Relativistic hash tables, part 1: Algorithms [LWN.net]
One might wonder whether the resizing of hash tables is common enough to be worth optimizing. As it turns out, picking the correct size for a hash table is not easy; the kernel has many tables whose size is determined at system initialization time with a combination of heuristics and simple guesswor…
Xen Security Advisories

"XSA-108 2014-10-01 12:00 none (yet) assigned (Prereleased, but embargoed)"
I wonder what it is this time, given that AWS is pre-emptively shutting instances down and telling users their instances will be rebooted.

Careful with that Buffer… | OS/2 Museum
Last week I was sorting through several sets of Microsoft C 5.1 disks from 1988 (more about that later). While I was comparing the disk images to see whether the disks were the same or not, despite different labels and part numbers, I did a double take when I realized that a file with random e-mail…
Hasnain says:
"Random memory fragments such as those listed here can be found on many IBM and Microsoft disks, but usually they contain bits of directories or executables, not plain text of e-mails."

And THEN we're going to ..."
Brave New Phone Call
Ray Ozzie’s new app Talko hopes to give people their voices back
Hasnain says:
"No matter what happens to Talko, it is remarkable that a pioneer from the floppy disk days has created one of the year’s most innovative mobile apps. Back in 2000, Bill Gates noted that, of the early visionaries of personal computing, very few were still in the game. “Except for Jobs and myself and Ray Ozzie, it’s not very many people,” he told me. Fourteen years later, Jobs is dead and Gates is no longer a full-timer at Microsoft.
But Ray Ozzie is still building. And he wants to reinvent the phone call."

The colossal DEA failure that prevented a potentially major medical breakthrough
Once upon a time, researchers hoped to explore the promise of ecstasy for treating PTSD. Then the feds stepped in
Hasnain says:
"The drug that had been “mislabeled” as MDMA and proven so horribly toxic that it had stopped Michael’s study cold; the drug that was far more toxic than actual MDMA, methamphetamine, already was a prescription medicine."

Shirky: Ontology is Overrated -- Categories, Links, and Tags
Clay Shirky's writings about the Internet, including Economics and Culture, Media and Community, Open Source
Hasnain says:
Long, and worth reading for anyone who works or is interested in ontologies and classification.
"They missed the end of this progression, which is that, if you've got enough links, you don't need the hierarchy anymore. There is no shelf. There is no file system. The links alone are enough."
"One of the biggest problems with categorizing things in advance is that it forces the categorizers to take on two jobs that have historically been quite hard: mind reading, and fortune telling. It forces categorizers to guess what their users are thinking, and to make predictions about the future."

I Had a Stroke at 33
On New Year's Eve 2007, a clot blocked one half of my brain from the other. My reality would never be the same again.
Hasnain says:
I didn't know buzzfeed actually had content worth reading. This is beautiful, moving, and scary.
"I wondered if I’d betrayed any secrets, but when I stopped to consider them, I couldn’t remember my secrets."

The invasion of corporate news - FT.com
A population of 100,000 is no longer a guarantee that a city like Richmond, California can sustain a thriving daily paper. Readers have drifted from the tactile pleasures of print to the digital gratification of their smartphone screens, and
Hasnain says:
Native advertising and corporate-influenced media is kind of bad. The John Oliver video on this topic (https://www.youtube.com/watch?v=E_F5GxCwizc) is also great.

David Berreby – The obesity era
As the American people got fatter, so did marmosets, vervet monkeys and mice. The problem may be bigger than any of us
Hasnain says:
"Today’s priests of obesity prevention proclaim with confidence and authority that they have the answer. So did Bruno Bettelheim in the 1950s, when he blamed autism on mothers with cold personalities. So, for that matter, did the clerics of 18th-century Lisbon, who blamed earthquakes on people’s sinful ways. History is not kind to authorities whose mistaken dogmas cause unnecessary suffering and pointless effort, while ignoring the real causes of trouble. And the history of the obesity era has yet to be written."
