Ordered list outside a block quote, with numbering that starts from 2:

1. Foo
2. Bar

Ordered list inside a block quote with numbering that starts from 2:

1. Foo
2. Bar

In the Hypothesis client, the start numbering of ordered lists is preserved. In the HTML output in the API and shown at https://hypothes.is/search, it is not.

Additionally in activity pages, there is a problem that the list bullets for ordered lists are not rendered, although the <ol> tags are present in the HTML.

Compare the rendering of this annotation in the client vs activity pages - https://hypothes.is/users/robertknight?q=url%3Ahttps%3A%2F%2Fhypothes.is%2Fdocs%2Fhelp%3Felife_test%3D1.

Hi Tom!

Thanks for sharing your feedback on Hypothesis UX at iAnnotate this year.

If you use the Hypothesis client with the “clean” theme I recommend using the data-hypothesis-trigger attribute to create a button or other affordance to open the sidebar. See https://h-client.readthedocs.io/en/latest/publishers/host-page-integration/ for details. This allows users to see comments without having to find a highlight.

See this GitLab issue for a real-world example of where this became a problem.

Since a few candidates have asked this, we're not wedded to Angular as a framework, but it was perceived as a sensible choice back in the early days of the project in 2013-2015. In more recent times we've had higher-priority technical issues to address.

Setting the future technical direction and helping to implement it is part of the role.

Broken link. I found a copy at https://github.com/yunjey/cs231n/blob/master/assignment2/cs231n/im2col.py

Corrected link for Python 3: https://docs.python.org/3/library/pickle.html

Keys generated using this command are trusted by browsers (I've tested with Safari, Chrome, Firefox).

I found that they were not trusted by SSL client libraries (eg. Python's ssl package or requests) which use openssl because the keyUsage setting is missing the keyCertSign flag.

Changing the keyUsage= section to keyUsage=digitalSignature,keyCertSign resolved the problem.

Should this say enable DoH under all circumstances? Presumably the current default, mode 0, is always off anyway.

We added a link to the privacy policy, terms of service and community guidelines on the sign up page. We added a checkbox that you have to tick before you can sign up.

In practical terms this means that we turned on Google Analytics' IP anonymization feature which zeroes that last octet of your IP address.

Almost certainly UTF-8 on macOS and Linux. I'm not sure about Windows.

It wasn't clear to me after reading this, but -*- coding: utf-8 -*- comments are redundant in Python 3 because the default encoding of files is UTF-8.

Quite interesting for Hypothesis.

About this demo

This is a test client which shows: 1) how to use OAuth to create customized Hypothesis clients and 2) is a prototype of support for H5P, a system for creating embed-able interactive content such as quizzes etc.

To add a new annotation with H5P content:

1. Log in to this client by clicking the Log In link and approve access when prompted.
2. Go to https://h5p.org/ and find a piece of demo content.
3. Click the "Embed" button at the bottom of any embed
4. Copy and paste the embed code into a new annotation or Page Note on this page.

Next, try creating your own interactive content on H5P.org and pasting embed links here.

🤠 - H5P content is sandboxed to prevent malicious abuse. Some functionality may not be available. Let me know if you find issues.

I'm not sure if this is still true, SQLite does have a SAVEPOINT command now. Whether SQLAlchemy supports it and whether there are any limitations with it I don't know.

We are trying to clarify in https://github.com/hypothesis/h/pull/4700#discussion_r153477745 whether search requests made after an index operation with refresh=true are guaranteed to see the change. My understanding from these docs is that this is true in ES 6.

Anyone know about earlier versions?

Interesting article on gzip compression. It explains how to apply knowledge about how gzip (and specifically DEFLATE) compression works in order to generate source text that compresses better.

Why "threatening"?

A "consciousness raising group". See this article.

The Wired article on the Monocle feature dates back to 2009. In 2017, it is still apparently a hidden feature in the Yelp app.

So basically all the discussions we have had within Hypothesis about rights to write over web pages will be had, but this time applied to the real world.

This article argues for the benefits of favoring integration ("feature") tests over unit tests. An opposing argument ("integration tests are a scam") is that reliance on integration tests is a bad idea because of the difficulty of covering all possible code paths with integration tests as opposed to unit tests.

A half-way point between the two views is the concept of a testing pyramid which advocates having end-to-end, integration and unit tests, but with a larger number of the latter and a smaller number of the former.

This might be useful for resolving an issue we have with Google Groups where replies made via Zendesk to support requests originating from emails to a Google Groups forum only go to the original user and do not appear on the Google Groups mailing list.

You can use this to observe all user interactions in an application for example.

Another EPUB annotation.

Should be "This operation ensures that"?

Quick foo

An annotation created using IE 11 when logged in using OAuth

So this means that the verifier parameter replaces the Authorization header?

This is a quick test of an annotation made on an EPUB document.

I initially tried without running this command but that failed - the plugin configuration had Hypothesis disabled. Presumably that means that the submodule references in the root project don't currently reference the HEAD of the develop branch in some of the submodules?

Here is an example of an annotation with an embedded video, taken from a page about Hurricane Harvey

This appears to be out of date. It looks like alembic commands should be run via the ./bin/hypothesis wrapper script. See https://github.com/hypothesis/h/issues/3863

./bin/hypothesis migrate revision -m "Add the foo table"

The "can't be changed later" part is something we could, and probably will want to at some point, address.

In a groups-first API I imagine that this might be a specific API call though, since there are a number of error conditions that are specific to this operation.

What is a Letraset sheet?

According to this GitHub issue the storage mutex was never implemented in browsers.

"Bring Your Own Buffer"

Saqib is blind.

I wonder how they try to avoid causing offence if the guess is wrong?

This should say 2.34 seconds. Kimeli was ~10 metres behind when Farah crossed the line.

It's not just "potentially annoying". I think our users would use somewhat stronger language to describe this hassle!

It is possible that the user's identity on the website changed since the last time they visited the page, in which case we do need a new access/refresh token.

I would be inclined not to try and solve this problem until we're sure it is a problem to avoid introducing fun new caching issues that cause confusion for us and users.

Presumably this would be true for any novel interaction environment.

Blah

I assumed that revoking the old token would be mandatory, but on the other hand, not revoking it allows clients to retry a refresh if they fail to receive the response the first time due to a transient network error.

A useful list of dependency injection frameworks for JS. From what I've seen of the packages listed here:

BottleJS looks like the simplest and least demanding in terms of JS engine features.

InversifyJS is heavily orientated towards TypeScript and assumes use of decorators, reflect-metadata etc.

Inverted is unmaintained and the link 404s.

I haven't yet looked at WireJS or Mocktail.

A caveat here is that we cannot tell whether annotations are annotations or orphans until after we try anchoring them, so if we go with this approach we'll either have to change how annotations in the "received but not yet presented to the user" state are handled, or optimistically assume that the annotations do anchor.

That definitely depends on what environments you are familiar with. In Windows (traditionally) and modern MS apps tabs are left-aligned.

Strictly speaking yes, although ARIA actually has dedicated roles for tabs. If you use those, I don't think it really matters.

They are tabs rather than buttons. I don't think they should necessarily need to look the same as buttons, as long as it is clear you can hit them.

I'm not clear on exactly what these three things mean and why they might be strong signals for a tracking domain. Can anyone clarify?

In the case of the sidebar, this is true. Do understand though that code in src/annotator fundamentally runs in an untrusted context and a sufficiently determined page could manipulate what that code does in pretty much any way it wanted.
