AMD Lists Threadripper 3000 CPU with 32 Cores, Possible New Socket

  • AMD posts preliminary new information on its forthcoming Ryzen Threadripper 3000-series processors.
  • As per normal, entries to this list may or may not make it to market, but it seemingly provides some very intriguing information about AMD's Ryzen Threadripper 3000-series (codename Castle Peak) processors.
  • Starting with the most obvious new information, AMD lists an unidentified Ryzen Threadripper with 32 cores and a 280W TDP (thermal design power).
  • As you recall, first-and second-gen Ryzen Threadripper processors drop into socket TR4, also called socket SP3r2.
  • The potential socket change could be attributed to the rumored support for eight-channel memory, so you might need to drop some cash on a new motherboard to expose the full features of some Threadripper 3000 models.
  • We won't have to wait long to find out as the Ryzen Threadripper 3000-series chips are scheduled to come out next month.

The pioneers of cultural anthropology who created “cultural relativism”

  • Now often called the father of American anthropology, Boas—Prussian-born, Jewish, and male—in fact exerted tremendous influence far beyond the academic discipline he helped to establish, presiding over a revolution in the social sciences and becoming one of the best-known public intellectuals of the first half of the twentieth century.
  • In hundreds of academic essays, as well as in his public writing and activism, Boas developed a view of human cultures that was at once empirically grounded and historically sensitive, emphasizing the socially contingent in place of the biologically determined.
  • The story he tells is not only about an important moment in the history of the social sciences, but also about a group of women whose travels across the American empire liberated them, in some measure, from the constraining norms of their time.

Any Fingerprint Unlocks Galaxy S10, Samsung Warns

  • The issue was spotted by a British woman whose husband was able to unlock her phone with his fingerprint just by adding a cheap screen protector.
  • Samsung said it was "aware of the case of S10's malfunctioning fingerprint recognition and will soon issue a software patch".
  • South Korea's online-only KaKao Bank told customers to switch off the fingerprint-recognition option to log in to its services until the issue was fixed.
  • Previous reports suggested some screen protectors were incompatible with Samsung's reader because they left a small air gap that interfered with the scanning.
  • After buying a £2.70 gel screen protector on eBay, Lisa Neilson found her left thumb print, which was not registered, could unlock the phone.
  • And when the screen protector was added to another relative's phone, the same thing happened.

Rejected from YC (Again)

  • Two months later we got an email saying that a partner would like to speak to us.
  • The call went well, Michael seemed to like what we're doing, as he himself had a long history working with video startups: Justin TV, which later became Twitch (sold to Amazon) as well as Socialcam (sold to Autodesk).
  • A few days after the initial call we got the email from YC inviting us to Silicon Valley to meet the partners for the final stage of the YC interviews.
  • We walked away feeling like we gave it our all and on the plus side, we had our first MRR and also the opportunity to run office hours with YC before the next batch.
  • Obviously, this feels like a blow as just 4 months ago we have been to interviews and took their feedback onboard.

Electric-Car Owners Hard Hit by California Power Shutdown

  • The affected area in Northern California surrounds Fremont, home of Tesla, and a great many electric-car owners who can't charge their vehicles as usual.
  • Tesla's Elon Musk is swapping in battery Powerpacks and solar power for Superchargers in the region as fast as he can get permits, he claims on Twitter.
  • On the second day of the outages, the Wall Street Journal reports 700,000-plus customers are without power in northern California, including areas such as the East Bay abutting Berkeley and Oakland.
  • Tesla owners may, in many instances, be better prepared for such outages than those without electric vehicles.
  • What's not so natural is running high-tension power lines across a populous state that's often done a brilliant job putting out fires to protect property and lives.

Scientists pinpoint neural activity's role in human longevity

  • The brain’s neural activity – long implicated in disorders ranging from dementia to epilepsy – also plays a role in human aging and life span, according to research led by scientists in the Blavatnik Institute at Harvard Medical School.
  • The study is based on findings from human brains, mice and worms and suggests that excessive activity in the brain is linked to shorter life spans, while suppressing such overactivity extends life.
  • The key in this signaling cascade appears to be a protein called repressor element 1-silencing transcription (REST), previously shown[2] by the Yankner Lab to protect aging brains from dementia and other stresses.
  • Immediately, a striking difference appeared between the older and younger study participants, said Yankner: The longest-lived people, those over 85, had lower expression of genes related to neural excitation than those who died between the ages of 60 and 80.

Guitar Machine

  • It is a “smart” or robotic attachment for a guitar that allows a human artist and a robot to share the act of playing the instrument.
  • Unlike many other automated instruments, Guitar Machine is not designed to replace the musician.
  • The hammering, bowing, tremolo picking, or electrically driven actuator components are controlled by the musician herself as an extension of her fingertips, merging the very natural human process of playing music with the computational power of machines.
  • A number of musicians have tried Guitar Machine, from music professors to jazz students, through sound effects designers, and more.
  • During those trials, I and my collaborator Abhinandan found that the robot helped them explore alternative sonic and musical spaces, effectively train complex musical patterns on the guitar, or even improvise along with the instruments.
  • The Guitar Machine not only showcases future applications for computation and robotics in creative domains.

Apple IIa – ROM for the Apple IIe That Compiles Basic (2018)

  • By the time I got ZBasic I had been writing code in BASIC on my TRS-80 Model III for a few years.
  • After my friend Brad Grantham wrote an Apple IIe emulator, the thought trickled into my head that I could implement an alternative history where BASIC programmers could actually write decent video games.
  • I ran out of room after implementing most of BASIC, having to leave out floating point and string support.
  • Of course a real ROM would need these, and I don't know whether re-implementing the compiler in assembly would free up enough room for them.
  • I'm okay leaving floating point out of my implementation because any program that used it would see a much smaller speed-up from compilation.
  • Also, the original ROM BASIC didn't have floating point and people were able to write video games just fine.

Show HN: Z shell configuration, zsh startup files, when they load, what they do

  • We use a Z shell configuration and directory naming conventions that help with compatibility, flexibility, and portability.
  • The default location for zsh system-wide files is in /etc.
  • The default location for zsh user files is in $HOME; this can be customized by setting $ZDOTDIR.
  • This repo contains our Z shell conventions for subdirectories and also our files that we like to use with multiple teams.
  • For an alias that is a one-letter shortcut, we use a naming convention for the file: the letter, an equal sign, and the result.
  • For example, the file g=git.zsh is the alias that sets g to run git.
  • For an alias that is intended to launch a program, we use a convention of trying probable locations for the tool.
  • For some of our systems, we prefer to install system-wide, so the repo files are available for all the system users.

Evidence of market manipulation on the Chicago Mercantile Exchange?

  • Three days earlier, in the last 10 minutes of trading, someone bought 82,000 S&P e-minis when the index was trading at 2969.
  • That same day, President Donald Trump said he would postpone tariffs on some Chinese goods, and the S&P index moved to 3016, or up 47 points since the fortunate person bought the 82,000 e-minis just before the market closed on September 10.
  • A week earlier, three minutes before the CME closed on September 3, someone bought 55,000 e-mini contracts, with the index at about 2906.
  • Federal regulators might start here: In the last 10 minutes of trading on Friday, August 23, as the markets were roiling in the face of more bad trade news, someone bought 386,000 September e-minis.
  • Three days later, Trump lied about getting a call from China to restart the trade talks, and the S&P 500 index shot up nearly 80 points.
