A completely routine tech support ticket has uncovered unexpected bans of IP addresses of Protonmail — a very useful service for people valuing their Internet freedoms — in several regions of Russia. I seriously didn’t want to sensationalize the headline, but the story is so strange and inexplicable I couldn’t resist.
Disclaimer: the situation is still developing. There might not be anything malicious, but most likely there is. I will update the post once new information comes through.
MTS and Rostelecom — two of the biggest Russian ISPs — started to block traffic to SMTP servers of the encrypted email service Protonmail according to an FSB request, with no regard for the official government registry of restricted websites. It seems like it’s been happening for a while, but no one paid special attention to it. Until now.
All involved parties have received relevant requests for information which they’re obligated to reply.
UPD: MTS has provided a scan of the FSB letter, which is the basis for restricting the access. Justification: the ongoing Universiade in Krasnoyarsk and “phone terrorism”. It’s supposed to prevent ProtonMail emails from going to emergency addresses of security services and schools.
UPD: Protonmail was surprised by “these strange Russians” and their methods for battling fraud abuse, as well as suggested a more effective way to do it — via abuse mailbox.
UPD: FSB’s justification doesn’t appear to be true: the bans broke ProtonMail’s incoming mail, rather than outgoing.
UPD: Protonmail shrugged and changed the IP addresses of their MXs taking them out of the blocking after that particular FSB letter. What will happen next is open ended question.
UPD: Apparently, such letter was not the only one and there is still a set of IP addresses of VOIP-services which are blocked without appropriate records in the official registry of restricted websites.
StarCraft: Brood War. This game means so much to me! And to many of you, I guess. So much, that I wonder if I should even give a link to its page on Wikipedia or not.
Once Halt sent me PM and offered to learn Rust. Like any ordinary people, we decided to start with
hello world writing a dynamic library for Windows that could be loaded into StarCraft's address space and manage units.
The following article will describe the process of finding solutions and using technologies and techniques that will allow you to learn new things about Rust and its ecosystem. You may also be inspired to implement a bot using your favorite language, whether it be C, C++, Ruby, Python, etc.
Good day to you!
My name is Stanislav and I like to write code. This is my first english article on Habr which I made due to several reasons:
This article is an english version of my very first article on russian.
Let me introduce the main figures in this story who actually fixed the bug preventing Git from running in ReactOS — the French developer Hermès Bélusca-Maïto (or just Hermes with
hbelusca nickname) and of course me (with
The story begins with the following messages from the ReactOS Development IRC channel:
Jun 03 18:52:56 <hbelusca> Anybody want to work on some small problem? If so, can someone figure out why this problem https://jira.reactos.org/browse/CORE-12931 happens on ReactOS? :D Jun 03 18:53:13 <hbelusca> That would help having a good ROS self-hosting system with git support.

It seems we came through hell and high water and can nail any interview, even the one for .NET CLR team. However, let's not rush to microsoft.com and search for vacancies. Now, we need to understand how value types inherit an object if they contain neither a reference to SyncBlockIndex, not a pointer to a virtual methods table. This will completely explain our system of types and all pieces of a puzzle will find their places. However, we will need more than one sentence.
Now, let's remember again how value types are allocated in memory. They get the place in memory right where they are. Reference types get allocation on the heap of small and large objects. They always give a reference to the place on the heap where the object is. Each value type has such methods as ToString, Equals and GetHashCode. They are virtual and overridable, but don’t allow to inherit a value type by overriding methods. If value types used overridable methods, they would need a virtual methods table to route calls. This would lead to the problems of passing structures to unmanaged world: extra fields would go there. As a result, there are descriptions of value type methods somewhere, but you cannot access them directly via a virtual methods table.
This may bring the idea that the lack of inheritance is artificial

Apple Swift version 5.0 (swiftlang-1001.0.45.7 clang-1001.0.37.7) Target: x86_64-apple-darwin18.2.0 ABI version: 0.6
Swift apps no longer include dynamically linked libraries for the Swift standard library and Swift SDK overlays in build variants for devices running iOS 12.2, watchOS 5.2, and tvOS 12.2. As a result, Swift apps can be smaller when deployed for testing using TestFlight, or when thinning an app archive for local development distribution.Application Binary Interface stability is coming! And this is excellent news. I think this is the one of the most significant issues at the moment with Swift. Not because of side-effects but because of Swift’s failure to deliver on previous promises. Anyway, I even know people who rewrite their Apple Watch extensions to Objective C to reduce the size of binary (something like 15MB vs ~1MB in Objective C). If you want to know more about the state of ABI, follow the links: Swift — ABI Dashboard and Swift ABI Stability Manifesto.
