NFC watch strap - embedding NFC chip into dumb watch wrist strap
3 years ago • alex
Has anyone tried to embed an NFC chip like MiFare DESFire or even simple NFC tag into a dumb watch strap? Then you could potentially unlock office doors with your dumb watch - should be a bit easier / faster compared to pulling out your thick wallet with Access Cards in it, and it could have potentially some other applications too.

Monitoring ALL Bitcoin Blockchain transactions in real time on a global scale
2 years ago • alex@qrid
We need to monitor / intercept / inspect all bitcoin transactions that are being sent to certain rather small but ever changing list of Bitcoin addresses. Basically, we just need to run a custom code in the event of any new transaction being sent through Bitcoin P2P Network. What would be a reasonable technical approach to accomplish that task? Thanks!

3 years ago • alex
How to disable SQL script compile time errors in VS 2013 while trying to build solution that includes "SQL Server Database Project"?

How would you count occurrences of a string within a string?
3 years ago • kojemyakin
I am doing something where I realised I wanted to count how many /s I could find in a string, and then it struck me, that there were about several ways to do it, but couldn't decide on what the best (or easiest) was. At the moment I'm going with something like: string source = "/once/upon/a/time/"; int count = source.Length - source.Replace("/", "").Length; But I don't like it at all, any takers?

3 years ago • alex
We have some custom MVC controller that dynamically loads different views with view name being specified through action parameter. It was working fine. Now we are going through a website localization project translating most of our UI to another language.

How to select a random row from a table in MySQL?
3 years ago • alex
Let's say I have a table with an integer column called ID being a primary key. It is unique and not-null, but we cannot guarantee it being sequential without gaps. I.e. we may have rows with ID = 1,2,6,7,8 and we do not have rows with ID 3,4,5 etc etc. This is why we cannot just generate a random number and get a row with that corresponding ID. Also we want all rows to have equal chance of being selected, so b/c of the gaps in ID values we ca ...
