Porting vanilla (minimal external API usage, no SIMD, no threading) C++ code to work in the browser with emscripten and WebAssembly is amazingly simple now. The Emscripten docs are excellent, but here are some things that could speed up the process of getting started:

 1. Beware of code which does unaligned memory reads/writes (which "may be slow on some CPU architectures")
2. Test with -fsanitize=undefined -fsanitize=address
3. Link with "-s ALLOW_MEMORY_GROWTH=1" and "-s INITIAL_MEMORY=X", X is a multiple of 64k, allows the C++ heap to grow.
(I completely avoid unaligned memory reads/writes because when compiled to asm.js they "can fail silently".)
4. Link with "-s MALLOC=emmalloc" to reduce compiled size.
5. I usually test with -O1 because -O0 can take very long to load/execute.
6. For debugging link with -s DEMANGLE_SUPPORT=1 and -s ASSERTIONS=1
7. C++ printf() outputs to the Developer Console: Chrome Settings->More tools->Developer tools
8. If something crashes, try running in Firefox which may explain the error differently.
9. I use Web Server for Chrome for development:

The C FILE I/O functions work, but on a virtual file system:

You can package up individual files from a directory that gets preloaded before your module executes.
To wrap C++ functions, classes, types etc. to expose them to Javascript code, look for "EMSCRIPTEN_BINDINGS". It's quite slick and mostly automatic.
Reading an integer property on a Javascript object from C++:

const emscripten::val& srcBuffer;

unsigned int length = srcBuffer["length"].as();
Copying from a Javascript Uint8Array to a std::vector:
And the reverse: copying from a std::vector to a Javascript Uint8Array (which was sized in Javascript to be >= the size you want to copy):
To JavaScripte/WebAssembly wizards all of this is probably the most basic beginning stuff. However, to native C++ coders not very familiar with these technologies (like me), all of this takes a while to figure out.
I use "emcmake cmake ../" in my build directory, with my CMakeLists.txt file in the parent folder. It sets environment variables that CMake needs to use emcc (the compiler).
All the heavy lifting that I do (data compression, decompression, transcoding)- stuff that doesn't require external API access - is in C/C++. Pretty much everything else, like the UI, WebGL usage, etc. is written in Javascript.
WebAssembly SIMD is the tech you want to use for SIMD in the web world. Personally, I use the intrinsic function wrappers. Functionality wise it seems vaguely somewhere in between SSE v2 and v4.
Multithreading support is still the wild west. I wouldn't depend on it being available yet in all browsers:

There has been speculation that changes to the way the internet is implemented will be rolled out to allow access only to authorized sites.

Some think this is impossible

I'm here to tell you it is not, and very likely.

Allowing access only to white listed IP addresses is easy.

The vast majority access the internet via their Internet Service Provider, and ISP's can easily block client access to any IP address they choose.

China has been doing this for years.

This is how firewalls work, and is much lower level than DNS blocking.

I would imagine this will be rolled out to 'Combat the ever growing threat of Cyber Attacks'.

Most people only use a few thousand services like Twitter, Facebook, Amazon, Google, Microsoft, TikTok, Snapchat, Instagram, Reddit etc, Walmart, Costco, Tesco, Morrisons etc. as it is.

It will be easy over time to require 'legal registration' for any and all other services and sites.

We already took a step toward this years ago anyway, so this is just the logical next step.

As 5G technology is rolled out in your city, more and more control is being introduced at the street level, using what are known as 'Edge Servers'.

While making services faster to access, it also allows an additional layer of security and access control at the local level.

7 Tactics To Increase Engagement on Your Threads

// THREAD //

People are constantly seeing the same stuff over and over again on their timeline.

This is why you need to learn how to stand out.

When they’re scrolling you need to grab their attention and reel them into something they want to read.

If you think about it, your job is just to get them to click your tweet. Once that’s done, they’ll be reading your other ones in no time.

In order to get them to click you need to show one of these 7 things:
> authority
> experience
> value
> lesson
> mystery
> opinion
> numbers

The easiest way to write headlines based off of these things is to write out your audience’s objections.

Then, indirectly counter their objection within your headline (sounds cool right?).

An old copywriting trick 😉

1. Authority

“Why should I read your thread? What have you done that makes me trust you”

Headline:
“$97,840 in Profit This Month Using This 5-Step Plan to Make Landing Pages”

Authority shows people you know what you’re doing by telling them a true stat/claim.

If you're interested in DB internals, stop what you're doing and watch @CMUDB Quarantine Talk from Nico+Cesar about @SQLServer's Cascades query optimizer: https://t.co/FCdsbHHEaD

Many talks this semester were good. This one is the best. My thread provides key takeaways

[6:50] Microsoft hired Goetz Graffe in the 1990s to help them rewrite original Sybase optimizer into Cascades. This framework is now used across all MSFT DB products (@SQLServer, @cosmosdb, @Azure_Synapse).

[14:43] The optimizer checks whether it has stats it will need before cost-based search. If not, it blocks planning until the DBMS generates them. This is different than other approaches we saw this semester where DBMS says "we'll do it live!" with whatever stats are available.

[21:05] Their Cascades' search starts small/simple and then they make decision on the fly whether to expand search based on the expected query runtime and performance benefit from more search.

[26:33] They explicitly have a property for Halloween Problem. Operators specify whether they protect from it and then optimizer ensures property is satisfied. This is mindblowing. I have never thought about using the optimizer for this but it makes sense.

Chess may be a good analogy for explaining the difference between a descriptive model of reality and a generative model of reality.

A descriptive model of chess will describe the rules (i.e. initial setup, allowed moves, points per piece, objectives). This tells you how a chessboard might evolve and also narrows the combinations of realistic chess positions.

In contrast, a generative model involves the actual gameplay between competing players that follow the rules. It generates new styles and patterns. It establishes new strategies and tactics. It generates new openings, middle gameplay, and end game tactics.

A generative model is an evolutionary model that leads to emergent behavior. As a consequence, a master of chess is able to recall the layout of chess positions in a real game in an instant, yet is unable to remember pieces placed in random positions.

That is because causality is present in the movements of pieces in a chessboard. An intuitive system like the human mind is able to capture that causality as a means to understanding and recall.

Permanent suspension of @realDonaldTrump
By Twitter Inc.
Friday, 8 January 2021
After close review of recent Tweets from the @realDonaldTrump account and the context around them — specifically how they are being received and interpreted on and off Twitter —


we have permanently suspended the account due to the risk of further incitement of violence. 

In the context of horrific events this week, we made it clear on Wednesday that additional violations of the Twitter Rules would potentially result in this very course of action.

Our public interest framework exists to enable the public to hear from elected officials and world leaders directly. It is built on a principle that the people have a right to hold power to account in the open. 

However, we made it clear going back years that these accounts are

not above our rules entirely and cannot use Twitter to incite violence, among other things. We will continue to be transparent around our policies and their enforcement. 

The below is a comprehensive analysis of our policy enforcement approach in this case.

Overview

On January 8, 2021, President Donald J. Trump Tweeted:

“The 75,000,000 great American Patriots who voted for me, AMERICA FIRST, and MAKE AMERICA GREAT AGAIN, will have a GIANT VOICE long into the future. They will not be disrespected or treated unfairly in any way, shape or form

I hate when I learn something new (to me) & stunning about the Jeff Epstein network (h/t MoodyKnowsNada.)

Where to begin?

So our new Secretary of State Anthony Blinken's stepfather, Samuel Pisar, was "longtime lawyer and confidant of...Robert Maxwell," Ghislaine Maxwell's Dad.


"Pisar was one of the last people to speak to Maxwell, by phone, probably an hour before the chairman of Mirror Group Newspapers fell off his luxury yacht the Lady Ghislaine on 5 November, 1991." https://t.co/DAEgchNyTP


OK, so that's just a coincidence. Moving on, Anthony Blinken "attended the prestigious Dalton School in New York City"...wait, what? https://t.co/DnE6AvHmJg

I'm not going to even mention that Blinken's stepdad Sam Pisar's name was in Epstein's "black book."

Lots of names in that book. I mean, for example, Cuomo, Trump, Clinton, Prince Andrew, Bill Cosby, Woody Allen - all in that book, and their reputations are spotless.

A thread on how absurd the UK is on transgender issues and how the UK got so transphobic

In 2015 Parliament held an inquiry looking into the state of Transgender equality. Trans people of all stripes outlined many different problems across many, many different areas.

As a result Parliament created a list of recommendations including legal recognition for non binary people, gender recognition act reform, allowing 16 year olds to change their legal gender and reform of NHS gender identity services.

The government under Theresa May ignored everything that was recommended except for Gender recognition act reform. This act came into law in 2003 and gave trans men and women (but not non-binary people) the ability to legally change their gender on their birth certificates.

The process at that time to change your birth certificate under the GRA was to make an application to a panel of cisgender people who would decide if you were sufficiently trans based on your payslips, photo ID and bank statements. You would not get the option to speak to them.

(Also this process cost £140 which is just a tax on being trans)

Shy people are either overthinking or highly observant of the social setting.

And in many cases it can be both.

'So what do I do?'

You learn the 75/25 law.

'What is that?'

The law of charisma...👇

Let's address the over thinkers first.

Do you have any idea why you overthink?

'Yea. Because others are judging how shy I am.'

Incorrect.

Others are thinking about themselves, not you.

But the fact that you think they are thinking about you, you fuck up the interaction.

Now you stay in your head too much & avoid the present moment.

A major no no in the social world.

Your tendency to think that others are judging you for being shy, coincidentally makes you more shy.

And that's when you start giving off a strange vibration to the social setting.

This is when you begin attracting comments like 'why are you so quiet?'

@FionaPearman @ScottMorrisonMP Morrison is our statue of unempathic neoliberalism - erected by evangelical and corporate Australia to celebrate their victory over compassion, equality and secular humanism. 

Hopefully it gets pulled down like the statues of dubious heroes of oppression from an earlier age.


@ScottMorrisonMP The two-party-preferred system in 
Australia politics isn’t working for people, and it sure isn’t working for the planet.

@ScottMorrisonMP My collapse of faith in our democracies isn’t an accident. It’s one of the central victories of the neoliberal project, delivered through two generations of privatisation, outsourcing and deregulation, underfunding of government services (locked in by tax cuts),...

@ScottMorrisonMP restricting freedom of information, targeting whistleblowers and raiding the media who report on them, delegitimising and gagging public interest advocacy, and criminalising protest.

@ScottMorrisonMP Politics in Australia today relies hugely on the fact that most people don’t know most of what’s going on so as to get away with stuff that couldn’t be done under real scrutiny we have seen a clear example of this with the National Coronvirus Cabinet.
