It’s not normal to be constantly afraid of anything. That’s not healthy.
It’s normal and advisable not to completely trust the government, but being constantly afraid is paranoid.
Because the tire is topographically a radially flattened torus, when you turn it half inside out, it becomes a 2D möbius strip. At this point it effectively has only one side. When you push such construct horizontally against a solid, because the z-axis perpendicular to the strip has no negative values (it only has one side), if that coincides with the orientation of the ∇Np of the solid, the z vector wraps around the solid. When the tire snaps to its rest state (inside in), it’s easy to see why it ends up around the pillar.
This 3D animation demonstrates the concept:
I’m a 55 year old senior developer. I’ve been coding since I was 12 (yeah, RPG II in punch cards and COBOL stored in 8" floppies), and I have a TERIBLE memory.
Don’t bother memorizing and knowing every language feature and detail. Just get a general awareness of what it can do. Then when you need to accomplish something, it’s good enough that for the first times you do it you go “hey, I recall there’s a way of doing it” or at least (often happens to me) “hmm, this sounds useful enough that this language must have a built-in way of doing it”. Then you google or ask some AI, and you’ll get pointed to the general direction most of the times.
Then if you use it often enough, you’ll remember it. (and in my case, if I don’t use it for 3 months, I completely forget about it, and even get surprised when I see how I did it in my own old code).
In the old days, you could indeed know every feature and library (if any existed at all) of a language. Heck, I knew almost all hex op codes for the Z80 assembly by heart (still recall more of those than I recall my relatives names). Nowadays it is impossible to memorize everything.
In JS realm, if you look at the amount of components you have available in most frameworks, for example in UI5, or existing node modules for your node.js project, even trying to “memorize” them all is a waste of time. In cases like this, you just need to assume there’s a component or module that does what you need, then be good at finding, choosing, and understanding how to use one.
Not to mention the reduntant stuff they throw in “modern” languages, like javascript’s forEach. Some languages have 10 ways of doing the same thing, each one 0.1% more efficient for each particular case, but may catastrophically fail in some other specific case. Screw it. Learn the one that works well for every case and stick with it - you’re not coding ultra performance critical stuff in js anyway.
Programming today is usually more an integration of functioning pieces than building from scratch (assuming that if you’re talking about JavaScript, we’re not talking about creating microcode for bare silicon).
Worry about building an efficient and robust logic in your head. Then the programming language is just a tool, way less important than the logic you came up with.
…or to a diabetic person whose health plan does not cover all the insulin cost they need.
I should have specified that I was referring to superfluous stuff.
For basic needs like education and health, any cost is too expensive. That should be sponsored by the whole society and government, and be free.
In some cases, they are. My bachelor’s degree (5 years Engineering) costed me zero (in monetary units). Even the printed material was free, from the uni printhouse.
We also have the largest free universal health care system in the world, and it’s even pretty decent in some regions of the country (Brazil).
I’ve never used them.
If I like an app or site, but the ads are annoying me, I do one of these:
-
If there’s an option to pay the creator/aggregator to eliminate the ads, and the cost/benefit is worth it, I’ll pay.
-
If there is no option to pay, but the app/content is worth the ads annoyance, I’ll keep using the app/site and watch/skip/ignore the ads.
-
If there is no option to pay, or there is, but the price is higher than what I perceive as the app/content value, I’ll stop using the app/site.
For example, I paid for Baconreader Premium, but I watch YouTube ads, and I removed several sites from my google home page feed because they had more ads than content.
I’m also stop using Reddit, as I don’t think it’s worth enduring their obnoxious native app.
And no, I don’t use pirated software, nor watch or listen to pirated movies or music. If something is priced above what I consider it’s worth, I just don’t use it.
Yes, Baconreader Premium could be consider as a “reddit ad blocker”, but it operated within Reddit’s approval. Now Reddit changed their rules, and it’s their rules.

So many. Unfortunately most of you will miss the lyrics, which are real poetry. Here are a few:
A rosa (1917 song by Pixinguinha, rendition by Marisa Monte in 1991)
Bahia com H (1981, João Gilberto, sang by himself, Caetano, and Gil)
Luiza (1987, Tom Jobim)

You answered “trying” as something that “is ALWAYS worth it” - which was OP’s question.
If you now say you need to “weigh the pros and cons” - which I agree - then trying it’s not ALWAYS worth it, no?
Then as someone else commented, each person has their own risk tolerance, so once each person weigh the pros and cons, trying will be worth it for some and not for others.
So answering “trying” to “what’s something that’s always worth it” is rather paradoxical, as what you probably meant then was “trying it, but only when it’s worth it”.
It was not the most important thing for me, but I agree: 15-20 years ago, veg options (and sugarless too btw) sucked. You really had to be committed to the cause to endure them.
We’re not vegetarians, but my daughter has allergy to eggs and milk. We buy cakes, pies, brownies, cookies, etc from a vegan bakery that honestly are delicious - better than most non-vegan equivalents. We all end up eating them, although only she actually “needs” them.
If vegan activists worked more towards kindly creating and showing the world vegan options that are as good as/better than their animal counterparts, it would help their cause MUCH more than pestering people, destroying property and making everyone hate them.
But if you ask yourself “what’s the worst that could happen?” you must realize that sometimes trying is NOT worth it.
Like this guy, for example:
Yes, back in 2009, after a kernel update to 2.6.26 there was an intermittent and hard to reproduce problem with Intel’s e1000e ethernet linux kernel module. It only happened when some specific switches/hubs were connected to the interface; the interface would initialize in an unusable state (about 50% of the computer boots).
The e1000e module was used by a lot of Intel onboard ethernet interfaces, including the one used by Dell Vostro computers.
I found other people reporting it in the kernel’s bugzilla, and added my case.
The Intel developer couldn’t reproduce it (he didn’t have one of the switches that triggered the problem), so he asked me to use bisect to help narrowing down to the commit that started the problem.
Because it was an intermittent issue, I wrote a script to reboot the PC multiple times on each bisect try, to eliminate false positives.
(I didn’t remember all these details, but googled my name and bisect, and found the bugzilla thread; it’s an interesting bisect use case: https://bugzilla.kernel.org/show_bug.cgi?id=11998#c8 - no I don’t mind this associates my lemmy user name with my real name).
The bisect did locate the culprit commit, and after many other tests, it ended up being an issue with the MDI/MDIX (crossover or straight connection detection). The correction was pushed into the kernel.
Bisect definitely helped to find an important and otherwise difficult to find problem there.
IDK, but it took me a good 30s touching the posts in your screenshot trying to figure out wth was happening.
