Organic Maps 17 days ago

In some places it always was better (it's OpenStreetMap data) e.g. in the Puna de Atacama desert in Argentina/Chile, Google Maps is years behind in therms of map precision. Lots of roads are missing from Google Maps. Plus, OrganicMaps working totally offline, it's perfect for such a place where the only Internet would be by satellite.

how did you come to this conclusion

I didn't see any reference to the possibility of using anything else on their website. And yes I was only speaking of authbound.

I think that the start of the article is at least a bit exaggerated:

    SSH is yet another example of an ancient technology that is still in wide use today.
Ancient technology? If it was telnet or FTP... But SSH is much younger than, let's say, IPv4, which is _maybe_ ancient technology still in wide use today.

The problem is that µ is usually hard to type (unless you have a Greek keyboard or a custom keyboard mapping). This said, although I tolerate stuff like "47 uF" in electronic schematics (also because legacy software didn't even allow the µ symbol), I definitely find horrible to see stuff like "us" instead of "µs" in an article.

Everybody I know uses IM systems like Wechat, WhatsApp, Telegram, Signal.

Great, instead of having a single, standard and interoperable way to communicate (albeit with its defaults), now we need to have 5, 6, 7 different closed systems that can't speak with each other, most of which require a working smartphone in order to even have an "address". What a wonderful evolution...

What does this bring compared to apt-get install-ing an established mail server like procmail or exim and configuring it to work as a relay for the local LAN?

I've yet to read a good explanation of why the telcos permit CLID faking and reinjection of apparently local CLID by overseas inputs.

Actually, there are several legitimate use cases:

• Call divert: Local number calls a number abroad and that one is diverted back a another local number. It's probably rare, but it's a totally legit use case.

• 2G/3G roaming: I'm not an expert on this one, but as far as I understood it, roaming calls placed on 2G/3G networks are initiated in the visiting country, and use the local number of the caller.

• Getting better rates using VoIP. Whether this is legit or not might be subject to discussion, however I was using a foreign VoIP provider (because they had better rates for local calls than any local providers, for my low call volume) sending out my own local number (had to be validated by them by callback, although that's their own security measure, not the network's one). Now in several EU countries and Switzerland this doesn't work any more, as calls bearing national IDs coming from abroad must be displayed as anonymous. And it's quite annoying that there isn't a way to "authentify" those numbers so the owner can use them as they wish.

An e-mail address can have multiple @ also for... source routing. Of course it doesn't make any sense nowadays, but it's technically allowed. RFC 5321 gives an example:

  @hosta.int,@jkl.org:userc@d.bar.org
This is a valid e-mail address, with source-routing along two intermediate servers. I guess no sane server on the Internet will accept this, but you never know... (this said, I remember attempting this around 1996, when many servers were open relays, and the message was happily delivered after passing through 3-4 servers).

Weren't similar techniques already used years ago by malvertizers to hide malicious code into images published for ads so it wouldn't be detected? (although it might have been more like steganography)

It seems the site basically doesn't do anything for IPv6 :-(

I see the same problem with rDNS. The box at the top correctly reports the DNS name as "forward-confirmed" but I see a -5 points penalty for missing reverse DNS. Tried with various IP addresses, and I observe the same for many (not all).

Can the same version of Word now produce the same rendering on two PCs? In the past (I didn't really check recently, I'm thinking more about 10 years ago) the same file might have had page breaks in different positions and things like that. I never understood if it came from slightly different versions of the fonts, from some info derived from the default printing or anything else...
