The video from the talk I gave on how to get more public visibility into DPRK consumer technology is now online.
Slides for the talk are available here.
I’m very excited to have two talks at CCC at the end of the month. The bulk of accepted talks can be seen and voted on at the CCC “halfnarp”.
The first talk is on the Internet in Cuba. It expands upon the recent talk I presented at IMC last month, to provide additional color on what Internet access is really like in Cuba, and what the community there is doing to create LANs and other alternatives to the official but expensive ETECSA service.
The second talk looks again at technology in Pyongyang. Since 2014, there have been a number of talks about the totally closed off tech ecosystem there, but as it ramps up we continue to only get a few glimpses into what’s going on, and it’s getting only harder as the broader tensions ramp up. My goal is to propose a path for getting more rather than less transparency into the picture, because it is a really fascinating place.
The talks should both be recorded, and might even be streamed. If you’re one of the (I hear it could be up 16,000) participants, I hope to see you in Leipzig!
It’s great to see that Research into Human Rights Protocol Considerations has been published as an RFC. An interesting document exploring how the technical protocols of the Internet interact with our real-world values.
I had the chance to visit China last week and tag along with the tail-end of a longer trip organized around various Makerspaces around the region. This is the first time in several years that I’ve spent a prolonged amount of time in the dense population areas of Beijing and Shanghai, and it was fascinating to watch the evolution that continues in this majority of Chinese life.
The most noticeable change from my perspective is that Beijing and Shanghai are effectively almost cashless. The use of Alipay and wechat pay are ubiquitous, to the point that you feel that you are creating an imposition to shop keepers by paying with cash. While funding your account on either of these services requires a chinese bank account (which itself requires a mainland cellphone number), the process can be short-circuited by making an unofficial exchange with someone willing to send you a personal transfer within the systems. It remains easy enough to find people at hostels, (as well as localbitcoins, I hear) who are willing to trade.
The systems themselves are fascinating to use. Payment to a merchant will automatically cause you to follow the merchants account, typically leading to messages about member cards and discounts. These messages seemed to only be pushed directly in response to a purchase, and weren’t overly intrusive. It seems to be the realization of the business-to-consumer engagement systems facebook and google have been struggling and so far failing to build in the US. Smaller vendors often operate directly as individuals – you type in how much money the bill is, and send it as a direct transfer to an account specified by the waiter or merchant.
This payment structure has resulted in a secondary industry of android-based devices dedicated to sales and scanning QR codes for these systems, as well as receipt printers that turn app orders into printed requests for food or similar.
Apart from the payment evolution, it is really interesting to watch China modernize. Life there now is much more comfortable from a western perspective than it has been in the past, with both a larger presence of foreigners visible and more english available to help navigate. Some distinctive characteristics remain, including a self-interested approach to queuing and different expectations of personal space. Prices in Shanghai have reached parity with those in the west, although cheaper options remain if you look for them.
In terms of Internet connectivity, I was surprised to find that connectivity remained quite similar to what I had experienced in the past. An SSH tunnel to a foreign server was sufficient to maintain email access while I was there, and disruptions I experienced seemed to be much more a function of over-loaded local networks than of more restrictions for international traffic. I talked with a couple different people who mentioned that Astrill continues to not be blocked, and seemed surprised that something so well known continues to operate without disruption.
Excited to see this work show up at IMC in November.
I’m excited that the first project I helped on at Michigan will be presented at FOCI next month: An ISP-Scale Deployment of TapDance
One of the more common password managers in linux environments is the gnome-keyring, which is split into a service (gnome-keyring-daemon), and a user interface (most commonly, seahorse).
After a bit of fiddling in the last couple weeks, this system can be compiled to run on a mac, with only a little bit of pain.
On the off chance that it saves someone some pain who’s trying to do the same thing, here are the basic steps I needed to take:
brew install autoconf automake dbus gettext gnome-icon-theme gobject-introspection gtk+3 gtk-doc intltool libffi libgcrypt libtool p11-kit pkg-config vala
brew install libsecret --with-vala
git clone https://github.com/GNOME/gcr
git apply 0001-patch-for-osx-compilation.patch
PATH=/usr/local/opt/gettext/bin/:$PATH ./configure --enable-valgrind=no --enable-vala=yes --disable-nls --prefix=/usr/local/opt/seahorse
git clone https://github.com/GNOME/gnome-keyring
PATH=/usr/local/opt/gettext/bin/:$PATH PKG_CONFIG_PATH=/usr/local/opt/libffi/lib/pkgconfig/:/usr/local/opt/seahorse/lib/pkgconfig/ ./configure --disable-valgrind --without-libcap-ng --disable-doc --disable-pam --disable-ssh-agent --disable-selinux --disable-p11-tests --disable-nls --prefix=/usr/local/opt/seahorse
PATH=/usr/local/opt/gettext/bin/:$PATH PKG_CONFIG_PATH=/usr/local/opt/libffi/lib/pkgconfig/:/usr/local/opt/seahorse/lib/pkgconfig/ ./configure --disable-ldap --disable-hkp --disable-sharing --disable-ssh --disable-pkcs11 --prefix=/usr/local/opt/seahorse/
To run, you’ll need to run these components connected by a DBUS instance.
The following script seems to accomplish this:
dbus-daemon --session --nofork --address=unix:path=$HERE/unix_listener &
GSETTINGS_SCHEMA_DIR=/usr/local/opt/seahorse/share/glib-2.0/schemas/ DBUS_SESSION_BUS_ADDRESS=unix:path=$HERE/unix_listener ./gnome-keyring/gnome-keyring-daemon --start --foreground &
GSETTINGS_SCHEMA_DIR=/usr/local/opt/seahorse/share/glib-2.0/schemas/ DBUS_SESSION_BUS_ADDRESS=unix:path=$HERE/unix_listener ./gcr/gcr-prompter &
GSETTINGS_SCHEMA_DIR=/usr/local/opt/seahorse/share/glib-2.0/schemas/ DBUS_SESSION_BUS_ADDRESS=unix:path=$HERE/unix_listener ./seahorse/seahorse
The Pyongyang University of Science and Technology (PUST) has shown up in a recent New York Times article, and I’m mentioned at the end.
A couple notes on the article:
Projects like PUST are an opportunity to put a human face on Americans in the minds of the next generation of educators and empowered thinkers in Pyongyang. It’s hard to overstate the value of that engagement.
I’ll be talking at Linux Fest Northwest in a couple weeks.
