Article evaluation (Operational transformation)

The history section seems lacking and vague "Several years later, some correctness issues were identified and several approaches were independently proposed to solve these issues, which was followed by another decade of continuous efforts of extending and improving OT by a community of dedicated researchers."

The cc model seems to be lacking in detail and the csm model seems to lack completely the explanation why it was developed.

There should be a section that have some products that uses different operational transformation models.

Most of the citation used research papers on the topic.

Citation 15 is marked as a permanent dead link.

Citation 35 is a dead link as ShareJS is renamed to ShareDB. It is also used to quote a personal opinion.

Citation 35 and 36 are both opinions from researchers that researched alternative tech so there might be biases for their opinion on OT. At least direct quote is used, but does not mention the author's involvement or background.

Behind the scenes, there were arguments on how much criticism to include in the article and how valid those are. There seem to be differing opinion on such topics.

Microsoft groove also threw a curve ball in their approch to the problem that is slightly different then OT.

It is also hard to describe the problem in easier terms.

This is a B class article and is a part of WikiProject Computer science.

It seems like most of the discussion are on the criticism and not much talk at all on the other sections of the page.

Article selection (Persistent object store)

The article is lacking in information. Could use a history section, examples, pro and cons, comparisons with other stores. There needs to be information on development and changes that happened. There's not many sources of information.

There's only one citation that cites the paper that came up with this idea. Not a good source. Need more secondary sources.

Most of the first part of the article does not have citation.

Article selection (NiceHash)

Can use history and news section. There's not much information on the breach that happened. Can talk about payout and the difference between internal and external wallets. There have been blog posts from nicehash about how the internals of nicehash is and can be added to the page.

Most of the citations on the site is about the breach and there's much much information and or news otherwise. There can be a section on how the program works with interface direction, mining output examples.

List different mining algo supported by nicehash. separated by gpu and cpu algo.

Article Selection (Mmap)

The example here is really bad at explaining what mmap does and how to use it. There can be more technecial talk about how mmap works and what makes it different from using malloc. There can be further discussion on uses of mmap and why it is introduced and why it is necessary. There can be example code that uses different aspects of the uses of mmap.
