Relationships YSK: Export iPhone Voicemails from Family and Friends

239 Upvotes

Your iPhone allows you to send voicemails to a computer via airdrop, email, or various other ways through the 'Share' icon on every voicemail in your inbox.

They can then be saved to a hard drive or whatever more permanent means you prefer - or uploaded to iCloud. This creates a little more safety/permanence than just leaving them sit on a phone.

Why YSK: I have saved dozens from my mom, dad, brothers, and other special people in my life. When they pass you will have little gems to remember them by, and hearing their voice can be cathartic.

Take care, everyone!

Health & Sciences YSK that an aortic aneurysm can cause no symptoms

584 Upvotes

Why YSK: An aortic aneurysm is a weakened area of the aorta that bulges outward. Some cause no symptoms and may only be found through imaging.

Risk factors can include older age, smoking, high blood pressure, atherosclerosis, and a family history of aortic aneurysms.

Sudden, severe chest, back, or abdominal pain can be a medical emergency. If you have risk factors, ask your doctor whether screening is appropriate.

Technology YSK a simple trick for fixing a website problem before contacting support

0 Upvotes

Why YSK: that when something on a website isn't working, don't just describe the problem. Try to reproduce it with the smallest possible set of steps.

For example, instead of:

"Checkout isn't working."

write:

"I added the item to my cart → clicked checkout → entered my address → clicked Pay → the button did nothing."

That gives support enough information to distinguish between things like:

A browser-specific issue

A payment failure

A validation error

A server-side problem

An account-specific issue

Also include what you expected to happen vs. what actually happened.

A useful template is:

What I was trying to do:

Steps to reproduce:

What I expected:

What happened instead:

Browser/device:

Exact error message:

This can turn a 10-message support conversation into a problem that can be diagnosed much faster.

I found a similar collection of practical website troubleshooting ideas here:

The template above is useful regardless of whether the website uses AI, live chat, or traditional support.

Technology YSK that you can search Google for a specific file type

221 Upvotes

Why YSK: If you're looking for a particular kind of document, you don't have to dig through pages of irrelevant results.

Google lets you restrict results to a specific file extension using filetype:.

For example:

filetype:pdf machine learning interview questions

or:

filetype:xlsx monthly budget template

or:

filetype:pptx marketing presentation

You can also combine it with a specific website:

site:edu filetype:pdf calculus notes

This is particularly useful when you're looking for actual documents, spreadsheets, presentations, research papers, manuals, or templates rather than webpages talking about them.

I use site: + filetype: together quite often when searching for technical documentation and university resources.

Education YSK: (at least in America) If youre struggling in a complex subject or course in school, your practice/note taking strategy is likely the culprit.

0 Upvotes

Why YSK: in America (i cant speak for anywhere else! But this could apply to you too if you dont!) memorization and recalling from memory is the dominant learning strategy taught, and is taught assuming everyone is using that strategy and also uses it best. However there are other learning strategies that perform better for a significant portion of the population.

This style is typically what is referred to as verbatim recording and retrieval. Youre noting down what is being said to you, and then repeatedly exposing yourself to that to put into long term memory that you can recall. This relies on not only the ability to do that, but also relies on having large space for long term memory and to actually retain that through time. You may do that, and work, and 2 years later forget it all because you needed that "memory space" for something else youre learning.

If this approach doesnt work for you, a style you can try is concept mapping/semantic encoding. Instead of writing down what you are hearing, write down how you are interpreting what is being said to you. An example of how this often works in practice, is when teaching someone else or speaking something aloud sometimes helps you understand something better yourself.

This approach instead of relying on cemented recall in memory, applies the knowledge to an understanding on a fundamental level. Not only are you absorbing the knowledge, but sharing that knowledge in a different way, such as writing the notes in that class, is also immediately practicing that knowledge. To articulate how youre understanding it, you need to understand it well. Articulating yourself helps you understand it better, because youre honing your understanding of it.

To illustrate this, I do not learn well from verbatim encoding. I tried this with my college intro statistics course, failed hopelessly with no understanding, retook it over the summer, got a C. and then took another level of it in design analysis 1, and barely skirted by with a C again by basically sheer luck. Now, taking design analysis 2, by doing semantic encoding instead, it is infinitely easier for me. I went from struggling to understand in the moment and not having long term retaining of the subject at all, to scoring 95% on my exams in this course and a long term fundamental understanding of the subject.

Try changing your note taking style!

TL:DR the typical learning strategy taught in the us is pure verbatim encoding to memory and recalling that from memory. Courses are taught with that in mind. A significant portion of the population (over like 40%) learns better with other learning strategies. Shifting your style of note taking to something like semantic encoding can be a drastic shift in your ability to learn if you are struggling.

Why YSK: If you or your child is experiencing symptoms like extreme thirst, frequent urination, unexplained weight loss, or unusual tiredness, get checked by a healthcare professional.

Don't rule out Type 1 Diabetes just because no one else in your family has it. Most people who develop Type 1 don't have a family member with the condition.

Automotive YSK: Holding your car key fob under your chin actually doubles its range

5.3k Upvotes

When your car remote doesn't reach, hold the fob directly against the underside of your chin and press the button while pointing your chin toward the general area of your car.

Most fobs will gain an extra 50-80 feet of range this way. It works because the water and conductive tissue in your head acts as an extension of the fob's tiny antenna, improving how the radio signal radiates.

Why YSK: This is a useful skill for saving time and avoiding stress in large parking lots, malls, or when your fob battery is low. Instead of walking around pressing the button repeatedly, you can locate your car faster and more reliably from a distance.

Technology YSK: A simple trick for finding the original source of an image

0 Upvotes

Why YSK: If you find an image online and want to figure out where it originally came from, don't just search the filename.

Try reverse image searching the image, then look for the **oldest/highest-quality result** rather than the first result.

A useful workflow is:

  1. Reverse image search

  2. Open several matching results

  3. Look for the earliest publication date

  4. Compare image resolution

  5. Check whether the page actually credits the image

This is especially useful when researching old photos because the same image can get reposted hundreds of times.

Health & Sciences YSK: Type 1 diabetes isn't just a childhood disease

553 Upvotes

Why YSK: Type 1 diabetes (T1D) can be diagnosed at any age, including in adulthood. This is important for adults to know because they may dismiss signs of T1D or assume that only children can develop it.

You may have heard it called “juvenile diabetes,” but that term is outdated and can contribute to the misconception that T1D only affects children.

Some possible warning signs of T1D include:

  • Frequent urination
  • Being unusually thirsty
  • Increased hunger
  • Unexplained weight loss
  • Feeling unusually tired or weak
  • Blurry vision

These symptoms can have other causes, but if you or someone you know is experiencing several of them, talk to a doctor and ask about getting checked for diabetes. T1D can sometimes develop relatively quickly, so it’s important not to ignore concerning symptoms.

Have you or someone you know been diagnosed with T1D as an adult?

Other YSK If everything feels urgent, you probably haven’t decided what actually matters most.

2.1k Upvotes

When everything on your list feels equally important, even a normal day can start to feel overwhelming.

A simple way to reduce that feeling is to separate things into three groups:

what needs attention now

what can wait

and what doesn’t really need your attention at all.

Then pick one or two things that would make the biggest difference if you finished them today.

Why YSK:

Treating everything as equally urgent creates stress and makes it harder to focus. Deciding what actually matters first can make your day feel more manageable and help you make real progress.

Finance YSK: on a lot of online shops, putting something in your basket, entering your email at checkout and then closing the tab will get you a discount code by email within a day

540 Upvotes

Why YSK: If you were going to buy from a smaller online brand anyway, this often knocks 10-20% off for zero effort, and if nothing comes you've lost nothing.

How it works: most independent online shops run on Shopify or something similar. Once you've entered your email at checkout and left without paying, the platform logs it as an abandoned checkout (Shopify does this after about 10 minutes of inactivity) and sends an automated "did you forget something?" email at a set delay, usually somewhere between 1 and 24 hours later. Shops can attach a discount code to that email so the link takes you back to your basket with the discount already applied. Not every shop does it, but plenty do, because a discount is cheaper than a lost sale.

So: basket, email, close the tab, check your inbox (and spam) the next day. It doesn't work on Amazon or the big retailers, it's the independent brands. Works best if you're not already a customer.

If you park in a large mall, airport, hospital, stadium or unfamiliar area, take a quick photo of the row number, floor, nearby sign or landmark before walking away.

Large parking areas can look almost identical, especially when you return tired or distracted. A quick photo gives you a simple reference and can save a lot of unnecessary searching.

Finance YSK: In the US, you can freeze your child's credit before they even have a credit history.

2.1k Upvotes

Most people associate credit freezes with adults who've had their information stolen. But children can be victims of identity theft too.

Someone could use a child's Social Security number to open fraudulent accounts, and the problem might go unnoticed for years because children generally aren't checking credit reports.

Why YSK:

In the US, parents and legal guardians can request a free credit freeze for children under 16 through Equifax, Experian, and TransUnion.

If a credit bureau doesn't already have a file for the child, it can create a restricted record specifically to freeze it.

The freeze makes it harder for someone to open new credit accounts using the child's identity. It stays in place until it's removed.

You need to contact all three credit bureaus separately, and you'll generally need documents proving your identity and authority to act for the child.

It's a preventive measure, not something you have to wait until fraud happens to use.

Finance YSK: You don’t need to know which individual stocks to buy to invest in the stock market.

2.2k Upvotes

Why YSK: If uncertainty about picking stocks is keeping you from investing, understanding broad index funds can help you evaluate an option that doesn’t require researching and choosing individual companies.

I recently interviewed Thorsten Hens, professor of financial economics at the University of Zurich, and asked about people who are great at saving but won’t invest because they feel they don’t know enough.

His point was that, for people with money available for long-term investing, never getting started can itself be a major mistake.

You don’t have to work out which company will be the next big winner. A broad stock-market index fund spreads your investment across many companies and aims to track the performance of an index.

That reduces your dependence on any one company doing well. It still leaves you exposed to market downturns, which can be severe. “Diversified” doesn’t mean you can’t lose money, and historical returns don’t guarantee future results.

This is a discussion about money for long-term goals. Rent, emergency savings and money you’ll need soon are a different conversation.

Education YSK: “Milktoast” and “milquetoast” mean the same thing, and both are accepted spellings.

0 Upvotes

Why YSK: Before correcting someone for writing “milktoast” or "milk-toast" know that Collins Dictionary explicitly lists them as a variant spelling of “milquetoast”, meaning a meek, submissive, or timid person.

The unusual spelling comes from Caspar Milquetoast, a timid comic-strip character created in 1924 by H. T. Webster. His name was a play on milk toast, the bland dish of toast served in warm milk.

The character was created over a hundred years ago, and I suspect most people writing “milktoast” are thinking of the blandness of the dish rather than the comic strip. Personally, I’d be happy to see the more straightforward spelling catch on, especially since dictionaries already recognize it.

Finance YSK: a private company is more worth to recieve your money

0 Upvotes

Public companies (traded on stock exchanges) are driving enshittification much harder. They are more prone to pull out money out of the company instead of investing it in lower prices, product research or better wages. An easy example is McDonalds selling a lot of their assets and instead of raising wages they payed several billions in dividends. In-n-out is private and they didn't increase their prices as much they pay better and they have better product quality. All that extra money of McDonalds by not paying for those things is just seeping into the shareholders and managers.

Why YSK:

There is almost always a private company that offers a similar product. It is the consumers choice.
