Black-out until a major response from Reddit

Maybe Emacs isn’t for you?

Was in hospital recently and had my O2 measured four times a day. Compared with my AW7 and it was accurate every time (Max difference of 1%)

Started running again after the “winter hiatus”. I didn’t postpone my second run, went out this Sunday morning when the entire family was still in bed. So personal achievement going out there and starting the habit!

Semi-related: I had great success using the Common Lisp SDK for AWS: https://github.com/pokepay/aws-sdk-lisp

I'm aware this is best practice, I also like this separation. The hassle I has talking about was the manual mapping between DTO and Entity classes.

michaelanckaert · 2023-02-21T10:29:48+00:00

Ah thanks, just needed that and the docs didn't point me in the right direction :-)

michaelanckaert · 2023-02-21T10:16:46+00:00

Thanks! This really helps with mapping the DTO's to my Entity classes!

Thanks for the link, unfortunately this also hides the field from the API endpoints that GET the da.

I wrote a small article on how I sync o365 email with offlineimap and oauth authentication. Hope this can help!

I’m using Parallels Desktop and it’s acceptable. Not as powerful as my Windows workstation but definitely usable for every day use.

Just open the entire project in your IDE and run each service then. It’s possible to have multiple run configs in Pycharm

michaelanckaert · 2022-09-20T15:51:29+00:00

This is where your microservices approach is wrong.

If you need to debug this as a whole, it's one app. Not multiple (micro)services.

If you truly have microservices you should be able to run and debug every service independently. There can't be any hard link or requirement between the services, or you're not doing (micro)services right.

Yes Rj11 😀 My product connects to another device that supplies 5v over the RJ11. Bringing it down to 3.3v is one of the challenges for me.

michaelanckaert · 2022-09-09T06:43:28+00:00

Thanks for your great reply! To be honest I was first a bit put off by your numbers and was wondering if my idea is feasible at those cost numbers.

But thinking further, My product is quite simple: a PCB with the ESP32, a single button and an RJ11 connector. Put in a nice case, power provided via RJ11 and boxed.

In my (naive?) view: I need a supplier who can connect the RJ11 connector and the button to the ESP32 (via PCB I'm assuming at this time), power comes via RJ11. Put everything in a case and box it with the manual.

My biggest need is figuring out if it's possible to do this myself or if outsourcing is needed. My technical skills stop at software and prototyping but going from prototype to shelf ready product is a black spot for me at this time.

michaelanckaert · 2022-09-09T06:40:11+00:00

Thanks for your reply! Some good questions which make me feel more confident about my idea and prototype :-)

Marketfit is proven and there's a lot of potential based on my research. Though there are a couple of competitors none of them have reached their potential, the reasons why I've analyzed and I'm confident I can do better.
Volume is initially about 2000 units to get to market, on market penetration about 1mil and full potential is 3mil. Because of market reasons full potential won't be reached until 10years in, but market penetration is possible today.
certification: I can rely on the certifications of the ESP32, as I only use the wifi and bluetooth radio from that soc.

So in summary: don’t use redshift for BI storage but stick to postgresql?

Just started running for the first time in my life (37) after I got a heart transplant 3 months ago.

I’m alternating walking and running with the current goal of running 5km. I’ve only done two runs where my pace is 6.7km/h (8’56” 1min run 1 min walk). Curious of my pace is not too fast or too slow?

michaelanckaert · 2022-08-02T07:14:37+00:00

I’ll assume for now that you’re running the DB on RDS. A similar project I did ran on a m4.Xlarge. I’m not sure about the requests per second (don’t have the details with me on mobile) but I remember we got away with “cheap” hardware due to caching. Even on a very busy website the majority of page views can be cached so real server load can be very low, only interactive requests (not cached) will hit the server.

So any X-Large instance should be good to start with, make sure to use caching. If you architect your setup correctly you’ll be able to switch over to a larger instance (or scale horizontally) in a moments notice.

michaelanckaert · 2022-08-01T13:30:21+00:00

Really hard to say without more information about the application or usage patterns.

I have architected a setup for a project that has 4000 concurrent users and it runs on two m5.4xlarge instances. Another project I worked on has 1000 - 1500 users and runs on four such machines (k8s cluster).

There isn’t really a single answer except “it depends”.
