On granularity of tests focused on behaviour.

🧵1/22
A function is one of the smallest units of behaviour. Given an input, it returns the output.

This means that given the context (input), the function's behaviour can be verified by calling the function and looking at the outcome (output).

🧵2/22 Pure function
Notice that the most straightforward outcome to verify is the function's return value, but it's not the only outcome we can look for. Functions can have side effects, modify state, interact with collaborators, etc.

What is CI/CD?

Continuous integration (CI) and continuous delivery (CD) are two approaches to software development that are designed to improve code quality and enable rapid delivery and deployment of code.

#DevOps #CICD #Cloud #Agile #Testing #Cloud #Linux #Security #ITjobs
A modern CI/CD pipeline in DevOps has build, test, and deploy stages-and aims to automate as many of the processes within these stages as possible.

1. Source Code: Changes to source code can trigger CI/CD tools to initiate the pipeline, or the CI/CD pipeline may be triggered
by automated scheduled work sessions or user-initiated workflows.
2. Build: The new code changes to applications are created and compiled to be prepared for the testing phase.

3. Testing: Testing automation via CI can save developers tremendous time and effort.

Debunk on the #pfizerdocuments . They mean nothing. I’ll tell you why. But first here is the link to the original paper:
phmpt.org/wp-content/upl…
If you read them, You will find 42.086 #notifications concerning possible side-effects and a checklist of possible adverse-effects which #Pfizer looks for in the trials (starts page 30)
These adverse-effects are different then side-effects. They haven’t happened, are only mentioned as things to look out for and prove that #Pfizer is thorough in their #testing and #research.

"I'm really really good at #debugging" a #sap #abap developer friend once said to me. I replied "oh thats awful". Why? Because it means he spent a lot of time finding bugs in code that was probably not covered by tests. But how do you debug efficiently? (1)
Many people use breaks points, watchpoints, breakpoints on messages, exceptions, post mortems, job debugging, etc and are successful that way. But at some point you have to "look at code". Over the years I've seen a few repeating patterns: (2)
"Just go for it". Is the error reproducible at all? Before debugging, it is better to check that, otherwise you lose a lot of time with code in which the error is not / only difficult to see by debugging. Because everything works as it should durching your debugging session. (3)

I want to start out by saying, you folks are in a tough position, being PUBLIC SERVANTS of WE the People. I would like to believe that you truly have the best interest of our children and the community in mind, but you are factually acting outside of your delegated authority...
by practicing medicine, imposing unlawful medical interventions, and by simulating legal process.
That being said, our forefathers put together one of the most powerful and amazing documents in our history. The #constitution, which was drafted to protect individual rights!
They did this in an effort to make sure we didn’t end up under #tyranny again, and yet, here we are with individuals and Agencies operating outside of both their delegated authority and outside of the law. I’d bet my LIFE (emphasis added), if any one of them were alive today...

"End of any freedom with covid has now been stolen for the vulnerable."

"The mental health of my children going to school will now spiral downwards uncontrollably."

🧵SCIENTISTS ADMIT MASS COVID-19 TESTING ARGUMENT RESTS ON A “HYPOTHESIS”🦠💥

With their influence waning, @IndependentSage has rebuked Gov plans to end “free” COVID-19 tests— urging the “immediate” publication of scientific evidence.

So, what is their own evidence? Read more👇🏻
So, for background, who exactly are Independent Sage?

They say they are a “group of scientists who are working together to provide independent scientific advice to the UK government and public on how to minimise deaths and support Britain’s recovery from the COVID-19 crisis.”
Prominent members include:
•Prof Susan Michie
•Prof Christina Pagel
•Prof Gabriel Scally
•Dr Zubaida Haque
•Dr Kit Yates

All of whom have been plastered over our television screens, airwaves, & newspapers since the pandemic began.

It’s not the first time I’ve featured them

#Arlington #COVID19 #Cases

😡: Almost no students who are exposed are being told directly of exposures or quarantined.

We encourage parents w/COVID+ kids to DIY your own reporting to parents and families where you can; assume APS isn't going to notify exposed. It's up to you. Image
#Arlington #COVID19 #Cases

The worst school, with >13% of its students catching COVID in Jan, is #Montessori Public School.

MPSA was found to be one of the worst schools for ventilation + parents reported a lack of implementation for outdoor lunch in Jan. for some classes. ImageImage
#Arlington #COVID19 #Cases

So far, YTD, two dozen Arlington public schools have had more than 10% of their student body test positive for COVID-19.

In such an environment, removing masks when community transmission is so high seems like the ultimate folly. Image

I felt terribly sick on Saturday. Sore throat, flu symptoms, heavy head. My rapid test is negative. All my friends have #COVID19. Literally everyone. 349 cases in my kids school last week.Overcrowded and zero #ventilation. Sick teachers & sick kids. @ScholaEuropaea @JHahnEU

Friends, I have #COVID as does my entire family. I've put together this list of helpful strategies that have helped me through the other side, though the rest of my family is still symptomatic. A 🧵!

👇
The most important thing you can do is panic about whether or not your unvaccinated child under 5 will have lasting chronic issues from this virus. I've done a lot of this lately! It's *really* important, because apparently no one has done this, you fucking assholes @cdc

/1
Secondly, make sure you're #vaxxed and #boosted. Wait, you have a child under five? Then just circle back to point 1 and wear down your own immune system by panic-googling symptoms for your kid's specific health problems BEFORE getting a disease known to cause brain damage!

#GoldreichTestableCodesSurvey-2
"Abstract
We survey known results regarding locally testable codes and locally testable proofs (known as PCPs), with emphasis on the length of these constructs. Local testability refers to approximately testing large objects based on a very small

This yields super-fast approximate #testing of the corresponding property (ie., be a codeword or a valid proof).
We also review the related concept of local decodable [recte 'locally decodable'

The survey consists of two independent (i.e., self-contained) parts that cover the same material at different levels of rigor and detail. Still, in spite of the repetitions, there may be a benefit in reading both parts.

FYI: even with mild #covid people still have to stay home from work/school! This is why schools are closing & businesses scaling back- WE DONT HAVE ENOUGH PEOPLE RESOURCES! Even with #mitigation/#vaccination mass infection isn’t the answer- we want lower RATES of infection
The calls for uncoupling infections & hospitalizations are necessary as we will be living with #COVID19 forever- BUT RIGHT NOW THERE IS A LOT OF CIRCULATING #VIRUS! To address THIS issue we need everyone to use all mitigation measures: #masking, #testing, #stayhome if sick.
Reading piece after piece about why we can’t close schools & how we want no #masks are premature! No one wants to shut it down. But we need tools AT SCALE. That means counties & states need massive influx of #masks & #tests& people to administer tests, #contacttracers too

Almost impossible to get a PCR test in #Westchester (or NYC) right now. This evening on FB, the County Executive, George Latimer, provided an update on the #COVID testing situation in Westchester County. See below for content: 1/12
"Update on #COVID #Testing & more…We’re all well aware of the long lines faced by those who want/need COVID testing. This post will update what is being done about it.Two things have worked to push more people to get tested:more infection exposures; #holidayseason #travel 2/12
The ability to satisfy this demand has been compromised by insufficient number of test kits, and staffing gaps in the health care field.We’ve seen an explosion in #COVID cases the last week - 2,000+ new cases in less than a week. A surge we haven’t seen in a year. 3/12

🤶Dear Santa: Please, we need some Public Private Partnerships in ##Westchester for Christmas and the Covid Surge! Can you transfer some #privatesector elves to help @westchestergov provide free, accessible (by mass-transit and by drive through) rapid #PCR #testing Also, 1/6
🎅for stocking stuffers, how about enough seven-piece packages of rapid #antigen #testing for home use, available by mail or at local #health departments or local houses of worship or even by #reindeer for every #Westchester resident, free, upon request? Also, 2/6
🎅maybe Mrs. Claus can come on down to speed up our county health department to get #TestToStay rolling in our 40 #publicschool districts? It's been too much talk and no action. Finally, just want you to know, 3/6

Very important read about the fate of those who refuse to participate in the world debt reset program, healthpass or the vaccination schedule: "Indefinitely" in isolation until one complies and having "all their assets seized" Image
You can see how they are tracking the progress of their agenda on the lower left corner of the document. Image

So twitter's spam protection kicked in and I can not answer all the people who contacted me about #TestingTheMerge, so I need to publish the message I'm sending everyone here:
Hey,
Great that you're interested in joining the testing efforts.
I'm a bit overwhelmed with the amount of responses I got, so I'm currently thinking about how to onboard so many new people to get them started as smoothly as possible.
I'll try to create three different classes of tasks; for users/non-technical testers, for technical testing and for testers that are very familiar with the inner workings of ethereum.

🔴Excellent 🧵 again from @trvrb👏

#OmicronVariant really seems weird, interesting and terrifying. #OpenData #OpenScience will save the world now. Global cooperation and openness. This is no time for ’normal’ greed (nationalism, 💉patents), as the globe and future are shared. 1/
What we can already say is that the world must be grateful to #SouthAfrica🇿🇦 #Botswana🇧🇼 @Tuliodna @ceri_news @nicd_sa, all experienced with #Sequencing (HIV, BetaVariant): THANK_YOU🌼.

Thank you for the quick #Omicron discovery and global alert. Thank you for your honesty.

Like #China🇨🇳 in 2020, have 🇿🇦🇧🇼 been now extremely fast & open online, working by the principles of #OpenScience #OpenData. China solved in a week the #SARSCoV2 gen code publishing results online — allowing #US🇺🇸 to start vaccine development next week. 3/ mobile.reuters.com/article/amp/id… Image
