 Very, very early in my self-improvement journey, I tried adding a 20 minute timer to my life. Every 20 minutes of my waking life, it went off. I’d explicitly say to myself what it was I was doing (“Watching TV” or “Talking to Fred”). It’s important to have a verbal or written note of what you’re doing.

@@ -23,5 +23,3 @@ The basic 20-minute check-in process was very helpful to me. Some benefits:
 -   **What am I doing, and do I want to be doing it?** Interrupting default activities (a type of inertia). Watching TV until I get bored of it takes me 2-10 hours, if I don’t have a timer. Having a timer interrupt me let me say “well, maybe this will be the last episode, then.” It’s easy to get into a low-energy state for leisure activities where you don’t notice the passage of time. And it’s important to note, I don’t have any rules. I can keep watching TV all night if I want to. This helps me avoid doing it out of pure inertia. (It also really keyed me in that TV does not really “recharge” my batteries. Other relaxation is better.)
 -   **Do I want to be doing it, or doing it this way?** Interrupting bad approaches (a type of inertia). Sometimes, I get stubborn. I’ll keep trying to solve a problem in one way, for way too long. Having a regular interruption keys me into how long I’ve been doing that. I’ll notice I should maybe try a different approach or a work-around. Or give up.
 -   **Ding!** Providing a check-in. I’ll just take stock, and say “hey, am I really having fun? is this even useful?”. Sometimes I’m just doing something dumb. Or sometimes I forget to have fun or take a break for too long. This is my reminder to check in with my strategic system; my emotions; my body.

 I also playtested “No this cannot be! I AM INVINCIBLE!”. It ran about 45 minutes prep (not fun) and 45 minutes playtime, which was the main problem. Overall the play time was fun. I rewrote it to have MUCH easier prep, and for the game to be generally easier. I also re-wrote the rules of “Ninjas Ninjas Ninjas” without a playtest. I don’t think it will ever be too popular but it has a soft spot for me.

 Now you’re back where you left off. My question is, *how?* How does nano remember what used to be on screen? How does it get restored? Is nano doing this, or bash?
 
-Well, I took at look at the [source code][4] to *nano*. Then I thought, “whoa! that’s way too complicated.” So I found a much simpler project called *ted* someone made to educate themselves. That was [also][5] a little complicated, but both seemed to use ncurses. So I wrote the following simple program, which *also* displays something and then restores the screen. Even though it’s very simple, it still works.
-
-    // Compile with: gcc -lncurses editor.c -o editor
-    
-    #include <curses.h>
-    #include <stdio.h>
-    
-    int main(int argc, char **argv) {
-        initscr();
-    
-        refresh();
-        printw("Hello world");
-        getch();
-    
-        endwin();
-        return 0;

+Well, I took at look at the [source code](https://github.com/madnight/nano/blob/master/src/nano.c) to *nano*.

 Aha, so it’s something in ncurses, maybe. Let’s dive deeper.
 
 So *initscr()* presumably saves the state in some fashion. *endwin()* definitely restores it, because if we comment that out, the terminal stops being restored. Since *initscr()* probably does lots of other irrelevant logic, we could take a look at *endwin()* to dive in. But let’s do something even simpler first.
 
-As background, the linux command line is pretending to be an obsolete piece of hardware called a [terminal][6]. Specifically, it’s pretending to be a model called the DEC VT100 (or a later one, but they’re mostly backwards compatible). The terminal accepted text over a wire, and printed it to the screen.
+As background, the linux command line is pretending to be an obsolete piece of hardware called a [terminal](https://en.wikipedia.org/wiki/Computer_terminal). Specifically, it’s pretending to be a model called the DEC VT100 (or a later one, but they’re mostly backwards compatible). The terminal accepted text over a wire, and printed it to the screen.
 
 When it got special text, it would do special things. These are captured today as “escape codes”–special non-printable characters, which cause your software terminal to also do special things. What kind of special things? Well one example escape code is “Backspace”, which deletes the last character. Another code is “\\r\\n” (carriage return; new line), which goes to the beginning of the line, and down one.
 
 I suspect the answer to what’s happening with save and restore of my terminal might be some magic escape codes. So let’s just redirect the output to a file, and see what data is being center over the virtual wire to our virtual terminal.

 Well, that’s certainly a bunch of magic. Now something cool happens:
 
-    $ cat magic.txt
+```
+$ cat magic.txt

 This command does *nothing visible*. It doesn’t print “Hello world”, even though that’s in the file. In other words, it’s printing Hello world, then really quick resetting the terminal. Just too fast for my poor human eyes to see.

 OK, solved. The magic save bytes are **1b 9b 3f 31 30 34 39 68** (<ESC> \[?1049h). The magic restore bytes are **1b 9b 3f 31 30 34 39 6c** (<ESC> \[?1049l). And xterm or tmux is doing the save/restore magic, based on seeing this escape mode.
 
 Hmm, how minimal can we get a working file, I wonder?
 
-    #!/bin/sh
-    echo -ne '\x1b[?1049h' # Save terminal
-    echo -ne '\x1b[H'      # Home the cursor

 Every year, the libera IRC network has a puzzle contest starting on 04-01. (It’s not an april fools joke). It’s fun but quite difficult.
 
 This year I wrote about a third of the puzzles. Give them a try, either alone or as a team! It will be open indefinitely, but social activity will die off in a week or two.
 
 As of writing, no one has won (finished all the puzzles) just yet.

 6.  Set up any browers, etc to use localhost:18000 as your proxy. You could also do some kind of global firewall config. Chromium in particular was pretty irritating on Arch Linux. It doesn’t respect $http\_proxy, so you have to pass it separate options. This is also a good point to make sure anything you don’t want recorded BYPASSES the proxy (for example, maybe large things like youtube, etc).

 Despite being semi-unmaintained, everything mostly works still. There were two exceptions–some major design problems around private repos. I only need to back up my public repos really, so I ‘solved’ this by issuing an Oauth token that only knows about public repos. And second, a small patch to work around a bug with User objects in the underlying Github egg:

It stores the tweets in a JSON format which presumably matches the API return values. Usage is simple:
 
 while read account

-I ran into a bug with [upstream incompatibilities][5] which is easily fixed. Another caveat is that the twitter API only allows access 3200 tweets back in time for an account–all the more reason to set up archiving ASAP. Twitter’s rate-limiting is also extreme ([15-180 req/15 min][6]), and I’m [worried about][7] a problem where my naive script can’t make it through a list of more than 15 accounts even with no updates.

 The contents of  /usr/local/bin/phone-backup are pretty me-specific so I’ll omit it, but it copies /media/android over to a server. (fun detail: MTP doesn’t show all information even on a rooted phone, so there’s more work to do)

 I basically had some long cardboard boxes, and cut them in half. Then I added new ends and separators in the middle.
 
 I’m not sure if they’ll actually get used. Mail on the floor looks bad, but these aren’t that hot either. If you make some and want to improve the look, you can cover everything in paper or cardstock.

 1.  It costs them money (*bandwidth*). Or, it makes the site unusable because too many “people” (all you) are trying to access it at once (*congestion*). Usually, it costs them money because the scaper is *stupid*–it’s something like a badly written search engine, which opens up every comment in a blog as a separate page, or opens up an infinite series of pages. For example, I host a bunch of large binaries (linux installers–big!), and I’ve had a search engine try to download every single one, once an hour. As a scraper, you can can avoid causing these problems by
     -   rate-limiting your bot (ex. only scraping one page every 5-10 seconds, so you don’t overload their server). This is a good safety net–no matter what you do, you can’t break things too badly. If you’re downloading big files, you can also rate-limit your bandwidth or limit your total bandwidth quota.
     -   examining what your scraper is doing as it runs (so you don’t download a bunch of unncessessary garbage, like computer-generated pages or a nearly-identical page for every blog comment)
-    -   obeying [robots.txt][1], which you can probably get a scraping framework to do for you. you can choose to ignore robots.txt if you think you have a good reason to, but make sure you understand why robots.txt exists before you decide.

     -   testing the site while you’re scraping by hand or with a computerized timer. If you see the site do something like load slower (even a little) because of what you’re doing, stop your scraper, and adjust your rate limit to be 10X smaller.
     -   make your scraper smart. download only the pages you need. if you frequently stop and restart the scraper, have it remember the pages you downloaded–use some form of local cache to avoid re-downloading things. if you need to re-crawl (for example to maintain a mirror) pass if-modified-since HTTP headers.

 In my personal opinion, suing people or bringing criminal charges does not work in general, because most people scraping do not live in the USA, and may use technical means to disguise who they are. Scrapers may be impossible to sue or charge with anything. In short, a policy of trying to sue people who scape your site, will result in your site still being scraped. Also, most people running a site don’t have the resources to sue anyone in any case. So you shouldn’t expect this to be a common outcome, but basically a small percentage of people (mostly crackpots) and companies (RIAA and publishers) may.

 They got 23, so I gave them all four scraps. They taped it back together and got the whole handout.
 
 And they remembered that handout. They told players *in other campaigns* about the handout.

 The final keyboard has 6 x 3 = 18 “keys”. We write the hex digits plus a couple extra keys with marker.
 
 If I attach alligator clips to the second horizontal screw terminal, and fourth vertical screw terminals, and wire a battery and buzzer with the terminals, I get a connection beep only when I press the key “A”:

 In a real computer, we obviously can’t just move alligator clips around. Instead, we attach wires to all 9 posts–three outputs wires for the horizontal lines, and six inputs for the vertical lines. We output a signal on the first horizontal line, and see if we can read it from any of the six vertical lines inputs. Then we output a signal on the second horizontal line, and see if we can read it, and so on for the third. Assuming only one key is pressed (or none), we can identify the key. This “scanning” process could be done thousands of times a second, rapidly enough that it can’t miss our slowpoke human fingers.

 This was my third attempt. Here’s the second, using aluminium foil. It worked at least as well, maybe better, but it was harder to make. I just taped the foil down, taking care not to cover the contact points. I am told the aluminium will gradually oxidize, making it non-conductive.

-    “And better keyboards can detect multiple keys being pressed at once (N-key rollover), which I think they do by having a completely separate wire to each key.”

-    You can keep a matrix arrangement and have N-key rollover by putting a diode in series with every switch

Here’s a video of it in action. It operates at one frame per second.

 The electronics are not fully done. They need better secured, and I’m going to redo the cabling and power back.

 I broke a screen over-tightening a nut. That said, I like this look pretty well! If the lid was thicker, I know how to avoid screws on the other side, too.

 I found a really nice, cheap mechanical keyboard on ebay. The main downside is that it’s heavy–730g. It also consumes heavy amounts of power, even when not in use. I have a nearly identical keyboard that doesn’t, which I’ll use for v2.

 The prototype is powered by a Raspberry Pi 3. The final version will use a microcontroller to save power. The Pi Zero can also be swapped in with no changes, and uses a third of the power. But it’s noticeably slower and takes 30 seconds to boot. For prototyping I’m using the Pi 3 for now.

+sudo mkfs.ext4 /dev/sdae # Make a filesystem directly on the device. No partition table.
+sudo blkid /dev/sdae # Make a note of the filesystem UUID for later
+```
 
 Next, we’ll generate a key.
 
-    sudo mount /dev/sdae /mnt
-    sudo dd if=/dev/urandom of=/mnt/root-disk.key bs=1000 count=8
+```
+sudo mount /dev/sdae /mnt
+sudo dd if=/dev/urandom of=/mnt/root-disk.key bs=1000 count=8
+```
 
 Add the key to your root so it can actually decrypt things. You’ll be prompted for your password:
 
-    sudo cryptsetup luksAddKey ROOT_DISK_DEVICE /mnt/root-disk.key
+```
+sudo cryptsetup luksAddKey ROOT_DISK_DEVICE /mnt/root-disk.key
+```
 
 Make a script at /usr/local/sbin/unlockusbkey.sh
 
-    #!/bin/sh
-    USB_DEVICE=/dev/disk/by-uuid/a4b190b8-39d0-43cd-b3c9-7f13d807da48 # copy from blkid's output UUID=XXXX
-    
-    if [ -b $USB_DEVICE ]; then
-      # if device exists then output the keyfile from the usb key
-      mkdir -p /usb
-      mount $USB_DEVICE -t ext4 -o ro /usb
-      cat /usb/root-disk.key
-      umount /usb
-      rmdir /usb
-      echo "Loaded decryption key from USB key." >&2
-    else
-      echo "FAILED to get USB key file ..." >&2
-      /lib/cryptsetup/askpass "Enter passphrase"
-    fi
+```
+#!/bin/sh
+USB_DEVICE=/dev/disk/by-uuid/a4b190b8-39d0-43cd-b3c9-7f13d807da48 # copy from blkid's output UUID=XXXX
+
+if [ -b $USB_DEVICE ]; then
+  # if device exists then output the keyfile from the usb key

+  rmdir /usb
+  echo "Loaded decryption key from USB key." >&2
+else
+  echo "FAILED to get USB key file ..." >&2
+  /lib/cryptsetup/askpass "Enter passphrase"
+fi
+```
 
 Mark the script as executable, and optionally test it.
 
-    chmod +x /usr/local/sbin/unlockusbkey.sh
-    sudo /usr/local/sbin/unlockusbkey.sh | cmp /mnt/root-disk.key
+```
+chmod +x /usr/local/sbin/unlockusbkey.sh
+sudo /usr/local/sbin/unlockusbkey.sh | cmp /mnt/root-disk.key
+```
 
 Edit /etc/crypttab to add the script.
 
-    root PARTLABEL=root_cipher none luks,keyscript=/usr/local/sbin/unlockusbkey.sh
+```
+root PARTLABEL=root_cipher none luks,keyscript=/usr/local/sbin/unlockusbkey.sh
+```
 
 Finally, re-generate your initramfs. I recommend either having a live USB or keeping a backup initramfs.
 
-    sudo update-initramfs -u
+```
+sudo update-initramfs -u
+```

 Fabric is a system administration tool used to run commands on remote machines over SSH. You program it using python. In 2018, Fabric 2 came out. In a lot of ways it’s better, but it’s incompatible, and removes some features I really need. I talked to the Fabric dev (bitprophet) and he seemed on board with keeping a Fabric 1 package around (and maybe renaming the current package to Fabric 2).

+Here’s an arch package: [https://aur.archlinux.org/packages/fabric1/](https://aur.archlinux.org/packages/fabric1/)
 
 Currently Fabric 1 runs only on Python2. But there was a project to port it to Python 3 (confusingly named fabric3), which is currently attempting to merge into mainline fabric. Once that’s done, I’m hoping to see a ‘fabric1’ and ‘fabric2’ package in all the main distros.

 -   I should have spent even more time on an easy-to-cut font. The “a”, “e”, and “r” are too hard in this font.

 This is a blank “subway” style marble tile. It’s 140×45 mm (2×6 inch). One is about $1. Avoid “glazed” or “glossy” tiles, which are too smooth for the paint to stick well.

 I’m on Linux, and here’s what I did to get the **Adafruit Pro Trinket** (3.3V version) to work. I think most of this should work for other Adafruit boards as well. I’m on **Arch Linux**, but other distros will be similar, just find the right paths for everything. Your version of udev may vary on older distros especially.

 Today I wrote a simple raytracer. A raytracer is a very simple way to draw excellent graphics. For each pixel, it follows an imaginary “line” out from the viewer through that pixel into the computer world. Then it colors the pixel based on what the line hits. Unfortunately, it also takes a lot of computing power.

 Matte spheres in different shades of grey. The blue in the spheres is reflected from the sky.
 
 The motivation for this project was to learn how to make things run faster on a graphics card. I quickly realized (before I wrote a line of code) that I’d need the basic raytracer to be its own project. Having it run faster will have to be a job for another day!

 Today I learned how to make PCBs. I didn’t invent anything here, this is all pretty well known by the PCB-making community, but it’s not well-known to *me*. So I taught myself a bit!

 To my surprise, after a little jiggling I got it down to a one-layer design.

 That means home-printing would be much easier. No having to line up the two sides carefully.

 I printed out the image on paper (backwards) on my toner printer, and taped it to the copper-clad PCBs.

 First, I tried laminating it. Almost no ink transferred, and the paper came off easily. Then I tried ironing it, but the paper stick to the iron and not to the PCB. The tape melted on the iron. For both, I dunked them in water after, which is supposed to help loosen the paper.

 Next, I tried the standard advice–sand the PCBs (I used 320 grit) and use glossy paper. This time, both pieces of paper stuck very well. I was wary about the iron coming off again, so I just left it on place on the highest heat–this worked fine for adhesion, but I had to iron out wrinkles at the end. The laminated piece had lose edges, while the ironed piece was on there totally flat.
 
 I tried peeling off the laminated paper–oops! It peeled back and most of the ink stayed on the paper. I think if I took it off more carefully, it would have worked.

 I picked at the ironed paper a bit, but it didn’t budge. I let it sit in dish soap for a while so the paper would fall apart. The first hour didn’t do anything.

 Meanwhile, I made an order at PCBWay. It’s still under review.
 
 Edit: after some advice from a friend, I peeled off this paper more aggressively, and scrubbed it off. The ink was fine. It doesn’t look great, but I think this is mostly the wrinkles during transfer. It’s a little blurry, I’ll have to do a third attempt before I try etching.

 My main goal with this project was to work with spritesheets or animation before, which I had never done. Showing off the individual tiles is deliberate. Also, the game should respond well to smaller and larger screens, I hope.
 
 I had a good time with this one, and I’m happy with how much I got done in a day. I originally planned to do more fluid walking (it was called Hack-A-Walk), but it was more fun to add crops instead.
 
 I re-used some of the logic from Hack-A-Minigame and Hack-A-Snake. I’ve been finding d3 to be mildly useful, if a little annoying.

 **Hack-A-Hang is NOT WORKING.**
 
 Unfortunately while everything works great on my machine, there’s a bad problem in production, and I ran out of time on this one. I’ll try to get it fixed before the end of the month if it’s easy.

 Hoo boy, this was one of the technically hardest ones so far. WebRTC is no joke. And not hard in a way where you have to think, hard in a way where the debugging tools are terrible. (Drag and drop was another tough one)

 I’m happy with this one, although it took way too long given yesterday’s project! I keep thinking I’ll be able to modify or re-use things quickly, and it’s not true.
 
 P.S. Taking the next day or two off for thanksgiving

 This is my first failure, which I think is good! I was getting bored only attempting things I could definitely succeed at in one day. That said, running out of time is fun. Wrestling the IDE isn’t. This was mostly wrestling the IDE, setting configs, and installing software.
 
 I won’t continue this tomorrow, I’d rather do a new project each day (It’s called Hack-A-**DAY**)! But I might do another Unity3D project before the month is out.

 Takeaways
 
@@ -341,132 +393,3 @@ Takeaways
 -   Email was REALLY not designed to do authentication, which is why proving you’re not a spammer is so difficult. This would all be trivial with decent crypto baked in (or really, almost any backwards-incompatible change)
 -   The option to specify a SQL query as a configuration file option is wonderful. Thanks, Dovecot.
 -   Overall, although it was a lot of work, I do feel like it was worth it to run my own email server.

+A friend of mine, [Kragen Javier Sitaker](http://canonical.org/~kragen/) has been designing something he calls the zorzpad (see link below). I can never remember the name, so as a joke my version became the “zorch pad”. We live on opposite sides of the globe, but we’ve picked up the same or similar hardware, and have been having fun developing the hardware and software together.
 
-The basic idea of the Zorchpad is to have one computer, indefinitely. It should keep working until you die. That means no battery that runs out, and no parts that go bad (and of course, no requirements to “phone home” for the latest update via wifi!). This is not your standard computer, and we’ve been trying a lot of experimental things. One of the main requirements is that everything be very low-power. He picked out the excellent [apollo3][2] processor, which theoretically runs at around 1mW. In general, the zorchpad is made of closed-source hardware.

In general, the zorchpad is made of closed-source hardware.
 
 Since I’ve realized this will be a long project, I’m going to post it piece-by-piece as I make progress. Below is a demo of the display.

 The graphics demo shows, in order:
 
 -   a title screen
 -   a flashing screen (to show graphics-mode framerate)
--   a demo of font rendering. we’re using the fixed-width font [tamsyn][3].
--   a [munching squares][4] animation

 -   a demo of how fast “text-mode” updates would be
 
-We’re using a [memory-in-pixel LCD][5]. The only manufacturer is Sharp LCD. You have have seen these before in things like the Pebble watch–they’ve very low-power except when you’re updating. This particular screen is quite tiny–240x400px display (which is fine with me), but only 1.39×2.31 inches (35x59mm). The only bigger screen available in this technology is 67x89mm, a bit lower resolution, and out of stock. As soon as it’s in stock I plan to switch to it.
+We’re using a [memory-in-pixel LCD](https://www.sharpsde.com/products/displays/model/ls027b7dh01/#productview). The only manufacturer is Sharp LCD. You have have seen these before in things like the Pebble watch–they’ve very low-power except when you’re updating. This particular screen is quite tiny–240x400px display (which is fine with me), but only 1.39×2.31 inches (35x59mm). The only bigger screen available in this technology is 67x89mm, a bit lower resolution, and out of stock. As soon as it’s in stock I plan to switch to it.
 
 According to the datasheet, the screen consumes 0.05-0.25mW without an update, and perhaps 0.175-0.35mW updating once per second. We haven’t yet measured the real power consumption for any of the components.
 
 The most obvious alternative is e-ink. E-ink has a muuuch slower refresh rate (maybe 1Hz if you hack it), and uses no power when not updating. Unfortunately it uses orders of magnitude more power for an update. Also, you can get much larger e-ink screens. The final zorchpad might have one, both or something else entirely! We’re in an experimentation phase.

-    Very cool idea. I was imagining form factors, and was thinking briefly about somehow having a sort of laptop arrangement where an e-ink screen is visible through glass when it is closed and in some kind of “protective storage mode”, and then visible directly from “the proper side of the e-ink screen” after it opens up. This is probably impossible using default hardware options, but searching around to confirm this lead to some interesting links and unusual design demos.

-    One thing that struck me is that a lot of people might want a Xorchpad to stick INSIDE a larger system (out in nature? as part of a science package?) that might install a rugged solar panel and battery. Then a small USB-C cord might provide a Xorchpad inside the unit with power, and want some intelligence to come out of the same cord, in exchange?
-    
-    I’m not sure if a USB-C is consistent with the vision, however. Maybe the “minimum power” for that is far above the “maximim power” that would not blow the Sourcepad’s circuits?

-        Try using numbers, instead of words! It works better for comparing power usage.
-        
-        The “low-power computer” someone wants from 12 years ago should be 3W. The Zorchpad is designed to run at 0.001W.
-        
-        I’m not sure what GVUIDO has to do with anything, was there a reason you linked that?
-        
-        The Zorchpad could easily be powered by any standard cable, yes. But if you need a larger system to power it, you’re missing the point.
-        
-        “Blowing circuits” is not a correct intuition for designing low-power electronics. Go learn about Ohm’s Law!

 It’s a lot of fun, and I hope you enjoy!
 
 P.S. The contest should be up for a while, so don’t worry about being late to the party!

 ## Who else does this stuff?
 
 As far as I know I came up with this stuff independently. I’ve read plenty of time-management resources (which tend to be good) and experimental journaling resources (which tend to be… scarce?).
 
--   [Lion Kimbro][11]: “Make a complete map of every thought you think”. General journaling. [Inteview][12].
--   [Fenn Lipowitz][13] (my roommate): Time log, with an emphasis on being completely machine-readable. Being machine-readable means click for pretty graphs. I took inspiration from how machine-parsable this was recently, but I want to keep my freehand sections too.
--   [Bryan Bishop][14] (acquaintance): meetlog, a system for recording conversations and topics of conversation. Overall I didn’t find this useful because I don’t know hundreds of people. The format is so-so, largely because the author can type very fast, including real-time transcripts. I got the inspiration to write topics of conversation while talking from this. I do something similar if I spend a long time thinking or researching, too.
--   [Bullet Journaling][15]: I dunno, if you’re super lost and don’t know how to write a journal/TODO list, some guy figured it out for you! It’s just the basics that you’d figure out on your own, but it may save time. The site is better than the book. I independently invented most of their notation for TODO lists, I don’t find it too useful for a journal. Other peoples’ bullet journal pages are also useful, not just the original author’s.

+This expands on my previous post about [how to set up an email server](https://blog.za3k.com/installing-email-with-postfix-and-dovecot/ "Installing email with Postfix and Dovecot (with Postgres)").
 
 We’re going to set up a few spam filters in Dovecot under Debian. We’re going to use Sieve, which lets the user set up whichever filters they want. However, we’re going to run a couple pre-baked spam filters regardless of what the user sets up.
 
 1.  Install Sieve.
     
+    ```
     sudo apt-get install dovecot-sieve dovecot-managesieved
+    ```
     
 2.  Add Sieve to Dovecot
     
-    \# /etc/dovecot/dovecot.conf
+    ```
+    # /etc/dovecot/dovecot.conf
     # Sieve and ManageSieve
     protocols = $protocols sieve
     protocol lmtp {
-     mail\_plugins = $mail\_plugins sieve
+     mail_plugins = $mail_plugins sieve
     }
     service managesieve-login {
-     inet\_listener sieve {
+     inet_listener sieve {
      port = 4190
      }
     }
     protocol sieve {
-     managesieve\_logout\_format = bytes ( in=%i : out=%o )
+     managesieve_logout_format = bytes ( in=%i : out=%o )
     }
     plugin {
      # Settings for the Sieve and ManageSieve plugin
      sieve = file:~/sieve;active=~/.dovecot.sieve
-     sieve\_before = /etc/dovecot/sieve.d/
-     sieve\_dir = ~/sieve # For old version of ManageSieve
-     #sieve\_extensions = +vnd.dovecot.filter
-     #sieve\_plugins = sieve\_extprograms
+     sieve_before = /etc/dovecot/sieve.d/
+     sieve_dir = ~/sieve # For old version of ManageSieve
+     #sieve_extensions = +vnd.dovecot.filter
+     #sieve_plugins = sieve_extprograms
     }
+    ```
     
 3.  Install and update SpamAssassin, a heuristic perl script for spam filtering.
     
+    ```
     sudo apt-get install spamasssassin
     sudo sa-update
+    ```
     
-    \# /etc/default/spamassassin
+    ```
+    # /etc/default/spamassassin
     ENABLED=1
     #CRON=1 # Update automatically
+    ```
     
-    \# /etc/spamassassin/local.cf
-    report\_safe 0 # Don't modify headers
+    ```
+    # /etc/spamassassin/local.cf
+    report_safe 0 # Don't modify headers
+    ```
     
+    ```
     sudo service spamassassin start
+    ```
     
 4.  There’s a lot of custom configuration and training you should do to get SpamAssassin to accurately categorize what you consider spam. I’m including a minimal amount here. The following will train SpamAssassin system-wide based on what users sort into spam folders.
     
+    ```
     #!/bin/sh
     # /etc/cron.daily/spamassassin-train
-    all\_folders() {
-            find /var/mail/vmail -type d -regextype posix-extended -regex '.\*/cur|new$'
+    all_folders() {
+            find /var/mail/vmail -type d -regextype posix-extended -regex '.*/cur|new$'
     }
     
-    all\_folders | grep "Spam" | sa-learn --spam -f - >/dev/null 2>/dev/null
-    all\_folders | grep -v "Spam" | sa-learn --ham -f - >/dev/null 2>/dev/null
+    all_folders | grep "Spam" | sa-learn --spam -f - >/dev/null 2>/dev/null
+    all_folders | grep -v "Spam" | sa-learn --ham -f - >/dev/null 2>/dev/null
+    ```
     
 5.  Make Postfix run SpamAssassin as a filter, so that it can add headers as mail comes in.
     
-    \# /etc/postfix/master.cf
+    ```
+    # /etc/postfix/master.cf
     smtp inet n - - - - smtpd
-     -o content\_filter=spamassassin
+     -o content_filter=spamassassin
     # ...
     spamassassin unix - n n - - pipe user=debian-spamd argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient}
+    ```
     
+    ```
     sudo service postfix restart
+    ```
     
 6.  Add SpamAssassin to Sieve. Dovecot (via Sieve) will now move messages with spam headers from SpamAssassin to your spam folder. Make sure you have a “Spam” folder and that it’s set to autosubscribe.
     
-    \# /etc/dovecot/sieve.d/spam-assassin.sieve
-    require \["fileinto"\];
+    ```
+    # /etc/dovecot/sieve.d/spam-assassin.sieve
+    require ["fileinto"];
     # Move spam to spam folder
     if header :contains "X-Spam-Flag" "YES" {
      fileinto "Spam";
      # Stop here - if there are other rules, ignore them for spam messages
      stop;
     }
+    ```
     
+    ```
     cd /etc/dovecot/sieve.d
     sudo sievec spam-assassin.sieve
+    ```
     
 7.  Restart Dovecot
     
+    ```
     sudo service dovecot restart
+    ```

-If you want a really good source of random numbers, you should get a hardware generator. But there’s not a lot of great options out there, and most people looking into this get (understandably) paranoid about backdoors. But, there’s a nice trick: if you combine multiple random sources together with [xor][1], it doesn’t matter if one is backdoored, as long as they aren’t all backdoored. There are some exceptions–if the backdoor is actively looking at the output, it can still break your system. But as long as you’re just generating some random pads, instead of making a kernel entropy pool, you’re fine with this trick.

--   [random-stream][4] (1,000 KB/s), an implementation of the merenne twister pseudo-random-number generator. A worse version of /dev/urandom, use that unless you don’t trust the Linux kernel for some reason.
--   [infnoise][5] (20-23 KB/s), a USB hardware random number generator. Optionally whitens using [keccak][6]. Mine is unfortunately broken (probably?) and outputs “USB read error” after a while

 I think the analysis may be useful to other hackers, as people tend to be insane and cost-insensitive around money. I think having another persons’s finances to look at for comparison is something I’ve wanted for various reasons at various times, and it’s not commonly available. My selfish motivations are to get other people to tell me how I should be saving lots of money, and to feel like my financial decisions are under scrutiny (which is good and bad).

 In this article, I migrate an existing debian 10 buster release, from an unencrypted root drive, to an encrypted root. I used a second hard drive because it’s safer–this is NOT an in-place migration guide. We will be encrypting / (root) only, not /boot. My computer uses UEFI. This guide **is specific to debian**–I happen to know these steps would be different on Arch Linux, for example. They probably work great on a different debian version, and might even work on something debian-based like Ubuntu.

 Apologies if I forget any steps–I wrote this after I did the migration, and not during, so it’s not copy-paste.
 
 Q: Why aren’t we encrypting /boot too?
 
-1.  Encrypting /boot doesn’t add much security. Anyone can guess what’s on my /boot–it’s the same as on everyone debian distro. And encrypting /boot doesn’t prevent tampering–someone can easily replace my encrypted partition by an unencrypted one without my noticing.

 18.  (In my case, I also set up the swap partition after successful boot.) Edit: Oh, also don’t use unencrypted swap with encrypted root. That was dumb.

+The old service, ‘[simple-status](https://github.com/za3k/za3k.com/blob/master/cgi-bin/status-simple)‘ worked as follows:
 
 -   You visited the URL. Then, the status page would (live) kick of about 30 parallel jobs, to check the status of 30 services
 -   The list of services is one-per-file in a the services.d directory.
 -   For each service, it ran a short script, with no command line arguments.
 -   All output is displayed in a simple html table, with the name of the service, the status (with color coding), and a short output line.
 -   The script could return with a success (0) or non-success status code. If it returned success, that status line would display in green for success. If it failed, the line would be highlighted red for failure.
--   Scripts can be anything, but I wrote several utility functions to be called from scripts. For example, “[ping?][5]” checks whether a host is pingable.
--   Each script was wrapped in [timeout][6]. If the script took too long to run, it would be highlighted yellow.

 Mon works as follows
 
 -   The list of 30 services is defined in /etc/mon/con.cf.
 -   For each service, it runs a single-line command (monitor) with arguments. The hostname(s) are added to the command line automatically.
--   All output can be displayed in a simple html table, with the name of the service, the status (with color coding), the time of last and next run, and a short output line. Or, I use ‘[monshow][7]‘, which is similar but in a text format.

 Overall I think that ‘mon’ is much more complex, but only to add features, and it doesn’t have a lot of features I wouldn’t use. It still is pretty simple with a simple interface. I recommend it as both good, and overall better than my system.
 
 My only complaint is that it’s basically impossible to Google, which is why I’m writing a recommendation for it here.

The postal worker really only made a couple funny faces about me being weird, although my friend said she was pretty loud about my walking out with that much cash-equivalent, it went pretty well.

 I’ve written a few simple storytelling games or RPGs lately. They’re all under two pages of rules, and currently they’re all untested (first test is Monday!).
 
--   [Ultimate Archwizards vs the Dark Lord][1] Game for 3-6 players including one GM. Guessing 2-4 hours. Imagine the final episode of a fight anime–everyone is mega-level powered. Relatively goofy. Suitable for beginner players, would work with a beginner GM too. Designed with zero prep in mind.
--   [No, this cannot be! I AM INVINCIBLE!][2] Game for 2-8 players, no GM. More fun with 4+. Guessing 30 minutes. Heroes want to kill Villains, Villains also want to be killed. Villains therefore send wave after slightly harder wave of enemies at the Heroes to level them up. Designed to be comfortable for complete beginners, while letting expert storytellers play in the same group. About half storytelling, half stats. Some gameplay is probably similar to Munchkin, but I haven’t really played Munchkin. There’s a little prep at the start for Villains (5 minutes), almost none for Heroes. The only one of the three that needs playtesting to balance.
--   [Ninjas Ninjas Ninjas!][3] Game for 3 players exactly, no GM. Not for beginners. Guessing 5-30 minutes once you learn the rules (up to you). Frantically fast storytelling, challenges are 30-60 seconds each. There are several roles including the main “narrator”, which players swap often. The main goal is to show how cool your ninja team is, but you do also complete your mission. Can be played with nothing, not even paper. Could be expanded to work with 4 or 5 players, but would need more work.

It looks completely unusable in practice (alignment issues, aside from being Windows-only).
 
 Okay, so I think these are all stupid, because you need some custom software to decode them, which in any case where you’re decoding data stored on paper you probably don’t have that. I want to use standard barcodes, even if they’re going to be lower density. Let’s look at our options. I’m going to skip linear barcodes (low-density) and color barcodes (printing in color is expensive).  Since we need space between symbols, we want to pick the biggest versions of each code we can. For one, whitespace around codes is going to dominate actual code density for layout efficiency, and larger symbols are usually more dense. For another thing, we want to scan as few symbols as possible if we’re doing them one at a time.

-QR codes and PDF417 look like our contenders. PDF417 turns out to not scan well (at all, but especially at large symbol sizes), so despite some nice features let’s pick QR codes. Back when I worked on a [digital library][11] I made a component to generate QR codes on the fly, and I know how to scan them on my phone and webcam already from that, so it would be pretty easy to use them.

 What density can we get on a sheet of A4 paper (8.25 in × 11.00 in, or 7.75in x 10.50in with half-inch margins)? I trust optar’s estimate (600 dpi = 200 pixels per inch) for printed/scanned pages since they seemed to test things. A max-size QR code is 144×144 pixels, or 0.72 x 0.72 inches at maximum density. We can fit 10 x 14 = 140 QR codes with maximum density on the page, less if we want decent spacing. That’s 140 QR codes x (2,953 bytes per QR code) = 413420 bytes = 413K per page before error correction.
 
 That’s totally comparable to the other approaches above, and you can read the results with off-the-shelf software.  Bam.

-    For printing over the network, I used the socket::9100 setting. No idea the command line knobs or dials, just did it through the cups web page.

-    Another reason for me to do this is now my little rasperry pi zero w shows my printer as an AirPrint printer, so now I can print from my iDevices. Brother has their own app for this printer, but I was annoyed having to install a special app for this. My HL2270DW was made without AirPrint.

The used to be a thing (Twibright Optar, IIRC: it’s fallen off the web) that made full-page scannable codes that got an almost useful data density.

An even better version was “Paperback”, but it’s 9 years unmaintained–I’m looking into seeing if there is a maintained Linux port. Both do a lot of things right, even if they have a slightly different goal (high data density, over ease-of-use and foolproof restore).

I tried to do a “poloroid” thing (take a picture of yourself with webcam, immediately print to thermal) and found that mine was shit and the heat overexposed unrelated parts. QR codes seem like a reasonable application, although I’d be concerned about the longevity of thermal paper for backups (can easily fade in heat).

 But we’re programmers, so obviously we’re not going to use a literal checklist. Instead, we’re going to write a little script to auto-start things in a new screen session:
 
+```
 #!/usr/bin/screen -c
-# game\_development.screen.conf
-# Run stand-alone or with screen -c game\_devel.screen.conf
-screen -t "Vim" 2 bash -c "vim -p \*.t"

+screen -t "Vim" 2 bash -c "vim -p *.t"
 bind "r" screen -t "Game" 2 bash run.sh
+```
 
 Or if you prefer tmux:
 
-\# game\_development.tmux.conf
-# Run with tmux -f game\_development.tmux.conf attach
-new-session -s game\_development
-new-window -n "Vim" "bash -c 'vim -p \*.t'"

 Note the main features being used: a shebang line hack for screen, to let this file be self-contained and executable. Opening files in vim in place of a text editor. Binding keys for unit tests, running the program, restarting the server, etc. Now, a similar approach is to add new key bindings to the text editor, but I feel like text editors should edit text, and I like being able to document all the additions with help menus (which screen and tmux both support).

 1.  Generate an SSL/TLS key, which will be used to actually encrypt traffic.
     
+    ```
     DOMAIN=nntp.za3k.com
     openssl genrsa -out ${DOMAIN}.key 4096
     chmod 700 ${DOMAIN}.key
+    ```
     
 2.  Generate a Certificate Signing Request, which is sent to your authentication provider. The details here will have to match the details they have on file (for StartSSL, just the domain name).
     
-    \# -subj "/C=US/ST=/L=/O=/CN=${DOMAIN}" can be omitted to fill in custom identification details
+    ```
+    # -subj "/C=US/ST=/L=/O=/CN=${DOMAIN}" can be omitted to fill in custom identification details
     # -sha512 is the hash of your key used for identification. This was the reasonable option in Oct 2014. It isn't supported by IE6
     openssl req -new -key ${DOMAIN}.key -out ${DOMAIN}.csr -subj "/C=US/ST=/L=/O=/CN=${DOMAIN}" -sha512
+    ```
     
 3.  Submit your Certificate Signing Request to your authentication provider. Assuming the signing request details match whatever they know about you, they’ll return you a certificate. You should also make sure to grab any intermediate and root certificates here.
     
+    ```
     echo "Saved certificate" > ${DOMAIN}.crt
     wget https://www.startssl.com/certs/sca.server1.crt https://www.startssl.com/certs/ca.crt # Intermediate and root certificate for StartSSL
+    ```
     
 4.  Combine the chain of trust (key, CSR, certificate, intermediate certificates(s), root certificate) into a single file with concatenation. Leaving out the key will give you a combined certificate of trust for the key, which you may need for other applications.
     
+    ```
     cat ${DOMAIN}.crt sca.server1.crt >${DOMAIN}.pem # Main cert
     cat ${DOMAIN}.key ${DOMAIN}.crt sca.server1.crt ca.crt >${DOMAIN}.full.pem
     chmod 700 ${DOMAIN}.full.pem
+    ```

 -   The cheapest option is tape media, but tape reader/writers for LTO 6, 7, and 8 are very expensive.
 -   The second-cheapest option is to buy external hard drives, and then open the cases and take out the hard drives. This gives you reliable drives with no warrantee.

 -   Making sure each card gets printed exactly once, in the face of printer failures and updating digital collections. This was hard and took up most of my time, but it’s also insanely boring so I’ll say no more.
 -   Command-line QR code generation, especially without generating intermediate files. I used rqrcode\_png in ruby. I can now hotlink link qr.png?text=Hello%20World and see any text I want, it’s great.

I ended up using the ‘[wkhtmltoimage][6]‘ project, which as far as I can tell, renders the image somewhere internally using [webkit][7] and screenshots it. There’s also a wkhtmltopdf available, which worked well but I couldn’t get to cooperate with index-card sized paper. Nothing else really seems to handle CSS, etc properly and as horrifying as the fundamental approach is, it’s both correct and well-executed.

Scanning cards back into the computer was one of the most pleasant parts of this whole project. It has an intuitive command UI using all the format options I want, and camera feedback to show it’s scanned QR codes (which it does very quickly).

I opted to use a [SHA256 hash][10] (the mysterious numbers at the bottom which form a unique signature generated from the content of the book) and provide a small page on my website which gives you a download based on that. This is what the QR code links to. I was hoping there was some way to provide that without involving me, but I’m unaware of any service available.

 -   That’s 1779 pages total (small ones, these are pocket journals). It’s also 32,000 lines, and 164K words. The text is 1.1MB, the scanned PNG files are 12GB (12000 MB).
 -   In general, it takes me 1 hour to transcribe the last week of notes. Going farther back is harder, partly because my handwriting gets more readable as time progresses (due at least as much to my choice of pen, as my neatness), and partly because I have a harder time guessing at poor handwriting without memory to fill it in, and partly because I didn’t use standard formats back then.
 -   I do have exact numbers I could check, but a lower bound based on this rate is that was overall 90 hours of work. It probably didn’t take more than twice that.

-    Very nice! I often find myself automatically optimizing – the easiest place to see this is in Animal Crossing where I’ll keep a large cash of items for when villagers might ask for one. The idea is to always be prepared (I blame girl scouts). I suppose the negative to this behavior is that it could lead to hording if left unchecked.

 ## Gzip format: Basics and compressing a stream
 
 Let’s take a look at our first example. If you’re on Linux, feel free to run the examples I use as we go.
 
-    echo "hello hello hello hello" | gzip
+```
+echo "hello hello hello hello" | gzip
+```
 
 The bytes gzip outputs are below. You can use *xxd* or any other hex dump tool to view binary files. Notice that the original is 24 bytes, while the compressed version is 29 bytes–gzip is not really intended for data this short, so all of the examples in this article actually get bigger.

 ## DEFLATE format: Basics and fixed huffman coding
 
-DEFLATE is the actual compression format used inside gzip. The format is detailed in [RFC 1951: DEFLATE][11]. DEFLATE is a dense format which uses bits instead of bytes, so we need to take a look at the binary, not the hex, and things will not be byte-aligned. The endian-ness is a little confusing in gzip, so we’ll usually be looking at the “reversed binary” row.

 -   As a hint, whenever we read bits, we use the “reverse” binary order. For Huffman codes, we keep the bit order in reverse. For fixed-length fields like integers, we reverse again into “normal” binary order. I’ll call out the order for each field.

 -   So we’re using “fixed” huffman coding. That means there’s a static, fixed encoding scheme being used, defined by the DEFLATE standard. The scheme is given by the tables below. Note that Length/Distance codes are special–after you read one, you may read some extra bits according to the length/distance lookup tables.

 -   Now we read a series of codes. Each code might be
     -   a literal (one binary byte), which is directly copied to the output
     -   “end of block”. either another block is read, or if this was the last block, DEFLATE stops.
-    -   a length-distance pair. first code is a length, then a distance is read. then some of the output is copied–this reduces the size of repetitive content. the compressor/decompressor can look up to 32KB backwards for duplicate content. This copying scheme is called [LZ77][12].

This copying scheme is called [LZ77](https://en.wikipedia.org/wiki/LZ77_and_LZ78).
 -   Huffman codes are a “prefix-free code” (confusingly also called a “prefix code”). What that means is that, even though the code words are different lengths from one another, you can always unambigously tell which binary *codeword* is next. For example, suppose the bits you’re reading starts with: 0101. Is the next binary codeword 0, 01, 010, or 0101? In a prefix-free code, only one of those is a valid codeword, so it’s easy to tell. You don’t need any special separator to tell you the codeword is over. The space savings from not having a separator is really important for good compression. The “huffman” codes used by DEFLATE are prefix-free codes, but they’re not really optimal Huffman codes–it’s a common misnomer.

-        This is what “Aside: Storing Prefix-Free Codewords as a List of Lengths” is about. The algorithm is given in full in RFC 1952 if you’re interested. Basically, the code words are assigned starting from 0 (or 00, 000, etc) and counting up. As each code is assigned, anything with that code as a prefix becomes unavailable. They are assigned first from shortest to longest, and in the case of ties from leftmost in the list to rightmost in the list.
-        
-        So first we assign 0 to the length-1 codeword (0 is lower than 1), then we assign the length-2 codeword 10 (the lowest length-2 code that doesn’t have a prefix 0), and finally we assign the length-4 codewords from left to right (1100, 1101, 1110, 1111 don’t have a prefix of 0 or 10 — they are the lowest and only codewords without one of those prefixes).

-    Took me a while to understand that I was supposed to be building the tree at this point (although this method compared to what I though of and implemented prior to this is inefficient both in space and speed, also terribly um-intuitive). I’m having trouble understanding exactly how to extract some literals you’ve mentioned:
-    
-    “Byte 18-19: 0000001 10 0110101. Copy “0” code length 11-138 times  
-    0b1010110=86, plus 11 is 97. Literals 0-96 are not present.  
-    Byte 20: 1100 0101: Literal 1. Literal 97 (‘a’) has a codeword of length 1.  
-    Byte 20: 1100 0 101: Literal 2. Number 98 (‘b’) has a codeword of length 2.”  
-      
-      
-    
-    At first I though to get the literals I was supposed to add the code list position to the copy count but then I saw this after:
-    
-    “Byte 20-21: 11000 10 1111111 10. Copy “0” code length 11-138 times. 0b1111111=127, plus 11 is 138. Literals 99-236 are not present.  
-    Byte 21-22: 111111 10 0001000 1. Copy “0” code length 11-138 times. 0b0001000=8, plus 11 is 19. Literals 237-255 are not present”
-    
-    Which doesn’t follow that pattern, how do you determine the literals range?

-        I’m glad this was helpful, but you should really go read RFC 1951 if you’re going to build a decoder. This isn’t meant to be a stand-alone guide.
-        
-        I’m pretty lost trying to follow this comment, sorry. To clarify, for the “dynamic” compression, you first extract the CODING TABLE for the literals (the step you’re talking about). Then, you use the coding table to decompress the actual stream of content. It’s a two-step process, which is why it’s so complex.
-        
-        The key point I suspect you’re missed was: “Let’s read 267 numbers: the lengths of the codeword for each row.” These numbers are the length of the code for each literal in order (all of them, not just some of them). A length of 0 means “not present”.

-            Was gonna say I already had the code table but when it printed it seems the codes got corrupted, I’ll have to get back to you after fixing it. Anyways I find “guides” that don’t use real examples as this one does to be confusing sometimes, usually where it matters, that’s why I was consulting you who provided those key examples, I got a heck of a lot further with your guide than any other I’ve tried following which didn’t give the byte by byte, bit by bit example.

-                    Never min, I think I know where the literals are coming from now, I did this:
-                    
-                    `    printf( "Expecting character '%c', ", c );   printf( "num as a character = '%c'\n", num );    `
-                    
-                    To see if num lined up, since it did I’m guessing those ranges where all the wasted leaves/branches of the huffman tree.

-                You read 267=260+7 codeword-lengths (the numbers 260 and 7 are given by bytes 10-12 in this example).
-                
-                The first 260 codeword-lengths are used for one huffman table: 256 literals (always 256), then 1 “end of block” (always 2), then the remaining 3 are lengths.
-                
-                The next 7 codeword-lengths are used to generate a second huffman table, for distances. The code generation works exactly the same as for the first table.

-                    Even if I use the same method of code generation as before I stiil would need to know where you got those “2”s from in the table immediately following this:
-                    
-                    “We read 7 numbers, that’s the whole distances table. Assign the “standard” binary codewords to generate the following table:”
-                    
-                    Because the previous method used that to determine what symbols to ignore until the code length increases, more specifically I had a “while ( cur\_leng < max\_leng )" loop and a sub loop that went looking for symbols expecting cur\_leng codes and assigning them that way before using those same codes in another sub loop to decide if the next code should be increased further. Without knowing where those code lengths for the distance came from I can't progress.
-                    
-                    Thinking about it now I don't even have the codes for the length symbols, I just have the symbols. If it was supposed to be auto generated then I could understand the codes for the length symbols but I then don't understand the codes for the distance codes as they don't follow the huffman principle of no codes that can be misinterpreted.

-        next\_code\[bits\] = code;  
-        }
-        
-        3) Assign numerical values to all codes, using consecutive  
-        values for all codes of the same length with the base  
-        values determined at step 2. Codes that are never used  
-        (which have a bit length of zero) must not be assigned a  
-        value.

-        for (n = 0; n <= max\_code; n++) {  
-        len = tree\[n\].Len;  
-        if (len != 0) {

-        Distance is how far back you start. Copy is how many symbols you copy.  
-        You just blindly copy characters starting DISTANCE back, but since you’re appending to the string, you never run out of symbols to copy.

 When you click an email address, it automatically opens in your email client. But I don’t have an email client, I use webmail. I wrote a custom handler for Linux.  
   
-First write a program to open [mailto][1] links. Mailto links look like “**mailto:me@mail.com**” or maybe even “**mailto:me@mail.com?subject=mysubject&body=mybody**“. Test it by hand on a few links. Mine ([mailto-opener][2]) composes a new message using my webmail.
+First write a program to open [mailto](https://en.wikipedia.org/wiki/Mailto) links. Mailto links look like “**mailto:me@mail.com**” or maybe even “**mailto:me@mail.com?subject=mysubject&body=mybody**“. Test it by hand on a few links. Mine ([mailto-opener](https://github.com/za3k/short-programs?tab=readme-ov-file#mailto-opener)) composes a new message using my webmail.
 
 Next, write a desktop file for the opener. Here’s one:
 
-    #/usr/local/share/applications/mailto-opener.desktop 
-    [Desktop Entry]
-    Type=Application
-    Name=mailto: link opener (github.com/za3k/short-programs)

+Name=mailto: link opener (github.com/za3k/short-programs)
+
+# The executable of the application, possibly with arguments.
+Exec=/home/zachary/.projects/short-programs/mailto-opener %u
+```
 
 Note the %u in the **Exec=** line. That’s required.
 
 Now update your system mimetype database. On my Arch Linux install, I run
 
-    xdg-mime default mailto-opener.desktop x-scheme-handler/mailto
+```
+xdg-mime default mailto-opener.desktop x-scheme-handler/mailto
+```
 
 Finally, restart your browser. Really. Firefox and Chromium/Chrome both cache mimetype openers.

 It’s served over HTTPS now (not needed for security, but it puts people at ease and enabled Chrome’s autocomplete) and you can order multiple books at a time.
 
 Other than some more visual improvements, the main thing missing is proper detection of page size — my server doesn’t understand about page margins, so it things books are bigger than they really are.

 Sep, Oct, Nov 2014: Vietnam.
 
-A year ago, I left my job at Streak and moved to Vietnam. I felt like I needed change. Vietnam ended up being wonderful; I was really glad I travelled with my friends [Richard][1] and [Kathy][2], which ended up making the experience a hundred times better than it would have been otherwise. The basic environment was: everything is cheap, I newly have endless free time, I was automatically prompted by my friends in the evenings and sometimes during the day to go on small novel adventures involving physical activity, and I had little internet access. This is probably my perfect environment, and I was functioning very well (the vietnamese diet also has small, well-balanced meals which might have helped). For some reason, I was also able to intensely single-task. \[I’d like to write more about what Vietnam is like, but this article is quite long enough as it is\]
+A year ago, I left my job at Streak and moved to Vietnam. I felt like I needed change. Vietnam ended up being wonderful; I was really glad I travelled with my friends [Richard](http://www.jollybit.com/) and [Kathy](http://thedragonseyelashes.tumblr.com/), which ended up making the experience a hundred times better than it would have been otherwise. The basic environment was: everything is cheap, I newly have endless free time, I was automatically prompted by my friends in the evenings and sometimes during the day to go on small novel adventures involving physical activity, and I had little internet access. This is probably my perfect environment, and I was functioning very well (the vietnamese diet also has small, well-balanced meals which might have helped). For some reason, I was also able to intensely single-task. \[I’d like to write more about what Vietnam is like, but this article is quite long enough as it is\]
 
 While I was in Vietnam, I made a to-do list. The to-do list had all the burning projects I actually wanted to do. I’ve ended up accomplishing most of them, at a rate of one every week or two, and it’s a decent summary of what I’ve been doing since. Two things made the to-do list a success. First, it had BIG tasks. These are projects like my recent “set up an IRC server” or “start a publishing company”. Because of that, I don’t get bogged down in minutae, and the tasks are always motivating. I find I function better when I try to carefully plan around having any logistics. The second reason, which I realized today, is that I was very careful to only include tasks I was planning to do (subtly different than tasks I wanted to do). The list was descriptive, not normative, although it certainly included some things like doing taxes I wasn’t wild about.
 
 Looking at my journal and it really only starts up again in March, so I’m going to organize this post in terms of the to-do list. There are a couple items that don’t fit:
 
--   I started dating my wonderful pet, [Lealend][3], while I was in Vietnam. I went to visit them for a month in Puerto Rico where they live. This is very very important to me (the most important thing that happened in the last year), but I don’t usually write about things that personal on my blog so I’m not doing to say much. I’ve been emotionally maturing a lot by being with them.
--   Conventions. I went to [DEF CON][4], which was probably the best single week this year so far. I’m definitely going again next year. I attended a [mirix][5] \[paper\] in the South Bay, which ended up being stressful for transportation-related reasons but really good while I was there. I’m planning on going to [Burning Man][6] this year as well.
--   I started contracting, that’s how I’ve been alive for a year. I’ve been doing some work for [Zinc][7] and [Paul Christiano][8] on a [workflowy clone][9], mostly. I work two hours a day average.
--   I’ve been developing a [minecraft modpack][10] \[I’ll write more about this when it’s stable\], and recently taken an interest in livestreaming.

 There are four pieces in the first iteration.

 A top bottom base, to enclose the keyboard electronics.

 A keyboard plate. The keys fit into the holes here. You type on the top, electronics go in the bottom.

 A top plate. You see the screens, and switches through the cutouts. Otherwise, it keeps the behind-the-scenes wiring out of sight.

 And finally, the top piece.

 Here are the pieces in correct position. In the top will be the screens and battery. The bottom is a keyboard you type on. The whole things is meant to fold on a hinge, much like a laptop.

 The same pieces, spread out.
 
 There were many, many problems with the first design and the first print. I’ll talk about them (and my fixes) in my next post.

 Another update on the zorchpad. We now have a working 16-button keyboard (sadly no QWERTY yet). Here you can see a simple typing program that shows what you type on screen.
