From the mid-seventies all the way through until late-eighties, or perhaps even the early-nineties, if you walked into a computer lab youâ€™d come across a VT100 terminal. Towards the end there might have only been one or two wedged quietly in a corner, but they were there. These beige boxes were ubiquitous, and they survive today, at least in a way.
STMicroelectronics has just announced an upgrade to their STM32L4 Cortex-M4 microcontrollers with the new STM32L4+ series. The new chips operate up to 120 MHz, and have more embedded memoryâ€”up to 2 MB of flash memory and 640kB of SRAM. Aimed squarely at the connected device market, the power consumption of the new processor is low. In ultra-low power mode with just back-up registers active it draws just 20 nA without the realâ€?time clock (RTC), or 200 nA with the RTC.
My one frustration with the Raspberry Pi Zero is the fact that it doesnâ€™t have â€œrealâ€? USB ports. While I understand the necessity the idea of having trailing dongles hanging off the board always irritates me every so slightly. However the discovery that the USB bus could be accessed from exposed test pads on the underside of the board has more or less fixed this problem for me.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Musk AND Zuckerberg or Musk + Zuckerberg.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used). For example, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
