Will Hare replace C? Or Rust? Or Zig? Or anything else? May 2, 2022 by Drew DeVault Nope. If the short answer leaves you wanting, keep reading. I must admit that this sentence from the Hare announcement may have caused some confusion: Hare is most similar to C, and almost all programs written in C can also be written in Hare. This is especially true in the context of the rising and competing compl
The best online collaboration tools Teams need tools to help them collaborate and stay productive while remotely working. Here's our top picks. Read now By default, GitHub uses the term "master" for the primary version of a source code repository. Developers make copies of the "master" on their computers into which they add their own code, and then merge the changes back into the "master" repo. "O

Let's look at how long Macs last, then discuss some of the major signs that your Mac is out of date. We'll show ways you can work around th
Home Definitive answers and clarification on the purpose and use cases for Context and Redux Introduction 🔗︎ "Context vs Redux" has been one of the most widely debated topics within the React community ever since the current React Context API was released. Sadly, most of this "debate" stems from confusion over the purpose and use cases for these two tools. I've answered various questions about Co

Imagic offers text-conditioned, fine-grained editing of objects via the fine-tuning of diffusion m
Description: master/slave terminology is offensive and should be replaced with something more appropriate, such as primary/replica. Some technology vendors have already done so. See wikipedia page here: https://en.wikipedia.org/wiki/Master/slave_(technology) How to repeat: View any documentation page about replication in general, for example: https://dev.mysql.com/doc/refman/8.0/en/replication-opt
Unicodeの絵文字の文字列操作は興味深い。 前提知識 「👨👩👧👦」という絵文字は、そういう1文字(コードポイント)が存在するわけではない。 「👨👩👧👦」は「👨」「👩」「👧」「👦」という4つの絵文字とZero Width Joiner(U+200D)という文字の組み合わせのデータで表現される: console.log( '👨' + '\u{200D}' + '👩' + '\u{200D}' + '👧' + '\u{200D}' + '👦' ) //=> 👨👩👧👦 上記のとおり、「👨👩👧👦」はデータとしては7文字なのだが、表示上1文字分の幅になっているだけなのである。 ちなみにJavaScriptのfor ... ofは文字列をコードポイントごとにループできるので、「👨👩👧👦」をforで回すと構成文字に分
I can be quite passionate about image codecs. A “codec battle” is brewing, and I’m not the only one to have opinions about that. Obviously, as the chair of the JPEG XL ad hoc group in the JPEG Committee, I’m firmly in the camp of the codec I’ve been working on for years. Here in this post, however, I’ll strive to be fair and neutral. The objective is clear: dethroning JPEG, the wise old Grandmaste
Since Apple’s introduction of M1 chip in 2020 I was primarily interested in its usage for ML training. Though, then it was only about inference with Neural Engine. However, after the announcement of the new M1 Pro/Max sillicons and the release of PluggableDevice for Tensorflow, it became possible to train models using the GPU. Comparisons of the maxed-out M1 Max with top-end GPU models are already
Starting today, Amazon EC2 supports the replacement of instance root volume using an updated AMI without requiring customers to stop their instance. This allows customers to easily update their applications and guest operating system, while retaining the instance store data, networking and IAM configuration. Customers can use the feature to patch their software quickly without having to incur the
goで複数のモジュールを組み合わせて機能を実装する場合にgo.modでモジュールをimportして使うのですが、importしたモジュール側に実際にどんな値が渡されてきているのかを調べたい場合にモジュールにデバッグコードを追加してpushし、利用側で変更したモジュールを更新する必要があります。 1回で済めばいいのですがそういうわけにもいかずかなり手間がかかってしまいます。 また、自分で作ったモジュールであればpush可能ですが、そうでない場合も多いかと思います。 そこでgo.modのreplaceを使ってgithubからimportするのではなくローカルのモジュールをimportする方法をご紹介します。
The code-hosting portal is just the latest in a long line of tech companies and open source projects that have expressed support for removing terms that may be offensive to developers in the black community. This includes dropping terms like "master" and "slave" for alternatives like "main/default/primary" and "secondary;" but also terms like "blacklist" and "whitelist" for "allow list" and "deny/

JavaScriptのreplace()で複数の文字または文字列を全て一括で置き換える方法の紹介です。 指定の文字列をひとつ置き換える最初に見つかった指定文字列または文字をひとつだけ置き換える場合は正規表現を使わずに実装可能です。 サンプルでは最初に見つかった「aaa」だけが「ccc」に置き換えられていることが確認できます。 let text = `aaa aaa aaa`; text = text.replace('aaa', 'ccc'); //ccc aaa aaa指定の文字列を全て置き換える特定の文字列または文字を全て置き換えるには正規表現と正規表現の「gオプション」を使った実装方法が簡単です。 正規表現では「gオプション」を指定することで対象の文字が複数回含まれている場合、その全てを置き換える事が可能です。 let text = `aaa aaa aaa`; text = tex

Turn your phone into a productivity powerhouse with these accessories, apps, and services. As mobile technology evolves every year, our smartphones' computing power is exponentially growing. The most powerful Snapdragon chipsets have comparable processing power versus Intel's i5 chips. As such, it's not a far-fetched idea to use our Android phones like portable computers. In fact, Samsung has laun
ChatGPT. A sequence of letters that didn’t mean much to people a few months ago is now ubiquitous. It seems like every social media post mentions ChatGPT (especially the latest version, 4) and hypes it as a game changer. It’s been used to quickly summarize text, do homework, pass the bar exam, and code the game Duck Hunt from scratch. It’s been included as a feature in some UX software, and some h
Net Zero Bombshell: The World Does Not Have Enough Lithium and Cobalt to Replace All Batteries Every 10 Years – Finnish Government Report Influential elites are either in denial about the horrifying costs and consequences of Net Zero – witness last Wednesday’s substantial vote against fracking British gas in the House of Commons – or busy scooping up the almost unlimited amounts of money currently
Microsoft is laying off dozens of journalists and editorial workers at its Microsoft News and MSN organizations. The layoffs are part of a bigger push by Microsoft to rely on artificial intelligence to pick news and content that’s presented on MSN.com, inside Microsoft’s Edge browser, and in the company’s various Microsoft News apps. Many of the affected workers are part of Microsoft’s SANE (searc

You know how there are JavaScript dialogs for alerting, confirming, and prompting user actions? Say you want to replace JavaScript dialogs with the new HTML dialog element. Let me explain. I recently worked on a project with a lot of API calls and user feedback gathered with JavaScript dialogs. While I was waiting for another developer to code the <Modal /> component, I used alert(), confirm() and
China’s “New IP” proposal to replace TCP/IP has a built in “shut up command” for censorship The Chinese government and the Chinese telecommunications companies such as Huawei under its control are proposing a “New IP” addressing system for the internet to replace TCP/IP. The New IP system includes top-down checks and balances and such features as a “shut up command” that would allow a central cont
With major aspects of our lives transitioning into a virtual world, it's not surprising that our wallets can potentially be replaced by our smartphones, too. Apple announced some new significant features at WWDC21 for it's digital wallet, Apple Wallet.

JSer.info #556 - Electron 14.0.0がリリースされました。 Electron 14.0.0 | Electron Blog 依存がそれぞれChromium 93、Node.js 14.17.0、V8 9.3へとアップデートされています。 破壊的な変更としてapp.allowRendererProcessReuseオプションの削除、worldSafeExecuteJavaScriptオプションを削除(trueがデフォルト)されています。 また、Electron 12でDeprecatedとなっていたremoteモジュールを削除し、@electron/remoteという外部モジュールへと変更されています。 RendererとMain(Node.js)のやり取りには、基本的にはcontextBridgeを使っていく方向になっています。 Electron(v.14.0.
はじめに タイトルのとおりですがシェルスクリプトで文字列を置換する replace_all 関数を作りました。一応テストはしているのですがまだ実戦投入はしていません。もしかしたら仕様変更するかもしれないしバグもあるかもしれませんありました、後日修正しますが、関数だけでも十分利用価値がある(例えば HTML エスケープなどもこの関数を使えばシェル依存することなく簡単に実装することができるはずです。)のと、これを題材に私のコーディングスタイルの解説をするのにちょうど良さそうだと思ったので記事として公開します。 ちなみに実は同等の関数は以前に作成しているのですが、今とコーディングスタイルが異なってるのと当時はいきあたりばったりで実装していたので再実装しています。近いうちに今使っている実装と置き換える予定ですがまだ十分テストが出来ていません。(Linux以外のOSでクリティカルな問題が発生しないこ
