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:

Let's be clear about what @Google, @Apple & @amazon instantly destroying #Parler's ability to be the free-speech version of Twitter is. At its core, this is about the ability to freely communicate one’s thoughts to others — once considered a hallmark of "The American Way." 1/13

What Big Tech is doing is as if Ma Bell in 1973 (ask grandpa) decided what you're saying to a friend on a landline phone was “dangerous." So they cut off the line in the middle of the talk and then sent someone over to physically cut your phone line. That's Stasi shit. 2/13

I realize that a personal conversation is not the same as a public tweet, but the principle is the same. The company that "owns the wires" for your speec — and has special govt rules protecting them due to their position — cuts off your call due to what you are saying. 3/13

If this analogy doesn't work for you, imagine someone tackling and punching you for speaking on a soap box in a public park and then setting your soap box on fire. And the govt being OK with that in a country that has a First Amendment. Moving on ... 4/13

Big Tech shadow banned people for years to just do it "halfway." That way, they could continue to paint an increasingly thin patina on their original govt-protected pledge to promote the free exchange of thought. #freespeech 5/13

Here's an overview of key adoption metrics for deep learning frameworks over 2020: downloads, developer surveys, job posts, scientific publications, Colab usage, Kaggle notebooks usage, GitHub data.

TensorFlow/Keras = #1 deep learning solution.


Note that we benchmark adoption vs Facebook's PyTorch because it is the only TF alternative that registers on the scale. Another option would have been sklearn, which has massive adoption, but it isn't really a TF alternative. In the future, I hope we can add JAX.

TensorFlow has seen 115M downloads in 2020, which nearly doubles its lifetime downloads. Note that this does *not* include downloads for all TF-adjacent packages, like tf-nightly, the old tensorflow-gpu, etc.


Also note that most of these downloads aren't from humans, but are automated downloads from CI systems (but none are from Google's systems, as Google doesn't use PyPI).

In a way, this metric reflects usage in production.

There were two worldwide developer surveys in 2020 that measured adoption of various frameworks: the one from StackOverflow, targeting all developers, and the one from Kaggle.

I was hacking a game and accidentally invented a word for when you think someone is trans and you're proud of them for coming out but then you find out they aren't


someone is excited to watch bill nye in science class


This happens because one of the ways I figure out which memory location needs to be modified is by memory-searching for all occurrences and changing the first letter of them

so like if I know the next line of dialog is "Die"
I change it to "Aie" "Bie" "Cie" "Eie" "Fie"

then I see which one shows up in the game

THREAD: Now that @Amazon @awscloud has announced they will no longer host @parler_app, many have speculated that they will just “find another host.”

Here is why that’s not so simple and what it will likely mean for the app’s future. First, let’s look at where things are...

2/ Google and Apple have removed the app from their app stores, effectively terminating growth on mobile devices. People can still access the (not good) web UI until Amazon terminates them today. CEO Matze has said they may be down “up to a week” while they find new hosting.

3/ Translated to English, that’s code for “we have no idea what’s going to happen next.” No US cloud provider (Microsoft, Google, IBM, Digital Ocean) is likely to touch this, as it could be seen as providing material support for sedition. No CEO or counsel wants to get near this.

4/ They could potentially “roll their own” data center by buying servers and putting them in a co-location facility. But that’s a single point of failure, and many colo providers would be just as likely to decline their business. It would be hard and risky to pursue this.

5/ Imagine, after they sweated like pigs to get this hardware all setup, if they get told their colo provider is booting them. That’s a lot of metal to then move somewhere else. Meanwhile, the user base is deteriorating because chaos and dying apps. They will go to other venues.

A thread on teaching live lessons using @MicrosoftTeams Meet Now function where students follow their normal timetable except online - will go into more detail on every point in a blog post later. Have used Teams for live teaching have supported over 100 live lessons since March

1. If you are using the desktop app, check you have the latest version of Teams so that you should have Breakout rooms enabled. Check by clicking your profile picture, then About - I have version 1.3.00.28779. If you have 1.2..., click on check for updates to get the latest


2. Set your entry routine. I get my students to enter with their microphone muted - you can also not allow attendees to unmute by opening the participants list, clicking the ellipsis and selecting that option.


3. Make sure students arrive as attendees - some organisations have this set up to automatically happen that only meeting organizer is the presenter and others are attendees. Can change this in the manage permissions menu to only me if not already set (opens in a web browser).


4. Classroom routine and expectations - first lesson I share my screen and show the students the raise hand function for when they want to ask questions, how to access the chat function and how to react to questions as opposed to typing answers

1. “Who Are Ireland’s Members Of The World Economic Forum Implementing The Great Reset In 2021 ? 🧵1/28

🕵️🔎 Politicians, Musicians, Clergy, Bankers, Journalists, Human Rights, Artificial Intelligence, Sustainability, Corporations & Agriculture


2. In previous threads I have looked at 🇮🇪 key players in the Trilateral Commission as well as 🇮🇪 people who have attended the Bilderberger meetings. I also looked at the 🇮🇪 in the Young Global Leaders which is a site run by the WEF. You will see a lot of crossover between them.

3. The purpose of this thread is to compile all the Irish members into one thread for ease of access and reading rather than having to dive through the WEF site. This is by no means definitive and I will be adding more over time when they pop out of the woodwork.

4. Ireland’s WEF members are drawn from all walks of life but can be split into 2 separate areas. The WEF calls the first category “people” and the 2nd one “agenda contributors”. In total Ireland has a minimum of 61 members. Some of the names will be familiar and others will not

5. In this thread I’m just going to concentrate on the 21 people (there are probably a lot more). There are also 40 “agenda contributors” which I will cover in a separate thread. The agenda contributors are those who write articles or do research for the WEF site.

कुंडली में 12 भाव होते हैं। कैसे ज्योतिष द्वारा रोग के आंकलन करते समय कुंडली के विभिन्न भावों से गणना करते हैं आज इस पर चर्चा करेंगे।
कुण्डली को कालपुरुष की संज्ञा देकर इसमें शरीर के अंगों को स्थापित कर उनसे रोग, रोगेश, रोग को बढ़ाने घटाने वाले ग्रह


रोग की स्थिति में उत्प्रेरक का कार्य करने वाले ग्रह, आयुर्वेदिक/ऐलोपैथी/होमियोपैथी में से कौन कारगर होगा इसका आँकलन, रक्त विकार, रक्त और आपरेशन की स्थिति, कौन सा आंतरिक या बाहरी अंग प्रभावित होगा इत्यादि गणना करने में कुंडली का प्रयोग किया जाता है।


मेडिकल ज्योतिष में आज के समय में Dr. K. S. Charak का नाम निर्विवाद रूप से प्रथम स्थान रखता है। उनकी लिखी कई पुस्तकें आज इस क्षेत्र में नए ज्योतिषों का मार्गदर्शन कर रही हैं।
प्रथम भाव -
इस भाव से हम व्यक्ति की रोगप्रतिरोधक क्षमता, सिर, मष्तिस्क का विचार करते हैं।


द्वितीय भाव-
दाहिना नेत्र, मुख, वाणी, नाक, गर्दन व गले के ऊपरी भाग का विचार होता है।
तृतीय भाव-
अस्थि, गला,कान, हाथ, कंधे व छाती के आंतरिक अंगों का शुरुआती भाग इत्यादि।

चतुर्थ भाव- छाती व इसके आंतरिक अंग, जातक की मानसिक स्थिति/प्रकृति, स्तन आदि की गणना की जाती है


पंचम भाव-
जातक की बुद्धि व उसकी तीव्रता,पीठ, पसलियां,पेट, हृदय की स्थिति आंकलन में प्रयोग होता है।

षष्ठ भाव-
रोग भाव कहा जाता है। कुंडली मे इसके तत्कालिक भाव स्वामी, कालपुरुष कुंडली के स्वामी, दृष्टि संबंध, रोगेश की स्थिति, रोगेश के नक्षत्र औऱ रोगेश व भाव की डिग्री इत्यादि।

Ancient Egypt was the most advanced civilization in the ancient world. Why was Egypt so special?

There are so many firsts in Egypt that we all know about, and that makes Egypt unique. For example, the Sumerians did not build the pyramids of Egypt.
