Inside impl<P, E, L> PrefixExtender<P, E> for (Rc<RefCell<GraphFragment<E>>>, L) , count uses an undefined variable prev.0.

The sentence explaining the graph representation is very hard to parse: "We will represent a fragment of graph by a list of destinations and offsets into this list for each vertex." Can you give some examples? How do you represent a graph with just 1 triangle?

At the end of your excellent blog on 'Memory Management for Big Data' (https://github.com/frankmcsherry/blog/blob/master/posts/2017-07-27.md) you mentioned using your recycler project.

I shared your blog with some colleagues, and their feedback on this point was:

"I also followed the link to have a look at ‘recycler’. It seems like a small Rust shortcoming that it’s worth having a library whose main purpose is to provide typed memory caching. I would think (hope?) that the Rust allocator would be clever enough (in terms of releasing/acquiring memory to/from the OS) to make this a fairly limited optimisation.
I notice the ‘recycler’ code is fairly old and wonder if this is still a worthwhile procedure?"

and:

"Yeah 'recycler' looks like another memory allocator ... I wonder why that would be useful."

If you have a moment to elaborate on how the recycler helps here, would be very grateful. Thanks!

The link titled "better versions" which links to an improved algorithm for PageRank is broken. I believe the URL below refers to the same paper:

To the most recent post (3/11/18):

"it its input" -> in its input
"addivitely" -> additively
"computaton" -> computation.

Enjoyed reading it!

Here is extract from a article I am writing. This is the part about you:

Hi,

Your old blog site doesn't link here, which creates the impression that you haven't posted since 2015.

You might want to add a 'moved to github' post so that people can find your recent content.

Hi,

The way you're doing your blog now makes it hard to follow if you're using a feed aggregator (like I am) to follow the posts, as they get lost in all the formatting/correction commits.

Although it's not a terribly clean solution, it would help if you kept a separate branch and git merge --squash-ed the changes every time you finished a new blog post.

Links to 2018 posts contain 2017 in them instead (like https://github.com/frankmcsherry/blog/blob/master/posts/2017-05-19.md).

https://github.com/frankmcsherry/blog/blob/master/posts/2015-12-24.md

can you share some links for code in python for posts/2015-12-24.md

pls???
