(disclaimer: I work at Volkswagen) Volkswagen also announced that 9,000 new jobs will be opened up with at least 1,000 of them being in the IT department in Wolfsburg alone. I wouldn't call this bad news.

I don't know why the IEEE is always such a downer about employment, but this article is stretching it the furthest I've ever seen. VW layoffs, especially if they come in the form of factory reductions / closures, could hardly be counted as 'tech industry'. Then, the actual layoffs that they tabulated at bottom of article are all significantly less than predicted. I assume it's tied to their anti-H1B lobbying, but it's getting pathetic.

It's not even layoffs. Just making use of "Altersteilzeit" (early part-time retirement) and then not filling the retired jobs.

'zeit' must roughly translate into 'time' in German, based on context. Is that correct?

danke

Ja. See also the borrowed word Zeitgeist, literally time-ghost but more accurately the 'spirit of the age'.

If only for the sake of managing the Overton window, it's good to see some counterpoint to the cries of "There's a terrible shortage of programmers [at the price point we want], we desperately need to increase [H1B quota, bootcamps, etc]!!!" that periodically bubble up from the Big Tech submarines.

Just a nitpick but I think you meant "disclosure" instead of "disclaimer". Disclaimer would be to signal you are not sure the job figures are accurate for example. Disclaimer: English isn't my first language.

You're right, thanks.

The most surprising thing to me is that Tinder has 200 employees (and plans to double it).

That sounds perfectly reasonable.

Rules of thumb: If a business has to operate 24/7 worldwide (and maybe even have office in multiple locations), it's gonna need over 100 employees.

There is no sane way around that. You don't want to be in a business with less than that many, trust me ;)

If you need 1 engineer available 24/7, you need 3 teams of 3, one each in APAC, AMER and EMEA, at minimum. You can't sustain running with less, otherwise people can't ever take vacations or get sick... if you need 2 you need at least 12 and so on.

Apparently you have never worked in a NOC?

You need one team of three for 24/7 NOC coverage, even for a worldwide customer base. Preferably four or more but three will do for a while.

Tickets are automatically generated from alerts for anything from unusual web server logs to disks filling up to network bandwidth spikes to slow SQL queries, etc. The NOC staffer attempts to resolve problems on their own, and identifies and calls the first point of contact for specific issues as necessary, following the appropriate escalation procedure.

As people get woken up in the middle of the night for their shit breaking, after a few weeks, suddenly regular problems either go away or standard procedures for fixes are documented. In a few months a staff of three can handle 90% or more of the tickets that are automatically generated.

We were doing this over 10 years ago with about 2000 servers getting traffic from 2,000 to 150,000 hits per second on Perl web apps. Honestly, nobody does anything efficiently anymore.

3 people who never get sick, never go on vacation or training, who never experience denial of physical access (or who actually live inside the NOC??)

Oh, you are talking about people who just phone other people, well you need to include the "other people" in your number.

The "other people" are just people in your company. They aren't on call, but since they own the thing that's broken they get called, it's standard escalation.

Two people on shift per weekday, three on weekends, and a non-NOC staff member works a shift on a weekend so they can cover sick time and vacation people. It's not that hard.

Your people are doing 12-hour shifts every day, and only get sick at weekends?? I call shenanigans.

They don't need to work during the day on weekdays.

I am pretty sure that people are not legally allowed to work 8 hours per day, for 7 days per week every week ;)

In the United States you can work pretty much indefinitely as long as there aren't specific regulations against it like for truck drivers.

Part time NOC gets six to twelve hour shifts as needed, and you don't need them 24 hours, you only need them during non office hours.

Weekends are the only time they're there 24 hours, and usually one engineer, developer, devops, *admin, manager, etc rotates out a shift so they have to be familiar with how the system works in case someone gets sick or takes vacation.

I know it's pushing it, but couldn't one go w/ 1 team of 5 (probably 6 for minimal downtime/buffer?) in NA to cover 24/7?

Making people operate against circadian rhythm is a hard sell. Google advocates against that in SRE book.

I once visited a Ford factory in England where the manager told us the night shift workers were paid very well (more than London front office in their first two years at Goldman Sachs) because their life expectancy might be shortened by as much as 20 years.

Ah. I did not know that.

When I was growing up, there was a 24/7 coal-mine near-by and everyone was on two-week rotations for their shift. Which (naturally) sucked. Eternal jet-lag. I thought that letting people simple pick their preferred, and stick to it would solve the suckiness...

WhatsApp was operating with 650m MAUs, 24/7, and was purchased for $19 billion.

How many employees did it have? 55.

Just because it's possible doesn't mean it's a good idea ;)

They were acquired for 19 billion dollars, so they were very obviously doing things right. Your condescending snark seems misplaced.

Maybe the fact that WhatsApp was colossally successful, more so than nearly any other startup -- this was the largest ever acquisition of a venture-backed company -- should get you to update your priors on what kind of scaling practice is a "good idea" and what isn't.

If you don't mind, I'd rather give a different view of WhatsApp and on-call.

It quickly turns out that WhatsApp could have a nice exit, so it made sense for some employees to sacrifice a bit of work-life balance, instead of looking for another job.

Your mileage may vary depending on "How many direct phone calls from customers does your company get when the service is unavailable for 10 minutes? and how much money is lost?" We don't have this data on WhatsApp.

Is there data on what the work-life balance at WhatsApp was like, pre-acquisition?

Not that I know of.

Do you have experience in 50 people startup growing like mad and going worldwide? I've been there and I've seen how bad it can be for people responsible for the critical pieces of the tech. WhatsApp is no magic. Lots of hard work and elbow grease.

WhatsApp is not and never was mission critical.

We're talking about Tinder, though.

I don't understand your comment.

Dating apps are full social networks too.

Complete with fake information and scams!
