Twitter endorses Nazis

Mastodon

2017-11-13T19:21:00Z

I’m using Mastodon regularly now, I’m @nelson@lgbt.io. Add me!

Mastodon is a Twitter-like social media that the cool kids started using back in April. At first blush it’s just like Twitter. You post messages about your breakfast, you follow other people to see their cat pictures, and you get a little dopamine rush from social engagement. Also maybe you share things of personal or public interest and help build an important online culture. The UI isn’t as polished and it doesn’t have as many features as Twitter, but it’s good.

If you want to start using Mastodon this beginner’s guide or the Join Mastodon site are good places to start. The key thing is you have to pick an instance to sign up on. This tool helps find instances or you can just pick the biggest instance. I picked lgbt.io because I like the idea of an LGBT identity.

Once you join you need to find people to follow. The best tool I’ve found for that is the Twitter/Mastodon bridge which helps you find your Twitter friends on Mastodon. It requires both sides opt-in and the UI is a little awkward. I also followed a lot of people from Metafilter.

I don't like the default multi-column web UI. I'm using this one column layout instead but it's not particularly easy to install. Halcyon is an alternate Mastodon web client that is a Twitter UI clone; you can use it with any Mastodon account. For iPhone apps people recommend Amaroq.

So why Mastodon? For me it’s because I’m angry with Twitter’s endorsement of Nazis and want an alternative. Also it’s fun to try something new. The big drawback is very little of my community is there. But maybe it’ll grow! Also it’s good that Mastodon is a different community than Twitter; the goal is to not replicate all the awful community mistakes Twitter made. Hopefully the abusers and Nazis and insane presidents will never join Mastodon or at least will be filtered out somehow.

The big technical difference with Mastodon is it is federated; instead of one single Mastodon server there’s separate instances that communicate with each other. For casual use the federation doesn’t matter since most everyone can talk to everyone else across instances. But in theory it allows for diverse communities with different standards. Also possibly some interesting scaling properties. I’m a little skeptical about how this will work as Mastodon grows, I don’t know that they have any magic solution to Internet abuse. But I’m excited to see someone trying something new.




German elections 2017

2017-09-25T17:26:00Z

The big surprise from the German elections was how bad Merkel and the ruling CDU did, and how well the deplorable far-right Alternative for Germany (AfD) party did.

Berlin is a lovely city, very optimistic and international. It also has little patience for AfD bullshit; I saw no AfD signs anywhere until two days before the election, and those only way up high out of reach on poles. There was a big demonstration last night in Alexanderplatz after the election; the AfD were having their party there so a few thousand Berliners turned up to, um, help them celebrate.

Some links that may be of interest

Now for the coalition negotiations. It's not clear to me if the SPD saying they won't join one with the CDU a negotiating tactic or if they mean it.

Urban Nation in Berlin

2017-09-17T18:20:00Z

A new “urban art” museum just opened in Berlin: Urban Nation. Judging by their opening weekend show it is a fantastic collection of modern street art. I put a few photos of the works I saw on Flickr.

The event had an “art mile” with some temporary sculpture installations. Also some magnificent large scale street art works on Bülowstrasse itself, hopefully those will last awhile. I particularly liked Zezão’s alien calligraphy forms. Also liked some of the wildcat street art, I think a few lesser-known artists got some unauthorized paint up.

The museum show had a really thoughtfully selected overview of the best of modern streetart. C215, Deih XLF, Dalek, the obligatory representations by Banksy and Invader and Fairey. It’s terrific a museum is collecting these from all over the world; whoever is curating seems very plugged in. I wonder who’s funding the building and collection; the website only mentions some city of Berlin funding.

Oculus Rift first impressions

2017-07-15T22:32:00Z

I got an Oculus Rift on a whim this week when they dropped the price of the bundle down to $400. This is my first experience with VR in a few years and 10+ since I last used a high quality rig. I’m impressed, the sense of being present in virtual space is incredibly compelling. But as everyone says the problem is there’s no great VR-specific content yet.

The hardware is good. Lag-free head and hand tracking. Sensor calibration is a hassle. Windows setup was remarkably painless. The touch controllers are essential. It allows you to have virtual hands. Definitely want “full room VR”: several tracking sensors and a 5x7’ clear space to walk around in. Sitting still and having the view pan is instant nausea but walking around a stationary virtual room is better. Even with the calmest software I get tired and headachy after about 30 minutes. Eyestrain maybe? VR sickness makes for a viscerally negative experience.

As for software, I’ve only played around for a few hours, so no deep opinions. Oculus’ own tutorials / demos are very good, the intro Dreamdeck demo had me shouting for joy. The best game I’ve played so far is Superhot VR; I’ve not played the normal version but the VR variant is really compelling. Subnautica made me sick in about five minutes, although it is very pretty. Thumper is pretty in 3d but I’d rather have a flat screen and excellent speakers. Google Earth VR was surprisingly disappointing; the imagery isn’t quite good enough. I haven’t tried Job Simulator 2050 yet, it’s quite popular. I’m also curious to try The Climb.

I took a quick look at the porn industry; all they’re offering is 3d videos and some minimal “fondle boobs with your glowing virtual hands” interaction, so they haven’t figured out VR apps either. The fact that "Waifu Sex Simulator" is one of the most popular apps gives you an idea of the target market.

So it’s a fun toy, but given the fatigue and lack of compelling content I’m not sure how long I’ll be using my Oculus Rift. We’ll see. What I really want is some easy way to build data visualizations in 3D, maybe using WebGL or something. I haven’t looked hard but my impression is that’s not fully baked yet.
