I have distracted myself this week with the extraordinarily mundane task of designing a sample identifier scheme. I want to share some decisions I made in the hope that it saves somebody else some time.
The first choice was the alphabet. I wanted to use human friendly, familiar ASCII characters, but intentionally leave out potentially confusing characters. I'd previously read about "Crockford's base32" (https://t.co/xa3WREc1RQ) which tries to address this problem.
But my search led me instead to z-base32 (https://t.co/5PlTgAgyDU). The z-base32 alphabet is shuffled to try and make encoded identifiers easier to discern. I don't actually need the encoding, but I liked the idea that this shuffle makes sequential identifiers less sequential.
z-base32 takes the interesting choice of using the letters in lowercase to help identifiers form "coastlines" that aid with human recognition. The lab quickly fed back they didn't like this, so I force the alphabet back to uppercase.
With the alphabet decided, I wanted to pick a checking scheme. I learned that each algorithm catches different types of errors, so one needs some knowledge of how the identifiers will be used when making a decision.

Ok #ygk, I have a serious thread coming to end this series.
Part 3 of 3 focuses on what happens to people after they turn away from the church.
Most said they were shunned, excommunicated, and defamed by their former friends, even by some of their family members when they left.
In part 1, I described how peopleâs whole lives played out at the church.

After leaving, they had to relearn how to live.
They never listened âsecularâ music or watched certain movies, some were even told to boycott Starbucks, because it supports Pride
Going back into the "real world" made one former member feel like she was "losing her mind."
Also, part 3 shows the extreme fear that some people had after leaving.
One person said she worried she would literally be struck by lighting if she spoke badly about the church. #ygk

Former members of a #ygk church say its leader, known as "Apostle,\u201d promised them miracles, but instead they were traumatized.

As faith communities like these grow, the former members are calling for oversight of independent, charismatic churches.https://t.co/eVnG52dBcm

At this point, the countries with most genomic data to analyze spread of the variant virus belonging to https://t.co/ImaHU6Jxdv B.1.1.7 lineage or @nextstrain clade 20I/501Y.V1 are the UK, Denmark and the USA. Here I compare growth rates of B.1.17 across these countries. 1/13
Working from @GISAID data, the UK has 18776 genomes, Denmark has 6089 genomes and the USA has 3093 genomes from specimens collected after Dec 15, 2020. Here, I'm looking at daily genomes with collection dates up to Jan 6 that were not pre-screened by "S dropout". 2/13
For the UK, we can see a steady increase in the frequency of sequenced variant viruses belonging to the B.1.1.7 lineage, reaching ~70% frequency at the end of December. Solid line is a 7 day sliding window average. 3/13
We can fit a logistic growth model to the frequency of B.1.1.7 in the UK data to estimate the rate of frequency increase through time. 4/13
And following @erikmvolz et al (https://t.co/l2ElhJVk8b) we can convert from a measured frequency growth rate to an estimate of increased transmissibility by assuming a particular generation time, which I take to be between 5 days and 6.5 days. 5/13

But you couldn't pay for the Jobs I did for you.
Celebrities and this public showcasing of being nice.
You and your brand are evil!
I know this might not even blow up cos I have very little followers but I will just call on few sensible people I've noticed on here @SMiTHiE___ @Shawnifee @SavvyRinu. Your retweets would go a long way into creating awareness of hoe some of these so called celebrities are evil.
August last year, I messaged Lilo on Twitter here trying to secure a graphic designer Job on her team cos I really saw she lacked that and needed one. Fastfoward, she replied and told me to send my portfolio to her mail which I did.
I knew she was going to be really busy...
Cos it was just like few weeks after she left the house. She responded after a week or so and I started talking to someone on her team and she told me they'd just want to try me cos they have so many other people trying to secure that position on the team so they gave me a test..
They told me to make a design of a brand she's working on launching which I did and Lilo really liked it and approved it.
I was really excited as I'm just a student and just trying to make money for myself, I put into so much effort designing just trying to secure a spot....

Order it! I\u2019ll pay for you.
