+    TVL's public inbox
+    ==================
+
+    This is the [public-inbox][] for [The Virus Lounge][TVL]. It is
+    essentially like a pull-based mailing list, where we discuss
+    anything related to our software or organisation, as well as
+    receive patches from external users.
+
+    ## Posting to the inbox
+
+    Anyone can send messages to the inbox by emailing
+    **depot@tvl.su**.
+
+    ## Accessing the inbox
+
+    There are several ways to access the inbox, depending on what is
+    most convenient for your personal email workflow.
+
+    ### Web browser
+
+    Go to [`/depot/`][inbox-html] to read the inbox in your web
+    browser. This is the easiest way to access messages, and with an
+    email client supporting `mailto:` links you can respond to
+    messages from there, too.
+
+    ### IMAP
+
+    The inbox is available via IMAP:
+
+    **Server:** `inbox.tvl.su`
+
+    **Port:** `993` (TLS enabled)
+
+    **Inbox:** `su.tvl.depot.0` (auto-discoverable)
+
+    You can use *any* credentials to log in, for example the username
+    `anonymous` with the password `kittens`. The server will just
+    ignore it.
+
+    TIP: There is a wrapper script in `//tools/fetch-depot-inbox` in
+    the TVL depot which you can use to synchronise the maildir to your
+    computer, which works for email clients like `notmuch`.
+
+    ### Atom feed
+
+    An Atom feed [is available][feed] and should work with your
+    favourite feed reader.
+
+    ### NNTP
+
+    News readers can access the inbox via NNTP:
+
+    **Server:** `inbox.tvl.su`
+
+    **Port:** `563` (TLS enabled)
+
+    **Group:** `su.tvl.depot.0` (auto-discoverable)
+
+    No credentials are required to access the server.

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

+We've now been working on our rewrite of Nix, [Tvix][], for a little more than
+two years.
+
+Our last written update was in September 2023, and although we did publish a
+couple of things in the meantime (flokli's talk on Tvix at [NixCon
+2023][nixcon2023], our interview at the [Nix Developer
+Dialogues][nix-dev-dialogues-tvix], or tazjin's [talk on
+tvix-eval][tvix-eval-ru] (in Russian)), we never found the time to write
+something down.
+
+In the meantime a lot of stuff has happened though, so it's time to change that
+:-)
+
+Note: This blog post is intended for a technical audience that is already
+intimately familiar with Nix, and knows what things like derivations or store
+paths are. If you're new to Nix, this will not make a lot of sense to you!
+
+## Evaluation regression testing
+
+Most of the evaluator work has been driven by evaluating `nixpkgs`, and ensuring
+that we produce the same derivations, and that their build results end up in the
+same store paths.
+
+Builds are not hooked up all the way to the evaluator yet, but for Nix code
+without IFD (such as `nixpkgs`!) we can verify this property without building.
+An evaluated Nix derivation's `outPath` (and `drvPath`) can be compared with
+what C++ Nix produces for the same code, to determine whether we evaluated the
+package (and all of its dependencies!) correctly [^1].
+
+We added integration tests in CI that ensure that the paths we calculate match
+C++ Nix, and are successfully evaluating fairly complicated expressions in them.
+For example, we test against the Firefox derivation, which exercises some of the
+more hairy bits in `nixpkgs` (like WASM cross-compilation infrastructure). Yay!
+
+Although we're avoiding fine-grained optimization until we're sure Tvix
+evaluates all of `nixpkgs` correctly, we still want to have an idea about
+evaluation performance and how our work affects it over time.
+
+For this we extended our benchmark suite and integrated it with
+[Windtunnel][windtunnel], which now regularly runs benchmarks and provides a
+view into how the timings change from commit to commit.
+
+In the future, we plan to run this as a part of code review, before changes are
+applied to our canonical branch, to provide this as an additional signal to
+authors and reviewers without having to run the benchmarks manually.
+
+## ATerms, output path calculation, and `builtins.derivation`
+
+We've implemented all of these features, which comprise the components needed to
+construct derivations in the Nix language, and to allow us to perform the path
+comparisons we mentioned before.
+
+As an interesting side note, in C++ Nix `builtins.derivation` is not actually a
+builtin! It is a piece of [bundled Nix code][nixcpp-builtins-derivation], that
+massages some parameters and then calls the *actual* builtin:
+`derivationStrict`. We've decided to keep this setup, and implemented support in
+Tvix to have builtins defined in `.nix` source code.
+
+These builtins return attribute sets with the previously mentioned `outPath` and
+`drvPath` fields. Implementing them correctly meant that we needed to implement
+output path calculation *exactly* the same way as Nix does (bit-by-bit).
+
+Very little of how this output path calculation works is documented anywhere in
+C++ Nix. It uses a subset of [ATerm][aterm] internally, produces "fingerprints"
+containing hashes of these ATerms, which are then hashed again. The intermediate
+hashes are not printed out anywhere (except if you [patch
+Nix][nixcpp-patch-hashes] to do so).
+
+We already did parts of this correctly while starting this work on
+[go-nix][go-nix-outpath] some while ago, but found some more edge cases and
+ultimately came up with a nicer interface for Tvix.
+
+All the Derivation internal data model, ATerm serialization and output path
+calculation have been sliced out into a more general-purpose
+[nix-compat][nix-compat-derivation] crate, alongside with more documentation
+unit tests and a Derivation ATerm parser, so hopefully this will now be more
+accessible for everyone now.
+
+Note our builtin does *not* yet persist the Derivation anywhere "on
+disk" (though we have a debug CL that does write it to a temporary directory,
+in case we want to track down differences).
+
+## `tvix-[ca]store`
+Tvix now has a store implementation!
+
+### The Nix model
+Inside Nix, store path contents are normally hashed and communicated in NAR
+format, which is very coarse and often wasteful - a single bit of change in one
+file in a large store path causes a new NAR file to be uploaded to the binary
+cache, which then needs to be downloaded.
+
+Additionally, identifying everything by the SHA256 digest of its NAR
+representation makes Nix store paths very incompatible with other
+content-addressed systems, as it's a very Nix-specific format.
+
+### The more granular Tvix model
+After experimenting with some concepts and ideas in Golang, mostly around how to
+improve binary cache performance[^3], both on-disk as well as over the network,
+we settled on a more granular, content-addressed and general-purpose format.
+
+Internally, it behaves very similar to how git handles tree objects, except
+blobs are identified by their raw BLAKE3 digests rather than some custom
+encoding, and similarly, tree/directory objects use the BLAKE3 digest of its
+canonical protobuf serialization as identifiers.
+
+This provides some immediate benefits:
+ - We only need to keep the same data once, even if it's used across different
+   store paths.
+ - Transfers can be more granular and only need to fetch the data that's
+   needed. Due to everything being content-addressed, it can be fetched from
+   anything supporting BLAKE3 digests, immediately making it compatible with
+   other P2P systems (IPFS blake3 blobs, …), or general-purpose
+   content-addressed caches ([bazel-remote]).
+
+There's a lot more details about the data model, certain decisions etc. in
+[the docs][castore-docs].
+
+### Compatibility
+We however still want to stay compatible with Nix, as in calculating
+"NAR-addressed" store paths the same, support substituting from regular Nix
+binary caches, as well as storing all the other additional metadata about store
+paths.
+
+We accomplished this by splitting the two different concerns into two separate
+`tvix-store` and `tvix-castore` crates, with the former one holding all
+Nix-specific metadata and functionality, and the latter being a general-purpose
+content-addressed blob and filesystem tree storage system, which is usable in a
+lot of contexts outside of Tvix too. For example, if you want to use
+tvix-castore to write your own git alternative, or provide granular and
+authenticated access into large scientific datasets, you could!
+
+### Backends
+In addition to a gRPC API and client bindings, there's support for local
+filesystem-based backends, as well as for sled, an embedded K/V database.
+
+We're also currently working on a backend supporting most common object
+storages, as well as on more granular seeking and content-defined chunking for
+blobs.
+
+### FUSE/virtiofs
+A tvix-store can be mounted via FUSE, or exposed through virtiofs[^4].
+While doing the obvious thing - allowing mounting and browsing the contents
+of the store, this will allow lazy substitution of builds on remote builders, be
+in containerized or virtualized workloads.
+
+We have an [example][tvix-boot-readme] in the repository seeding gnu hello into
+a throwaway store, then booting a MicroVM and executing it.
+
+### nar-bridge, bridging binary caches
+`nar-bridge` and the `NixHTTPPathInfoService` bridge `tvix-[ca]store` with
+existing Nix binary caches and Nix.
+
+The former exposes a `tvix-[ca]store` over the common Nix HTTP Binary Cache
+interface (both read and write).
+
+The latter allows Tvix to substitute from regular Nix HTTP Binary caches,
+unpacking NARs and ingesting them on-the-fly into the castore model.
+The necessary parsers for NARInfo, signatures etc are also available in the
+[nix-compat crate][nix-compat-narinfo].
+
+## EvalIO / builtins interacting with the store more closely
+tvix-eval itself is designed to be quite pure when it comes to IO - it doesn't
+do any IO directly on its own, but for the very little IO functionality it
+does as part of "basic interaction with paths" (like importing other
+`.nix` files), it goes through an `EvalIO` interface, which is provided to the
+Evaluator struct on instantiation.
+
+This allows us to be a bit more flexible with how IO looks like in practice,
+which becomes interesting for specific store implementations that might not
+expose a POSIX filesystem directly, or targets where we don't have a filesystem
+at all (like WASM).
+
+Using the `EvalIO` trait also lets `tvix-eval` avoid becoming too strongly
+coupled to a specific store implementation, hashing scheme etc[^2]. As we can
+extend the set of builtins available to the evaluator with "foreign builtins",
+these can live in other crates.
+
+Following this pattern, we started implementing some of the "basic" builtins
+that deal with path access in `tvix-eval`, like:
+
+ - `builtins.pathExists`
+ - `builtins.readFile`
+
+We also recently started working on more complicated builtins like
+`builtins.filterSource` and `builtins.path`, which are also used in `nixpkgs`.
+
+Both import a path into the store, and allow passing a Nix expression that's
+used as a filter function for each path. `builtins.path` can also ensuring the
+imported contents match a certain hash.
+
+This required the builtin to interact with the store and evaluator in a very
+tight fashion, as the filter function (written in Nix) needs to be repeatedly
+executed for each path, and its return value is able to cause the store to skip
+over certain paths (which it previously couldn't).
+
+Getting the abstractions right there required some back-and-forth, but the
+remaining changes should land quite soon.
+
+## Catchables / tryEval
+
+Nix has a limited exception system for dealing with user-generated errors:
+`builtins.tryEval` can be used to detect if an expression fails (if
+`builtins.throw` or `assert` are used to generate it). This feature requires
+extra support in any Nix implementation, as errors may not necessarily cause the
+Nix program to abort.
+
+The C++ Nix implementation reuses the C++ language-provided Exception system for
+`builtins.tryEval` which Tvix can't (even if Rust had an equivalent system):
+
+In C++ Nix the runtime representation of the program in execution corresponds
+to the Nix expression tree of the relevant source files. This means that an
+exception raised in C++ code will automatically bubble up correctly since the
+C++ and Nix call stacks are equivalent to each other.
+
+Tvix compiles the Nix expressions to a byte code program which may be mutated by
+extra optimization rules (for example, we hope to eliminate as many thunks as
+possible in the future). This means that such a correspondence between the state
+of the runtime and the original Nix code is not guaranteed.
+
+Previously, `builtins.tryEval` (which is implemented in Rust and can access VM
+internals) just allowed the VM to recover from certain kinds of errors. This
+proved to be insufficient as it [blew up as soon as a `builtins.tryEval`-ed
+thunk is forced again][tryeval-infrec] – extra bookkeeping was needed. As a
+solution, we now store recoverable errors as a separate runtime value type.
+
+As you can imagine, storing evaluation failures as "normal" values quickly leads
+to all sorts of bugs because most VM/builtins code is written with only ordinary
+values like attribute sets, strings etc. in mind.
+
+While ironing those out, we made sure to supplement those fixes with as many
+test cases for `builtins.tryEval` as possible. This will hopefully prevent any
+regressions if or rather when we touch this system again. We already have some
+ideas for replacing the `Catchable` value type with a cleaner representation,
+but first we want to pin down all the unspoken behaviour.
+
+## String contexts
+
+For a long time, we had the [working theory][refscan-string-contexts] that we
+could get away with not implementing string contexts, and instead do reference
+scanning on a set of "known paths" (and not implement
+`builtins.unsafeDiscardStringContext`).
+
+Unfortunately, we discovered that while this is *conceptually* true, due to a
+[bug in Nix][string-contexts-nix-bug] that's worked around in the
+`stdenv.mkDerivation` implementation, we can't currently do this and calculate
+the same hashes.
+
+Because hash compatibility is important for us at this point, we bit the bullet
+and added support for string contexts into our `NixString` implementation,
+implemented the context-related builtins, and added more unit tests that verify
+string context behaviour of various builtins.
+
+## Strings as byte strings
+
+C++ Nix uses C-style zero-terminated strings internally - however, until
+recently, Tvix has used standard Rust strings for string values. Since those are
+required to be valid UTF-8, we haven't been able to properly represent all the
+string values that Nix supports.
+
+We recently converted our internal representation to byte strings, which allows
+us to treat a `Vec<u8>` as a "string-like" value.
+
+## JSON/TOML/XML
+
+We added support for the `toJSON`, `toXML`, `fromJSON` and `fromTOML` builtins.
+
+`toXML` is particularly exciting, as it's the only format that allows expressing
+(partially applied) functions. It's also used in some of Nix' own test suite, so
+we can now include these in our unit test suite (and pass, yay!).
+
+## Builder protocol, drv->builder
+
+We've been working on the builder protocol, and Tvix's internal build
+representation.
+
+Nix uses derivations (encoded in ATerm) as nodes in its build graph, but it
+refers to other store paths used in that build by these store paths *only*. As
+mentioned before, store paths only address the inputs - and not the content.
+
+This poses a big problem in Nix as soon as builds are scheduled on remote
+builders: There is no guarantee that files at the same store path on the remote
+builder actually have the same contents as on the machine orchestrating the
+build. If a package is not binary reproducible, this can lead to so-called
+[frankenbuilds][frankenbuild].
+
+This also introduces a dependency on the state that's present on the remote
+builder machine: Whatever is in its store and matches the paths will be used,
+even if it was maliciously placed there.
+
+To eliminate this hermiticity problem and increase the integrity of builds,
+we've decided to use content-addressing in the builder protocol.
+
+We're currently hacking on this at [Thaigersprint](https://thaigersprint.org/)
+and might have some more news to share soon!

+     width="300"
+     style="filter: drop-shadow(1px 1px 6px grey);">
+
+*What*
+
+:    A week of intense hacking [on Nix](https://nixos.org/nix) in Kazan, the capital of Tatarstan in Russia.
+
+*When*
+:    22/08/2024 - 29/08/2024 (Thu - Thu)
+
+*Where*
+:    [Kazan, Tatarstan, Russia](https://yandex.com/maps/-/CDFaeW~J), on the bank of the [Volga](https://en.wikipedia.org/wiki/Volga)
+
+*Who*
+:    ~20 developers.
+
+Volga Sprint is similar to other Nix events like [Ocean Sprint](https://oceansprint.org/) and [Thaiger Sprint](https://thaigersprint.org/).
+
+## πŸ“ Location
+
+[Kazan, Tatarstan, Russia](https://yandex.com/maps/-/CDFaeW~J)
+
+Kazan is the historial capital of the Republic of Tatarstan. The city is over 1000 years old and is considered one of the main tourist destinations in Russia.
+
+Kazan is located on the bank of the Volga, the longest river in Europe, and surrounded by numerous lakes and beautiful nature.
+
+![Birds eye view of the Kazan Kremlin on the embankment](assets/kazan_overview.webp)
+
+As one of Russia's seven Muslim-majority republics, it offers a beautiful blend of Islamic architecture with traditional Russian styles.
+
+![Farmer's Palace in Kazan; enormous, beautiful building with a large tree growing in the central portcullis](assets/kazan_tree.webp)
+
+![Bauman Street; one of the central pedestrian areas of Kazan](assets/baumana.webp)
+
+For the sprint we will rent a large private house close to the centre of Kazan.
+
+## 🏘️ Accommodation
+
+Once we've determined who will attend the sprint, we'll get everyone to a shared chat room to help organise accomodation (e.g. shared apartment rentals). We'll also have some rooms available in the house that we're hosting the sprint in, but not enough for everyone.
+
+We will choose a house that is not too far from decent hotels and rentable apartments.
+
+Note that the sprint budget will *not* cover accommodation.
+
+## 🍲 Food
+
+During the sprint we'll take care of lunch in the house. For other meals, a large amount of good restaurants are available in Kazan (many of which work 24/7, which might help those who arrive with a jet-lag!).
+
+We'll try to have a recommended dinner location on most evenings, but everyone is of course free to do their own thing!
+
+## πŸ”₯ Registration
+
+[Fill out the form to apply](https://forms.yandex.ru/cloud/65e640fc73cee71ec679db66/).
+
+We're aiming to process applications as soon as possible and notify attendees in May.
+
+## 🧡 Topics
+
+The topics will depend on attendees' interest, in general anything related to Nix is fine! You should have a general idea of what you're interested in working on, but ultimate it is of course up to you.
+
+## πŸ›¬ How to get here
+
+Kazan has an international airport [with many connections](https://www.flightconnections.com/flights-from-kazan-kzn), including to hub airports like Istanbul (for connections to Europe), Dubai (for connections to ... everywhere) and directly flights to many Asian and Arab countries.
+
+Depending on where you're coming from a flight via Moscow or a more eastern location like Vladivostok might be preferable. Internal Russian flights are fairly cheap, and train rides are also a comfortable alternative (although they can be up to a week long - it's a big country!).
+
+### πŸ›‚ Visas
+
+Tatarstan is subject to standard Russian visa regulations. For citizens of most European[^1] (and many other) countries, a simple e-visa can be [applied for online](https://evisa.kdmid.ru/) and is valid for up to 16 days.
+
+Citizens of many non-Western nations[^2] can travel to Russia visa-free. Please make sure to check your particular situation.
+
+For everyone else (notably, Americans and Brits) a visa application at your local Russian embassy or visa centre is necessary. If you're approved for the sprint we're happy to help out with this!
+
+[^1]: **e-visas** available for citizens of Andorra, Austria, Bahrain, Belgium, Bulgaria, Cambodia, China, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Iran, Ireland, Italy, Japan, North Korea, Kuwait, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Malta, Mexico, Monaco, Myanmar, Netherlands, North Macedonia, Norway, Oman, Philippines, Poland, Portugal, Romania, San Marino, Saudi Arabia, Serbia, Singapore, Slovakia, Slovenia, Spain, Sweden, Switzerland, Taiwan, China, Turkey, Vatican, Viet Nam
+

+
+## πŸ₯³ Stuff to do in Kazan
+
+We'll organise a handful of group activities during the sprint and you can choose to attend the ones that are interesting to you! What exactly we're doing is not yet decided, but some options are things like:
+
+* Excursion to the Kazan Kremlin, including a visit to the Kul Sharif Mosque, one of the largest mosques in Europe
+* Evening sunset dinner on the bank of the Volga
+- Excursion to one of the crystal clear, blue lakes near Kazan
+* Evening visit to a traditional Russian *banya* (steam bath house)
+* Traditional Tatar cooking class (including how to make Chak-Chak)
+
+## πŸ’™ Sponsors
+
+We're looking for sponsors to cover expenses such as venue, catering, T-shirt printing and some of the activities.
+
+Please help us make this a productive event by chipping in, so we can focus on coding instead of grocery shopping and cooking.
+
+Our target budget is 500 000 RUB (~ 5000 EUR). Reach out to [sponsors@volgasprint.org](mailto:sponsors@volgasprint.org) or directly to tazjin.
