worth one's salt




You might think of salt as nothing more than the inexpensive stuff that tastes good sprinkled on French fries and popcorn, but in fact it’s far more than just a seasoning and has a long history as a highly prized substance. Today, there are reportedly more than 14,000 known uses for salt. Not only does the human body need it to function properly, but salt also is utilized for everything from producing chemicals to deicing roads.

Before the days of artificial refrigeration, the main method for preserving food was to treat it with salt. In this way, salt came to represent power; without it, armies couldn’t travel great distances and explorers couldn’t sail to new lands because their provisions would spoil. Throughout the ages, a variety of cultures also used this mineral in ceremonies and religious rituals. For many centuries, until salt deposits were discovered throughout the world and extraction methods improved, salt was scarce, which made it more valuable.

In some ancient societies, roads and cities developed as a result of the salt trade.

The expression to be worth one’s salt, which means you’re competent and deserve what you’re earning, is most often said to have its roots in ancient Rome, where soldiers were sometimes paid in salt or given an allowance to purchase it. The word salary is derived from the Latin “salarium,” which originally referred to a soldier’s allowance to buy salt.

take something with a grain of salt




The eclipse is just one week away, and we are at the point where forecast models can start piecing together the general weather pattern for Aug. 21. However, not until about three to five days before the eclipse — or even later — will regional details start to come into focus. So we still must paint the cloudiness outlook with very broad strokes. Continue to take it with a grain of salt, and we would not recommend altering plans based on it.

iPhoneを使った不遜な・・・ ー flash


There’s a new iPhone craze on the subway, and it’s not the latest Candy Crush update.

New York women have discovered that creepy men are using the iPhone AirDrop app to send them photos of their privates while on the same train.

Since more straphangers using the MTA are carrying advanced iPhones and awareness of the AirDrop app has increased, local straphangers have started noticing a troubling trend first reported in London in 2015.

Britta Carlson, 28, was riding the uptown 6 train to a concert on July 27 when a mysterious message popped up on her smartphone.

“iPhone 1 would like to share a note with you,” read the note sent at 6:51 p.m. She hit “Accept” and was horrified by what she saw. “It was just a huge close-up picture of a disgusting penis,” said Carlson, of Bushwick, Brooklyn. The message was titled “Straw” and was sent by an anonymous stranger.

“It really felt like someone had actually just flashed me.”

A California man filed a stomach-turning lawsuit against Heineken beer and Kroger supermarket — claiming he sipped suds loaded with dead, canned geckos.

George Toubbeh said he got violently ill and “suffered from extreme anxiety and post traumatic stress disorder” from the beer he purchased and drank on Aug. 7, 2015, according to his lawsuit filed in Orange County Superior Court.

“Plaintiff consumed the Heineken beer and noted that the beer had a foul taste,” his lawyer Zahra Aziz wrote. “Immediately thereafter, plaintiff experiences severe abdominal pain followed by vomiting,”

そのUSB、危険かも ― crosstalk leakage


USB connections are prone to leaking data, according to a group of researchers from the University of Adelaide.

The researchers are presenting their finding at the USENIX Security Symposium in Canada.

“We have tested over 50 different computers and external hubs and found that over 90% of them suffer from a crosstalk leakage effect that allows malicious peripheral devices located off the communication path to capture and observe sensitive USB traffic,” states the abstract of their paper, USB Snooping Made Easy: Crosstalk Leakage Attacks on USB Hubs.


The researchers used a USB-connected novelty lamp to read key strokes from a USB keyboard plugged into an adjacent port using the voltage fluctuations of the port’s data lines. Data was sent to another computer via Bluetooth.
(Rohan Pearce. Researchers reveal crosstalk USB security threat. Computer World. August 10, 2017.)

その仕組みというのは"crosstalk leakage"というものを悪用したものだそうですが、"crosstalk"という単語を知りませんでしたので辞書を引くことに。


記事をお読みいただければ分かりますが、"crosstalk leakage"とは、USBキーボードなどを使った場合に漏れてくる微妙な電圧変化や電波のことで、USBキーボードとは別に取り付けられたUSBデバイスでこれらを捉えてキーストロークの情報を盗み取ったりすることができることが実験の結果確認されたそうです。
