That time a techie accidentally improved an airline's productivity

yoganmahew

Even in the 1980s, a TPF system (2.4 or 3.1, most likely 2.4) had at most 32 mb and on that supported thousands of terminals round the world. a 2.4 system was 31 bit, but only used 24 of them, meaning there was a byte available in every word that stored a core address that could be misused... the conversion from 24 bit to 31 bit was excruciatingly boring (check every core address use).

In addition transmission costs were hideous and you got very few bods. I remember a user coming to me, then a very junior programmer, wondering who UNA PROC was, or UNABLE TO PROCESS.

The glory days of every airline having their own TPF (or ALCS) system are pretty much gone, but I still make a living wrangling Teletype... the past is still the present. What's interesting with K8S is that it exhibits many of the characteristics of a mainframe cluster...

The application layer is still tty format, as you say, some of which dates from the fifties... (pre-automation). That it has survived this long tells you a lot about its reliability, flexibility, and fault tolerance as a standard.

Tape is quick if it is distinct. Like other commentators, I suspect they had a backup of everything written horizontally (maybe even at disk level?) that they're now trying to extract little vertical slices from. If you backed up everything in a customer instance logically to tape, it would be trivial to restore.

The Souls noob's guide to Elden Ring

Re: Nearly bought the game

I'm in my 50s and similarly arthritic. I'm on PS5 - I think the controller is easier to use. Anyway, I bought the game a couple of weeks ago, escaping from the incessant PvP drive that suits younger gamers, but not us fumblers. Like Gene Cash, I use gaming to get away! I admit I'm completely lost, and death becomes me, but I'm gradually discovering who I can beat. I haven;t taken on any serious bosses yet, but so far, timing is more important than speed, and timing is about finger memory, so hopefully my fingers will stop playing Elder Scrolls!

Anyway, thank you Richard for the tips, and I may well watch my first Twitch streams!

Typing is a mistake. You should always be suspicious of external data. Mostly you should be suspicious of internal data too. If you don't understand the variable on the previous line of code, you should be suspicious of that too.

IBM confirms new mainframe to arrive 'late in first half of 2022'

yoganmahew

Re: odd wording

Each new generation is a step up from the previous one. So you get to run more workload per unit cost of infrastructure, lowering your cost per transaction. It's a marketing piece to existing customers used to thinking in MIPS and in large percentage improvements. I don't have any exact numbers, but gut memory is that Z series was 40% faster than previous generation. The promise in droid-speak is that the new series will be similarly better.

I don't think there's a similar comparison to other hardware types. The workloads tend to be many small transactions of limited parallelism that require ordered processing and persistence, at least that's my narrow experience! :).

APNIC: Big Tech's use of carrier-grade NAT is holding back internet innovation

yoganmahew

Re: I've said it before and I'll say it again

Absolutely and until technical simpletons like me can look at a nextgen IP address and understand it, nextgen is doomed. Why? Because most of what is done is done by simpletons. IPv6 looks too complicated (it doesn't matter if it is, it looks is).

One solution we folk in the mainframe world hit on often is to make the leading value 'different' so starting at 256.0.0.0. It's convention that says all parts of the address should be the same value. That would let intercarrier communications use an expanded range while leaving the NAT'd addresses within networks still unchanged.

Or is that too simplistic?

Timekeeping biz Kronos hit by ransomware and warns customers to engage biz continuity plans

yoganmahew

Re: It's not getting tagged with ransomeware thats the faceplant.

Absolutely, this "activate you business continuity plan" from a cloud vendor is some high-grade BS. Kronos Cloud is supposed to be a business continuity plan. If you have to manage your own data yourself, back it up, have hardware on standby to run the workloads in-house, have an alternate system, what's the point in outsourcing?

Oh and Kronos time management sucks the big wind... truly awful.

Is it free? Is it cheap? Can you get contractors to do it?

Then it can replace what we have already.

TBH, new process systems are more damaging these days. Everyone does them except poor IT who has to live with the sales system for new prospects, the marketing system for unifying wildly disparate products, the product owner system (so no matter how ludicrously technical your system, some bloke in a suit has to own and direct it), the gazillion forms on SNOW :(

Re: Ermm...

Yeah, and if you're in GCP, Spanner or Firestore as your persistence layer exist whether you care about them or not - they are accessible from your cluster, but outside it.

If what he's further saying is you don't understand what Spanner and Firestore are doing, well, when your last mainframers retire, you won't understand your data centre either.

It's completely unsupportable. Yes, we mean your brand new system

And then you have the "what is core? Baby don't code it" crowd. Those accountants and program managers that effectively run a large organisation. To them, they are core, everything else can be outsourced. So soon your core product is being built by outsourced teams. You will never know what it does or how it does it or how to fix it. It will always be broken in one way or another. Every fix will require a refactoring, change control, and a large project team.

I'm close enough to the end of my career that it's sad, but I no longer care. The battle's lost and the game is too.

Re: There must be a better way to build these systems

Even 30 years ago a mainframe would handle multiple parallel users with no loss of performance, I worked on a system that in 1991 had 20,000 simultaneous connections processing workloads. Every year they get faster and better where now the mainframe I work on supports millions of simultaneous connections.

You can read up on some of the characteristics of what people mean by 'mainframe' here - https://www.suse.com/c/mainframe-versus-server-farm-comparison/

Offloading tightly coupled applications that six people in the company understand well enough to describe the business flows is nightmarish. The lack of people with skills is the reason that mainframe needs to be offloaded, but the same lack of people is what makes it ludicrously hard.

Re: Can you imagine...

Akchley, yes, one important lesson was learned. The middle manager of doom is stupid precisely because they believe that their tinkering is valuable instead of costly.. The cloud is running other people's workloads at profit. If the other people are stupidly inefficient, so much the better. You can kid them that the volume discounts they get for their inefficiency will save them.

Now the middle manager of stupid will run his spreadsheet queries on an unlimited serverless cloud, paying per instruction instead of his hardware limited over-specc'd laptop...
