“App translocation”

When applications are in “quarantine” on OSX after being downloaded, they are run in a kind of sandbox; they’re “translocated”. You don’t really see this, but weird things then happen. For instance, Little Snitch won’t let you create “forever” rules on the fly, claiming your app isn’t in “/Applications”, which it clearly is if you check in Finder.

The problem is that the extended quarantine attribute is set, and needs to be reset (at least if you trust the application). Too bad Apple didn’t provide a GUI way of doing that, so here goes the magic incantation (assuming WebStorm is the problem in the example):

First check if the attribute is set:

xattr /Applications/Webstorm.app/
com.apple.quarantine

Then if you see that it is, reset it:

xattr -d com.apple.quarantine /Applications/Webstorm.app/

…and there you go. Life is good again.

 

The benefit of quality

35 years ago, I bought a Fluke 77 multimeter (series I), which was pretty expensive by the standards of the day. I’ve used it with moderate intensity since then, changing the battery every couple of years, but not having it repaired or calibrated. I never had anything to calibrate it against, anyway.

That includes Trump himself

A number of tech companies have filed an amicus brief in a suit against Trump’s executive order:

“Immigrants or their children founded more than 200 of the companies on the Fortune 500 list, including Apple, Kraft, Ford, General Electric, AT&T, Google, McDonald’s, Boeing, and Disney,” it said. The briefing also notes prominent immigrant and refugee writers, scholars and Nobel Laureates.

Now, that actually includes Trump himself. His mother and all his grandparents were immigrants.

(I’m talking about “immigrants or their children”, not “scholars and Nobel Laureates”, obviously.)

Walleräng M.01

After pining for it for half a year, I finally got my courage (and credit cards) together and bought the Walleräng M.01 electric bike (the 2017 model; yes, even bikes have model years now). The closest store carrying it is almost a 100 km away, but that’s ok. They only had one, but that’s ok, too. The price is a hefty 31,900 SEK (around $3,400), but considering the build quality and the components, it’s not remarkably high. We’re not in eye-watering territory, at least.

That’s a big stack

I’ve been plowing through all kinds of tutorials and books so that I can build a working stack of tools and libraries for doing javascript development. Boy, is that extensive and complicated. This is how far I’ve gotten until now.

I have learned most of the technologies in the graph, at least superficially, and it looks like you need most of them for a fully rounded application. The world has certainly changed from back when you could learn one language, one IDE, and one platform.

Update: do read this satirical post about how it feels to learn Javascript. It’s absolutely perfect.

All that remains is the laptop

Just watched the Apple computer event and it was really boring. All they presented were Macbook Pros. No Mac Pro, no iMac, no mini, nothing. Oh, and no Apple display.

The message I got from all this, and from the connectivity on the new Macbook Pro, is that Apple thinks that the Macbook Pro, in combination with the new LG 5k displays, actually can do the job of the iMac and the Mac Pro. That you don’t really need anything else. Or rather, that they can’t be bothered with it all anymore. Even during the ostentative computer event, they couldn’t keep from gushing about the iPhone instead. They’re simply bored with computers.

The Air is clearly on it’s last leg. The cheapest Macbook will cost substantially more than the Air when it’s gone, which to me means that schools won’t be able to afford them any longer. So that leaves, what? Lenovo and Dell?

It feels like the end of an era. I wouldn’t be surprised if Microsoft is the new Apple. Just look at the Surface Studio.
