            Why isn't INT 31H set up properly even with a DPMI host active?
            Asked 2021-Mar-27 at 17:45

            I've been doing a lot of experimenting with assembly programming in MS-DOS. I've read that Windows 3.1 acts as a DPMI host for DOS programs, and that DPMI uses interrupt 31h for function calls.

            So let's give that a try. I open a DOS prompt in Windows 3.1...



            Answered 2021-Mar-27 at 17:45

            The Real/Virtual 86 Mode interface for DPMI is only interrupt 2Fh service 1687h. That returns an entrypoint which you can use to enter Protected Mode. Interrupt 31h services are only available in Protected Mode. Here's an example of a small DPMI client. Relevant code to enter Protected Mode:

            Localhost HTTP accessed from HTTPS webpage. Why no "Mixed Content" error?
            Asked 2021-Mar-18 at 13:32

            I make a HTTP request:

            • from a HTTPS JSFiddle: fetch('http://localhost:8090').then(...)
            • to HTTP localhost or

            And it works.

            No "Mixed Content" errors in Chrome (v89.0.4389.90) and Firefox (v86.0.1). Only Safari blocks the request. However, requests to 192.168.1.x trigger "Mixed Content" errors.

            Is localhost explicitly whitelisted in Chrome and Firefox? Or is it scheduled by browser vendors to be blocked with "Mixed Content" at some point, too?

            Can this be relied upon, for example, to control a local app bound to localhost that serves HTTP API?



            Answered 2021-Mar-18 at 13:32

            From MDN

            Browsers may allow locally-delivered mixed resources to be loaded. This includes file: URLs and content accessed from loopback addresses (e.g.

            • Firefox 55 and later allow loading of mixed content on the loopback address (see bug 903966),
            • Firefox 84 and later allow loading of mixed content on http://localhost/ and http://*.localhost/ URLs, as these are now mapped to loopback addresses (see bug 1220810).
            • Chrome also allows mixed content on and http://localhost/.
            • Safari does not allow any mixed content.

            Both and localhost are considered to be Potentially Trustworthy hence the browser can decide on the result.


            The behavior of Safari looks like a bug and it could change in the future. See a discussion here Don't treat loopback addresses as mixed content

            Upgrading react-scripts to 4.x.x breaks my app
            Asked 2021-Mar-17 at 16:04

            I have been developing a frontend app using React (v16.44.0, cannot upgrade to v17 yet due to a dependency), react-scripts v3.4.4, Typescript (v3.9.9) and React-Bootstrap (v1.5.1) for a few months and all is going well.

            However, react-scripts have been updated recently to a v4, and upgrading breaks the whole app. I am concerned with securities issues with react-scripts v3. I also would like to upgrade Typescript to v4+, there seem to be an incompatibility btw Typescript 4 and react-scripts 3 related to eslint. Various deprecation warnings are also stacking up.

            When I enable react-scripts v4.0.3, run npm start to launch the development server, Firefox (v78.8) throws:

            "ReferenceError: SharedArrayBuffer is not defined" in "node_modules/webidl-conversions/lib/index.js:347".

            Apparently webidl-conversions is required by bootstrap. I have searched about the SharedArrayBuffer issue, apparently it requires enabling additional headers, but I could not find how to add them using the npm start webserver.

            [Edit: upgraded Firefox to v86, still have the issue but I have not tried to configure it yet.]

            If I try with Chrome (v89), I have:

            "TypeError: Cannot convert undefined or null to object" on "node_modules/whatwg-url/dist/utils.js:48"

            which also seem to be required by Bootstrap.

            I do not have a dependency on Bootstrap per se, I use the react-bootstrap implementation. However, I use bootstrap-scss for the (S)CSS part.

            I can upload full stack traces if needed. Here is my package.json:

            Did you apply each migration described in the changelog?

            They also suggest you delete node_modules if you break your app when updating from 3.4 to 4.

            Fieldset with `max-height: 0` always overflows on Chrome v87+
            Asked 2020-Dec-07 at 21:51

            On Chrome 86, a fieldset with a max-height less than the height of its contents and overflow: hidden would hide the contents of that fieldset.

            However, on Chrome v87 (87.0.4280.67), this apparently changed.

            If a height is set that is less than the contents, then it correctly hides the overflow. This bug only appears with max-height.

            The following snippet will render correctly on Chrome v86 and earlier, Firefox, and Safari. On Chrome 87 the first fieldset will overflow.



            Answered 2020-Nov-25 at 13:14

            As a workaround you can add this to the fieldset:

            Using Kafka-Go, why am I seeing what appears to be batching reads/writes? Is there a config I am missing?
            Asked 2020-Nov-22 at 17:21

            I'm going to be switching from RabbitMQ to Kafka. This is just a simple spike to see how Kafka operates. I'm not sure if there are settings that I am missing, if it is my code, if it is Kafka-Go, or if this is expected Kafka behavior.

            I've tried adjusting the BatchSize as well as the BatchTimeout but neither have had an impact.

            The code below creates a topic with 6 partitions and a replication factor of 3. It then produces an incrementing message every 100ms. It launches 6 consumers, one for each partition. Both reading and writing are performed in go routines.

            In the log below, it goes 7 seconds without receiving a message and then receives bursts. I'm using Confluent's platform so I recognize that there will be some network latency but not to the degree that I'm seeing.



            Answered 2020-Nov-22 at 17:21

            You need to change ReaderConfig.MinBytes, otherwise segmentio/kafka-go will set it to 1e6 = 1 MB, and in that case, Kafka will wait for that much data to accumulate before answering the request.

            The problem is that you are clicking on the li element.

            Your click is received but no action is performed, in order to do so you need to target the a element after the li.

            Try this:

            ContinueButton = driver.find_element_by_xpath("//li[@class='nextPage']/a")
