Rust Compiler Performance Triage

This week the good outweighed the bad. In particular, we had three different PRs that made improvements to a wide range of benchmarks. Special call out to PR #111026, which yielded 3% to 8% improvement for incremental compile times on a large set of benchmarks, by avoiding unnecessary caching in the type checker.

Triage done by @pnkfelix. Revision range: fdeef3ed..a368898d

Quote of the Week

Since it hasn't been said before, there is an important distinction that needs to be addressed. For anyone who has been doing embedded work for any length of time and hasn't yet been exposed to Rust, the only thing that can really be said is that the language is entirely unlike everything you've experienced before. There is just nothing comparable, and the only way to rationalize questions like why use Rust at all is to put some honest effort into learning and using it.

Hearing things like "it's a bit like C++ except it's memory safe and thread safe, and it's actually practical to build kernels with it" will not sound convincing. You have to see it to believe it.

It's as if you've spent an entire career writing assembly, and one day you hear something or other about a brand-new programming language claiming to be a "portable assembler" called C. It sounds too good to be true. And then the years pass, and all of the mystery and disbelief gives way to obviousness and precision engineering. That's sort of how it is when going from C to Rust.

– Jay Oster

Thanks to Michael Bryan for the suggestion!

ⅺ , @wasme ( . . . ) eleven ? ➥ starter call.

when the walls had trembled, a familiar dread rolled against her chest. hand balled into fist as the lights flicker -- her brown eyes tore wide open, looking for a CRACK, for the crumble. but it had settled too easily, too quietly. she wants to go to the radio, call hopper and let him know SOMETHING was here. but at once, she wasn’t afraid, no. she could protect herself, even if he thought she needed help. she peaks out from the windows. rule one : keep the blinds closed. she sees something BLUE -- BIG in the distance, like a long square. a door opens, and a man gets out. in fright, she lets the blinds fall loudly against the window’s glass. not stupid. but she almost wants to prove to herself that this wasn’t a THING. hand hovers before the door knob, she flies the locks off the door with her eyes.

she watches the MAN travel closer . . . maybe he needed help, even if he looked okay. but eleven notices he’s traversing very closely to the tripwire. something in her says he might just be lost, and she knows how that feels. she doesn’t want him to get hurt. swinging open the door, she makes a snap decision, “ wait ! there’s the tri- trippy wire ! ”

Unicork, a unicorn cockscrew

The Unicork [Amazon] is a corkscrew in the shape of a unicorn, its body the handle and its horn the screw. Customer reviews are superlative.

"I was impressed by the general heft of the unicorn, and it pulled my cork as I might expect," writes Max Kucinich. "I especially appreciated the prancing posture of the animal, as it allowed me to take a strong grip when pulling."

"I was shocked at how heavy it wasm" writes Michael. "...It also works well on beer bottles"

"The iPhone of bottle openers," adds Sam.

Mercari x Merpay Frontend Tech Talk vol.4 を開催しました

from https://tech.mercari.com/entry/2020/01/24/100000

Merpay でフロントエンドエンジニアをしている @_sskyu です。1月15日に Mercari x Merpay Frontend Tech Talk vol.4 が開催されました。私も登壇者として参加したので、当日の発表の様子を紹介します。

Pros and Cons of SSR and JAMstack

最初に私が「Pros and Cons of SSR and JAMstack」という発表をしました。昨年の8月から取り組んでいたもので、キャンペーン用のマイクロサービスのパフォーマンスが出ない問題を調査して、JAMstack 構成の環境に移行したという内容で発表しました。

speakerdeck.com

※JAMstack: JavaScript + API + Markup を使った Web アプリケーションアーキテクチャ。

NoCode で CMS と連携するデザインツールを作っている話

2つ目の発表は STUDIO の @miyaoka さんで、「NoCode で CMS と連携するデザインツールを作っている話」です。STUDIO では静的なLPなどはすでにNoCodeで作れる状態にあるそうですが、今は動的なサイトを作れるように開発をしているという内容でした。

slides.com

TypeScript で型安全に入門したい

3つ目の発表はフリーランスの @atsuco_02 さんで「TypeScript で型安全に入門したい」です。未経験者が TypeScript に入門するときのハードルを下げてくれるような内容で、わかるわかると思いながら聞いていました。CodeSandbox を利用すると面倒な開発環境の構築をスキップできるので良いですよね。

speakerdeck.com

Web Assembly と画像・動画

最後の発表は LINE の @Leonardo_engr さんで「Web Assembly と画像・動画」です。急遽代打で登壇されたということでしたが、WASM を使って ImageMagick をブラウザで動かすという素晴らしいデモを披露してくれました。

speakerdeck.com

おわりに

今回の Tech Talk は 4 名それぞれが異なる領域の話だったので、普段の業務で触れない技術やナレッジを知れて刺激になりました。次回は3月に開催を予定しているので、今回参加できなかった人や興味が湧いた人は是非ご参加ください！

The future of audiovisual touch panel designs will be objects (buttons, levels, images, pages) that can adapt to changes in code — such as WebAssembly, #Crestron CH5 & #AMX JSON/ JavaScript. WebAssembly (wasm) is an important new browser capability…https://t.co/iCVwRxCOLW

Es terrible no poder dormir, ¿verdad? Las consecuencias de no dormir o de dormir poco se reflejan inmediatamente al día siguiente: cansancio, ojeras, malestar general y sentimos una especie de agotamiento en nuestro cerebro. Dormir las ocho horas diarias de forma placentera es el reflejo de una buena salud física y mental. Pero hay algo preocupante y es que según los expertos cada vez dormimos menos. Lo dice la WASM (Asociación Mundial de Medicina del Sueño). En reiteradas oportunidades hemos leído sobre los buenos hábitos alimenticios, y la importancia de la actividad física, pero poco se habla de la importancia de dormir bien

La entrada Consecuencias de No dormir o Dormir Poco se publicó primero en Consejos de Vida Saludables.

GoChain blockchain available on Azure

The team at GoChain is bringing their private, scalable blockchain offering to Microsoft Azure. GoChain is a smart contract blockchain based on a go-ethereum code fork, with changes to protocol and consensus model primarily to increase the transaction speed of the network. This is acheived through core protocol changes as well as the introduction of Proof of Reputation consensus mechanism. This function similar to the current Proof of Authority based models in that verification of blocks are controlled by validation nodes agreed upon by the consoritium.

GoChain is an Ethereum compatible blockchain which enables enterprise customers and developers the ability to build and deploy decentralized applications and smart contracts. With this compatibility, existing Ethereum assets can be reused with little changes require, such as solidity based smart contracts.

Enterprises are looking for blockchain solutions that allow them to take advantage of core blockchain attributes such as immutability, strong digital signatures, and distributed architecture. However, they have needs that differ from public based chains in that they have controlled participants on the network. Solutions such as GoChain allow this type of deployment.

Upgradeable Smart Contracts

An area that the team at GoChain has been focused on is enabling a more friendly option to upgrade existing smart contracts. Smart Contracts are immutable by the very nature of protocol. While this leads to a strong assurance and trust model, enterprises are asking for patterns to upgrade existing deployed contracts. A few options have emerged, however GoChain is working on a model that moves functionality such as the ability to pause a smart contract from an inherited library or contract to the protocol level. Additionally, enabling a better governance model around upgradability rules via a voting mechanism is another enhancement the team is enabling. GoChain is targeting January 2019 for this update.

Other roadmap items

In addition to the core protocol and upgradable smart contracts, GoChain is also working on the following areas for near term releases:

Multi-Node deployment template.

Prioritized peer broadcasting to authorized signers.

Archive/backup of chain data off-node to cloud storage.

WASM contract support.

How can I get started?

Check out the free offering in the Azure Marketplace.
