I encountered the same issue "File error: Cannot open load file, No such file or directory, bind-map" twice in my setup of spacemacs. The issue can be solved several ways which I found from github and clojurians-log.clojureverse.org. I consolidate the reasons and list them below. Timeout: the relevant setting in .spacemacs :- dotspacemacs-elpa-timeout 30 TLS Certs: emacs --insecure Permanent TLS Certs: the relevant setting in .

Chemical Bonding The Stable Electronic configuration of a noble gas An outer electron or outermost electron is also known as valence electron. Only outer electrons are involved in chemical reactions. In what way do noble gases behave differently from other chemistry ? Noble gases are unreactive because they have fully filled outer shells, that is, they have duplet or octet electronic configuration. How do atom achieve the electronic configuration of a noble gas?

States of Matter Matter is substance that has mass and occupies space. All living and non-living things are matter. State of matter: solid, liquid, gas Property Solid Liquid Gas Shape fixed not fixed not fixed Volume fixed fixed not fixed Compressibility Cannot be compressed cannot be compressed

The difference of two squared numbers $ a^2 - b^2 = (a + b )(a - b) $

Inside Atoms All matter is made up of atoms. Atoms are made up of subatomic particles: protons, neutrons and electrons. The protons and neutrons are tightly packed in the centre of an atom together from the nucleus of the atom. The electrons move rapidly around the nucleus.

I was not familiar with SIP states during the integration of VoIP products such as twilio, plivo and sinch. I am still confused about the state changes after reading documents. Here try to visualize the state change and help me to remember it. The state chart is based on my understanding. It is not necessarily correct. It is just for my reference.

Asynchronization is very hard. It brings benefits with several catches for backend programming. Here is serveral catches and respective solutions. However all those will increase the cost of developments. Hard to debug and trace As the process breaks down to serveral asynchronious subprocesses, it is very difficult to relate all information of the process when something goes wrong. An extra overhead correlation Id is needed to adopt to ameliorate this issue.
