitchens” in the sense they have recently searches for it or visited a site of a kitchen manufacturer that told Facebook. They can target people in country X of a certain age. If that doesn’t sell enough kitchens then just close down me kitchen business or buy a bus stop ad but don’t follow me around the internet.
There rules with owning almost anything. HOAs are on the far end of the spectrum, but you get the appreciation if property values go up, which is one of the main reasons for owning property
Most of the non-sketchy reasons are related to iOS Safari being crippled.

For example, I worked on a rich text editor, and we wanted to put a bar with text formatting tools above the touch keyboard. This is not possible in the browser: your webapp cannot measure the keyboard or the remaining available viewport (and the keyboard's size depends on the input method and the iPhone model).

Another example I experienced is when we wanted to have full-screen dialogs with buttons at the bottom. If you do that, then the users have to tap your buttons twice, because the first tap only expands Safari's browser UI, and your buttons near the bottom of the screen only work while that UI is expanded.
Treating it like an investment IS the prudent thing to do. Is vs. what you want it to be theoretically are 2 different things.
Of course it's manipulation. Ads are made in order to modify your behavior in the benefit of the brand. That's literally the definition of manipulation: to control or play upon by artful […] means especially to one's own advantage; controlling someone […] to your own advantage […].

> why do you feel that voluntarily purchasing something based on an ad is “manipulation”?

There's nothing in the definition of manipulation that says it has to be involuntary.
Search ads are very effective and are paid on a per-click basis, so you really can't go wrong with them.
>> I've lived in a few different countries and I can't think of anything as opressive to your homeowner rights as American HOAs.

Try Japan. Could tell you plenty of stories, but patio11's stories about being an entrepreneur and trying to rent an apartment sum it up pretty well.
Sounds like the HOA people were angry they didn't win...
I'm sure there are extremely strict HOAs out there with insane people on boards that horror stories originate from.

We've always lived in HOA homes (in our 4th now) and they have all been very laid back.

This kind of HOA I belong to is basically the "anti-hillbilly" HOA. You aren't allowed to own 50 cats and dogs free roaming and crapping everywhere, don't leave your rusted out broken down beater in the front lawn, don't let your lawn go to 4 foot weeds (but by all means grow some 6ft tomato plants), your backyard is not your personal firing range, you aren't allowed to have a personal dump of trash that you clear every 6 months, etc.

Our HOA does are for snow/ice services, long term repairs on our private road, and the front entrance maintenance.

Every house is very distinct, some I don't prefer the styling/color, but I enjoy the diversity way better than a cookie cutter subdivision.

Soul crushing to me are people who don't take care of their property and enjoy living in neglect (which plenty of people out there manage just fine without an HOA, I just dont want to roll the dice)
That could be an exception. However, when I hear "HOA", the kind of neighborhood that comes to mind is "insipid, yet pretentious suburb".
You also can't discharge a gun pointed at another human, or even in most public places, so do you really 'own' that gun?
And they absolutely will. After I moved out of my last HOA, I found out the towing company had a flat rate kickback to the HOA organization for every tow they made. Genuinely baffles me how it's even legal.
Pipes can give a car a cool sound. But most people like music too. But they sure don't like it blasted at all hours of the day and night at random intervals.

Fun fact: in Windows, the location of the Desktop is dynamic and can be changed via SHSetKnownFolderPath. This allows you to display the contents of any folder in the desktop.

Years ago I made a gadget that sat on the top right corner of the desktop[1]. It contained a stack of buttons, one for each folder that I was working on. You could add more folders by dragging them on the gadget.

It's liberating not having to keep a file explorer window to access the current project, and you can easily access it with the Windows+D hotkey that minimizes/restores all windows. Use it to open files, or drag stuff to/from other open applications.

# Requires pywin32

shell.SHSetFolderPath(shellcon.CSIDL_DESKTOP, 'C:/new/path/', 0)
shell.SHChangeNotify(shellcon.SHCNE_ASSOCCHANGED, shellcon.SHCNF_IDLIST, [], [])
With what? I am painting a viewpoint against HOAs.

edit: I think I understand why people are reading it this way, so I added a bit onto my original post.
People also talk about buying stocks but you also can't control the direction of a company as a minority shareholder. People also buy non-physical things like music or software, and things that exist only for a moment in time, like experiences.

It would seem that most people's definition of "buying" works for HOA-controlled properties. What's your definition?
(To the OP title: More expensive than disaster?)

Many comments here relate more to one-off design. There is also the medium-high-volume manufacturing end. There, a prototype run might be in the dozens or hundreds of units, more than the entire manufacturing run in other heavy industries.

As the OP hints, "safety factor" is not the only term to use. A design margin (including reduction in margin) can be planned with one or more motivations: safety, reliability, weight, volume, reduced BOM costs, unit costs of repair, fleet costs of repair, logistic and warehouse costs of parts for repair, planned obsolescence, and so on.

Probabilistic design, also realized through "Monte Carlo" analysis, can take into account multiple simultaneous non-linearity in various models, where symbolic or formula-based analysis might fail.

For example (and roughly speaking), if one has millions of miles of over-the-road data, say of wheel-to-road forces or geometric road or track profiles, then one might manage to calibrate the following together: 1) a specific vehicle physical model, including parts tolerances and probabilistic discrete flaws; 2) material cycle-fatigue damage properties; and 3) some set of Weibul-distribution-like parameters as an intermediate in predicting failure rates and "lifetimes." .. AFAIK the kind of business analysis one might do could include predicting how many parts one should overproduce and warehouse (in a one-time batch) to service in-warranty and post-warranty repairs out to N years.

At that scale it can also become sociological. "Safety margin" is a loaded term when it comes to liability and imprecision in intent. You reduced the safety margin, as it says right here?!!

Not a bad article, but there could be a whole article on ramifications of different margin-related wording, high-N statistics, and explicit accounts of simultaneous goals.
To be fair, some American Admirals believe in battleships fleets slugging it out. I cannot remember which battle, but it was basically caused by an American Admiral moving his BBs for just such a battle.
