actually, beta is less useful than that! I think it represents the median difference between the two distances, its not a tolerance (at least as far as I can recall after experimenting with tuning this value). As with you, I have found that

it should be in seconds - the problem is that the paper assumes that the 'great circle' (straight line) distance between two points should be almost the same as the 'route' distance between those points, with an exponent

yep - look up 'Hidden Markov Map Matching through Noise and Sparseness' by Krumm and Newson it calculates the final probability by combining 'emission' probabilities (the probability that a GPS observation was on a parti

When I first used Parallels years ago I was pretty surprised how close to native it could run Windows (though not 3D graphics intensive apps, as far as I can recall.) I tried running it recently though and the performance was _abysmal_. Jus

(I went to bed so didn't take long to reply before) I am clearly not expressing myself well. I am talking about a situation where some stakeholders are expecting a complete picture of roughly how large the project is and would like to

by cechner 10y ago
it is totally reasonable for stakeholders to want to track your progress through a project. If you have a good way of doing that then great, you should use that. Scrum people believe that scrum is the simplest way of measuring that. But at

(replying here because I guess we've reached the maximum depth) I am here assuming that you want to be able to try to measure your progress through the project (as I mentioned, this is the only thing scrum does for you). Both of you se

can we infer that he would like to give his estimates: * while he is actually writing the code (so not up front) * not in a group setting but as an individual, so either one person estimating the whole thing or each person giving different

It sounds as though you objecting to being required to give any estimate at all.

by cechner 10y ago
if its being used to 'get velocity up' instead of measuring velocity then its not being done right. I personally think estimating projects is one of the most difficult things about this industry. Especially if we're talking a

If you're objecting to people who treat scrum (or any project management tool) as a one-stop-shop that will cure all ills I agree with you, but nobody here is saying that. If you are objecting to defining the scope as small tasks and m

if pressure is ramping up and quality down the sprints arent serving their purpose. One of the few defining characteristics of scrum is that the developers define how much they can achieve, and this estimation is improved over time. If this

I agree, it is often not the best approach. But many situations demand a well defined approach to estimation and although the OP tried to preempt this, he didnt provide an alternative

oh and I have attended some of those expensive Scrum 1-week courses and saw the darker side of that community - it definitely has a cult following that give it a bad name, but I've been to similar conventions around design patterns, ob

Scrum proponents (a label I would tentatively apply to myself) would tell you that 'you're doing it wrong' but unfortunately a point-by-point reply to this article would detract from the general problem here: Scrum is intende

I dont really understand this. "NF_REQ_00: API must not change" Add verification tests to ensure API remains as documented. Every time someone checks in code your tests are run, break if something changes. Every project has functi

interesting - I recently heard someone call it a forecast and thought 'man why don't they use that term in scrum?' Nice to know that they actually do (I havent read up on it in some time, probably should)

edit: I just noticed they said 'sprint commitment', and that they should adhere to it even if it runs overtime. This is probably the most wrong part of the article - you get done what you can, and let it affect your velocity. It i

I don't really agree with this - Scrum isn't really easy to do but in many situations it is the simplest approach to take. If you need to monitor your progress in 'real' terms (i.e., whats actually completed) Scrum is pr
