   • Do people still use Ajax for a web applications?

     Top Answer

     Answered Jun 24, 2018 · 14 votes

     Yes, AJAX (XHR) is used all the time in web pages. It is still the primary way that JavaScript in a web page makes an in-page request to a server.

     There are now also WebSockets, but AJAX (XHR) and WebSockets have different characteristics for largely different purposes (with some overlap).

     There is also now an additional interface fetch()

     for making Ajax calls which makes some things a lot easier than before and this interface is promise-based rather than just using plain callbacks.

   • Do computers still use the Z80 CPU?

     Top Answer

     Answered Nov 05, 2017 · 4 votes

     Yes, the TI-84+/TI-83+ line of graphing calculators (besides the CE, which uses the faster eZ80 processor) use it: https://en.wikipedia.org/wiki/TI-84_Plus_series

     Zilog still appears to sell the Z-80 though it does look like they're mostly selling the eZ80 in that line which is compatible but much improved.

     Hobbyists still use it and there is even a kickstarter for building a ZX Spectrum clone: https://www.kickstarter.com/projects/1835143999/zx-spectrum-next However, they don't technically use the Z-80 but a 100% programming compatible clone using an FPGA. Certainly that's still a Z-80 as far as the programmer is concerned.

     Terminals are widely used, and will be used. The reason is that, when used skillfully, they're far more powerful than any GUIs.

     No, such questions are not very relevant, but yes, people use std::cin and std::cout all the time. Even the ones who design graphical interfaces may use cout for debugging !

     Yes, as long as console applications exist, cout and cin will exist.

   • Do we still use api endpoint health check in Kubernetes

     Top Answer

     Answered Feb 12, 2022 · 3 votes

     You can refer to these docs for an explanation of how "health checks", or probes as they're called in Kubernetes, work. For your question you may be particularly interested in the section on HTTP probes.

     You can pick any HTTP path of your application for these probes, while indeed /healthz, /livez and /readyz are common ones and happen to be the ones used by the Kubernetes API server (with, as you found, the /healthz one being deprecated in favour of the more specific alternatives).

     So, to implement health probes, simply add a GET route for each of the probes you'd like to the application and make sure the status code returned is 2xx or 3xx to signal a healthy state, or anything else when Kubernetes should consider the application unhealthy.

     Any code greater than or equal to 200 and less than 400 indicates success. Any other code indicates failure.

     In my opinion, it makes sense to return HTTP 200 for success and 500 or 503 for failure.

     Once your application is set up to respond accordingly to the prober, you should instruct Kubernetes to use it by adding something along the following lines to the container exposing your API in the PodSpec:

     livenessProbe: httpGet: path: /your-liveness-probe-path port: 8080

     If I understood your question regarding the probe failing for the /supersecret path, ignoring the indentation error in your YAML definition, this is most likely because that route requires authentication. The probes you have defined do not supply that. For this, you may use httpHeaders:

     readinessProbe: httpGet: path: / port: 5000 httpHeaders: - name: Authorization value: "Bearer secret" initialDelaySeconds: 20 periodSeconds: 5

     However, it is in my experience more common to not require authentication for your probe routes, but instead, to not expose those to the public internet (or even on a separate port). How to accomplish that is a whole different story and depends on how you are exposing your application in the first place, but one way could be to have an ingress with appropriate "ingress rules".

     On a more general note about troubleshooting failing probes: running kubectl get events is a good starting point.

   • Do I still need to use type='text/javascript'?

     Top Answer

     Answered Sep 03, 2012 · 2 votes

     No, that is the default value, if the attribute is absent:

     From the specification:

     The type attribute gives the language of the script or format of the data. If the attribute is present, its value must be a valid MIME type. The charset parameter must not be specified. The default, which is used if the attribute is absent, is "text/javascript".

   Now, most people now just use fetch and return JSON from the server. Ironically the most popular library, axios, still uses XMLHttpRequest, and a large part of the JS community push it as a better way to run things.

   How does Ajax work in JavaScript?

   • Most AJAX requests in JavaScript don’t load whole web pages as we did with our example. The data is sent and retrieved in a format called JSON, a text-based format to represent data, and more JavaScript code is used to format this data as HTML and print it to the page. For example, the data sent to log in to a website would look like this in JSON:

   May 15, 2011 · AJAX, or (A)synchronous (J)avascript (A)nd (X)ML (which interestingly enough tends to use JSON more these days), is a system in which Javascript uses a browser object to communicate with a remote server.

   Code sample

   $.ajax({

     url: '/server.php',

     dataType: 'html',

     success: function(html) {

     $("#mydiv").html(html);...

   Apr 29, 2016 · Ajax is a method of transferring HTTP data in a web browser without refreshing the page. It can sometimes be spelled as an acronym (AJAX) where the letters stand for Asynchronous JavaScript And XML. The concept was designed by Jesse James Garrett and really picked up steam in the mid-2000s.

   Ever since Ajax was introduced long back, the technology has evolved beyond its earlier definition. For example, the data interchange format for the Asynchronous communication has geared towards JSON rather than the verbose XML (the X in Ajax is for XML). A web developer must understand AJAX well.
