Xeriar Re:File system? (45 comments)

Not a particularly useful use of the inode table. The filesystem is great for a few hundred or even a few thousand records, but when you're dealing with billions of records, that adds up to a lot of wasted space.

By Latest Count, 95% of Email Is Spam

Xeriar Re:Logic? (198 comments)

Right. They are ignoring the huge volume of legitimate mail that hotmail/msn silently deletes in violation of the RFCs.

Hotmail doesn't represent the majority of e-mail accounts, and usually it seems to be down solely to the incompetence of whoever is administering hotmail, rather than intentionally violating RFC. Same difference, I suppose, but it's certainly not a majority of the legitimate e-mail they get to them, anyway.

Drupal's Dries Buytaert On Drupal 7

Xeriar Re:Auto-update feature in Drupal 7 (55 comments)

Wrong - the auto-update feature is new to 7.x, so actual sites running 6.x (or earlier) doesn't benefit from it. Also, the new feature will only install and update modules and themes, not 'core', so I'm guessing updating core from 7.0 to 7.1 is probably going to require about as many manipulation steps as you need to go from 6.14 to 6.15. I don't have a lot of experience, but I would not say it's "extremely easy": the stable 6.x version requires you to do a lot of file and configuration manipulation just to go from 6.14 to 6.15 (if you follow all the recommended steps, which I did for my test site recently). It's not hard, it's just not automated.

If you set everything up properly, you just overwrite everything not in the sites directory with the new files, and then possibly run the database update script. Quite trivial.

I actually set up Drupal sites by symlinking to a main drupal installation for files and common modules. All the benefit of the /sites directory without having to use a single root favicon, deal with script-loaded sitemaps, etc.

The Environmental Impact of PHP Compared To C++ On Facebook

Xeriar Re:10:1... Really? (752 comments)

PHP's primary issue in the database department is it doesn't have a clean way of say, maintaining prepared statement declarations across connection instances. Which is frustrating. APC's handling of shared memory is not the best, either, and the memcached extensions for it need polish. Don't get me started on how PHP treats constants.

Where PHP really fails, however, is in memory usage. It takes up dozens of times as much RAM as a well-built C program would. Facebook would not reduce their computer count by a factor of ten because PHP is that much less efficient at its job, but because more memory would be available in a given machine to handle more instances at once.

Note: PHP 5.3 addresses a lot of this, but though I haven't tested it, I doubt the memory efficiency of PHP is going to get far into the double-digit percentiles of C++ in one shot.

Eolas Sues World + Dog For AJAX Patent

Xeriar Re:laughable (647 comments)

You could even consider such basic human decency to be an investment. If you give the guy without a coat one, he'll be a more productive worker in turn. And if he like you is not an asshole, you may get something out of it.

Health care is a particularly blatant example: we could insure every uninsured for the cost of denying insurance, several times over. The rest of the money would be sufficient to pull the US out of recession, merely through having enough of an edge in labor efficiency to eliminate our trade deficit.

None of those calculations make any assumption about having a more efficient work force along with a healthier work force. Every hour a poor person spends in agony is an hour they are not working to their fullest potential.

Spain's Proposed Internet Law Sparks Protest, Change

Xeriar Re:he said (103 comments)

i know that i matter. that you believe you don't matter is your own intellectual failure, not mine, and your resignation to your self-imposed helplessness is a resignation that only affects your sorry ass, and has no bearing on my rights and abilities as a free man of a liberal western democracy, which i fully comprehend, appreciate, enjoy, and practice. if my society fails into fascism, it will be no fault of mine, but by the unfortunate proliferation of weak spineless pessimistic fools like yourself who have already given up before any battle has even been fought

I would offer a correction. -You- don't matter. Your friends, connections, and the relationships you have built matters quite a lot. The article demonstrates that rather well - a lot of attention was generated very quickly. Never fight alone. More of the world is with you than you think.

LHC Has First Collisions After Years of Waiting

Xeriar There's a nice formula to show the world won't end (324 comments)

The formula: N(>E) = k(E + 1)^-a

N is impacts per second
E is the impact energy in in GeV
k is ~5,000 particles per steradian per square meter per second
a is about 1.6.

So the ground your feet occupy get a dozen or so such collisions per day, and so on.

Landmark Health Insurance Bill Passes House

Xeriar By Guaranteeing their pay (1698 comments)

The reason that deciding who gets healthcare on the basis of ability to pay is that what when demand for medical services goes up, the best way to get more providers of medical services is to increase what they get paid. Under this law, how will they increase the number of medical providers?

Nothing about public insurance prevents private operators - we don't want Canada's system after all - but there are real economic benefits to cutting people who do nothing but run interference against our own productivity out of the economy. Basic math: A rescission worker uses her own labor to interfere with the labor of both the doctor and the patient. Even ignoring the loss of efficiency due to ill laborers, and even assuming the doctor is not spending any time on hold (ha!), every unit of work you pay the person authorizing care interferes with a minimum of two people, for effectively no gain.

This ignores the moral problems involved in paying companies to deny care - denying a straight A surgical student preventative care for cancer, for example (a friend of mine). That only makes sense if you intend to restrict care to society.

Plenty of money available for health providers after we slaughter the hogs in the insurance and pharmaceutical industries. There could easily be a 15% gain in efficiency and a 15% gain in efficiency turns America into a net exporter again.
