maddynator··on Ask HN: Most interesting tech you built for just yourself?
Sweet. I thought there was a way to dm on HN.

Your profile has your website which has your email. I will email you.

Thanks

maddynator··on Ask HN: Most interesting tech you built for just yourself?
Thanks for sharing.. definitely will check it out
maddynator··on Ask HN: Most interesting tech you built for just yourself?
I’ve built a mac app that has all the dev tools I use on daily basis. Its 100% local & 100% offline. I was worried pasting company specific data on public website tools like JSON formatter, SQL Formatter etc and also hate having too many single trick pony apps.

So one app to rule them all. Current list of tools in the app are: - Todo list integrated with Pomodoro timer - Notes with ability to be converted to todo list - Pomodoro timer - JSON/SQL/XML/YAML/Protobuf formatter and error detector. - Converter from JSON to CSV and other formats. - Meditation/Gratitude general - Universal time clocks - Count down timer, focus timer, stopwatch

In development: - Unix time formatter - CloudWatch metrics reader (to monitor my other cloud apps) - S3 explorer (My own infinite cloud storage with no one reading meta-data or scanning my pictures/documents) - Cron explorer and scheduler

In process of putting it on app store. If anyone is interested in trying, DM me.

Any paper to understand the technique behind the breathing exercises??
maddynator··on Apple fined $8.5M for illegally collecting iPhone owners' data for ads
lol that’s like saying the fine for speeding is $.2
maddynator··on Ask HN: What companies will file bankruptcies in 2023?
lol... But I definitely see it... they offer solar at 50-70% higher price and justification is "We provide better service than Tesla"

I have talked to 3-5 different representative at costco and directly.. not sure how they are still in business

maddynator··on Ask HN: What companies will file bankruptcies in 2023?
Interesting.... is there a way to know which startups didnt get the funding? I can see carvana.
maddynator··on Show HN: Open source data discovery and observability platform
Thanks folks. How do i contribute to the project?
maddynator··on An account was suspended
Yeah completely matches my experience. Twitter banned my account for far less and unlike Ben, I dont have major presence or large audience. I wrote about my experience on the blog [0] so others can learn but what I learned is that there is an automated system to flag and automated system to respond to your questions and the later system rejects 99.99% of cases. You have to be in Ben's position to fall into that .01%

maddynator··on Ask HN: Have you experienced “hiring fraud?”
Yep had the same experience multiple times in tech industry especially when hiring via contracting companies.

I asked around and while what you encountered is one way they cheat, there are many ways the do it. I collected all possible ways candidates cheat and redflags to look out for when interviewing candidates in my blog post.

maddynator··on Show HN: Superblocks – IDE for Internal Apps, APIs and Cron Jobs
beautiful. Looks really great!!
maddynator··on Ask HN: What is best way to do hands-on practice for system design?
I know you didn’t ask for this but Me and couple of my friends at big tech who have given and taken 500+ interviews, do mock interviews for each other and references.

For reference we do paid 45 mins mock interviews. In case you are interested, dm me and I can share more details.

maddynator··on Ask HN: What is best way to do hands-on practice for system design?
I would advise against it. Two reasons: - if the person interviewing you know the specific tech you picked, you give them an opening to control the interview. They can go anywhere they want and you would likely fall short unless you know the stack in&out

- when you pick specific technology, you also have to defend why this one specifically. For ex, why redis and not memcache or why only postgres and not redshift..

If you keep it at sql and no-sql, you can easily defend the answer and control the interview

maddynator··on Uber Eats Nationwide Shipping
This could be a ploy to make stuff in local cloud kitchen, charge for cross country shipping and delivering locally cooked stale food.

IDK, I seems to have a pessimistic view of it at the moment

maddynator··on Adapting to Endure – Sequoia Capital [pdf]
This is same deck that they had in 2008. That said, it’s still applicable

maddynator··on Air-purifying headphones with active noise cancelling
They are definitely not what we are use to when we hear the word headphone but I think they have a specific usecase and market they can address.

I think they are good for anyone doing woodworking, gardening (have pollens), labs where they are chemicals, and similar outdoor work environment.

The problem can be the cost. Dyson are not cheap so and they market that can use is not going to spend that much money.

but the concept is neat. Pushing a boundary

maddynator··on But life had other plans
Got damn. I was so scared to finish the article. Glad i pushed through it
maddynator··on ThriftBooks’s use of supply chain automation (2020)
They are my go to store for physicals books.TB is where my book wishlist is and they notify if book is not in stock and comes back to stock.

The best part is, I have received 3-4 books signed by authors… they were the gift copies to someone but knowing that the specific physical book was signed by author makes it more special

maddynator··on Regulators Shut Down Lending Platform (YC Alum) LendUp
Can someone share how is then any different from another company like Affirm? They are a public company and this seems very similar to them at high-level
maddynator··on Ask HN: What HN threads most influenced your thinking about startups?
Yeah a link to that would be great
maddynator··on AirCover by Airbnb
Wouldn’t you have to have a guest rent it out via airbnb to be eligible?
maddynator··on A terrible schema from a clueless programmer
One thing that worth taking into consideration is that this happened in 2002. When the databases were not in cloud, the ops was done by dba’s and key prefix compression thats omnipresent today was likely not that common or potentially not even implemented/available.

But i don’t think the point of the post is whats right/wrong way of doing it. The point as mentioned by few here is that programmers makes mistakes. They are costly and will be costly if in tech industry, we continue to boot experienced engineers… the tacit knowledge those engineers have gained wi ll not be passed on and this means more people have to figure things out by themselves

maddynator··on How to Catch a Cheating Candidate in an Interview
yeah but thats going to be the case when the accomplice is a close fried... my experience here is about the contractors from contracting companies... they put people in position and move on to next contractor. they don't have time to help the one they placed... it may take a while for the incompetent contractor to get fired and then contracting company to replace them.. Which they will do ...
maddynator··on How to Catch a Cheating Candidate in an Interview
ahh.. may be your lucky.. would you say the same is true for contracting companies from outside USA?
maddynator··on Ask HN: What problem are you close to solving and how can we help?
Trying to find line item based medical bills and laws that govern what information can patients obtain about medical procedure pre and post procedures.

Goal is to bring transparency to medical bills and remove the unknown.

maddynator··on Staff Engineer Guide
So as a staff eng you will have projects that you are leading but have cross team/org dependencies.

You have to get alignment with those teams and get projects on their roadmap/sprints so you can get unblocked.

But a lot of engineers think they can just ask cross-functional teams fit with but get surprised when things don’t happen. And that’s because other team is busy and not idling.

As a staff engineer you have to figure out how you can contribute to cross-team such that they agree to the problem, let you contribute to their code base, and help them unlock you.

Its a lot of championing and relationships building that is expected at staff level.

I hope that is useful

maddynator··on Ask HN: Tools you have made for yourself?
I created bunch of scripts that allows me to spin up a full 3 node mongo server with interfaces and webui. Creates daemons to monitor everything and restart when crashing, auto-renews certificate for lets-encypt and spins up a json server with basic crud apis ... starting a new project takes 30 mins but it saves me sooo much time debugging why things are not coming up as i wanted
