HACKER Q&A

Most life changing things that you bought?


Just reading about air purifiers and wondering what other things like this I completely missed in my life.

Personal recommendations: kindle, rice cooker.

Edit: It's so obvious to me now (and to most people I guess) that I forgot about my washer dryer. To other young adults reading this, if you can afford it and have the space in your apartment, just get a washer dryer ASAP. Even if you live 5 minutes away from a self-service laundry. It'll actually change your life.

Apple Watch - Allows me to view my blood glucose at any time.

Dexcom CGM - This is the best way to constantly measure your blood glucose, though it is a bit expensive.

Rileylink - This is an open source hardware device which intercepts BLE packets from my continuous glucose monitor and sends reverse engineered 433mhz communications to my insulin pump. This has a companion app (Loop) which tells me projected blood glucose on my Apple Watch and automatically administers insulin accordingly.

To a lesser extent, AirPods - it’s pretty cool to be able to say “hey Siri, what’s my blood sugar?” while I’m riding my bike.

When I first got the Apple Watch + plus rileylink setup it was like Xmas every morning ; I got to wake up and look at how my blood sugar had been successfully controlled by the system through the night. Taken together, this open source loop/rileylink system was probably the first legit artificial pancreas used by diabetics in real life. All the other data like insulin on board and active carbohydrates was so exciting to have directly modeled and displayed on my watch since I had spent years trying to estimate those variables in my head throughout the day.

Tickets to cart racing for the second date with my wife (back then future wife). I did not know she does not drive, and she does not drive now, but she carried through this with such a poise and good attitude that I realized she just might be the one.

Books - some of them were free, some of them bought, about mathematics, physics, chemistry, programming that got me hooked on these subjects.

Computers. Sinclair ZX Spectrum clone when I was in secondary school and my own PC that I assembled myself in university.

Contact lenses. I am myopic and used glasses. Contact lenses required some time to get used to, but ultimately gave me the great feeling of freedom.

Anything to support shared experience with people I love. It could be a ticket to the movies or a museum, meals in restaurant or for a picnic etc. The exact expenditure is not really important and it may be a good movie or not, but what matters is time spent together.

I moved to the US from a developing nation. For the first 5 years I was not aware of the dishwasher in my apartment (was using it to store utensils). I was familiar with washer dryers though.

One day one of my friends told me what it actually does and taught me how to use it.

Mind. Blown.

Chair. Never understood why somebody would pay for a chair more than 50-60 bucks. Something you can get in staples/wallmart anywhere... My friend bought Herman Miller for ~$1000 and I called him a donkey. Then started a job where we had these chairs in the office. Noticed it. Even back when I was broke, rented a room and didn't want to buy anything that would be potentially a problem to move, I still decided to buy it. I use it 6-8 hours a day. Worth it.

2) Higher quality kitchenware. knifes and frying pans. I actually had to go over few iterations cause even though I got more expensive ones they still didn't work well. Now, though, it significantly improved the quality/cooking of my food

3) High quality headphones/ear buds. Something about great quality sound makes it so much better to work out. I can run longer with proper soundtrack.

4) Car that I really wanted. I get behind the wheel and literally enjoy holding it my hand. comfortable/fast/smooth. looks sexy. It is an esthetic pleasure.

5) Very good laptop and widescreen curved screen. using them for work everyday - makes total sense to go with top of the line.

  I think it would very cool to have washer/dryer in unit. I don't have that. carrying a bag of underwear to another building in 2020 seems unnecessary.

P.S coffee maker. ~$700... I feel like it payed for itself in first month. I love coffee - it makes it itself. no standing around holding a cup of milk.

A cheap aluminium road bike (since replaced with a full carbon Felt).

At the time (10 years ago) I was 240lbs (been working stupid hours for nearly 2 years and pizza was easier on the way home) and the doc had just found I had stage 2 hypertension which he wanted to medicate, I asked him to give me a couple of months and if no improvement I'd take his advice, stopped in Halford's (bike chain in the UK) and bought their cheapest road bike for 400 quid, I resolved to go out every other day and fix my diet which I did gradually increasing distance/pace, at the end of the two months I was down over 10lbs and blood pressure was heading the right way and I'd got addicted to cycling, I signed up for a 200km overnight charity ride at the end of the summer (this was late spring time) and set about training for it properly working up to 80 then 100 then 120 mile rides until I was confident I could do it.

By the charity ride came around I was 190lbs and decided to treat myself to a nicer bike (I was too fat for the nice bike at the start, I mean literally too fat, it had a 100kg max weight limit recommended...).

In terms of return on investment that 400 quid bike was the based deal I ever made.


👤 PragmaticPulp
Extremely bright, high-CRI lighting for my home office.

I have extra lights I can turn on in the early morning to simulate daylight. This is far and away the most powerful tool for manipulating my sleep/wake cycles.

Even without seasonal affective disorder, an early morning dose of extremely bright light improves my energy and mood throughout the day. It also makes it easier to fall asleep at night because my circadian rhythms are further entrained.

> Just reading about air purifiers

I also bought multiple, large HEPA air purifiers for the house. I can't say I noticed any real differences. I keep them for peace of mind, though. I had better results with those adhesive strips that you put on your nose to open your breathing passages at night.


👤 TheHideout
Lasik eye surgery. It cost about $4k per eye USD due to how bad my eyes were. I went to a super reputable place and now have perfect vision. I can barely remember what it was like before.

Even better, I paid for them using money I made from my first indie game release. Was a huge emotional win for me.


👤 pelario
Therapy. Best use of money in my life.

You don't need to have a "big problem" (like depression) to visit a therpist.


👤 PascLeRasc
Possibly my Patagonia down jacket. I didn't grow up in a family that could afford nice winter jackets and always had a used ski-style winter jacket, which is really hard to move around in and not very warm. I didn't know it was possible to be comfortable in cold weather until this past winter.

👤 bitcurious
Vitamin D. Totally changed my life. Haven’t had a real bout of depression since I started taking it.

- Audible/Overdrive/LibriVox (I get through a lot more books per year listening to audio books as I do the dishes, etc.)

- Trash poker (Neighborhood/hiking trails are so much cleaner now, since I bring it with me wherever I hike and pickup trash)


👤 samvher
A pressure cooker. I originally bought it because I wanted to grow mushrooms and needed to sterilize the substrate, but ended up using it mostly for cooking. Lots of meals that usually take too much time are suddenly very reasonable to cook. I especially use beans and other legumes a lot more than I did before.

👤 ISL
At least for perspective alteration: Plane tickets.

The gut answer, though, is a pair of snowshoes. Much of the best of my life can be traced to that decision.


👤 yojo
Sleep:

- blackout curtains, blackout rod, and white noise machine.

- latex hybrid mattress. I settled on Luma's version of this.

Exercise: Mini home gym settup

- Bowflex SelectTech dumbbells with stand. Power blocks would be equally good, these were just on sale at the time.

- Cheapo belt-drive indoor bike

- Pull-up bar

- Bench if you have extra space.

Work:

- Ergo mouse and keyboard (I use Freestyle 2 for keys and Evoluent vertical mouse).

Liesure:

- Kindle with buttons. Used the old keyboard one until it died, then switched to the Voyage.

Car:

- Honda Fit. Incredible value in this car. Parks anywhere.

- Roof rack w/cargo box. Turn your subcompact car into a station wagon.

Cooking:

- Instant-read thermometer

- Vintage cast iron pan. They cost about the same and have a much nicer surface. Best I've found is Griswold.

- Forged knives with decent steel. Best value here is probably something Japanese (e.g. Tojiro Gyuto)

- Japanese water stone for sharpening. It's a fun skill and doesn't take long to learn - or just pay for it regularly. Sharp knives are life changing.

- Tri-ply pots/pans. I went for All-Clad, but Cuisinart seems to do fine for much less $$.

- Panasonic IR toaster (FlashXpress). Compact, super-fast , bulletproof. (I'm on year 10 of consistent operation).

- Moccamaster or knockoff version - I use the "Motif Essential" which sporadically shows up for $50. 85% of the flavor of pour-over, 20% of the work.

House:

- Battery-op electric lawnmower/blower/trimmer. No more gas fumes, low maintenance, quiet.

- Cordless drill

- Basement dehumidifier. No more funky smell.

- Color tunable light-bulbs. Bright blue in the morning, orange-y in the evening. It's flux for your house.

Health:

- allergies: sublingual immuno therapy. Same benefits as allergy shots, no shots.

- IR thermometer. Especially if you have kids.

A document scanner.

I had many years of old paper tax returns, and I wanted them in PDF format. Paid $400 for an Fujitsu ScanSnap iX1500 and absolutely love it. Put a stack of documents in the top, hit "scan", and a PDF appears on my computer. Zero hassle.

Anything that I get in paper form gets immediately scanned, backed up, and shredded.

For me, it was the VR game Beat Saber. I built my first desktop and got a VR headset just to be able to play it. I took 3 weeks off work December last year and lost ~10lbs (155lbs -> 145lbs) playing 2-3 hours every day. It's been great for me since I've been sitting in front of my computer all day for years and never really enjoyed exercising.

The Dash Pros

[RIP Bragi. You could probably substitute any other good wireless earbuds, though.]

This means I can learn and discover during activities where this was previously not possible.

Podcasts and audiobooks are available during commutes, flights, runs, bike rides, misc chores and errands etc.

The fact that they're entirely wireless, have very good noise cancellation (in-ear seal), a powerful touch interface, and are sweat/water proof, makes them especially useful. (e.g. skip song with double-tap while biking)

(Of course, use your discretion; shutting out the world and being always on the receiving end of information without time to process your own thoughts and letting them wander I think comes with a cost.)

Edit:

I'll echo what others have said as well: bikes!

Probably tied for first place is my bike which I bought off CraigsList in queens back in 2014. The decision to bike somewhere rather than driving/taking the train/walking means: new forms of exercise, new ways to discover a city, and it's fun :)


👤 greatNespresso
For smokers, the easy way to stop smoking by Allen Carr. Read it, quit smoking two days later, and I have been enjoying fresh air, greater taste and an overall feeling of "hell yeah I did it" for almost a year now. My wife also quit one month later thanks to the book. First time an author actually delivers on its premise.

* Nintendo Wii with Wii Fit Plus game and balance board: usage has been on and off, but I still enjoy the combination of exercise with games. Using it for yoga and strength training, even with its limited variety and how it measures things, has meant that it’s a lot better than doing nothing. It’s no home gym though. The Wii Sports Resort game can also make one pant and have a good enough cardio workout.

* Apple Watch: yes, it’s quite easy to cheat and close the activity rings for standing, exercise and calories burned, but it still helps. Not having the phone around to see what a notification is about (and acting on it) is another plus. I can’t wait for sleep monitoring that’s coming in watchOS 7 (to be released in a few months).

Additional mentions: washing machine (for clothes), a powerful blender (like Vitamix), pressure cooker, and a stovetop with four burners.

The original ones were awesome, but these ones are even better. Absolute game changer.

- Crockpot (cook while you work)

- Good mattress (you spend 30%+ of your time there)

- Roomba (clean while you work)

- Ninja blender/food processor

- Noise Canceling air pods

- toaster oven (cheap and you can cook everything)


👤 Raed667
A Garmin watch. Having your health data easily available makes healthy decisions (take the stairs, or walk a bit more, or hit the gym...) a lot easier.

👤 excitednumber
I love stuff like this so here are my contributions:

1 - the economist audio edition. I always found it incredibly exhausting and impossible to keep up on current events in a moderately objective way (nothing is perfect). The economist audio edition ate up all my podcast time but allowed me to feel well informed across various topics. I highly recommend it to anyone who enjoys following geo-politics, economics and other topics. They allow download to mp3 and stream via an app (I use musicolet on Android).

2 - RM Williams Chelsea boots. These are perfect chelsea boots for those who are in the market. I will buy many more pairs in my lifetime. Comfortable from day 1.

3 - a reusable water bottle that brings you Joy for the office or work setting. Drink water!!

Apple Watch Series 5 - I am exercising more than ever.

Intelligent Investor - I read this book around 15 years back and I am at a better place financially, partly due to it.

Road Bike - Bought one around 5 years ago. Best way for me to exercise and feel-the-wind-in-my-face. Finally, wife agreed to get one as well. Now we are riding together. Best feeling.

A Home - It's a double edged sword. Spending tons of time working on lawn and garden. Great way to connect to the roots. On the flip side, it's easy to get sucked into projects and not have time to pursue side projects.

Linux.

*acquired - not purchased.

I've been through many game changing OSes (I'll skip pre-Windows) NT, OS/2 and Windows 3.11, then Win95 and finally - arguably the last decent OS from MS - Windows 7.

Then I discovered Linux (debian and ubuntu flavours mainly) and it's been a game changer! I haven't had an anti-virus clogging up my system nor required running registry cleaners. I feel like I've regained control over my computer vs. it controlling me!


👤 Zanni
Hydro Flask pint glasses. They look great. They're insulated, so they keep your drink cool longer and, even better, you don't have to deal with condensation. They're pleasantly textured for a better grip, and if you do drop them, they don't shatter into dangerous fragments. Much more expensive than glass, but way, way worth it. If price is an issue, I believe there are similar designs from others.

👤 speedgoose
Eyeglasses. It's actually very useful and relaxing to not see the life in blur.

👤 nrp
If you live in a cold climate, a heated mattress pad is a game changer. It lets you sleep more comfortably and also reduce energy use by turning your central heating further down at night. They are pretty ubiquitous in Korea (probably from a legacy of under floor heating and sleeping on mats), but not commonly used in the US. They should be!

👤 frrdinand
A used bicycle for commuting, riding around the city and traveling. It’s a racing bike of the 90s, fast, light and reliable.

👤 aaanotherhnfolk
A small (~4qt) water boiler for the kitchen. Having on-demand hot water makes tea as available as a glass of water.

First benefit: tea is a beverage hobby with some stunning depth (think wine, beer, scotch, etc).

Second benefit: Lots of flavor diversity means you won't have to reach for sugary or alcoholic drinks as often to fight off boredom.


👤 syedmeesamali
Arduino — Makes me happy whenever I look at it and feels like I can build anything with it. iPad — I read all my books there. Without books I don’t know if I exist. Car — A car that I love and makes me feel happy and confident every time I turn the key. It’s patrol safari.

Most pleasure per dollar: My 2008 Jamis Aurora touring bike. I don't get to take it on tours very often, but my local rides are instant euphoria. At the moment I'm sidelined because a new tire is on order...

Most useful small ticket item: a 12" x 18" erasable whiteboard lap desk. I like to do writing in an armchair and this is just perfect. Years ago I went into an educational supply store with my wife. While she was looking for something for the kids, I found the lap board.


👤 SAI_Peregrinus
Sous Vide immersion circulator & vacuum bagger. Extremely versatile, makes cooking things that are hard to get perfect much easier (eg pork), not excessively expensive.

Instant Pot. Similar to above, but for a different set of foods.

Hot air rework station. SO MANY electronics repairs become possible with one of these.

Pet birds. I love them. Definitely not for everyone.

Engagement ring. The ring itself is just a symbol, of course, and the relationship can't be purchased. But it symbolizes a significant moment.

Atari 400 computer in 1980.

More recently 3 pairs of $1 reading glasses from a dollar store. More expensive ones start at 1.25 strength and 1.00 suits me better for computer distance. Will be updating with blue-blocking ones--they feel so relaxing.

LG G6 (and later G8) phone + JVC HA-FXD80 earphones. I had lost interest in music until I got good enough quality to 'feel the vocals'.


👤 tacotime
Reverse Osmosis water filter. It's turned me into a water snob and I never want to go back. It improves the quality of a lot of things that I cook including like coffee and pasta and it automatically/effortlessly improved my hydration because water just tastes good now. I've used Brita filters and the like and they just do not compare.

Yes to the air purifier. People living without them are insane. Also, buying and running an air purifier destroyed my marriage! My wife said she didn't like the sound of it. So I bough a new, super quite one. Then she said she didn't like the "frequency" not the volume of the machine. One day I came home and she had unplugged it and we got into an argument. I told her to please just "shut up" and that was when she attacked and literally tried to kill me. I got away but later she went to the police and told them she had been "assaulted". Nothing happened but she filed for divorce.

I still love the air purifier though!
