wartijn_··on Falsehoods programmers believe about time zones
> "Turns out this day won't exist for you" is never something I'd have considered a possibility.

When countries switched from the Julian to the Gregorian calendar this happened everywhere. Entire counties skipping weeks in their calendars. Historical documents referring to the same event but using different dates, because they were using different calendars. Fun times. And of course not every country switched at the same time.

The Wikipedia page about this is pretty interesting [0] Some quotes from that page:

> In Russia, the Gregorian calendar was accepted after the October Revolution. On 24 January 1918 the Council of People's Commissars issued a decree that Wednesday, 31 January 1918, was to be followed by Thursday, 14 February 1918, thus dropping 13 days from the calendar.

> Catholic countries such as the Polish–Lithuanian Commonwealth adopted the "new style" (N.S.) Gregorian calendar in 1582 (switched back in 1795 after Third Partition of Poland)

And if you think that is bad, the Roman calendar that was replaced by the Julian calendar had a year consisting of 304 days and when things got too much misaligned with the seasons some extra days would be added [1]

> The system is usually said to have left the remaining 50 odd days of the year as an unorganized "winter", although Licinius Macer's lost history apparently stated the earliest Roman calendar employed intercalation instead[7][8] and Macrobius claims the 10 month calendar was allowed to shift until the summer and winter months were completely misplaced, at which time additional days belonging to no month were simply inserted into the calendar until it seemed things were restored to their proper place.

Good thing computers weren't around back then.

wartijn_··on How Normal Am I?
Nice project :) Too bad it doesn't say how old it thinks you are though (or I missed it) All I know now is that it thinks I lied about my age, which I didn't.

I'm just going to assume I look like I'm 20

wartijn_··on Xkcd: Messaging Systems
> A smartphone, you mean

I actually mean a mobile phone, because I don't know anyone who only has a "dumb" phone. A know a few people didn't have a smartphone for a while, but they've all got one now.

Maybe some of my great aunts don't have a smartphone, but everyone else I know between the ages of 11 and 70 does have a smartphone with WhatsApp installed on it.

wartijn_··on Xkcd: Messaging Systems
I know WhatsApp isn't supported by everyone, but in some parts of the world it almost is. I don't know anyone with a mobile phone, but without WhatsApp.

Can you point out from where in that report you've got those numbers? I couldn't find them.
wartijn_··on Trevor Milton Out of Nikola Motors
I'm actually surprised how much the stock is still worth. It looks[0] like they're still worth more than when they went public in June.

Btw: when the Hindenburg report was published, it was also discussed on hn[1]

wartijn_··on A Keyboard with Blank Keycaps Made Me an Expert Typist
It's off course hard to find the average typing speed of everybody who types, but Wikipedia says this:

> An average professional typist types usually in speeds of 50 to 80 wpm, while some positions can require 80 to 95 (usually the minimum required for dispatch positions and other time-sensitive typing jobs), and some advanced typists work at speeds above 120 wpm.[4] Two-finger typists, sometimes also referred to as "hunt and peck" typists, commonly reach sustained speeds of about 37 wpm for memorized text and 27 wpm when copying text, but in bursts may be able to reach much higher speeds.

wartijn_··on Touch Typing on a Gamepad
Cool idea, but wouldn't it make sense to remove the letter J from the most used letters?

If you don't use that letter for Vim it drops from the top 8 all the way to the bottom of the frequency chart (assuming you only type English). If you than map whatever J does in Vim to a more frequently used letter your typing speed should go up.

Alternatively since J seems to be used mostly for navigation (not sure, I don't use Vim) use the d-pad to do that instead.

> After I upgraded my gamepad to the DualShock4, I realized I could make diagonal inputs relatively accurately. Integrating diagonal inputs would reduce the number of more complex inputs required thus increasing speed.

Any plans to do that?

wartijn_··on Samsung Blu-ray players bricked because of an XML config file
I don't think these kind ofdevices will use Starlink or an equivalent service any time soon. Starlink needs a "pizza box sized" satellite dish that constantly adjusts its position to stay in contact with the satellites. I assume they won't work inside, like other satellite based antennae.

If smart devices will have build in connectivity in the next decade, I think 5g will be a more likely candidate. But I don't see that happening either. Why would a company pay for the data of its users when most people will just connect it to their wifi?

I. Couldn't find a source on "pizza box sized", but I remember Elon Musk has said that. Also here is a picture of one of the antennae: https://www.reddit.com/r/Starlink/comments/hruzck/new_photo_...

wartijn_··on Is It Time to Kill the Penny?
Here is the government website that says so and its translation (with a really long url, but the translation is better than that of Google Translate).

Appearantly every shop should have stickers telling customers that they round cash payments. I've never noticed that anywhere.

wartijn_··on Is It Time to Kill the Penny?
You should be able to pay with 1 and 2 cent coins in The Netherlands. You just won't get them as change and the amount charged will be rounded to the nearest 5 cents in most, but not all, shops. But I wouldn't be surprised if many cashiers don't know they should accept those coins.
wartijn_··on No More Coffee
A cup of coffee has way more caffeine than tea.

Coffee has 163mg per cup, black tea 42mg and green tea 25mg.[0][1][2]

1kg of dry tea does have more caffeine than 1kg of coffee beans, according to Wikipedia[3]

> Tea contains more caffeine than coffee by dry weight. A typical serving, however, contains much less, since less of the product is used as compared to an equivalent serving of coffee. Also contributing to caffeine content are growing conditions, processing techniques, and other variables. Thus, teas contain varying amounts of caffeine

Also kinda interesting: I've often seen people opt for an espresso instead op a cup of coffee, because they say they need the caffeine. But an espresso has only 77mg of caffeine, way less caffeine than a cup of coffee. [4] (Unless you fill a coffee cup with espresso shots, but who does that?)

wartijn_··on Do I need to go to university?
Are technical fields really an edge case?

I suspect going to a university is helpful in most STEM related fields. In anything medical or law related you don't even have to think about getting a job without a degree. I don't see how anyone can compensate an economical or business study by doing project on their own.

If anything I think IT is an outlier, because not going to university and learning the subjects you would have been taught on your own might be a valid option.

wartijn_··on Google can use Bluetooth to track phones even with Bluetooth turned off (2018)
I second this. On my Android One phone (so pretty much stock Android) with Android 10, all it says is: "When Bluethooth is turned on, your device can communicate with other nearby Bluetooth devices."
wartijn_··on Dutch adopt controversial ‘herd immunity’ strategy
The Dutch government isn't in denial though. Cafes, restaurants, schools universities and day cares are closed. Large gatherings are forbidden and people are encouraged to work from home and be sensible about having contact with other people.

According to the PM, the chosen strategy should prevent both a super high hospitalization rate and a lengthy lock-down of the entire country.

wartijn_··on Rendering on the Web
I didn't downvote you, but I guess it's because:

a) From the way your comment is written, it's pretty clear that you actually just want to say what's between the brackets in your second comment. It comes accros as passive aggressive and doesn't contribute anything.

b) The page mentions who have written this article. The names, positions at Google and pictures are all there.

wartijn_··on Why we're saying no to Google
I thought this was only about the search app/widget, not also about the browser and the browsers default search engine. My bad.

But I don't think it's just shifting down the problem.

Right now the search app, browser and search engine of the browser are all Google. I don't think an unremovable* search widget on phones is necessary. And I think Google wants to keep it there because they know people will choose Google, especially since that one is installed by default and users just get the choice between installing an extra app or skip that step.

*unless you install a new launcher.

wartijn_··on Why we're saying no to Google
Maybe option 6: Don't have a search app by default?

I don't see why such an app is required. If user need to search for something, they can use their browser. And if someone wants to have a browser app/widget they can download it from the Play store.

This "solution" by Google is just a way to prevent more fines, while most people will still have a huge Google search bar on their phone and Google can make some extra money.

wartijn_··on When Can I Reuse This Calendar?
I don't have the source code of this site, but checking if a calendar can be used again is pretty easy.

1. Check which weekday the year starts

2. Check if this year is a leap year.

If the year starts on the same weekday as another year and the leap-yeariness is the same, the year is the same.

With this info it's really easy to use your favorite date library to check which years match, but you can also do that manually.

Each year starts on the next weekday that the previous year did. (2019-01-01 was a Tuesday, 2020-01-01 will be a Wednesday) except when that previous year was a leap year. In that case one day is skipped.

wartijn_··on More than 1k Android apps harvest data even after you deny permissions
According to Google Bluetooth requires location, because it van be used to find your location. So there is some reasoning behind this decisions, although I wwould be mutch happier with something like: Location (Bluetooth), location (GPS), location (WiFi)

>A location permission is required because Bluetooth scans can be used to gather information about the location of the user. This information may come from the user's own devices, as well as Bluetooth beacons in use at locations such as shops and transit facilities.

https://developer.android.com/guide/topics/connectivity/blue...

wartijn_··on More than 1k Android apps harvest data even after you deny permissions
From the article:

> The 1,325 apps that violated permissions on Android used workarounds hidden in its code that would take personal data from sources like Wi-Fi connections and metadata stored in photos.

> Researchers found that Shutterfly, a photo-editing app, had been gathering GPS coordinates from photos and sending that data to its own servers, even when users declined to give the app permission to access location data.

> Some apps were relying on other apps that were granted permission to look at personal data, piggybacking off their access to gather phone identifiers like your IMEI number. These apps would read through unprotected files on a device's SD card and harvest data they didn't have permission to access. So if you let other apps access personal data, and they stored it in a folder on the SD card, these spying apps would be able to take that information.

So basically, they can't read your location, but they can read other things that contain your (previous) location and other information about you.

Edit: The article links to the original research[0], which seems to describe/link to different methods that the apps use. I haven't had time to read it yet, but it seems interesting.
