But seriously, "The Surge" or any other details of the US invasion of Iraq don't really matter.
The fact that fewer Americans died in 9/11 than have been sent to death by our president since doesn't matter.
The fact that Iraq had nothing to do with 9/11 in the first place doesn't matter.
The US has already built many permanent military bases in Iraq, and will maintain a sizable presence there for the forseeable future.
Why? Because the thousands of American lives and hundreds of billions spent on our little war is an investment
in the world's second-largest oil reserves and will be paid back to the wealthiest Americans ten-fold by
American corporations that exploit it in the years to come.
So you see, it's all quite logical.

Now that electronics are so cheap and widespread it's time to make them less toxic and more recycle-friendly.
- The Periodic Table Table — this guy built a conference table in the shape of the periodic table and then proceeded to gather sample of each element for display in the table. the site is chock-full of interesting photographs, information and stories; one could spend days just exploring this site (and planning their own table).

 Uncle Tungsten after perusing the element links of the Periodic Table Table; it is the story of Oliver Sacks' childhood in Britain around the time of WWII, his fascination with chemistry, experimentation and science in general (which is why I got the book) but also of being Jewish, being part of a large family, being introverted and just growing up.

- Biometric identification seems to be all the rage these days; for example one institution of which I know has installed a TSI Handpunch TSI H 103 which clocks you in and out of work via your bare hand instead of a punchcard. One interesting unintended consequence? It is the one place that everyone in the whole office must press and hold their bare hand twice each day. Given that your hands are the least sanitary part of your body (things our hands touch like dishrags, office phones and keyboards contain far more germs than a toilet seat) I would posit that hand scanners are a wonderful, high-tech way to spread germs.
Now, I'm no hysterical germophobe, but I'd rather accept a piece of used chewing gum from a stranger than slide my hand onto an uncleaned plastic slab containing the daily grease and germs of an office full of people, especially during flu season.
I would suggest first and foremost that if you're considering one of these machines for whatever reason you not install it due to its privacy implications; but if you do
install one please provide an adjacent sink and/or hand sanitizer; if your institution already has one, speak up and say something — you sure as hell would if your office had a single toilet with no tissue or sink, and this is worse.

- Is Attacking Iran a Viable Option? — No, it's not. Besides, the reason Iran would want nuclear weapons is because the country listed right before it in Bush's "Axis of Evil" was invaded. If the USA would stop its extremist foreign policies then perhaps its potential opponents might have less of a reason to resort to extremes. My neighbor doesn't own a gun, and I don't particularly want him to; but if I threaten to kill him and then add his name to a "People To Kill" list then he may go and buy one.
But none of this particularly matters because those who control USA foreign policy aren't particularly interested in world peace or stability.

- I am pleased to announce a new project of mine named LANassert, a poorly-named, well-intentioned project with the aim of making sense of one's local network. Feel free to download the source from my subversion repository:
svn co svn://parseerror.dyndns.org/LANassert/
LANassert is a userspace command-line program targeted at network admins and nosy programmers.
The user writes a series of rules (assertions) describing what healthy, good traffic on their network is supposed to look like
(i.e. "All DNS traffic should go to/from Official DNS Server 1 or 2").
LANassert applies these assertions to network traffic in real-time and notifies the user when one of them doesn't match.
Using this feedback, the user can investigate the cause of this traffic — correcting misconfigured boxes, investigating suspicious traffic,
and augmenting the ruleset.
After a few rounds of feedback the user ends up with a set of rules that accurately depicts what their network really looks like,
which is a valuable resource.
Unlike an idealized, static network diagram the ruleset will show you all the warts of your actual network and can be actively tested.

2006-09-07 I'm trying to put together a Wi-Fi triangulation app for Windows that would allow the location of APs and of client machines, assuming the position of a few APs is known and a few machines on the (W)LAN run it. Unfortunately, the API and documentation from Microsoft are horrendous (par for the course from them). This app would be much easier to write for Linux, but unfortunately that's not an option this time.
- 2006-09-05 Using sysinternals' excellent ProcessExplorer tool I noticed a pair of processes that I couldn't explain, and when killed exhibited the classic Robin Hood and Friar Tuck behavior, each re-launching the other. I managed to get the virus off the machine, but it made me realize how poor the built-in tools for Windows really are. If I did not already know about and have ProcessExplorer and an anti-virus I would have had a much harder time even discovering the problem, let alone fixing it. What I really wanted once I discovered the rogue processes was the ability to trap them (i.e. throw them in their own jail-like area where they would be isolated from the rest of them system), freeze them (i.e. stop them mid-run and examine them), monitor their activity as well as take complete control over them, (i.e. turn off the ability for them to perform certain syscalls). I will have to investigate if tools like this already exist, and if not...

So I spent all yesternight trying to maximize bandwidth utilization on a side project of mine (
svn co svn://parseerror.dyndns.org/web/),
and on the drive to work this morning on I-95 I noticed that the to-NYC side was completely
clogged while the away-from-NYC side was pretty sparse and I thought that was pretty bad bandwidth utilization. I imagined a divider system that was mobile
and could be adjusted from one side or the other, stealing a lane or two from the space-rich side and giving it to the space-poor. But then I
considered the drawbacks, and there are lots of them (potentially), and I sort of left it at that.
Well, it turns out that such systems are already being planned for some of the USA's most crowded highways

This Is Not A Place of Honor
- How Will Future Generations Be Warned? Steps planned to warn future generations of the radioactive material buried by The Waste Isolation Pilot Plant. They plan to use many large, obvious markers and warnings in many languages in order to ensure no one disturbs the site over the next 10,000 years. The more I think about it the more I disagree with this plan. Here's why:
Link to #10,000_years
How Does One Keep Something Safe for 10,000 Years?
I would posit that the best guide for the next 10,000 years is the last 10,000. While the future will certainly not mirror the past in detail, the same broad issues will indeed manifest themselves over the future millennia as have in the past. Indeed, it would be naive to think that time will treat us any differently than those who came before us.
What Do We Know About the Past?
Everyone knows about Stonehenge, the pyramids of Giza, the Incan city of Machu Picchu and maybe even the Mayan's Chichen Itza. But that's the point — if large sites are erected they are discovered, plundered, destroyed, explored and then "restored" (usually in this order). "Hidden in plain sight" doesn't quite work at these scales.
Why do humans build giant structures, anyways? Almost certainly selfish reasons, whether explicit at the time of construction or not. Whether built to facilitate rituals, honor kings, or provide housing, in the end they serve the same purpose. Documentation and and (hopefully) preservation of a piece of the culture that built it. Mankind is acutely aware of its own mortality, and even if in 50 years a king will no longer exist, in 5,000 his memorial may still. Large structures are never built in plain sight for things that are intended to be hidden.
Every single ancient site that has ever been found has been explored. Why? Some of these sites are these civilization's most sacred places: homes to rituals, tombs of their kings. We would be offended if a team of researchers showed up in our churches or dug up our grandparents' graves; what right have we? Humans are curious. Our manners are excercised inversely proportional to our detachment from the subject. In the distant future, our ancestors will feel about us and our remains as we do about the Iceman on the cover of National Geographic (he's about half as old as our site must last).
Language and Warnings
We have no idea if any spoken languages even existed 10,000 years ago, and we haven't been able to find any written ones half that old. We can safely assume that at best, our current languages which we love dearly, will not survive as they are. How will future generations read our warnings? If it wasn't for the Rosetta Stone, how would we be reading Egyptian hieroglyphs today? The pictures on the walls of pyramids could have read "WARNING: IMMINENT DEATH" (and some of them probably did), but that didn't do a very good job at keeping grave robbers nor scientists from unearthing entire sites in a quest for riches and knowledge. All ancient sites that have ever been discovered have been excavated.
Stonehenge
We don't even know exactly when Stonehenge was built, but it is at least less than half as old as our site must last. It is known that Stonehenge has some astronomical significance, though scientists have been aruging for years about even this. While we know some very rudimentary facts, we understand very little about the people who built it or their purposes for doing so.
If Stonehenge contained radioactive waste from an advanced culture from 5,000 years past, we wouldn't have even known it until 1928 when Geiger and Müller upgraded Geiger's original primitive radiation detector.
What Is Certain About the Future
Bad Times
If the past has taught us anything, it has taught us that the the coming millenia will bring good times and bad. There will be wars, famine, climate change. Families will come to power, rule, and die off. Countries will be born and die. The oceans and deserts of the world will rise, fall and shift as does the global thermometer. Once great cities will dwindle and die as new ones are built. While we don't know where or when these things will happen, we must accept that they will. A site cannot be guarded over such a long period of time.
Conclusions
- Every site that has ever been discovered has been explored.
- No warning has ever kept a site from being excavated.
- Therefore, in order to keep the site from being excavated it must never be found.
The logical conclusion is NOT to model a repository of radioactive waste after the known ancient sites that have withstood the test of time. The vast majority of these sites have been plundered long before modern discovery, and many of the oldest sites are very poorly understood at even the most fundamental levels.
Instead, hide it away. No berms, no pyramids, no temples. No warnings or markers. Fill it up, fill it in and cover it up. I urge the WIPP to resist the temptation of building a temple to the Gods of fission.

supported in which versions. Compare for yourself:

For me B is far more informative, at a glance, than A. The "icon vs. nothing" approach is instantly recognizable, while in the "yes vs. no" approach the words aren't different enough, and my brain needs to interpret each one individually. It is also harder to figure out the pattern which is immediately obvious in B.
After looking at some other examples, I found that adding color was an effective way of meeting in the middle... colorizing the text or background gives you the ability to add more information than just a yes/no...

...There is the problem, albeit a relatively minor one, of relying on CSS support (not all browsers have it, or have it properly implemented) to make your grid more readable. And while I think D actually looks kind of nice, there is something psychologically unsatisfying about having No listed along with your product; I think B's focus is more positive... perhaps we could meet in the middle...

I don't think the hardware is to blame, probably the drivers, or Windows; but I can't exact revenge on either of those in a satisfying, physical way. After days of frustration with the NETGEAR I put in a Symbol card, which works fine. $60 down the drain.

- So spox in #php has a bot, mod_spox, that has all these nifty features, one of them being the ability to translate between languages. Initially it was just a one-off thing
where you'd say
@translate en|es Hello! and get <mod_spox> Hola! which is neat but not really useful. Then, we had someone who only spoke Spanish
enter the room and ask for help. My Spanish is very rudimentary and I couldn't really help him; then I suggested that a feature be added to mod_spox to "attach" translate
to a person, so if they only spoke Spanish it would translate whatever they said to the channel from Spanish->English and vice versa. So spox added this feature and today someone
speaking only French came in:
< spox> @translate-add fr {-Neo-}
<mod_spox> {-neo-} is now being tracking for translation.
...
<{-Neo-}> elle ne veu pas s'executer et il y a une fatal erreur
<mod_spox> Translation ({-neo-}): it veu not executer and there is fatal an error
<spox> {-Neo-}: what is the error?
<mod_spox> {-neo-}: quelle est l'erreur ?
<{-Neo-}> "Fatal error: Call to undefined function: imagecreatefromjpeg() in /www/.. line 19"
<mod_spox> Translation ({-neo-}): "Fatal error: Call to undefined function: imagecreatefromjpeg() in /www/.. line 19"
<HaNtU]uU[> probably not compiled with it.
<spox> {-Neo-}: you need to compile PHP with GD support
<mod_spox> {-neo-}: vous devez compiler PHP avec l'appui de GD
...
<{-Neo-}> merci mod_spox
<mod_spox> Translation ({-neo-}): thank you mod_spox
<spox> lol
<chalupah> I thought that was pretty awesome, myself
<spox> i know
<{-Neo-}> spox je ne parle pas anglais
<mod_spox> Translation ({-neo-}): spox I do not speak English
<{-Neo-}> je ne parle que francais
<mod_spox> Translation ({-neo-}): I only speak French
<spox> {-Neo-}: yes, i know
<spox> @translate-remove {-Neo-}
<mod_spox> {-neo-} is no longer being tracked for translation.
So, it makes the conversation a little harder to follow, floods the chan a bit, and produces poor English and probably worse French, and mod_spox gets
thanked instead of spox, but in the end it at least provided an opportunity to communicate and hopefully got {-Neo-} on his way; whereas previously
we would not have been able to help him at all.

* 0xE0 | 1 | 2 | 3 |

* +---+---+---+
* 0x70 | * | 0 | # |
* +---+---+---+
*
* we write the row we want to read into the high
* 4 bits and then read the low 3 bits, which
* contain a 0 in one bit if a column in that
* row has been pressed
*
* PTH
* bits 7 6 5 4 3 2 1 0
* ------- -------
* what row col
* how? write read
*/
static unsigned char keyscan(void)
{
static const char Keys[12] = "123456789*0#";
register unsigned char key = 0, col, row = 3;
do {
row = (row + 1) & 3;
PTH = 0xF0 ^ (0x10 << row); /* write 0 to read row */
delay_nano(3); /* delay */
col = PTH & 7; /* read col back out */
} while (7 == col); /* no zeroed bits, no press, retry... */
col = (col >> 1) ^ 3; /* 6->0, 5->1, 3->2 */
key = Keys[(row << 1) + row + col];
delay_milli(20); /* debounce time... */
return key;

- 2006-03-28Erlang for C Programmers
Hmm. Erlang is interesting; I've noticed that folks in #erlang and on the mailing list try and use it
as a general-purpose programming language, often with less-than-excellent results. Erlang is well
suited for what it was designed -- writing highly available applications distributed over a network.
For instance, the Erlang virtual machine is designed to crash when any error or any unexpected/unhandled
condition occurs (every possible situation must be explictly handled).
Eshell V5.4.6 (abort with ^G)
1> Foo = fun(N) -> if N > 0 -> N end end.
#Fun<erl_eval.6.43886099>
2> Foo(1).
1
3> Foo(0).
=ERROR REPORT==== 30-Mar-2006::15:47:49 ===
Error in process <0.30.0> with exit value:
{if_clause,[{erl_eval,expr,3}]}
** exited: {if_clause,[{erl_eval,expr,3}]} **
4>
For something like a telecommunications network that must be rock-solid is a good thing; it helps test for completeness
(whereas a program in C or asm will error and happily chug along).
But for hacking and/or playing around, this is a pain in the ass. Also,
while Erlang deals well pre-defined tokens it is has weak string and parsing support.

So the other day someone piqued my interest about GMP, an arbitrary-precision math library
which i'd been aware of for years but never really had an excuse to use.
so i wrote some stuff using that; then someone in #php had a bot that'll execute code
(secure, really! ;D) but didn't have the GMP extension compiled in; also it would only
accept ~300 chars of input, which explains why the code is a bit dense.
so here's my own (crappy) arbitrary precision addition and Fibonacci sequence calculating
code. it is of course significantly slower than GMP, but i'm still proud of it :/
<?php
function add($a,$b,$x){while(ord($a[$i])||ord($b[$i])){
$t=$a[$i]+$b[$i]+$c;if($c=$t>9)$t-=10;$a[$i]=$t;$i++;
}$c&&$a[$i]=$c;$x=$a;}
function fib($n){$f=array("0","1","1");for($i=1;$i<=$n;
$i++){$j=$i%3;$k=($j+1)%3;$l=($k+1)%3;add($f[$k],$f[$l],
&$f[$j]);}return strrev($f[$j]?$f[$j]:0);} echo fib(
$argv[1]);?>

which I've been reading about a bit in relation to
instruction sets and all that fun low-level stuff... maybe i'll write a small set of
BCD routines in C just to get a feel for it.

I've made a lot of progress from scratch in 4 weeks, but this is not the first nor the most comprehensive offering out there. it uses apache 2.0, php 4 and mysql 4.1 and includes some nice features, such as customizable and flexible reports, html-based hitboxes for weapons, automatic calculation of gaming sessions, a decent collection of weapon and map images to aid in identification, completely automated updating and a simple, clean interface that works in all major browsers (and even passes w3c validation for html 4.01 loose :-P)

- 2006-01-14I use a Linksys WRT54G at home, which has a web config interface for, among other things, managing ports. The problem is that this stupid interface relies needlessly on some crappy javascript, and this crappy javascript does not work in any shell-based web browsers I could find (lynx, links, w3m). So I wrote a little config script of my own to log in and modify the port settings from the shell, using bash and cURL.

- 2005-01-03 i've finished my previous set of books, and have lots more to read. which is fine, because i am completely uninspired and have nothing to do whatsoever.
 The Difference Engine: Charles Babbage and the Quest to Build the First Computer is ½ nineteenth-century biography and ½ modern-day struggle to realize Babbage's design. this book took me longer to finish than usual... some of the details in the telling of Babbage's life drag on and i ended up skipping them. the modern half, the project by the Science Museum of London to construct the first full implementation of Babbage's Difference Engine No. 2 is quite interesting. this book does a good job of putting Mr. Babbage in his place. he designed a limited programmable computing machine... but is not the father of the modern computer. he was a very, very smart man... but not alone in mechanizing arithmetic in the nineteenth century. he visualized a working machine completely in his head... but failed to implement it.
