efesak··on Japan is gripped by mass allergies. A 1950s project is to blame
The spruce and other local conifers (I live by the Bohemian Forest/Bayerischer Wald) have pollen that seems to be low allergenic by design. I know a lot of people who are allergic to birch or weed pollen, but not to spruce.
efesak··on An Interesting Find: STM32 RDP1 Decryptor
This thing just makes it easier to dump the firmware, but it's not a revolution or anything. The STM issues have been known about for a while, and with a bit of effort, you can dump it yourself without this or any expensive tools, as I once did: https://analogic.cz/rs41-rpm411/
efesak··on How to Get a North Korea / Antarctica VPS
Cloudflare does not have any IPv4 blocks in North Korea. Geolocation databases use RIPE as the primary source and then make estimates using various tools.

Interestingly, according to RIPE, North Korea has only assigned one IPv4 block (see https://github.com/analogic/ipgeo/blob/master/by-country/KP), whereas Antarctica has none.

efesak··on SMTP Smuggling – Spoofing Emails Worldwide
It seems Haraka is safe (eg. poste.io stack)

efesak··on Ask HN: Which boring technology do you still use?
Email.
efesak··on Self-hosted email is the hardest it's ever been, but also the easiest
For only your personal use sure. If you run stack for more than couple users you will sooner or later hit problems not with software itself but with outer world.
efesak··on Self-hosted email is the hardest it's ever been, but also the easiest
Running self-hosting email is not problem. There is so much solutions to run easily own server these days. But the main problem is that you need a lot of knowledge to do that properly - software might help but it will never be "run and forget" service type.

For example large part of IT professionals which contacts our support (https://poste.io) don't get difference between SMTP envelope and from/to headers.

efesak··on I made a simple geolocation service
Also please see https://github.com/analogic/ipgeo daily actualized ip/country database with open license (shameless ad)
efesak··on We're making an open-source $30 GPS/mesh radio, would like advice
FLARM is very bad example especialy for DIY community. They have proprietary chips, firmware and are running non opensourced protocol. Also they are actively trying to prevent reverse engineering with cryptography and killing old/diy devices with protocol timebombs...
efesak··on Ask HN: What are some interesting projects to reuse your old devices?
Using broken phone (nexus 5x) with nice camera for timelapsing hill for paragliding club

efesak··on How to run your own mail server (2017)
These tutorials are nice but you can just hack https://hub.docker.com/r/analogic/poste.io (shameless ad) or any other containerized solution. You will get fully working solution in couple minutes and it will be somewhat easy to keep mailserver updated...
efesak··on Support for U2F security keys
Try https://www.enpass.io (I sync db through Dropbox but you can use almost whatever you want...)
efesak··on Navy pilots report unexplained flying objects
Uh, It just seems like insect in the sensor
efesak··on Show HN: WildDuck – Self-hosted modern email server
See poste.io, it solves exactly this problem. (I've created poste because I administer multiple smaller mailserevers and thus scratching my own itch)
efesak··on Is This the Beginning of the End of the Bitcoin Bubble?
https://en.wikipedia.org/wiki/Betteridge%27s_law_of_headline...
efesak··on Decentralization in Bitcoin and Ethereum
I have been running multiple bitcoin and altcoin nodes and still I am not able to run public geth node synced for month on dedicated server (4c SAS disks). So if "Bitcoin Underutilizes Its Network" then Ethereum is actively destroying itself.
efesak··on OcherBook: Open-source replacement Kobo firmware
Yes especialy kobo mini is fun device. Large community of paragliding pilots are using it as flight computer by adding GPS and pressure sensor. See http://unity.paragliding.xyz/wp-content/uploads/2015/05/Unit...
efesak··on Bitcoin's ASICBOOST Problem Explained [pdf]
- there are ~5000 LOC of https://github.com/bitcoin/bitcoin/pull/7910/files and almost 3/4 of these lines are tests.

- Segwit actualy block harmful form of ASICBOOST

- by "growing majority" you mean handful of chinese miners and 2% of nodes (http://luke.dashjr.org/programs/bitcoin/files/charts/softwar...)

efesak··on Ask HN: Is it possible to run your own mail server for personal use?
Sure! I run several servers (and developing them, see https://poste.io). Watch DMARC reports and give it little time, most of time it will solve itself. You can also register to feedback loop...
efesak··on Ask HN: How do we replace our POP3 email solution?
https://poste.io
efesak··on Using Free SSL/TLS Certificates from Let’s Encrypt for Nginx
I think its not gona be easy as that - there has to be some croned process and some kind of error handling. (I created https://hub.docker.com/r/analogic/lemanager/ which does both but i am still waiting for some better "native" solution)
efesak··on Deploy a .onion Site in Less Than 5 minutes
I use https://hub.docker.com/r/goldy/tor-hidden-service/ (just 2 commands) ... it just simply works
efesak··on Your own Debian Mail Server (part II): how to prove you are not a spammer

efesak··on Show HN: Poste.io – full featured mail server installed in Docker container
Thanks! SPF is matter of DNS only. DKIM can be added to domain through command line even in free version. (but you are right, i will release DKIM to free version also)

Hi, i made poste.io. If you have questions or you have some suggestion please comment or email me at admin@poste.io
efesak··on Against DNSSEC
> DNSSEC is Expensive To Adopt/Deploy

I live in .cz domain and almost every registrar there have DNSSEC in one click (without changing price) - adoption here is 40%! - see https://stats.nic.cz/stats/domains_by_dnssec/ and I am not experiencing any mentioned problems at all

Maybe DNSSEC is not best DNS proto in the world, but these arguments are not entirely based on facts.

efesak··on Your language sucks
I am from country with strongly phonetical language and you are just plainly wrong. There are minor dialects but it is considered rather as slang in compare to language taught in schools or comunicate with officials or even broader audience.

(On the other side, it is much more difficult for us to learn English and get used to that disconection between alphabet and said words. And we don't have spelling competitions :).)
