At the start of my career in IT, #mainframes were the spearhead of computing, especially in high-throughput business applications. Soon, distributed computing overtook centralised mainframes, fuelled by cheap, powerful RISC servers and workstations.
Today, the bulk of the computing workload is handled by the cloud computer. And a large portion of that computing workload is batch-training AI models. In forty years, we have circled back to full-blown "centralised, batch computing" model.
Yet, we are running UNIX-derived timesharing OSs (BSD, Linux, etc.) on those cloud-borne compute nodes, configured in the distributed computing fashion.
For a private compute #cloud (one that is used exclusively by one business entity or one scientific research group), a stripped-down, batch-processing OS would be a more sensible choice:
• For transaction-processing workloads, this batch OS could be running in parallel I/O mode.
• For data-crunching workloads, this batch OS could be running in a parallel distributed compute mode.Moreover, security and other power-sapping facilities unrelated to the compute workloads should be excised out of the kernel, since the whole lot is privately owned and operated by one trusted entity, and is externally guarded by network security mechanisms, like firewalls, trip sensors, etc.
In other words, each compute workload makes a direct, unhindered use of the entire compute cluster, much like a single game uses the GPU on a gaming PC.
The cluster can also be shared by multiple groups within the organisation. Each group will be allotted a portion of the cluster, completely isolated from the rest of the cluster.

IBM's ancient #training #film resurfaces like a relic from the digital Stone Age, desperately trying to keep its secrets away from the prying eyes of the 21st century 😂🔒. An archaeological masterpiece for those nostalgic about punch cards and #mainframes 📼💾.

Somewhere, right now, a developer is sorting 400 COBOL cards off a computer room floor after a late night of keying. Nobody wants to look at it. Nobody cares.
But we do.
Announcing code review for Punch Cards, powered by Review Board.

Hilarious sentence from Josh Tyrangiel in an essay for the March Atlantic:
“Mainframes are like Christopher Walken: They’ve been going nonstop since the 1960s, they’re fantastic at performing peculiar roles (processing payment payments, safeguarding data), and nobody alive really understands how they work.”

@don_atoms And, in our opinion, the most important radical act of our era is giving a top-tiier Open Source #COBOL compiler (#GCC COBOL) to those who need help with the hundreds of billions of lines of COBOL source trapped on #mainframes. Giving control of the tool to those who need it. #cobolworx

Образцовый джун
Показываю на конкретном примере как выглядит идеальный «вкат в ИТ» — с почетом и уважением от старших коллег и карьерой, сразу же улетающей ракетой в космос.
