On behalf of Piotr

It is with great sadness that I inform of the passing of Piotr on July 29th, after his long fight with cancer. He was a great man, great engineer, a wonderful husband, father, brother and son. A dedicated Ruby community member. He will be sincerely missed

Piotr's wife, Monika

Please consider me on a coding/work hiatus at least till the end of September, due to health reasons. 🫠

I was heavily offlined the last few weeks, so I’ll have Opinions™ more end-of-August at best! But my Vim clumsiness finally pays back, the basic bindings are the most I ever learnt. 😇

... and this is why I don't like to talk to journalists. I made an exception for The Economist: sent over 7 pages of details on the comp landscape and told them they can use it, plus quote from @pragmaticengineer.com as long as they link it.

They used my chart, redrew it as their own, did not link.

It's happened: the trimodal nature of software engineering compensation made it to the Economist!

Disappointingly though, they did not link to the original article (they never do AFAIK), they redraw the image, and do not call it trimodal. Feels like "ripping off" my research, not gonna lie.

GitHub managed to make the files changed tab slower than it was before. This is astoundingly bad. 6 seconds to load the top of the page. 10 seconds to register hovering over a link. If you switch away to another tab and switch back, you need to wait about 2 seconds for it to render again. 🧵

Reviewing large pull requests just got a major upgrade. Try out our faster, more accessible Files changed tab—now in public preview.

Click “✨Try the new experience” in the upper-right corner of any pull request. (You can switch back at any time!)

Right, apologies. 🤦‍♂️

You can mutate the array because you have access to the passed-by-value pointer to it (`a`), but you can’t repoint it (this is why `a += [3]` doesn’t change the caller’s variable).

This is also why you can’t mutate immediates.

Piotr Szotkowski 🛡️ @chastell.net · Jul 1

This is because `a += [3]` is syntactic sugar for `a = a + [3]` – you are not modifying `a`, you create a new local `a` from the passed-in `a`.

`a.push(3)` is a call on the original `a` that modifies it.

(Ruby is pass-by-reference except some objects are immediates, like small integers… 😱)

Can they do Polishness next? My paternal-paternal great-grandpa was Czech, my maternal-paternal one was Silesian, the majority of them identified as Poles probably, keine Ahnung – Poland didn’t exist for 123 years (that’s five generations?).

And then what does it mean to be Catalonian.

Neil Brown neil@mastodon.neilzone.co.uk:

Sometimes, I receive questions which leave both me, and the person asking, bamboozled.

> Your website loads so quickly! What CDN do you use?

There is no CDN. It is just really small and simple, mostly text.

> Sure, but is that Cloudflare, or...?

None. It is a tiny website, just a few kilobytes per page, on a tiny server, at my home, connected to the Internet via my ISP, Andrews & Arnold.

> But are you / they in the cloud?

No. The webserver is in Newbury, in my garage.

> Neil, please can you pass my questions to your technical person? I don't think you understand, your website cannot be in your home. It must be in the cloud or have a CDN.

The death toll of Israel’s ongoing genocide in Gaza is now estimated at 100,000

The list is 1,227 pages long.

The first 11 pages are names of babies dead before the age of 6 months.

The first 381 pages are all children.

archive.is/2025.06.28-0...

On Monday of this week, Hamas' Health Ministry in the Gaza Strip published an updated list of those killed in the war, a 1,227-page chart, arranged from youngest to oldest. The Arabic-language document includes the deceased person's full name, the names of the father and grandfather, date of birth and ID number.
Unlike previous lists, this compilation notes the precise age of children who were under the age of one year when they were killed. Mahmoud al-Maranakh and seven more children died on the same day they were born. Four more children were killed on the day after they entered the world, five others lived to the age of two days. Not until page 11, following 486 names, does the name appear of the first child who was more than six months old when he was killed.

Tried to use Gemini to fix a bug in Ruby. It made a change that caused Ruby segv, told me it's too dangerous to continue, and then gave me instructions as to how to report the bug 🤣
