GitHub puts prebuilt Codespaces into public beta

Say goodbye to your coffee break


Microsoft's GitHub on Wednesday said customers using its Codespaces hosted development environments can now try out prebuilt systems in a public beta test.

A prebuilt Codespace is basically a template consisting of source code, code editor extensions, project dependencies, commands, and settings that have been downloaded already.

The reason one might prefer a prepackaged Codespace is that building one from scratch can take time. When The Register tried doing so in December, 2020, several months after the service first was announced, it took several minutes to create and configure the virtual environment. That's not as tedious as compiling a browser from source code or waiting hours for an AI model to be trained. But it's still time that could be better spent.

"Our primary goal with Codespaces is to provide a one-click onboarding solution that enables developers to get started on a project quickly without performing any manual setup," said Tanmayee Kamath, senior product manager at GitHub, in a blog post.

"However, because a Codespace needs to clone your repository and (optionally) build a custom Dockerfile, install project dependencies and editor extensions, initialize scripts, and so on in order to bootstrap the development environment, there can be significant variability in the startup times that developers actually experience."

When GitHub began using Codespaces internally, the virtual environments would take 45 minutes to activate in some cases. Software engineering work drove startup times down to five minutes and using prebuilds dropped that to about 10 seconds.

Having completed a private preview for prebuilds with roughly 50 organizations, GitHub has incorporated feedback and is now making its virtual coding environment quickstart available as a public beta.

Public beta users can now choose faster startup times by picking a machine type with a "prebuild ready" tag.

Action time

These Codespaces can be set by repository admins to use specified prebuild configurations for different repo branches and regions. And GitHub has woven in support for GitHub Actions, to automate managing various workflow scripts for different branches.

"Prebuild configurations are now built on GitHub Actions virtual machines," said Kamath. "This enables faster prebuild template creations for each push made to your repository, and also provides repository admins with access to a rich set of logs to help with efficient debugging in case failures occur."

Now that rough spots like secrets management appear to have been ironed out and wait times have been tamed, it may be worth another look at cloud coding environments, if you're not fundamentally opposed to the idea.

Codespaces is currently available to GitHub Teams and GitHub Enterprise customers because cloud VMs cost money to run. Those looking for a free tier offering may wish to consider GitPod, which offers a similar service and has been around longer. ®

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register. "We need to put our assets in place off our planet, where we can keep it safe."

    Also, Chinese IT admin jailed for deleting database, and the NSA promises no more backdoors

    In brief The notorious Russian-aligned Conti ransomware gang has upped the ante in its attack against Costa Rica, threatening to overthrow the government if it doesn't pay a $20 million ransom. 

    Costa Rican president Rodrigo Chaves said that the country is effectively at war with the gang, who in April infiltrated the government's computer systems, gaining a foothold in 27 agencies at various government levels. The US State Department has offered a $15 million reward leading to the capture of Conti's leaders, who it said have made more than $150 million from 1,000+ victims.

    Conti claimed this week that it has insiders in the Costa Rican government, the AP reported, warning that "We are determined to overthrow the government by means of a cyber attack, we have already shown you all the strength and power, you have introduced an emergency."

    The new campaign, dubbed Twisted Panda, is part of a larger, state-sponsored espionage operation that has been ongoing for several months, if not nearly a year, according to the security shop.

    In a technical analysis, the researchers detail the various malicious stages and payloads of the campaign that used sanctions-related phishing emails to attack Russian entities, which are part of the state-owned defense conglomerate Rostec Corporation.

    The US Federal Trade Commission on Thursday said it intends to take action against educational technology companies that unlawfully collect data from children using online educational services.

    In a policy statement, the agency said, "Children should not have to needlessly hand over their data and forfeit their privacy in order to do their schoolwork or participate in remote learning, especially given the wide and increasing adoption of ed tech tools."

    The agency says it will scrutinize educational service providers to ensure that they are meeting their legal obligations under COPPA, the Children's Online Privacy Protection Act.

  • Mysterious firm seeks to buy majority stake in Arm China
    Chinese joint venture's ousted CEO tries to hang on - who will get control?

    The saga surrounding Arm's joint venture in China just took another intriguing turn: a mysterious firm named Lotcap Group claims it has signed a letter of intent to buy a 51 percent stake in Arm China from existing investors in the country.

    In a Chinese-language press release posted Wednesday, Lotcap said it has formed a subsidiary, Lotcap Fund, to buy a majority stake in the joint venture. However, reporting by one newspaper suggested that the investment firm still needs the approval of one significant investor to gain 51 percent control of Arm China.

    The development comes a couple of weeks after Arm China said that its former CEO, Allen Wu, was refusing once again to step down from his position, despite the company's board voting in late April to replace Wu with two co-chief executives. SoftBank Group, which owns 49 percent of the Chinese venture, has been trying to unentangle Arm China from Wu as the Japanese tech investment giant plans for an initial public offering of the British parent company.

  • SmartNICs power the cloud, are enterprise datacenters next?
    High pricing, lack of software make smartNICs a tough sell, despite offload potential

    SmartNICs have the potential to accelerate enterprise workloads, but don't expect to see them bring hyperscale-class efficiency to most datacenters anytime soon, ZK Research's Zeus Kerravala told The Register.

    SmartNICs are widely deployed in cloud and hyperscale datacenters as a means to offload input/output (I/O) intensive network, security, and storage operations from the CPU, freeing it up to run revenue generating tenant workloads. Some more advanced chips even offload the hypervisor to further separate the infrastructure management layer from the rest of the server.

    Despite relative success in the cloud and a flurry of innovation from the still-limited vendor SmartNIC ecosystem, including Mellanox (Nvidia), Intel, Marvell, and Xilinx (AMD), Kerravala argues that the use cases for enterprise datacenters are unlikely to resemble those of the major hyperscalers, at least in the near term.
