Kirth··on Self-Driving Ubers Driving in Bike Lanes
> Cyclists behind will then simply either have to adjust their speed, or decide whether to cross into the car lane and overtake on the left.

Here's a third option to consider: the cyclist does not notice your merging in to the lane or otherwise fails to react and smashes into the back of your car. At higher speeds this can be lethal.

Kirth··on A Statistical Error in the Estimation of the RDA for Vitamin D
Yesterday's discussion: https://news.ycombinator.com/item?id=15867918
Kirth··on A growing number of young Americans are leaving desk jobs to farm
> Living on one salary, even just with my wife at the time, was impossible in Belgium.

Although tech in Belgium isn't as well paid/rockstar-ish as the rest of Western Europe, that's a bit much.

Where were you living, what were you earning?

Kirth··on The Pleasures of Pessimism
> I cannot stand people who complain when they live in a first world country. I find it so insulting for the entirety of the third world out there.

Although such a response is understandable, it's also very counterproductive. Give it 300 years and all nations will be facing these "first world"-problems.

We should not be sweeping these problems under the rug, but try our best to solve them for everyone.

Kirth··on IBM, a Pioneer of Remote Work, Calls Workers Back to the Office
> It's about incentives.

I see being allowed to work from home as a sign of respect and confidence. Therefor I return that respect by not fucking with said opportunity.

Given the ability to schedule in chores or a bit of fun during breaks, my breaks become far more productive.

When I get stuck or something or am blocking on someone at work, I tend to browse hackernews, some forums, ... You end up with activities that draw you in more and more, potentially wasting hours without really having the refreshing effect you need breaks to have.

When I'm at home, I get up and vacuum a couple of rooms, clean the kitchen or maybe even skip out an hour to work out when the gym's calm to help clear my mind. I'm confident in saying my days spent working from home are by far the most productive of my entire week.

> If they're at home they can play computer games, go out, watch a movie, etc... Someone like that can just as well be expected to spend their entire days scrolling through cat pictures. Don't hire someone you think you can't trust working from home, they won't fare much better on-site.

Kirth··on Study finds association between eating hot peppers and decreased mortality
Around here (Western Europe) I've never heard or seen anyone say they believed spicy food was healthy. I mostly got told too much of it is bad for your liver, though I don't know how well proven that is either.
Kirth··on Please don’t pay to use a pay toilet
I'm reminded of this the "urine reflecting wall paint" they want to apply in Hamburg. I highly doubt it'll solve anything: at the end of the day the streets will still reek of piss. (https://www.theguardian.com/world/2015/nov/27/walls-that-pee...)

Does anyone know what public toilets cost (in construction and maintenance)?

Kirth··on Why is machine learning ‘hard’?
I've met some people whom believe that the more modern tools (such as Tensorflow) magically require little human input and make it so that you do not need to know/understand the mathematics and statistics. Not sure where they get this idea.

Everyone wants to do machine learning, but nobody seems to want to learn statistics.

Kirth··on Apache Spark: A Unified Engine for Big Data Processing
No, but you also won't be using all that data at the same time. On Hadoop (and Spark on HDFS) clusters you'll find that most disks are either not that big or are heavily under-used.

Our HBase cluster had 6 * 2Tb disks: about 8.5Tb of usable storage (the other 3.5Tb accounts for data replication/duplication) per host in the cluster. However, you need about 200 bytes in memory per kb on disk and should assign only 32Gb of heap to HBase. That's 2.5Tb wasted, per host. Couldn't just plug those disks out and use them somewhere else: you need all the disks in parallel to overcome the IO/bandwith bottleneck.

Kirth··on Pokemon Go, Security, and Obsolescence
In one of their past banwaves, getting off a high speed train or airplane and then killing some time at the airport playing Pokemon Go often got you banned because of "teleporting". (Not always a temporary shadowban)

Getting support to even respond to your mails (even when they're related to other issues) seems to be a matter of waiting for the right stars to align.

Kirth··on Learning systems programming with Rust
> You should learn C. This is not up for debate, and you should learn it even if you don't plan to write it.

Although I agree [that a systems programmer should know C], your comment lacks any value if you don't explain as to why.

Kirth··on Learning systems programming with Rust
Which is a shame, because a few of them do a pretty good job at visualizing the problem/information at hand. Unfortunately, they get drowned out by the sheer amount of images that serve no real purpose.
Kirth··on If English were written like Chinese (1999)
I'm not sure where you've seen this "increasing use of icons and emoji". When I encounter people (this is pretty much limited to teenagers) use emoji, they have very little communicative value.

In the modern era the use of pictographs has become Chinese's Achilles' heel: the hanzi are not sortable. The very things that define the Chinese are what makes it stupidly difficult to get computers to grok the language.

Kirth··on Dutch men confirmed as world's tallest
I'd like to see you back that one up with proof :). My doctor told me a vitamin D deficiency is not problematic in Caucasian Europeans.
Kirth··on NASA Software Safety Guidebook (2004) [pdf]
> Oh, you noticed that this 500 line copy paste function could be replaced by three 80 line functions? Sorry buddy, before you can change this you have to fill out this form in triplicate and what for a decision from three middle managers. Maybe we can fit this change in the next release, but don't get your hopes up.

Because as it turns out, writing mission critical, one-off software is difficult. Touching a piece of code that's firmly embedded in the system could have serious consequences. (Of course, it shouldn't; any mistakes should be caught by testing but we all know how that goes.)

These are rules for a place that makes massive, expensive and dangerous things, not a webdev shop.

Kirth··on Living in Switzerland ruined me for America and its lousy work culture
Because this concept stems from a time when people still performed physical work and had to eat at least 3 full meals spread over the day to stay healthy (enough).

Reading the comments here makes me realise how firmly embedded the "time not spent working is time wasted" attitude is.

Kirth··on Thoughts on Time-series Databases
We've had issues with Influx being a massive resource hog. Not properly persisting data to disk. They openly admit that Influx isn't built to gracefully recover from crashes, and that you will lose data.

This by itself wouldn't be a problem for us. But when you're inserting data points, the entire damn thing seems to become unresponsive. Admin UI freezing, http endpoint no longer responding to queries, ...

I know this product is relatively young and your mileage may vary. They have a long way to go.

Kirth··on Thoughts on Time-series Databases
"Seems to be", sure. Sinks like a tanker when you try to actually use it, though. None of the software libraries have been updated for 0.9 yet.
Kirth··on Does UPS routinely lie about delivery status?
Curious whether parcel delivery companies have their drivers manually validate when the package has been delivered. Or is the status an estimate based on time/progress?
Kirth··on In Busy Silicon Valley, Protein Powder Is in Demand
And that's what makes it a meal (replacement). You can't survive on whey protein shakes alone. If the malnutrition doesn't kill you, the smell of your farts surely will.
Kirth··on In Busy Silicon Valley, Protein Powder Is in Demand
And a supplement at best -- not a meal.
