If you've ever wondered why everyone says "therapy is great, you should get a therapist" and yet it's ridiculously hard to actually do this, I can discuss it at length...

mabcat··on The Dutch Reach: Clever Workaround to Keep Cyclists from Getting “Doored”
In my experience taking the lane stops people from assuming that they have space to pass except by changing lanes. Car drivers mostly take their cues from the cyclist. If you're cycling in the gutter it signals for car drivers to try to overtake you in the same lane. Why would you be in the gutter, except to yield the rest of your lane to cars?

There's not space for a car and a bicycle in the same lane. A car will always have to at least partially change lanes to overtake safely. You're better off being 2/3 of a lane over, so your head is in the same position as every other driver, and car drivers change lanes completely to pass as they would for any other vehicle.

mabcat··on Machine Learning 101: An Intro to Utilizing Decision Trees
Features is another term for inputs, variables, etc. It has a connotation of being recognisable as a property of the thing being modeled, that you might have cleaned up from the raw data.
mabcat··on Fasting triggers stem cell regeneration of damaged, old immune system (2014)
Tim Ferriss has poked at the positive effects of intermittent fasting on cancer/health/longevity a bit. I found this interview with Dominic D'Agostino very informative: http://fourhourworkweek.com/2015/11/03/dominic-dagostino/

mabcat··on The Correct Way to Validate Email Addresses
As in bloggsfamily@localisp.net.au that both parents and all the younger sprogs share. Still common as anything.
mabcat··on Tricks to Monetize Your Side Projects
It does allow you more flexibility with pricing. As an example, iStock sell photos that cost 1 credit or 3 credits depending on how fancy they are. But the credits cost a variable amount depending on whether you bought a few credits or hundreds. So they can offer a tiered a la carte pricing structure that also has bulk discounts. Hard to tick all those boxes without credits.

Same for me when removing a device. Meanwhile, removing a linked app works just as you'd expect
mabcat··on July was the hottest month ever recorded, according to Nasa
This is a "just noticeable difference", stacks of research on it. In some situations the JND for temperature is as small as 0.02 degC. Whereas if I sneak the room temperature up over the course of about 10 minutes you may not notice a 5 degC change. From one summer to another? I'm going to speculate that people have no idea whether it was cooler last year.
mabcat··on Registered Replication Report – Facial Feedback Hypothesis [pdf]
By the way, "holding a pen in your mouth makes you feel smiley" is definitely in psych 101 courses, and social 201, and also showed up in cognition 301 if memory serves.
mabcat··on Registered Replication Report – Facial Feedback Hypothesis [pdf]
I helped run a clinical trial for an antidepressant one time. It was a double-blind randomised within-subjects-replicated crossover design. All that control was complicated, time consuming and very expensive. Only the hospital pharmacy knew whether participants were in treatment or placebo for a given session, and we never met the pharmacist, just received an orange vial. But we're pretty sure information still leaked, because drugs have side-effects. There's nothing to be done about this. Use an active placebo, you might say, but now you've added "get ethics approval to administer a nauseating placebo" to your 9-month-long ethics todo list. And then your placebo is worse than your active and the whole study is screwed because everyone spewed up in the MRI. Meatbags are tricky indeed.

mabcat··on Uber to Sell China Business to Rival Didi After Losing Billions
Don't fly to Sydney then! I don't know what devil-deal was done, but the app won't allow you to summon an UberX inside the airport boundaries.
mabcat··on LastPass autofill exploit
I switched to 1Password after Lastpass got acquired. I obviously have no special knowledge how secure it is but it's serving me well. OSX browser integration excellent, iOS integration mediocre.
mabcat··on Let's Encrypt now fully supports IPv6
That curl command doesn't connect on my OSX El Capitan.
mabcat··on Why do so few humans kill themselves?
I think your comment has blurred some distinctions that the post takes care to pull apart. Every human inevitably suffers and has reason to commit suicide, so why don't they all want to? Many more people want to commit suicide than do commit suicide, so why is that?

The reasons that you posited for Alice not killing herself were among many mentioned in the post.

mabcat··on The takeover: how police ended up running a paedophile site
I think you will find, depending on where you live, that personality rights are often much narrower than that. In general the rights stem from protections against passing off or unauthorised use in an advertising context. In Australia and in most US states personality rights wouldn't have much to say about pornography, far as I know.
mabcat··on Ask HN: What did your 'Show HN' project turn into?
I needed something like this literally last night, glad to find it now.

If you want it to be more widely used, maybe it could use some SEO or marketing love? You don't seem to be on page 1 for company name generator, business name generator, name generator, etc., and you deserve to be. Get an h1 tag, get a few blogs to list you on their "top 5 web 2.0 name generators" articles.

mabcat··on Facebook's Filter Bubble Is Getting Worse
> Now as to whether people actually want this, I don't think they do.

They do. Surely you've seen statuses to the effect of "any one of my friends who supports [belief] can just go and unfriend me so I don't have to unfriend you". Certainly I have friends who are so stridently in support of things I think are unethical/illogical/foolish that I've unfollowed them because their posts make my head hurt. If it weren't for the bubble there'd be a lot more of that.

mabcat··on What to do with the “rm -rf” hoax question
That is a great article. I just strictified the cheeky shell scripts that automate deployment of my current project.
mabcat··on When doctors, psychologists, and drug makers can't rely on each other's research
Unfortunately you have a fundamental misunderstanding of health experimental design. Double-blind means that neither the participants nor the experimenters know which participant is allocated to which group. It doesn't say anything about how many groups there are or what is done to each group. I haven't heard of Dr Bredesen, but they could certainly run a double-blind study to validate their treatment regime. Treatments that haven't been validated in this way have a high risk of being ineffective but appearing effective due to experimenter error, placebo effect, demand characteristics, etc. Requiring convincing evidence in the form of a double-blind trial isn't purism, it's sensible caution based on experience.

edit: you're also on shaky ground statistically. There's a rule of thumb that if interactions between several variables are present in a treatment effect, 70% of that effect will show up on the individual variables (as main effects). It's very unlikely that there exists a treatment where all the effect is on a 35-variable interaction and none of the effect is visible when looking at each variable singly.

mabcat··on Why can't China make a good ballpoint pen?
The example in the article is that export pens get twice as much QA time (two test clicks instead of one test click) which involves twice the QA labour cost as for domestic-market pens. Same components, different process.

More generally I've had products manufactured in China for sale in Australia, and they certainly had more expensive parts than products assembled on the same line for sale into China. Never in a million years would the domestic units have passed certification for sale in Australia. So you just keep slotting in more expensive, higher-spec parts until the unit's safe and saleable.

Check out http://a16z.com/2015/08/06/wechat-china-mobile-first/ , it was an interesting perspective shift for me.

mabcat··on Study: Staying off Facebook can make you happier
What is the main rule, exactly? The only way to measure happiness is self-report. Most psych studies in general are self-report. Very hard to get at people's mental states without it.
mabcat··on What’s in a Boarding Pass Barcode?
Virgin Australia prints the PNR and frequent flyer number in plaintext.

I scanned a recent VA boarding pass with a PDF417 scanner, and amongst all the other stuff is 16 characters without an obvious meaning. The boarding pass in the article had a similar region, and another longer one. It would have been interesting for the article to have pulled those apart.
