kapsel | 3 years ago | on: AirPods Pro (2nd Generation)

I love my AirPod Pros, but I hate how unreliable charging in the case is. The AirPods will often think they are out of the case, when they are, and discharge themselves, while connected to my phone/laptop.

Then they will re-charge, emptying the battery in the case, so I will end up with a dead pair of AirPods after a couple of days in the pocket, not using them.

I guess their tolerances are too tight, hopefully something that will be fixed with AirPod Pro 2, it is a big annoyance.

Some times they will also not pick up that they are being put into my ears, so I have to put them back in the case a couple of times for them to react. Really annoying too.

I'm confident that it will go 200km/h - but you will run out of battery quite fast at those speeds (in much less than an hour), as it's obviously a lot less efficient.

I saw multiple machines running RedStar OS, even took photos of me interacting with one of them, on my 2-week trip a couple of years ago.

I commented on another North Korea post here on Hacker News a while ago, where I also posted the URL to the photos, if anyone are curious. It even had IP addresses set and some sort of network (not Internet) access.

Its also worth checking out Poul Henning-Kamps (FreeBSD comitter) work on Ntimed, check out: https://github.com/bsdphk/Ntimed

The overall architectural goals are the same as every other FOSS project claims to follow: Simplicity, Quality, Security etc. etc. but I tend to think that we stick a little bit more closely to them.

This work is sponsored by Linux Foundation, partly in response to the HeartBleed fiasco, and after studying the 300,000+ lines of source-code in NTPD. I concluded that while it could be salvaged, it would be more economical, much faster and far more efficient to start from scratch.

Ntimed is the result.

Do we actually know much about the North Korean "intranet"?

I spent two weeks traveling around in North Korea in August 2012. One of our visits were in a military museum that had computers available (actually running RedStar OS!), containing some CD/DVD with MOV files (as far as I remember) and some other things.

I remember the machine having a 10.x IP address but it was definitely not able to access any internet, but I wonder if it was connected to their actual intranet, or if they simply had some local network there.

kapsel | 11 years ago | on: For Science: Does ZFS deduplication work on intros of TV shows?

I think this was a pretty dumb experiment, and the outcome was to be expected.

There will always be some sort of noise, pixels aligned differently etc., in a production like a tv series, and expecting the encoded output to be identical/matching on a blocklevel is pretty naive to say the least.

I did some experimenting using ZFS deduplication on MPEG2 files, where I encoded hundreds of MPEG2 dvd-sized videos, where 90% of the material was identical (the last 10% was affected by applying different watermarking techniques to the footage), and got some decent deduplication ratio (x1.2:1 or so).. But ZFS deduplication is expensive in memory/SSD, and it was definitely not worth it.

kapsel | 11 years ago | on: The Technology Behind Hyperlapse from Instagram

I mounted my iPhone 5 on my bike this morning, and took a Hyperlapse recording on the bikeride from home to the office (15 minutes).

When I reached the office and stopped the recording, the app would just hang with the text "Processing".. I left it processing for about 4 hours, with no progressbar or anything like it. I ended up giving up, closing the application and rebooting the iPhone. When I launched the program again, it had an error similar to "something bad happened" with a couple of options..

I don't think I'll try be using this program again.

Not sure, but this one is funny:

dig +short -t txt google-public-dns-a.google.com

kapsel | 12 years ago | on: Danish government builds Minecraft world of Denmark from geodata

I have to say that I am quite impressed by their work. I spent 30 minutes earlier, walking around in the neighborhood where I grew up, and it was extremely easy to navigate and recognize roads, houses, and large buildings.

Even the train tracks through the city were there as rails in Minecraft (although not fully connected and working).

Very cool, the guys at GST did some amazing work here.. But as far as I can tell, there is no way to download the full 1TB world?

kapsel | 12 years ago | on: Tarsnap price cut

Tarsnap won't be able to shrink your photos by using deduplication and/or compression. I guess users paying 10$/mo with terabytes of data stored, have massive advantages of both, but it all depends on your usage.

If you are going to store 100GB of photos with Tarsnap, I'd guess it would be close to 25$ as you said. If you just want your photo collection for disaster recovery, you could check out Glacier instead, which is a lot cheaper.

kapsel | 12 years ago | on: On ZFS deduplication and compression support

Use deduplication with caution, and only if your datasets are useful for dedup.

It uses a lot of memory (or SSD, you can add drives as L2ARC to save some money), and it can give you a lot of problems when deleting many files and large datasets.

The somewhat recent addition of LZ4 compression is quite nice.

kapsel | 13 years ago | on: The Jellyfish Entrepreneur

I bought one of these, their latest ones, from a German company about a half year ago. It arrived, I followed the instructions and got it up and running within a couple of hours.

It takes at least a couple of weeks to settle, with the added reef salt and everything. Then I was going to purchase jellyfish - and found out that they actually cost more than 50$ a piece, because of overnight shipping (from Germany, I live in Denmark).

So I started doing some research on the tank, and read about 5 horror stories about how they always died within 3 days, even after following instructions very accurately.

I later emptied the tank, and now it's sitting in the attic.

Build quality is decent, but not perfect. After sitting still for about 3 months, the top lid started bending/skewing quite a lot, now it almost doesn't fit anymore. It's also quite noisy, not something that you'd like to sleep in the same room as.

If anyone wants a jellyfish tank where the jellyfish apparently dies within a couple of days, I have a cheap one for pickup here in Copenhagen.

No, they did not. Their NK part were arranged by KITC, the governmental travel agency of the DPRK.

kapsel | 13 years ago | on: Sophie In North Korea

also, guess why they forgot to take my iPhone when I entrered the country? Because the customs guys were busy playing Angry Birds on my iPad, and looking through my photos.. zooming in on the photos of the pretty girls that I had in my Photostream

kapsel | 13 years ago | on: Sophie In North Korea

Easily. Most in our groups brought some sort of newspapers into the country, they were never confiscated. Our guides would actually ask if it was on to read the newspapers, and our guides knew about what's going on outside of their country. They would know about Assange, Occupy Wall street, Obama etc.

I brought an iPad, my laptop and my iPhone - they only took my iPhone when i entered the country - or, actually, they forgot, and I gave it up later on the trip, as I didn't want to get in troubles when leaving.

I could easily have left many devices there, with information etc.. In terms of communication devices, not so sure. There's absolutely no wifi in the country, and satellite devices are large, afaik.

I was war driving with my iPad in Pyongyang, searching for wifi.. NO wifi was detected, at all. Pretty interesting.

I lend my iPad to one of the guides for a week - the guide saw Breaking Bad Season 1 and heard Beatles and U2 :-) and even brought it home at night.

kapsel | 13 years ago | on: Sophie In North Korea

Not trying to hijack this thread, but I recently spent almost two weeks in the DPRK, and it was one of the most interesting and fascinating trips I ever had.

I took about 5000 photos, and uploaded about 500 of them to my Facebook profile. There's descriptions to many of them. If you're interested, check them out here: https://www.facebook.com/media/set/?set=a.10151040723772055....

And feel free to ask any questions. I'll recommend visiting their country if you get the chance.
