Docker gentoo env recipe

May 10, 2019 — shinohai

This page is just a note on reliable ways to get a working gentoo environment using Dockerfiles. Useful mainly for making decent working shell that you don't care about for testing things. :)

The recipe can also easily be modified to use own stage3 and not be reliant on dockerhub, though abuse of the autobuild scripts sometimes spawns a shellbot over irc.

docker pull btcinfo/stage3-gentoo-amd64 docker run -it btcinfo/stage3-gentoo-amd64

This gives you a root shell

37b0f185b13d ~ #

Populate the portage tree with the latest official portage snapshot, or use your own archived snapshot.

cd usr/ wget -c http://distfiles.gentoo.org/snapshots/portage-latest.tar.xz tar xvf portage-latest.tar.xz

You can now emerge the packages you need and build from sources. Do what thou will.

Official Alpine Linux Docker image found to allow NULL password for root users

May 08, 2019 — shinohai

Docker woes continue as security researchers discover that all "Official images" of Alpine linux (since v3.3) allow NULL passwords for the root user. This event, along with Docker Hub being hacked serve as a wonderful reminder of only running code from trusted sources and personal libraries.

Converting magnet links to .torrent files in bash

May 02, 2019 — shinohai

I like simple things that do their job well, and I adore bash. A tool was sorely needed in my arsenal that could convert magnet links from torrent sites to a useable .torrent file. The site magnet2torrent.me is often down, and few options exist on the web to do convert files locally that aren't pythonshit. My search led me to a Shithub repository owned by Isis Buttcruft, and while the tool appears to work as advertised it has been neglected and is heavily commented and contains a few unnecessary parts. Let's trim it up a bit and make it a function.

magnet() { [[ "$1" =~ xt=urn:btih:([^&/]+) ]] || exit hashh=${BASH_REMATCH[1]} if [[ "$1" =~ dn=([^&/]+) ]];then filename=${BASH_REMATCH[1]} else filename=$hashh fi fn="meta-"$filename".torrent" touch $fn echo "d10:magnet-uri${#1}:${1}e" | cat > $fn }

Adding this to my .bash_aliases file now allows me to simply do `magnet "<URL>"` and get a torrent file instantly that can be loaded up into rtorrent or streamed using peerflix.

Building Unobtanium on Docker

April 17, 2019 — shinohai

This docker recipe has so far proved a stable way to get repeatable results when building Unobtanium binaries for 64-bit Linux and Windows. I am mainly making this post to reference the steps I took, as the method is applicable to most coins.

Download my unobtanium-devenv and untar it.

curl http://btcinfo.sdf.org/library/bitcoin/alts/uno/unobtanium-devenv.tar.gz | tar zxvf -

Enter devenv and build the docker image

cd unobtanium-devenv/

docker-compose -f docker-compose.yml -f unobtanium/docker-compose.windows.yml build

Go have a coffee and smoke while the container builds.

When that build finishes, start the container.

docker-compose -f docker-compose.yml -f unobtanium/docker-compose.windows.yml up -d

Find your container id and connect (as root)

docker container ls --all

docker exec -u root -t -i <container-id> /bin/bash

From the docker shell, go clone my Unobtanium repo.

git clone https://github.com/Shinoa-Fores/Unobtanium.git && cd Unobtanium/depends/

Let's do a Windows build, just for fun.

make HOST=x86_64-w64-mingw32

The process of compiling the dependncies takes about 2 hours. I usually also invoke `import colombian websluts` at this point. When I return to the terminal we are ready to build the UNO qt and cli .exe's

cd ..

./autogen.sh

./configure --prefix="$PWD/depends/x86_64-w64-mingw32/"

make

Kill another hour drinking coffee, smoking, and looking at cats on internet.

mkdir -p bin

cp src/*.exe bin/

cp src/qt/unobtanium-qt.exe bin/

Enjoy your shiny new Windows wallet. Repeat the depends step and rebuild to produce binary for any arch you have a config for.

The x86_64 Linux version lets you do nice things, like run custom .qss so I darkened the wallet. I will post this config to the blog shortly.

Have fun, and feel free to complain about this build method on irc or telegram.

Weechat logs to html

March 06, 2019 — shinohai

weechat-log-to-html is a Haskell script that converts weechat logs to no-nonsense html. This addition to the /library/ is part of this years goal to excise as much pythonshit as possible from everything I use on a regular basis. Individuals that have Bitlbee hooked up to their weechat will be pleased to know that this script also beautifully parses things such as telegram or discord logs, for which no suitable logger (at least not one written in the aforementioned pythonshit or nodejs) can be found.

To use:

Compile the script using `ghc` - I used version 8.0.2 with good results. Then simply run something like the following:

./weechat-log-to-html < (weechatlog) > output.html

Example output:

Once verified that it works for you, you can simply add the script to a cronjob to monitor the irc channels and other chats you wish to log.

TRB Keccak regrind - test results and notes

January 20, 2019 — shinohai

I had originally intended this to be a better version of the build instructions I mirrored from the foundation website, but decided to wait for the regrind before making a post, since the foundation planned on updating everything anyway. A few days later mod6 published a blog post detailing the steps he took to update the trb vtree from SHA512 to Keccak vpatches, so that is what will be covered in this post. What I did was, I went through all the similar steps just as in mod6's post, and I created my own keccak trb vtree, just as mod6 did. I then was able to confirm that my keccak trb vtree and his keccak trb tree are a mechanical match. I also did a diff of my keccak trb vtree against the original SHA512 vpatches, and we can see that only difference is the removal of the UTF8 character from genesis.vpatch.

You will need all of the dependencies listed on the bitcoin foundation website in the "how-to" section. A modified version of mod6's `v.pl` (that produces Keccak hashes) and a few other tools are also needed: these can be obtained from diana_coman's website. I no longer use nor support any other flavor of Linux besides Gentoo for any projects discussed on this site , so users of other distros will be required to do their own research to make all this work. I am using a Cuntoo chroot here, and for the sake of thoroughness, here is a list of the exact versions of the dependencies I used:

* sys-devel/bc 1.06.95-r2 * sys-devel/gcc 4.9.4 * app-crypt/gnupg 1.4.10 * net-misc/wget 1.19.5 * net-misc/curl 7.61.1 * dev-lang/perl 5.24.3-r1 * sys-devel/patch 2.7.6-r2 * net-misc/rsync 3.1.3 * sys-apps/coreutils 8.29-r1 * app-arch/unzip 6.0_p21-r2 * app-arch/bzip2 1.0.6-r10 * app-arch/cpio 2.12-r1

A working Ada setup is required to build vk.pl and the tools from diana-coman's starter pack. mod6 also wrote a handy and very detailed guide to doing this here. Since I am using a clean chroot to perform all these steps, I needed to install a new copy of Adacore, so I proceeded to grab a copy of the gnat-gpl-2016-x86_64 version from the AdaCore website here, though for some reason the page 404'd at the time I was doing these tests. Fortunately diana_coman also has this preserved on her website here for those that might need it in the future.

Once that was installed, I checked to ensure it was, in fact, the proper version:

Perfect! Building the starter pack is very painless and took less than a minute for me.

Now I moved on to the actual regrind by setting up the suggested sandbox and moving down the list of steps in mod6's blog post. This also went quite painlessly, my only snafu being I forgot to add back a hyphen "-" for the utf-8 char removed from line 118 of util.h, which caused a byte mismatch later in the process. Once that was done, I had no other problems with the process and was ready to test using mod6's experimental patchset and seals which he handily provides here, along with the signature for same. This part requires one follow the `OFFLINE` build steps from the foundation website, so it will be necessary to download the dependencies from deedbot if you don't have a copy stored somewhere already. I put all the links inside a bash script, intentionally leaving off the -sSL flags so I could observe their download progress.

cd deps/ cat >eu.sh<<EOF curl http://deedbot.org/deed-430460-2.txt > rotor.tar.gz.asc curl http://deedbot.org/deed-430460-1.txt > rotor-db-configure-fix.patch.asc curl http://deedbot.org/deed-422651-1.txt > boost_1_52_0.tar.bz2.asc curl http://deedbot.org/deed-422651-2.txt > buildroot-2015.05.tar.gz.asc curl http://deedbot.org/deed-422651-3.txt > db-4.8.30.tar.gz.asc curl http://deedbot.org/deed-422651-4.txt > openssl-1.0.1g.tar.gz.asc curl http://deedbot.org/deed-427443-1.txt > binutils-2.24.tar.bz2.asc curl http://deedbot.org/deed-427443-2.txt > busybox-1.23.2.tar.bz2.asc curl http://deedbot.org/deed-427443-3.txt > expat-2.1.0.tar.gz.asc curl http://deedbot.org/deed-427443-4.txt > fakeroot_1.18.4.orig.tar.bz2.asc curl http://deedbot.org/deed-427443-5.txt > gcc-4.9.2.tar.bz2.asc curl http://deedbot.org/deed-427443-6.txt > gdb-7.8.2.tar.xz.asc curl http://deedbot.org/deed-427443-7.txt > gmp-6.0.0a.tar.xz.asc curl http://deedbot.org/deed-427443-8.txt > linux-3.18.14.tar.xz.asc curl http://deedbot.org/deed-427443-9.txt > m4-1.4.17.tar.xz.asc curl http://deedbot.org/deed-427443-10.txt> mpc-1.0.3.tar.gz.asc curl http://deedbot.org/deed-427443-11.txt> mpfr-3.1.2.tar.xz.asc curl http://deedbot.org/deed-427443-12.txt> musl-1.1.8.tar.gz.asc curl http://deedbot.org/deed-427443-13.txt> ncurses-5.9.tar.gz.asc curl http://deedbot.org/deed-427443-14.txt> pkgconf-0.8.9.tar.bz2.asc EOF chmod +x deps.sh ./deps.sh

After enjoying un cafecito, the dependencies were finished downloading, so I deleted the script and changed back to the bitcoin directory. A simple `make` completes the process. I encountered no hiccups, and roughly a half hour or so later had a nice shiny bitcoind produced using vk.pl and the keccak patchset only.

In the interests of science, and to ensure repeatable results I went a step further and redid all the regrind steps in a fresh sandbox, and signed a copy of all the patches with my gpg key. Before performing a press I put mod6's copy of the patches in a directory `a` and mine in a directory `b` and ran `diff -uNr a b` against them to ensure they matched, which they did. This build also went fine with no errors, and output a 4.7M to bin/. Now let's test it:

Success! Node is happily pulling blocks.

In conclusion, this work represents an outstanding effort on the part of mod6 to ensure trb remains unmolested in the future. I have uploaded my copies of the resulting patches and the corresponding seals here for those that wish to compare them with their own during testing.

Building the Eulora client with Gentoo

January 11, 2019 — shinohai

Having gotten trinque's excellent Cuntoo bootstrap working on a few different machines, I decided I'd try building a Eulora client with it. This post is to document the steps I followed to get to a working state, as the instructions on the minigame website are outdated and contain dead links.

In this guide, I am using gcc 4.9.4 - I'm pretty sure this is a hard requirement. Crystalspace for whatever reason requires you have the nvidia-cg-toolkit installed even if you use an ATI card, so go ahead and get that via portage:

emerge -av nvidia-cg-toolkit

I have a ~/devel directory already from building trb, so I'll start there and make a eulora directory beside it:

mkdir -p eulora/ && cd $_

Grab cal3d, crystalspace, and the Eulora client files from the minigame site:

wget http://minigame.biz/eulora/source/cal3d.tar.gz
wget http://minigame.biz/eulora/source/cs_July24.tar.gz
curl http://minigame.biz/eulora/source/eulora-v0.1.2b.tar.gz > eulora-v0.1.2b.tar.gz

Untar that shit.

tar -zxvf cal3d.tar.gz
tar -zxvf cs_July24.tar.gz
tar -zxvf eulora-v0.1.2b.tar.gz

Navigate to cal3d/ and run the following commands to build:

autoreconf --install --force
./configure --prefix=$HOME/devel/eulora/cal3d
make
make install

Tell other programs where to find the cal3d things we just built:

export LD_LIBRARY_PATH=$HOME/devel/eulora/cal3d/src/cal3d/.libs/:$LD_LIBRARY_PATH

Go back to ~/devel/eulora/ and enter the cs-forupload folder:

cd ../cs-forupload/

To build crystalspace I had to adjust the configure step to avoid anything bullet related, or the jam build step will barf. Use the following commands:

./configure \
--without-java \
--without-perl \
--without-python \
--without-3ds \
--without-bullet \
--with-cal3d=/$HOME/devel/eulora/cal3d

jam -aq libs plugins cs-config walktest

Export the crystalspace environment variable:

export CRYSTAL=$HOME/devel/eulora/cs-forupload

Finally, go back to ~/devel/eulora/ and enter the EuloraV0.1.2 folder ...

cd ../EuloraV0.1.2/

...and build the client:

./autogen.sh
./configure \
--with-cal3d=$HOME/devel/eulora/cal3d \
--with-cs-prefix=$CRYSTAL \
--without-mysqlclient \
--without-sqlite3 \
--without-pq \
--without-hunspell

jam -aq client

Eulora servers got a new home in 2018, so we must edit the server ip in data/servers.xml:

sed -i 's/50.115.127.84/161.0.121.201/' data/servers.xml

Now, to avoid having to manually enter the environment variables each time we want to play, we will create a shell script containing those and make it executable:

cat >eu.sh<<EOF
export LD_LIBRARY_PATH="$HOME/devel/eulora/cal3d/src/cal3d/ \
.libs:$HOME/devel/eulora/cs-forupload/:"$LD_LIBRARY_PATH
export CRYSTAL=$HOME/devel/eulora/cs-forupload
./euclient
EOF

chmod + eu.sh

./eu.sh

It was night in Eulora when I finished, so I only took a single screenshot of client startup. More to come as I test further.

May your journey be prosperous ....

Handheld game roms

While searching for the Basic games collection the other day, I stumbled upon a forgotten archive containing roms for a bunch of old handheld electronic games from the 70's and 80's.

Basic Computer Games

December 23, 2018 — shinohai

Old computer nostalgia often hits some of us hard on Telegram, and hours will be spent in conversation or reliving the glory days of TRS-80 and Commodore64 machines. In one such conversation, I mentioned I had a tarball somewhere of all the programs in the old 1978 book "Basic Computer Games" published by Creative Computing. After a brief search, the package was located and I decided to uploaded it to the /warez/ section of the library for others to enjoy - whether you are painfully typing these in line by line in original hardware or loading them with an emulator, I hope the collection brings back lots of pleasant memories for those of us that still enjoy tinkering with these things. Most of these I can verify still indeed work well on original hardware: I loaded many of these into my old TRS80 using a HxC2001 SD floppy emulator (because I'm lazy and didn't want to hand type them all) and ran with 0 syntax errors.

Table of games included in the archive:

bcinfobot

December 06, 2018 — shinohai

bcinfobot is a common lisp bot that bridges irc and telegram, and performs a variety of mostly useless crypto stats. It currently resides in the #btcinfo channels on freenode irc and telegram.

IRC command prefix is `$` - You must have a registered gpg key to use this bot.

This post will be updated as soon as comprehensive list of all commands can be added. Discussion is currently more vibrant on telegram, and discord support has been requested.

Cuntoo, a Linux that sucks less

December 02, 2018 — shinohai

This weekend I had a bit of extra time on my hands, so I decided to dust off an old AMD E-300 APU laptop I had sitting about and try building trinque's Cuntoo on it. The entire operation was pretty straightforward, and the bootstrapping script makes all this a painless operation as far as Gentoo goes.

First step is to download the bootstrap in a tar archive and the corresponding signature from here: http://trinque.org/2018/11/27/cuntoo-bootstrapper/ . It appears the site is hosted on pizarro now, and downloading the archive took a little over 2 hours. Since I am quite aware that Pizarro resources can be overwhelmed with a single box making requests, I just left this to download overnight and checked on it in the morning. trinque has his head screwed on pretty straight, so the archive and sig were waiting in my Downloads folder after morning coffee.

After examining the bootstrap script, I put a copy of my amd64 configuration file into the config/ folder, since I don't have an apu2 board. One then needs to locate the block device they will be installing to, in my case `lsblk` revealed this to be located at /dev/sdc, so I ran: `./bootstrap.sh -k config/config.amd64 -d /dev/sdc` .... and the magic began! The author recommended enjoying tea whilst the bootstrap process completed. The entire process took roughly six hours to complete, which will give one time to enjoy their favourite beverage and a fuck or two. When I came back to my desk I was greeted with the message "Create a user account, which shall be granted sudo access." After that, the script will ask you to paste a ssh public key in, to allow password free logins upon reboot. Painless, I say!

Those steps being complete, I got one final message: "You should now have a fully bootable Cuntoo system on "/dev/sdc". Enjoy!" The moment of truth. I then restarted the machine which booted very quickly into a new, no-nonsense Gentoo Linux environment.

Since the first run was successful, I decided to see how this recipe would work if I stuffed it onto a spare 32G flash drive I had lying about. This also worked fine, and now I have a portable version I can access via chroot on my workstation, since I have a less austere Gentoo recipe I use for day-to-day things.

I now intend to try running the ebuilds I have made for the projects I use most against this, and will report my findings here. Happy compiling!

Bitcoin Knots restored as the default upstream ebuild

July 22, 2018 — shinohai

Bitcoin Knots is once again the default ebuild of Bitcoin for Gentoo users. In order to revert to the "Core" flavor of Bitcoin, users will need to set the USE=-knots flag going forward.

According to developer luke-jr in a recent announcement:

Bitcoin Knots provides the best end user experience out of the box (for example, only 5 GB disk space is required instead of over 100 GB). It is completely compatible with the Bitcoin network and other Bitcoin implementations, including the popular Bitcoin Core implementation.

Bitcoin knots is currently undergoing testing on the btcinfo server, and will serve as a replacement for "therealbitcoin" in irc/telegram bot functions that require bitcoind. Source code and relevant patches will be added to the /bitcoin/ section of this website in the near future.

UPDATE 7/24/2018: luke-jr informed me that the these changes have not been merged yet. I apologize for the misquote.

Reading the #trilema logs this morning, it seems this post created fair amount of confusion:

asciilifeform: in other lulz, http://btcinfo.sdf.org/blog/bitcoin-knots-restored-as-the-default-upstream-ebuild.html << shinohai endorses prb...

Please note the words undergoing testing, which should not imply any sort of endorsement or glowing review. To clarify, Knots simply offers some interesting features I want to poke with a stick more to satiate my curiosity - this segshit stuff is in wide use on alt irc platforms (Telegram, Discord, et all) and I simply want to see if any brokenness can be readily exposed. Sometimes that requires milling about in enemy territory and becoming familiar with enemy tools. Remember your Sun Tzu:

"If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle."

asciilifeform is welcome to go ahead and negrate - this has nothing to do with spite, etc. as you already know all about. Ratings in a place where one's presence is not wanted mean little to me at this point. Experiments fail sometimes, but work should always continue nonetheless.

After all, I can't simply idle about on the beach every day. There's a goddamned war going on.

AUR latest victim of repository rape

July 10, 2018 — shinohai

More poisoned repositories are found, this time on the Arch User Repository. This, combined with the recent lulz on the gentoo shithub further confirm that only the trinque model can prevent repository rape.
