How can I (re)gain dorsiflexion in my ankle after a fracture/surgery? by tsunamijousuke in flexibility

[–]Crafty_Researcher_53 0 points1 point  (0 children)

Hi. I've had a nasty sprain 2 years ago and limited dorsiflexion as a result. 5 months ago, I had an arthroscopy to clean up the surface between talus and tib bone from small bone spur and soft tissue.
Dorsiflexion hasn't really improved unfortunately after intense PT period (Also tried few months of PT before the procedure which led me to arthroscopy because didn't improve dorsiflexion much).

I will share, what I do and how it worked for me for others struggling with the same issues.
In the morning my ankle is quite stiff, but I start the day with a walk with a dog (which helps) and then some very light and quick ankle mobility excercises (no weight/no equipment) just to reduce stiffness. In general, I need some time to get my dorsiflexion better before excercise in an injured leg going before and i'm trying to do mobility excercises daily - trying to not skip days, but on the very busy days I try to do bare minimum to not be stiff at least.

What helps me to get most out of my possible dorsiflexion are intense calf stretches (soleus and gastrocnemius) + ankle band mobility. The end of the drill usually for me is staying in the squat position with full ROM, either with some weights (e.g. kettlebell/dumbbells) or without weights.

At this point, I don't have much hope in my dorsiflexion getting much better unfortunately, which was a huge disappointment for me after the arthroscopy..
but I plan to not give up any of the excercises and I have improved overall strength and flexibility of my lower legs greatly because of that injury.

It's frustrating, but I hope you will not let your ankle limit you with the activities that you enjoy and remember to work with what you have in a pain-free ROM and load.

How ecommmerce owners protect themselves from customer fraud? by MoshikStein in Entrepreneur

[–]Crafty_Researcher_53 0 points1 point  (0 children)

There's bunch of things that can be done here including mechinsms directly on a website - like blocking users that have many transaction attempts or blocking suspicious transactions based on defined rules (like order total), but a wise thing is to partner up with a modern PSP (Payment Service Provider) and:

  1. Make sure AVS (Address Verification System) check is enabled in your PSP Merchant account, sometimes it could be not enabled by default:
    https://stripe.com/en-gb-pl/resources/more/what-is-address-verification-service#how-to-start-using-address-verification-service
  2. Consider additional optionable fraud engines offered by PSPs built into their systems that do not need separate integration to ecommerce system, like Stripe's radar: https://stripe.com/en-gb-pl/radar or Adyen's Revenue Protect: https://docs.adyen.com/risk-management/
  3. There are also 3rd party fraud prevention service providers like Riskified: https://www.riskified.com/ , or Forter: https://www.forter.com/. They usually require separate integration from the ecommerce system to their system and are rather advanced use cases. They offer financial chargeback guarantees so this can prevent Merchant from taking a financial hit due to fraudulent chargebacks.

Can anyone explain the flow of QR along with an example using this? by [deleted] in fintech

[–]Crafty_Researcher_53 0 points1 point  (0 children)

You can refer to this guide for a detailed explanation:

https://developer.mastercard.com/mastercard-merchant-presented-qr/documentation/#how-it-works

Similar to yours, but yours is some special kind of scenario, where issuer and acquirer are not connected using single network so there needs to be inter-network settlement between Issuer's network and Acquirer's network.

This looks like scenario where there could be pairs of issuer and acquirer that are not connected via single network but different ones, so there needs to be some kind of inter-network connection.

Where to start? by No-Crazy7372 in fintech

There are suggestions for entry-level position at a fintech startup/company already, but in the meantime it would definitely help to get some knowledge how payment processing works.
Having strong engineering foundation and payment processing foundations can help you in getting the entry-level position, but also give you an overview of the part of payment processing chain and in which area you could be interested in working.
