Cool! I did something similar. First I used a bloom filter then a golomb set. https://github.com/terencechow/pwnedpasswords

Lol. I was thinking maybe more don’t send a password to haveibeenpwned and just use your own service?

Would be nice if people from Toronto would enter more data points for the more popular startups I.e. shopify, instacart, unata, ritual, league, top hat, wealthsimple, freshbooks, pivotal, ada, etc

How does this solve problems of data leaks? Let's say some social network uses this Solid framework and you login with your Solid POD. Can't the social network then just save your data into a database? Now when the social network gets hacked millions of personal data is still released into the wild?
What I'd like to see, is every device run a small process which can read the user's data. Html then has a syntax that can be interpreted like
{{ solid://mydata/name }}
{{ solid://mydata/profile.jpg }}
{{ solid://mydata/age }}
etc.
That data is on the user's device encrypted. Apps can never read your data, they can only tell your device to display that data.
That way developers cannot read your data, store them in their own databases, and then accidentally get their own database hacked and we are back to square one.
I'd like the data on your device to be encrypted and have some type of homomorphic encryption such that if an app were to show average age of users, then an app would be able to run some sort of `select average(age) from users` but since the encryption is homomorphic, the app never learns information about any individual user. This would apply for machine learning operations too, so that we could get netflix style recommendations of movies, without a company ever learning what movies we liked, our age, etc.
However, I don't know the first thing about homomorphic encryption so I guess I just have to wait until some great soul builds something like this for us.

Hi Jaros,
Did you receive a response? And if so, how long did you wait after taking the test?

There are no big companies in Toronto that have tech jobs. Google, Facebook, Airbnb, Uber, etc. don't have tech jobs in Toronto. Amazon just started adding tech jobs in Toronto in the past maybe year or two and Shopify is the only exception to this rule.
If any toronto natives know of some big companies in Toronto with tech jobs please prove me wrong.

As a freelancer with clients, are you generally on deadlines? Or is it work when you want? Essentially I would like to work somewhere around 3 days a week but I am not sure that projects would be able to meet deadlines that clients want. In digital agencies I have worked for, I have had to shown work done every week. And the amount of work given to me was such that I had to work the full week. If I were to do that freelancing I would certainly make more money, but I am hoping that there are jobs where deadlines are based on average around 3 days work...

Money flows to everyone, just more goes to those with more money. However that isn't as bad as it sounds. If you own 10% and someone owns 1%, after the money has been given out you will still have 10% and they 1%. From a relative wealth perspective it actually just maintains everyone's position in society, neither benefiting nor disadvantaging anyone...
That's the spiel at least...

> Canada to scrap IBM payroll plan gone awry costing $1B. The Phoenix project was originally chosen by Prime Minister Justin Trudeau’s Conservative predecessors 10 years ago to centralize the government payroll.
Is it me or is this wording terrible?
Trudeau is not a Conservative. It makes it sound like it is Trudeau's party that caused the problem.

Apparently ternary is the 'sweet spot' for computing because it's closer to e (2.7...). We used binary for a while because on / off was the only way we processed stuff but now we have the ability to do ternary with more accurate measures of voltage? Something like that.
Apparently ternary makes math easier in terms of signs etc. as well. The below article explains it better.

Given the wealth of experience with binary though I don't think its prudent to jump to ternary...

> On the benefits side, when you separate your data into groups this way, you can’t rely on your database to join data from different sources or provide transactions and constraints across data groups.
How is it a benefit that you are no longer able to join data in your separate tables? Is this sentence a mistake?
If you are okay with false positives, you can use a bloom filter and tune the number of false positives you want. I chose a false positive rate of 1 in a million so my data structure was still very accurate in determining whether a password was already hacked.
It only took 30 microseconds to determine if a password was in the list and for size, was at the theoretical limit of 22 bits per element or ~1.5gb.
I originally used a bloom filter which made it 2gb but given a bloom filter was just a sequence of 0s and 1s, I was able to use a golomb coding to shrink it down to 1.5gb.
The time to process the original 24gb however, is something that I could have improved, but I kinda lost interest once I already had something that was at the theoretical minimum size, as well as able to determine a password exists within 30 microseconds.
Anyways take a look if you're interested in trying a different approach: https://github.com/terencechow/PwnedPasswords
