1. Learning by Doing
Learning by doing refers to a theory of education expounded by American philosopher John Dewey. It is a hands-on approach to learning, meaning students must interact with their environment in order to adapt and learn. This way of learning sharpen your current skills and knowledge and also helps in gaining new skills that could only be acquired by doing.
Car driving is a perfect example of this, you can read as much as you would like about the theory of driving and the rules, and this is very important, and the more you understand the theory the better you get in the practical part. But you will only be able to drive better by applying this knowledge on the real road. In addition to that, there are some skills and knowledge that will be only gained by actually driving.
Data science is the same as driving. It is very important to have solid theoretical knowledge and to regularly increase them to be able to get better while working on a project. However, you should always apply this theoretical knowledge to projects. By this, you will deepen your understanding of these concepts and Knowledge, have a better point of view of how they work in a real-life, and will also show others that you have strong theoretical knowledge and are able to put them into practice.
There are different types of guided projects. One of them is a guided project for
There are a lot of benefits for it:
It removes the barriers between you and doing projects
Saves you much time thinking about the project and preparing the data.
It allows you to apply the theoretical knowledge without getting distracted by obstacles.
Practical tips that can save your effort and time in the future.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

11. No time to carefully
check all details the
analytics of this kind
of data is completely
different than for
static data.
In static data .csv you can
check if you have missing data
or not, you can visualise all
details and understand the
data but in real time rolling
data it’s completely different.
You have already set up
dashboards to concentrate on
the most important bits. In
Splunk ,you can set up an alert
When you deal with
this kind of data you
don’t concentrate on
Statistics behind it
only choose an
algorithm from a
selection that you
think will the best
meet conditions. With
static data you think
about R^2,
coefficients and so
much more.
12. read code
written by
someone else
modify the
elements for
your own
purpose
Write your
own code
There are languages like R when sometimes much more efficient is to use
package already in the system.
When you set up a loop on millions of data first check if your loops give the
expected output and run smoothly on a smaller data. Once you check that
remember to add loop counter so you can track progress and set up automatic
saving of the output.
14. Lesson 1: relying completely on statistical knowledge without thinking if
correlation does imply causation. (not only regression)
Whatever you can plot it to visualise the data
R, Python, Excel, SAS whatever works for the given purpose – you choose.
Different models for different kind of data
In smaller datasets, static data you may have much bigger fun from an
analytics point of view rather than with rolling in real time data coming from
different sources.

17. If an absent-minded professor takes his umbrella into a classroom, there's a probability of 1/4 that he'll
absent-mindedly leave it there. One day, he sets off with his umbrella, teaches in three classrooms, and

20. Why we may prefer to use Bayesian rather
than Classical approaches to the data?
problem with small n large p
limited influence on what features will be
selected in classical approaches
power of making decision what
coefficients are going into the model or
how strongly they will go into the model.
21. Why we are so different yet
so similar - No two people are exactly alike
and no two people are exactly different
preferences
22. Bayesian statistics allows you to be subjective, to better connect the real world with the data.
P-values and confidence intervals vs posterior distribution. <all outcomes and their probabilities>
Answers that we look for do not match the answers from classical models.
Important question: what is the probability of an event when the p-value is less than 0.005?
A better than B with p-value 0..001. A is more expensive.
You have the predicted probability of quality guarantee in hand., expected prices on the market
Bayesian methods support complex decision – making under uncertainty.
24. Don’t know priors
Are you sure?
