fix 2024/anders swap 2024/straadt
We swapped `2024/anders` and `2024/straadt` by accident.
Sorry (tm Canada 🇨🇦) about that!
We **SINCERELY APOLOGIZE** to both **Anders Kaare Straadt**
and **Sebastian Macke** for the mix up!
We normalized some of the `.gitignore` files for some
of the 2024 winning entries.
Rebuilt 2024 tar files.
Updated `sitemap.xml`.
Ran `make update` to perform the above.

## Judges' remarks:
|

|
|
||||||
When you run the program, after several moments, a `prog.wav` sound file is produced.
|
When we ran this entry the first time (in a virtual machine window), it felt like the VM has rebooted.
|
||||||
|
Then, after the initial feeling had subsided, we were able to appreciate the entry in greater detail.
|
||||||
|
|
||||||
Using a sound player (you may find `sox(1)` is a good choice), you may enjoy the result.
|
Have you ever wondered would what would happen if you recursively removed
|
||||||
|
files starting from the root directory? Are you curious what happens when
|
||||||
|
you launch a [fork bomb](https://en.wikipedia.org/wiki/Fork_bomb)?
|
||||||
|
Within the safety of an virtual walls, can safely give those and other scenarios:
|
||||||
|
just check out the "[Things You Can Do](#todo")" section below.
|
||||||
|
|
||||||
Can you figure out how it produces the various layers of instruments?
|
**NOTE**: For those who do not have a clang compiler environment that
|
||||||
|
supports the `wasm32` target, we provide a `prog.wasm` file.
|
||||||
|
|
||||||
|
**SUGGESTION / REQUEST**: Having a way to build custom boot-up images for this entry would be of interest.

### Obfuscations
|
### Emulator Running Linux
|
||||||
|
|
||||||
- "Helpful" formatting
|
|
||||||
- Character salad
|
|
||||||
- Loop exit trying to hide by a switch statement
|
|
||||||
- Strong string encryption. By that I mean "fmt"=>"gnu".
|
|
||||||
- A `/*{*/` that throws off bracket matching in vim. Begun the editor wars
|
|
||||||
have! (Wait, I'm **on** the vim-team!)
|
|
||||||
- `cm` and `ap` stands for "allpass" and "comb", respectively.
|
|
||||||
- One effect was created with deliberate "memory corruption".
|
|
||||||
|
|
||||||
To encourage tinkering I've obfuscated the song data and program (see Y()) less
|
#### What It Does
|
||||||
than the "library code". Sorry if you wanted to tinker with the library code!
|
|
||||||
|
|
||||||
### Sound quality
|
This is an emulator capable of running a full modern Linux system with a minimal set of features. The system includes:
|
||||||
|
|
||||||
The sample rate of prog.wav is 256kHz because creating aliasing-free waveforms
|
* An OpenRISC 32-Bit CPU
|
||||||
would require more code, but you can always oversample the audio and pass the
|
* A Memory Management Unit
|
||||||
anti-aliasing problem on to the audio player :-) However, the downsampler in my
|
* A UART connected to the Terminal
|
||||||
`mplayer(1)` is poor, but you can use the high-quality resampler in `sox(1)` to create a
|
* An Interrupt Controller
|
||||||
48kHz version:
|
* A Timer Controller
|
||||||
|
|
||||||
``` <!---c--->
|
|
||||||
sox prog.wav -r 48000 prog.48kHz.wav
|
<div id="todo">
|
||||||
|
### Things You Can Do
|
||||||
|
</div>
|
||||||
|
|
||||||
|
|
||||||
|
#### Look Up Specs
|
||||||
|
|
||||||
|
First, you can look up the specs of the emulated system. The following commands will give you a good overview:
|
||||||
|
|
||||||
|
``` <!---sh-->
|
||||||
|
uname -a
|
||||||
|
free -h
|
||||||
|
cat /proc/cpuinfo
|
||||||
|
cat /proc/meminfo
|
||||||
|
cat /proc/interrupts
|
||||||
|
cat /proc/timer_list
|
||||||
```
|
```
|
||||||
|
|
||||||
### Tricks (the condescending part)
|
|
||||||
|
|
||||||
- Kick drum from sines, pitched up to create toms.
|
#### Fork Bomb Visualized
|
||||||
- Roland TR-808 style hi-hats (a bunch of high-pass filtered square waves).
|
|
||||||
- SID/C64-style snare drum (oscillates between noise and square wave).
|
|
||||||
- There's some FM synthesis in the bass.
|
|
||||||
- Schroeder reverberator a la Freeverb. The same building blocks are used for
|
|
||||||
the echo effect.
|
|
||||||
- Waveshaping/overdrive using tanh(x), ohh yeaaah..
|
|
||||||
|
|
||||||
I used this Python snippet to generate `q0[2]` and `q0[3]`:
|
For educational purposes, type the following two lines and watch the process tree grow:
|
||||||
|
|
||||||
``` <!---python-->
|
``` <!---sh-->
|
||||||
def X(s): print(hex(int(s.replace("x","1").replace(".","0")[::-1],2))) # not for iopcc-use
|
b(){ sleep 2; b|b; }
|
||||||
X(".x.x..xx.x.xx.xxx.xx.xxx..xx.xxx")
|
(b &) && watch -n1 pstree -p
|
||||||
X("x.xx.x.x.x.xxxxxx.xx.xxx.xxxxxxx")
|
|
||||||
```
|
```
|
||||||
|
|
||||||
|
Or just run:
|
||||||
|
|
||||||
|
``` <!---sh-->
|
||||||
|
./fork_bomb.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
Note: You won't be able to stop the emulator anymore and will need to kill the process.
|
||||||
|
|
||||||
|
|
||||||
|
#### Delete Filesystem
|
||||||
|
|
||||||
|
Ever wanted to know what happens when you delete your computer's filesystem?
|
||||||
|
Now is your chance to find out!
|
||||||
|
|
||||||
|
``` <!---sh-->
|
||||||
|
rm -rf /
|
||||||
|
```
|
||||||
|
|
||||||
|
Even after removal, your system will still be in a well-defined state.
|
||||||
|
For example, you can still run commands such as:
|
||||||
|
|
||||||
|
``` <!---sh-->
|
||||||
|
cd /proc
|
||||||
|
echo *
|
||||||
|
```
|
||||||
|
|
||||||
|
Be careful: You won't be able to stop the emulation anymore and will need to kill the process.
|
||||||
|
|
||||||
|
|
||||||
|
#### Run C64 Emulation
|
||||||
|
|
||||||
|
A full-fledged C64 emulator is included. Run it via:
|
||||||
|
|
||||||
|
``` <!---sh-->
|
||||||
|
./c64
|
||||||
|
```
|
||||||
|
|
||||||
|
Since the C64 is little-endian and runs on a big-endian machine, which itself runs on a little-endian machine, it combines the best of both worlds into a cool intermediate format. Might this be the future of endianness? 🤔
|
||||||
|
|
||||||
|
|
||||||
|
#### Run Itself
|
||||||
|
|
||||||
|
With `./prog`, you can run the emulator within itself. This is a bit meta, but it works.
|
||||||
|
The emulator would be able to run Linux as well, but it is tweaked to run with less memory and on a big-endian machine.
|
||||||
|
|
||||||
|
|
||||||
|
#### Full scripting capabilities
|
||||||
|
|
||||||
|
With `vi`, you got an awesome editor and can write scripts in *ash* such as.
|
||||||
|
|
||||||
|
``` <!---sh-->
|
||||||
|
i=1
|
||||||
|
while [ "$i" -le 10 ]
|
||||||
|
do
|
||||||
|
echo "Hello World"
|
||||||
|
i=$(expr "$i" + 1)
|
||||||
|
done
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
#### Run in the Web Browser
|
||||||
|
|
||||||
|
Did you know that you can run this emulator in a web browser?
|
||||||
|
|
||||||
|
First, compile with Clang on systems that support a target of `wasm32`:
|
||||||
|
|
||||||
|
``` <!---sh-->
|
||||||
|
make prog.wasm
|
||||||
|
```
|
||||||
|
|
||||||
|
Then, for example, run a local web server with the following command:
|
||||||
|
|
||||||
|
``` <!---sh-->
|
||||||
|
python3 -m http.server 8000
|
||||||
|
```
|
||||||
|
|
||||||
|
Open your browser and go to `http://localhost:8000/prog.html`. You can now run the emulator in the browser.
|
||||||
|
|
||||||
|
|
||||||
|
### Obsfucation
|
||||||
|
|
||||||
|
The obfuscation is mainly a result of compression, plus a healthy dose of recursion and the usual endian mischief.
|
||||||
|
For some reason, LLMs might think that this is a Smoothed Particle Hydrodynamics (SPH) simulation.
|
||||||
|
|
||||||
|
Sigh, so much space left. More than enough for multi-core support, a full-fledged windowing system, or networking.
|
||||||
|
Well, there's always next year.

<p>When you run the program, after several moments, a <code>prog.wav</code> sound file is produced.</p>
|
<p>When we ran this entry the first time (in a virtual machine window), it felt like the VM has rebooted.
|
||||||
<p>Using a sound player (you may find <code>sox(1)</code> is a good choice), you may enjoy the result.</p>
|
Then, after the initial feeling had subsided, we were able to appreciate the entry in greater detail.</p>
|
||||||
<p>Can you figure out how it produces the various layers of instruments?</p>
|
<p>Have you ever wondered would what would happen if you recursively removed
|
||||||
|
files starting from the root directory? Are you curious what happens when
|
||||||
|
you launch a <a href="https://en.wikipedia.org/wiki/Fork_bomb">fork bomb</a>?
|
||||||
|
Within the safety of an virtual walls, can safely give those and other scenarios:
|
||||||
|
just check out the “<a href="#things-you-can-do">Things You Can Do</a>(#todo”)” section below.</p>
|
||||||
|
<p><strong>NOTE</strong>: For those who do not have a clang compiler environment that

||||||
|
supports the <code>wasm32</code> target, we provide a <code>prog.wasm</code> file.</p>

<h3 id="emulator-running-linux">Emulator Running Linux</h3>
|
||||||
|
<h4 id="what-it-does">What It Does</h4>
|
||||||
|
<p>This is an emulator capable of running a full modern Linux system with a minimal set of features. The system includes:</p>
|
||||||
<ul>
|
<ul>
|
||||||
<li>“Helpful” formatting</li>
|
<li>An OpenRISC 32-Bit CPU</li>
|
||||||
<li>Character salad</li>
|
<li>A Memory Management Unit</li>
|
||||||
<li>Loop exit trying to hide by a switch statement</li>
|
<li>A UART connected to the Terminal</li>
|
||||||
<li>Strong string encryption. By that I mean “fmt”=>“gnu”.</li>
|
<li>An Interrupt Controller</li>
|
||||||
<li>A <code>/*{*/</code> that throws off bracket matching in vim. Begun the editor wars
|
<li>A Timer Controller</li>
|
||||||
have! (Wait, I’m <strong>on</strong> the vim-team!)</li>
|
|
||||||
<li><code>cm</code> and <code>ap</code> stands for “allpass” and “comb”, respectively.</li>
|
|
||||||
<li>One effect was created with deliberate “memory corruption”.</li>
|
|
||||||
</ul>
|
</ul>
|
||||||
<p>To encourage tinkering I’ve obfuscated the song data and program (see Y()) less
|
<div id="todo">
|
||||||
than the “library code”. Sorry if you wanted to tinker with the library code!</p>

<p>The sample rate of prog.wav is 256kHz because creating aliasing-free waveforms
|
<h4 id="look-up-specs">Look Up Specs</h4>
|
||||||
would require more code, but you can always oversample the audio and pass the
|
<p>First, you can look up the specs of the emulated system. The following commands will give you a good overview:</p>
|
||||||
anti-aliasing problem on to the audio player :-) However, the downsampler in my
|
<pre><code> uname -a
|
||||||
<code>mplayer(1)</code> is poor, but you can use the high-quality resampler in <code>sox(1)</code> to create a
|
free -h
|
||||||
48kHz version:</p>
|
cat /proc/cpuinfo
|
||||||
<pre class="<!---c--->"><code> sox prog.wav -r 48000 prog.48kHz.wav</code></pre>
|
cat /proc/meminfo
|
||||||
<h3 id="tricks-the-condescending-part">Tricks (the condescending part)</h3>
|
cat /proc/interrupts
|
||||||
<ul>
|
cat /proc/timer_list</code></pre>
|
||||||
<li>Kick drum from sines, pitched up to create toms.</li>
|
<h4 id="fork-bomb-visualized">Fork Bomb Visualized</h4>
|
||||||
<li>Roland TR-808 style hi-hats (a bunch of high-pass filtered square waves).</li>
|
<p>For educational purposes, type the following two lines and watch the process tree grow:</p>
|
||||||
<li>SID/C64-style snare drum (oscillates between noise and square wave).</li>
|
<pre><code> b(){ sleep 2; b|b; }
|
||||||
<li>There’s some FM synthesis in the bass.</li>
|
(b &) && watch -n1 pstree -p</code></pre>
|
||||||
<li>Schroeder reverberator a la Freeverb. The same building blocks are used for
|
<p>Or just run:</p>
|
||||||
the echo effect.</li>
|
<pre><code> ./fork_bomb.sh</code></pre>
|
||||||
<li>Waveshaping/overdrive using tanh(x), ohh yeaaah..</li>
|
<p>Note: You won’t be able to stop the emulator anymore and will need to kill the process.</p>
|
||||||
</ul>
|
<h4 id="delete-filesystem">Delete Filesystem</h4>
|
||||||
<p>I used this Python snippet to generate <code>q0[2]</code> and <code>q0[3]</code>:</p>
|
<p>Ever wanted to know what happens when you delete your computer’s filesystem?
|
||||||
<pre><code> def X(s): print(hex(int(s.replace("x","1").replace(".","0")[::-1],2))) # not for iopcc-use
|
Now is your chance to find out!</p>
|
||||||
X(".x.x..xx.x.xx.xxx.xx.xxx..xx.xxx")
|
<pre><code> rm -rf /</code></pre>
|
||||||
X("x.xx.x.x.x.xxxxxx.xx.xxx.xxxxxxx")</code></pre>
|
<p>Even after removal, your system will still be in a well-defined state.
|
||||||
|
For example, you can still run commands such as:</p>
|
||||||
|
<pre><code> cd /proc
|
||||||
|
echo *</code></pre>
|
||||||
|
<p>Be careful: You won’t be able to stop the emulation anymore and will need to kill the process.</p>
|
||||||
|
<h4 id="run-c64-emulation">Run C64 Emulation</h4>
|
||||||
|
<p>A full-fledged C64 emulator is included. Run it via:</p>
|
||||||
|
<pre><code> ./c64</code></pre>
|
||||||
|
<p>Since the C64 is little-endian and runs on a big-endian machine, which itself runs on a little-endian machine, it combines the best of both worlds into a cool intermediate format. Might this be the future of endianness? 🤔</p>
|
||||||
|
<h4 id="run-itself">Run Itself</h4>
|
||||||
|
<p>With <code>./prog</code>, you can run the emulator within itself. This is a bit meta, but it works.
|
||||||
|
The emulator would be able to run Linux as well, but it is tweaked to run with less memory and on a big-endian machine.</p>
|
||||||
|
<h4 id="full-scripting-capabilities">Full scripting capabilities</h4>
|
||||||
|
<p>With <code>vi</code>, you got an awesome editor and can write scripts in <em>ash</em> such as.</p>
|
||||||
|
<pre><code> i=1
|
||||||
|
while [ "$i" -le 10 ]
|
||||||
|
do
|
||||||
|
echo "Hello World"
|
||||||
|
i=$(expr "$i" + 1)
|
||||||
|
done</code></pre>
|
||||||
|
<h4 id="run-in-the-web-browser">Run in the Web Browser</h4>
|
||||||
|
<p>Did you know that you can run this emulator in a web browser?</p>
|
||||||
|
<p>First, compile with Clang on systems that support a target of <code>wasm32</code>:</p>
|
||||||
|
<pre><code> make prog.wasm</code></pre>
|
||||||
|
<p>Then, for example, run a local web server with the following command:</p>
|
||||||
|
<pre><code> python3 -m http.server 8000</code></pre>
|
||||||
|
<p>Open your browser and go to <code>http://localhost:8000/prog.html</code>. You can now run the emulator in the browser.</p>
|
||||||
|
<h3 id="obsfucation">Obsfucation</h3>
|
||||||
|
<p>The obfuscation is mainly a result of compression, plus a healthy dose of recursion and the usual endian mischief.
|
||||||
|
For some reason, LLMs might think that this is a Smoothed Particle Hydrodynamics (SPH) simulation.</p>
|
||||||
|
<p>Sigh, so much space left. More than enough for multi-core support, a full-fledged windowing system, or networking.
|
||||||
|
Well, there’s always next year.</p>

## Judges' remarks:

When we ran this entry the first time (in a virtual machine window), it felt like the VM has rebooted.
|
When you run the program, after several moments, a `prog.wav` sound file is produced.
|
||||||
Then, after the initial feeling had subsided, we were able to appreciate the entry in greater detail.
|
|
||||||
|
|
||||||
Have you ever wondered would what would happen if you recursively removed
|
Using a sound player (you may find `sox(1)` is a good choice), you may enjoy the result.

files starting from the root directory? Are you curious what happens when

|

you launch a [fork bomb](https://en.wikipedia.org/wiki/Fork_bomb)?

Within the safety of an virtual walls, can safely give those and other scenarios:

just check out the "[Things You Can Do](#todo")" section below.

**NOTE**: For those who do not have a clang compiler environment that

**SUGGESTION / REQUEST**: Having a way to build custom boot-up images for this entry would be of interest.

### Emulator Running Linux

### Obfuscations
|
||||||
|
|
||||||
|
- "Helpful" formatting
|
||||||
|
- Character salad
|
||||||
|
- Loop exit trying to hide by a switch statement
|
||||||
|
- Strong string encryption. By that I mean "fmt"=>"gnu".
|
||||||
|
- A `/*{*/` that throws off bracket matching in vim. Begun the editor wars
|
||||||
|
have! (Wait, I'm **on** the vim-team!)
|
||||||
|
- `cm` and `ap` stands for "allpass" and "comb", respectively.
|
||||||
|
- One effect was created with deliberate "memory corruption".
|
||||||
|
|
||||||
#### What It Does

To encourage tinkering I've obfuscated the song data and program (see Y()) less

than the "library code". Sorry if you wanted to tinker with the library code!
|
||||||
|
|
||||||
This is an emulator capable of running a full modern Linux system with a minimal set of features. The system includes:
|
### Sound quality
|
||||||
|
|
||||||
* An OpenRISC 32-Bit CPU
|
The sample rate of prog.wav is 256kHz because creating aliasing-free waveforms
|
||||||
* A Memory Management Unit
|
would require more code, but you can always oversample the audio and pass the
|
||||||
* A UART connected to the Terminal
|
anti-aliasing problem on to the audio player :-) However, the downsampler in my
|
||||||
* An Interrupt Controller
|
`mplayer(1)` is poor, but you can use the high-quality resampler in `sox(1)` to create a
|
||||||
* A Timer Controller
|
48kHz version:
|
||||||
|
|
||||||
|
``` <!---c--->
|
||||||
<div id="todo">
|
sox prog.wav -r 48000 prog.48kHz.wav
|
||||||
### Things You Can Do
|
|
||||||
</div>
|
|
||||||
|
|
||||||
|
|
||||||
#### Look Up Specs
|
|
||||||
|
|
||||||
First, you can look up the specs of the emulated system. The following commands will give you a good overview:
|
|
||||||
|
|
||||||
``` <!---sh-->
|
|
||||||
uname -a
|
|
||||||
free -h
|
|
||||||
cat /proc/cpuinfo
|
|
||||||
cat /proc/meminfo
|
|
||||||
cat /proc/interrupts
|
|
||||||
cat /proc/timer_list
|
|
||||||
```
|
```
|
||||||
|
|
||||||
|
### Tricks (the condescending part)
|
||||||
|
|
||||||
#### Fork Bomb Visualized
|
- Kick drum from sines, pitched up to create toms.
|
||||||
|
- Roland TR-808 style hi-hats (a bunch of high-pass filtered square waves).
|
||||||
|
- SID/C64-style snare drum (oscillates between noise and square wave).
|
||||||
|
- There's some FM synthesis in the bass.
|
||||||
|
- Schroeder reverberator a la Freeverb. The same building blocks are used for
|
||||||
|
the echo effect.
|
||||||
|
- Waveshaping/overdrive using tanh(x), ohh yeaaah..
|
||||||
|
|
||||||
For educational purposes, type the following two lines and watch the process tree grow:
|
I used this Python snippet to generate `q0[2]` and `q0[3]`:
|
||||||
|
|
||||||
``` <!---sh-->
|
``` <!---python-->
|
||||||
b(){ sleep 2; b|b; }
|
def X(s): print(hex(int(s.replace("x","1").replace(".","0")[::-1],2))) # not for iopcc-use
|
||||||
(b &) && watch -n1 pstree -p
|
X(".x.x..xx.x.xx.xxx.xx.xxx..xx.xxx")
|
||||||
|
X("x.xx.x.x.x.xxxxxx.xx.xxx.xxxxxxx")
|
||||||
```
|
```
|
||||||
|
|
||||||
Or just run:
|
|
||||||
|
|
||||||
``` <!---sh-->
|
|
||||||
./fork_bomb.sh
|
|
||||||
```
|
|
||||||
|
|
||||||
Note: You won't be able to stop the emulator anymore and will need to kill the process.
|
|
||||||
|
|
||||||
|
|
||||||
#### Delete Filesystem
|
|
||||||
|
|
||||||
Ever wanted to know what happens when you delete your computer's filesystem?
|
|
||||||
Now is your chance to find out!
|
|
||||||
|
|
||||||
``` <!---sh-->
|
|
||||||
rm -rf /
|
|
||||||
```
|
|
||||||
|
|
||||||
Even after removal, your system will still be in a well-defined state.
|
|
||||||
For example, you can still run commands such as:
|
|
||||||
|
|
||||||
``` <!---sh-->
|
|
||||||
cd /proc
|
|
||||||
echo *
|
|
||||||
```
|
|
||||||
|
|
||||||
Be careful: You won't be able to stop the emulation anymore and will need to kill the process.
|
|
||||||
|
|
||||||
|
|
||||||
#### Run C64 Emulation
|
|
||||||
|
|
||||||
A full-fledged C64 emulator is included. Run it via:
|
|
||||||
|
|
||||||
``` <!---sh-->
|
|
||||||
./c64
|
|
||||||
```
|
|
||||||
|
|
||||||
Since the C64 is little-endian and runs on a big-endian machine, which itself runs on a little-endian machine, it combines the best of both worlds into a cool intermediate format. Might this be the future of endianness? 🤔
|
|
||||||
|
|
||||||
|
|
||||||
#### Run Itself
|
|
||||||
|
|
||||||
With `./prog`, you can run the emulator within itself. This is a bit meta, but it works.
|
|
||||||
The emulator would be able to run Linux as well, but it is tweaked to run with less memory and on a big-endian machine.
|
|
||||||
|
|
||||||
|
|
||||||
#### Full scripting capabilities
|
|
||||||
|
|
||||||
With `vi`, you got an awesome editor and can write scripts in *ash* such as.
|
|
||||||
|
|
||||||
``` <!---sh-->
|
|
||||||
i=1
|
|
||||||
while [ "$i" -le 10 ]
|
|
||||||
do
|
|
||||||
echo "Hello World"
|
|
||||||
i=$(expr "$i" + 1)
|
|
||||||
done
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
#### Run in the Web Browser
|
|
||||||
|
|
||||||
Did you know that you can run this emulator in a web browser?
|
|
||||||
|
|
||||||
First, compile with Clang on systems that support a target of `wasm32`:
|
|
||||||
|
|
||||||
``` <!---sh-->
|
|
||||||
make prog.wasm
|
|
||||||
```
|
|
||||||
|
|
||||||
Then, for example, run a local web server with the following command:
|
|
||||||
|
|
||||||
``` <!---sh-->
|
|
||||||
python3 -m http.server 8000
|
|
||||||
```
|
|
||||||
|
|
||||||
Open your browser and go to `http://localhost:8000/prog.html`. You can now run the emulator in the browser.
|
|
||||||
|
|
||||||
|
|
||||||
### Obsfucation
|
|
||||||
|
|
||||||
The obfuscation is mainly a result of compression, plus a healthy dose of recursion and the usual endian mischief.
|
|
||||||
For some reason, LLMs might think that this is a Smoothed Particle Hydrodynamics (SPH) simulation.
|
|
||||||
|
|
||||||
Sigh, so much space left. More than enough for multi-core support, a full-fledged windowing system, or networking.
|
|
||||||
Well, there's always next year.
