Unto the pure, all things are pure

I have a brand new Asus K501U laptop. It comes with a measly 16GB m.2 SSD (D:). I am glad for that because it means not paying an expensive premium for more. Windows 10 was on 2.5" 1TB hard drive (D:), and it was almost unusable (after having been using a SSD for Windows for more than a year) with the non-stop disk thrashing. It was a 30-second wait for the Start menu to show after pressing the Windows key. I bought myself a Samsung 850EVO 500GB SATA M.2 for less than US$200. It installed easily (I took the risk of leaving the battery online because I couldn't figure out how to remove that battery connector) and it was totally compatible. Asus kept reminding me that installing my own M.2 SSD voided the warranty. However, there were no stickers or seals so I could put back the original 16GB one if I ever need to seek servicing. My goal was to use the M.2 SSD for Windows (C:) and then to move the 2.5" 1TB SSD  with my data over from my old PC. The darn thing was tha...

Reference: https://developers.facebook.com/docs/messenger-platform Handle all data types in the callback There is only one callback url for all Messenger events. The type of callback (for example when a message is submited by a user to your page) is determined by the data payload attached to the POST callback to your url. There is no clearly obvious field in the data to identify the type of callback. It is necessary to unravel the json object received to figure out what type of callback it is. Depending on the language you are using for your web coding, it may be straightforward or complicated to even find out which json class the payload belongs to. The Facebook documentation does not specify the various json formats the Webhook can send. It merely gives one example each of the five types listed. There is minimal or no description of what each data field mean. You are expected to figure out from their English field names. Design your code to handle gracefully all json data...

Imagine your email software has this feature: As you are reading an email you are corresponding with person A, there is a Add button. By clicking it and selecting another person B, all the emails you have with person A in the past are immediately forwarded to person B, without warning. The email forwarding is executed virtually. Instead of physically forwarding each mail one by one to person B's mail server, basically your mail software gives access to Person B, at his own leisure, to browse EVERY of your email with person A. If you had done this by mistake, there is no process to cancel because the "forwarding" process is complete the moment person B is selected. There is no Undo option. You can scream and run round the room, but person B will continue, at any time in the future, to be able to read EVERY single email you had with person A. If you are a careful person that would never do such a silly thing, person A could click the Add button and the outcome will be...

Unless it's OK for your EVERY message to be published to the whole world, Facebook Messenger must not be used for any group conversations. I am referring to Facebook chat groups, not Facebook groups. There are basically no options to control Facebook chat groups. Any member of the conversation can add any person, Friend or not, to an existing conversation! So, even if there were no ill intentions, an accidental addition of someone else means TOTAL COMPLETE leakage. Even if you Remove that unintended person immediately, that person can view the WHOLE conversation, every message , since the group was created. There is no way to stop this . In the first place, while you can easily Add a person to a conversation from www.messenger.com, there is no way to Remove him or her on this same site. You have to do it from the Messenger app from the phone or facebook.com. Removal of a participant merely stops new messages from going to that person. He or see can still continue to se...

I did not take out my calculator when I wrote this, but I think it will help a skeptical world if we can gather more evidence of what happened between 4,000B.C. and 3,000B.C. Which of and how did Shem, Ham or Japeth become your great, great... grandfather? How did the two kangaroos on the ark land in Australia? The answers are meant and waiting to be discovered.  "It is the glory of God to conceal things, but the glory of kings is to search things out." - Proverbs 25:2 ESV
