zachrose··on Compact nuclear fusion reactor is 'very likely to work,' studies suggest
I’m also a layperson and also a fan of the 7-X, almost on purely aesthetic grounds. The plasma shape is a beautiful twisted loop, the magnets resemble a French crueler, and with the shielding and instrumentation it has all the charm of a steampunk time machine
zachrose··on Neue Haas Grotesk (2011)
There are a lot of different things to be interested in. At one end visual/graphic design is interesting because, like engineering, it's seeking optimum performance among constraints. Neue Hass Grotesk might technically "outperform" other specific fonts in specific contexts, enabling you to find, say, a restroom at the airport faster and with less effort than if the sign were in Fraktur.

On another end of it, there's the recognition that what often starts off as efficient or economical in one context will form a cultural symbiosis with that context, carrying it around for decades or centuries to follow. That's why Cooper Black might remind you of cheerful commercialism from the 70s, but it also explains how seeing Eurostyle on a fried chicken menu will give you a very specific idea about how much you'll be paying and what the condiments will be like.

In between, there's "crazy lizard brain stuff" like the Bouba/kiki effect: https://en.wikipedia.org/wiki/Bouba/kiki_effect

zachrose··on How to properly manage SSH keys for server access
When you’re tailing logs on a server there’s still a “logging system“ (your ssh connection, tail -f, a disk with finite space) that can still “fail”. Probably in either case you’d work to fix logging and you’d hope that the system is simple enough to fix.
zachrose··on The Endless Frontier Act
It seems to me as if all the economic criticisms of grant writing and funding committees (it's rent seeking that can destroy value, it distracts people who actually know science, it makes short term bets, it encourages fashions) could just as easily apply to venture capital. What's really different?
zachrose··on Meeting everyone on a new team
> With a team of ~50, that’s a lot of hours, and I was also working four days a week so each meeting takes up a greater proportion of time.

At thirty minutes a pop these meetings come out to 25 hours. That does not strike me as “a lot of hours” given that this is talking to everyone who works in your department. Put another way is like a sanity check on the biggest and most important category of your department’s budget, at roughly 1% of your annual time.

zachrose··on The Disinvitation

I object to using the notion of a "6X difference in murderer density" among Black men as a reason why police are justified in racial profiling.

But I also object to the extremely smug and faux-engineer-rationality of "This does not appear to be racism [...] It looks more like math."

If we're expecting Uncle Bob to be just some guy on Twitter I would write him off as a simple fool. If we're expecting Uncle Bob to be a thought leader in a consequential professional field requiring deep analysis and sound judgement, that's something else.

zachrose··on Annoying website features I face as a blind person
This post and the above comment prompted me to add alt text for an image on a landing page I’m working on.

Whether an image is decorative or not is a complex question that probably hinges on a lot of modernist ideology about the role of ornament[1].

A more functional approach is ask why the image is there. If it’s setting a mood, describe the image with words that evoke that mood.

In my case, the image was an illustration that I’d written off as not interesting to a blind person. But in putting forth the effort to “read” the image I realized it depicted our target demographic using our product in a fantasy setting, which is much more fun to describe than it appeared at first glance.

zachrose··on Universal Paperclips
One thing that's funny to me about this game is that it the classic "hello world" for the Elm architecture is a button that increments a number[1]. It's not hard to imagine that something like this could've started with that and just kept running with it.

A unit value is a value in the unit interval.
zachrose··on How I built a keyboard/video/mouse switch for my two 4k monitors
Definitely didn't imagine that KVM switches could actually be that good when I asked the question. (I've obviously never used one.) Thanks!
zachrose··on How I built a keyboard/video/mouse switch for my two 4k monitors
Thanks everyone!
zachrose··on How I built a keyboard/video/mouse switch for my two 4k monitors
Would somebody like to help me understand why KVM switches are so sophisticated? A DisplayPort cable has 20 pins, so why can't it just be a 20 pole switch? (Or 30 pole for two USBs and a headphone jack, etc.)
zachrose··on Ninth Circuit rules NSA's bulk collection of Americans' call records was illegal
> The US incarceration rate is at a 20 year low and keeps falling.

Technically true, but man oh man do we have a ways to go before the war on drugs is mitigated[1]. Based on the trend of the last ~10 years, we're due to reach 1980 levels of prison population in the 23rd century[2].

zachrose··on A manager’s essential guide to holding regular check-ins
> For example while it talks about employee engagement it never defines the exact meaning. While it quotes some Gallup stats on how said engagement rose for companies initiating some measures it fails to exactly describe the change (before and after state).

I feel like this has less to do with this one article specifically and more that Gallup/HBR skew these studies towards kinds of work where these numbers easy to observe, or are at least amenable to some kind of measurement. The GE study article[1] seems to support it's claim with a performance/cost engineering outcome, some business process metric whose value is left unspecified, and some sort of vague organizational change.

I'm curious if there are more rigorous or at least modest methods behind these kinds of numbers. Obviously HBR isn't going to delve into the model for their casual article, but I assume that academics at Harvard Business School do?

zachrose··on Significant JavaScript projects from 2006 to 2020
Backbone especially because it seemed so obvious to so many people that there needed to be an object-oriented "MVC" framework in the browser, and only over 5-10 years of experiencing the sharp edges and missing pieces did unorthodox alternatives (Flux etc) seem interesting.
zachrose··on Two Features of JavaScript that you might not know
I was expecting this to be about object literal setters (and getters):

  const language = {
    set current(name) {
      this.log.push(name);
    },
    log: []
  };
Supported by browsers for fifteen years now.
zachrose··on Coca-Cola paid scientists to downplay how sweet drinks fueled the obesity crisis
Alternative perspective: World of Coke sucks. It’s one of those one-way guided museums like the creationist museum in Kentucky, and contains nothing you couldn’t get out of a Wikipedia article or two.
zachrose··on The UX of Lego Interface Panels
To me that axis seems more legible-illegible than organized-chaotic. The panels on the top of the chart "read" as buttons and levers and things I'm already familiar with. The panels at the bottom have oddly particular layouts that don't seem familiar.

zachrose··on T-Mobile: Are you blocking specific words and suspending accounts?
What is it that can't be reached from Twilio? Carrier short codes?
zachrose··on T-Mobile: Are you blocking specific words and suspending accounts?
I’ve been developing SMS chatbots and using my T-Mobile phone for testing. They will also drop messages that contain URLs, although the rules for which TLDs are allowed are hard to reverse engineer, much less rationalize. Last I remember, .club URLs are blocked, .com is allowed, and bit.ly is allowed.
zachrose··on Nubank acquires Cognitect
Let’s say the company has four databases and 500 technical employees. That could get you to 2k personal development instances. Take your non-development instances and multiple for failover, blue-green deployments, multiple data centers. It doesn’t necessarily sound nice but it’s conceivable.
zachrose··on Systems Design for Advanced Beginners
> Does working at bigger companies actually give you experience with this?

If you can find someone who needs something for their business or organization, you'll learn a lot of this by working backwards from what they need and building it. So I would suggest the opposite: the smaller the organization the more you can jump around and set up the basics of all these things.

zachrose··on You've only added two lines – why did that take two days?
I sometimes look at small mass-produced plastic items and marvel at how hard it would be to make one from scratch. If you showed me, say, a fluted plastic bottle of wite-out with a screw-on cap, I would have to assume you had a very expensive operation up and running that was already churning these out.

In software we can put a few shapes on a screen in just the right context and people will believe there's an operation as sophisticated as the wite-out bottle factory behind it.

zachrose··on Ask HN: What's the worst piece of software you use everyday?
Google? It captures me with its convenience and illusion of transparency but is probably also selling a window into my deepest curiosities.

zachrose··on 1:60 scale Boeing 777 made from manila folders
Yes, I’m regards to what gets produced there’s an awful lot of beautiful art these days.

There is also a line of criticism that the institutions of fine art (education, galleries, museums, grants, etc) have, in the last few decades, distorted their previous value system of beauty (complex as it is) to focus on more conceptual and academic issues.

Check out Alone in the Wilderness by Dick Proenneke. In the late 1960s he filmed himself building a cabin in Alaska and wrote a journal, which his brother later made into a film. Most or all of the film is on YouTube.

zachrose··on Your Career in Computer Programming (2015)
Not the question you're asking, but it's always been interesting to me how fibers and written language are intertwined. We talk about strings of characters. Text and textile come from the same word.
zachrose··on Breonna Taylor case: Louisville police nearly blank incident report
Not only was this a no-knock warrant in a country full of guns, but it was also executed by plainclothes police. Figure out how that’s supposed to work.
