Been playing drums for 30+ years. I ended up with tinnitus after an extremely loud concert wearing Hearos, which are a brand name for Etymotic ER20s (as with all things hearing it probably was not just that concert, but that was the single point at which tinnitus started and didn't go away). After that I decided to just spend big and buy custom molded ear plugs (In my case 64audio). Even when wearing the -20db cartridges they were significantly more effective for me than the ER20s. My theory is the shape of my ear canal makes it hard to get straight plugs in to get full protection (even the foamies I can't get in far enough). Over time I have gotten used to the tinnitus and with the use of IEMs and the custom Ear plugs, which I've been using for 10 years now, my hearing hasn't gotten worse and the tinnitus levels have remained low.

Not going to speak to the article but want to layout that in 1997 when I was a waiter at Chili’s I made $2.50 an hour base wage, but with tips nearly always cleared $24/h. In 1999 I was a waiter for an upscale steakhouse in the city of Chicago and on average made about $40/h. Several of the waiters there were career waiters and had families. Many career waiters worked very hard to get jobs at higher and higher end restaurants and could clear 100K on the year back in 1999.

This is avoidable by continuing to use Ruby. Just continue to use it and contribute to the community, it's that easy. Ruby still has big businesses using it - Github, Airbnb, Shopify. There is no reason to believe it'll go the way of cold fusion. The language ecosystem is much different than 20 years ago. There are so many languages all thriving. Even Perl is relatively healthy and is a fine choice for doing many things in the software space.

My hypothesis: it’s hard to have a descent grasp of technologies without having actually used it. Tie that with “let’s not include too many moving parts” and it’s easy to end up in a situation where the edict is “Kafka”. Let’s say you have never used RDBMS, only used rethinkdb and that turned out to be problematic for whatever reason, next project the founder hires you on the premise that the system you build needs to scale to billions of requests per minute ASAP (eventhough currently there is 0 traffic).

I worked at a pizza place in the early to mid 90s in the suburbs of Chicago. The place ran its own delivery service. The service was fantastic, pizzas delivered piping hot most of the times. It wasn’t very hard for the restaurant to set up and operate the service. 15 year old me understood it pretty well.

That said I think where these delivery services have come in is at places that historically didn’t have their own delivery. Now these places suddenly have “delivery as a service” to add on with Seemingly no additional work, a fee, and additional revenue.

These places could easily start their own delivery service if they want, but they must still think it’s easier to pay the delivery as a service fees.

I emailed a local comic shop that’s closed to the public, but I was able to order $100 worth of trade paperbacks. Got it 2 days later. No “online” shop, but still worked. As best you can, try to spend money with the local stores you used to go to.

I worked for Ticketmaster back in the early 2000s and helped build an auction platform for them. Some artists did use it for the highest quality seats, and a few even did it for the entire venue, but many artists were afraid of it because they felt like they would then be the responsible party for 'squeezing' their fans. Perhaps the idea that they would get the money along with other people running the event, as opposed to scalpers didn't resonate. I wasn't around when the platform was decommissioned so I can't say for sure all the factors at play but, for sure many artists didn't like the idea.

I'm a CTO at a YC grad Care Revolutions. There's a lot of comments on what kind of work environment is bad. What do y'all suggest a startup with limited resources do to be an incredible place to work for while also being a highly productive environment? I'm especially interested in suggestions as it relates to your health both physically and mentally!

While I'd agree with you as an entry level candidate, with experienced people, I've found the language is often the most important thing on the list. Often above salary. I would say it is more commonly number one than any other factor. I only know of a few programmers who have shifted through more than 2 languages in their careers (20+ year type careers). I don't have brilliant insight as to why. Perhaps the fear of starting at ground zero? Imposter syndrome? Feeling of throwing your past experience down the drain?

I think being called out for a bad habit is a step in the direction of replacing/improving it. In some cases it’s enough and the person caught figures out a better habit themselves. In other cases more techniques/actions are necessary. As it relates to this article the context was nicely set to illustrate the jar technique. Other contexts would need to be set to illustrate techniques related to situations where calling out is not enough.

I often institute a “just” $1 jar. Anytime “why don’t we just” or “it’s just” is uttered you have to put a dollar into the jar. This applies to engineers, managers, myself, everyone. The idea is breaking the habit of trivializing work that isn’t. Something like a dollar jar is fairly effective as a notifier but doesn’t necessarily replace the habit with a better one. Nevertheless the game itself seems to help even if dollars aren’t transferred into the jar.

The problem is squashed salaries. I’ll have junior devs or people straight out of code school asking for 75-80% the salary of a solid senior dev. If I have to make a bet on who will be easier to manage and get productive 4 seniors vs 5 juniors for the same total expenditure I’ll choose the seniors every time. Even at 2 to 1 I’m taking seniors. Maybe around 3 or 4 to 1 juniors might look better. But that means junior starting salaries around 50k which no one is taking. Salary range is too squashed in the industy.

The Etymotic earplugs are the same thing as Heroes. For me they don't fit well and thus don't reduce the sound levels as much as designed. For some people they probably work well enough, depends on the shape of your ear canal, where it bends and to what extent. You can get custom in ear plugs for $200 including the molding process (though a bit tough - you have to wait for sales).

I was in Kauai about 10 years back and a friend of ours who hunts goats traded with a friend for some fresh of the boat tuna. We tried a bit of that tuna the first day, maybe 8 hours after it was caught, sashimi style. It was terrible, just as our friend told us it'd be. It was super chewy and tough. Next night the stuff was great, and two nights later it was FANTASTIC!

I've been in favor of up/down for years over x out of 5 or x out of 10. The core reasoning is: it captures your overall emotional response to something very succinctly. Sure you might hate X more than Y or like A more than you like B, but you'll return, revisit, recommend all the things you like and not do so for the things you don't like. When you can rate out of 5 or 10 you get thrown into a sort of tizzy trying to rationalize a system of what is 1 star, 2 stars, etc. Do you subtract a star because you think something is overpriced even though you like it? Do you subtract a star because it's hard to get it (say slow delivery) even though you like it? Basically you want to start to categorize every facet of a product/service which becomes complicated quickly. Thumbs up/down avoids all that and I think over many hundreds or thousands of reviews the ratio of up to down will provide a good probability indicator of liking something or not.
