      令人惊讶的是:FBI只能够捕获收到的消息,而无法获取已发送的消息。这揭示了iOS系统在通知数据存储方面的一个不对称设计 - 只缓存接收到的通知内容,而不保存发送的通知。这种设计差异可能源于系统对电源和存储效率的考虑,但也为执法调查提供了有限但有价值的数据来源。

    1. With specific keyword messages you can compute the Least Common Multiple and Greatest Common Divisor. A keyword message is composed of one or more colons “:” to insert one or more arguments:

      A source of confusion for beginners is why binary messages exist in the first place when they could be implemented instead as keyword messages taking one argument as #lcm: and #gcd:; you could in fact, imagine an alternative syntax with only unary and keyword messages, but it would be cumbersome to read and write. Binary messages improve legibility without introducing too much complexity for the implementors.

    1. Acknowledgement: Great thanks to Chris Aldrich who saw the Quote Investigator article about the saying “We shape our tools, and thereafter our tools shape us”. Aldrich notified QI of the germane quotation examined in this new article. Aldrich pointed to its presence in “Walden”. This led QI to create this article and to update the existing article.

    1. We need to read the Signature header, split it into its parts (keyId, headers and signature), fetch the public key linked from keyId, create a comparison string from the plaintext headers we got in the same order as was given in the signature header, and then verify that string using the public key and the original signature.

      ```ruby require 'json' require 'http'

      post '/inbox' do signature_header = request.headers['Signature'].split(',').map do |pair| pair.split('=').map do |value| value.gsub(/\A"/, '').gsub(/"\z/, '') # "foo" -> foo end end.to_h

      key_id = signature_header['keyId'] headers = signature_header['headers'] signature = Base64.decode64(signature_header['signature'])

      actor = JSON.parse(HTTP.get(key_id).to_s) key = OpenSSL::PKey::RSA.new(actor['publicKey']['publicKeyPem'])

      comparison_string = headers.split(' ').map do |signed_header_name| if signed_header_name == '(request-target)' '(request-target): post /inbox' else "#{signed_header_name}: #{request.headers[signed_header_name.capitalize]}" end end

      if key.verify(OpenSSL::Digest::SHA256.new, signature, comparison_string) request.body.rewind INBOX << request.body.read [200, 'OK'] else [401, 'Request signature could not be verified'] end end ```

    1. Why is the title of the book “The medium is the massage” and not “The medium is the message”? Actually, the title was a mistake. When the book came back from the typesetter’s, it had on the cover “Massage” as it still does. The title was supposed to have read “The Medium is the Message” but the typesetter had made an error. When Marshall saw the typo he exclaimed, “Leave it alone! It’s great, and right on target!” Now there are four possible readings for the last word of the title, all of them accurate: “Message” and “Mess Age,” “Massage” and “Mass Age.”

    1. only about 1% of carbon atoms are C-13. These are the only ones picked up by this form of NMR. If you had a single molecule of ethanol, then the chances are only about 1 in 50 of there being one C-13 atom in it, and only about 1 in 10,000 of both being C-13. But you have got to remember that you will be working with a sample containing huge numbers of molecules. The instrument can pick up the magnetic effect of the C-13 nuclei in the carbon of the CH3 group and the carbon of the CH2 group even if they are in separate molecules. There's no need for them to be in the same one.

      the author believe that even though the percentage of C-13 is low, but its NMR signal can be captured.

    1. I miss the thriving blogging culture of circa 1999-2012. People blogged before and after those dates, but that was a period where blogging really had an outsized voice in shaping political and cultural conversation.

      Maybe it's the fact that there's more thoughts, ideas, and actual conversation in longer form media? Too much has moved to social media which really immediately implies small, bite-sized bits of information---a short note, a photo, a star or a heart.

    1. “Don’t let them do it!”wailed Peter at the ceiling, as if he was talking to the house, the nursery. “Don’t let Father kill everything.”He turned to his father. “Oh, I hate you!”“Insults won’t get you anywhere.”

      It is against the rules that technology affects people so much that children become more attached to it than their parents

    1. "Make no mistake, we are losing trees all around the U.S., and cities are struggling to keep up with restoring and establishing a healthy, thriving tree canopy," says Dan Lambe, president of the Arbor Day Foundation.

      the message for this is losing trees.

    1. MQTT

      Message Queuing Telemetry Transport MQTT protocol -> publish-subscribe network protocol that transports messages between devices, usually through TCP/IP

      Protocol defines 2 network entities:

      1. message broker -> receives messages from clients and then sends them to any clients subscribed to topic.
      2. a number of clients ->
      <table style="border: 1px solid black;"> <tr> <th style="border: 1px solid black;"> MQTT un-encrypted port </th> <th style="border: 1px solid black;"> MQTT encrypted port </th> </tr> <tr> <td style="border: 1px solid black;">**1883** </td> <td style="border: 1px solid black;">**8883** </td> </tr> </table>
