Validity of in-line help content over time as users graduate from novice to Intermediate stages

This is a question in regards to an Enterprise product.

Consider a selection menu –

Option 1

help text (2 liner max)

Option 2

help text (2 liner max)

Option 3

help text (2 liner max)

Notes –

1) This help text was added below the Options as there was feedback from new users that the Option Label itself was not sufficient to communicate the intent of the option.

2) Advanced users have come back saying that they do not need to see the help text every time as they are well aware of the options. This is very much understandable.

Questions –

Our product has both ends of the user expertise spectrum fairly distributed. Also, let’s note that users graduate overtime. A tooltip cannot be used as we have seen very less usage of the same and creates extra friction for new users, compared to immediate help. Considering that standard interaction design principles recommend designing for the ‘Intermediate User’ (Alan Cooper, Dan Normal) – is tooltip the only way out? Or are there other thoughts?

Please advice. Thanks!

Can I copy individual stages of a SharePoint 2013 list-based workflow?

I have a SP 2013 list with a list-based workflow. Next release, I create a new list with the same content type. I want to re-use the list-based workflow but must implement a work-around to do this. I want to simply copy the stages in the first workflow into a new workflow and then associate the new workflow to the new list. It seems to work. Do you know of any issues doing this?

I cannot work with a reusable workflow because that does not recognize the content type fields and in 2013 you cannot successfully base a workflow on a content type.

Thanks, Linda

Recurrent relation for algorithms with two stages

I am trying to do the recurrence relation for my algorithm, but it has two variables $ T(n,m)$ . For sufficiently small $ n$ , $ m$ is practically the same as $ n$ , but $ m$ cannot grow beyond some constant $ k$ . So once $ n$ grows beyond $ k$ , $ m$ turns to constant $ k$ . So it has two different stages.

I have done the relation in both cases: when $ m$ is another variable, and when $ m$ is a constant, but how do I put them together?

Using $ a=2, b=2$ as an example: this recurrence relation with $ m$ as a variable like $ n$ : $ $ T(1)=1$ $ $ $ \begin{equation*} \begin{split} T(n) & = 2T(\frac{n}{2})+m \ & = 2T(\frac{n}{2})+n\ & = n+nlog_2n \end{split} \end{equation*}$ $

Treating $ m$ as a constant: $ $ \begin{equation*} \begin{split} T(n) &= 2T(\frac{n}{2})+m \ &= n+mn-m \end{split}\end{equation*}$ $

Please feel free to check my math. Now how do I represent this as one recurrence relation? $ m$ cannot grow beyond constant $ k$ .

How can instruction fetch and decode pipeline stages run simultaneously in a CPU with dynamic branch prediction?

I have recently been investigating CPU pipelining and branch prediction and have a question about how exactly these fit together.

If, for example, instructions are meant to be fetched in one stage of the pipeline and decoded in the next while the next instruction is fetched simultaneously, how is it possible for the pipeline to proceed without a stall when dynamic branch prediction is in operation?

As an instruction must be decoded before branch prediction can occur or be deemed unneeded, and as any prediction must be made before the next instruction can be fetched, how can an instruction be decoded while the next instruction is fetched in the same clock cycle?

What does ‘recursion with no explicit stages’ mean in relation to dynamic programming?

I have the following excerpt from one of my assignments, essentially asking me to build on a previous formulation. However, while I can think of improvements, I have no idea if they fit the ‘no explicit stages’ category. Wondering, if anyone knew what that meant?

The colleague has also suggested to you that the deterministic DP approach above is not efficient, and that recursion with no explicit stages (or just 1 stage, if you prefer) may lead to a more efficient algorithm.

Why reverse pipeline stages in cycle-level simulator?

In pipeline simulator exercise, it says that:

Traversing the stages in backwards order simplifies the instruction flow through the pipeline.

Also, in gpgpu-sim source code, the stages are reversed (line 2442):

void shader_core_ctx::cycle() {     m_stats->shader_cycles[m_sid]++;     writeback();     execute();     read_operands();     issue();     decode();     fetch(); } 

Why? What problem it solves? Can anyone elaborate a bit or give a pointer to books/papers on this particular “trick”?

Many thanks!

How to set up a multi-master MongoDB in stages?


We are building a web solution that will be used globally. To support the eventual target audience we are trying to design the solution so that it’s hosted in 3 different data centers. users will be routed to the closest server based on location data.

Having said that, to start, we will only deploy this solution to one datacenter, and only users from North America will have this solution available to them.

Technology Set

MongoDB and RethinkDB have has been short listed for the database. We need something that allows multi-master replication, since we need to be able to read and write to the database from any one of the data centers.


Management wants something delivered in two weeks. The same usual story. They over committed us… under staffed etc.

I need to come up with a design that’s future proof. I’m not familiar enough with MongoDB yet to be confident that I’ve identified all the pieces that I need to deliver right now, and still be future proof.

What I think I know So Far

I think in MongoDB terminology, each data center is a zone. In the final solution, I will have one zone per data center, and in each zone, I will have a primary shard. So in the North America zone, I will have shard A… and that is it’s primary shard. Shard A will be replicated to the Asia Zone… so that if the north american data center goes down, Asia will have it’s data and can kick in.

I also understand that I need to be careful with the shard keys because once I create them, I can’t change them. So I’m thinking of somehow creating a shard based on location. I will know that a request is coming from japan, I send it the “asia” dc, but if it’s coming from France, it’s gonna hit the European DC.

Specific Questions

I’m reading this article; Do I need a mongos router in each data center? What about the config server? If I start with just creating “shard A” in Zone North Am, what priority do i give it? Can I worry about priority later?

I’m still mulling things over so I’m sure there are questions I should be asking that I haven’t even thought of yet. If you have any comments or suggestions, I’m all ears. Thank you
