Okay, with recent goings-on, I'm feeling really gross supporting Twitter. Closing up shop here. Still on Mastodon: ruby.social/@codefolio

The Ruby world seems to have collectively decided that GraphQL needs to displace REST. The backlash is gonna be *vicious* in a couple of years when people try to scale/optimise legacy GraphQL.

You'd get to watch huge numbers of privileged folks try to find ways to weasel around whatever rules you made. Which, actually, would *still* be way better than the current way. So okay, yeah, I'm here for it.

Kicking people out of embassies is harder. Nominally the US embassy is American soil (and similarly, a German embassy in the US is considered German soil.)

Ah, so you're saying they were trying to get it up to "zombie apocalypse" proportions in the hopes of getting to something they could solve by shooting everybody.

I like how they specify that it's the responsible (ethical) AI teams all reorg'd under one exec. The irresponsible/unethical AI teams are still where they were, doing what they were doing. Which should be a joke, but in this case isn't.

Hey, folks! I'm currently available for a part-time or contract gig. I do performance, framework/metaprogramming and Ruby rescue work among others. I'm full-stack, ops-capable and language-flexible, but of course with deep Ruby experience. UK time zone. DMs are open.

My family and I (wife, three kids) were all born in California. We've left the US after finding out how many of our fellow Americans want awful things. Moved to Inverness where we get along well with the locals, the NHS and the SNP. I'm a computer programmer and work remote.

If you install the new Ruby 3.1.0 release, #YJIT is built in! Provide the --yjit command-line parameter to use it, or --jit to choose YJIT or MJIT by platform.

Ruby peeps: several big security problems found, new patched versions of all live Ruby minor versions back to 2.2 released to fix. Update your interpreter pls. Also: 2.2 is EOL after this, 2.2.10 is the *last* 2.2 security patch.

I've been working for myself for two months. I've just released a new version of Rebuilding Rails, replacing a 2.5-year-old version. There's just *so* *much* I've left undone that needs updating. Making progress, though!

How do they feel about your book with "build a harem" in the title? *That's* maybe the problem with only going for girls who don't sleep around - you're making it clear that *you* do.

Yup. But they have to go through that whole process, not just (for instance) cancel his visa and deport him.

Taking time during quarantine to study and improve your skills? Just having a hard time lately? Here's a 50% off link for Rebuilding Rails, far more than I've ever discounted before. It'll work for at least a few weeks - I haven't decided how much longer. gum.co/rebuilding_rails/coro…

Exercise: if you can save/earn fifty people 10% of their value for a year (hard, but totally possible with good infrastructure) and they all make $250k, what's that worth to your employer? Now, are larger numbers than 10% and fifty people possible? (yup)
A mid-career (~5 years in) competent performer at AppAmaGooBookSoft has a total package of ~$350k per year. There are tens of thousands of engineers there with a package closer to ~$800k.
The people getting those packages are talented, but not unachievably so. Just market rates.

One kinda shocking cool thing about the Ruby community: if all your senior folks are friendly enough, you wind up with more mentors than new devs to be mentored. Consistently. For years.

In addition to all of this (and I agree)... Nearly *every* expert You've Heard Of isn't because they're the best. It's because they've put all that work into Being Heard Of. (Me too - I put massive work into Being Heard Of.)

Find or buy a notebook. Bring a few pens with you. Keep a "TODO" page and a "questions" page. Write on them when adding a TODO item or a question. You will finish your first day with a *lot* on both, and with a notebook you won't lose items to normal human memory.

It's the same way that, say, Cambridge Analytica works. If you take a chunk of stuff you're 90%-ish sure of and take a best guess, mostly that IDs people closely enough that you know which US citizen they are. Which is to say, yes, it's incredible and terrifying.
26
Yeah. Serious folks who use Bitcoin for normal transactions (admittedly, a small group) have always understood crypto-anything has to be reported, just as though you took payment in gold/rupees/chickens. "Not dollars" does not mean "not taxable."

You do not need to be a UK resident and are encouraged to apply regardless of familiarity with games and games writing. More info here:

Scotland, and especially Northern Scotland, is a beautiful place to run from climate change. The UK also has a *great* visa for self-employed technical folks, though you might be wealthy enough not to need that one. We moved to Inverness a year ago and we love it.

Got a bad network connection, like me? Remember that "git clone" is just "git init" followed by "git pull". If a clone fails it deletes all the intermediate results, but "git pull" can be failed repeatedly to get partial downloads successfully. So it's better for a big repository

It is *so freaking hard* to detach and do simple, silly fun coding stuff without feeling like it makes you dumb :-( I've been coding for over 30 years and it's *still* hard to just be like, "that's a cool silly-sounding idea, it's okay if I just try it."

Any software/tech/IT types curious about moving to the UK? I wrote a blog post about the visa I used for that. It allows self-employment, NOT company sponsored, and lasts up to five years. That's enough you could get permanent settlement. codefol.io/posts/amazing-vis…

Heh. Seems like it's the day for this question. My family and I moved to Northern Scotland about a year ago. It's a beautiful place to hide from climate-change armageddon, and the UK has a seriously good visa for self-employed technical folks.

Weird random benefit of living in the UK: different ideas of what's neutral. I ordered something and was entered to win a bespoke drinks cabinet. Wasn't opt-in, just: clearly you want a drinks cabinet. What did I order? A shoe rack. It's a lovely cabinet.

I've turned on Purchasing Power Parity for my ebooks and classes, including Rebuilding Rails (rebuilding-rails.com). I have also removed my usa-is-expensive honour-system equivalent coupon.

Making this harder: changing your claimed core responsibilities is often a management dodge when there is a *different* reason they don't want to promote you and won't say so. "Oh, you didn't do X." "You have never previously claimed X is important." "Well, uh, it is."
