How to get the best image performance (Updated 2021)

1️⃣ Use `width` and `height` to prevent layout shift
2️⃣ Lazy-load images as they enter the viewport
3️⃣ Use modern image formats (WebP, AVIF)
4️⃣ Serve correctly sized images using `srcset`
5️⃣ Provide blur-up placeholders

After the 9/11 attacks, airlines and public buildings adopted a flurry of "security" measures, like taking away pen-knives from fliers or requiring visitors to office buildings to be photographed or present a driver's license.

1/

Bruce Schneier's seminal 2003 "Beyond Fear" called these measures: #securitytheater.

Schneier pointed out that these measures would be easy to circumvent, and were thus providing only the comforting appearance of security - not security

Security theater is worse than nothing. Security theater gives people the false impression that their risks have been mitigated, when actually things are just as dangerous.

After al, if you know that danger exists, you can take some steps to mitigate or avoid it.

But if you have the false impression that you've been made safer, you might unwittingly engage in risky behavior.

Like, if you know your car's brakes are flaky, you might nurse the car along to the mechanic at low speed on side-streets.

But if you don't know about the brakes, you're apt to discover their flaws at 75mph on the freeway.

At the moment #POTUS is sitting on a stack of #Trump cards, he's just waiting to unleash a royal flush!
He has court cases that will go to #SCOTUS and thanks to the Texas case, he's now aware how to file them properly under article 3 not 2, so SCOTUS will be forced to listen.

2⃣
#Trump now has the #DNI report. #Barr stepped down and can now be a witness, he did his job. #Durham is special counsel and can prosecute, in any state.
He’s letting civil, criminal and federal courts fail to handle the situation properly so he can use military tribunals.

3⃣
#Trump has ALL the data from the #NSA, the #Kraken supercomputer, the #Alice #supercomputer, and likely many more computers, unknown to us.
He has the dueling electors from 7 state legislatures. He has VP #Pence, as the final arbiter of which ballots to accept.

4⃣
#Trump has the #InsurrectionAct, the #NDAA, the national emergency, the 14th amendment, the 2018 executive order, the 2017 very first EO, the #Patriot Act, the #FISA warrants, the Declassification of everything, people swearing affidavits by the 1000s.

5⃣
#Trump has all the statistical data being analyzed along with the videos, emails, phone calls and bank transfer statements showing the coordination of the #coup d'etat.
He has #RICO and he has the #CrimesAgainstHumanity videos. #Wikileaks just dropped extensive information

OK, more housekeeping ahead of putting this account up on blocks.

#BurnNotice - search for that coming from my account, you'll learn some things about troubles in late 2020.

But this is going to be pretty meta, it's about what goes a #BurnNotice and why.

We've used the #BurnNotice tag in the past to denote an entity that is in need of special attention. That practice dates back to 2011/2012 and lapsed some time ago.

This is a more traditional sort of

Let's put some bounds on this. Those in a #BurnNotice are NOT:

1) people I dislike

2) people I think are competitors in some fashion

3) "feds", whatever you people mean by this undefined term.

4) informants. Got a list of those, too, it's handled differently.

The #BurnNotice is more focused on people who present as if they might be working for Erik

Or maybe they work for Tiger

Lot of chat about instructional coaching. To get it right, don't underestimate the time it takes!

- There has to be a shared vision for effective T&L from the coaches. Keep revisiting this and keep unpicking all the elements so they are able to break them down and explain them.

We used the Evidence Review by @ProfCoe to create some effective teaching habits, using a lot of TLAC techniques and work from @every_lesson. Knowledge and expertise and ability to break this down is vital.

Lots of time then required with coaches to look at lessons and look at highest leverage point. In one training session our coaching team picked out over 30 tweaks in a 5 minute video. Where do you start? Why there? Consistency key. Leads to great debate.

Time needs to be built in. Time for visits, time for coaching sessions, time to practice. SLT need to all understand the process and buy-in and all live it. Putting staff development first is truly exciting and hugely powerful if actioned in the way it is desired.

Teachers/coaches need to have the process modelled for them. Staff need to understand the why behind IC, not just what it is. Worth talking through research on teacher's habitual practice from @mikehobbiss and @DrSamSims.
