Quick thoughts on the Nintendo NX

posted this on and tagged it with Nintendo Nintendo NX

A handheld console that can be connected to a TV seems like the right way to go, at least in my opinion. As previously discussion on this blog I love my 3DS but there are countless times that I’ve wished that it supported AirPlay or something similar that allowed me to put the video up on my TV.

Nintendo has been playing the game its own way, totally detached from the other console manufacturers spec race, for a long time. Maybe this is the way for them to go.

How I manage what goes into my news rivers

posted this on and tagged it with River of News WordPress

Almost a year ago I wrote about WordPress’ Link Manager. It’s an old feature of WP that seems to get very little use these days. But it is a way to collect links to websites and, this is the important part, their corresponding RSS/Atom feeds, and get an OPML file os the websites in question.

Collected links can be put in categories and every category has its own OPML. You can find the OPML for all my links here.

OPML is one of the file formats that can feed a river in River 5. As far as I know the OPML that River 5 reads needs to be in the lists folder in your River 5 installation, so at first glance that seems to rule out using WordPress’ OPML feature.

The not so secret sauce that makes it work is the ”include” node in OPML. In my lists folder I have and OPML file for each and every river I want River 5 to generate. Each of those files contain a single <outline> node that links to the corresponding category among my WP links.

For example, my ”Everything feed”:

This tells River 5 to include everything it finds at the URL http://blog.henrikcarlsson.se/wp-links-opml.php which, as I just mentioned, is the full list of links that I collect in my sites link manager.

So whenever I want to add or remove a link (site/blog/etc) I just use WordPress’ link manager. That makes it very simple to add and remove stuff and therefore I’m more likely to try to add new sites to the mix and see if they add to my satisfaction or not.

Keeping up with the news using River 5

posted this on and tagged it with River of News Twitter

River 5 has been running on one of my servers now for about twenty-four hours and so far things seem to work perfectly. Order is restored and I feel connected with the news again.

River 5 is a feed reader that generate rivers of news. A river of news is a way of displaying items of feeds that presents the items in one or more feeds as a reverse-chronological list with a headline (if present), short text and a link to the original post. It’s very similar to the Twitter timeline. The main difference is that news rivers uses RSS and Atom feeds for their content, not a proprietary plattform, hence they are part of the open web.

You can see and use my rivers in the native views that’s included with River 5 here, or you can checkout my own simplified version of the viewer, that’s more optimized for my smartphone.1

As I’ve mentioned before, I’m currently not using Twitter. I stopped mostly because I don’t like the debate-climate there. The limitations of Twitter that once made it interesting has turned it into a great megaphone for anti-intellectualism and it effects all of us when we’re using it. However, I did started to feel disconnected from the news of the world when my old, River 4-based, rivers stopped working right around the time i quit Twitter.

So I rebooted using River 5 and now I feel connected again. The river is basically my timeline. I decide what goes into it, the same way I did on Twitter. The difference is that the articles on news sites and the posts on people’s blogs are more thought-through than the quips we throw around Twitter. The same goes for the microblogs I include in the rivers. Even though they are basically the same as tweets, I don’t think they are as hamstrung by the format.


  1. This is very much a work in progress, but it’s the way I’m currently getting most news. 

The basic building blocks of Twitter

posted this article on and tagged it with Microblogging River of News Snippets.today The open web

At its core, Twitter is just three fairly simple things.

  1. A simple way to post short status updates.
  2. A list of people who’s post you follow.
  3. A timeline that mashes the posts from those people together into one stream.

Every piece of the puzzle was there long before Twitter. For posting we had, and still have, blogs. For following we have things like blogrolls, remember those? And the timeline is just a river style feed reader.

The indie web movement are trying to recreate this, but I think what they/we lack is a turn-key solution for new users to get all this. The pieces are there, but they need to be combined.

Today I learned more about an upcoming service that I’ve been keeping my eye on for some time, that will bring these pieces together in what looks like a great way. Exciting times!

Roland TR-707

Today I got a Roland TR-707 ”Rhytm Composer” from my dad. (In exchange, he got my SE Electronics Reflexion Filter. Each of us think we made the better part of the deal.)

A quick phone snap of the Roland TR-707

Unfortunately the first attempt at turning the device on failed. Dad did not have an external PSU for it, so I had to look through my own boxes of PSUs.

The 707 has a battery compartment that holds two AA batteries, but from what I’ve been able to gather from the user manual of the device as well as from the internet in general, these are only to power the machines memory when disconnected from a regular power source. It’s main power comes from the DC input that expects 12 V DC, center negative. I found an adapter among my spares that matched the specs but it didn’t connect properly. It seems like something i stuck inside the DC In jack.

When checking it out and while searching for information on the PSU (the center negative thing was not evident from the machine itself) I realized that my particular unit has an extra jack next to the power switch. The jack seems to be a 3.5 mm mono jack and from the labeling on a piece of tape on top of the machine, this is an alternative power jack.

To confirm this I decided to open up the 707. Doing so is very straight forward. Just turn it so the bottom faces up and unscrew seven philips screws. Once it poped open I could see wiring from the 3.5 mm jack to the circuit board connection of the regular power jack, so it seems like this indeed is an alternative power jack. Unfortunately, when I opened it I managed to sever the red wire that connects the battery pack to the circuit board, so I’ve busted the memory for now. I don’t have a soldering iron at home so I can’t fix it right now, but I don’t see how fixing it can be a problem.

(Left to right) 1. The regular DC in. 2. Power switch. 3. The tacked-on, alternate DC input.

I put the machine back together and started searching for a 12 V DC power supply with a 3.5 mm plug and realized that my guitar pedal PSU (the T-Rex Fuel Tank) actually have that feature. So I plugged it in and tried to power on the device, but sadly no luck.

At this time I’m not sure what the problem is and since I don’t have neither a soldering iron nor a multimeter available at home, I’ll have to put this off to another day. I’ll keep blogging about my way to make it functional again.

An iPhone without a headphone jack

posted this on and tagged it with Apple Music production Open standards

There are strong rumors flying around the internet saying that the next iPhone will lack a traditional 3.5 mm headphone jack. If that is the case I will be sad. If Apple does this and keeps it up in the future, my next phone will likely be an iPhone SE (that has a headphone jack) and thereafter I’ll switch away from Apple. I don’t want to do that and since so far this is only a rumor, I don’t need to worry about it today.

Among the articles I’ve read on the topic, I think Jason Snell’s ”Searching for a good reason to remove the headphone jack” on Six Colors is the best.

I’d like to add extra emphasize to the way a (so far hypothetical) removal of the 3.5 mm jack would impact the audio and music business in a bad way. In recording studios all over the world, there are people connecting their phones to big, expensive mixing consoles. We do this for instance to be able to listen to reference material when making a recording. Same is true in the live sound world. In PAs everywhere there are phones connected to the Front-of-House mixers being used to play music that the engineer needs to calibrate the PA properly. So far this has been pretty straight forward, since every phone, every tablet and every laptop that I know of has a 3.5 mm jack.

So regardless of what (brand of) device people might use in your studio/PA, you can count on the 3.5 mm tele plug to be the simplest solution.

If Apple removes the headphone jack we will have a more stressful work-environment, with more crap to keep track of and more adapters to loose.

So please, say it isn’t so.

I’m taking a break from Twitter

posted this on and tagged it with Social Media

I’ve felt for a while now that it is time for me to step away from Twitter, maybe not forever but at least for a few months.

I don’t like what Twitter does to me. I obsessively check it at every available moment. That might in it self not be a problem, but the stuff that I read there doesn’t make me happy, doesn’t stimulate me and doesn’t in any way make my life better. It just makes me angry. I get angry about the things that I read and then I feel a need to make angry or sarcastic remarks about it and thereby feeding back into the toxic hell-stew.

I seem like a really grumpy guy on Twitter, and that is a role I’m not that comfortable to play at the moment. Therefore I deleted all Twitter apps on my phone last Thursday (June 30th).

The fact that I’ve been off Twitter for a few days might seem strange, particularly since you most likely are reading this because you followed a link on Twitter, posted days after June 30th. That’s because I have a cross-posting plugin on my blog. That plugin will continue to cross-post everything I blog to Twitter as well. Through the magic of Bridy, your replies to my posts will also keep being backfed to the blog. But I will not read my Twitter timeline at all during this break.

Instead, I will read more stuff via RSS and I will try to blog more and about more diverse things. I also want to post more microcasts. If I can get a reliable cross-posting mechanism working I’ll probably also get back into Anchor. You can also still find me on Instagram, at least for now.

Three hours later, trying to figure out how (if even possible) to add a ’Action Segue: Show’ from a cell to a View Controller …

Christoffer Vilander (@c_vilander) on Twitter

Om jag förstår det du försöker göra rätt, och om jag minns rätt vilket inte är någon garanti, så ska du skapa en segue i dina storyboards från din UITableView till vyn som du vill visa. (Ctrl-dra från TableView till målet.) Sen ger din segue en ”identifier”.

Sen har jag inte koll på hur det ska se ut i Swift men i Objective-C så hade jag gjort så här i TableViewController.m:

Hoppas att det var svar på din fråga och att det hjälper.

Ikväll började jag titta på Jessica Jones på Netflix. Har inte vetat nåt om vad det är eller vad jag ska förvänta mig men eftersom det sagts så mycket positivt om det så blev jag nyfiken.
Efter ett avsnitt tycker jag att det verkar vara riktigt bra. Spännande, coolt och till och med gripande.

My frustration with Twitter, succinctly summarized by Dave Winer (and than commented way too rambly by me)

posted this on and tagged it with Dave Winer River of News Silos The open web Twitter

Yesterday Dave Winer made a harsh comment regarding twitter.

Everyone: When you ask ”Isn’t that what Twitter already does?” the answer is no. Twitter does nothing well because of the 140-char limit.

You might even say Twitter does nothing. The Seinfeld of social networks.The province of snorts and gusts. Miscreant sarcasm and trollery.

– Dave Winer on Twitter, 2016-05-13. (first paragraph, second paragraph)

At first this might sound like an oversimplification but it resonated with me. Twitter is making me increasingly frustrated these days. The 140 character limit might, might, have been a good thing to differentiate it at first but today I think that it’s one of the core problems of the service.

A hundred-and-forty character limit is actively harming nuanced discussions. Once you start tweeting directly to one person it gets even worse since precious characters are eaten up by the username of that person. So instead of discussion we get people screaming simplified messages into the void, we get Trump, we get people calling someone who tries to argue for something a racist, or a sexist, or a social justice warrior, a communist, a fascist, etc. Whatever name you find is properly insulting you use to smear the those who seems to not agree with you. When there’s not enough room to question or to debate you get name-calling.

I’m guilty of this as well. I’m also guilty of not speaking up and not questioning in a lot of cases. There have been so many times that I thought of something that I wanted to express, so many times that I wanted to ask follow-up questions to someone who wrote something that I didn’t agree with and so many of those times I chose not to. Because I couldn’t fit it within the limits of twitter without botching the message completely. So instead I kept shut.

So why do I keep using twitter? Probably because so many of my friends and people whose opinions I care about are there, and so much of the news that I read comes to me this way.

Fortunately the latter obstacle is not that much of a problem. I’m still an avid RSS user and I could replace a lot of my news sources on Twitter with various RSS feeds and readers. In part I am doing that already since I’ve more or less unfollowed every single account tweeting about Swedish politics or Swedish news. Instead I keep the RSS feed of some Swedish newspapers in my river of news.

Same thing goes for a lot of tech news as well.

The first problem, that so many of my friends and people who’s voices I care about is on Twitter is a bigger issue. I am actually after all these years contemplating joining Facebook. Maybe that would help me to keep up with my friends. In a way, I think it would be better for this than Twitter is.

As for the people who I’m not a real-life friend, who might not even follow and/or be interested in me, with but whose opinions matter to me, I think all of us – everyone who’s expressing strong opinions on the internet – should be better at expressing us on our own publishing space as well. More blogs, more of the indieweb.

This post got a lot more rambly than I planned. I’d actually only planned to quote Dave and to leave a sentence or two as a comment but things doesn’t always turn out the way we’ve planned.

So I have no great way of ending the post. No call to action for you, the reader or for myself. I guess I’ll get back on this topic.
