Istvan Soos is building a package that makes the Service Worker API more Dart-y and easy to use. Here's how you can use it to make most web apps and games work offline.

Víte, jak většina lidí v České republice podává daňové přiznání tak, že podepíši růžový formulář, který jim předpřipraví zaměstnavatel?¹ Tak ve Spojených státech tohle neplatí.

Každý, včetně zaměstnanců, si podává celé daňové přiznání sám. Většina si platí buď TurboTax² nebo jiný software na správu daní, protože vyplnit to ručně je takřka nad lidské síly. I tak nad tím lidé tráví hodiny (většina z nich tento víkend, takže je to dnes téma).

Myslím, že to je jeden z nezanedbatelných důvodů, proč američané mají ještě větší odpor k placení daní než jiné národy. Když ty peníze musíte přepočítávat sami, má to větší efekt než když tu částku jen jednou za rok někde vidíte a podškrtnete.

Pro stát by dávalo smysl podání daní zjednodušit. Jsou o to pokusy i tady v Kalifornii, ale lobby firem jako je Intuit (výrobce TurboTaxu) a H&R Block (populární alternativa) je prý příliš silná — přece jen jsou v tom miliardy dolarů ročně (TurboTax stojí každého plátce kolem $100 každý rok).

Imagine what people expect you to say. Then don't say it.

Classic rule of (speech) writing. Makes perfect sense even from the information theory standpoint. The more you deviate from the expected (Shannon entropy) the more information you provide. https://en.m.wikipedia.org/wiki/Entropy_(information_theory)

Hi Dartisans, quick question: What are some big & important developer conferences that usually happen between September and November?

Things I'm looking at:

● What types of developers does the event attract? Java devs? JavaScript devs? Systems engineers? SW architects? (Some ‘get’ Dart, Flutter and AngularDart more than others.)
● What level of developers attend? Students? Hobbyists? Professional developers? Tech leads? CTOs? CEOs? (All are important, but we want a good mix.)
● How many people attend? ~100? ~500? ~2000? 5000+?
● Does the conference normally provide videos of sessions? Streaming?

Here's what I have so far (in chronological order):

● JavaZone Norway
● StrangeLoop
● Gartner’s Symposium/ITxpo
● Mobile and Disruptive Technology Summit (India)
● JAX (London)
● Codemotion Berlin
● ReactiveConf (Bratislava)
● Devoxx Belgium
● QCon (San Francisco)
● Øredev (Malmo, Sweden)

I'm not saying we'll be on all those events. I just want to have a comprehensive list, and this is where simple Google/Eventbrite/... searches got me.

A new study¹ explores ways of preventing people from believing bullshit like ‘Atlantis existed’ or ‘9/11 was an inside job’. (Also known as: critical thinking.)

The study was performed on 117 students in 3 groups:

● group A was taught statistics and study design
● group B and C were enrolled in two slightly different courses on historical frauds and mysteries

Group A was the control group. Students in groups B and C were, among other things, taught how to identify logical fallacies, like non sequiturs.²

All students were asked about their beliefs about different topics, like the aforementioned Atlantis or 9/11 conspiracy, before and after the semester.

Unsuprisingly (for me, at least), students in groups B and C believed less of the fake stuff after the semester (their critical thinking improved). Surprisingly (for me), the students that were told statistics and study design didn't improve at all.

The point of the study: you have to be intentional in teaching people about logical fallacies if you want them to stop believing bullshit. Critical thinking is a tool that many people don't possess, but it can be taught effectively.

Article via +Rhys Taylor and https://phys.org/news/2017-03-critical-humanities-belief-pseudoscience.html.

I'll use this opportunity to share some good resources about logical fallacies (in descending level of completeness, and increasing level of approachability):

http://www.cracked.com/article_17142_5-ways-common-sense-lies-to-you-everyday.html

A lot of the ‘fake news’ believability hinges on you not being aware of these fallacies. And, let's be honest: it's not just fake news. It's also marketing and politics and sales.
