100% this. They took away all the (often very personal) reviews that is part of my account, and forced me to pay for access to them.

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.

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.

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

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?

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.

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.
