_cbsz··on Lisp interpreter in 90 lines of C++
Graders at the University of Michigan are willfully unaware of it because we want students to have some coding style. You'd be surprised how many have to be repeatedly slapped around until they get a real programmer's editor instead of trying to use gedit without configuring it.
_cbsz··on Who Wants Parallel Computers?
I'm a little confused about what point the article is trying to make. I don't think that the many-core folks have ever said that they're building many-core because people want it; I've consistently heard that it's because of Moore's Law collapse, as admitted in the article.

If it were economical to produce faster uniprocessors instead, you can bet that chip companies would do it, because they'd make more money that way.

_cbsz··on What Does Haskell Have to Do with C++?
Oops! I meant that Google didn't turn up anything for TeX, not Perl. The Perl stuff is indeed well known.
_cbsz··on Can Anything Stop The Facebook Juggernaut?
> Microsoft, as it exists now, is a vehicle for selling Windows and Office licenses.

What about the (rather successful) Xbox 360, which you mention in the very next paragraph?

_cbsz··on What Does Haskell Have to Do with C++?
A quick Google doesn't turn up any pages stating that parsing Perl and CL is undecidable. Can you provide a reference?
_cbsz··on Hacker's Guide to Tea

_cbsz··on A Google Interviewing Story
It's impossible to do in O(1) in the worst case, because you have to at least examine all the input (e.g., if the input matches the regex AA*B.)
_cbsz··on Do you read HackerNews all day and never actually do anything?
Microsoft.
_cbsz··on When we got to the scanner, I opted out. Then they opted out.
I thought it was established on HN that that letter about safety had been properly addressed (it's from April).
_cbsz··on Facebook’s Gmail Killer, Project Titan, Is Coming On Monday
This should actually mean I don't need to visit facebook.com anymore if there is indeed POP3 or IMAP access, because (presumably) they will send full messages to Titan rather than the current "you have a new message NOW CLICK ME", and POP3 access to Titan means that I can get Facebook messaging through GMail.

The catch is probably going to be a lack of SMTP...

_cbsz··on Hidden Debug Mode in AMD Processors
Cached version, via Slashdot: http://webcache.googleusercontent.com/search?q=cache:EzsEFco...

Make sure you choose "text-only version" in the upper-right.

Looks like it's just hardware conditional breakpoints, nothing to see here...

_cbsz··on Go (lang): one year ago today
C came from Bell Labs; it's not entirely clear to me that an industry research lab counts as academia.
_cbsz··on This is why sites choose to stay vulnerable to Firesheep
I am not going to argue for the correctness of this position, but presumably it's because the "secure" icon (e.g., the little lock) is absent.
_cbsz··on This is why sites choose to stay vulnerable to Firesheep
The warning isn't spurious, by the way. A man in the middle could inject evil JS into urchin.js (or whatever the equivalent is now) just as easily as he could inject it into your site's JS; the page is not secure.
_cbsz··on The Ten Commandments for C Programmers (Annotated Edition)
Why is that good? It also doesn't solve:

    int *p = malloc(LOTS);
    int v = read_from_network();
    int o = read_from_network();
    p[o] = v;
if that malloc fails, for example.
_cbsz··on Evilgrade is like Firesheep for Software Updates
A secondary method for authenticating updates would also be wise. When Moxie Marlinspike's null-prefix SSL bug landed, people with vulnerable versions of Firefox were somewhat screwed: Firefox used only SSL to ensure the authenticity and integrity of updates, but SSL was broken, so the update fixing SSL security couldn't be authenticated!
_cbsz··on Ask HN: Anyone else here struggle with the alcohol?
I hate to be HN's resident word Nazi, but you want to s/reign/rein/. "Reign" is roughly "to rule", where as "rein it in" is a reference to the reins used to make a horse stop.
_cbsz··on Google Engineering Management Mistakes
Is "close to 50%" the going marginal tax rate in general? I calculate ~30% federal + ~10% California + possibly ~6% social security & Medicare to get that number; did I miss anything? (current grad student with a marginal rate a lot closer to 20%, haven't had the joy of full-on taxes yet)
_cbsz··on The Day US Customs Found A Bullet In My Pocket
Still doesn't hold. Idaho is neither a separate country, nor, more importantly, is it home to established organizations with ties to the government of said separate country, overtly dedicated to terrorist activity founded on extremist beliefs. Renting trucks isn't particularly analogous with flying to such a place. Policemen are not customs agents at a border crossing.
_cbsz··on "Rate My Startup" Post Policy
This is actually a case where "Cue", not "Queue," is correct.
_cbsz··on The Day US Customs Found A Bullet In My Pocket
Your analogy does not hold, as the guy was not prevented from doing anything. He was questioned, searched, and spied on by the FBI. As far as we know, no direct, material harm came to him.
_cbsz··on The Day US Customs Found A Bullet In My Pocket
It's not entirely clear to me that I don't want a person who crosses our borders in the circumstances that the author of the article did and carrying the things that the author of the article carried grilled to see if he cracks. Can you imagine what would happen if someone carried those things across a border, did NOT get grilled based on the "would be really inept" arguments, and then committed a terrorist act? We'd be calling for the screeners' heads, and quite probably would be right to do so.
_cbsz··on The Day US Customs Found A Bullet In My Pocket
http://en.wikipedia.org/wiki/Synecdoche is probably the term, although the context in which "synecdoche" is used is generally analysis of literature / "English class."
_cbsz··on The Day US Customs Found A Bullet In My Pocket
You forgot the implied "...and then cross an international border while carrying said journal entry."
_cbsz··on Tell HN: Uptick in mean-spirited comments
A flaw: I might vote neutral as "I agree with this comment's current point value." In that light, 20 up, 5 down, and 500 neutral is a fairly confidently ranked 16-point comment, but 20 up, 5 down, and 0 neutral is not. However, the less confident one should be "floated" to a small portion of users to get more votes.
_cbsz··on "Dead Drops" is an anonymous, offline, p2p file-sharing network in public space
I think USB-based DMA attacks were used against the Xbox 360, but I don't have a source off the top of my head.
_cbsz··on For the First Time, the TSA Meets Resistance
Congressman, n. A man who is a member of the U.S. Congress, especially of the House of Representatives.

_cbsz··on For the First Time, the TSA Meets Resistance
Senators are Congressmen. Did you mean your representatives?
_cbsz··on Using the Cython Compiler to write fast Python code
Cython is not a bad story for C interop, though. See e.g. pyevent (http://code.google.com/p/pyevent/), which provides Python bindings to libevent. Be warned: until there's a new release of pyevent (0.4), you should, in my opinion, use the SVN version.
_cbsz··on Poll: OkCupid stories
Despite the possibility of getting trolled: using two condoms increases the risk of failure vs. using one. Don't do it.
